Do Independent Directors Improve Firm Value? Evidence from the Great Recession

The literature offers no clear evidence on the effect of independent directors on firm value. We argue that, during stressful times, firms may need more and better expert advice to navigate a crisis. Outside independent directors can provide such advice. So, the role of independent directors may be more pronounced during a stressful time. Consistent with this notion, we find that independent directors significantly improved firm value during the Great Recession of 2008. Specifically, a rise in the percentage of independent directors by one standard deviation would have improved firm value by 4.29% during the Great Recession. Outside the crisis period, however, our results do not show that independent directors increase firm value. Further analysis confirms the results, including random‐effects regressions, propensity score matching, instrumental‐variable regressions, as well as falsification tests. Our results are crucial as they demonstrate that the role of independent directors is different during stressful times than it is during normal times.     

Price Movers on the Stock Exchange of Thailand: Evidence from a Fully Automated Order‐Driven Market

This study examines which trade sizes move stock prices on the Stock Exchange of Thailand (SET), a pure limit order market, over two distinct market conditions of bull and bear. Using intraday data, the study finds that large‐sized trades (i.e., those larger than the 75th percentile) account for a disproportionately large impact on changes in traded and quoted prices. The finding remains even after it has been subjected to a battery of robustness checks. In contrast, the results of studies conducted in the United States show that informed traders employ trade sizes falling between the 40th and 95th percentiles ( Barclay and Warner, 1993 ; Chakravarty, 2001 ). Our results support the hypothesis that informed traders in a pure limit order market, such as the SET, where there are no market makers, also use larger‐size trades than those employed by informed traders in the United States.     

Who knows more about future currency volatility?

We use four currency pairs from October 1, 2001 to September 29, 2006 to compare the predictive power of the implied volatility derived from currency option prices that are traded on the Philadelphia Stock Exchange (PHLX), Chicago Mercantile Exchange (CME), and over‐the‐counter market (OTC). Among the competing implied volatility forecasts, OTC‐implied volatility subsumes the information content of PHLX‐ and CME‐implied volatility. Consistent with extant studies our result also shows that the implied volatility provides more information about future volatility–regardless of whether it is from the OTC, PHLX, or CME markets–than time series based volatility. © 2009 Wiley Periodicals, Inc.
