The first looks at the incentives of programmers to participate in open source projects. The second considers the business models used by profit-making firms in the open...

We present a technique for locating both an upper and a lower bound on equilibrium points of supermodular games by looking only at the first derivatives of the payoff functions at points of disequilibrium. This technique is useful for characterizing equilibria of games when the closed form...

By initially selling goods only in bundles and subsequently selling unsold units individually, a multiproduct seller can create a buying frenzy in which his profit is higher than it would be if he sold all units individually at their market clearing prices. In this frenzy, high-valuation...

This paper shows how rules restricting common ownership of multiple media outlets affect both the magnitude and diversity of the ideological content of programming. While in most industries the assumption that firms maximize profits is quite reasonable, we assume that media owners derive utility...
