Countercyclical markups are a key transmission mechanism in many endogenous business cycle models. Yet, recent findings suggest that aggregate markups in the US are procyclical. The current model addresses this issue. It extends Gall's (1994) composition of aggregate demand model by endogenous...

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...

This paper analyzes the role of variable work effort in inducing sunspot equilibria in real business cycle models. Not only is it demonstrated that variable workers' work intensity reduces the degree of increasing returns that is needed to generate indeterminacy but it is also shown that this...

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...

This paper presents a small open economy version of the Benhabib and Farmer [2] two sector optimal growth model with production externalities. It is shown that indeterminacy is considerably easier to obtain under a regime of perfect world capital markets than in the closed economy variant....

We compare and contrast alternative explanations of the Roaring Twenties. Starting with the RBC model as a benchmark, we also examine a model with indeterminacy and self-fulfilling expectations (SFE), and one with credit shocks. Historical and anecdotal evidence provides support for each of...
