We explore the dynamic effects of news about a future technology improvement which turns out ex post to be overoptimistic. We find that it is difficult to generate a boom-bust cycle (a period in which stock prices, consumption, investment and employment all rise and then crash) in response to...

We develop a search-matching model, where firms search for customers (e.g. in form of advertising). Firms use long-term contracts and bargain over prices, resulting in a price mark up above marginal cost, which is pro- cyclical and depends on firms’ relative bargaining power. Product market...

We consider a real business cycle model with a productive externality and an aggregate non- convex technology set µa la Benhabib and Farmer embodying capacity utilization, which exhibits indeterminacy of the steady state and multiplicity of deterministic equilibria under plausible values of the...

An identical two-sector productivity shock causes Rybczynski (1955) and Stolper and Samuelson (1941) effects that release leisure time and initially raise the relative price of human capital investment so as to favor it over goods production. Modified by having the household sector produce human...

This paper contributes to the literature by documenting labor income share fluctuations in emerging economies and proposing an explanation for them. We show that emerging markets differ from developed markets in terms of changes in the labor share over the business cycle. Labor share is more...

Bereits Ende der siebziger Jahre wurde die Trennung zwischen lang- und kurzfristiger ökonomischer Analyse in Frage gestellt und von der Real Business Cycle (RBC)-Theorie kurze Zeit später analytisch überwunden. Der empirische Gehalt ursprünglicher RBC-Modelle erweist sich zwar insbesondere...

This paper introduces a nonlinear certainty-equivalent approximation method for dynamic stochastic problems. We first introduce a novel, stable, and efficient method for computing the decision rules in deterministic dynamic economic problems. We use the results as nonlinear and global...

In this paper, I investigate quantitatively how sensitive a typical backward-looking model used in monetary plicy analysis is to the Lucas critique. To do this, I use an equilibrium business cycle model with a Taylor-type rule for nominal money growth. The backward-looking model displays...

Recent work on the effects of permanent technology shocks argue that the basic RBC model cannot account for a negative correlation between hours worked and labor productivity. In this paper, I show that this conjecture is not necessarily correct. In the basic RBC model, I find that hours worked...

In this paper, I try to shed some new light on the puzzle why the Lucas critique, belived to be important by most economists, seems to have received very little empirical support. I use a real business cycle model to examine the properties of the super exogeneity test, which is used to detect...
