An Empirical Study of Suicide Terrorism: A Global Analysis

This paper provides the first venue‐based empirical investigation of the number and lethality of suicide terrorist attacks on a global scale. For 1998–2010, we assemble a data set of 2448 suicide terrorist incidents, drawn from the three main terrorist event databases, i.e., International Terrorism: Attributes of Terrorist Events (ITERATE), the Global Terrorism Database (GTD), and RAND. Our data set distinguishes between domestic and transnational suicide terrorist missions. For the quantity of suicide terrorism, we apply zero‐inflated negative binomial panel (country‐year) estimation for country‐specific variables and negative binomial panel estimation for attack‐specific variables. We also present linear regression panel estimations for the impact of suicide terrorism in terms of casualties per attack. Economic, political, and military variables, at times, differentially influenced the two kinds of suicide terrorism. A host of policy conclusions are drawn from the empirical findings.     

Health Expenditures and Health Outcomes in Africa*

Abstract: This paper provides econometric evidence linking African countries’ per capita total as well as government health expenditures and per capita income to two health outcomes: infant mortality and under‐five mortality. This relationship is examined using data from 47 African countries between 1999 and 2004. Health expenditures have a statistically significant negative effect on infant and under‐five mortality rates. The magnitude of our elasticity estimates are in consonance to those reported in the literature. For African countries, our results imply that total health expenditures (as well as the public component) are certainly important contributors to health outcomes. In addition, we find that both infant and under‐five mortality are positively and significantly associated with sub‐Saharan Africa. The reverse is true for North Africa. While ethnolinguistic fractionalization and HIV prevalence positively and significantly affect the health outcomes, higher numbers of physicians and female literacy significantly reduce these health outcomes. These results have important implications for attaining the targets envisioned by the Millennium Development Goals. The data implications are also discussed.     

Accounting for Gender Equality in Secondary School Enrollment in Africa

In addition to analyzing the characteristics of gender equality in secondary education enrollment in Africa, this paper empirically studies the key drivers of gender equality in secondary education enrollment, using cross‐sectional time series data from 1970 to 2010. Our results show that the coefficient associated with the level of real GDP per capita is positive and statistically significant in both the overall Africa sample and in the sub‐Saharan and North African samples. But the quadratic term of real GDP per capita is negative in sign and significant in the overall Africa and sub‐Saharan African estimates. These provide evidence of a hump‐shaped relationship between real GDP per capita and gender equality in secondary education enrollment in Africa. Our results also suggest that higher share of female teachers in secondary schools, increased democracy (at a decreasing rate), higher female share of the labor force, Christian dominance in a country, higher domestic investment rate, and being an oil‐exporting country increase gender equality in secondary education enrollment in the continent. However, higher population growth tends to lower it. The policy implications and lessons of these results are discussed.     

Old Wine in a New Bottle: Growth Convergence Dynamics in the EU

In this paper, we explore convergence of real per capita output across the European Union (EU) countries, as well as the transitional behavior of possible underlying factors that are responsible for any convergence or divergence pattern. The new panel convergence methodology developed by Phillips and Sul (2007) is employed in a production function growth accounting approach and data from the Total Economy Database and the Total Economy Growth Accounting Database. The empirical findings suggest that the EU countries form two distinct convergent clubs, exhibiting considerable heterogeneity in the underlying growth factors. These findings should help policy makers in designing appropriate growth-oriented programs as well as in setting priorities in their implementation.     

When Does Economic Growth Reduce Poverty and Strengthen the Middle Class? A State-Level,Sector-Specific Analysis of Peru

Using novel state-level data of Peru from 1997 to 2010, we investigate how growth in different sectors affects poverty rates and the middle class. Our results indicate that only the manufacturing sector seems to robustly decrease poverty. Growth in the service sector emerges as a meaningful predictor of a rising middle class. Allowing for regional differences, we find substantial variation across the 25 Peruvian states with large shifts in magnitudes, signs, and statistical importance. Beyond the immediate implications for Peru, these findings highlight the importance of analyzing the link between economic performance and poverty rates on a subnational level. Policy implications are likely to differ substantially, depending on the source of economic growth and regional particularities.     

Economic Convergence in the African Continent: Closing the Gap

The paper attempts to analyse the conditional β‐convergence and its sources for 32 African countries over the period 1960‐2008. The augmented Solow model with both gross domestic product (GDP) per worker and per capita income is estimated using the dynamic system generalized methods of moments (GMM) technique with the panel data. This is the first study on the sources of conditional β‐convergence for African countries. According to the results of the augmented Solow model, income convergence rates are lower than those of GDP per worker. Moreover, total factor productivity convergence, human capital convergence and capital labour convergence are contributing towards the convergence of GDP per worker in Africa. This means that growth in the poorest African countries is being augmented by “catch‐up factor,” which is good news for them. However, convergence in terms of GDP per worker is not being fully translated into income per capita convergence. The demographic structure in the African continent with its record of persistent population growth has played an important role in lowering the income convergence of its countries.     

Genuine Wealth Per Capita as a Measure of Sustainability and the Negative Impact of Corruption on Sustainable Growth in Sub‐Sahara Africa

In this paper, we argue that the answer to the question of whether the impact of corruption on development is homogenous, is no. Our optimism rest on how development may be conceptualised. When equated to a narrow measure in economic‐wise which fundamentally ignores critical issues, then there is a possibility the outlook could be positive. But when conceptualised using a broad‐based approach such as sustainable development, then the outlook could be negative. We assess a panel of 22 economies in Sub‐Sahara Africa with the most recent dataset (1996–2013) from the World Bank and other reputable agencies. Our finding is quite robust. It holds in pooled OLS, Fixed effects and GMM within IV settings; and it also holds for different measures of institutions and different measures of development using growth per capita GDP and genuine wealth per capita, respectively. Taking stock of major policy blue‐prints of selected countries in the region on the fight against corruption, we are able to point out that institutions play important role in insulating citizens against the devastation caused by corruption. Overall, through this comparison, we are able to signal that both incidental and systematic corruption poses a long‐term threat to sustainable development.

Terrorism and its Determinants in the Sub‐Saharan Africa Region: Some New Insights

Terrorism is undesirable as it adversely affects the economic development of countries. This study explores the determinants of terrorism in 29 countries of sub‐Saharan Africa (SSA). The data is extracted from reliable sources spanning over 2005 to 2016. Econometric techniques relevant for panel data that control for unobserved heterogeneity (fixed effects) and endogeneity (generalized method of moment) are employed to estimate the specified models. The results indicated that low growth in per capita incomes along with political instability are the main driving forces responsible for terrorism. Similarly, military expenditures are influencing terrorism positively whereas corruption has impacted terrorism negatively in the SSA region. Further, the growth of both physical as well as human capital reduces terrorism. The paper suggests that the region should take appropriate steps for increasing income of the population, education and capital stock, along with ensuring political stability to eradicate terrorism from the region.     

Budget Structure and Pollution Control： A Cross-country Analysis and Implications for China

In the published literature, the differences in environmental performance across countries are typically explained using the Environmental Kuznets Curve. The Environmental Kuznets Curve states that pollution initially increases with economic growth. Once GDP per capita reaches a certain level, the relationship reverses. In the present paper, we provide an alternative hypothesis, where budget structure plays an important role in explaining the variations in pollution across the world.＂ the lower the business-related taxes as a share of total tax revenue, the higher the property tax in total tax revenue and the higher the ratio of public health expenditure in total expenditure, then the stronger the incentive of pollution control and the lower the pollution level. Our empirical findings reveal that the budget structure does have an important impact on pollution control. The policy implication of this research is that effective control of environmental pollution requires changes in tax structure and expenditure assignment. This research has important policy implications for China ＂s tax system reform and pollution control efforts.     

Basic human needs: The plateau curve

The satisfaction of basic human needs in developing countries follows a nonlinear curve relative to per capita income, asymptotically approaching a limiting level. Within this general relationship, some countries are more ‘efficient’ than others in improving basic needs at lower per capita income levels. Infant mortality rates in 116 countries, from 1950 to 1980, are analyzed to identify factors affecting a country's efficiency in reaching infant mortality targets relative to its Gross Domestic Product per capita. The determinants of efficiency include export structure, internal distribution, late development and access to education. Implications for development policy are discussed.     

Are Real GDP Levels Stationary in African Countries?

In this study, we apply flexible Fourier stationary unit root test proposed by Enders and Lee (2012) to assess the non‐stationary properties of the per capita real gross domestic product (GDP) for 32 African countries. We find that Fourier stationary unit root test has higher power than linear method if the true data‐generating process of per capita real GDP is in fact a stationary nonlinear process of an unknown form with structural change using the low frequency components. We investigate the stationarity of per capita real GDP from the nonlinear point of view and provide robust evidence that clearly indicates that real output is well characterised by a nonlinear, mean‐reverting process, namely Benin, Botswana, Burundi, Cameroon, Senegal, Sierra Leone and South Africa. Our evidence points that these seven countries are nonlinear stationary, implying that per capita real GDP follows a steady rate of growth, and policy innovations then have temporary effects. These results have important policy implications for African countries.

Twentieth Century Shocks, Trends and Cycles in Industrialized Nations

Using annual data on real Gross Domestic Product per capita of seventeen industrialized nations in the twentieth century the empirical relevance of shocks, trends and cycles is investigated. A class of neural network models is specified as an extension of the class of vector autoregressive models in order to capture complex data patterns for different countries and subperiods. Empirical evidence indicates nonlinear positive trends in the levels of real GDP per capita, time varying growth rates, switching behavior of individual countries with respect to their position in the distribution of real GDP per capita levels over time. Such evidence presents challenges for economic modelling, forecasting and policy analysis for the long run.     

Do International Remittances Affect Poverty in Africa?*

Abstract: International remittances flowing into developing countries are attracting increasing attention because of their rising volume and their impact on recipient countries. This paper uses a panel data set on poverty and international remittances for African countries to examine the impact of international remittances on poverty reduction in 33 African countries over the period 1990–2005. We find that international remittances—defined as the share of remittances in country GDP—reduce the level, depth, and severity of poverty in Africa. But the size of the poverty reduction depends on how poverty is being measured. After instrumenting for the possible endogeneity of international remittances, we find that a 10 percent increase in official international remittances as a share of GDP leads to a 2.9 percent decline in the poverty headcount or the share of people living in poverty. Also, the more sensitive poverty measures—the poverty gap (poverty depth) and squared poverty gap (poverty severity)—suggest that international remittances will have a similar impact on poverty reduction. The point estimates for the poverty gap and squared poverty gap suggest that a 10 percent increase in the share of international remittances will lead to a 2.9 percent and 2.8 percent decline, respectively, in the depth and severity of poverty in African countries. Regardless of the measure of poverty used as the dependent variable, income inequality (Gini index) has a positive and significant coefficient, indicating that greater inequality is associated with higher poverty in African countries, much in conformity with the literature. Similar results were obtained for trade openness. In the same vein, per capita income has a negative and significant effect on each measure of poverty used in the study. Our results also show that inflation rates positively and significantly affect poverty incidence, depth and severity in Africa. In all three poverty measures, the dummy variable for sub‐Saharan Africa is strongly positive, and strongly negative for North Africa. The policy implications of these results are discussed.

Unequal access to education and income distribution

Summary This paper attempts a new specification of the education variable in accounting for differences in income distribution in a cross-sectional analysis of 49 countries. The specification refers to the steepness of the educational pyramid, as measured by the coefficient of variation of enrolments within a given country. This variable alone explains 23 per cent of income inequality across countries (as measured by the Gini coefficient), while in the presence of it the traditional (catch-all) per capita income variable becomes insignificant.This finding indicates the importance of the supply side in relative income determination. It is also suggestive that a policy aiming at equalisation of access to the different levels of education might help in reducing income inequality.I would like to thank Arnold Anderson, Mary Jean Bowman, Jan Tinbergen and Peter Wiles for commenting on an earlier draft of this paper.     

Product price differences across countries: determinants and effects

A substantial part of international differences in prices of individual products, both goods and services, can be explained by differences in per capita income, wage compression, or low wage dispersion among low-wage workers, and exchange rate fluctuations. Higher per capita income is associated with higher prices and higher wage dispersion with lower prices. The effects of higher income and wage dispersion are moderated for the more tradable products. The effects of wage dispersion, on the other hand, are magnified for the more labor-intensive products, particularly low-skill services. The differences in prices across countries are reflected in differences in the composition of consumption. Countries in which prices of labor-intensive services are very high, such as the Nordic countries, consume much less of them. For some services, the shares of GDP consumed in high-price countries are less than 20% of the shares in low-price countries. Since these are services of very low tradability, the low consumption levels of these services imply low employment in them.     

An empirical assessment of the relationship between competition policy and investment

The relationship between competition policy and investment is empirically examined. Empirical findings suggest that increasing market competition has a positive and robust impact on the share of total investment in GDP per capita. Developing countries enjoy benefits from competition legislation efficiency improvement, whereas the reduction of government anti-competitive price control intervention enhances the good investment environment in developed countries. In relation to the potential impacts of ASEAN competition policies, if ASEAN-4 countries (Indonesia, Malaysia, Philippines, and Thailand) become as competitive as Singapore, the investment shares are expected to increase to approximately 2–4%. Further, foreign direct investment inflows from the 30 OECD countries are expected to increase roughly 0.6–1.2%.
