The Eubank findings on taxation, political accountability and foreign aid have had an important influence on academic and policymaking debates. Eubank has warned that his findings should not be generalised across Africa until they are backed by robust empirical evidence. This paper puts some empirical structure to the celebrated literature. The empirical evidence which is based on data from 53 African countries for the period 1996‐2010 broadly confirms the Somaliland‐based Eubank hypothesis that in the absence of foreign aid, the dependence of government on local tax revenues provides the leverage for better political governance. 相似文献

We estimate changes in the distribution of household consumption expenditure in Namibia since independence in 1990 and the effects on poverty. To produce comparability between two household surveys, we use survey‐matching techniques, and we apply the framework of stochastic dominance to test the robustness of our results. The results reveal a significant decrease in the poverty headcount over the period and small but insignificant decreases in the country's extremely high levels of inequality. Decomposition analysis shows that poverty reduction in Namibia is largely driven by growth in mean incomes rather than redistribution. Even so, there have been important changes in inequality among different social groups especially as educational attainment has replaced ethnicity as the main determinant of between‐group inequality. 相似文献

This paper examines the microeconomic effects of macroeconomic policies or shocks in South Africa. In particular, the paper considers the effects of macroeconomic policies on poverty and inequality by building and linking a microsimulation (MS) model to a Computable General Equilibrium (CGE) model. In the South African context, where poverty and inequality are at high levels, this novel approach enables us to identify the winners and losers of any policy change, so that the impact on poverty and inequality can be assessed in detail. 相似文献

In this study, we examine dynamic spillovers among the housing market, stock market, and economic policy uncertainty (EPU) in the United States in a unified empirical framework. Applying the Diebold and Yilmaz (2012) methodology on monthly data over the period 1987M1–2014M11, our findings reveal the following features. First, the transmission of various types of shocks contributes significantly to economic fluctuations in the United States. Second, spillovers show large variations over time. Third, in the wake of the global financial crisis, spillovers have been exceptionally high in historical perspective. In particular, we find large spillovers from EPU, as well as stock market and housing returns to other variables, in particular inflation, industrial production and the federal funds rate. These results illustrate the contagion from the housing and financial crisis to the real economy and the strong policy reaction to stabilize the economy. 相似文献

In examining some big questions on African development, I provide evidence that the dynamics of some development indicators could support both endogenous and neoclassical growth theories in the convergence debate. This paper investigates convergence in real per capita gross domestic product and inequality‐adjusted human development in 38 African countries, disaggregated into 10 homogenous panels based on regions (Sub‐Saharan and North Africa), income levels (low, middle, lower middle and upper middle), legal origins (English common law and French civil law) and religious dominations (Christianity and Islam). The main finding is that the income component of the Human Development Index moves slower than others in the convergence process, and thus requires a more focused policy intervention. As a policy implication, looking beyond income convergence can provide a concrete agenda for development involving all aspects of economic, institutional and social life. 相似文献

The law and finance theory essentially states that legal origins are a significant determinant of financial development. The conclusion from the law and finance theory is that countries whose legal traditions derived from British Common Law have better developed financial markets than countries following French Civil Law. This study conducted an empirical investigation of the law and finance theory for African countries. Our empirical results showed that legal origins are insignificant in explaining financial development but rather, legal effectiveness significantly explains cross‐country differences in financial development in Africa. We concluded that the law and finance theory does not hold in African countries. 相似文献

The large number of overweight children in the United States has prompted school administrators and policy makers to identify practices in schools that contribute to unhealthy weight outcomes for children and develop strategies to prevent further increases. Advocates for school nutrition reform have suggested that it is important for children to have an adequate amount of time to eat meals in school in order to maintain a healthy weight. This article examines whether the length of time children are given to eat lunch in school has an impact on their weight. I find evidence that an increase in lunch length reduces the probability a child is overweight, and this finding is robust across various econometric specifications, including a two‐sample instrumental variable model and difference‐in‐differences model that account for the potential endogeneity of lunch length. 相似文献

This paper reviews applications of computable general equilibrium models to trade liberalisation in South Africa. It focuses on economic structure, data, macroeconomic closure and results of the models. The models project that trade liberalisation has had small positive impacts on growth. Poverty and inequality outcomes are less clear cut and depend on the model used. Models with fully integrated micro data find that poverty has worsened slightly while inequality has risen. Aggregated models predict that poverty has been reduced by small amounts. Dynamic models report rising inequality but falling poverty incidence. The paper identifies areas for future research. 相似文献

REGIONAL INTEGRATION OF EQUITY MARKETS IN SUB-SAHARAN AFRICA 总被引:1,自引:0,他引:1

Equity markets in developing and emerging economies have grown in number and importance as a result of financial market globalisation. However, their role in economic growth and development is enhanced if nascent markets are integrated with well‐established ones. Market integration, measured by the transmission of returns volatility, is identified across a sample of SSA countries, using a unique dataset. Evidence for potential integration between financial markets in Sub‐Saharan Africa (SSA) is found. Spillovers are found across markets, some unidirectional and others bi‐directional. However, continued illiquidity and incomplete institutions indicate that an integrated financial community remains premature, and considerable regulatory reform and harmonisation will be necessary for this to succeed. 相似文献

This study examines the relationship between U.S. output growth and its volatility over the period 1876:I to 2012:II. We adjust the data for outliers and structural breaks. We employ generalized autoregressive conditional heteroskedasticity (GARCH) and exponential GARCH (EGARCH) specifications. Normality and homoskedasticity appear only in the GARCH or EGARCH model that corrects for the outliers. When including the break in the mean equation, high volatility persistence remains. After also accommodating the breaks in the variance equation, the integrated GARCH effect proves spurious, either for the symmetric or the asymmetric model. Finally, our empirical results suggest that the finding of higher output growth volatility stimulating output growth and higher output growth reducing its volatility obtained from the symmetric GARCH‐in‐mean (GARCH‐M) model also proves spurious as a result of the emergence of an asymmetric effect. Our more appropriately specified asymmetric EGARCH‐M model suggests positive volatility‐in‐mean and level effects in the long‐period real gross national product series. 相似文献

This article examines the potential medium‐term causal relationship between changes in Gross Domestic Product (GDP) per capita and poverty in developing countries during the 1970s–1990s. For this purpose, we use panel data model evaluation techniques to test the out‐of‐sample forecasting performance of competing models. We conclude that the evidence supports the hypothesis that increases in GDP per capita cause unidirectional poverty reduction, measured by the $1/day poverty rate, in the period 1970s–1980s. The results are similar when analysing low‐ and middle‐income countries and mid‐high‐ and very high‐inequality countries separately. However, in the period 1980s–1990s, it is only statistically significant for low‐income countries. 相似文献

Established illiquidity measures are constructed for emerging markets in Africa and used to determine which best explains trading costs. Costs of equity are derived from an augmented Capital Asset Pricing Model for a sample of emerging financial markets generally ignored in the literature. These include: South Africa and Namibia, three countries in North Africa and four in Sub‐Saharan Africa (SSA), plus London and Paris as examples of integrated markets. Minimum variance portfolios are constructed and asset weights derived, with the sample divided into countries dependent on their legal regime. Portfolio weights are shown to be directly related to well‐regulated markets with high standards of corporate governance and disclosure, and firms seeking cost‐effective finance from SSA stock markets are at a distinct disadvantage compared with those in Northern Africa, South Africa and, in particular, London and Paris. 相似文献

Openness and Total Factor Productivity in Swedish Manufacturing, 1980–1995. — This paper studies the effect of openness on total factor productivity (TFP) growth. Using industry-level data for Swedish manufacturing from 1980 to 1995, the paper shows that integrated industries tend to be more engaged in R&D and have more entry and exit activity than other industries. The results show that domestic R&D intensity does not contribute to the TFP growth rate. Instead, openness to international markets, which helps facilitate technology spillovers, is an important factor. There is also some evidence that producers exiting the market are less productive, implying that such exits will increase the average productivity of the industry. 相似文献

People who drop out of high school fare worse in many aspects of life. We analyze the relationship between dropping out of high school and the probability of contracting a sexually transmitted infection (STI). Previous studies on the relationship between dropout status and sexual outcomes have not empirically addressed unobserved heterogeneity at the individual level. Using fixed effects estimators, we find evidence supporting a positive relationship between dropping out of high school and the risk of contracting an STI for females. Furthermore, we present evidence that illustrates differences between the romantic partners of dropouts versus enrolled students. These differences suggest that female dropouts may be more susceptible to contracting STIs because they partner with significantly different types of people than do nondropouts. Our results point to a previously undocumented benefit of encouraging those at risk of dropping out to stay in school longer. 相似文献

This paper assesses the effectiveness of traded turnover, Amihud (2002) and Liu (2006) metrics in measuring illiquidity, as used in a multifactor CAPM. The performance of this model is contrasted using a unique sample from Japan’s regional stock exchanges, namely Sapporo, Nagoya, Fukuoka, Osaka and Tokyo. The evidence suggests that size effects are important in Tokyo, liquidity plays a more important role in the conditional modelling of returns particularly in the smaller markets of Sapporo, Fukuoka and Nagoya where costs of equity are highest. 相似文献

This study examines various claims that in the U.S., international trade has contributed to a loss of manufacturing base, an increased gap between unskilled and skilled wages, lower employment, and a loss of productivity. Cointegration tests indicate that in the long run and at the macro level, the ratio of trade to output and FDI to output are correlated with the manufacturing share of output, the ratio of unskilled to skilled wages, labor productivity, and the employment rate. However, Granger causality tests reveal that, with one exception, causation does not run from trade to the domestic variables, the only exception being that FDI Granger causes productivity. When the focus is shifted to the manufacturing sector, the results support the proposition that openness to trade has had adverse effects on this sector.A slightly different version of this paper was presented at the Fifty-sixth International Atlantic Economic Conference, October 16–19, 2003 in Quebec City, Canada. The research reported in this paper is partially funded by a grant from the Institute for Global Economic Affairs at Marquette University. 相似文献

I use satellite imagery on night‐time lights to measure growth across states and local government areas in Nigeria since the return of democracy in 1999. The data suggest that states in southern Nigeria have grown faster on average than states in the north. Using the Ordinary Least Squares, I estimate a relationship between change in night lights and real gross domestic product (GDP) growth in Africa and use the coefficients to estimate GDP growth for states and local government areas in Nigeria over the period. Finally, I evaluate the effects of violence on growth in Plateau, Yobe and Borno states. I find that the crisis in Plateau state has resulted in slower growth compared with other states in the region. I also show that Yobe and Borno states had performed worse than other states in the north even before the outbreak of violence related to the Boko Haram sect. 相似文献

Designing Agricultural Technology for African Women Farmers: Lessons from 25 Years of Experience 总被引:3,自引:0,他引:3
African women farmers are less likely than men to adopt improved crop varieties and management systems. This paper addresses two issues: How does gender affect technology adoption among African farmers? How does the introduction of new technologies affect women's well-being? Three conclusions come out of an extensive and critical review of the literature. First, African households are complex and heterogeneous. Second, gender roles within African households and communities cannot be simply summarized. Third, gender roles and responsibilities are dynamic; they respond to changing economic circumstances. The paper demonstrates the complexity and importance of efforts to design interventions for African women. 相似文献

Most studies have reported non negligible improvements for China in terms of poverty during the last three decades. However, this result is potentially hampered by two limitations. First, it may be contingent to the specific choices made regarding the poverty line and the poverty indices used for the analysis. As a consequence, it may collapse if one uses alternative poverty lines or poverty measures. Second, it results from a focus on the sole monetary aspects of poverty. As income does not cover all facets of well-being and since the relationship between these two concepts are quite fuzzy, it may be worth using a broader view of well-being, hence opting for a multidimensional approach of poverty analysis. In the present paper, these two issues are addressed using multidimensional stochastic dominance procedures on the joint distribution of income, education and health in seven Chinese provinces. 相似文献
