Recent empirical studies suggest a need for a flexible patent regime responding to industry characteristics. In practice, sector-specific modifications of patent strength already exist but lack theoretical foundation. This paper intends to make up for this neglect by scrutinizing in what...

This paper uses a long time series of German employment data to test the theory of Ngai & Pissarides (2007). The theory suggests that the shift of employment shares from manufacturing to services is due to divergent growth rates of total factor productivity (TFP) in the two sectors. To test the...

The Producer Price Index (PPI) for the United States suggests that semiconductor prices have barely been falling in recent years, a dramatic contrast to the rapid declines reported from the mid-1980s to the early 2000s. This slowdown in the rate of decline is puzzling in light of evidence that...

We develop a tractable dynamic general equilibrium model of oligopolistic competition with a continuum of heterogeneous industries. Industries are exposed to aggregate and industry-specific productivity shocks. Firms in each industry set value-maximizing state-contingent markups, taking as given...

Neoclassical economists argue that competition promotes efficiency. They consider technology as given though. In the long run, technological progress is an important determinant of the level of welfare and Schumpeter argued that monopoly rents help entrepreneurs to capture the gains of R&D and,...

This paper builds a New Keynesian industry dynamics model for the analysis of macroeconomic fluctuations and monetary policy. A continuum of heterogeneous firms populates the economy, markets are imperfectly competitive and nominal wages are sticky. An expansionary monetary policy shock triggers...

We model distribution, the delivery of goods to customers, as an activity governed by its own technology and undertaken by firms subsequently to production operations. We then use the model to investigate how distribution shapes innovation-driven economic growth. We contrast two canonical...

This paper addresses the empirical relationship between the level of competition and the rate of productivity growth across thirty sectors of the French production system during the period 1978- 2015. It shows that there exists an optimal level of competition for each sector that is defined by...

Much scope remains to make regulation of product markets more conducive to competition ? notwithstanding progress in recent years ? with substantial benefits for consumer welfare, productivity and employment. While the general competition legislation and enforcement framework is mostly...
