The distributional effects of the minimum wage are analysed in a model where skilled and unskilled labour enter the production function. It is argued that distributional goals are best achieved by letting the labour market clear and achieving redistribution through taxes and transfers.

This paper considers the effects of monetary and fiscal policies in an optimizing model with capital accumulation and finite lives. An increase in monetary growth is no longer superneutral in a money-capital economy, but leads to a reduction in the real interest rate and increases in the capital...

After a brief review of classical, Keynesian, New Classical and New Keynesian theories of macroeconomic policy, we assess whether New Keynesian Economics captures the quintessential features stressed by JM Keynes. Particular attention is paid to Keynesian features omitted in New Keynesian...

This paper analyses and compares the effects of common demand and supply shocks on the setting of optimal monetary policies under a clean float, a managed exchange rate system (such as the EMS) and a monetary union, when welfare depends on unemployment and the cost of living. The results suggest...

A classical equilibrium model is analysed of two interdependent monetary economies in which it is assumed that cash is the only asset, and which is characterized by perfect foresight, flexible exchange rates and imperfect substitution between home and foreign goods. The first-best optimum sets...

It is shown that, when there is a genuine long-run trade-off between inflation and output, coordination under pre-commitment yields substantial improvements in economic welfare. The analysis is conducted within the context of a two-country model with capital accumulation, immobile labour,...

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...

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

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...

The optimal reaction to a pending productivity shock of which the expected arrival time increases with global warming is to accumulate more precautionary capital to smooth consumption and to levy a carbon tax, proportional to the marginal hazard of a catastrophe, to curb the risk of climate...
