“…In contrast to previous work computing volatility over a fixed time period such as 20 years or 5 years (e.g., Acemoglu et al, 2003;Kose et al, 2003, Bekaert et al, 2006Yang, 2008), this paper measures volatility over a five-year moving window. Such a moving standard deviation measure has been used in studying the stock market volatility (see, for example, Arestis et al, 2001), and though not perfect, serves our purpose well since we intend to compare the differences before and after the liberalization on a yearly basis and countries do not liberalize at the same time.…”
