Underdogs Are Man’S Best Friend: A Test Of Football Market Efficiency, Ladd Kochman, Randy Goodwin
Underdogs Are Man’S Best Friend: A Test Of Football Market Efficiency, Ladd Kochman, Randy Goodwin

Two mechanical betting rules that had exposed biases in previous studies were applied to National Football League games for the five consecutive seasons ending with the 2003 Super Bowl. Although bets on home teams produced only break-even results, wagers on underdogs posed a serious challenge to the efficient market hypothesis. One possible explanation is that favorites are no less “public” in the minds of bettors than IBM, GE, and the like are public in the minds of investors and may therefore be the victims of inflated expectations and point spreads.

GDP Database of the Mexican States (1940-2013) at constant prices of 1993. They were estimated as in German-Soto (2005) for the 1940-1992 period. Between 1993 and 2006 they are official figures by INEGI: Sistema de Cuentas Nacionales. Since 2006 the base changed to 2008, therefore figures published in this database for 2007 to 2013 were estimated applying the rate of growth of the gross state product in base 2008 (of those years) on series at constant prices of 1993 since 2006. As a result, we have a homogenous database for the period 1940-2013 in prices of 1993. A project to …

This article investigates the use of teacher value-added estimates to assess the distribution of effective teaching across students of varying socioeconomic disadvantage in the presence of classroom composition effects. We examine, via simulations, how accurately commonly used teacher value-added estimators recover the rank correlation between true and estimated teacher effects and a parameter representing the distribution of effective teaching. We consider various scenarios of teacher assignment, within-teacher variability in classroom composition, the importance of classroom com- position effects, and the presence of student unobserved heterogeneity. No single model recovers without bias estimates of the distribution parameter in all the scenarios …
