We present a model of opinion formation where individuals repeatedly engage in discussion and update their opinion in a social network similarly to the DeGroot model. Abstracting from the standard assumption that individuals always report their opinion truthfully, agents in our model may state...

To explain organizational decisions in multistage production processes we assume a production process with one producer and two suppliers of which one is the firm's direct supplier and the other one is the supplier of the supplier. The firm decides only on the organizational form of her direct...

This paper introduces the theory of firm organization under moral hazard into an equilibrium model of international trade with heterogeneous talents and technologies.
