This paper studies how the strategic interaction between a specialized communication platform and two firms, competing in prices and advertising efforts, determines the equilibrium advertising fee and the pattern of competition between sellers. We show that the link between information and price...

In standard Bertrand model duopolists compete on perfect markets. However, not many markets are perfect. In fact most of the markets have certainstructure, and this structure is known to producers. We describe the marketorganization by modeling consumer-producer networks and demonstrate thatif...

We present a model of imperfect price competition where not all firms can sell to all consumers. A network structure models the local interaction of firms and consumers. We find that aggregate surplus is maximized with a fully connected network, which corresponds to perfect competition, and...

We consider an oligopoly of firms that compete on price. Firms produce a non-stochastic output, insurance coverage, which is sold before the true cost is known. They behave as if they were risk-averse for a standard reason of costly external finance. The model consists in a two-stage game. At...

In this paper we analyse the endogenous order of moves in a mixed duopoly for differentiated goods. Firms choose whether to set prices sequentially or simultaneously. The private firm maximises profits while the public firm maximises the weighted sum of the consumer and producer surpluses...

In this paper we analyze the strategic decisions of the government, the incumbent and the pirate in a market where the good is piratable. We show that deterred or accommodated piracy can occur in equilibrium, but pure monopoly cannot occur for any anti-piracy policy. We also show that the...

Az élelmiszerek fogyasztói árindexe évek óta az inflációt meghaladó ütemben nő, az élelmiszer-kiskereskedelmi egységek éleződő versenye ellenére. A verseny erősségét az élelmiszer-kiskereskedelem kiegyenlített versenystruktúrája eredményezi, amit az első hat piaci...

This paper analyzes the relationship between competition and R&D cooperation with universities and competitors. Our simple model predicts that more competitors reduce the incentives for horizontal cooperation as it diminishes the gains from “collusion”. Assuming that the value of synergies...

Does price competition exist in the mutual fund industry? If so, is it too weak to prevent anticompetitive pricing by investment advisors to retail investors?

We assess the extent to which specialist doctors respond to local competition when setting prices (including extra-billings) in a fee-for-service system. We use an exhaustive panel data set to estimate physician reaction functions, exploiting exogenous changes in medical density and labor supply...
