This paper provides a thorough analysis of oligopolistic markets with positive demand-side network externalities and perfect compatibility. The minimal structure imposed on the model primitives is such that industry output increases in a firm's rivals' total output as well as in the expected...

This paper analyzes the effect of bank participation in the equity of a firm on the competitiveness of the credit market. Using an auction model of bank competition it is shown that an equity stake of one bank is increasing its market power in the market for credits to this firms. The...

With an auction model of bank competition, the relationship between the number of banks in a market, the quality of the firms and the banks’ effort to carry out creditworthiness tests is analyzed. It is shown that, if the cost of information acquisition is taken into account, welfare and the...

The paper analyzes the repeated interaction between a bank and a firm. A simple two period model is constructed, which explains several features of a credit relationship: It shows why bank finance is available for firms which cannot obtain bond financing, why credit contracts contain a .Material...

The intensity of credit screening in a banking duopoly is endogenized under two different assumptions. In the first case each bank observes its competitior’s investment in information acquisition before making a credit offer. In the second case information acquisition and bidding in the credit...

This paper compares Cournot and Bertrand equilibria with mixed products, linear demand and cost functions. It is found that a firm's price (output) need not be higher (lower) in Cournot equilibrium. However, given any number of firms and a mixture of complement and substitute products, every...

This paper considers three linear asymmetric oligopoly models with (i) a representative consumer, (ii) horizontal differentiation and (iii) vertical differentiation. We show that firms could maximize the joint-profit only based on private and aggregate information. They can choose the...

This paper studies the incentives and the welfare effect of sharing firm-specific information in asymmetric Cournot and Bertrand oligopoly with mixed substitute and complement goods. Revealing firm-specific cost information is the dominant strategy in Cournot oligopoly, while concealing is so in...

This paper studies the impact of learning by doing on shakeouts in monopolistic competition. Firms have different initial costs and set prices to maximize current profits in each period. Although all firms make positive profits at the beginning and grow for a certain period of time, shakeouts...

This paper studies an auction model in which one of the bidders, the insider, has better information about a common component of the value of the good for sale, than the other bidders, the outsiders. Our main result shows that the insider may have incentives to disclose her private information...
