Several recent papers argue that contracts provide reference points that affect ex post behavior. We test this hypothesis in a canonical buyer-seller relationship with renegotiation. Our paper provides causal experimental evidence that an initial contract has a highly significant and...

We show that professional soccer players exhibit reference-dependent behavior during matches. Controlling for the state of the match and for unobserved heterogeneity, we show on a minute-by-minute basis that a player breaches the rules of the game, measured by the referee’s assignment of...

This paper studies socially responsible behavior in markets. We develop a laboratory product market in which low-cost production creates a negative externality for third parties, but where alternative production with higher costs mitigates the externality. Our first study, conducted in...

We show that professional soccer players and their coaches exhibit reference-dependent behavior during matches. Controlling for the state of the match and for unobserved heterogeneity, we show on a minute-by-minute basis that players breach the rules of the game, measured by the referee’s...

An auction is externality-robust if unilateral deviations from equilibrium leave the other bidders’ payoffs unaffected. The equilibrium and its outcome will then persist if certain types of externalities arise between bidders. One example are externalities due to spiteful preferences, which...

Do contracts provide reference points that affect ex post behavior? We address this question in a canonical buyer-seller relationship with renegotiation. Our paper provides causal experimental evidence that an initial contract has a highly significant and economically important impact on...

Is competition perceived as a fair procedure? We report data from laboratory experiments where a powerful buyer can trade with one of several sellers. Sellers who feel shortchanged can engage in counterproductive behavior to punish the buyer. We find that the same unfavorable terms of trade...

Philosophers, psychologists, and economists have long argued that certain decision rights carry not only instrumental value but may also be valuable for their own sake. The ideas of autonomy, freedom, and liberty derive their intuitive appeal-at least partly-from an assumed positive intrinsic...
