South Africa is currently confronting an HIV|AIDS crisis. HIV prevalence in the population is currently estimated at about 13 per cent with that number projected to increase over the next five years or so. Given the massive scale of the problem and the concentration of effects on adults of prime...

This paper considers different approaches to modelling the economic impact of the COVID-19 pandemic/lockdown shocks. We review different modelling strategies and argue that, given the nature of the bottom-up recession caused by the pandemic/lockdowns, simulation models of the shocks should be...

Controversy over the aggregate impact of foreign aid has focused on reduced form estimates of the aid-growth link. The causal chain, through which aid affects developmental outcomes including growth, has received much less attention. We address this gap by: (i) specifying a structural model of...

Long-run economic development in Ghana is potentially vulnerable to anthropogenic climate change given the country's dependence on rainfed agriculture, hydropower, and unpaved rural roads. We use a computable general equilibrium model, informed by detailed sector studies, to estimate the...

This paper confirms recent evidence of a positive impact of aid on growth and widens the scope of evaluation to a range of outcomes including proximate sources of growth (e.g., physical and human capital), indicators of social welfare (e.g., poverty and infant mortality), and measures of...

Unlike existing studies, we adopt a multi-sectoral approach and consider the full range of climate projections. Biophysical damages are translated into economic costs using a dynamic economywide model. Our results for Vietnam indicate that the negative impacts on agriculture and roads are...
