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...

Unification fundamentally changed the terms of quantitative macroeconomic analysis for Germany. Two main areas concerned are data availability for the eastern part of Germany and structural changes within the behavioural equations after unification.

In this paper, a theoretical model of the impact of product and process innovations on output, capacity utilization, employment, and prices is developed. The model is estimated with micro-data for West German manufacturing firms from the ifo firm panel. The empirical results reveal that...

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, 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...

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...
