This paper proposes a model where firms invest in secrecy to limit technological spillovers accruing to their competitors, in addition to investing in cost-reducing R&D. The main result of the paper is that increases in spillovers increase secrecy, suggesting that legal and strategic protection...

Liberalisation has had a marked effect on innovative activities in the electricity industry. R&D and patenting activities are generally regarded respectively as innovative inputs to and outputs from technological progress. Electricity reforms have resulted in a reduction in R&D spending in the...

This paper proposes a framework to account for innovation similar to the usual accounting framework in production analysis and a measure of innovativity comparable to that of total factor productivity. This innovation accounting framework is illustrated using micro-aggregated firm data from the...

This paper studies the persistence of innovation and the dynamics of innovation output in Dutch manufacturing using firm data from three waves of the Community Innovation Surveys (CIS), pertaining to the periods 1994-1996, 1996-1998, and 1998-2000. We estimate by maximum likelihood a dynamic...

This paper compares pairwise the innovation performance of Canada with France and Germany, respectively. The comparison is based on two ordered probit models with sample selection, one where innovation is measured by the introduction of new-to-the firm products and one where it is measured by...

The precompetitive R&D literature has viewed cooperative and noncooperative R&D as substitutes. In this paper a more realistic approach is taken, where both cooperative and noncooperative R&D are performed in parallel. In the first stage firms determine the optimal investments in both types of...

A very striking change in product selection over the last century has been the increased degree of specialisation of durable goods. To analyse these changes this paper introduces a new form of product differentiation called functional. It is shown that when a homogeneous population demands...
