The Schumpeterian theory of long waves has given rise to an intense debate on the existenceof clusters of basic innovations. Silverberg and Lehnert have criticized the empirical part ofthis literature on several methodological accounts. In this paper, we propose the methodologyof Poisson...

Industrialization, and the association between technological advance and economic growth, brought Europe world economic leadership in the 19th century. However, in the course of the 20th century, European leadership was lost to the United States, as well as a number of dynamic Asian economies,...

This paper investigates whether the distinction between patent citations added by the inventor or the examiner is relevant for the issue of geographical concentration of knowledge flows (as embodied in citations). The distinction between inventor and examiner citations enables us to work with a...

Technological change is argued to be taking place along ordered and selective pat-terns, shaped jointly by technological and scientific principles, and economic and other societal factors. Historical, descriptive analysis is often used to analyze these ''trajectories''. Recently, quantitative...

This paper explores the self-organising principles of horizontally-integrated innovation networks. It isshown that such networks can self-organising in environments where the co-ordination and production ofnew knowledge is itself a complex, dynamic and highly non-linear processes. The paper...

Politicians understand that a conventional double dividend policy - defined asreduction of greenhouse gas emissions and unemployment through taxation of energy and CO2emissions and subsidization of wage costs - and the aim of keeping international competitivenessof all sectors intact may be...

We extend an earlier model of innovation dynamics based on invasive percolation by adding endogenous R&D search by economically motivated firms. The {0,1} seeding of the technol-ogy lattice is now replaced by draws from a lognormal distribution for technology ‘difficulty’. Firms are rewarded...

This paper examines the importance of knowledge-skill complementarity in the process of contemporary economic growth. By analyzing Dutch manufacturing and carrying out an extensive spillover and wage inequality analysis, it is shown that knowledge-intensive sectors pay their high-skilled workers...

This paper uses a novel database composed of 4,262 European chemical patents applied for by 693 firms during 1987-1996 to compare the relative effect of firm and regional characteristics on the production of technological hits (highly cited patents). By using an extensive set of controls, the...

In this paper we analyse the cognitive roots of the division of labour and relate it to the reduction of tacitness in the organisation and technology of a firm. We study the interaction between efforts of knowledge codification and problems of control in production from an evolutionary and...
