A primer on R&D cooperation among firms

This paper provides an introduction to the economic analysis of R&D cooperation among firms. Basing on some stylized facts, we survey the relevant theoretical literature in order to discuss the benefits and the costs that firms face when they cooperate in R&D. We then analyze the pros and the cons of R&D cooperation from a policy-making perspective. We find that R&D cooperation is usually considered welfare improving and can be promoted by several policies. Finally, we discuss paths of research not yet taken in the theoretical literature.
