Union density and determinants of union membership in 18 EU countries: evidence from micro data, 2002/031

Using representative individual-level data from the first round of the European Social Survey fielded in 2002/03, this article provides an empirical analysis of unionisation in 18 countries of the EU. We show that union density varies considerably in Europe, ranging from 84 per cent in Denmark to 11 per cent in Portugal. Estimating identical models for each country, we find that individuals’ probability of union membership is significantly affected by their personal characteristics, their attitudes and the characteristics of their workplace, whereas social factors seem to play a minor role. The presence of a union at the workplace and employees’ attitudes concerning strong unions are the two variables most strongly associated with unionisation.     

Dynamic asset allocation with stochastic income and interest rates

We solve for optimal portfolios when interest rates and labor income are stochastic with the expected income growth being affine in the short-term interest rate in order to encompass business cycle variations in wages. Our calibration based on the Panel Study of Income Dynamics (PSID) data supports this relation with substantial variation across individuals in the slope of this affine function. The slope is crucial for the valuation and riskiness of human capital and for the optimal stock/bond/cash allocation both in an unconstrained complete market and in an incomplete market with liquidity and short-sales constraints.     

Inside the black box: How important is the credit channel relative to the interest and exchange rate channels?

This paper develops a dynamic general equilibrium model to assess the importance of the credit channel relative to the interest and exchange rate channels. It is motivated by increasing theoretical and empirical evidence that credit market conditions affect the propagation of cyclical fluctuations in the economy. The relative contribution of each channel is determined by comparing the impulse responses when the relevant channel is suppressed with the impulse responses when all three channels are operating. The analysis shows that all three channels affect business cycle dynamics. But the interest rate channel has the largest effects in the transmission of shocks to the economy. The results suggest that it is substantially more important than the credit channel.     

On the equivalence between the overlapping-generations model and cyclical general-equilibrium models

We show that equilibrium cycles in an overlapping-generations model are equivalent to asymmetric equilibria in a general-equilibrium model. We use this equivalence to find equilibrium cycles in the overlapping-generations model with two and three generations, respectively. For the example with two generations we show that for certain parameter values cycles of all periods occur.     

Economic thought and the reform of the welfare state

Economics has become increasingly important in the analysis of the objectives, scope and effects of the welfare state and its future development, with the interesting result of producing growing support for 'liberalist' methods of social reform.     

Higher wages in exporting firms: self-selection, export effect, or both? First evidence from linked employer-employee data

While it is a stylized fact that exporting firms pay higher wages than non-exporting firms, the direction of the link between exporting and wages is less clear. Using a rich set of German linked employer-employee panel data we follow over time plants that start to export. We show that the exporter wage premium does already exist in the years before firms start to export, and that it does not increase in the following years. Higher wages in exporting firms are thus due to self-selection of more productive, better paying firms into export markets; they are not caused by export activities.     

Duration dependent unemployment benefits in trade union theory

The basic trade union model is generalized to allow for an unemployment benefit system consisting of two benefit levels, one for short-term and one for long-term unemployed, and a rule determining whether an unemployed is short- or long-term. Under relatively mild conditions we show that benefit systems with no or positive duration dependence are dominated by a system with negative duration dependence in the sense that all union members achieve higher utility, unemployment is lower, and benefit expenditures are smaller.
