We develop a theoretical model in which firms may choose multiple banking relationships to reduce the risk that financing will be denied by "relationship banks" should the latter experience liquidity problems and refuse to roll over lines of credit. The inability to refinance from relationship...

This paper studies the restructuring of non-marketable debt, when the number of creditors is arbitrary, and there is asymmetric information. With multiple creditors, debt forgiveness has the character of a public good. As for the case of private provision of a public good, mechanism design...

In a duopoly where two firms' products are differentiated both, horizontally and vertically, introduction of a quality standard affects equilibrium quality levels of both firms. The effects, furthermore, depend upon consumers being or not perfectly informed about qualities. Qualities are...

The present note shows that "innocuous" Minimum Quality Standards, namely standards that are below the lowest quality level observed in the market, may have effects on equilibrium outcomes. In particular this is true in a duopoly where one high quality firm invests in R&D to lower its cost of...

The literature so far has analyzed the effects of Minimum Quality Standards in oligopoly, using models of pure vertical differentiation, with only two firms, and perfect information. We analyze products that are differentiated horizontally and vertically, with imperfect consumers information,...

We study reactions to entry in a Cournot model, contrasting the case where firms are endowed with unchangeable technologies against that where technologies are flexible. By the latter we mean that firms can change the installed production technique at zero cost (fully flexible technologies). We...

In markets where product quality is important, more than one characteristic is usually necessary to define product quality and the amelioration of the goods characteristics is usually costly. Then, properties of production technologies, in particular if they exhibit economies or diseconomies of...

In a model of behavior-based price discrimination (BBPD), we argue that sellers may have discretionary power to let buyers decide whether to be identified (e.g., creating an account) or remain anonymous (no account creation). The price equilibria generate a more fragmented market segmentation...

This paper is about technology choices in a differentiated oligopoly. The main questions are: whether the position in the product space affects the choice of technology, how changes in fixed costs affect price outcomes, the strategic responses to policy interventions. The industry is an...
