We show that even in very simple oligopolies with differential information a (Bayesian) Cournot equilibrium in pure strategies may not exist, or be unique. However, we find sufficient conditions for existence, and for uniqueness, of Cournot equilibrium in a certain class of industries. More...

This paper analyzes the entry of new products into vertically differentiated markets where an entrant and an incumbent compete in quantities. The value of the new product is initially uncertain and new information is generated through purchases in the market. We derive the (unique) Markov...

Can debt rescheduling decisions differ in multiple lenders' versus a single lender loan? Do multiple lenders efficiently react to information? We show that the precision of information plays an essential role. Foreclosing by one lender is disruptive so that a lender can rationally wait for the...

Suppliers often make proactive investments in capacity to strategically position themselves to win a contract with a monopolist buyer. Such investments reduce the suppliers' variable costs of serving the buyer's demand. We show that an auction mechanism does not always benefit the...

Biconcavity is a simple condition on inverse demand that corresponds to the ordinary concept of concavity after simultaneous parameterized transformations of price and quantity. The notion is employed here in the framework of the homogeneous-good Cournot model with potentially heterogeneous...
