In this paper I compute implementable ?scal rules for a small open economy whose treasury is dependent on oil revenues and whose oil sector is shrinking. I model production in the oil and non oil sector and I analyze the e¤ects of implementing di¤erent sustainable ?scal rules in the context of...

Unilateral, second-best carbon taxes are analysed in a two-period, two-country model with international trade in final goods, oil and bonds. The increase in oil demand and acceleration of global warming resulting from a future carbon tax are large if the price elasticities of oil demand are...

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...

The Green Paradox states thata gradually more ambitious climate policy such as a renewables subsidy or an anticipated carbon tax induces fossil fuel owners to extract more rapidly and accelerate global warming However, if extraction becomes more costly as reserves are depleted, such policies...

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...

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...

Public investment and subsidies are typically inefficient but in the GCC these are crucial engines of growth. Subsidies are also used to redistribute oil windfalls in the region, and the problem of a government that wants to 'distribute' oil money is a problem fully symmetric to the one analyzed...

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...

Resource-rich countries have tended to be autocratic and also have tended to use their resource wealth badly. The neoconservative agenda of promoting democratization in resource-rich countries thus offers the hopeful prospect of a better use of their economic opportunities. This paper examines...
