Abstract

Errors in recorded security prices are a source of misspecification in the market model.If recorded-price errors are sufficiently nonrandom, they result in biased returns and biased and inconsistent estimates of market model regression coefficients.This paper argues that tax-induced flow-supply pressures result in end-of-the-year recorded-price errors that are nonrandom enough to cause the appearance of anomalous turn-of-the-year stock return behavior.Empirical tests of returns and market model regression coefficients during the turn-of-the-year period cannot reject this errors-in-variables explanation of the turn-of-the-year effect.
