Eleven percent of the Malawian population is HIV infected. Eighteen percent of sexual encounters are casual. A condom is used one quarter of the time. A choice-theoretic general equilibrium search model is constructed to analyze the Malawian epidemic. In the developed framework, people select...

Output per worker is lower in poor countries than in rich countries, and relatively more so in the agricultural sector. Sorting of heterogeneous workers can contribute to explain this fact if comparative and absolute advantage are aligned in agriculture, implying that average productivity in...

This article seeks to explain Africa's current quot;period of unparalleled economic success,quot; following decades of economic stagnation. Using newly available data, we investigate whether international commodity price increases (our quot;metalsquot; hypothesis) or policy reforms (our...

How can foreign aid support economic growth in Africa? This paper presents a geographically indexed general equilibrium model that enables green revolution-focused macroeconomic analysis in low-income African settings. The model is flexible to parameterization and highlights the role of...

There is controversy about whether geography matters mainly because of its contemporaneous impact on economic outcomes or because of its interaction with historical events. Looking at terrain ruggedness, we are able to estimate the importance of these two channels. Because rugged terrain hinders...

Despite the evolving literature on the development benefits of mobile phones, we still know very little about factors that influence their adoption. Using twenty five policy variables, we investigate determinants of mobile phone penetration in 49 Sub-Saharan African countries with data for the...

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...
