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...

Climate change must deal with two market failures, global warming and learning by doing in renewable use. The social optimum requires an aggressive renewables subsidy in the near term and a gradually rising carbon tax which falls in long run. As a result, more renewables are used relative to...

In a calibrated integrated assessment model we investigate the differentia impact of additive and multiplicative damages from climate change for both a socially optimal and a business-as-usual scenario in the market economy within the context of a Ramsey model of economic growth. The sources...

We show how a monopolistic owner of oil reserves responds to a carbon-free substitute becoming available at some uncertain point in the future if demand is isoelaastic and variable extraction costs are zero but upfron exploration investment costs have to be made. Not the arrival of this...

Resource wars can be modeled with two-way regime switch uncertainty and contest success functions. Fighting is more intense if the plitical system is less cohesive, fighting technology is well developed, oil reserves are high and the wage is low. More government stability intensifies resource...

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...

Optimal climate policy is studied in a Ramsey growth model. A developing economy weighs global warming less, hence is more likely to exhaust fossil fuel and exacerbate global warming. The optimal carbon tax is higher for a developed economy. We analyze the optimal time of transition from fossil...

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...

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...

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...
