This paper is devoted t.o an interpretation of both vacancy data and the Beveridgecurve. Officially reported vacancy data are critically reviewed. The theoretical foundation and empirical application of the Beveridge-curve is examined. We find that the Beveridge-curve is everything but a...

This paper constitutes an interim report on the development of a macroeconometric disequilibrium model. Despite several caveats the model as it stands can be used already for two purposes. First, it is possible to investigate the models forecasting abilities. While the estimation period of the...

In the paper, productivity convergence is analyzed with a broad panel of industry sector data for the United States and Germany for 1960-1990. The time-series/cross-sectoral data set allows to investigate country-specific convergence, and to control for sector-specific differences in human...

In the paper, the productivity growth of German sectors is analyzed. Sectoral production functions are estimated with annual national account data of 51 sectors from 1960-1990. Both, the pure Solow growth model and the Solow model augmented with human capital do not account for observed...

The paper deals with causes and consequences of constraints on the adjustment of employment. First, a model of a delayed adjustment of employment and capital is worked out. This model is augmented with linear constraints on the adjustment speed of labour supply and demand. The aggregate model is...

In the paper, the sources of productivity growth are investigated by an empirical analysis with micro data for West-German manufacturing firms. The theoretical framework corresponds to an augmented growth accounting approach based on a production function. The empirical results reveal that...

In the paper, a model of the firm with a delayed adjustment of prices and supply is analyzed. Prices and supply are determined under uncertainty about the location of the demand curve. Three models are distinguished: a price setting with predetermined supply, supply determination with...

In this paper a variety of theories concerning the wage and price formation in Germany are tested. More specifically, wage and price equations are specified in a fairly general manner which nests several theoretical arguments (such as the target real wage bargaining model, hysteresis effects,...

A dynamic model of the firm is worked out, which pays special attention to a delayed adjustment of employment, investment, and the production technology. A three-step decision structure is assumed, with short-run adjustment of output, medium-run adjustment of employment, and long-run adjustment...

In the paper, some empirical results from a macroeconometric disequilibrium model for the Federal Republic of Germany are reported. In the theoretical model, a delayed adjustment of employment and investment is analyzed. Market disequilibrium is introduced by allowing for a sluggish adjustment...
