This paper attempts to quantify the aggregate net effect of government funding on business R&D in 17 OECD Member countries over the past two decades. Grants, procurement, tax incentives and direct performance of research (in public laboratories or universities) are the major policy tools in the...

This paper describes a new patent-based indicator of inventive activity. The indicator is based on counting all the priority patent applications filed by a country’s inventors, regardless of the patent office in which the application is filed, and can therefore be considered as a complete...

Cette étude analyse les effets de long terme de différents types de R-D sur la croissance de la productivité totale des facteurs, qui sont les effets « spillover » de la R-D. Les estimations économétriques sont conduites sur un panel de 16 pays de l’OCDE sur la période 1980-98. Les...

This study investigates the long-term effects of various types of R&D on multi-factor productivity growth, which are the spillover effects of R&D activities. Econometric estimates are conducted on a panel of 16 OECD countries, over the period 1980-98. All results are averages over countries and...

This study investigates the long-term effects of various types of R&D on multifactor productivity growth, which is the spillover effect of R&D. Econometric estimates are conducted on a panel of 16 OECD countries, over the period 1980-98. All results are averages over countries and time, and...

This paper explores the determinants of the probability for a patent application to result in a grant (as opposed to being rejected by the patent office or withdrawn by the patentee). A grant is interpreted as signaling the value of the invention. Guellec and van Pottelsberghe (2000) studied the...

This paper presents estimates of the long-term impact of various sources of knowledge (R&D performed by the business sector, the public sector and foreign firms) on multifactor productivity growth of 16 countries from 1980 to 1998. The main results show that the three sources of knowledge are...

The joint increase in the number and size of patents filed around the world puts patent systems under pressure. This paper addresses issues in measuring the voluminosity of patent applications and highlights patterns in its evolution. The results - based on a 2 million EPO applications database...

The joint increase in the number and size of patents filed around the world puts the patent system under pressure. This paper analyses the sources of this surge in number of claims and pages of patent applications at the EPO. Four hypotheses are scrutinized: the diffusion of national drafting...
