This paper is concerned with the role of firm heterogeneity under credit constraints for economic growth. We focus on firm size, innovativeness and credit constraints in a semi-endogenous growth model reflecting recent empirical findings on firm heterogeneity. It allows for an explicit solution...

We identify measures of shocks to total factor productivity and preferences from two real business cycle models and subject them to Granger causality tests to see whether they can be considered exogenous to other plausible sources of the German business cycle. For the period 60.i to 89.iv no...

This note extends the finding of Benhabib and Rusticchini (1994) who provide a class of SDGE models, whose solution is characterized by a constant savings rate. We show that this class of models may be interpreted as a standard representative agent SDGE model with costly adjustment of capital...

Summary What does account for the persistence of monetary shocks in dynamic general equilibrium models of the business cycle? A number of papers have dealt with that question and point at labor market frictions besides those introduced by overlapping wage contracts. In this paper I investigate...

Ineffektivität der Wirtschaftspolitik bei "rationalen Erwartungen"? Ein Kommentar mit anderen Argumenten für Bernd-Thomas Rambs These In einem vor kurzem in dieser Zeitschrift veröffentlichten Artikel weist Bernd-Thomas Ramb die These als modellspezifisch zurück, bei rationalen Erwartungen...

Klein (2000) advocates the use of the Schur decomposition of a matrix pencil to solve linear rational expectations (RE) models. Meanwhile his algorithm has become a center piece in several computer codes that provide approximate solutions to (non-linear) dynamic stochastic general equilibrium...

Many algorithms that provide approximate solutions for dynamic stochastic general equilibrium (DSGE) models employ the generalized Schur factorization since it allows for a flexible formulation of the model and exempts the researcher from identifying equations that give raise to infinite...
