This paper studies the role of endogenous producer entry and product creation for monetary policy analysis and business cycle dynamics in a general equilibrium model with imperfect price adjustment. Optimal monetary policy stabilizes product prices, but lets the consumer price index vary to...

This paper explores role of product adding and dropping within manufacturing firms over the business cycle. While a substantial body of work has explored the importance of the extensive margins of firm entry and exit in employment and output flows, only recently has research begun to examine the...

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

We study the stochastic behavior of a dynamic general equilibrium model with monopolistic competition. Each seller sells his product in the consumption goods as well as the investment goods market and has market power in both. Consumers derive utility from a CES aggregate of all the consumption...

Motivated by the long-standing debate on the pros and cons of competitive devaluation, we propose a new perspective on how monetary and exchange rate policies can contribute to a country's international competitiveness. We refocus the analysis on the implications of monetary stabilization for a...

We show that deviations from long-run stability of product prices are optimal in the presence of endogenous producer entry and product variety in a sticky-price model with monopolistic competition in which price stability would be optimal in the absence of entry. Specifically, a long-run...

Based on a sample of 56 countries, we find that while fiscal policy in the G-7 countries appears to be broadly consistent with Barro's tax smoothing proposition, in developing countries government spending and taxes are highly procyclical (i.e., government spending rises and taxes fall during...

This paper examines business cycles theoretically and empirically, with a quantitative study based on experience over the long run and in a cross section of countries. Several major questions in business cycle theory are explored. Theoretical concerns indicate that the properties of business...

We examine the start date of the Great Recession across OECD countries based on two successive quarters of negative GDP growth recession. For most OECD countries this establishes the start of recession in Q22008 or Q32008. We find that the Sahm Rule identifies the start of recession in the US to...

This paper compares fiscal cyclicality across advanced and developing countries, geographic regions as well as income levels over 1960-2016 period, then identifies factors that explain countries' government spending and tax-policy cyclicality. Public debt/tax base ratio provides a more robust...
