This paper investigates whether the sentimental preferences of investors influence market efficiency. We use a betting exchange market environment to analyze the influence of sentimental bettors on market efficiency in 2,333 soccer matches played between 2006-2014 during the last three hours of...

We compare the properties of betting market odds set in two distinct markets for a large sample of European soccer matches. We confirm inefficiencies in the traditional market for bets on a home win, an away win or a draw as found in previous studies such as Angelini and De Angelis (2019), in...

Sports betting markets can be considered strongly efficient if expected returns on all possible bets on an event are equal. If this form of efficiency holds, then there is a direct mapping from betting odds into probabilities of outcomes of sporting events. We compare two regression-based...

Betting lines and scores from the 2009/10 college basketball season for 169 mid-major and major colleges are used to verify the efficiency hypothesis for the betting-market analogy to the CAPM-based market model. As in that model, the portion of the variance in the spreads that is unexplained by...

Betting strategies based on the presence of home-underdog bias in the NFL have been shown to produce returns in excess of those predicted by market efficiency in some situations. Dare and Dennis (2011) attribute this bias to bettors underestimating the scoring ability of home underdogs. Using a...

Previous studies of the National Hockey League (NHL) betting market claim a general movement towards efficiency over the last two decades. These studies, however, assume a homogenous betting market with regards to the time of year in which bets are placed. Differences in available...

The favourite-longshot bias is estimated for bookmaker odds from 9,006 UK Flat races, and compared to the bias evident in a sample of betting exchange odds from 6,000 races during the same period. The results are compared to similar studies of bias in Tote odds and US pari-mutuel odds. It is...

In this paper, we test two different kinds of bias; the favorite-longshot/favorite-underdog and the home team bias, and distinguish between the two, using a distinctive feature of the Australian Football League (AFL), that many games are played on neutral grounds. This is the first empirical...
