    This paper apportions responsibility for inefficiency in a market for state contingent claims between market makers and traders. We specifically examine the origins of a frequently observed distortion in the market for bets in horseraces - the favorite- longshot bias. Previous studies rationalise the bias in terms of traders' (bettors) or market makers' (bookmakers) behaviour. Employing hitherto unavailable data we conduct a parallel logistic analysis of parimutuel and bookmakers markets, which offers an unequivocal basis for identifying the origin of the bias

    This paper seeks to offer new insights into the behavioral origins of the 'favourite-longshot' bias - an established feature of betting markets, whereby longshots win less often than the subjective probabilities imply and favourites more often. This study analyses a new data source which offers detailed information for a large sample of recent UK horseraces on decision-making behavior within the parimutuel and the parallel bookmaker-based betting markets
