May 2015Above a Swamp: A Theory of High-Quality Scientific Production
with Bralind Kiri, Nicola Lacetera: w21143
Building on previous research to reinforce findings or point out limitations is essential for a healthy working of the scientific community because it allows science to self-correct and evolve, thus providing a more solid knowledge base to individuals, firms and societies. In this paper we propose a model to investigate the incentives of scientists to perform these activities of control and criticism when these activities, just like the production of high-quality research in the first place, are costly, and we study the strategic interaction among these incentives. We show that a certain fraction of low-quality scientific knowledge characterizes all the equilibria in the basic version of model. In fact, the absence of (detected) low-quality research in a field can be interpreted as the lac...
May 2011Individual Preferences, Organization, and Competition in a Model of R&D Incentive Provision
with Nicola Lacetera: w17031
Understanding the organization of R&D activities requires the simultaneous consideration of scientific workers' talent and tastes, companies' organizational choices, and the characteristics of the relevant industry. We develop a model of the provision of incentives to corporate scientists, in an environment where (1) scientists engage in multiple activities when performing research; (2) knowledge is not perfectly appropriable; (3) scientists are responsive to both monetary and non-monetary incentives; and (4) firms compete on the product market. We show that both the degree of knowledge spillovers and of market competition affect the incentives given to scientists, and these effects interact. First, high knowledge spillovers lead firms to soften incentives when product market competition i...
