This paper uses panel data for 116 countries over the period 1995-2016 to investigate the heterogeneity of the debt-growth nexus across countries and the factors underlying it. In the first step, the grouped fixed effects (GFE) estimator proposed by Bonhomme and Manresa (2015) is used to...

This paper uses international migration data and climate variables in a multi-country setting to investigate the extent to which international migration can be explained by changes in the local climate and whether this relationship varies between groups of countries. Moreover, the primary focus...

The beginning rise in obesity prevalence rates in South Africa was first noticed already in the early 1990s. Since then, several articles have discussed how the nutrition transition has affected people’s body weights in the country. This article is the first one that uses longitudinal data...

This paper presents a theoretical gravity model of trade in which foreign aid is considered as a transfer instead of being part of the trade cost, as it has been previously done in the related literature. We argue that the usual specification leads to invalid out-of-sample predictions, biased...

This dissertation includes three empirical essays on development economics and one on the economics of education. The first essay (co-authored by Stephan Klasen) is a contribution to the debate surrounding the Millennium Development Goals (MDGs) and the on-going debate about what international...

We examine the impact of two important non-tariff measures presumed to simultaneously affect firms’ decisions to export to the European Union (EU). As a novelty to the literature, we analyse the impacts of EU pesticide standards on African exports alongside a complementary non-tariff measure...

This paper presents a review of recent studies that estimate the trade effects of foreign aid. It also provides new results obtained using panel data techniques to estimate the direct effects of aid on international trade, accounting for countries' participation in free trade agreements, and the...

This study provides a re-examination of the aid-income link based on a panel data set which is downloadable at the Canadian Journal of Economics 45(1), 2012 issue. Longer time series data are available for a group of 58 countries and run from 1960 to 2007. In particular, the study aims at...

Remittances, the part of the migrant's income sent back to their family living in the origin country, have become a critical stepping-stone to economic development for many developing nations. A key factor that causes migrants to use informal channels is the high cost of transferring funds...

In this paper, we examine the extent to which developing countries export more as a result of being officially labelled as an LDC and consequently being eligible for a range of unilateral trade preferences. We estimate a gravity model of trade over the period of 1970 to 2013, in which...
