This paper surveys empirical studies employing trade mark data that exist in the economic literature to date.  Section 1) documents the use of trade marks by firms in several advanced countries including Australia, the United Kingdom and the United States, 2) reviews different attempts to gauge...

A common assumption in innovation policy circles is that creative and inventive firms will help to sustain employment and wages in high wage countries. The view is that firms in high cost production locations that do not innovate are faced with loss of market share from import competition, so...

This paper documents the increase in R&D intensity in the UK manufacturing sector in the period following the introduction of R&D tax credits in 2000-02. This increase is broadly in line with that predicted by econometric studies of the impact of R&D tax credits, notably Bloom, Griffith and Van...

This Paper examines which firms from a heterogeneous pool are more likely to join together and form a research joint venture (RJV). It differs from previous contributions as it introduces a set of realistic hypothesis on the characteristics of research co-operation and information sharing....

Complex high technology industries are increasingly affected by patent thickets in which firms' patents mutually block the use of important technologies. Firms facing patent thickets patent intensively to acquire bargaining chips and use licensing to ensure freedom to operate. Such licensing...

We investigate incidence and evolution of patent thickets. Our empirical analysis is based on a theoretical model of patenting in complex and discrete technologies. The model captures how competition for patent portfolios and complementarity of patents affect patenting incentives. We show that...
