Recent research describes a bias in the pricing of the home field advantage in the betting market on National Football League games with a national focus (Monday night and playoff games). Home teams, especially home team underdogs, win at a rate sufficient to reject both the unbiased forecast and absence of profit opportunities versions of market efficiency. This paper extends the examination of the pricing of the home field advantage, particularly in games with a national focus, to the point spread betting market on National Basketball Association games and the fixed odds betting market on Major League Baseball games. Contrary to the football results, we find little evidence of a mispricing of the home field advantage in either regular season or playoff games in both basketball and baseball. Further, betting on all home teams is never profitable in either league. Additionally, the paper examines the latest three football seasons and finds no mispricing in games with a national focus in this out-of-sample period. We conclude that these markets are, in general, efficient.
