We study whether the spatial distribution of natural resources across different ethnic groups within countries impede spatial inequality, national economic performance, and the incidence of armed conflict. By providing a theoretical rent-seeking model and analysing a set of geocoded data for...

Africa’s interior-to-coast roads are well suited to export natural resources, but not to support regional trade. Are they the optimal response to geography and comparative advantage, or the result of suboptimal political distortions? We investigate the political determinants of road paving in...

Rational choice theories assume that voters accurately assess the outcomes of policies. However, many important policies—such as regulating prices and introducing Pigouvian taxation—yield outcomes through indirect or equilibrium effects that may differ from their direct effects. Citizens may...

Between 1997 and 2014, US corn, soybean and cotton production almost fully converted to genetically modified crops. Starting around 2007, improved tight oil and shale gas technologies turned the declining US fossil fuel production into a booming industry. We study the effects of these two...

This paper studies the properties of second-best optimal policy in a standard general equilibrium model of growth augmented with renewable natural resources. The government chooses its policy instruments (the income tax rate and the allocation of collected tax revenues between public investment...

Because excessive specialization can be risky, diversification matters for sustainable development. A case study of Madagascar, this paper begins by briefly discussing economic and institutional diversification and presenting a simple model of production possibilities to illuminate the possible...

The need to absorb windfalls gains and manage them appropriately has been discussed extensively by academics and policy makers alike. We explore the role of the financial sector in intermediating these windfalls. Controlling for the level of financial development, inflation, GDP growth and...

This note generalizes the Solow-Stiglitz efficiency condition for natural resources to the problem of fossil fuel extraction with a greenhouse effect. The generalized optimality condition suggests that the greenhouse effect implies overextraction in the sense of leaving future generations a...

Judged by the principle of intertemporal Pareto optimality, insecure property rights and the greenhouse effect both imply overly rapid extraction of fossil carbon resources. A gradual expansion of demand-reducing public policies - such as increasing ad-valorem taxes on carbon consumption or...

For a country fractionalized in competing factions, each owning part of the stock of natural exhaustible resources, or with insecure property rights, we analyze how resources are transformed into productive capital to sustain consumption. We allow property rights to improve as the country...
