We consider a moral hazard problem with multiple principals in a continuous-time model. The agent can only work exclusively for one principal at a given time, so faces an optimal switching problem. Using a randomized formulation, we manage to represent the agent's value function and his optimal effort by an Itô process. This representation further helps to solve the principals' problem in case we have infinite number of principals in the sense of mean field game. Finally the mean field formulation is justified by an argument of propagation of chaos.

This paper introduces principal-agent theory and its recent application in science and technology studies. First, the text describes the theory itself and its developments in economics and political science. The paper examines the way these disciplines have used it to explain research related issues. Then, it presents specific applications of the theory to science and technology studies. The paper suggests that the Principal-Agent Theory is related to classical theories of the discipline, of which it is sometimes merely a formalization. It proposes, finally, that the theory weaknesses are due to its misuse and its limited development rather than to its real potential, judging by its successful application in other social sciences. ; Este trabajo presenta la Teoría de Principal-Agente y la forma en que se ha establecido en los últimos años en los estudios de ciencia y tecnología. Para ello describe, primero, la propia teoría y la forma en que la han desarrollado la economía y la ciencia política. El trabajo revisa el modo en que estas disciplinas la han utilizado para explicar problemas relacionados con ciencia y tecnología o que los tocan lateralmente. Después se ocupa de las aplicaciones concretas en los llamados estudios de ciencia y tecnología. El artículo propone que la teoría se relaciona con las teorías clásicas de la disciplina, de las que a veces es sólo una formalización. Como propone, por fin, que las debilidades de la teoría se deben antes a su mal uso y a su escaso desarrollo que a sus posibilidades reales, a juzgar por su éxito en otras ciencias sociales.

This paper analyses principal-agent contracts when the risk-averse agent's action generates information that is not directly verifiable but is used to make a risky decision in a formulation more general than previously studied. It focuses on the impact on the decision made and the contract used, establishing a necessary and sufficient condition for the principal to gain by distorting decisions away from what is efficient and conditions under which there is no conflict between incentives to make decisions and to take action. Applications to investing in a risky project and bidding to supply a good or service illustrate those results.
