Ex-dividend Day Pricing in New Zealand

Controversy continues over the question of tax clientele effects in the pricing of shares that pay dividends. The empirical results remain inconclusive, with variations in testing methods and sample formation the probable causes of much of the variation in outcomes. This study focuses on testing for the presence of a tax clientele effect consistent with prior tests for the same effect using a sample from a particular tax regime period in New Zealand in which companies could pay either or both taxable and non-taxable dividends. The results are generally consistent with the presence of a tax clientele effect in the New Zealand market for the time period, while providing essentially no support for the short term trading hypothesis.
