A Monte Carlo experiment is conducted to compare power properties of alternative tests for the martingale difference hypothesis. Overall, we find that the wild bootstrap automatic variance ratio test shows the highest power against linear dependence; while the generalized spectral test performs...

This paper proposes a new method of interval estimation for the long run response (or elasticity) parameter from a general linear dynamic model. We employ the bias- corrected bootstrap, in which small sample biases associated with the parameter estimators are adjusted in two stages of the...

This study measures the degree of short-horizon return predictability of 50 international equity markets and examines how its variation is related to the indicators of equity market development. Two multiple-horizon variance ratio tests are employed to measure the degree of return...
