A review of these studies reveals. However, a widespread misuse of dummy regression which is very likely to result in misleading implications in theory and model building and in guiding managerial action-i.e. the use of standardized weights as measures of effect instead of unstandardized ones. Five out of 14 studies do not mention which type of weight was used, whereas only Alegre and Garau(2011) and Mikulic and Prebrzac(2011) explicitly report use of the unproblematic (unstandardized) type. This brief note thus aims to raise awareness about this problem and to explain why standardized weights should generally be avoided when analyzing variable effect size with dummy regression. In elaborating the problem, the methodological foundations of dummy regressions in asymmetry assessments are first briefly discussed, followed by an illstrative case example that empirically demonstrates the problem and its implication.
