Oil exporters typically do not consider below-ground assets when allocating their sovereign wealth fund portfolios, and ignore above-ground assets when extracting oil. We present a unified framework for considering both. Subsoil oil should alter a fund’s portfolio through additional leverage...

One of the most important developments in international finance and resource economics in the past twenty years is the rapid and widespread emergence of the $6 trillion sovereign wealth fund industry. Oil exporters typically ignore below-ground assets when allocating these funds, and ignore...

A new and extensive panel of outward nonresource and resource FDI is used to investigate the effect of natural resources on the different components of FDI. Our main findings are as follows. First, for countries which were not a resource producer before, a resource discovery causes nonresource...

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...

Industria imports oil, produces final goods and wishes to mitigate global warming. Oilrabia exports oil and buys final goods from the other country. Industria uses the carbon tax to impose an import tariff on oil and steal some of Oilrabia’s scarcity rent. Conversely, Oilrabia has monopoly...

We use the Euler equation to put forward a back-on-the-envelope rule for the global carbon tax based on a two-box carbon cycle with temperature lag, and a constant elasticity of marginal damages with respect to GDP. This tax falls with time impatience and intergenerational inequality aversion...

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 nature of oil demand influences the oil extraction rate and hence has implications for both the timing of oil exhaustion and optimal climate policy. We analyse what role oil demand specification plays in strategic interactions b between an oil-importing country producing final goods and...

A rapidly rising carbon tax leads to faster extraction of fossil fuels and accelerates global warming. We analyze how general equilibrium effects operating through the international capital market affect this Green Paradox. In a two-region, two-period world with identical homothetic preferences...

The optimal social cost of carbon is in general equilibrium proportional to GDP if utility is logarithmic, production is Cobb-Douglas, depreciation is 100% every period, climate damages as fraction of production decline exponentially with the stock of atmospheric carbon, and fossil fuel...
