The Friedman rule states that steady-state welfare is maximized when there is deflation at the real rate of interest. Recent work by Khan et al. (2003) uses a richer model but still finds deflation optimal. In an otherwise standard new Keynesian model we show that, if households have hyperbolic...

*The European Union will enter Stage Three of Economic and Monetary Union (EMU) in 1999. The development of euro financial markets and thickness externalities in the use of the euro as means of payment will be the major factors determining the importance of the euro as an international currency....

The use of different currencies in the invoicing of international trade transactions plays a major role in the international transmission of economic fluctuations. Existing studies argue that an exporter’s invoicing choice reflects structural aspects of her industry, such as market share and...

This paper starts from the observation that parameter instability and model uncertainty are relevant problems for the analysis of monetary policy in small macroeconomic models. We propose to deal with these two problems by implementing a novel ‘thick recursive modelling’ approach. At each...

How should monetary policy respond to changes in financial conditions? In this paper we consider a simple model where firms are subject to idyosincratic shocks which may force them to default on their debt. Firms' assets and liabilities are denominated in nominal terms and predetermined when...

Under rational expectations monetary policy is generally highly effective in stabilizing the economy. Aggregate demand management operates through the expectations hypothesis of the term structure --- anticipated movements in future short-term interest rates control current demand. This paper...

The wave of crises that began in 2008 reheated the debate on market deregulation as a tool to improve economic performance. This paper addresses the consequences of increased flexibility in goods and labor markets for the conduct of monetary policy in a monetary union. We model a two-country...

We characterize the optimal sequential choice of monetary policy in economies with either nominal or indexed debt. In a model where nominal debt is the only source of time inconsistency, the Markov-perfect equilibrium policy implies the progressive depletion of the outstanding stock of debt,...

We analyze the policy trade-offs generated by local currency price stability of imports in economies where upstream producers strategically interact with downstream firms selling the final goods to consumers. We study the effects of staggered price setting at the downstream level on the optimal...
