Applying the Arrow-Debreu-Mundell-Fleming model as an economic standard model, with combining axiological framework and epistemological model, it is proposed to analyze economic policies with using a synthetic model, where interest, exchange and tax rates are integrated together. Except normal monetary and fiscal policies mainly via interest and tax rates, there are feasible ways to utilize modified strategies via exchange and tax rates. When ones need to simulate national local market, ones can raise the exchange rate. Otherwise, when ones need to promote international global trade, ones may lower the exchange rate. It is found that tax reduction is good policy when tax rate is higher than normal and that tax increase is good social policy when tax rate is lower than normal, during economic depression. Also it is revealed that tax reduction is good social policy when tax rate is lower than normal, and that tax increase is good policy when tax rate is higher than normal, during economic overheat. While economic system seeks efficiency and social system pursues equality, common interest modifications with elastic exchange and tax rates could be applied for balancing efficiency and equality.

CAUSALITY EFFECT OF ENERGY CONSUMPTION AND ECONOMIC GROWTH IN NIGERIA (1980-2...paperpublications3
Abstract: This paper investigates the causality effect of energy consumption and economic growth in Nigeria using annual data from the World Bank Development Indicator and CBN Statistical Bulletin from1980 to 2012.The paper adopts Vector Auto Regressive (VAR) and Error Correction Model (ECM) to test the causality between energy consumption and economic growth in Nigeria. The order of integration of the variables was determined using Augmented Dickey Fuller (ADF) test and the DF-GLS test which was followed by co-integration and causality test. Our findings suggest a positive relationship between energy consumption and economic growth. There is no causality between energy consumption and economic growth in the short run; in the long run we find unidirectional causality running from Economic growth to Energy consumption. There is need for government to diversify the energy mix to include all the untapped potentials of renewable power options such as small hydro, wind, solar and biomass among others in all the states and local constituencies. Energy conservation policy is necessary to adopt if this causality is running from per capita GDP to energy consumption but policy should be designed in a way that energy conservation measures do not adversely affect the economic growth.
Keywords: Causality, Economic Growth, Energy consumption, Energy Conservation Policy, Error correction Model, Per Capita GDP.
The Causal Analysis of the Relationship between Inflation and Output Gap in T...inventionjournals
The purpose of the paper is to study dynamic relationships between the inflation and output gap by using Granger causality, Impulse response and variance decompositions analysis within VECM framework for the quarterly data over the first period of 2003 and second period of 2016. The results of the study indicate that the output gap Granger cause the inflation in Turkey both in short-and long-runs. Also, sign of the causality is negative and same causal relationships between two variables hold beyond the sample period. The results should be taken as an evidence of the conclusion that the output gap has important implications for the CBRT's monetary policy.
This study examines whether economic stability in Indonesia capable predicted by the model Mundell-Fleming. Prediction proxy stability of the interaction of fiscal and monetary policy. During Indonesia's economic stability is largely determined by the strength of economic fundamentals, while economic fundamentals are strongly influenced by fiscal and monetary policies. Therefore flemming Mundell predicts how strong the economic stability in Indonesia ?, the statement in the analysis by using a long-term predictions are Vector Autoregression. Research findings indicate patterns of interaction predictions variety of fiscal and monetary policy, both short term, medium term and long term. It turned out that fiscal policies are derived from taxes are more effective than government spending to control economic growth, investment and inflation, but government spending is more effective to control the exchange rate. The monetary policy of interest rates more effectively control the exchange rate and inflation, while the money supply is more effective in controlling the growth of economy and investment.

The IMF has based much of it policies on a theoretical framework developed by Polak, Mundell, and Fleming over fifty years ago. Their models were based on a set of assumptions that a do not reflect the economic realities in the developing countries. The IMF’s insistence on demand management policies created policy “blind spots” that prevented it’s acknowledgment of causes of macroeconomic imbalances other than government fiscal mismanagement. There has been some movement toward reform by the Fund and better alignment with its sister organization, the World Bank. Just as the East Asian crisis momentum for change, recent events seem to have created a significant shift in the thinking of the Fund’s staff and policy analyst. The recent global crisis has caused the Fund to acknowledge the limits of monetary policy and bring fiscal policy “center stage” as an important countercyclical tool. In short, the crisis has “exposed flaws in the pre-crisis policy framework” [Carlos E. Guice, Sr.]

This study examined the influence of the characteristics of the audit committee on Palestinian firms’ value. The research explores precisely the effect on the Audit Committee characteristics’ efficiency, namely, independence, expertise, evaluating the relationship among dependent and independent variables. Secondary data collected from a list of companies were registered in the Palestine Stock Exchange from 2011 to 2018. Individual variables considered are the independence & expertise of the audit committee, whereas the ROA is employed as the dependent variable as an indicator of a firm’s value. The results showed that the Audit Committee’s independence & expertise substantially positive with ROA. The study concluded that the audit committee’s characteristics are enhancing firm performance. The implications of this study’s findings can be used by decisions and policymakers, the firm’s management, and other stockholders’ interests to create reliable ties between agents and the principals.
There is increasing acceptability of emotional intelligence as a major factor in personality assessment and effective human resource management. Emotional intelligence as the ability to build capacity, empathize, co-operate, motivate and develop others cannot be divorced from both effective performance and human resource management systems. The human person is crucial in defining organizational leadership and fortunes in terms of challenges and opportunities and walking across both multinational and bilateral relationships. The growing complexity of the business world requires a great deal of self-confidence, integrity, communication, conflict, and diversity management to keep the global enterprise within the paths of productivity and sustainability. Using the exploratory research design and 255 participants the result of this original study indicates a strong positive correlation between emotional intelligence and effective human resource management. The paper offers suggestions on further studies between emotional intelligence and human capital development and recommends conflict management as an integral part of effective human resource management.
This paper examines the role of loan characteristics in mortgage default probability for different mortgage lenders in the UK. The accuracy of default prediction is tested with two statistical methods, a probit model and linear discriminant analysis, using a unique dataset of defaulted commercial loan portfolios provided by sixty-six financial institutions. Both models establish that the attributes of the underlying real estate asset and the lender are significant factors in determining default probability for commercial mortgages. In addition to traditional risk factors such as loan-to-value and debt servicing coverage ratio lenders and regulators should consider loan characteristics to assess more accurately probabilities of default.
This study examined the impact of financial innovation on money demand in Nigeria, using quarterly time series for the period 2009-2019. The dependent variable was money demand, represented by broad money, while the independent variable was financial innovation represented by modern payment channels such as volume of Automated Teller Machines (ATMs) transactions, volume of Point of Sales (POS) transactions, volume of Internet banking transactions, and volume of Mobile banking transactions. The study employed the ordinary least squares (OLS) regression technique as the estimation method within the cointegration, granger causality, and error correction modeling. The result obtained showed that financial innovation has mixed impact on money demand in Nigeria during the period of analysis. For instance, financial innovation has positive impact on money demand through volume of ATM transactions in the current period, two periods lagged of volume of mobile banking transactions, current period and one period lagged of volume of internet banking transactions, and current period’s volume of Point of Sales (POS) transactions in Nigeria. On the other hand, financial innovation has negative impact on money demand through one period lagged of volume of point of sales in Nigeria. On the stability of the demand for money function, the result of the stability tests based on the CUSUM test and CUSUM of squares test showed that the demand for money function was stable during the evaluation period. The study recommended that monetary policy strategy of the central bank of Nigeria (CBN) should be fine-tuned to ensure it is well suited to deal with the challenges posed by financial innovation by way of proliferation of sophisticated payment channels.
Equity financing is one of the sources of funding available to non-bank financial institutions which is quite prevalent in developed financial markets for small or start-up firms. This study empirically determined the effect of the Equity Financing Scheme on a sustainable increase in productivity of agro-allied small businesses in Nigeria. Data for this study were elicited through the use of a questionnaire structured in a five-point likert scale. The evaluation of the relationship between the dependent and independent variables was performed using the Ordinary Least Square regression technique. The study revealed that the equity financing scheme had a positive and significant effect on the sustainable productivity of agro-allied small businesses in South-South Nigeria. The study recommended that efforts should be made to educate the small business entrepreneurs on the benefits of equity financing as a viable option towards business growth and expansion and that the government through the various intervention agencies should restructure the long-term loan policies to give access to more growth-oriented agro-allied businesses, to increase their presently low capacity to procure heavy-duty technology to increase productivity and achieve food security in Nigeria. Small business owners should take advantage of the membership of cooperative societies and as well maintain good business relationships with suppliers; this will guarantee a continuous supply of needed materials and uninterrupted operations of the business.
This study seeks to evaluate the impact of public borrowing on economic growth in Nigeria using time series data from 1980 to 2018. Specifically, the study seeks to analyze the effect of domestic debt (proxy by Federal Government Bonds-FGB) and external debt (proxy by International Monetary Fund Loan-IMFL) on Nigerian’s Gross Domestic Product (GDP). To achieve this objective, secondary data was collected from the Central Bank of Nigeria Statistical bulleting and the Debt Management Office of Nigeria. A multiple regression model involving the dependent variable (GDP) and the independent variables (FGB and IMFL) was formulated and subjected to econometric analysis. These variables were adjusted with the Jarque-bera test of normality while the correlation result was used to check the possibility of multi-collinearity among the variables. The t-test was used to answer the research questions and test the formulated hypotheses at the 5percent statistical level. Results from the analysis show that a positive relationship exists between IMF Loan and Nigeria’s gross domestic product, while a negative relationship exists between FG Bonds and Nigeria’s gross domestic product, which violates the Keynesian theory of public debt. The study concludes that both domestic and external debt significantly affect economic growth in Nigeria. Therefore, it was recommended that public borrowing should be efficiently used and contracted solely for economic reasons and not for social or political reasons as this will help to avoid accumulation of debt stock over time.
Equity investment financing is an innovative way of financing the real sector which has considerable developmental potential. The study empirically determined the effect of Equity investment financing on sustainable increase in productivity among agro-allied small businesses in South-South Nigeria. The instrument of data collection is the research questions structured in a five-point likert scale. The evaluation of the relationship between the dependent and independent variables was performed using the Ordinary Least Square regression technique. The study revealed that equity investment financing has a positive and significant effect on the sustainable productivity of businesses in Nigeria. The study recommended educating small business entrepreneurs on the benefits of equity financing as a viable option towards business growth and expansion and that the government through the various intervention agencies should restructure the long-term loan policies to give access to more growth-oriented agro-allied businesses, to increase their presently low capacity to procure heavy-duty technology to increase productivity and achieve food security in Nigeria. Small business owners should take advantage of the membership of cooperative societies and as well maintain good business relationships with suppliers; this will guarantee a continuous supply of needed materials and uninterrupted operations of the business.
This paper aims to explore the relationships of the performance of producer responsibility organizations (PROs) for waste oil, waste electrical and electronic equipment (WEEE), and end-of-life vehicles (ELV). The methodology consists in estimating the cointegration equations between the variables of lubricating oil production (SIG), electric and electronic equipment (EEE), and vehicle production (VP) using dynamic ordinary least squares (DOLS). Subsequently, elasticities are got based on estimates for Spain over the period 2007-2019 using quarterly data. The main results were that SIG and EEE were cointegrated variables. The elasticity of the SIG variable up to EEE was positive at 2, 4166. Additionally, the elasticity of the SIG variable up to VP was 2, 4050. However, SIG and VP are not cointegrated variables; subsequently, it was not a stable relationship between these variables. Results suggest it was because EPR was applied in WEEE PRO join with a deposit refund system (DRS); meanwhile, EPR in ELV PRO had been applied without subsidies to purchase cars.
In the process of R&D globalization, due to market demand and preferential policies, many multinational companies choose to invest in R&D in China. With the increase of labor costs in coastal areas and the rapid economic development of the central and western regions, multinational companies have already shifted from coastal areas to central and western regions when choosing R&D regions in China, especially in Shaanxi Province. Therefore, studying the character of R&D investment and operating performance of Multinational Corporation in Shaanxi Province has important practical significance. This article uses the data of the R&D investment of multinational corporation in the joint annual inspection of Shaanxi Province in 2018 as the sample and uses EXCEL software to conduct data analysis to gain an in-depth understanding of the character of R&D and investment of multinational corporation in Shaanxi Province, business characteristics and business performance. And it is concluded that the R&D investment of multinational corporation in Shaanxi Province has a series of characteristics such as concentration of distribution, concentration of enterprise scale, and overall good performance of operating performance.
In Bangladesh, migrant worker’s remittances constitute one of the most significant sources of external finance. This paper investigates the existence of relation between remittance inflow and GDP and the causal link between them in Bangladesh by employing the Granger causality test under a VECM framework. Using time series data over a 38 year period, we found that growth in remittances does lead to economic growth in Bangladesh. In addition to the relationship, this paper also points out some issues that are working as impediments in getting remittance and give some recommendations to overcome those impediments.
In the context of the 4.0 revolution, technology applications, especially cloud computing will have strong impacts on all areas, including accounting systems of enterprises. Cloud computing contributes to helping the enterprise accounting apparatus become compact, help automate the input process, improve the accuracy of the input data. Besides, the issur of accounting, reporting, risk control and information security also became better, contributing to improving the effectiveness of accounting. However, besides the positive impacts, businesses also face many difficulties in deploying and applying cloud computing. However, this application requirement will become an inevitable trend contributing to improving the operational efficiency of enterprises. To promote this process requires from the State as well as businesses themselves must have awareness and appropriate decisions. Breakthroughs in information technology have dramatically changed the accounting industry and the creation of financial statements. The Internet and the technologies that use the power of the Internet are playing an important role in the management and accounting activities of businesses - who always tend to be ready to receive and use public innovations technology in collecting, storing, processing and reporting information.
In recent years, Vietnam has joined international intergration by strong export agreements of bilateral and multilateral; Vietnam’s merchandise export in 1995 was only US $5.4 billion, in 2018 Vietnam’s merchandise export increased by 45 times compared to 1995 with US $244 billion. Vietnam’s imports increased by 29 times in 2018 compared to 1995. This study is an attempt to test a method of estimating the influence of exports on several Supply-sidefactors such as production value, value added and imports through the expansion of the standard system W. Leontief I.O and Miyazawa-style economic-demographic relations. This study also tries to make an experiment in the “Leontief Paradox”.The result is that Vietnam’s export value spread to production and imports but spread low to added value, especially in the processing industry group’s fabrication. The study is based on the non-competitive I.O table in 2012 and 2018 with 16 sectors.
The profitability of commercial banks is influenced by a number of internal and external factors. This paper attempts to identify the internal factors which significantly influence the profitability of commercial banks in Bangladesh. In this study, profitability is measured by ROA and ROE which may be significantly influenced by the internal factors such as IRS, NIM, CAR, CR, DG, LD, CTI and SIZE of the bank. Data are collected from published annual reports during 2014--2018 of 23 commercial banks. Using simple regression model, it is found that CR has significant effect on the profitability and CAR has significant influence on ROA only. In addition to this, DG has significant effects on PCBs’ profitability (ROE only) where as IRS and CTI have significant influence on profitability (ROA only) of ICBs. Further, none of these variables have significant effects on the profitability of SCBs but CAR and CR are correlated with profitability (ROA only) and the causes may be the nature of services provided by SCBs to its clients. The internal policy makers should manage the influential internal factors of the banks in order to increase their profitability so that they can meet stakeholders’ expectations.
Using a series of econometric techniques, the study analysed interaction between monetary policy and private sector credit in Ghana. This study made use of monthly dataset spanning January 1999 to December 2019 of credit to the private sector (PSC) and broad money supply (M2). The results reveal that there exists cointegration, a long run stationary relation between monetary policy and private sector credit. This implies, increases in credit should prompt long-term increases in monetary policy. It is not surprising that growth in the private sector might have a stronger effect on monetary policy. The Error Correction Test is statistically significant and that all the variables demonstrate similar adjustment speeds. This implies that in the short run, both money supply and credit are somewhat equally responsive to their last period’s equilibrium error. There is unidirectional causation from private sector credit to monetary policy. It can be said that, there is an interaction between money supply and private sector credit. Thus, credit to private sector holds great potential in promoting economic growth. It can be recommended to the government to increase the credit flow to the private sector because of its strategic importance in creating and generating growth of the economy.
This paper investigates if forecasting models based on Machine Learning (ML) Algorithms are capable to predict intraday prices in the small, frontier stock market of Romania. The results show that this is indeed the case. Moreover, the prediction accuracy of the various models improves as the forecasting horizon increases. Overall, ML forecasting models are superior to the passive buy and hold strategy, as well as to a naïve strategy that always predicts the last known price action will continue. However, we also show that this superior predictive ability cannot be converted into “abnormal”, economically significant profits after considering transaction costs. This implies that intraday stock prices incorporate information within the accepted bounds of weak-form market efficiency, and cannot be “timed” even by sophisticated investors equipped with state of the art ML prediction models.
In recent times, agricultural sector has returned to the forefront of development issues in Nigeria given its contribution to employment creation, sustainable food supply and provision of raw materials to other sectors of the economy. In lieu of that, this study examines the impact of agriculture on the economic growth in Nigeria using annual time series data covering the sample period of 1981 to 2018. To analyse the data collected, Autoregression Distributed Lag (ARDL) model through the bounds testing framework is employed to measure the presence of cointegrating relations between real GDP, agricultural productivity, labour force, and agricultural export. Results show the presence of both short-run and long-run relationship among the variables, and that agriculture has a positive and significant impact on economic growth in Nigeria. These findings inform the Nigerian government on the need to expedite labour force (human capital) and agricultural export (non-oil) development with the view to achieving sustainable growth and development. In addition, developing skills and competencies of labour force through capacity building in the agricultural sector will encourage research and development thereby increase the export size, hence essential for long-term growth.
The article illustrates the results of the economic development of the first fifteen years of the XXI century under the conditions of unprecedented economic freedom, globalization and the appearance of new informational sectors up to and including the first attempts at revising liberalism. The analysis of statistical data demonstrates an obvious increase in the percentage of well-off people in many countries as well as the increased economic capabilities of small, medium and large businesses, whose assets are distributed among an ever-increasing number of owners. This provides the impetus to review our collective approach to liberalization and globalization, as well as to view its unexpected strong sides that make human progress possible.
This paper investigates the relationship between working capital management and financial performance of Pharmaceuticals and Textile firms listed at the Dhaka Securities Exchange in Bangladesh. The data analysis was carried on ten Pharmaceuticals and Textile firms for a period of 2013 to 2017. Secondary Data was analyzed by applying Descriptive Statistics, Regression and Correlation analysis to findthe relationship of current ratio, inventory conversion period and average payment period with Return on Asset. The findings indicate that the Pharmaceuticals and Textile firms’ performance is influenced by the variables relating to working capital. There is a positive relationship between profitability and current ratioand Inventory Turnover period shows a negative relationship with profitability but Average payment period shows insignificant impact on profitability. The study concludes that there exists a relationship between working capital managementand financial performance of Pharmaceuticals and Textile firms in Bangladesh. The study recommends that for the Pharmaceuticals and Textile firms to remain profitable, they should employ working capital management practice that will help in making decisions about investment mix and policy, matching investment to objective, asset allocation for institution and balancing risk against profitability.
Organizational behaviour involves the design of work as well as the psychological, emotional and interpersonal behavioural dynamics that influence organizational performance. Management as a discipline concerned with the study of overseeing activities and supervising people to perform specific tasks is crucial in organizational behaviour and corporate effectiveness. Management emphasizes the design, implementation and arrangement of various administrative and organizational systems for corporate effectiveness. While the individuals, and groups bring their skills, knowledge, values, motives, and attitudes into the organization, and thereby influencing it, the organization, on the other hand, modifies or restructures the individuals and groups through its structure, culture, policies, politics, power, and procedures, and the roles expected to be played by the people in the organization. This study conducted through the exploratory research design involved 125 participants, and result showed strong positive relationship between the variables of interest. The study was never exhaustive due to limitations in terms of time and current relevant literature, therefore, further study could examine the relationship between personality characteristics and performance in the public sector, where productivity is not outstanding, when compared with the private sector. Based on the result of this investigation it was recommended that organizations should provide emotional intelligence programmes for their membership as an important pattern of increasing co-operative behaviours and corporate effectiveness.
This paper scrutinizes Determinants of Capital Structure: A study on some selected corporate firms in Bangladesh. We have taken 10 out of 37 listed companies of DSE dividing into two sectors i.e. Pharmaceuticals and chemicals and Tannery sector, five years data from 2013 to 2017 has been collected from respective annual reports. Total number of observations was 50. There are different factors that affect a firm's capital structure decision. We use leverage (D/E ratio) as dependent variable and independent variables are profitability, tangibility, tax, size, growth, non-debt tax shield (NDTS) and financial costs. By using Descriptive Statistical Analysis, Correlation Analysis and Regression Analysis tools we find that Tangibility, size, NDTS, and financial costs are positively related with leverage and Profitability, tax, and growth are negatively related with leverage. In our analysis we see profitability, tangibility of asset, growth and non-debt tax shield have significant association. So when we take capital structure decision of the above firms we should consider profitability, tangibility of asset, growth and non-debt tax shield because other independent variables are insignificant in the context of Bangladesh economy.

what is the future of Pi Network currency.DOT TECH
The future of the Pi cryptocurrency is uncertain, and its success will depend on several factors. Pi is a relatively new cryptocurrency that aims to be user-friendly and accessible to a wide audience. Here are a few key considerations for its future:
Message: @Pi_vendor_247 on telegram if u want to sell PI COINS.
1. Mainnet Launch: As of my last knowledge update in January 2022, Pi was still in the testnet phase. Its success will depend on a successful transition to a mainnet, where actual transactions can take place.
2. User Adoption: Pi's success will be closely tied to user adoption. The more users who join the network and actively participate, the stronger the ecosystem can become.
3. Utility and Use Cases: For a cryptocurrency to thrive, it must offer utility and practical use cases. The Pi team has talked about various applications, including peer-to-peer transactions, smart contracts, and more. The development and implementation of these features will be essential.
4. Regulatory Environment: The regulatory environment for cryptocurrencies is evolving globally. How Pi navigates and complies with regulations in various jurisdictions will significantly impact its future.
5. Technology Development: The Pi network must continue to develop and improve its technology, security, and scalability to compete with established cryptocurrencies.
6. Community Engagement: The Pi community plays a critical role in its future. Engaged users can help build trust and grow the network.
7. Monetization and Sustainability: The Pi team's monetization strategy, such as fees, partnerships, or other revenue sources, will affect its long-term sustainability.
It's essential to approach Pi or any new cryptocurrency with caution and conduct due diligence. Cryptocurrency investments involve risks, and potential rewards can be uncertain. The success and future of Pi will depend on the collective efforts of its team, community, and the broader cryptocurrency market dynamics. It's advisable to stay updated on Pi's development and follow any updates from the official Pi Network website or announcements from the team.

Empowering the Unbanked: The Vital Role of NBFCs in Promoting Financial Inclu...Vighnesh Shashtri
In India, financial inclusion remains a critical challenge, with a significant portion of the population still unbanked. Non-Banking Financial Companies (NBFCs) have emerged as key players in bridging this gap by providing financial services to those often overlooked by traditional banking institutions. This article delves into how NBFCs are fostering financial inclusion and empowering the unbanked.
how can I sell pi coins after successfully completing KYCDOT TECH
Pi coins is not launched yet in any exchange 💱 this means it's not swappable, the current pi displaying on coin market cap is the iou version of pi. And you can learn all about that on my previous post.
RIGHT NOW THE ONLY WAY you can sell pi coins is through verified pi merchants. A pi merchant is someone who buys pi coins and resell them to exchanges and crypto whales. Looking forward to hold massive quantities of pi coins before the mainnet launch.
This is because pi network is not doing any pre-sale or ico offerings, the only way to get my coins is from buying from miners. So a merchant facilitates the transactions between the miners and these exchanges holding pi.
I and my friends has sold more than 6000 pi coins successfully with this method. I will be happy to share the contact of my personal pi merchant. The one i trade with, if you have your own merchant you can trade with them. For those who are new.
Message: @Pi_vendor_247 on telegram.
I wouldn't advise you selling all percentage of the pi coins. Leave at least a before so its a win win during open mainnet. Have a nice day pioneers ♥️

Fig-1. An axiological framework supported by tax, interest and exchange ratios
In Figure 1, the nodes represent subjects and ratios, while the links denote relations with axiological views,
where individuals work towards happiness, nations act towards powerfulness and enterprises want profit for
supporting nation and individual (marked by S). In the economic system, both banks and enterprises need efficiency,
and the nation or society needs equality, while individual behaviors are affected by national policies and goods-
money supply as well as all ratios based on money. It is expected that the framework will work towards the
axiological good.
3. Epistemological Methodological Model
As a mathematical description of general equilibrium of economic markets, Arrow-Debreu model (Arrow and
Debreu, 1954) explains microfoundations of economics, while Mundell-Fleming model (Fleming, 1962; Mundell,
1963) supplies macroeconomic images of goods and finance (Friedman and Hahn, 2000; Jones and Kenen, 1985).
However, these two important models ignored necessary relations in linking each other, as if macroeconomics lost
its microfoundations (Forni and Lippi, 1997; Weintraub, 1977;1979) or microeconomics never knew macroeconomic
language. For better economic policy analysis (Scarth, 2014), we need a unified micro-macro-economic model as
unified economics. Therefore, it is suggested to apply Arrow-Debreu-Mundell-Fleming model as an economic
standard model (Ye, 2015).
Arrow–Debreu (A-D) model is a mathematical economic model under certain economic assumptions (i.e.
convex preferences, perfect competition and demand independence), which suggest that there must be a set of prices
to allow aggregate supplies to equal aggregate demands for every commodity in economic system. The model is the
central theory of general economic equilibrium and it is often used as a general reference for other microeconomic
models. The A–D model is one of the most general models of competitive economy and is a crucial part of general
equilibrium theory, as it can be used to prove the existence of general equilibrium (or Walrasian equilibrium) of an
economy. In general, there may be a lot of equilibria. However, with extra assumptions on consumer preferences, to
be specifical, their utility functions are strongly concave and twice continuously differentiable, a unique equilibrium
exists.
Meanwhile, Mundell–Fleming model is described in terms of an IS-LM-BP graph with the domestic interest rate
plotted vertically and real GDP plotted horizontally, where IS curve represents the equilibrium of product market,
LM curve means the equilibrium of money market and BP addresses the balance of payments or international
income-payment. Geometrically, the IS curve is downward sloped and the LM curve is upward sloped, while the BP
curve is upward sloped unless there is perfect capital mobility, in which case it is horizontal at the level of the world
interest rate.
In the IS-LM-BP graph, under less than perfect capital mobility the positions of both the IS curve and the BP
curve depend on the exchange rate, since the IS-LM graph is actually a two-dimensional cross-section of a three-
dimensional space involving all of the interest rate, income, and the exchange rate. Under perfect capital mobility the
BP curve is simply horizontal at the level of the domestic interest rate equal to that of the world interest rate. In pure
IS-LM model, the domestic interest rate is a key component for keeping both the money market and the goods
market in equilibrium. However, differenciated from the pure IS-LM model, Mundell–Fleming model adds
international financial elements, for fitting the open economy assumption.
Among the relative economic rates, interest rate γ, exchange rate π, and tax rate τ are important factors (Floyd,
2010; Sánchez, 2005) in determining economic running. The inflation rate λ and unemployment rate η are also
3. International Journal of Economics and Financial Research
161
important factors to reflect economic properties and qualities. To avoid confusing with imaginary unit and time,
Greek alphabetic γ, π and τ are applied to denote interest rate, exchange rate and tax rate respectively.
However, not every relative economic rate is independent, though we have no clear relations among these rates.
We have only Dombusch’s formula (Dornbusch, 1976) for describing a relation linking γ* as real rate of interest and
π* as real exchange rate, via nominal interest rate γ and exchange rate π, where they are integrated in vertical
coordinate within a quasi-linear relation as approximate formula as follows
1
*
*
(1)
Meanwhile, the relation between the real interest rate, the nominal interest rate, as well as inflation rate is
described by famous Fisher equation as
1
1
*1
(2)
In the Fisher equation, γ and γ* respectively refer to the nominal and real interest rate, and λ means the inflation
rate. Since 1+γ=(1+γ*)(1+λ)=1+γ*+λ+γ*λ and γ*λ<<γ*+λ, there is linear approximation γ* ~ γ – λ (Feldstein,
1976). Moreover, the inflation rate links with unemployment rate via Phillips curve.
In a proposed synthetic model (Ye, 2017), Mundell–Fleming model (Fleming, 1962; Mundell, 1963), money
supply-demand model and Laffer curve (Laffer, 2004) are integrated into a unified framework of interest, exchange
and tax rates. The synthetic analytical model is basically illustrated in Figure 2.
Fig-2. The synthetic model integrating interest rate, exchange rate and tax rate
When a steady-state economy is characterized by the inflation rate λ, the nominal rate of interest γ and the real
rate of interest γ* are linked by linear relation γ*=γ – λ. If the elasticity of expectations σ is less than unity, there is

Above synthetic model includes following three parts:
The first part is Mundell–Fleming model, characterized by IS–LM-BP curves, described by the domestic interest
rate plotted vertically and real GDP (Y) plotted horizontally, where IS curve represents the equilibrium of product
market, LM curve means the equilibrium of money market, and BP addresses the balance of payments or
international income-payment. Geometrically, the IS curve is downward sloped and the LM curve is upward sloped,
while the BP curve is upward sloped unless there is perfect capital mobility, in which it is horizontal at the level of
the world interest rate. In the IS-LM-BP graph, under less than perfect capital mobility, the positions of both the IS
curve and the BP curve depend on the exchange rate, since the IS-LM graph is actually a two-dimensional cross-
section of a three-dimensional space involving all of the interest rate, income, and the exchange rate. Under perfect
capital mobility, the BP curve is simply horizontal when the level of the domestic interest rate is equal to the world
interest rate level. In the pure IS-LM model, the domestic interest rate is a key component for keeping both the
money market and the commodity market in equilibrium. However, unlike the pure IS-LM model, Mundell–Fleming
model adds the international financial elements to fit to the open economy assumption.
4. International Journal of Economics and Financial Research
162
The second part is the money demand and supply curve, where the demand curve of money illustrates the
quantity of money demanded at a given interest rate. Generally, the demand curve of money is downward sloping,
which means that people want to hold less of their wealth in the form of money when interest rates on bonds and
other alternative investments are higher The supply curve of money illustrates the quantity of money supplied at a
given interest rate. Unlike a typical supply curve in the commodity market, the supply curve of money could be
vertical, because it might not depend on interest rates. In fact, it depends entirely on decisions made by the central
bank, as the central bank controls the supply of money. However, the market mechanism could also introduce the
demand-supply interaction into the money market to illustrate the money demand and supply with using normal
demand-supply curves. The equilibrium in the money market takes place when the quantity of money demanded is
equal to the quantity supplied. Since there are complex relations between interest and exchange rates (Floyd, 2010;
Sánchez, 2005), for simplifying discussed issues, it is designated that real exchange rate and nominal interest rate are
linked by γ↑→π*↑, characterized by national money vs. foreign money, in other words, interest and exchange rates
keep changes in the same direction.
The third part is Laffer curve, which is one possible representation of the relationship between rates of taxation
and the hypothetical resulting levels of government revenue. Because the government revenue is proportional to
GDP, I translate the Laffer curve into the coordinate system with tax rate plotted down-vertically and real GDP (Y)
plotted horizontally here. Following claims to illustrate the concept of taxable income elasticity, taxable income will
change in response to changes in the rate of taxation.
Thus, the synthetic model integrates interest, exchange and tax rates, where interest and exchange are plotted
up-vertically with different calibration in the same direction, while tax rate is plotted down-vertically. The Mundell–
Fleming model (IS–LM-BP curves) is set in the first quadrant; the money supply-demand model occupies the second
quadrant; and the Laffer curve is arranged in the fourth quadrant. It is valuable to emphasize that interest rate can be
changed by artificial operations via bank in a discontinuously way, while the exchange rate randomly changes
following market, and tax rate is rigidly determined by laws, mostly.
By combining Figure 1 and Figure 2, the good policies can keep balance between demand and supply,
consumption and production, rich and poor, as well as the true and the good. At the level of nation, reducing tax is
the good policy for raising social welfare, and increasing tax is also the good policy for balancing rich and poor. At
the level of individual, stable consumption and tax payment are the good behaviors. At the level of bank/enterprise,
interest/profit-increase is the good strategy during economic growth and inversely interest/profit-decrease is the good
strategy during economic decline. At all levels, epistemological true and axiological good are combined, for
balancing economic efficiency and social equality.
4. Three Key Linkages to Unify Micro-Macro-Economics
According to Weintraub’s conclusion, Arrow-Debreu general equilibrium model (Walrasian equilibrium model)
has the following characteristics (Weintraub, 1977)1
(1) There is a class of agents, called consumers, who have preferences over different bundles of final goods.
(2) The consumer preferences are sufficiently regular so that preferences can be represented by utility
indicators.
(3) Consumers’ income comes from sales of factor services and distributed profits of firms.
(4) Members of another class of agents, called firms, have preferences over output configurations, which lead
to profits.
(5) Consumers, taking product and factor prices as given, attempt to maximize utility subject to their income
constraint.
(6) Firms, taking product and factor prices as given, attempt to maximize profits subject to technology
constraint.
Those mean that we have the first key to link microeconomic foundations with macroeconomic results, via the
relation of demand and supply.
4.1. The First Key Linkage: From Micro-Demand-Supply to Macro-Aggregate Demand-
Aggregate Supply
The consumers’ demand (D) and firms’ supply (S) at individual level as well as aggregate demand (AD) and
aggregate supply (AS) at national level are basic micro-macro-relations in economics. From micro-demand (D) -
supply (S) model to macro-aggregate demand (AD) - aggregate supply (AS) model, the form is very similar, i.e.
demand curve is a downward-sloping curve and supply curve is upward-sloping one, as shown in Figure 3, which
gives strongly sign to unify micro-economics and macro-economics.

Fig-3. A Descriptive Micro-Macro-relation
The above figure suggests us that micro- D-S system can be integrated to become aggregate macro- AD – AS
system, while macro- AD-AS system can also reduce to discrete micro D-S system. With using logarithms of the real
output Y, nominal money M, nominal prices P and nominal wages W, the aggregate demand – aggregate supply
framework can be expressed as
( ), 0
( ), 0
a M P a
Y
b M W b
(4)
When nominal wages are fixed at level W*, the above framework plus W=W* constructs Keynesian general
theory, where the increment in M will increase both output Y and the price level P. However, the linkages of discrete
and aggregate processes need other two keys, namely marginal effect and multiplier model.
4.2. The Second Key Linkage: Marginal Effects in Both Micro- and Macro-Economies
The utility-maximizing consumers and the profit-maximizing firms are considered to be important rules in
economics, which can be expressed by marginal effect, as follows (Samuelson and Nordhaus, 2005).2
(1) The ratios of marginal utilities of goods for all consumers are equal to the relative prices of those goods.
(2) The ratios of marginal costs of goods produced by firms are equal to the relative prices of those goods.
(3) The relative marginal revenue products of all inputs are equal for all firms and all goods and are equal to
those inputs’ relative prices.
In mathematical analysis of general equilibrium (Samuelson and Nordhaus, 2005), the conditions for
competitive general equilibrium are classified into two categories: consumer equilibrium and producer equilibrium.
In consumer equilibrium, the ratio of the marginal utilities of two goods (MU1/MU2) is equal to the ratio of their
prices (P1/P2). In producer equilibrium, the ratio of the marginal costs of two final products (MC1/MC2) is equal to
the ratio of their prices (P1/P2). Therefore, in the market, when final products become goods, combing consumer
equilibrium and producer equilibrium, the general equilibrium means

(5)
The Eq. (5) reveals that one of the essences of general equilibrium or Arrow-Debreu mode focuses on marginal
effect of goods.
On the other hand, macroeconomics marks that the marginal propensity to consumption (MPC) and marginal
propensity to save (MPS) related like mirror images, i.e.
1 MPSMPC (6)
The Eq. (6) reveals one of characteristics of national consumption behaviors, and the 1/MPS=1/(1-MPC) is
just the expenditure multiplier or investment multiplier.
4.3. The Third Key Linkage: AD–AS Model can be Approached by Multiplier Model
The existence of a multiplier effect was initially proposed by Keynes’ student Richard Kahn in 1930s. Although
some scholars reject or downplay the importance of multiplier effects, particularly in terms of the long run, the
multiplier model has been used as an argument for the efficacy of government spending or taxation relief to
stimulate aggregate demand.
A multiplier is a factor of proportionality that measures how much an endogenous variable changes in response
to a change in some exogenous variable in macroeconomics. Including both money multipliers and fiscal multipliers,
2
Cf.: Samuelson, P.A. and W. D. Nordhaus. 2005, Economics (18th ed.). McGraw-Hill Co., Chapter 14 Appendix
6. International Journal of Economics and Financial Research
164
multiplier model causes macroeconomic effects. While a fiscal multiplier is a ratio of a change in national income to
the change in government spending, it causes that a money multiplier is one of various closely related ratios of
commercial bank money to central bank money under a fractional-reserve banking system. More generally, the
exogenous spending multiplier is the ratio of a change in national income to any autonomous change in spending
(including private investment spending, consumer spending, government spending, or spending by foreigners on the
country's exports). A money multiplier measures the maximum amount of commercial bank money that can be
created by a given unit of central bank money. That is to say, in a fractional-reserve banking system, the total
amount of loans that commercial banks allowed to extend (i.e. the commercial bank money that they can legally
create) is a multiple of reserves; this multiple is the reciprocal of the reserve ratio, and it is an economic multiplier.
One of the main assumptions in the multiplier analysis is that prices and wages are fixed in the short run.
Although this is an oversimplification (as many prices adjust quickly in the real world), this assumption captures the
point that some of the adjustments to AD shifts will come through output adjustments if some wages and prices are
sticky. So, Keynesian economists calculate multipliers that measure the effect on aggregate demand (AD) only.
Then, American Economist Alvin Hansen and Paul Samuelson extended it to get the multiplier-accelerator model,
i.e. Hansen-Samuelson model.
As multiplier model can approach AD–AS model (c.f. (Samuelson and Nordhaus, 2005), we can combine
marginal effect with multiplier model then penetrate demand and supply for unification. Thus, we can find a unified
model via three keys to link micro- and macro-economics, in which demand and supply, marginal effect and
multiplier model are interrelated to each other.
While Arrow-Debreu model describes general micro-economic equilibrium, Mundell-Fleming model expresses
general macro-economic one. There are three keys to link A-D model and M-F model together: (1) Demand-supply
relation, which penetrates micro- and macro-economy with similar pattern; (2) marginal effect, which reveals same
principles in micro- and macro-economy and constructs expenditure multiplier or investment multiplier; and (3)
multiplier model, which approaches to AD-AS. As aggregate demand (AD) – aggregate supply (AS) is approached
by multiplier model and linkage of expenditure multiplier or investment multiplier to marginal effects, it is revealed
that micro-Arrow-Debreu model can be combined with macro-Mundell-Fleming model. Indeed, a macro-economic
model is much more complicated than micro-economic one, because there are complex money interactions, as well
as global interest rates and exchange rates. Fortunately, demand-supply relation, marginal effect and multiplier
model become key bridges across them. Thus, we can understand unified micro-macro-economics. For the unified
understanding, it is suggested that the Arrow-Debreu-Mundell-Fleming model become standard economic model,
which is characterized by a geometrical analytical system constructed by AD-AS-IS-LM curves. Then plus Laffer
curve, the unified synthesized model completed, which could promote economic analysis.
5. Policy Analysis Towards Economic Efficiency Via Interest and Exchange
Rates
In policy analysis, traditionally, macroeconomic policy is usually implemented through two sets of tools:
monetary policy and fiscal policy. Both forms of the policy are used to stabilize the economy, which usually means
boosting the economy to the level consistent with economic resources.
On monetary policy, central banks implement the policy by controlling the money supply through several
mechanisms. Typically, central banks take action by issuing money to buy bonds (or other assets), which boosts the
supply of money and lowers interest rates, called expansionary money policy; or in the case of contractionary
monetary policy, banks sell bonds and take money out of circulation. Also, bank can continuously shift the money
supply to maintain a fixed interest rate target. Some banks allow the interest rate to fluctuate and focus on targeting
inflation rates instead. Central banks generally try to achieve high output without letting loose monetary policy to
create large amounts of inflation.
On the other hand, fiscal policy is the use of government revenue and expenditure as instruments to influence
the economy, including tools such as expenditure, taxes, and debt. However, the effects of fiscal policy may be
limited by crowding out. When government adopts spending projects, it limits the amount of resources available for
private sectors to use. Crowding out occurs when government spending simply replaces private sectors output
instead of adding additional output to the economy. Crowding out also occurs when government spending raises
interest rates with restricting investment. Defenders of fiscal stimulus argue that crowding out is not a concern when
the economy is depressed, plenty of resources are left idle, and interest rates are low.
When the economy is producing less than potential output, government spending can be used to employ idle
resources and boost output. Although government spending does not have to make up for the entire output gap, the
multiplier effect could boost the impact of government spending.
However, the effects of fiscal policy may be limited by crowding out. When government takes on spending
projects, it limits the amount of resources available for the private sector to use. Crowding out occurs when
government spending simply replaces private sector output instead of adding additional output to the economy.
Crowding out also occurs when government spending raises interest rates with restricting investment. Defenders of
fiscal stimulus argue that crowding out is not a concern when the economy is depressed, plenty of resources are left
idle, and interest rates are low.
Fiscal policy is also implemented through automatic stabilizers. Without suffering from the policy lags of
discretionary fiscal policy, automatic stabilizers use conventional fiscal mechanisms but take effect as soon as the
7. International Journal of Economics and Financial Research
165
economy takes a downturn: spending on unemployment benefits automatically increases when unemployment rises
and, in a progressive income tax system, the effective tax rate automatically falls when incomes decline.
Economists usually favor monetary over fiscal policy because it has two major advantages. First, monetary
policy is generally implemented by independent central banks instead of the political institutions that control fiscal
policy, where independent central banks are less likely to make decisions based on political motives. Second,
monetary policy suffers shorter inside lags and outside lags than fiscal policy does, as central banks can quickly
make and implement decisions while discretionary fiscal policy may take time to pass and even longer to carry out.
Yet, actually, the economic effects of monetary or fiscal policy could be restricted, as the changes of three ratios
will affect each other. With integrating analytical framework of interest, exchange, tax rates in above synthetic
model, the situation is clear as a case of raising interest rate (by bank) as shown in Figure 4.
Fig-4. Policy analysis in the case of changing interest rate with implying exchange rate change
The policy of raising interest rate could cause feedback chain: γ↑→MS↓→Y↑, which is equivalent to tax
cuts as γ↑ → τ↓, as it is same to τ↓→ γ↑ → MS↓, which means that the policy effect of raising interest rate is
equivalent to that of tax cut, or, the policy effect of tax cuts is equivalent to the raising interest rate, leading to less
money supply. Inversely, increasing money supply is equivalent to lower interest rate or lifting tax, i.e. MS↑→ γ↓
→τ↑. However, once money supply increases, the inflation could occur, resulting in offseting the policy effect. Thus,
the policy tools are limited by the correlated links, where any rate impacts each other, leading to restricted economic
effects.
Since the exchange rate relates to interest rate according to Eq. (1), the change of interest rate implies the change
of exchange rate at same time. Therefore, the modification of exchange rate resembles relative effects of interest
rate. Especially, if the exchange and interest rates change at same directions (π↑ → γ↑, π↓→ γ↓), the effects of
changing exchange rate will similar with the effects of changing interest rate. However, if the exchange and interest
rates change at different directions (π↑ → γ↓, π↓→ γ↑), complex situations will happen. The exchange rate is also a
relatively independent variable, and it affects and is affected by international economy. When we need to simulate
national local market, we can raise the exchange rate. Otherwise, when we need to promote international global
trade, we may lower the exchange rate.
6. Policy Analysis Towards Social Equality Via Taxation
Generally, tax is dominated by government, which is rigidly restricted by laws. For social equity, it is better to
set high tax rate for charging rich people and low tax rate to protect poor persons. Interest rate can be changed by
central bank, referring to economic level and situation. And exchange rate seems random changeable following
international money market, though some nations could also do impacts on its changes.
Politically, tax, interest, and exchange rates serve for national objects, so that a national government cannot
abandon the domination of tax rate, interest rate, and exchange rate. In a national view, interest rate focuses on
money efficiency, which could optimizes the money market and the liquidity. Exchange rate also expresses national
finance policy, which could regulate international trade and is determined by international financial market. The tax
rate marks national policy for the redistribution of social wealth, which pursues social equality. The interest rate can
be changed by the central bank, referring to economic level and situation. The exchange rate is randomly changeable
following international money market, though some nations could also exert impacts on its changes.

Using the above synthetic model integrating interest, exchange and tax rates, when economy overheats or
expands (Y↑↑), a policy analysis for the tax reduction and the tax increase is shown in Figure 5.
Fig-5. A policy analysis for the tax reduction and the tax increase during economic overheat
The policy of Figure 5 implies that the tax reduction should be good if tax rate is lower than normal (τ < τ0) and
tax increase should be good if tax rate is higher than normal (τ > τ0), during the period of economic overheat or
expansion (Y↑↑), which would benefit following items.
(1) At national level, decreasing official corruption (Y↑↑caused B -> B’, policy τ2 -> τ1 would lead to IS’ ->
IS, or via LM’ -> LM and B’’ -> B for reaching optimal equilibrium A-B-C).
(2) At enterprise level, increasing R&D input (Y↑↑caused A -> A’, policy τ2 -> τ1 would lead to MS’->MS,
or via MD’ ->MD and A’’->A for reaching optimal equilibrium A-B-C).
(3) At individual level, stimulating consumption and charitable donation (Policy τ2 -> τ1 would lead to MS’-
>MS or MD’->MD for reaching optimal equilibrium A-B-C).
On the other hand, when economy depresses or contracts (Y↓↓), a policy analysis for the tax reduction and
the tax increase is shown in Figure 6.
Fig-6. A policy analysis for the tax reduction and the tax increase during economic depression
The policy of Figure 6 implies that the tax reduction should be good if tax rate is higher than normal (τ > τ0) and
tax increase should be good if tax rate is lower than normal (τ < τ0), during the period of economic depression or
contraction (Y↓↓), which would benefit following items.
9. International Journal of Economics and Financial Research
167
(1) At national level, balancing the rich and the poor (Y↓↓ caused B’ -> B, and then policy τ1 -> τ2 would lead
to IS -> IS’, or via LM -> LM’ and B’’ -> B’ for reaching optimal equilibrium A’-B’-C’).
(2) At enterprise level, decreasing bank loan (Y↓↓ caused A’ -> A, and then policy τ1 -> τ2 would lead to MS-
>MS’, or via MD ->MD’ and A’’->A’ for reaching optimal equilibrium A’-B’-C’).
(3) At individual level, reducing consumption, particularly deleting luxury ( Policy τ1 -> τ2 would lead to MS-
>MS’ or MD->MD’ for reaching optimal equilibrium A’-B’-C’).
In both Figure 5 and Figure 6, the normal point of tax rate (τ0) can be defined as legal point in tax laws, or
theoretical expected point.
Certainly, the tax policy look complicated, more than monetary policy, where the interest ratio is an effective
tool for regulating economy by raising or reducing interest rates. However, the tax policy may be useful tool for
balancing social wealth, particularly combining efficiency and equality. A good tax policy could reach axiological
good. In considerations of political economics, the tax reduction on enterprises could benefit all enterprises, while
the tax increase on rich persons could benefit poor people.
Totally, the tax rate, interest rate, and exchange rate really represent different views of political economics. The
tax rate marks national policy for the redistribution of social wealth, which expresses social equality. The interest
rate describes national financial policy, which is a way to optimize national financial market. The exchange rate
characterizes the interactions of international economies, which is determined by international trade and international
financial market.
7. Discussion Wealth Distribution and More
There are two economic issues concerned by economic analysis towards the social good: 1) How to distribute
social wealth between rich agents and poor ones, as well as nations and enterprises? 2) How to maintain social
justice combining efficiency and equality?
In political economics, wealth distribution and capital profit are always important issues for discussion, in which
the former concerns social equality and the latter represents economic efficiency. In some cases, if we pay attention
to social equality of wealth redistribution, we might lose partly economic efficiency. For maintaining high economic
efficiency, we might lose partly social equality. Economic policy actually resembles an art for balancing efficiency
and equality, where the social wealth redistribution (regulation via tax rate) and economic efficiency (realization via
interest rate) become important factors for applications.
In any societies, there are always rich and poor people. The governments get tax revenues to support public
affairs and to regulate rich-poor difference, for realizing social equality via wealth redistribution. Both social and
personal surplus money would cumulatively transfer to capital, and the capital demands effective reciprocation via
interest or investment. More issues on the capital and wealth distribution have been discussed by Piketty’s analysis
(Piketty et al., 2014).
Taxation is not only a technical matter, but also preeminently a political and philosophical issue, perhaps the
most important political economic issue. Without taxes, society has no common destiny, and collective action is
impossible. It is certainly correct that progressive taxation plays a key role in wealth redistribution. A progressive tax
is a crucial component for social equality, which plays a central role in its development and in the transformation of
the structure of inequality in the world, and remains important for ensuring the viability of social equality in the
future.
Generally, tax, which is dominated by government and rigidly restricted by laws, is the key element to answer
these questions. For social equity, it is better to set high tax rate for charging rich agents and low tax rate to protect
poor ones. In a country with taxation ~ 1 billion dollars, if tax rates changes 1%, more than million dollars taxation
will be changed. Given that consumption and investment expenditure together account for a large percentage (about
80%) of GNP in major nations (Abel, 2000), taxation is a political economic consideration for approaching the
axiological good to adjust rich and poor via tax. If we consider more factors, including wages, inflation,
employment, welfare and so on Lucas and Rapping (1970), Phelps (1967), we will meet a very complicated
economic system, in which the taxation also keeps an important factor.
Also, the tax rate may be affected by interest rate. In Figure 3 and Figure 4, all policies of tax regulations are
equivalent to reducing interest (γ2 -> γ1) when economy overheats or expands (Y↑↑), and all policies of tax
regulations are equivalent to increasing interest (γ1-> γ2) when economy depresses or contracts (Y↓↓). Therefore,
it is better to keep reducing interest during economy expansion and keep increasing interest during economy
depression.
Above analysis gave a trustable reference. The economic analytical methods focus on geometric analysis,
yielding tendency estimation, rather than complete exact computation.
8. Conclusion
The interest, exchange and tax rates are three important control factors in both macroeconomic and
microeconomic systems, where interest, exchange and tax rates interact with each other. Tax expresses the economic
policy of governance, which reflects social equality. Interest rate is a key parameter for regulating money supply,
which determines the national finance with reflecting economic efficiency. Exchange rate is a vital factor for
international business, which determines the international economy.
We know that tax rate had long-term stability regulated by laws, while interest rates had short-term stability
controlled by banks and the exchange rate changed randomly following market’s change. As tax rate regulates

wealth redistribution for approaching social equality, interest policy represents national finance policy for optimizing
economic efficiency, and exchange rate describes international economic policy for realizing national benefits, the
three ratios possess key role in regulating national demands. We should pay more attention to modify the three ratios
under the synthesized framework for balancing economic efficiency and social equality.
As the results, it is suggested to utilize modified strategies via exchange and tax rates besides normal monetary
and fiscal policies mainly via interest and tax rates. When ones need to simulate national local market, ones can raise
the exchange rate. Otherwise, when ones need to promote international global trade, ones may lower the exchange
rate. Meantime, it is found that tax reduction is good policy when tax rate is lower than normal, and that tax increase
is good social policy when tax rate is higher than normal, during economic overheat. Also, tax reduction is good
policy when tax rate is higher than normal and that tax increase is good social policy when tax rate is lower than
normal, during economic depression. While economic system seeks efficiency and social system pursues equality,
common interest modifications with elastic exchange and tax rates can be applied for balancing efficiency and
equality, which will benefit economic social development towards epistemological true with axiological good.
