Climate change is one of the greatest challenges of this century. Mitigation requires a large-scale transition to a low-carbon economy. This paper provides an overview of the rapidly growing literature on the role of macroeconomic and financial policy tools in enabling this transition. The...

We develop a model to analyze the macroeconomic effects of a scaling-up of aid and assess the implications of different policy responses. The model features key structural characteristics of low-income countries, including varying degrees of public investment efficiency and a learning-by-doing...

This paper surveys three types of monetary arrangements. It considers how the choice of an exchange rate regime, the degree of central bank independence, or choice of currency unions or boards depends not only on economic considerations but also on political economy considerations. In economic...

The choice of assigning monetary or fiscal policy to external balance is complicated when the authorities are concerned with both the current account balance and the exchange rate. A strategy of using monetary policy to control the current account via the exchange rate may fail, because the...

We introduce subsistence requirements in food consumption into a simple new-Keynesian model with flexible food and sticky non-food prices. We study how the endogenous structural transformation that results from subsistence affects the dynamics of the economy, the design of monetary policy, and...

In closed or open economy models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. We analyze this result in the context of developing economies, where a large proportion of households are credit constrained...

The ""conservative central banker"" has come under attack recently. On the basis of models in which there is explicit interaction between trade union behavior and monetary policy, it has been argued that if ''trade unions'' are averse to inflation, welfare will be lower with a conservative than...

This paper examines the issue of whether countries can improve their welfare by coordinating macroeconomic policies. The main purpose is to compute the gains from international monetary cooperation as the difference between the steady state consumption levels associated with the Nash and the...
