Haavelmo's seminal 1943 paper is the first rigorous treatment of causality. In it, he distinguished the definition of causal parameters from their identification. He showed that causal parameters are de fined using hypothetical models that assign variation to some of the inputs determining...

By the well established tournament literature, incomplete information regarding the employees? productivity is essential for the rationalization of (efficiency-enhancing) tournaments. In this paper we propose an alternative rationalization of tournaments focusing on a fully informed principal...
