Note(s): LNAGE denotes the natural logarithm of a firm's age. LOCKUP denotes the dummy variable of the lock-up period whereby the IPOs issued under the 180-day lock-up regime (effective from the year 2009) are represented by “1”, whereas “0” is for the IPOs issued under the 360-day lock-up regime. The asterisks ***, ** and * signify significance at 1%, 5% and 10%, respectively. The quantile regression estimation uses the alternative Epanechnikov kernel function and Hall–Sheather's bandwidth
