Twenty years ago, Harvard Business School economist and strategy professor Michael Porter stood conventional wisdom about the impact of environmental regulation on business on its head by declaring that well designed regulation could actually enhance competitiveness. The traditional view of...

This paper introduces dynamics in the R&D to innovation and innovation to productivity relationships, which have mostly been estimated on cross-sectional data. It considers four nonlinear dynamic simultaneous equations models that include individual effects and idiosyncratic errors correlated...

Using a unique panel data of Dutch innovation and financial variables we empirically investigate how financing and innovation vary across firm characteristics. The study also tries to gauge the extent of market failure due to the presence of financing frictions. Our main findings can be...

We review the econometric literature on measuring the returns to R&D. The theoretical frameworks that have been used are outlined, followed by an extensive discussion of measurement and econometric issues that arise when estimating the models. We then provide a series of tables summarizing the...

This paper studies vertical R&D spillovers between upstream and downstream firms. The model incorporates two vertically related industries, with horizontal spillovers within each industry and vertical spillovers between the two industries. Four types of R&D cooperation are studied: no...

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...

This document seeks to lay the groundwork for a government policy on free and open source software. We briefly characterize the extent of the open source software phenomenon. We analyse its pros and cons for the government, in its role as both an engine of economic development and a large user...

Ce texte vise à circonscrire les fondements d'une politique gouvernementale à l'égard du logiciel libre et ouvert (open source software). Nous caractérisons brièvement l'ampleur du phénomène du logiciel libre et nous en analysons les avantages et inconvénients pour le gouvernement tant...

This paper explores the aggregation problem and illustrates its relevance using data for the Netherlands from the third Community Innovation Survey (CIS3), and production and financial statistics. It compares the results of an innovation output equation that was estimated using data on...
