Ball State University RESEARCH METHODS POLS 626 GOVERNMENT EFFECTIVESS AND ECONOMIC GROWTH IN SUBSAHARA AFRICA. By: Nii Narku Nortey Spring, 2021 1 EXECUTIVE SUMMARY The region of Sub-Saharan Africa has experienced low growth rates for an extended period. Though the region abounds in natural resources, its economic growth has been generally subpar compared to countries in the developed world. There have been several studies that examined the growth determinants of the economies of sub-Saharan Africa countries. However, many of these studies are focused on the traditional growth determinants with very little attention on the role of the World Governance Indicators on countries' economic growth in sub-Saharan Africa. In recent times, the focus has shifted to determining the economic performance of countries in the subregion. Therefore, the crux of this study is to examine the impact of government effectiveness on the economic growth of sub-Saharan Africa. The study made use of panel data analysis using a sample of 43 countries from1996 to 2016. The study revealed that government effectiveness does not have any significant effect on economic growth of countries in sub-Saharan Africa. Among the five governance indicators included in the model as controls, only political stability significantly affected economic growth in sub-Saharan Africa. The study recommends that governments in sub-Saharan Africa should give priority to all the WGI indicators variables. All these indicators need to be enhanced to improve economic growth in sub-Saharan Africa. The study further recommends a public-private partnership between government agencies and the private sector to enhance the efficient allocation of resources through innovative ideas and policies. Additionally, the government should invest in research and development to advance innovative solutions to the complex challenges that hinder productivity in the public sector at local, regional, national, and international levels. 2 CHPATER ONE INTRODUCTION Sub-Saharan Africa is known for its abundant natural resources, but it has lagged in development and growth. The region's growth rates have been unsustainable and among the lowest globally, but research into the dynamics of change has concentrated chiefly on traditional economic determinants (Acemoglu et al. 2004). Following Barro's (1991) pioneering work, several other economists have made significant efforts to define the fundamental factors that account for economic growth differences between and within countries and continents worldwide. For instance, Sawyer (2010) attests that SSA's economic growth has slowed due to low total factor productivity growth (TFP). Dollar and Kraay (2003), whiles throwing their support for macroeconomic policies, averred that trade shares have a positive long-run effect on economic performance. Stern (1993) incorporated employment and capital in a model and found that increased energy consumption results in growth in real GDP. Similarly, Dawson (2003) finds that the economy can improve economic performance through the positive effect on investment. The earnest desire to understand the development needs of this deprived continent of the globe indicates that the critical determinants of economic growth might not account for the dynamics of countries in SSA (Easterly and Levine, 1995). Through the Solow growth model in a multicountry sample, several scholars have carried out studies and found an inverse and significant effect of other factors affecting growth aside from the traditional growth determinants. Levine and Renelt (1992) found that other variables such as income distribution, government size, and trade openness are critical drivers to economic growth. Other scholars also found institutional quality as a driver of economic growth and (Sala-I Martin, 1997a, 1997b; Barro, 1991, 1997; Bloom and Sachs 1998). According to Fayissa and Nsiah (2013), good governance, or the lack 3 thereof, contributes to the disparities in African development. Good governance is a strong determinant of economic growth, and it helps to understand why countries have different levels of development. According to Schneider (1999), good governance is the exercise of authority or power over a country's affairs and wealth. On the other hand, the United States Agency for International Development (USAID, 2002) describes good governance as a complex system of interaction among institutions, practices, functions, and processes characterized by values of accountability, openness, and participation. The UNDP (2002) defines good governance as striving for the rule of law, transparency, equity, effectiveness /efficiency, accountability, and strategic vision in political, economic, and administrative exercise. Many studies have used the World overall indexes of World Governance Indicators as a proxy for governance (Fayissa and Nsiah 2013; Muhammad et al. 2015; Kilishi et al. 2013) and institutional quality (Levine and Renelt 1992; Barro, 1991, 1997; Bloom and Sachs 1998), while controlling for other macroeconomic determinants of growth. The World Governance Indicators are voice and accountability, political stability, government effectiveness, regulatory quality, the rule of law, and control of corruption. According to existing literature, the role of governance indicators in institutions on economic growth has not been clearly defined with support of relevant evidence (Pistor, 1995; Eweld, 1995). Additionally, only fewer studies have considered how each of these indicators affects subSaharan Africa while controlling for the other governance indicators, the traditional determinants of growth (labor and capital), and macroeconomic factors of development (Example, unemployment, inflation, trade, etc.). Therefore, there exists a gap in the literature concerning the exact role each governance indicator plays in the economic growth dynamics of SSA. Thus, 4 the study examines the relationship between government effectiveness and economic growth in a sample of 43 countries in SSA spanning from 1996-2016. Specifically, the study aims to: 1. To estimate the impact of government effectiveness on the economic growth of SSA from 1996 to 2016. Henceforth, the study intends to find answers to the following questions; 1. Does government effectiveness have any impact on economic growth in sub-Saharan Africa from 1996 to 2016? 5 CHAPTER TWO LITERATURE REVIEW According to contemporary growth theories, differences in economic growth between countries and regions can be attributed to factors such as institutional efficiency (Easterly et al., 2004; Acemoglu et al., 2003a). According to North (1990), governmental institutions and entities can be defined as humanly-devised constraints that mold people's interactions and influence and shape the incentives of economic operators. In the presence of good governance, there are higher chances of prospering economic growth due to the promotion of more sharp divisions of labor, faster implementation of economic and social policies, and more productive investments (Alam, Kiterage, & Bizuayehu, 2017). Higher economic growth is facilitated by good governance, which encourages more effective labor units, more profitable investment, and faster implementation of social and economic policies (United Nations 2005). According to Hall and Jones (1999), institutions and government policies shape the economic climate in which people acquire skills and businesses acquire capital and generate production. Although good governments can boost economic development by efficiently providing social infrastructure that prevents diversion, bad governments can cause a public diversion in an economy through expropriation, confiscatory taxes, and inadequate regulations and laws (Hall and Jones 1999). Alam et al. (2018) examined the influence of government effectiveness on the economic development of a panel of 81 countries using a Generalized System Method of Moments (System GMM) technique. The study discovers that government effectiveness has a substantial positive impact on economic development. In a survey spanning 73 developed and developing countries from 1975 to 1990, Adkins and Savvides (2002) found that countries with greater economic 6 freedom have higher growth rates. In a similar vein, Dawson (2003) finds that economic efficiency can be improved through a positive impact on investment. According to Bassam (2013), the associations between economic growth and governance quality are highly dependent on levels of human development and the metrics used to measure governance quality. North (1990) demonstrates that institutional structure strongly influences how economic and political results are connected. Kaufmann and Kraay (2002) analyzed 175 countries in 2000/01, concluding that good governance is needed for high per capita income and economic growth. Knack came to the same conclusion (2002). Huynh and Jacho-Chavez (2009) investigated the relationship between governance and growth using a nonparametric approach. Their results show that three of the six indices of governance are economically and statistically significant: voice and transparency, political stability, and the rule of law, while regulatory regulation, corruption control, and government effectiveness are insignificant. Emara and Jhonsa (2014) investigated the interrelationship between improved government efficiency and increased per capita income using the Two-Stage Least Square method for a cross-sectional dataset of 197 countries. Their results show that the standard of governance has a clear positive and statistically meaningful relationship with per capita income. Guisan (2009) compared European countries to the United States and Canada from 2000 to 2007, looking at the relationship between government efficacy, education, and economic growth. The findings of the author demonstrate the significance of government effectiveness in economic growth. Cebula and Foley (2011) examined the impact of high-quality government regulation on per capita real GDP by using panel data and PLS estimates for OECD countries throughout 7 2003-06. The authors conclude that better regulatory efficiency is positively correlated with economic growth. 8 CHAPTER THREE THEORY AND HYPOTHESES In recent times, some amount of work has been done, especially concerning the role institutions tend to play in determining the growth of countries. Given this, several academic researchers have been conducted to provide further evidence on the impact of governance indicators and how they affect economic progress. The role of these indicators has not been well defined in some of the past studies (Pistor, 1995). Therefore, it is essential and timely to determine the exact role of these governance indicators and other traditional growth determinants in the growth matrix of SSA countries. Based on the above, the study developed the following hypotheses: The debate about whether governance indicators have a positive or negligible impact on economic growth is raging. Hypothesis (1): The study hypothesized that government effectiveness positively impacts economic growth in Sub-Saharan Africa. Hypothesis (2): The study hypothesized that political stability, voice, and accountability, regulatory qualities, raw of law have a positive impact on economic growth in Sub-Saharan Africa. Hypothesis (3): The study hypothesized that control of corruption negatively impacts economic growth in Sub-Saharan Africa. The effects of human and physical resources on economic development are debatable. Although several scholars claim that human and physical capital foster economic growth (Barro, 1992), 9 others argue that human capital and labor do not explain economic growth (Barro, 1992). (Benhabib & Spiegel, 1994) Hypothesis (4): The study hypothesized that physical capital positively impacts economic growth in Sub-Saharan Africa. Hypothesis (5): The study hypothesized that human capital positively impacts economic growth in Sub-Saharan Africa. Although some economists (e.g., Yanikkaya, 2003) argue that net trade (trade openness) harms economic growth, especially in developing countries, others (e.g., Romer & Frankel, 1999) say that it has significant positive effects. Hypothesis (6): The study hypothesized that net trade positively impacts economic growth in Sub-Saharan Africa. 10 CHAPTER FOUR DATA AND ESTIMATION 4.1 Introduction The chapter focused on various strategies that were adopted to achieve the goals of the study. Specifically, this chapter looks at the model specification, variable definitions, empirical or estimation approach, and data sources. 4.2 Model Specification According to the Solow model, production or growth is a function of capital and labor. In this model, production is dependent on the amount of capital stock and labor applied in the production process in the economy (Solow, 1956). Therefore, the basic model is stated as follows: Y= f(K, L ).................................................................................................3.1 Where Y=Economic Growth (Real G.D.P.), K= Capital Stock, and L= Labor Equation 3.1 is adjusted to account for government effectiveness and the selected control variables. According to Acemoglu et al. (2003a), Apart from the traditional growth determinants such as capital stock and labor, institutional Quality also constitutes the reasons for the differences in economic growth between countries and regions. The study assumed a linear relationship between growth, factors of production, government effectiveness, and control variables. Therefore, to account for the linearity, the regression model in 3.1 is modified as follows; Y = β0+ β1GE+ β2PS+ β3VA+ β4CCo+ β5RL+ β6RQ+ β7K+ β8L+ β9NT+ β10EM+U….3.2 11 GE=Government Effectiveness, PSAV=Political Stability and Absence of Violence, VA= Voice and Accountability, CCo= Control of Corruption, RL= Rule of Law, RQ= Regulatory Quality, NT=Net Trade, EM=Employment. Economic growth in real G.D.P. is the dependent variable. Government Effectiveness is the primary explanatory variable, U is the error term, and all other variables are the control variables for the study. 4.3 Variables Definition The study used the Worldwide Governance Indicators (W.G.I.) and World Development Indicators (W.D.I.). The variables are defined below. 4.3.1 Economic Growth G.D.P. is a measure of the total economic value of final goods and services in an economy (Todaro and Smith, 2011). It is the continuous increase in the output of an economy resulting in an expansion of economic activities a country. It involves the increase in the inflation-adjusted market value of the goods and services produced in an economy over time. 4.3.2 Government Effectiveness Government effectiveness measures the superiority of public services, the Quality and degree of independence from political demands of civil service, the Quality of policy formulation and implementation, and the reliability of the government’s ability to ensure the sustainability of policies. 4.3.3 labor Labor refers to the effort of a man used in the production process of goods and services. It is the aggregate of all human action used in the creation of goods and services. These factors determine 12 economic growth in an economy. Ghosh (2011) proved that there is a long-run relationship between labor and economic growth. 4.3.4 Physical Capital Capital refers to the machinery, tools, and buildings used to produce goods and services in a country. It could take the form of computers, buildings, and vehicles used differently based on the kind of labor the work requires. The amount of capital accumulation in an economy determines its level of growth. Ellahai (2011) included capital in his model to measure the effect on economic growth. 4.3.5 Political Stability Political stability and absence of violence is an index that measures the perceptions of the likelihood that the government will be destabilized or overthrown by unconstitutional or violent means, including domestic violence or terrorism. 4.3.6 Voice and Accountability Voice and accountability show how a country’s citizens can choose their government and enjoy the freedom of speech, freedom of association, and free media. The level of participation by both men and women indicates that freedom of association and expression and an organized civil society are vital to achieving voice and accountability. 4.3.7 Control of Corruption Control of corruption measures the magnitude to which public power is used for private gain. It also includes petty and grand forms of corruption and “capture” of the state by elites and personal interests. 13 4.3.8 Rule of Law The rule of law measures the extent to which agents have confidence in and abide by society’s rules, particularly the Quality of contract (private and government) enforcement, the police, and the courts, as well as the likelihood of crime and violence. 4.3.9 Regulatory Quality Regulatory Quality measures the capability of the government to formulate and apply comprehensive policies and regulations that allow and encourage private sector development. 4.3.10 Net Trade Trade openness involves transferring goods produced in one country to another, either for further processing or for consumption. Shahbaz et al. (2010) included net trade as a control to estimate the effects of energy on economic growth.

The institutional quality indicators were gathered from World Bank’s Governance Indicators (W.G.I.) from 1996 to 2016. The institutional quality variables are political stability and absence of violence, voice and accountability, control of corruption, the rule of law, regulatory Quality, and government effectiveness. G.D.P. per capita growth (annual percentage) is the dependent variable, government effectiveness is the primary explanatory variable, capital stock, labor, and the other institutional quality indicators constitute the control variables. 3.5 Data Type, Estimation Strategy, and Analytical Tool The study made use of a panel data set and simple regression analysis as the estimation strategy. 3.5.1 Data Type The nature of the variables under observation meant a panel data set was ideal for this type of study. A panel data set spanning 20 years (1996 – 2016) gathered from 43 Sub-Saharan African countries were put used for the analysis. As Wooldridge points out, a multiple observation on the same units makes it easy to control for specific unobserved characteristics in a variable (Wooldridge, 2016). He went on to say that using multiple observations of a variable from different times will help with causal inference in cases where inferring causality would be complex with just a single cross-section data (Wooldridge, 2016). 15 3.5.2 Estimation Strategy Multiple regression analysis was the estimation strategy for the study. The researcher found this estimator the most appropriate because it allows for controlling other explanatory variables that jointly affect the dependent variable. Thus, it is easy to apply the ceteris paribus principle (keeping other variables constant) to our interpretation. When dealing with nonexperimental results, the use of ceteris paribus is essential for testing economic theories and assessing policy effects (Wooldridge, 2016). The multiple regression analysis was used to deal with economic variables and government policies, including several control variables. 3.5.2 Data Analytical Tool The regression analysis was computed using the Statistical Package for Social Sciences (SPSS). In the social sciences, it is the most commonly used programming tool for statistical analysis. SPSS is an incredibly effective software for manipulating and deciphering survey data, thanks to its focus on statistical data analysis. 16 CHAPTER FIVE RESULT AND DISCUSSION 5.1 Heteroskedasticity Test The researcher performed the Breusch-Pagan test to confirm the presence or absence of heteroskedasticity. None of the variables explained the square residuals at the 5% critical value. Additionally, the F-test for joint statistics was 1.67 with a p-value of 0.082 (See Appendix A). It is not significant at the 5% critical value, indicating a very small or the absence of heteroskedasticity. 5.2 Descriptive Statistics The descriptive statistics cover only the mean, standard deviation, minimum and maximum values. Table 4.1 reveals these results. Table 5.1 Descriptive Statistics Variables (N) Min Max Mean Std. Deviation GDP 903 -36.83 140.5 2.45 7.93 Capital (K) 725 -294.16 2357.68 12.83 94.85 Labor (L) 861 Voice & Accountability (VA) 903 -2.23 9.85 -.622 .79 Government Effectiveness (GE) 903 -2.19 1.11 -.70 .68 Regulatory Quality (RQ) 903 -2.29 1.13 -.65 .61 Control of Corruption (CCo) 903 -1.81 1.22 -.64 .59 Political Stability (PS) 903 -2.04 1.28 -.55 .89 Rule of Law (RL) 903 -2.13 1.08 -.70 .64 Employment (EM) 882 88.94 64.28 13.41 Net Trade (NT) 862 311.36 73.13 36.46 Valid N (Listwise) 692 453006.0 848442 35.28 17.85 17 631350.3 119482.2 The standard deviation (7.93) for GDP shows a considerable variation from the mean (2.45). It implies that there is a wide variation in growth rates among the countries in SSA. Therefore, we can describe the growth rate across all countries in the sample as unstable and inconsistent. The minimum (-294.16) and maximum (2357.68) values of capital are very far away from the mean (94.85), indicating a wide discrepancy in the data set for all the countries in SSA. The widespread among the variables is further confirmed by a standard deviation of 94.85. It indicates variations and inconsistency in the performance of capital as a factor of production. The mean (631350.3) for labor shows that it plays a perfect role in performance across all subregion’s countries. The standard deviation (119482.2) is below the mean, indicating that the data is spread close to the mean. It shows a consistent performance of labor in all the countries across the region. 5.2 Regression Analysis Table 5.2 Effects of Government Effectiveness on Economic Growth in Sub-Sahara Africa Variables Model 1 Model 2 Model 3 Government Effectiveness (GE) 0.096 (.390) 0.933 (.786) 0.893 (.878) Voice & Accountability (VA) 0.115 (.500) 0.052 (.722) Regulatory Quality (RQ) -1.174(.917) -0.670 (1.148) Control of Corruption (CCo) -0.671(.889) -0.484(.964) Political Stability (PS) 1.083 (.473)** 1.626 (.577) ** Rule of Law (RL) -.786 (1.288) -1.155 (1.563) Capital (K) .007 (.003)** Log-Labor (L) 0.014 (.380) Employment (EM) 0.028 (.025) Net Trade (NT) -0.002 (.010) Constant 2.521 (.381)*** 2.029 (.414) *** 0.562 (3.123) (Adj.)

Model 1 tested only the primary explanatory variable (government effectiveness) on GDP per capita. The result shows that government effectiveness does not explain GDP in Sub-Sahara Africa. Model 2 tested all the World Governance Indicators on GDP. The result revealed that only political stability is statistically significant with GDP at the 5% critical value. The relationship was also positive. Model 3 tested all the explanatory variables on GDP. The result showed that political stability and capita GDP have positive and significant effects on GDP at the 5% critical value. The rest of the explanatory variables were insignificant to GDP; thus, they could not explain the variable in GDP in the region. The regression results showed an insignificant and positive relationship between Government Effectiveness and real GDP per capita growth in SSA. This finding does not conform to the study of Kilishi et al. (2013) and Guisan (2009). Their studies on Africa predicted a positive and significant relationship between government effectiveness and economic growth in Africa. Similarly, Guisan (2009) compared European countries to the United States and Canada from 2000 to 2007 and found a significant relationship between government effectiveness and economic growth. The positive and statistically significant relationship between political stability and GDP per capita is inconsistent with the findings of Yildirim et al. (2015) but consistent with Sokoloff and Engerman (2000). Yildirim et al. found political stability to have a negative impact on the macroeconomic performance of developing countries. However, Sokoloff and Engerman (2000) opined that stable democracy reduces inequality and enhances the economic prosperity of 19 developing countries. Therefore, this study’s findings on political stability confirm the conclusions of Sokoloff and Engerman (2000). The positive and statistically significant relationship between capital and GDP per capita means that a capital increase will increase per capita GDP growth in SSA. The coefficients of physical capital being significant and positive conform with the a priori expectation that capital contributes positively to economic growth. The results confirm the relevance of the augmented Solow model in explaining Africa’s growth (Solow 1956). Investment in physical and human capital is vital in promoting rapid growth in Africa. 20 CHAPTER SIX CONCLUSION AND RECOMMENDATIONS 6.1 Conclusion The study attempted to estimate the effect of government on economic growth in sub-Saharan Africa. Based on the results, the study concludes that government policies and economic regulations do not impact economic growth in Sub-Sahara Africa. The study further concludes that only political stability out of the six World Governance Indicators (WGI) is crucial to economic growth and development in Sub-Sahara Africa. 6.2 Recommendations In the first place, governments in sub-Saharan Africa should prioritize all the WGI indicators variables since all the indicators showed an insignificant relationship with GDP except for political stability. All these indicators need to be enhanced to improve economic growth in subSaharan Africa. The study further recommends a public-private partnership between government agencies and the private sector to enhance the efficient allocation of resources through innovative ideas and policies. Additionally, the government should invest in research and development to advance innovative solutions to the complex challenges that hinder productivity in the public sector at local, regional, national, and international levels. 21 REFERENCES Acemoglu, D. et al.
