Starting in 1985, (West) German unions began to reduce standard hours on an industry-by-industry basis in an attempt to lower unemployment. Whether ‘work-sharing’ works – whether employment rises when hours per worker are reduced – is theoretically ambiguous. I test this using both...

The rapid wage increases observed in Eastern Germany over the past two years have important implications for the direction taken by structural change in this region. These implications are not solely negative, and remain controversial in the public debate. This paper discusses four aspects of a...

We examine how technological change affects wage inequality and unemployment in a calibrated model of matching frictions in the labour market. We distinguish between two polar cases studied in the literature: a ‘creative destruction’ economy where new machines enter chiefly through new...

This paper introduces a labour force participation choice into a standard labour market matching model embedded in a dynamic stochastic general equilibrium set-up. The participation choice is modelled as a trade-off between forgoing the expected benefits of being search active and engaging in...

This Paper considers a matching model of heterogeneous workers and jobs, which includes on-the-job search. High-educated workers transitorily accept unskilled jobs and continue to search for skilled jobs. We study the implications of this model for the unemployment rates of high and low-educated...

We study a labour market in which firms can observe workers’ output but not their effort, and in which a worker’s productivity in a given firm depends on a worker-firm specific component, unobservable for the firm. Firms offer wage contracts that optimally trade off effort and wage costs. As...

Germany is generally regarded as the nominal anchor for Europe. Its participation is the sine qua non of EMU. It has been the largest net contributor to EU finances, the leading proponent of greater economic and political union, and the leading example of the virtues of fiscal and monetary...

A labour-matching economy with ex post heterogeneous firms is presented. When bargaining over the wage, firms and workers do not know the level of product demand. Once demand is realized, hours of work are chosen. We show that the existence of a legal workweek may enhance efficiency with respect...

A new methodology is described which tests between various equilibrium theories of unemployment using matching data. The Paper shows how to correct econometrically for temporal aggregation effects, where the econometrician’s aim is to identify a matching process using data which is recorded...

Many workers believe that personal contacts are crucial for obtaining jobs in high-wage sectors. On the other hand, firms in high-wage sectors report using employee referrals because they help provide screening and monitoring of new employees. This Paper develops a matching model that can...
