There are many situations in which a customer's proclivity to buy the product of any rm depends heavily on who else is buying the same product. We model these situations as non-cooperative games in which rms market their products to customers located in a \social network". Nash Equilibrium (NE)...

There are many situations in which a customer’s proclivity to buy the product of any firm depends not only on the classical attributes of the product such as its price and quality, but also on who else is buying the same product. Under quite general circumstances, it turns out that...

We consider a communications network in which users transmit beneficial information to each other at a cost. We pinpoint conditions under which the induced cooperative game is supermodular (convex). Our analysis is in a lattice-theoretic framework, which is at once simple and able to encompass a...

This note demonstrates how performance measure congruity and noise determine an agency’s total surplus within an linear agency framework with multiple tasks. It provides a decomposition of agency costs, leading back to a congruity index previously proposed in the literature. In addition,...

We develop a model to show that cartels that produce goods with lower durability are easier to sustain implicitly. This observation gen- erates the following results: 1) implicit cartels have an incentive to pro- duce goods with an inefficiently low level of durability; 2) a monopoly or explicit...
