We estimate the impact of Malawi's Farm Input Subsidy Programme using an economywide approach. We find potentially substantial net benefits with indirect benefits accounting for about two-fifths of total benefits. Due to these indirect benefits, the cut-off at which lower fertilizer yield...

Prioritizing public investments requires information on relative returns that are difficult to derive from disparate evaluation studies. This paper presents a 'hybrid' approach that combines ex post evaluation data with an economy-wide model for experimenting ex ante with alternative investment...

South Africa is considering introducing carbon taxes to reduce greenhouse gas emissions. We evaluate potential impacts using a dynamic economy-wide model linked to an energy sector model. Simulation results indicate that a phased-in carbon tax that reaches US$30 per ton of CO2 by 2022 achieves...

Climate change may damage road infrastructure to the potential detriment of economic growth, particularly in developing countries. To quantitatively assess climate change's consequences, we construct a climate-infrastructure model based on stressor-response relationships and link this to a...

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...

We apply a probabilistic approach to the evaluation of climate change impacts in the Zambeze River Valley. The economic modeling relies on an economywide modeling approach. Taking a distribution of shocks as inputs, we create hybrid frequency distributions of the potential economic impacts of...

Malawi confronts a development imperative in a context of rising temperatures and deep uncertainty about precipitation trends. We evaluate the implications of climate change for overall growth and development prospects to 2050. We focus on three impact channels: agriculture, road infrastructure,...

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...

We link a bottom-up energy sector model to a recursive dynamic computable general equilibrium model of South Africa in order to examine two of the country's main energy policy considerations: (i) the introduction of a carbon tax and (ii) liberalization of import supply restrictions in order to...

This study represents the first attempt at an integrated approach to assessing the potential impacts of climate change on the national economy of South Africa via a number of (but not necessarily all) impact channels. The study focuses on outcomes by about 2050. The results show the multiple...
