Our results on the relationship between R&D spillovers and cooperation in R&D suggest that it is necessary to distinguish different aspects of external information flows. We construct firm-specific measures of incoming spillovers and appropriability from survey data on Belgian manufacturing...

Successful innovation depends on the development and integration of new knowledge in the innovation process. In order to innovate successfully, the firm will combine different innovation activities. In addition to doing own research and development, firms typically are engaged in the acquisition...

We explore the relationship between innovation activity, productivity, and exports using a panel of Spanish manufacturing firms for 1990-1998. Our results - based on non-parametric tests - suggest that firm innovation status is important in explaining the positive export-productivity association...

The theoretical effects of labour regulations such as employment protection legislation (EPL) on innovation is ambiguous, and empirical evidence has thus far been inconclusive. EPL increases job security and the greater enforceability of job contracts may increase worker investment in innovative...

We analyze incentives to develop entrepreneurial ideas for venture capitalists (VCs) and incumbent firms. If VCs are sufficiently better at judging an idea's value and if it is sufficiently more costly to patent low than high value ideas, VCs acquire valuable ideas, develop them beyond the level...

How does firm entry affect innovation incentives and productivity growth in incumbent firms? Micro-data suggests that there is heterogeneity across industries - incumbents in technologically advanced industries react positively to entry, but not in laggard industries. To explain this pattern, we...

This Paper empirically tests the ‘bounds approach’ to industry structure proposed by Sutton ((1991), (1998)). To carry out this task, we focus on the chemical industry. Part of the novelty in this exercise is that we work on the finest possible level of disaggregation. Also, we identify...

This Paper examines the effect of price competition on innovation, market structure and profitability in R&D-intensive industries. The theoretical predictions are tested using UK data on the evolution of competition, concentration, innovation counts and profitability over 1952-77. The...

We develop a parsimonious model of innovating firms rich enough to confront firm-level evidence. It captures the dynamic behaviour of individual heterogeneous firms, describes the evolution of an industry with simultaneous entry and exit, and delivers a general equilibrium model of technological...

This paper modifies the heterogenous firms and trade model by Melitz (2003) by explicitly modelling the entry cost of a firm in a new market as a function of market size. This leads to several new predictions compared to the standard model: The productivity of non exporters and exporters depends...
