The author studies two-firm location games on graphs. Earlier work analyzes two-firm location games on a line or a circle, and all examples given possess pure Nash equilibria. The author produces an example of a graph with no pure Nash equilibria and also a general class of graphs that do...

A rule for 3-way division of profits based on peer evaluation reports is impartial if the calculation of each partner's share ignores her report, exact if it never allocates more or less than the profit to be shared, and consensual if it respects evaluations when the partners' reports are in...

We find that collusion can only be profitable if a coalition contains more than half of all players. This result holds for location games played...

This paper studies welfare tradeoffs in two-sided, one-to-one matching markets. We begin by providing theoretical upper bounds on a utilitarian price of stability, and show that these bounds vary with the composition of participants’ ordinal preference lists. We then turn to simulation...
