We use a life cycle model of consumption and portfolio choice to study the effects of social security on the investment decisions of households for the European case. Our model is mainly based on the one developed by Cocco, Gomes, and Maenhout (2005). We extend it by unemployment risk using Markov chains to model the transition between different employment states. In contrast to most models in the ...
The purpose of this contribution is to illustrate the mechanism by which higher oil prices might lead to lower interest rates in the context of a simple model that takes into account the global external savings equilibrium. The simple model has interesting implications for how one views the huge US current account deficit and how the emergence of China's savings surplus and oil supply shocks impact ...
Die konjunkturelle Lage in Deutschland hellt sich zwar auf, der Aufschwung gewinnt aber nicht hinreichend an Breite. Die mangelnde Konsumbereitschaft der privaten Haushalte trübt noch die Stimmung. Trotz leichter Zuwächse kann von einer für einen Aufschwung typischen Erholung der Binnennachfrage bislang nicht die Rede sein. Die Hauptursache für die Konsumzurückhaltung in den vergangenen Jahren ist ...
After the collapse in the early transition years, saving rates in Eastern European EU-accession countries have recovered strongly. But is private saving in these countries now driven by the same forces as in the EU? A GMM estimator is applied to analyze the determinants of private saving in both country groups. The main results are: saving rates are rather persistent; income growth increases saving, ...
This note explores the relationship between the price elasticity of demand and the R&D intensity of the product. We introduce the concept of R&D intensity into a standard Dixit-Stiglitz/Krugman-type setting. R&D activity is treated as a fixed cost of production. Within this framework, sectors with a higher R&D intensity show a lower price elasticity of demand. This proposition is confirmed by an empirical ...
In diesem Papier wird an Hand eines Vektorfehlerkorrekturmodells (VECM) für den französischen Arbeitsmarkt untersucht, wie sich die dort Anfang 2000 eingeführte Verkürzung der Regelarbeitszeit in Verbindung mit Subventionen der Sozialversicherungsbeiträge ausgewirkt hat. Theoretisch sind die Effekte der Arbeitszeitverkürzung auf die Beschäftigung nicht eindeutig. Deshalb führen wir mit einem Arbeitsmarktmodell ...
