This study refers to Okun's Law on the economy in North Sumatera Province. Difference with previous studies, in this study the data used is not aggregate data but the data of each economic sector. In addition, the unemployment variable is proxy with the absorption of labor rate. The data analysis was tested by Granger Causality to determine the direction of the relationship between variables for growth of each economic sectors and absorption of labor. By using the Granger Causality Test analysis we concluded that the agricultural sector has a two-way direction relationship between economic growth and absorption of labor. Mining and Quarrying sector, construction sector, transport and communication sector and services sector only have one-way direction relationship from absorption of labor to economic growth. Electricity, gas and water supply have one-way direction relationship from economic growth to absorption of labor. Three other sectors are sectors manufacturing industry sector; trade, hotel and restaurant sector and finance, real estate and business service have no relationship at all between economic growth and absorption of labor.
Statistical Analysis of Interrelationship between Money Supply Exchange Rates...Atif Ahmed
Several researches have been conducted to study the impact of different macro-economic variables and their influence on government expenditure. By using different statistical tools researchers have examined that how money supply and exchange rate influence the government expenditure. Few other studies also conducted work on the quarterly time series data to examine the long run equilibrium association between the macroeconomic variables.
One of the most pressing problems facing the Kenyan economy is the high rates of unemployment,
which has been erratic over the past few years. To examine the existing relationship between unemployment and
economic growth, this paper employed Johansen Cointegration, error correction mechanism (ECM),
This paper studies the causal relationship between inflation and economic growth in Qatar for the period of 1980 to 2016. A time series analysis of unit roots tests, Johansen cointegration method and Granger causality tests were applied on data. The variables were found to be cointegrated, hence a long run-relationship between them exists. Granger causality test found causality runs from inflation to economic growth.
This paper examine the impact of macroeconomic factors on firm level equity premium. Following
the concept of macro-based risk factor model, we consider macroeconomic variable set of equity premium
determinant. The macroeconomic variables include interest rate, money supply, industrial production, inflation
and foreign direct investment. The macroeconomic variables are not in control of the firm's management. These
are the external factors which affect the company as well as the overall market returns. The Macro-based
Multifactor Model is estimated for the whole sample. It is found that the market premium and the selected five
macroeconomic factors significantly affect the firm level equity premium of non-financial firms. Increase in
market premium, money supply, foreign direct investment and industrial production positively affect the firm
level equity premium while increase in interest rate and inflation negatively affects the firm level equity
premium. These findings are beneficial for the common shareholders, institutional investors and policy makers
to find more specific insight about the relationship between macroeconomic variables and equity premium of
non-financial sectors.
An Ethnographic Investigation of Indigenous Management Thoughts and Practices...AJSSMTJournal
The application of Western management theories and philosophies in African societies have
been called to question by scholars, thus igniting calls for management principles and practices that reflect the
contextual nuances and environmental challenges of Africa. This paper examined the indigenous traditional
practices of Ido people of Kalabari, an Ijaw tribe in Rivers State, Nigeria, with a view to identifying the precolonial management thoughts and practices embedded in them. This is an ethnographic study which adopted
interviews, group discussion and observation as sources of data collection. Adopting the judgemental
sampling technique, 15 critical stakeholders of Ido Community – six males and nine females participated in the
interview and focused group sessions while the researchers lived as participant observers in the community to
identify the prevailing management practices and their underlying philosophy. The results of the study indicate
that the Ido people were already utilising indigenous management principles and practices before the advent
of colonialism. It was concluded that there is urgent need for more investigations into the traditional practices
of Africa and other developing economies to discover indigenous management theories and practices of these
geographies that will take cognizance of their contextual nuances and environmental peculiarities in order to
proffer solutions to their peculiar challenges.

Analysis of factors affecting urban per capita housing area in ChinaIJAEMSJORNAL
Housing problems have become one of the hottest topics, influencing people's livelihood and national economy. This paper intends to re-analyze the per capita housing area, which characterizes the residents' happiness index, in order to measure the basic living condition. Taking into account of the large expansion of the floating population in the process of urbanization, we choose “urban resident population” to amend the “registration population”, which is the denominator of the index. We selected the data of residential investment, urban residents' consumption level and residential completion area from 1978 to 2015 to analyze the influence of independent variables on the per capita housing area, we found the volatility of housing price, which reduces the average level of urban per capita housing empirically.
The study investigates the relationship between the labor force participation rate for both male and female, gross fixed capital formation, and economic growth in Bangladesh using the annual time series data from 1991 to 2017. The results find two bidirectional nexus that one is between total labor force participation and economic growth and second is between gross fixed capital formations and economic growth whereas the findings also show a unidirectional causal association from female labor force participation to economic progress for Bangladesh. The study also finds that both total labor force participation and female labor force participation have short-run positive significant effects on the economic development for Bangladesh but adverse effects in the long run. On the contrary gross fixed capital formation contains short term significant negative indication on the economic growth but has an explicit positive considerable impact on the economic development of Bangladesh. The government of Bangladesh needs to give more importance in technical education format that will produce more skilled labor.
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.

Multiple Roles at Conflict: Reflections from Life Career Families in Western ...inventionjournals
Role conflict of employed women in life career families has become an inevitable subject for discussion in the context of recent globalization. Women’s liberation movements in the last centuries expanded the opportunities for qualified women in India to enter in to the workforce for personal satisfaction and supplemental income in family. In this changed social milieu women who once occupied only familial roles are now entering into the labor force taking up different professional roles. Thus playing several roles simultaneously with inadequate time and energy often creates conflicts in the role performance of these working women. Data were collected by interview, observation and focus-group discussion methods from 40 women working in different government and non-government sectors in Sambalpur city of Western Odisha. Against this backdrop, the present study makes an humble attempt to explore how the multiplicities of familial and professional roles are creating conflicts among these working women in the life career families. The study discusses how these women are trying to balance their domestic and professional roles.

A Study of Awareness of Cultural Heritage: Sivas Sampleinventionjournals
This study analyzed the awareness of the students at Cumhuriyet University toward the cultural heritage of the city of Sivas. The study set out from the result of another study carried out previously at the exploratory level and limited number of students1 . The findings of the previous study revealed that the cultural heritage of the city was not known enough by the university students. This study followed three-stage process. In the first stage, The Scale of Cultural Heritage Awareness applied in the previous study was developed, and a survey was applied to the students at Cumhuriyet University central campus. In this stage, students’ levels of awareness for the cultural values of the city were detected, and Mann Whitney U and Kruskal Wallis H tests were conducted to determine whether there were differences between various groups. In the second stage of the study, four separate focus groups were created in order to determine the reasons of the low levels of cultural heritage awareness of the students who were reached via pollsters and surveys. The focus-group studies dwelled on the suggestions students developed in an effort to improve students’ views and awareness of the cultural heritage. In the last section of the study, a focus-group meeting was held with the tourism representatives in Sivas, the results of this meeting were shared, and solution offers were developed in order to raise awareness 1 .

The Concept of Bullying In the Figures of a Popular Cartoon: Doraemoninventionjournals
The concept of bullying has now been widely discussed since the accident happened in Pa-Te Junior High School. The rapid development of Internet fosters the spread of bullying incidents through posting the video of bullying. The MOE has set up a system to train the students to protect themselves when they encountered the situation of being bullied. In reality, school bullying happens in every country around the world, and thousands of students wake up afraid of going to school. Internet and mess-media facilitate the spread of school bullying, especially in TV program. The development of mass-media descends the ages of starting watching TV programs for young children. Children love to watch cartoons, no matter which country they are produced. However, the plots of some cartoons reveal the concept of bullying through the behavior of the main figures. Doraemon, which is a very popular cartoon for children to watch, creates some figures that are violent and prefer bullying the main character: Nobita. The existing documents and studies discuss various aspects of school bullying. This study intends to explore the concept of bullying in some popular figures and tries to find out solutions of this problem. After examining the plots of the cartoons and analyzing the figures, this study concludes that bullying types existing in the figures of these cartoons are direct physical attack, indirect physical attack, direct verbal attack and social exclusion from normal group activities. As for the solution for reducing the negative influence of these programs is to strengthen parents’ and teachers’ alert, accompany the children to watch the program, build up sense of empathy, integrate the concept of safety into the program. Most important of all, parents have to help their children to develop their own judgment to judge what’s right or wrong of these cartoon figures’ behaviors

The Effectiveness of Music Therapy on Cerebral Palsy Patients Receiving Rehab...inventionjournals
Objective: To find out the effect of music therapy in cerebral palsy (CP) patients between who received conventional rehabilitation treatments and who additionally received music therapy Methods: In this retrospective study, 50 CP patients who received rehabilitation treatments on a day-ward basis for at least six months, between March 2013 and February 2015, were selected as subjects. Of the 50 patients, 25 received only conventional rehabilitation treatment (rehabilitation group), and the remaining 25 received both the conventional rehabilitation treatment and music therapy (music therapy group). In this study, the results of the Korean-version Denver Developmental Screening Test 2 (DDST-2) and the social quotient (SQ) were confirmed, before and after the treatments. Results: At baseline, no statistically significant differences were confirmed between the rehabilitation group and the music therapy group in terms of gender, age, and diagnosis. Korean-version DDST-2 scores and the SQ score also did not show statistically significant differences between the groups. With the intervention, the music therapy group showed more statistically significant improvements in the gross motor, fine motor, language, and personal-social parts than the rehabilitation group. The music therapy group also showed greater improvement in SQ score than the rehabilitation group, but the difference was statistically insignificant. Conclusion: This study was conducted to prove the effectiveness of the current music therapy program and to investigate the area in which the therapy produces the greatest effect. It is hoped that the therapy would find wider application among children in the future as it showed significant functional improvements in the gross motor, fine motor, language, and personal-social parts in this study
A Primer on Cointegration: Application to Nigerian Gross Domestic Product and...IOSR Journals
This paper examines Gross Domestic Product (GDP) and Export (EXP) of Nigeria between 1970
and 2007 using data from Central Bank of Nigeria’s Statistical Bulletin of 2008 for cointegration. Applying
Autocorrelation Function (ACF), we find that each of the variables (GDP and Export) is non-stationary.
Augmented Engle-Granger reveals that the regression of GDP on Export is actually cointegrated and not
spurious. An error correction model shows that GDP does not adjust to change in EXP in the same time period.
The regression model obtained also shows that the short-run changes in EXP have a positive impact on the
short-run changes in GDP.
The Effects of Minimum Wage, Labor Force, and Economic Growth on Local Revenu...AJHSSR Journal
ABSTRACT: What is known as Regional Original Revenue (PAD) is the main source of income for local
governments.revenues of a region that reflects the level of regional independence. The larger the Original Local
Government Revenue is, the more it indicates the region is able to implement fiscal decentralization and reduce
dependence on the central government.Covid-19 has resulted in impacts on its economy in Bali. This study
involved data from 9 regencies and cities in Bali, with a total of 45 data points obtained from the years 2017 to
2021, using panel regression analysis. The results of the panel data regression analysis showed that the chosen
model was Fixed Effect Model (FEM). Based on the research results, it was found that simultaneously,
minimum wage (UMR), labor force, and economic growth significantly influenced the Original Local
Government Revenue (PAD). The partial results indicate that minimum wage and economic growth have a
positive and significant impact on regional original revenue. On the other hand, the labor force has a negative
and insignificant impact on regional revenue, specifically in the case of Bali province.

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.

An Empirical Study of the Environmental Kuznets Curve for Environment Quality...ijceronline
This paper attempts to examine the determinants of environmental degradation within the framework of Environment Kuznets Curve (EKC) hypothesis using China's city-level panel data from 2003 to 2012. The population agglomeration as well as three types of cities such as municipalities, sub-provincial city and prefecture-level city are considered in our paper. Our empirical results with the whole sample data verified the theory of the EKC hypothesis, which shows a reverse "U" shape between economic growth and environmental pollution. In addition, the effect of population on environmental pollution is quite different among the various types of cities. The results of this study can serve as a useful reference for policy makers in terms of achieving economic and environmental sustainability.
Government Expenditure and Economic Growth Nexus: Empirical Evidence from Nig...iosrjce
This study has examined the impact of public expenditure on economic growth in Nigeria using time
series data for the period 1970-2012. Secondary data were sourced from the CBN, NBS, journals, text books
etc. The adopted model was fitted with three variables: real GDP, capital and recurrent expenditure. The tools
of analysis were the ADF unit root test and ordinary least square multiple regression accompanied by pairwise
Granger causality test. The major objective of this study is to analyse the impact as well as direction of
causality between the fiscal variables and economic growth. All the variables included in the model are
stationary at level. Empirical findings from the study show that there is positive and insignificant relationship
between capital expenditure and economic growth while recurrent expenditure had a significant positive impact
on economic growth. Also, Granger causality test demonstrates a unidirectional causality running from the
fiscal variables to economic growth in validation of the Keynesian theory. Consequently, the study
recommended more allocation of resources for recurrent purposes as well; government should establish the
body that will monitor contract awarding process of capital projects closely, to guard against over estimation of
project cost and stealing of public funds.
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.

Unemployment and Its Determinants:A Study of Pakistan Economy (1999-2010)Muhammad Arslan
This study has been conducted to determine the determinants which cause the unemployment in economy of
Pakistan for the period of 1999-2010. Unemployment is political and social issue in all the countries. In this
foreign direct investment, gross domestic product rate, CPI based inflation rate and population growth rate is
taken as explanatory variables. In this study ordinary least square model is used for determining the results.
Findings of this paper shows that foreign direct investment, gross domestic product rate and CPI based inflation
rate has negative impact on unemployment. Population growth rate has positive relationship with unemployment
and it contributes to unemployment. This study also confirmed the tradeoff between inflation and unemployment.
Degree of economic_freedom_and_relationship_to_economic_growthAnochi.com.
Freedom is an intrinsic element of the life of every person, yet is often noticed only
in the event that attempts are made at limiting it. It is possible today to select many
areas in which it is more or less consciously diminished. One of these is the field of
economic freedom, which may be reduced through bureaucracy for example, as well as
through various forms of concession. The means of preventing this particular
weakening of the development of an economy may be a gradual liberalization of it.
Individuals aspire to gain happiness through the fulfillment of their needs, assistance
in which may be provided by an increase in income. Economic growth triggers an
increase in the income of individuals, but is also equated with an increase in access to
such goods as better medical care or education. On account of this it becomes vital to
investigate the influence of the liberalization of an economy on economic growth

also have a positive impact on per capita income. From the research results, some policy implications are
proposed to minimize the negative impact of natural disasters on per capita income in Vietnam

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

ABSTRACT : This study refers to Okun's Law on the economy in North Sumatera Province. Difference with
previous studies, in this study the data used is not aggregate data but the data of each economic sector. In
addition, the unemployment variable is proxy with the absorption of labor rate. The data analysis was tested by
Granger Causality to determine the direction of the relationship between variables for growth of each economic
sectors and absorption of labor. By using the Granger Causality Test analysis we concluded that the
agricultural sector has a two-way direction relationship between economic growth and absorption of labor.
Mining and Quarrying sector, construction sector, transport and communication sector and services sector only
have one-way direction relationship from absorption of labor to economic growth. Electricity, gas and water
supply have one-way direction relationship from economic growth to absorption of labor. Three other sectors
are sectors manufacturing industry sector; trade, hotel and restaurant sector and finance, real estate and
business service have no relationship at all between economic growth and absorption of labor.
KEYWORDS - Economic Growth, Absorption of Labor, Granger Causality
I. INTRODUCTION
One indicator to observe of regional development is Gross Domestic Product that classified into nine
sectors of the industry: (1) agricultural, livestock, forestry and fishery; (2) mining and quarrying; (3)
manufacturing industry; (4) electricity, gas and water supply; (5) construction; (6) trade, hotel and restaurant; (7)
transport and communications; (8) finance, real estate and business service, and (9) services. The aggregate of
all sectors of the economy is representative of the economy from an area or region. Increase or decrease of the
Economy will be shown from GDP in the area or region.
On the other hand, the GDP is expected to increase in the unemployment rate will decrease or increase
absorption of labor level. Classical economists such as Adam Smith, David Ricardo and Thomas Robert
Malthus argued that there is always a race between the rates of output growth with the rate of population growth
eventually won by population growth. Because the population also identical as labor, there will be difficulties in
the availability of jobs. If people can get a job, then it will be able to improve their welfare. But if it does not get
a job, it means there will be unemployment, and eventually will depress living standards will be lower.

In aggregate the achievement of the success of economic development as measured by GDP in line
with the high labor absorption as measured from the open unemployment rate shows the direction in accordance
with the pattern and development. When GDP increases, absorption of labor will also increase and vice versa if
the GDP decreased the absorption labor will also fall. However, when we did the analysis partially between
economic sectors with the level of absorption of labor in the North Sumatera province, the result will be
different.

actually absorb most large workforce as well as any sectors which absorb very little labor in North Sumatra
province by economic growth sectors.
II. LITERATURE REVIEW
There are three important macroeconomic variables used by the economists to measure economic
performance. These variables are the gross domestic product, the unemployment rate, and the consumer price
index (CPI). In 1962, Arthur Okun, is specifically examining the relationship between two of the three variables
in macroeconomics that economic growth in terms of output with the unemployment rate. Results of the study
became known as Okun's Law. Based on Okun's Law, the number of unemployed is negatively related to the
level of a country's economic growth. Growth in Gross Domestic Product (GDP) that is closer to 2 percent
would reduce unemployment by 1 percent (Mankiw, 2007).
Some economists have followed Okun (1962) to examine the relationship between unemployment and
output to get an estimate Okun coefficient. Economists include: Smith (1975), Gordon (1984), Prachowny
(1993), Weber (1995), Moosa (1997a, 1999), Attfield and Silverstone (1998), Lee (2000), Harris and
Silverstone (2001), and Silvapulle et al (2004). These studies generally support the empirical validity of the
relationship of unemployment and output but Okun coefficient estimates vary substantially across countries and
over time.
Moosa (1997) examined the Okun's Law in G7 countries (US, Japan, Germany, France, Britain, Italy
and Canada). By using Harvey, Moosa extracting time series data before regressed using ordinary least squares
(OLS), rolling OLS, and seemingly unrelated regression (SUR). Moosa find Okun coefficient differences in
each country studied. Subsequently, Lee (2000) examined the relationship in Okun's Law of 16 OECD countries
in post-war world. Lee using difference model and gap models as contained in Okun's Law. For gap models,
Lee analyzing and building data by alternative methods, namely HP filter, BN decomposition method, and based
on the Kalman filter NAIRU framework. Lee discovered that the labor market and industrial structure in
developed countries have evolved in new ways, so that the relationship between output and unemployment
feasible to re-examination.
Studies on Okun's law is also done by Knotek (2007), which examines the relationship between real
GDP and unemployment in America. Knotek found that Okun's law is not a significant relationship. There are
many exceptions in Okun's law, or instances where the decline in output growth does not always coincide with
rising unemployment. This is true when looking for long term and short term. It is a reminder that Okun's law is
contrary to the connotations of the word "law", only a rule of thumb, not a structural feature of the economy.
3. Using Granger Causality To Examine The Relationship…
www.ijbmi.org 40 | Page
In the region of Southeast Asia, the research ever conducted by Noor et al. (2007), which examines the
existence of Okun's Law in the Malaysian economy have negative relationship between unemployment and
output (GDP). From these studies they found that there is a negative relationship between output and
unemployment where the coefficients obtained are -1748 and it is known that unemployment is one of the
factors affecting changes in output in Malaysia. Granger causality test also showed that there is a two-way
direction relationship between unemployment and output variables (GDP).
Time series analysis model is then used by Petkov (2008) tested the Okun coefficient in the UK.
Petkov using analytical tools autoregressive distributed lag model (ARDL) approach Hodrick-Prescott filter (HP
filter). This approach is used to capture the phenomenon Petkov NAIRU and then followed up by applying the
Error Correction Model (ECM) to get Okun coefficient. Petkov prove that there is a relationship between output
growth and unemployment. But Okun found Petkov coefficient value is different from the original version of
Okun coefficient. Then Arshad (2010) using the gap equation and techniques Hodrick-Prescott Filter (HP) found
empirical evidence that there is a negative and significant correlation between GDP and unemployment in the
short term strengthening Okun's Law (1962). For the long term, used Cointegration Test and Error Correction
Model (ECM) shows that GDP and unemployment cointegrated with one another in the long term.
Sectoral studies and using proxy variables for unemployment ever undertaken by Hanusch (2012),
which discusses the economic growth and unemployment using data from eight East Asian countries during
1997 to 2011 period to get the coefficient of Okun's Law that shows the relationship between economic growth
and employment. The results show that the effect of economic growth in reducing unemployment, but there are
variations in different countries. Economic growth affects employment, though not in the aggregate, but in its
composition. There is evidence that employment in the agricultural sector move counter-cyclically, where the
effect in a period of crisis, the agricultural sector can serve as a shock absorber to reduce the impact of layoffs in
the industrial sector.
III. RESEARCH METHODOLOGY
The analytical method used in this research is quantitative analysis. The data used are the growth of
GDP and absorption of labor in North Sumatra province period 2000-2014. Because macroeconomic time-series
data tend to be non-stationary, Unit Root Test using Augmented Dickey-Fuller Test (ADF) will used to
determine the data is stationary or not. Second, using Granger Causality Test to determine the relationship of
economic growth and absorption of labor, either one-way or two-way direction relationship.
IV. FINDINGS AND DISCUSSION
Stationarity test
Testing unit root in this research model is based on Augmented Dickey Fuller (ADF) test to determine
that a series has a unit root or not, there should be a comparison between the value of t-statistic with ADF table
or probability with alpha (1%, 5% or 10%). If the absolute value of the t-statistic on the ADF Test is smaller
than the critical value of the ADF in the table with a certain level of significance, the data time series is not
stationary.
Based on the results of the unit root test on the level as shown in Table 1 below was found that the
variables have a unit root, which means that the original data is not stationary research as well as on the level of
the first difference.

Testing unit root at the second level difference indicates that all data has been stationary. This can be
seen from the absolute value of the ADF statistic greater than Mc Kinon Critical Value on the critical value of
1%, 5% and 10%. Thus it can be explained that all the variables to be estimated in this study have been
stationary at the same degree that the second difference.
Grangers Causality Testing
On the Granger causality test carried out on a second difference data. This is considering the level data
is not stationary, and will lead to spurious regression. Testing with the Grangers Causality is intended to
examine the relationship between variables. Table 2 showed the result of Granger's Causality method using the
second difference data.
The economic sector that has a two-way direction relationship between economic growth and
absorption of labor is agriculture sector, this can be seen from the value of the F-statistic of variable absorption
of labor for the agricultural sector with probability of 0.0267 and F-statistic = 6.73504, significant at α = 5%.
While the F-statistic of economic growth for agricultural sector = 3.58247 with a probability = 0.0877 was
significant at α = 10%.
Sectors which have a one-way direction relationship between the absorption of labor to economic
growth are mining and quarrying sector, it can be seen from the F-statistic of absorption of labor = 0.37544 with
probability = 0.5537 is not significant, while F-statistic of economic growth = 4.66321 with a probability =
0.0562 significant at α=10%. The absorption of labor and economic growth on construction sector is also related
with one-way direction relationship, it can be seen from the F-statistic of absorption of labor = 0.53401 with a
probability = 0.4817 is not significant. While a probability of economic growth = 0.0023 and F-
statistic=16.4383 with a significant probability at α=1%. Absorption of labor to economic growth on
transportation & communication sector also have a one-way direction relationship with F-statistic of absorption
of labor = 0.46689 and probability = 0.5099 is not significant. While the F-statistic of economic growth =
3.81900 with probability = 0.0792 was significant at α = 10%. Services sector has a one-way direction
relationship from absorption of labor to economic growth, this can be seen from F-statistic of absorption of
labor = 0.06134 with a probability = 0.8094 is not significant, While the F-statistic of economic growth =
38.2922 with a probability = 0.0001 was significant at α=1%.

Electricity, gas and water has a one-way direction relationship from economic growth to absorption of
labor, it can be seen from the F-statistic of absorption of labor = 4.50416 with probability = 0.0598 was
significant at α=10%. While the F-statistic of economic growth = 1.12308 with a probability = 0.3142 is not
significant. Three other sectors have no relationship between economic growth and absorption of labor are
manufacturing industry sector; trade, hotel and restaurant sector and finance, real estate and business service
sector.
Knotek (2007) states that Okun's Law has the ability to be used as a practical application. However,
based on the analysis and discussion in this study found that there are differences between the results with the
original version of Okun's Law. Okun's Law phenomenon is not entirely the case in the economy of North
Sumatera province. This could mean that Okun's Law cannot be used as a measuring tool that is valid in
explaining the relationship of economic growth and absorption of labor by sectoral.
Although the research showed unsatisfactory results but Okun's Law may be implicated and play a role in
the process of identifying the problems that are happening in the economy of North Sumatera province. The
study found that the rates of absorption of labor in the economy of North Sumatera province are not responsive
to changes in real output in almost all economic sectors. The cause is the existence of structural
unemployment/frictional in the economy of North Sumatera province and the structural differences between the
economies of developing countries such as Indonesia compared with developed countries. In the developing
countries, labor-intensive still needed in the economy more dominant than skills labor.
Early identification of Okun's Law can be used as a reference by the government in formulating
economic policy. In this case, the government needs to give attention to the sectors that can create jobs.
Especially for agriculture and the informal sector, where the proportion of the ability to absorb labor is still
higher than the other sector. This sector proved to be able to act as a shock absorber in a crisis situation in the
economy.
Practically, Okun's Law is still worthy as one tool to determine the relationship of economic growth and
unemployment, especially for developing countries. To understand this relationship more comprehensive
manner, you can add variables such as the level of labor productivity and the number of hours worked in the
industrial sector (Prachowny, 1993), as well as the need to consider the nature of the variables that are always
changing (Knotek, 2007), the growth of labor force and labor productivity growth (Blanchard, 2009).
V. CONCLUSION
Based on the results of research on the causality relationship between economic growth by sectors and
absorption of labor, it can be concluded economic growth in agriculture sector and absorption of labor in the
agricultural sector has two-way direction relationship. Sectors that have a one-way relationship between
absorption of labor to economic growth are mining and quarrying sector, construction sector, transport and
communication sector and services sector. Electricity, gas and water have a one-way relationship of economic
growth to labor absorption. Three other sectors have no employment relationship between the sector and the
GDP sectors are sectors of industry, trade and banking sector.

VI. RECOMENDATIONS
The government should encourage the growth of productive and absorb a lot of labor, not growth that
are capital intensive. The agricultural sector is still an important factor in the economy of North Sumatra
province, so the government needs to pay special attention to this sector. The attention can be either policy or
legislation to provide special incentives for farmers. In addition, to address structural unemployment / frictional
required special training programs to improve the skills of the workforce according to the needs of sectors such
as mining and quarrying, construction, transport and communication sector and services sector. The
Government also needs to provide training and assistance in the field of entrepreneurship for workers who are
not absorbed in that sector. Advanced testing can use the data to span a longer period. Given the economic
structure in North Sumatera province in the industrial sector began to grow rapidly in the last twenty years
period. As well as the need to be considered to include other variables to understand the relationship of
economic growth and absorption of labor more comprehensively.
