We experimentally examine the impact of buyer concentration on the pricing of a monopolist. In our experimental markets, a monopolist faces either two or four buyers. Markets with two buyers achieve significantly lower prices, sometimes below competitive levels, than those with four buyers. We...

Although much research has been devoted to the impact of seller structure on market outcomes, considerably less is known about the influence of buyer structure. We examine the impact of buyer concentration on the pricing of a monopolist. Markets with both two and four buyers achieve prices well...

We infer unobserved strategies from the observed actions of buyers in posted-offer market experiments to evaluate their effectiveness against a monopolist. While the strategies of one-quarter of the buyers in our experiments correspond to the game-theoretic prediction of passive price-taking,...

We introduce a Bayesian method to infer repeted-game strategies in the form of if-then statements that best describe individuals' observed actions. We apply this method to buyer behavior in posted-offer market experiments. While the strategies of one-quarter of the buyers in our experiments...

Cooperation in real-world dilemmas takes many forms. We introduce a class of two-player games that permits two distinct ways to cooperate in the repeated game. One way to cooperate is to play cutoff strategies, which rely solely on a player's private value to defection. The second cooperative...

Sometimes cooperation between two parties requires exactly one to cede to the other. If the decisions whether to cede are made simultaneously, then neither or both may acquiesce leading to an inefficient outcome. However, inefficiency may be avoided if a party can wait to see what the other...

We report the results of a field experiment on honesty conducted on 427 Israeli soldiers fulfilling their mandatory military service. Each soldier rolled a six-sided die in private and reported the outcome to the unit's cadet coordinator. For every point reported, the soldier received an...

We conduct a field experiment on 427 Israeli soldiers who each rolled a six-sided die in private and reported the outcome. For every point reported, the soldier received an additional half-hour early release from the army base on Thursday afternoon. We find that the higher a soldier's military...

We introduce a two-player, binary-choice game in which both players have a privately known incentive to enter, yet the combined surplus is highest if only one enters. Repetition of this game admits two distinct ways to cooperate: turn taking and cutoffs, which rely on the player's private value...

The public finance literature demonstrates the equivalence between consumption and labor-income (wage) taxes. We introduce an experimental paradigm in which individuals make real labor-leisure choices and spend their earned income on real goods. We use this paradigm to test whether a...
