Capital accumulation and creative destruction is modeled together with risk-averse households. The novel aspect - risk-averse households - allows to use well-known models not only for analyzing long-run growth as in the literature but also short-run fluctuations. The model remains analytically...

Several empirical papers have shown that international trade has a positive causal effect on a country's GDP or growth rate. A common conclusion from these results is that a free trade policy will increase a country's GDP. This comment does not dispute the empirical findings per se but questions...

The literature on endogenous growth cycles predicts countercyclical R&D expenditure. Aggregate R&D expenditure in G7 countries from 1973 to 1997 seems to be procyclical. Implications for future theoretical research are discussed.

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

Globalisation (in the sense of increased international trade) is usually associated with gains from trade but also distributional effects where e.g. capital owners gain and workers lose, both in real terms. In recent years, globalisation seems to be synonymous to international mergers of firms....

Existing literature repeatedly documented a strong correlation between trade and growth. It has also shown a causal effect of imports (though not necessarily exports) on growth in simultaneous equation models but to a lesser extent in Granger-causality tests. Export and import taxes have...

Der Außenbeitrag einer Ökonomie wird nach dem intertemporalen Ansatz zum Verständnis der Leistungsbilanz verursacht durch inländische Spar- und Investitionsentscheidungen. Dieser Ansatz wird erweitert umeine theoretische und empirische Analyse der Auswirkungen laufender internationaler...

This paper provides the proofs to the analysis of a continuous time matching model with saving in Bayer and Wälde (2010a). The paper proves the results on consumption growth, provides an existence proof for optimal consumption and a detailed derivation of the Fokker-Planck equations.

Working time accounts allow rms to smooth their demand for hours employed. Descriptive literature suggests that this reduces turnover and inhibits increase in unemployment during recessions. We model theoretically the optimal choice of hours by a rm with a working time account. We show that...

By how much does an increase in operating effectiveness of a public employment agency (PEA) and a reduction of unemployment benefits reduce unemployment? Using a recent labour market reform in Germany as background, we find that an enhanced effectiveness of the PEA explains about 20% of the...
