Recent empirical evidence suggests that product creation is pro-cyclical and it occurs largely within existing firms. Motivated by these findings, the current paper investigates the role of intra-firm product scope choice in a general equilibrium economy with oligopolistic producers. We show...

We show that a one-sector real business cycle model with variable capital utilization and mild increasing returns-to-scale is able to generate qualitatively as well as quantitatively realistic aggregate fluctuations driven by news shocks to future consumption demand. In sharp contrast to many...

The standard one-sector real business cycle model is unable to generate expectations-driven fluctuations. The addition of countercyclical markups and modest investment adjustment costs offers an easy fix to this conundrum. The simulated model generates quantitatively realistic business cycles...

High degrees of relative risk aversion induces indeterminacy in cash-in-advance economies. In a small open economy context, this paper finds that endogenous money growth rules can pre-empt such sunspot equilibria in an open economy context. The most promising candidates are policies that...

This paper evaluates complementarities of labor market institutions and the business cycle in the context of a stochastic dynamic general equilibrium model economy. Matching between workers and vacancies with endogenous time spent in search, Nash-bargained wages, payroll taxation, and...

The article examines the proposition that preference shocks play a central role in our understanding of the Great Depression. I identify a series of unusually large negative shocks that destabilized the U.S. economy during the 1930s. When the artificial economy is paired with variable capital...

We show that an otherwise standard one-sector real business cycle model with variable capital utilization and mild increasing returns-to-scale is able to generate qualitatively as well as quantitatively realistic aggregate fluctuations driven by news shocks to two formulations of future...

and unemployment.

We examine the plausibility of expectations-driven cyclical fluctuations in an otherwise standard one-sector real business cycle model with variable capital utilization and mild increasing returns-to-scale in production. Due to a dominating wealth effect, our model is able to generate...

The paper finds empirical evidence on the ripple effect of sunspots on the interwar German economy. It identifies a sequence of negative shocks to expectations for the 1927 to 1932 period. The artificial economy predicts the 1928-1932 depression and a long boom from 1933 onwards. Overall, a...
