We analyze a power struggle about the control of natural resources where competing factions in society have a private stock of financial assets and a common stock of natural resources with inadequately defined private property rights. We solve a dynamic common-pool problem and obtain political...

In this paper we examine the claim that natural resources invite civil conflict, and challenge the main stylized facts in this literature. We find that the conventional measure of resource dependence is endogenous with respect to conflict, and that instrumenting for dependence implies that it is...

What are the effects of regional integration and other trade policy measures in regions such as Central Asia or the Great Lakes Region of Africa where countries are remote with poor access to the outside world and where foreign exchange earnings come largely from natural resource based exports?...

The effects of stochastic future oil prices on optimal oil extraction paths and optimal tax, spending and government debt policies are analyzed when demand for oil is linear and preferences quadratic. Without prudence, optimal oil extraction is governed by the Hotelling rule and optimal...

What part of the rising trend in the oil price is driven by structural transformation in China and India? Will continued structural transformation in these countries result in a permanently higher oil price? I identify an inverted-U shaped relationship in the data between aggregate oil intensity...

Brock and Taylor (2010) argue that the Environmental Kuznets Curve (EKC) - a hump shaped relationship between emissions and income per capita - is driven by falling GDP growth rates associated with Solow type convergence. I test the importance of their mechanism as a driver of emissions by...

There have been important studies of overall income inequality and of poverty in South Africa. In this paper, we approach the subject from a different direction: the extent and evolution of top incomes. We present estimates of the shares in total income of groups such as the top 1 per cent and...

This paper addresses the efficient management of natural resource revenues in capital-scarce developing economies. We depart from usual prescriptions based on the permanent income hypothesis, since for capital-scarce countries it is preferable to invest domestically. Since revenue streams are...

The Green Paradox states that, in the absence of a tax on CO2 emissions, subsidizing a renewable backstop such as solar or wind energy brings forward the date at which fossil fuels become exhausted and consequently global warming is aggravated. We shed light on this issue by solving a model of...

We analyse optimal carbon taxes, optimal redistribution within and between non-overlapping generations, and optimal spending levels on climate abatement and adaptation. A positive probability of unexpected large increases in CO2 emissions results in a lower discount rate for global warming...
