 The Origin of Information in Football Betting Markets

 

In this paper we propose that there are two types of bookmakers in football betting markets, which we label book-balancing and position-taking bookmakers. We argue that their operational differences hold the key to the evolution of prices within the aggregate marketplace. Book-balancing bookmakers provide online services only, and operate a high-turnover, low-margin business, and do not restrict trade with sophisticated bettors. Position-taking bookmakers, conversely, operate both physical world betting shops and operate a high-margin, low-turnover business, whilst actively maintaining a clientele of unsophisticated customers. We analyse a unique longitudinal dataset relating to the odds posted by a leading book-balancing and a leading position-taking bookmaker for six major European football leagues over the 2012-13 season. The book-balancing bookmaker charges a consistently lower transaction cost, and changes their odds five times more frequently than the position-taking bookmaker, indicative of active management of the book to avoid liabilities from sophisticated clientele. The prices from the book-balancing bookmaker are more efficient predictors of match outcomes than the prices from the position-taking bookmaker. Our conclusion is that prices in football betting markets are set on the demand side, rather than the supply side as has previously been hypothesised.
