I characterize cyclical fluctuations in the cross-sectional dispersion of firm-level productivity in the U.S. manufacturing sector. Using the estimated dispersion, or "risk," stochastic process as an input to a baseline DSGE financial accelerator model, I assess how well the model reproduces...

Traditional approaches to separate the underlying trend of potential output from cyclical developments mostly rely on the concept of nonaccelerating inflation output and are thus unable to detect upswings caused by the financial cycle, which often appear to be unsustainable in the long run. In...

This paper develops a macroeconomic model of the interaction between consumer debt and firm debt over the business cycle. I incorporate interest rate spreads generated by firm and household loan default risk into a real business cycle model. I estimate the model on US aggregate data. This allows...

This paper studies the role of collateral constraints in transforming small monetary shocks into large persistent output fluctuations. We do this by introducing money in the heterogeneous-agent real economy of Kiyotaki and Moore (1997). Money enters in a cash-in-advance constraint and is...

This paper examines the effectiveness of monetary aggregates through various nominal interest rates by integrating the financial sector into the Cash-in-Advance (CIA) economy. The model assumes that there are two types of representative agents in the financial sector, which are: productive banks...

We propose an event-study research design to identify the nature and propagation of large unusual shocks in DSGE models and apply it to study the macroeconomic effects of the Covid shock. The initial outbreak is represented as the onset of a new shock process where the shock loads on wedges...

The Real Business Cycle (RBC) research program has grown specularly over the last decade, as its concepts and methods have diffused into mainstream macroeconomics. Yet, there is increasing skepticism that technology shocks are a major source of business fluctuations. This chapter exposits the...

This paper introduces lumpy micro-level investment into a sticky information general equilibrium model. Lumpy investment arises because of inattentiveness in capital investment decisions instead of the more popular assumption of non-convex adjustment costs. Sticky information is the only source...
