We investigate how urban concentration and urbanization affect economic growth in developing countries. Using semi-parametric estimation techniques on a cross-country panel of 39 countries for the years 1960-1990 we discover a U-shaped relationship for urban concentration. This suggests the...

This paper provides empirical evidence that there is no absolute convergence between the GDP per capita of the developing countries since 1950. Relying upon recent econometric methodologies (nonstationary long-memory models, wavelet models and time-varying factor representation models), we show...

During recent years, new doubts about the effectiveness of international aid have emerged. One of the arguments employed to justify this sceptical view is that aid can hinder tax effort in developing countries. Nevertheless, empirical research on the aid-tax nexus is inconclusive and it shows...

The link between foreign aid and economic growth remains a controversial issue in the literature, and a large share of the disagreement could be explained by differences in the data employed. Using GDP data from three different versions of the Penn World Table and the World Development...

There has been a recent resurgence of interest in the relationships between income inequality and growth, trade policy and growth, and growth and poverty. We contribute to this literature by exploring the relationships between inequality, trade liberalisation, growth and poverty in a sample of...

Foreign aid inflows have grown significantly in the post-war period. Many studies have tried to assess the effectiveness of aid at the micro- and macro-level. While micro-evaluations have found that in most cases aid "works", those at the macro-level are ambiguous. This paper assesses the impact...

This paper contributes to the literature on aid and economic growth. We posit that it is not the level of aid flows per se but the stability of such flows that determines the impact of aid on economic growth. Three measures of aid instability are employed. One is a simple deviation from trend,...

This paper contributes to the literature on FDI and economic growth. We deviate from previous studies by introducing measures of the volatility of FDI inflows. As introduced into the model, these are predicted to have a negative effect on growth. We estimate the standard model using...
