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...

This study addresses the macroeconomic effect of foreign aid on the factors of growth. Specifically, we examine the effects of foreign aid on capital investment (human capital, physical capital) in sub-Saharan Africa. Our methodological approach evaluates the effect of disaggregate aid (aid for...

This paper develops linear estimators for structural and causal parameters in nonparametric,nonseparable models using panel data. These models incorporate unobserved, time-varying, individual heterogeneity, which may be correlated with the regressors. Estimation is based on an approximation of...

Using a panel vector autoregressive model this paper investigates the dynamic and endogeneous contribution of tourism to output based on a sample of 40 African countries for the period 1990 - 2006. Results from the study confirm tourism to be an important ingredient of African development...

The recent financial crisis has rekindled interest in the foreign aid supply behaviour of bilateral donors. Using the latest data covering the period 1960-2009, this paper examines how such behaviour is related to domestic factors. Based on a simple empirical model, a distinction is made between...

This paper investigates whether Southern African Development Community countries that are vulnerable to changes in oil prices could instead substitute oil and petroleum products with biofuels and gas from within the region. A pooled mean group estimator was used to determine the impact of oil...

A substantial amount of aid to developing countries is given to the government, or goes through the budget, meaning it should have an impact on government fiscal behaviour (particularly on government spending). The few existing empirical studies on the effects of aid on government spending...

This survey discusses the recent causal panel data literature. This recent literature has focused on credibly estimating causal effects of binary interventions in settings with longitudinal data, with an emphasis on practical advice for empirical researchers. It pays particular attention to...
