The principles of how best to manage the various components of national wealth are outlined, where the permanent income hypothesis, the Hotelling rule and the Hartwick rule play a prominent role. As far as managing natural resource wealth is concerned, a case is made to use an intergenerational...

A classroom model of global warming, fossil fuel depletion and the optimal carbon tax is formulated and calibrated. It features iso-elastic fossil fuel demand, stock-dependent fossil fuel extraction costs, an exogenous interest rate and no decay of the atmospheric stock of carbon. The optimal...

An analytical framework predicts that, in response to an exogenous increase in resourcebased government revenue, a benevolent government will partially substitute away from taxing income, increase spending and save. Forty-two years of U.S. state-level data are consistent with this theory....

The optimal reaction to a pending climate catastrophe is to accumulate capital to be better prepared for the disaster and levy a carbon tax to reduce the risk of the hazard by curbing global warming. The optimal carbon tax consists of the present value of marginal damages, the non-marginal...

Optimal climate policy should act in a precautionary fashion to deal with tipping points that occur at some future random moment. The optimal carbon tax should include an additional component on top of the conventional present discounted value of marginal global warming damages. This component...

Many developing countries periodically face large adverse shocks to their economies.  We study two distinct types of such shocks - large declines in the price of a country's commodity exports and severe natural disasters - , both of which have occurred frequently in the recent past. ...

The global response to a catastrophic shock to productivity which becomes more imminent with global warming is to have carbon taxes to curb the risk of a calamity and to accumulate precautionary capital to facilitate smoothing of consumption.  Our multi-region model of growth and climate change...

In partial equilibrium a rapidly rising carbon tax encourages oil producers to extract fossil fuels more quickly, giving rise to the Green Paradox. General equilibrium analysis for a closed economy shows that a rapidly rising carbon tax negatively affects the interest rate, which tends to weaken...

This paper answers two questions: "What impact have natural resources had on the spread of the HIV/AIDS epidemic so far?" and "What role can natural resource rents play in order to finance the long-run response to HIV/AIDS?"  Using a panel dataset, de Soysa and Gizelis (2013) provided evidence...

This paper studies how capital-scarce countries should manage volatile resource income.  Existing literature recommends that capital-scarce countries invest domestically, but that volatile resource income should be saved in a foreign sovereign wealth fund.  I reconcile these by combining a...
