We analyse consumers' search and purchase decisions on an Internet platform. Using a rich dataset on all adverts posted and transactions made on a major French Internet platform (PriceMinister), we show evidence of substantial price dispersion among adverts for the same product. We also show...

The compromise effect refers to individuals' tendency to choose intermediate options. Its existence has been demonstrated in a large number of hypothetical choice experiments. This paper uses field data from a specialties restaurant to investigate the existence and strength of the compromise...

We experimentally test Kőszegi and Rabin's (2006, 2007) theory of reference-dependent preferences in the context of price expectations. In an incentivised valuation task, participants are endowed with a mug and provide their willingness to accept (WTA) to sell it. We manipulate the sale price...

Do people only reject interference and keep control in order to affect the outcome? We find that 20% of subjects reject unrequired help and insist on their solution to a problem - although doing so is costly and does not change the result. We tease out the motives by varying the information...

In Europe, the competence for social security and the right to levy income tax lie with the country of employment in cross-border matters. This has two disadvantages. First, the Employment Principle distorts active persons' choice of place of work. Second, the employment-based regulation of...

We examine the efficiency properties of labor taxation. A spatial model of an economy is introduced whose key feature is a new approach to restricted labor mobility. We characterize the efficient allocation of labor and properties of a decentralized equilibrium. An efficient allocation of labor...

We investigate the direct and long-run effects of fertility on employment in Europe estimating dynamic models of labor supply under different assumptions regarding the exogeneity of fertility and modeling assumptions related to initial conditions, unobserved heterogeneity and serial correlation...

This study examines whether viewers of the popular television show, American Idol, are racially biased. I find strong evidence for same-race preferences, in particular among black viewers. Featuring more black contestants attracts more black households to tune in to watch the show. And, with...

While most empirical analysis of prediction markets treats prices of binary options as predictions of the probability of future events, Manski (2004) has recently argued that there is little existing theory supporting this practice. We provide relevant analytic foundations, describing sufficient...

We provide a direct test of the role of social preferences in voluntary cooperation. We elicit individuals' cooperation preference in one experiment and make a point prediction about the contribution to a repeated public good. This allows for a novel test as to whether there are "types" of...
