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...

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 optimal reaction to a pending climate catastrophe is to accumulate capital to be better prepared for the disaster and levy a carbon tax to reduce the risk of the hazard by curbing global warming. The optimal carbon tax consists of the present value of marginal damages, the non-marginal...

The optimal reaction to a productivity shock which becomes more imminent with global warming is to price carbon (proportional to the marginal hazard of a catastrophe) to curb the risk of climate change, but also to accumulate precautionary capital to facilitate smoothing of consumption and curb...
