The diversity of knowledge and skill is an important element of a national system of innovation. This study proposes a theory of how certain labor market institutions affect diversity, and through that route affect levels of innovation. Specifically, unemployment protection (UP) encourages diversity by reducing the risk burden of a broad range of learning, or human capital investment; for that reason, UP fosters innovation. Employment protection (EP) reduces the risk burden of a much narrower range of learning; for this reason, it will not enhance diversity to the extent UP does, and it may actually depress overall diversity and innovation. These approach differs from previous research on labor market insurance and skill formation, much of which has dealt with a distinction between general and specific skills, and which has treated the effects of UP and EP as similar. Estimating the effects of UP and EP on patenting for 25 OECD countries over 24 years, the authors found a positive effect from UP, a negative effect from EP, and evidence that the UP effect is mediated by diversity of skill
They were once the central element in state-funded research, but now the research bodies need to redefine their role as partners in the innovation process, responding more efficiently to the needs of society and businesses. In agriculture, the concept of...
This paper compares lessons learned from nine studies that explored institutional determinants of innovation towards sustainable intensification of West African agriculture. The studies investigated issues relating to crop, animal, and resources management in Benin, Ghana, and Mali.The studies showed that...
De nombreux agriculteurs africains pratiquent des formes d'agriculture potentiellement qualifiables de "?biologiques?". Pourtant, la capacité de l'agriculture biologique à répondre aux enjeux de la sécurité alimentaire en Afrique est encore mal connue, car il existe peu de références expérimentales disponibles...
Biotechnology offers great potential to contribute to sustainable agricultural growth, food security and poverty alleviation in developing countries. Yet there are economic and institutional constraints at national and international levels that inhibit the poor people's access to appropriate biotechnological innovations....
L'article propose d'utiliser le concept de sécurisation alimentaire pour étudier les actions et processus qui améliorent une situation alimentaire, plutôt que celui de sécurité alimentaire qui se réfère avant tout à la satisfaction de besoins alimentaires. Dans une première partie,...
