A significant part of the patents held by a firm are not used. We show that, given the uncertainty of invention quality at the patent application stage and the sunk cost incurred for obtaining and developing a patent, the patent (internal) utilization rate declines with the (anticipated) size of...

Este artigo apresenta uma análise exploratória sobre os principais fatores que condicionam padrões de aprendizado, práticas cooperativas e desempenho inovativo em aglomerações produtivas no Brasil. Tal análise baseia-se em evidências empíricas oriundas de um conjunto de 28 estudos de...

This paper investigates the impact of alternative environmental policy instruments on technological innovations aiming to improve energy-efficiency in buildings. The empirical analysis focuses on three main types of policy instruments, namely regulatory energy standards in buildings codes,...

This paper studies the implications for climate policy of the interactions between environmental and knowledge externalities. Using a numerical analysis performed with the hybrid integrated assessment model WITCH, extended to include mutual spillovers between the energy and the non-energy...

In this paper we modify a standard quality ladder model by assuming that R&D is driven by outsider firms and the winners of the race sell licenses over their patents, instead of entering directly the inter- mediate good sector. As a reward they get the aggregate profit of the industry. Moreover,...

This paper sets out an analytical framework for doing research on the question of how to use agricultural research for innovation and impact. Its focus is the Research Into Use programme sponsored by the UK's Department for International Development (DFID). This is one example of a new type of...

Over the last 10 years much has been written about the role of the private sector as part of a more widely-conceived notion of agricultural sector capacity for innovation and development. This paper discusses the emergence of a new class of private enterprise in East Africa that would seem to...

Enhancing impacts of international development interventions has become a central issue of the twenty-first century. Conventional monitoring and evaluation (M&E) tools either focus on efficiency (output-to-input relationships) or strive to demonstrate a logical progression from specific actors...

Using new data on citations to university patents and scientific publications, and measures of distance based on Google maps, we study how geography affects university knowledge diffusion. We show that knowledge flows from patents are localized in two respects: they decline sharply with distance...

We construct an endogenous growth model that includes a cultural variable along the dimension of individualism-collectivism. The model predicts that more individualism leads to more innovation because of the social rewards associated with innovation in an individualist culture. This cultural...
