Financial Reforms and Time-Varying Microstructures in Emerging Equity Markets

Abstract

This paper seeks to investigate the impact of financial reforms on time-varying microstructures in emerging equity markets. We develop annual indicators of informational efficiency, market volatility and transaction costs, using daily data for a panel of 28 emerging markets over the 1996-2007 period. We then analyze the impact of insider trading regulations, trading system automation and accounting standardization on microstructures through a set of panel regressions controlling for financial development and simultaneous reforms. Our results suggest that emerging market microstructures are affected by economic and political context, are strongly related to one another and depend on specific institutional reforms.
