This document provides an introduction, literature review, model specification, data description, empirical results, and conclusions regarding a study analyzing the effect of economic conditions on Greek net migration from 1991-2014. The study uses econometric techniques to model the relationship between key economic indicators like GDP, inflation, unemployment, interest rates, and dummy variables for economic crisis and EU membership, on net migration. The initial linear model showed some issues which were partially addressed by transforming it to a log-log model. Overall, the study found GDP and unemployment were statistically significant in explaining migration, and concluded that strengthening Greece's economic position could help stabilize net migration flows.

Based on the data of Japanese Prime metropolitan area from 1955 to 2013, this paper studies the effect of industry agglomeration and population aggregation on economic growth in Tokyo metropolitan area. Through the processing of the panel data, we find that the industry agglomeration in Japanese Prime metropolitan region has apparently positive impacts on its economic growth, and also, population aggregation can positively effects its economic growth. Following this paper is try to carry out research on Tokyo —the core city of Japanese Prime metropolitan area, to study the influence of industry agglomeration on its economic growth. This paper thinks that in the process of the development of the city group, due to resource constraints, the manufacturing output unit of land demand big industry will gradually from the degree of economic development is relatively high in the whole city and the city to evacuate, inside, labor resources are gradually to the regional flow of high GDP per capita output.
In this paper, we analyze the demographic and economic consequences of endogenous migrations flows over the coming decades in a multi-regions overlapping generations general equilibrium model (INGENUE 2) in which the world is divided in ten regions. Our analysis offers a global perspective on the consequences of international migration flows. The value-added of the INGENUE 2 model is that it enables us to analyze the effects of international migration on both the destination and the origin regions. A further innovation of our analysis is that international migration is treated as endogenous.
In a first step, we estimate the determinants of migration in an econometric model. We show, in particular, that the income differential is one of the key variables explaining migration flows. In a second step, we endogenize migration flows in the INGENUE 2 model. In order to do so, we use the econometrically estimated relationships between demographic and income developments in the INGENUE model, which enables us to project long-run migration flows and to improve on projections of purely demographic models.

Government expenditure is a very instrumental demand tool in achieving economic stability and policy makers frequently use it to influence certain economic outcomes. Government expenditure majorly consists of two components: investment and consumption components. Many researchers concede that higher level of government consumption expenditure is growth retarding and therefore undesirable. The aim of this paper was to establish the economic determinants of government consumption expenditure in Kenya. The results showed that in the long-run, while 1USD increase in GDP causes USD1.3 increase in government consumption expenditure, a unit increase in inflation rate would cause USD1.8 increase in consumption expenditure. However, 1USD increase in foreign direct investment and external debt stock causes, respectively, USD 0.07 and USD 2.6 drop in government consumption expenditure. Corruption, democracy and political instability have positive effects on government consumption expenditure in Kenya. Urbanization and population dynamics jointly affect the variable in the short-run. This paper recommends that the government should strengthen its institutions that are mandated to deal with graft cases, create peaceful political setting at all times and ensure a friendly environment to foreign investors.

In this paper, we assess the demographic and economic consequences of migrations in Europe and neighbourhood countries. In order to do so, we rely on a multi-region world overlapping generations model (INGENUE2). The rich modeling framework of this multi-regions model allows us to put into connection migration with the "triangular" relationship between population aging, pension reforms and international capital markets. With this model, we are also able to quantify the demographic and economic consequences of migration ows on both the regions receiving and losing migrants. Our analysis is based on a very detailed migration scenario between Western Europe and the Neighborhood regions constructed by taking into account both the current situation and some prospective empirical scenarios. Our quantitative results shed some light on the long term consequences of migration on regions that are not at the same stage in the ageing process. Concerning the regions receiving migrants, despite some improvement of their public pension system, it appears that our realistic migration scenario does not offset the effect of ageing in these regions, leaving room for pension reforms. Concerning the regions losing migrants, the adverse economic consequences of emigration appear to be all the more important than the region is advanced in the ageing process (and is already suffering from a declining population).

Remittance inflow and economic growth the case of georgiaAzer Dilanchiev
Abstract:
Remittance inflow become one of the main source of capital flows in the world. It is noted that remittance is
very effective in promoting household welfare and as an alternative source of capital inflow. However in it
uncertain whether or not it leads to economic growth. This article examines the effects of remittances inflow
on economic growth in Georgian republic. The impact of remittance inflow on GDP growth was analyzed and
tested by Unit Root Test, Johansen Co-integration and VAR Granger Causality/Block Exogeneity Wald Tests.
In the paper the quarterly data interval from the first quarter of 1999 to third quarter of 2015 was used. As a
result it was found out that that there is a nexus between remittance and GDP and it is concluded that
remittance leads to increase in GDP growth.

Abstract
Prompting this analysis was the International Monetary Fund’s 2010 report of gross domestic product purchase power parity per capita, where the Democratic Republic of the Congo (D.R. Congo) ranked last, at a meager $328 (U.S.) annually. With the recent debates concerning whether or not sub-Saharan African countries have benefited from capital inflows, this paper explores the effects of foreign direct investment and foreign aid on the D.R. Congo’s gross domestic product. In the D.R. Congo, empirical evidence suggests that a slight positive correlation exists between capital inflows and gross domestic product. However, due to the volatility of foreign direct investment and aid, comprehensive policies promoting economic and political stability should be examined.
The Effects of Foreign Direct Investment and Foreign Aid On Gross Domestic Product in Developing Countries: A Case for the Democratic Republic of the Congo
The history of the effectiveness of capital inflows to Africa has raised much debate as to whether or not any contributions have increased development. The literature overviews of the area, particularly in regards to sub-Saharan Africa (SSA), have identified many determinant variables of growth. Highlighting several forms such as foreign direct investment (FDI), official development assistance (ODA), domestic savings, improved infrastructure, debt relief, and reinvestment, among others, many economists conclude that the first two are most important for increasing economic growth. It is FDI and foreign aid (AID), both external sources, which benefit economic expansion in less developed countries (LDCs). This phenomenon, despite not always being true, has gained recent momentum. According to Collier and Gunning (1999) their study for the period between 1960-1989 found one explanatory variable, investment to GDP ratio, statistically significant in explaining growth in Africa. They concluded that African countries with higher investment to GDP ratios had higher economic growth rates. Another study, Loots (2003) found similar results. The study, covering the period from 1995-2000, found that per-capita growth during the period was directly related to external capital inflows. In particular, Loots (2003) noted that FDI and ODA flows were important in understanding the growth of African countries in the mid to late 90s.

Pension systems and reforms are critically influenced by demographic developments that are increasingly compared across countries to identify common issues and trends. For demographic projections researchers across the world rely on those produced by the United Nations; for Europe the demographic projections by Eurostat form the basis of the periodic aging report by the EU Commission. While these projections are technically well done the underlying assumptions for the demographic drivers – fertility, mortality and migration – in the central variants are limited and are largely flawed. Worse, they risk offering a wrong picture about the likely future developments and the relevant alternatives. This paper investigates the assumptions of the demographic drivers by UN and Eurostat, compares it with those by national projections in Portugal and Spain, and offers a review of alternative, recent and cutting edge approaches to project demographic drivers that go beyond the use of past demographic developments. They suggest that economic and other socio-economic developments have a main bearing on future trends in fertility, mortality and migration. And they support the assessment that the UN/Eurostat projected re-increase in fertility rates may not take place, that the increase in life expectancy may be much larger, that the future flows of net migrants to EU countries may be much higher and rising. The resulting overall underestimation of population aging has a bearing on the financial sustainability of the pension systems and reform choices, a topic to be explored in the next papers.
Many economists have confirmed the negative and direct relationship between economic growth and income inequality. Recent studies have tried to analyse the different transmission channels through which inequality may affect economic performance indirectly. In this paper, we are only referring to the education channels: public and private education expenditures and human capital, in order to evaluate the role of each in the explanation of this negative correlation. We noticed that a high level of inequality requires more public resources this may impede economic growth. Income inequality also discourages private financing in education and human capital accumulation which leads to a sluggish economic growth. These findings imply that private education expenditure is the most important channel which explains this negative relationship reported in the literature.
Everything you need to know about the Corona virus transformation from stage 1 to killing stage and overall overview of Corona virus Average daily cases from all over the world you and global economic crisis
Monetary policy is an important public policy, but it is not the only one to stabilize our economy and reduce its business cycles. The leading central bank, the Federal Reserve of the U.S., has introduced, after the 2008 global financial crisis, new instruments and unusual facilities to implement its new innovative monetary policy. The financial world and mostly the social scientists watch as the Federal Open Market Committee (FOMC) decides on a target interest rate in the federal funds market for the next period. The framework that the FOMC uses to implement monetary policy has changed over the last twelve years and continues to evolve today. Here, we try to evaluate the new instruments and their “effectiveness”. Before the 2008 financial crisis, policymakers used one set of traditional instruments (tools) to achieve the target rate. However, several policy interventions, introduced soon after the crisis, drastically altered the landscape of the federal funds market and the traditional economic theory. This new and uncertain environment, with enormous reserves and even interest on reserves, necessitated a new set of instruments by the Fed for its monetary policy implementation. Lately, after seven years of zero interest rate, the FOMC began in December 2015 to increase the target rate and then, went back again to a lower one, but many questions arise. How did they evaluate the effectiveness of these new instruments? Is the current federal funds rate the appropriate one for our economic wellbeing? How efficient was so far this ZIR monetary policy after the latest global financial crisis? Why the Fed put all these burdens of its ‘innovated” new monetary policy to the poor taxpayers (bail out) and to the risk-averse depositors (bail in)? Is it possible for the Fed’s policy to prevent the future financial crises? The federal funds rate was very low and affected negatively the financial markets (bubbles were growing), the real rates of interest (it is negative for twelve years), and the deposit rates (they are closed to zero for twelve years). The redistribution of wealth of depositors and taxpayers continues, which means the true economic welfare is falling and a new global recession was in preparation, if the current unfair easy money policy will persist, ignoring the necessity of a prevention of financial crises. Then, it came as an unexpected plague the coronavirus pandemic, following with a new but, the worse in economic history global crisis (chaos).
Can Changes in Age Structure have an impact on the Inflation Rate?The Case o...WilliamTWang1
Demographics in different parts of the world are facing an aging population and a diminishing growth in population, particularly high-income countries. This paper estimates the relationship between the growth of age composition and the inflation rate while including other macroeconomic variables as explanatory variables to ensure the model has a good fit to the true model. This paper estimates the case in the United States of America from 1960 to 2016, studying the relationship between the inflation rate and the growth rate of the proportion in different age cohorts. The results show a consistent and significant relationship between the growth in the proportion of different age cohort and inflation rate,
in which the increase in the proportion of net savers (age between 30 – 64 years old) and retirees
(age between 65 and above) in the economy encourages higher inflation rate. This can be explained by the Life Cycle Hypothesis combined with other economic theories. In any case, the results suggest that demographic has an association with the inflation rate in which the projection of age composition in the future can be used as a tool to better forecast the inflation rate. This could open the possibility for monetary authorities to better implement monetary policy to sustain their mandate.

Abstract
Each day, all over the world, individuals, couples and families make the excruciating decision
to gather their things and begin a new life in another country. Each situation is different to the
next, and each is motivated by different forces. Some are motivated by the prospects of a safe
lifestyle, fleeing their home due to war and destruction. Others are motivated by local
economic conditions, fleeing the stranglehold of unemployment for the chance to start over.
It is these economic migrants who are the focus of this paper. By using a series of
econometric techniques the paper attempts to show the relationship between a pool of key
economic data points and net migration for Greece, a nation that has experienced some of the
worst economic conditions post the Global Financial crisis. It will be using data from 1991 to
2014 to draw meaningful conclusions.

Introduction
In the last decade the global economy has seen fundamental changes. From a period
of high growth during the first part of the 21st century (Dicken, 2013) to an catastrophic
global recession instigated by the Global Financial Crisis of 2008. Through these sweeping
changes saw a wave of economic refugees in search of a more stable and prosperous life.
Economic refugees are people whose long term prospects have been negatively impacted by
local economic performance and not necessarily by other factors like war or political unrest.
However it is possible that these external issues ultimately lead to economic problems.
Greece has been the most high profile country to feel the effects of the recent global
economic turmoil with growing debts totalling 175.1% of GDP in 2013 (Eurostat, 2013). As
a result of this, it is perfectly suited to studying the effects of economic performance on net
migration. The term net migration during this research is defined as total inflows minus out
flows (World Bank, 2014). It is expected that poor economic performance of a nation should
be reflected in the number of economic refugees that leave that particular nation. Though this
analysis, policies can be reviewed and adjusted as necessary to help mitigate an unsustainable
flow of migrants which will further impact their country of origin as they lose skilled workers
but also places unnecessary pressure on neighbouring nations.

Review of previous literature
To form the basis of this research paper, previous research was reviewed and the best
parts analysed and drawn upon. In addition to this, common issues were discovered and
compared. These issues tended to revolve around lack of empirical data points. In relation to
Greece some data is released semi-annually. This issue is seen in other nation’s economic
data. As an example, Romania, an ex-communist country has a lack of historic data sets
which makes drawing meaningful accurate conclusions difficult. (Rembar, 2015).
During her 2012 study of internal migration Daniella Bunea (2012), used panel data
from 2004-2008 (NUTS 3 level) from a dynamic point of view. This small sample size is
down to a sheer lack of data. Using real GDP per capita, nominal employment and
unemployment rate, degree of urbanisation, population density she attempted to model the
effects these had on internal migration. By taking some of these same variables we hope to
expand show how these changes effect migration out of Greece.
Martinho (2011) analysed the migration mobility in Portugal focusing on the
movements of the labour market. He used the cross section data to analyse the evolution of
migration from the availability of housing point of view. Also he tested the covariance of
migration between the costal and the continental region of Portugal.
Basile, Girardi and Mantuano (2010) used longitudinal data for 103 Italian regions
over the 1995-2007 to measure the dynamic of the unemployment rate. Their research
showed the negative impact of migration over unemployment rates. From this it can be
deduced that the rate of unemployment has a compounding effect on other economic
indicators. As such, it forms an important part of the economic model.
5. Page 5
Specification of the Model
Drawing from the conclusions of previous research it is clear that some economic
variables form the key to qualifying economic effects on migration.
The most common being the Gross Domestic Product (GDP) of the nation in question.
Real GDP (Which takes inflation into account over time) is a basic look at the overall
performance of an economy. The Consumer Price Index (CPI) or inflation shows how the
cost of living increases or falls over a period of time. As the inflation rate grows year on year
it makes it more difficult for the population to go about their day to day lives if inflation is
not met with a wage increase as well. Interest rates set by the central bank effect how
expensive it is for companies to borrow money in order to invest in new technology or
upgrade their capital to make their business more productive. The overall unemployment rate
of Greece is also a necessary variable when assessing migration. A high unemployment rate,
effects government debt as their social security burdens increase. It also increases the pool of
people who consider migrating to another part of the world. Penultimately, Greece’s highly
publicised economic crisis in the early 2010s would have contributed greatly to an outflow of
population, as they were trying to escape financial and economic ruin. We have included this
as a dummy variable, which will take the form of 1 during the years when the economic crisis
was occurring. Finally, the effect that the European Union has had on the Greek economy
cannot be under stated. Using a dichotomous or dummy variable for data taken when Greece
was both in and out of the Eurozone will highlight the effects, if any that this has had overall.
In addition to this a random variable is added to take into account any external factors that
will affect the results but are not quantified by the variables.
As such, the model follows a linear function of:
𝑌( 𝑚𝑖𝑔𝑟𝑎𝑡𝑖𝑜𝑛)
= 𝛽1 + 𝛽2( 𝐺𝐷𝑃) + 𝛽3( 𝐼𝑛𝑓𝑙𝑎𝑡𝑖𝑜𝑛) + 𝛽3( 𝑈𝑛𝑒𝑚𝑝𝑙𝑜𝑦𝑚𝑒𝑛𝑡)
+ 𝛽4( 𝐼𝑛𝑡𝑒𝑟𝑒𝑠𝑡 𝑅𝑎𝑡𝑒) + 𝛿( 𝐸𝑐𝑜𝑛𝑜𝑚𝑖𝑐 𝑐𝑟𝑖𝑠𝑖𝑠) + 𝛿( 𝐸𝑈) + 𝑒
These key economic indicators will model their ultimate effects –positively and
negatively - on net migration.

Data Description
For the purposes of this paper, all data points were taken from reputable data sources
all over the world. For Greece, most of the data required was available through government
data agencies. Eurostat is the European body tasked with sourcing and keeping key statistical
information about all its member nations. Statistics on Gross Domestic Product and
Unemployment and inflation were all sourced from this government agency. In addition to
Eurostat, Trading Economics, a data sourcing website provided data on migration rates as
well as interest rates that were in effect in Greece through the time period in question.
In the case of real GDP this data takes the form of United States dollars. This is to
remain consistent with other global statistics. Inflation, unemployment and interest rates are
noted in percentage points. Finally the explanatory variable refers to before and after Greece
joined the European Union. This is noted by a 0 for no and a 1 for yes.
Some weaknesses in the data that has been sourced are in relation to the frequency of
the data points being updated. This was most prevalent with migration data, where, in recent
times, new data sets are only updated every four to five years, which is in line with other
European nations. As such, the points of data that fall in between may be estimates with an
error built into the statistic. The remove this, it would require government agencies to
conduct more thorough analysis more frequently.
All data used in this model was time-series.

Empirical Results
Upon regressing the model, many new details came to light about it. It was worth
noting the R2 for the model as 0.8137, meaning that 81.37% of variation in the dependent
variable (migration) was explained by the independent variables in the model. This is a
relatively good outcome for a first-stage model.
Coefficients were predicted for each variable, with the negative signs being expected
for inflation, unemployment, and interest. This means that for a one-unit increase in any of
these variables, there would be a further outflow of people. The nature of these variables
makes this a predictable and likely conclusion. However, there was a surprising negative sign
for the GDP coefficient, meaning that as GDP increases more people would want to leave.
This does not seem likely in reality. The positive coefficient for the economic crisis dummy
variable was also unexpected, as it would be more likely that people would want to leave
Greece when faced with economic downfall. The negative coefficient for the other dummy
variable of joining the Eurozone could be considered either likely or unlikely as the decision
to leave Greece due to this factor would be very much based on personal preference of each
citizen.
We were able to assess the errors of the regression for normality and
heteroscedasticity. Through use of the Jarque-Bera test, it became apparent that the errors
were not normal due to high values for skewness and kurtosis. The White test was then used
to determine that the errors did indeed have a constant variance, making them homoscedastic
– a desirable outcome.
Using the p-value test for individual significance, we were able to ascertain that the
variables GDP and unemployment were statistically significant at 5%, while the other four
variables were not. At 1%, only GDP remained significant. The significant variables in the
model had some power in explaining the outcome of migration (the dependent variable).
Although this result was rather disappointing, use of the F-test for overall significance
implied that the model as a whole was significant, meaning that the combination of variables
was successful at explaining at least part of the dependent variable.
We conducted assessments for correlation of both the errors and the variables. The
Durbin-Watson test was used to test for a relationship between the errors, with the d-statistic
landing in the no decision zone between dupper and dlower. This meant that we could not be sure
whether or not there is any positive autocorrelation. The Breusch-Godfrey test was used to
examine the presence of serial correlation between the variables at 3 lags. This resulted in the
conclusion that there was no serial correlation at any of the lags for this model.
The Ramsey RESET test was used to check that the correct functional form was used,
and that there were no omitted variables. At 5%, we had to reject H0, meaning that the model
either had incorrect functional form or was missing explanatory variables. This was an issue
as the model would not have been providing a good or reliable description of the
circumstances, and was not the best it could be.
The final test conducted on the model was the variance inflation factor (VIF) test for
multi-collinearity. We determined that there was an issue with multi-collinearity for the
8. Page 8
variables GDP and inflation, meaning that these were more highly correlated with other
explanatory variables than with the dependant variable. This can cause large variance in the
OLS estimators, and an abnormally high R2 and F-stat. It can also result in the individual
significance of these variables being quite low. None of the other variables had this
characteristic.
To try and remedy the problems in model 1 of incorrect functional form/omitted
variables and multi-collinearity, we attempted to transform the model from linear to log-log
the only difference being that migration and GDP were taking their log forms. Model 2 can
be transcribed as:
𝑙𝑛𝑌( 𝑚𝑖𝑔𝑟𝑎𝑡𝑖𝑜𝑛)
= 𝛽1 + 𝛽2( 𝑙𝑛𝐺𝐷𝑃) + 𝛽3( 𝐼𝑛𝑓𝑙𝑎𝑡𝑖𝑜𝑛) + 𝛽3( 𝑈𝑛𝑒𝑚𝑝𝑙𝑜𝑦𝑚𝑒𝑛𝑡)
+ 𝛽4( 𝐼𝑛𝑡𝑒𝑟𝑒𝑠𝑡 𝑅𝑎𝑡𝑒) + 𝛿( 𝐸𝑐𝑜𝑛𝑜𝑚𝑖𝑐 𝑐𝑟𝑖𝑠𝑖𝑠) + 𝛿( 𝐸𝑈) + 𝑒
After regressing the new model, we re-ran the Ramsey RESET test and found that we
were then able to accept H0 and deem the model to be in correctional functional form and
have no omitted variables at 1% and 5%.
The VIF test for multi-collinearity was also conducted again with Model 2. This time
lnGDP was the only variable to display any multi-collinearity, while inflation no longer did.
This can be seen as an achievement, with the new mean value being 39.94 as compared to
11.47 from Model 1. The new model far exceeded the decision rule cut-off of 10.
Other impacts of the model transformation were an increase in the R2 to 0.9991,
meaning that the independent variables were then accounting for approximately 18% more of
the variation in migration. A re-conduction of the Jarque-Bera test also showed the errors had
become normal in the new model. The Breusch-Godfrey test demonstrated a negative impact
of model 2, with serial correlation becoming present in all 3 lags. All other tests maintained
the same results, with slightly different values used for calculation purposes.

Conclusions and Recommendations
From this study, we have been able to conclude that migration is greatly affected by
the variables we included, to varying extents for each individually.
The fact that the EU variable had a negative coefficient could provide an indication
that the Greek authorities may need to reconsider their membership. If this coefficient is true,
it is clear that people living in Greece do not like being a part of the EU. The economic crisis
also occurred at similar time to EU membership, so it would be worth considering the
relationship between these 2 variables in order to stabilise Greek society.
The negative net migration in Greece requires some attention to bring it back to a
positive figure. The government could consider moving away from austerity measures to
boost investment. This would in turn entice people to stay in, or migrate to Greece.
As a result of this study, we are confident to say that if Greece can reclaim control
over its economic position, the whole society will be able to achieve a greater state of calm.
Almost all of the variables in the model would be improved upon if Greece is able to
strengthen itself.
In future studies on this topic, it would be beneficial to further reduce levels of multi-
collinearity, and to eliminate the serial correlation that became prevalent in model 2. These
objectives could be achieved by transforming the model again, or by omitting any
insignificant variables.
