The Granger causality procedure is used to assess the dynamics of market efficiency of 17 international stock indices. These indices are based on relatively smaller firms. The reference of market efficiency is a stock index, from the same economy, which is based on relatively larger firms. There...

This examination of the turn of the month (TOM) and turn of the year (TOY) effects in 50 international stock indices, for the period 1994--2006, characterises the degree that the effects are influenced by: (i) the gross domestic product of the economy, (ii) the sign of the return on the prior...

This review of the SAD hypothesis of Kamstra et al. (2003), hereafter KKL (2003), isolates four new problems. First, the KKL (2003) statistical model does not test the KKL (2003) SAD hypothesis. Second, KKL (2003) do not properly interpret their results. Third, KKL (2003) incorrectly specify the...

Kamstra et al. (2003, 2009, 2012) offer a seasonal affective disorder hypothesis to explain variations in the daily returns of stock indices. We examine Kamstra et al. (2012) new variable called SAD onset/recovery. The analysis reveals concerns for the validity of the SAD hypothesis.

Miller (2009a) derives a weighted average cost of capital for the special case where the cash flows to equity and the cash flows to debt are annuities. The paper attracts debate. We show that the weighted average cost of capital is redundant in a world where interest paid is not tax deductible....

This study uses an alternative model specification to re-examine the influences of the new moon and the full moon on the daily returns of 62 international stock indices for the period 1988 to 2008. The fixed effects panel model incorporates the prior day effect and two calendar anomalies, i.e.,...
