This paper builds a framework for the analysis of macroeconomic fluctuations that incorporates the endogenous determination of the number of producers and products over the business cycle. Economic expansions induce higher entry rates by prospective entrants subject to irreversible investment...

In this paper we describe some of the opportunities and perils for international monetary cooperation associated with EMU. Our approach brings together two strands in the literature; one concerned with institutions, the other focusing on policy consensus. Previous work on the subject has featured...

International financial integration has greatly increased the scope for changes in a country's net foreign asset position through the "valuation channel" of external adjustment, namely capital gains and losses on the country's external assets and liabilities. We examine this valuation channel...

Smaller firms sell more equity in response to expansions than do larger firms. Also, consumption is more pro-cyclical for high income groups than others. In this paper, we present a model that captures key features of both of these patterns found in recent empirical studies. Managers own firms...

Deviations from long-run price stability are optimal in the presence of endogenous entry and product variety in a sticky-price model in which price stability would be optimal otherwise Long-run inflation (deflation) is optimal when the benefit of variety to consumers falls short of (exceeds) the...

This paper introduces a new empirical model of international trade flows based on an import intensity-adjusted measure of aggregate demand. We compute the import intensity of demand components by using the OECD Input-Output tables. We argue that the composition of demand plays a key role in...

The global crisis that began in 2008 reheated the debate on market deregulation as a tool to spur 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 study optimal fiscal policy when product variety is endogenous and products are long-lived assets for firms. Depending on preferences, product creation should be either subsidized or taxed in the long run, by subsidizing or taxing dividends. In the most empirically relevant case, dividends...

EMU is a completely new policy regime which has significant economic implications and which, it is hoped, will ultimately enhance the role of Europe on the world stage. EMU and Economic Policy in Europe takes stock of the initial experiences of EMU and assesses the challenges which will have to...
