This paper studies the effect of investor-specific differentialdividend taxation on the dynamics of equilibrium security pricesand allocations. In order to deal with the inherent Paretoinefficiency of such an equilibrium as well as the preclusion oftax arbitrage, we construct a continuous-time equilibrium via arepresentative investor with state-dependent utility. Investorsdiffer in their pricing of risk, inducing investor-specificconsumption-based CAPMs, with differential taxation appearing asan additional factor. The interest rate, stock price, andconsumption dynamics are also impacted. Under logarithmicpreferences, risk is transferred from the higher-taxed to thelower-taxed investor, and the interest rate decreases tocounteract extra precautionary savings against this suboptimallyshared risk. Numerical analysis reveals further tax rate,time-to-horizon, and dividend risk effects on equilibriumquantities. For most wealth allocations, the stock returnvolatility is increased above the no-tax benchmark.  相似文献

This paper examines the risks and returns of Latin American stocks following American depository receipt (ADR) listings in U.S. equity markets and finds no systematic change in their volatility. This finding differs from previous results for ADR introduction on European and Asian stocks, although it is consistent with several prior findings on international stock listings. Importantly, it supports the predictions of Domowitz, Glen, and Madhavan's 1998 model of international cross-listings. This model predicts that the effects of such listings will differ across stocks because the net effect is indicative of the specific trade-off for each individual stock between benefits of enhanced intermarket competition and costs stemming from the diversion of information-linked orders out of the domestic market.  相似文献

This paper investigates the stock volatility–volume relation in the Korean market for the period 1995–2001. Previous research examined the impact of liberalization on the Korean stock market up to the period before the financial turmoil in 1997 although the crucial measures of the liberalization were introduced after the crisis under the International Monetary Fund program. One of the major features of the reformation was the financial opening to foreign investors. In this study the ‘total’ trading volume is separated into the domestic investors’ and the foreign investors’ volume. By doing this the information used by two different groups of traders can be separated. Further, in addition to the absolute value of the returns and their squares we use the conditional volatility from a GARCH-type model as an alternative measure of stock volatility. The following observations, among other things, are noted about the volume–volatility causal relationship. First, for the entire period there is a strong bidirectional feedback between volume and volatility. In most cases this causal relationship is robust to the measures of volume and volatility used. Second, volatility is related only to ‘domestic’ volume before the crisis whereas after the crisis a bidirectional feedback relation between ‘foreign’ volume and volatility begins to exist. In other words, ‘foreign’ volume tends to have more information about volatility in recent years, which suggests the increased importance of ‘foreign’ volume as an information variable.   相似文献

本文研究对冲基金在衍生产品(主要是认股权证)提供的高效率低成本套利工具的条件下,如何使香港地区股市以往长时间累积的系统风险分散到各个时段,使股市的长期(年度)波幅变小,短期(月份)波幅变得均匀。犹如在股市这个大系统下加入一个负反馈回路,使原来只有正反馈回路、很容易进入震荡状态、失去控制的股市,变成稳定运行的系统,避免泡沫的产生,达到提高市场效率的目的。此外,我们以香港地区股市(恒生指数为主)波动为实证数据进行分析,其结果证实了上面的结论。  相似文献
