We investigate the marginal productivity of investment across countries. The aim is to estimate the return on investments financed by foreign aid and by domestic resource mobilization, using aggregate data. Both returns are expected to vary across countries and time. Consequently we develop a...

Average adult height is a physical measure of the biological standard of living of a population. While the biological and economic standards of living of a population are very different concepts, they are linked and may empirically move together. If this is so, then cohort heights can also be...

Since 1994, a great deal has been accomplished. We argue that poverty reduction was temporarily sidelined in the 2000s. A series of shocks, especially the fuel and food price crisis of 2008, combined with poor productivity growth in agriculture and a weather shock, undermined progress in...

This paper uses normalized constant elasticity of substitution production functions to estimate the elasticity of substitution and labour-augmenting technical change in South Africa over the period 1994-2012. We find elasticities of 0.6-0.9 and positive labour-augmenting technical change, which...

The structure of the Nigerian economy is typical of an underdeveloped country. The primary sector, in particular, the oil and gas sector, dominates the gross domestic product accounting for over 95 per cent of export earnings and about 85 per cent of government revenue between 2011 and 2012. The...

This paper re-examines the determinants and consequences of redistribution in light of improved data and methods relative to earlier literature. In particular, we use the latest version of the UNU-WIDER' Income Inequality Database to have the best available estimates of both pre- and...

Over the past sixty years, most Asian countries have undergone relatively rapid agricultural transformations that helped jumpstart broader economic development. However, the changes have differed markedly in nature and speed across countries of the region. In much of East and Southeast Asia, the...

This study examines the relationship between growth and employment in Nigeria to gain insights into the country's paradox of high economic growth alongside rising poverty and inequality. The methodology adopted is the Shapley decomposition approach, complemented with econometric estimation of...

This paper examines the connections of structural change and economic openness to labour productivity growth using a panel data set of 41 countries in sub-Saharan Africa for the period 1991-2015. A dynamic panel model of cross-country productivity growth is estimated using the least squares with...

This paper explores the contribution of structural change and the skill upgrading of the labour force to productivity. Our growth decomposition based on an original database we built for Tunisia and Turkey shows that productivity is mainly explained by intra-industry changes during the import...
