Bookmakers sell claims to bettors that depend on the outcomes of professional sports events. Like other financial assets, the wisdom of crowds could help sellers to price these claims more efficiently. We use the Wikipedia profile page views of professional tennis players involved in over ten...

We contribute to the discussion on betting market efficiency by studying the odds (or prices) set by fifty-one online bookmakers, for the result outcomes in over 16,000 association football matches in England since 2010. Adapting a methodology typically used to evaluate forecast efficiency, we...

It has been established in the economics literature that competitive outcomes can be well predicted by the aggregate salaries of the contesting participants. In this paper we use this idea to construct a forecast test to evaluate a novel, and hitherto unevaluated source of wage data. If the...

We investigate rivalry as a driver of unethical behavior. We first distinguish it from general competition, both conceptually and in terms of its consequences for behavior. Then, across four experiments and one archival study, we find evidence that rivalry fuels greater unethical behavior than...

A common finding in laboratory studies is that subjects anchor on irrelevant initial cues when valuing assets. We run a field experiment to examine whether this heuristic can be exploited to manipulate prices in real markets. We provide early quotes in a series of horse race betting markets, and...

We conduct a field experiment to see if market liquidity has a causal effect on price efficiency and, if so, why. We randomly provide liquidity in certain horse race betting markets, and not in others. We find that prices in treated markets are indeed more efficient than prices in control...
