Following Bernheim and Whinston (1990), this paper addresses the effects of multimarket contact on firms ability to collude in repeated oligopolies. Managerial incentives, taxation, and financial market imperfections tend to make firms objective function strictly concave in profits and market...

We model networks of relational (or implicit)contracts, exploring how sanctioning power and equilibrium conditions change under different network configurations and information transmission technologies. In our model, relations are the links, and the value of the network lies in its ability to...

The traditional avoidance literature undeservedly neglects tax base distribution as a factor affecting the avoidance price, and generally assumed to be equal to the avoidance cost. In reality, avoidance providers are usually either high-skilled specialists or insiders. The strong collusion thus,...

We study an asymmetric information model in which two firms are active on a market where buyers only observe the average quality supplied. Quantities and cost structures are exogenously given and firms compete in quality. Before choosing their qualities, they bargain over a perfectly enforcable...

Two firms produce different qualities at possibly different, constant marginal costs. They compete in quantities on a market where buyers only observe the average quality supplied. The model is a generalization of the standard Cournot duopoly, which corresponds to the special case where the two...

We find that contrary to common perception, cooperation as equilibrium of the infinitely repeated discounted prisoner's dilemma is in many relevant cases not very plausible, or at least questionable: for a significant subset of the payoff-discount factor parameter space cooperation equilibria...

A hierarchically structured rent-seeking contest may be associated with lower equilibrium expenditure than a corresponding flat contest. In this chapter we discuss how this fact may be used to explain the structure of organizations such as firms, including why firms commonly have outside owners.

A purchaser/provider split together with output- based reimbursement were recently introduced by several Swedish county councils. These changes have been motivated by arguments of efficiency and consumer choice. This paper tests the null hypothesis that hospital services are provided as...

The paper analyses how cooperation in a repeated social game may help to sustain cooperation in a "linked" repeated production game. We show that this may happen a)because of available "social capital", defined as the slack of punishment power present in the social repeated game, b) because,...
