Germany remains Europe's largest and most diversified source of new technology, but still lags in the fastest growing areas of today's high technology. After World War II, West-German technology policy sought to rebuild the institutions which had supported Germany's leadership in the high-tech...

In this paper, we present a standard quality ladders endogenous growth model with one significant new assumption, that it takes time for firms to learn how to export. We show that this model without Melitz-type assumptions can account for all the evidence that the Melitz (2003) model was...

This econometric analysis investigates the impact of changes in sectoral valueadded prices and total factor productivity (TFP) on the equilibrium relative wage of low-skilled workers in eleven high-income countries. The key finding is that TFP growth mandated an increase in the unskilled wage,...

Does immigration accelerate sectoral change towards high-productivity sectors? This paper uses the mass displacement of ethnic Germans from Eastern Europe to West Germany after World War II as a natural experiment to study this question. A simple two-sector model of the economy, in which moving...

This paper develops two extensions of the dynamic model presented in Melitz (2003). The first extension consists in the introduction of technology choice between three alternative production technologies: L, M and H. L is assumed to be the same as Melitz’s single production technology, while M...

Empirical data show that firms tend to improve their ranking in the productivity distribution over time. A stickyprice model with firm-level productivity growth fits this data and predicts that the optimal long-run inflation rate is positive and between 1.5% and 2% per year. In contrast, the...

Based on Baumol’s cost-disease model, we develop two alternative measures of the change in the productivity of schooling. Both productivity measures are based on changes in the relative price of schooling. We find that in most OECD countries the price of schooling has increased faster in...

This paper builds upon Hoon and Phelps (1992, 1997) to ask how much of the evolution of the unemployment rate over several decades in country can be explained by real factors in an equilibrium model of the natural rate where country's productivity growth depends upon its distance from the...

We explore the uses of double-calibrated general equilibrium models as a decomposition tool for analysing contributory factors in the growth and increasing wage inequality in an advanced economy (the UK) since 1979. Calibration of a model to start and end years, based upon an assumed functional...
