So You Discovered an Anomaly ... Gonna Publish It? An Investigation Into the Rationality of Publishing a Market Anomaly

If publishing an anomaly leads to the dissipation of its profitability, a notion that has mounting empirical support, then publishing a highly profitable market anomaly seems to be irrational behavior. This paper explores the issue by developing and empirically testing a theory that argues that publishing a market anomaly may, in fact, be rational behavior. The theory predicts that researchers with few (many) publications and lesser (stronger) reputations have the highest (lowest) incentive to publish market anomalies. Employing probit models, simple OLS regressions, and principal component analysis, we show that (a) market anomalies are more likely to be published by researchers with fewer previous publications and who have been in the field for a shorter period of time and (b) the profitability of published market anomalies is inversely related to the common factor spanning the number of publications the author has and the number of years that have elapsed since the professor earned his Ph.D. The empirical results suggest that the probability of publishing an anomaly and the profitability of anomalies that are published are inversely related to the reputation of the authors. These results corroborate the theory that publishing an anomaly is rational behavior for an author trying to establish his or her reputation.
