July 1999Japan's Big Bang and the Transformation of Financial Markets
with Takatoshi Ito: w7247

Intra-day data are analyzed with the following results: (1) Holding constant the effects of volume and volatility, the deregulation was associated with a convergence of Japanese quoted spreads toward those of other banks. (2) Modeling the persistence in volatility reveals that deregulation lowered conditional volatility.

Having eliminated public information as the cause, we exploit the volatility pattern over the whole day to discriminate between the two alternatives: private information and pricing errors. Three key results support the predictions of private-information models. First, the volatility U-shape flattens: greater revelation over lunch leaves a smaller share for the morning and afternoon. Second, the...
