We document an empirical puzzle for EMS exchange rates during a period in which the bands on these exchanges rates were (almost) credible, i.e. exchange rate distributions are humpshaped rather than U-shaped as predicted by the standard target zone model. We offer an explanation of this puzzle...

Macroeconomic stabilisation and foreign exchange market interventions are inves-tigated within the context of a stochastic small open economy. With money demand shocks a peg is optimal, but with goods demand shocks a nominal income target is best. With supply shocks the optimal degree of...

A democratic society in which the distribution of wealth is unequal elects political parties that are likely to represent the interests of poor people. It is in the interests of the clientele of the resulting governments to attempt to levy inflation taxes in order to erode the real value of debt...

Intergenerational funds smooth expected consumption across generations in face of an oil windfall. Precautionary buffers or liquidity funds cope with oil price volatility and are a politically more acceptable alternative to hedging. The magnitude of these buffers depends on the volatility of oil...

Many oil exporters accumulate large sovereign wealth funds, though their portfolio allocation does not take into account below-ground assets, like oil. Similarly, the above-ground portfolio does not affect the decision to extract oil. This paper shows that subsoil oil wealth should change a...

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...
