Shocks to bank lending, risk-taking and securitization activities that are orthogonal to real economy and monetary policy innovations account for more than 30 percent of U.S. output variation. The dynamic effects, however, depend on the type of shock. Expansionary securitization shocks lead to a...

We study the effects of changes in uncertainty about future fiscal policy on aggregate economic activity. Fiscal deficits and public debt have risen sharply in the wake of the financial crisis. While these developments make fiscal consolidation inevitable, there is considerable uncertainty about...

Price volatility, reflecting the ability to absorb exogenous supply- or demand shocks, is an important dimension of market performance. In this paper we present a model to study the factors determining the price volatility of markets of basic foodstuffs in pre industrial societies. This model is...

Not in an estimated DSGE model of the US economy, once we account for the fact that most of the high-frequency volatility in wages appears to be due to noise, rather than to variation in workers' preferences or market power.

This paper examines how supply-side policies may play a role in fighting a low aggregate demand that traps an economy at the zero lower bound (ZLB) of nominal interest rates. Future increases in productivity or reductions in mark-ups triggered by supply-side policies generate a wealth effect...

How and why do financial conditions matter for real outcomes? The ‘workhorse model of money and liquidity’ of Kiyotaki and Moore (2008) shows how--with full employment maintained by flexible prices--shifting credit constraints can affect investment and future aggregate supply. We show that,...

I show how to construct a stochastic long-lived overlapping generation’s model that is based on a non-stochastic model developed by Olivier Blanchard and Philippe Weil and that nests the RBC model as a special case. My innovation over previous work is to add an aggregate stochastic shock. I...

This paper investigates the basic stylized facts of business cycles in the G7 countries using quarterly data from 1960-89. The methodology used is based on Kydland and Prescott (1990). The evidence suggests that the real business cycles model can account for several important stylized facts for...

The observation that liquidations are concentrated in recessions has long been the subject of controversy. One view holds that liquidations are beneficial in that they result in increased restructuring. Another view holds that liquidations are privately inefficient and essentially wasteful. This...

New Keynesian literature assumes symmetric industrial structure when analysing explanations of monetary non-neutrality. We analyse the impact of modifying this assumption by allowing for a mixed industrial structure; some industries are characterized by monopolistic competition, and others by...
