While many studies have documented deviations from the Law of One Price in international settings, evidence is scarce on the extent to which consumers take advantage of price differentials and engage in cross border shopping. We use data from 287 Swedish municipalities to estimate how responsive...

The effect of trade liberalization on the spatial concentration of economic activities is not straightforward. It has, on the one hand been widely argued that protectionism increase spatial concentration when firms locate close to the main domestic markets, but it has also been argued that trade...

We propose a political theory for the slow adoption of technology in sports and other contests. We investigate players’preferences for new technology that improves contest accuracy. Modeling accuracy as the elasticity of "production" in a standard Tullock contest, we show that players may be...

Game theory is usually difficult to test precisely in the field because predictions typically depend sensitively on features that are not controlled or observed. We conduct one such test using field data from the Swedish lowest unique positive integer (LUPI) game. In the LUPI game, players pick...

Sets closed under rational behavior were introduced by Basu and Weibull (1991) as subsets of the strategy space that contain all best replies to all strategy profiles in the set. We here consider a more restrictive notion of closure under rational behavior: a subset of the strategy space is...

We model a player's uncertainty about other player's strategy choices as probability distributions over their strategy sets. We call a strategy profile robust to strategic uncertainty if it is the limit, as uncertainty vanishes, of some sequence of strategy profiles in each of which every...

This paper extends the concept of weak renegotiation-proof equilibrium (WRP) to allow for costly renegotiation and shows that even small renegotiation costs can have dramatic effects on the set of equilibria. More specifically, the paper analyzes the infinitely repeated Bertrand game. It is...

Two principals simultaneously appoint one agent each and decide how much power to give to their agents. The agents' task is to bargain over the provision of a public good. Power here means the right to decide the own side's provision if negotiations break down. In equilibrium the principals...

We find that contrary to common perception, cooperation as equilibrium of the infinitely repeated discounted prisoner's dilemma is in many relevant cases not very plausible, or at least questionable: for a significant subset of the payoff-discount factor parameter space cooperation equilibria...
