Robust Estimates of Changes in Poverty and Inequality in Post‐Independence Namibia

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.     

Managing Food Price Instability in Asia: A Macro Food Security Perspective*

The present paper describes the benefits and costs, in qualitative terms, of managing food price instability in Asia in the context of promoting economic growth and poverty reduction to improve food security. The experience of Asian governments in actual practice with price stabilization is discussed in the context of managing an efficient transition to market‐mediated food security. Recent experience in Indonesia, where a sharp increase in rice prices (caused by a ban on rice imports) pushed 4 million people into poverty, provides continued motivation for the analytical story in this paper.     

Institutional Quality and CO2 Emission–Trade Relations: Evidence from Sub‐Saharan Africa

This paper examines the roles of trade, institutional quality and their interactions in explaining carbon dioxide emissions in a panel sample of 40 Sub‐Sahara African countries using the system generalised method of moments. We find that institutional reforms are unequivocally environmental improving. Meanwhile, the impacts of trade on the environment tend to depend on the institutional setting of a country. More specifically, trade openness is harmful to the environment in countries with low institutional quality and beneficial to the environment in countries with high institutional quality. This means that institutional reforms are a perquisite for the countries with low institutional quality to actualise the beneficial environment effect of trade. As for the countries with adequate institutional quality, trade and institutions are reinforcing each other in bringing down pollution. From these results, we conclude that trade openness implemented in a sound institutional setting potentially brings better trade, more growth and better environment.     

The Effects of Remittances on Output per Worker in Sub‐Saharan Africa: A Production Function Approach

This paper uses a production function to examine the channels through which remittances affect output per worker in 31 Sub‐Saharan African countries from 1980 to 2010. Lagged remittances increase physical capital per worker, average years of schooling and total factor productivity, but the effectiveness of remittances varies with the income level of the recipient nation. Although remittances have increased both physical capital and total factor productivity among the upper middle income nations, among the lower middle income, they have increased only the physical capital. Meanwhile a reduction in institutional risk has encouraged investment and efficiency, but its relationship to the effectiveness of remittances has been inconclusive.
