Current explanations of why a growing economy necessarily goes through booms and recessions predict a countercyclical R&D investment. As this is very controversial from an empirical perspective, a stochastic Poisson model of endogenous business cycles and growth is presented where the...

It is common practice to estimate the volatility-growth link by specifying a standard growth equation such that the variance of the error term appears as an explanatory variable in this growth equation. The variance in turn is modelled by a second equation. Hardly any of existing applications of...

It is common practice to estimate the volatility-growth link by specifying a growth equation such that the variance of the error term appears as an explanatory variable. Hardly any of existing applications of this framework includes exogenous controls in the variance equation. We show that the...

A model of growth with endogenous innovation and distortionary taxes is presented. Since innovation is the only source of volatility, any variable that influences innovation directly affects volatility and growth. This joint endogeneity is illustrated by working out the effects through which...

This paper proposes a simple general equilibrium model with labour market frictions and an imperfect financial market. The aim of the paper is to analyse the transitional dynamics of unemployment and vacancies when financial constraints are in place. We model the financial sector as a...

Aus historischer Sicht spielten Arbeiterbewegungen eine entscheidende Rolle in der Entwicklung sicherer Arbeitsplätze. Unfallschutz am Arbeitsplatz ist für Unternehmen kostspielig, führt aber aufgrund eines Rückgangs der Krankheitstage zu einem Anstieg des Arbeitsangebots. In einer freien...
