中美资本市场财富效应比较研究

本文从股利支付和资本利得的角度对比分析了中美资本市场财富效应水平,并对其影响因素展开分析。研究发现,我国资本市场财富效应不够显著,A股上市公司虽然具有较高的股利支付倾向,但股利支付率和资本利得属性较弱;股利支付行为迎合监管动机较强,融资分红特征明显,股票股利支付行为具有高送转特征;资本市场估值中枢下移,指数波动性较高,资本利得属性较差。美股上市公司虽然股利支付意愿不及A股,但股利支付率和资本利得属性较强,且上市公司不存在明显的融资分红倾向。基于此,本文从控股股东属性、企业生命周期、管理层侵占行为、宏观经济和资本市场环境四个维度对A股市场财富效应水平展开深入探讨,并从提升公司质量、改善盈利能力、调整投资者结构、加强市场建设、优化股利监管制度五方面提出了改善我国资本市场财富效应的政策建议。     

Consumption, Aggregate Wealth, and Expected Stock Returns

This paper studies the role of fluctuations in the aggregate consumption–wealth ratio for predicting stock returns. Using U.S. quarterly stock market data, we find that these fluctuations in the consumption–wealth ratio are strong predictors of both real stock returns and excess returns over a Treasury bill rate. We also find that this variable is a better forecaster of future returns at short and intermediate horizons than is the dividend yield, the dividend payout ratio, and several other popular forecasting variables. Why should the consumption–wealth ratio forecast asset returns? We show that a wide class of optimal models of consumer behavior imply that the log consumption–aggregate wealth (human capital plus asset holdings) ratio summarizes expected returns on aggregate wealth, or the market portfolio. Although this ratio is not observable, we provide assumptions under which its important predictive components for future asset returns may be expressed in terms of observable variables, namely in terms of consumption, asset holdings and labor income. The framework implies that these variables are cointegrated, and that deviations from this shared trend summarize agents' expectations of future returns on the market portfolio.     

Foreign portfolio equity holdings and capital gains taxation

Using panel data from 23 developed countries over the 2001–2011 period and employing the Arellano-Bover/Blundell-Bond dynamic panel estimation technique, this paper shows that the source country capital gains tax has a negative and statistically significant impact on foreign portfolio equity holdings. On average, a 1 percentage point increase in capital gains tax rate leads to 0.018% decrease in foreign equity holdings. The negative relationship between the capital gains tax and foreign equity holdings is found to be robust to alternative measures of the source country capital gains tax, inclusion of the dividend imputation tax rate, foreign dividend tax withheld rate, dividend tax credit and other control variables (the source and host country financial wealth, trade, exchange rate volatility, foreign listing and institutional quality). We find that a 1% increase in financial wealth of the source (host) country leads to, on average, a 0.428% (0.427%) increase in foreign equity holdings. An improvement in institutional quality has a positive effect on foreign equity holdings but an increase in the exchange rate volatility has the opposite effect.     

The information content of cash dividend announcements in a unique environment

Due to its distinctive institutional background, Oman offers a valuable opportunity to examine stock price reactions to dividend announcements. In Oman, (1) there are no taxes on dividends and capital gains, (2) there is a high concentration of share ownership, (3) there is low corporate transparency, and (4) firms frequently change their dividends. Our results show that announcements of dividend increases are associated with increased stock prices, while announcements of dividend decreases cause decreases in stock prices. Firms that do not change their dividends experience insignificant negative returns. These results contradict tax-based signaling models, which argue that higher taxes on dividends relative to capital gains are a necessary condition for dividends to be informative.     

Market Valuation of Tax-Timing Options: Evidence from Capital Gains Distributions

We examine a distribution that is taxed as a capital gain rather than as a dividend. Since the distribution induces a realized capital gain while the price change is an unrealized gain, ex‐day return behavior provides evidence of the value of tax‐timing capital gains. We show that investors are compensated 7¢ in unrealized gains for each dollar of realized capital gains, that is, $1 of realized capital gains is equivalent to 93¢ of unrealized gains. An investor with a tax rate on realized gains of 15% has an effective tax rate on unrealized capital gains of 8.6%.     

Wealth redistributions or changes in firm value: An analysis of returns to bondholders and stockholders around dividend announcements

Past studies indicate that stock prices are affected by announcements of unexpected dividend changes, i.e., unexpectedly large dividends are associated with positive stock price response. Two explanations of this empirical regularity, ‘the information content hypothesis’ and the ‘wealth redistribution hypothesis’, imply different bond price behavior around dividend announcements. The information content hypothesis predicts a positive bond price response to unexpectedly large dividends, while the wealth redistribution hypothesis predicts the opposite. This paper distinguishes between the relative importance of the two hypotheses by empirically investigating bond price behavior around dividend announcements. The evidence presented is consistent with the information content hypothesis. However, the gains associated with positive information are captured by the stockholders, while the losses are shared with the bondholders.     

Direct evidence of dividend tax clienteles

The paper is the first to evaluate the dividend tax clientele hypothesis using a data set of all domestic stock portfolios in the market. We find that investment funds that face a higher effective tax rate on dividend income than on capital gains tilt their portfolios away from dividend-paying stocks. These investors consequently earn a dividend yield that is about 35 basis points lower than that of investors who are tax neutral between dividends and capital gains (pension funds, unit-linked insurance, life insurance). Consistent with tax rules and charter provisions, we also find that private corporations prefer growth stocks, that foundations exhibit strong dividend preferences, and that partnerships rarely hold stocks portfolios.

Dividend and capital gains taxation under incomplete markets

Motivated by the Jobs and Growth Tax Relief Reconciliation Act (JGTRRA) of 2003, the effects of capital income tax cuts are investigated in an economy with heterogeneous households and a representative, mature firm. Dividend tax cuts, contrary to capital gains tax cuts, lead to a decrease in investment and capital. This is because they increase the market value of existing capital and households require a higher return to hold this additional wealth. In line with empirical evidence, the model predicts substantial increases in dividends and stock prices. Overall, the tax cuts lead to a welfare reduction equivalent to a consumption drop of 0.5%.     

Capital Gains, Dividend Yields, and Expected Inflation

One explanation for the negative relationship between short-horizon stock returns and inflation is that inflation proxies (inversely) for expected future real output. In this paper, I examine the possibility that inflation also proxies for variation in real price/dividend ratios (excess returns). I show that when the covariance between real price/dividend ratios and inflation is nonzero, the relationship between returns and expected inflation differs for the two components of returns: dividend yields and capital gains returns. My empirical evidence demonstrates that dividend yields and capital gains are related differently to expected inflation in U.S. and foreign markets.     

Taxes,dividend yields and returns in the UK equity market

The higher rate of taxation on dividend income relative to capital gains has been offered as an explanation for the positive relation between stock returns and dividend yields among US firms. In the UK the relative tax rates are the reverse of those in the US. Thus, UK data provides an independent test of the tax-based approach to explaining the relation between stock returns and dividend yields. We find that high yielding stocks earn positive risk adjusted returns, whereas low yielding stocks earn negative risk adjusted returns. We also detect evidence of non-linearity in the performance of zero-dividend stocks. Controlling for firm size, seasonality and market risk we find a significant positive relation between dividend yields and returns. We conclude that the evidence is inconsistent with a tax-based explanation.     

Lost in translation: Delayed ex-dividend price adjustments of Hong Kong ADRs

Previous research documents that Hong Kong stocks have a full ex-dividend price adjustment consistent with dividends and capital gains being tax free. We examine ex-dividend price behavior of Hong Kong ADRs to assess the impact of differing tax environments in US and Hong Kong. These ADRs typically go ex-dividend before their underlying stock. They experience significant abnormal returns of 1.16% on their ex-day; the average ex-day price drop is only 30% of the dividend. However, ADR prices drop when the underlying stock goes ex-dividend subsequently. The cumulative ADR price drop is equal to the dividend. Thus, the ADR ex-dividend adjustment resembles that of the underlying stock, consistent with home country tax laws governing ADR price behavior. Neither liquidity nor transaction costs can explain the anomalous delayed ex-dividend adjustment of ADRs.     

Corporate social responsibility and the wealth gains from dividend increases

This study examines whether corporate social responsibility (CSR) influences the stock price response to dividend increase announcements and changes in subsequent operating performance. We find that dividend increasing firms with lower CSR scores elicit higher abnormal announcement returns and greater improvements in industry‐adjusted operating performance. These findings support the argument in the literature that socially responsible firms are more transparent and commit to higher ethical standards than other firms, suggesting that they suffer fewer agency and informational problems (Kim, Park, & Wier, 2012). Consequently, larger dividend payouts reduce agency costs in firms with lower CSR commitments, thereby generating higher wealth gains for shareholders.     

Tax clientele effects of dividends under intertemporal consumption choices

Corporate investors putatively seek high dividends because marginal tax rates on dividends are lower than those on capital gains. However, a lower tax “rate” does not necessarily mean that a higher dividend is desirable. Taking the intertemporal consumption choices given, corporate investors are expected to prefer “time-preference-fitted dividends” if tax rates remain constant over time; otherwise they confront a larger “amount” of tax obligation. If dividend shortfalls exist, they must realize capital gains and thereby suffer unfavorable tax treatment, whereas excessive payments cause intertemporal double taxation on reinvested dividends. Tax-saving problems should be linked with intertemporal consumption choices.     

Dividend yields and stock returns: Implications of abnormal January returns

This study examines the empirical relation between stock returns and (long-run) dividend yields. The findings show that much of the phenomenon is due to a nonlinear relation between dividend yields and returns in January. Regression coefficients on dividend yields, which some models predict should be non-zero due to differential taxation of dividends and capital gains, exhibit a significant January seasonal, even when controlling for size. This finding is significant since there are no provisions in the after-tax asset pricing models that predict the tax differential is more important in January than in other months.     

The Effect of Dividend Changes on Stock and Bond Prices

This study examines stock and bond price reactions to dividend changes. The positive stock market response to dividend increases has several potential explanations, two of the more commonly discussed being information content and wealth redistribution between stockholders and bondholders. The evidence presented supports the wealth redistribution hypothesis but does not rule out the information content hypothesis. Typically we find that the bond price reaction to announcements of large dividend changes is opposite to the stock price reaction. Our results differ from those of Handjinicolaou and Kalay.     

FURTHER EVIDENCE ON DIVIDEND YIELDS AND THE EX-DIVIDEND DAY STOCK PRICE EFFECT

Ex-dividend day stock price behavior supports a tax clientele effect. This effect is still found after the Tax Reform Act of 1986. Results reflect an effective tax advantage for capital gains taxes payable at realization, versus dividend taxes due quarterly. Evidence also supports short-term trader participation in the ex-day phenomenon when the difference between dividend income and the ex-dividend-day price decrease exceeds transactions costs to trade. Results contradict prior research where a tax clientele effect is not found, but align with this prior research when including a small number of contaminated observations.     

Unintended Consequences of Changing Accounting Standards: The Case of Fair Value Accounting and Mandatory Dividends

A growing body of literature investigates the interaction of changes in accounting standards with institutions such as investor protection laws and corporate governance mechanisms. We examine the unintended consequences of fair value accounting in determining mandated preferred dividends. We study the case of Russian energy conglomerate UES, which had a good corporate governance track record and a consistent dividend history. Following its adoption of fair value accounting, UES reported the highest quarterly profit in world corporate history, but it subsequently omitted dividends for all its shareholders. The case analysis suggests that the transitory nature of fair value adjustments and the interaction with the investment policy were important considerations in justifying the dividend omission. The reduction in preferred dividends was not offset by any capital gains, and led to a wealth transfer from preferred to ordinary shareholders. Thus, requiring the use of fair value accounting when determining the dividend distribution base can lead to unintended consequences and increase agency costs for minority shareholders.     

Dividend Changes and Security Prices

This paper analyzes the effect of unexpected dividend changes on the values of common stock, preferred stock, and bonds. Two potential effects are identified: a wealth transfer effect and a signalling effect. Previous studies have shown that positive (negative) dividend change announcements produce positive (negative) common stock price changes. Whereas these findings have been attributed to the signalling aspect of dividends, they are also consistent with the wealth transfer hypothesis. Based on the announcement day returns of common and preferred stock and bond holders, it is demonstrated that the primary factor influencing security returns in response to dividend changes is market signalling. A wealth transfer effect is not necessarily ruled out, but if it exists it is dominated by the signalling effect.     

Canada's Dual Class Shares: Further Evidence on the Market Value of Cash Dividends

The Canada Income Tax Act of 1971 permitted Canadian corporations to create two classes of equity, one paying ordinary cash income and the other paying capital gains income. Cash-paying shares have often sold at a premium. Empirical results indicate that the premium is largely explained by the relative value of the dividends paid and by costs imposed on investors by stock dividend payment and share conversion procedures. Premiums for a few firms also reflect the relative liquidity of the two classes of shares. No evidence exists that investors prefer cash income to equal amounts of capital gains.
