We estimate an aggregate production function with constant elasticity of substitution between energy and a capital/labor composite using U.S. data. The implied measure of energy-saving technical change appears to respond strongly to the oil-price shocks in the 1970s and has a negative medium-run...

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...

Three funds are necessary to manage an oil windfall: intergenerational, liquidity and investment funds. The optimal liquidity fund is bigger if the windfall lasts longer and oil price volatility, prudence and the GDP share of oil rents are high and productivity growth is low. We apply our theory...

We build a two-sector dynamic general equilibrium model with one-sided substitutability between fossil carbon and biocarbon. One shock only, the discovery of the technology to use fossil fuels, leads to a transition from an inital pre-industrial phase to three following phases: a pure fossil...

Many resource-rich countries have poor economic performance and suffer from negative genuine saving rates, especially if they have many rival factions and badly functioning legal systems. We attempt to shed light on these stylized facts by analyzing a power struggle about the control of natural...

This paper investigates the impact of twentieth-century European colonization on African countries. We find that colonization mattered for growth. The following had some beneficial growth effects: being a dependency rather than a colony; being a colony of France or the United Kingdom rather than...

This paper addresses two basic issues related to technological innovation and climate stabilisation objectives: i) Can innovation policies be effective in stabilising greenhouse gas concentrations? ii) To what extent can innovation policies complement carbon pricing (taxes or permit trading) and...

Countries with substantial revenues from renewable resources face a complex range of revenue management issues. What is the optimal time profile of consumption from the revenue, and how much should be saved? Should saving be invested in foreign funds or in the domestic economy? How does...

Cross-country evidence is presented on resource dependence and the link between volatility and growth. First, growth depends negatively on volatility of unanticipated output growth independent of initial income per capita, the average investment share, initial human capital, trade openness, the...

Carbon dioxide emissions may cause global warming. But own emissions have negligible effects for a small nation, which may thus regard carbon taxes as distortionary. Such taxes may have other effects, however. When research and development (R&D) has positive external effects, carbon taxes may...
