Optimal tax-timing and asset allocation when tax rebates on capital losses are limited

This article studies the portfolio problem with realization-based capital gain taxation when limited amounts of losses qualify for tax rebate payments, as is the case under current US tax law. When the tax rate applicable to realized losses exceeds that on realized capital gains, it can be optimal to realize capital gains immediately and pay capital gain taxes to regain the option to use potential future losses against a higher tax rate. This incentive adds an entirely new and as yet unstudied dimension to the portfolio problem. It causes risk averse investors to hold more equity and attain higher welfare levels than is the case when trading under a tax system that seeks to collect the same amount of taxes, but does not allow for tax rebate payments. This is because the benefit to these investors from having their losses subsidized is greater than the suffering from having profits taxed at a higher rate.     

Mutual funds' capital gains lock-in and earnings management

Capital gains taxation creates a lock-in effect, increasing investors' incentives to monitor and decreasing portfolio firms' incentives to cater to short-term investors. We show a negative relation between lock-in and portfolio firms' earnings management, and this relation is stronger for capital gains held by tax-sensitive investors. Further, the relation between lock-in and earnings management is stronger when the capital gains tax rate is higher. We show that locked-in funds vote against management and against audit committee members' reappointment following earnings management. Locked-in funds are less likely to exit a position following disappointing earnings announcements, reducing firms' incentive to manage earnings.     

Tax Reform and Ex-Dividend Day Behavior

This paper investigates the effect of a major Canadian tax reform on the ex-dividend day behavior of companies on the Toronto Stock Exchange. The results are inconsistent with the hypothesis that price changes on ex-dividend days reflect the relative taxation of dividends and capital gains for the “representative” investor, but are consistent with the hypothesis that ex-dividend day price behavior reflects short-term trading activities.

Portfolio Rebalancing and the Turn-of-the-Year Effect

This paper finds that, for the 1935–1986 period, the market's risk-return relation does not have a January seasonal. The findings differ from those of other studies due to the use of value-weighted, rather than equally weighted, portfolios. Inferences are sensitive to the weighting procedure because of the small-firm return patterns in January. In particular, even in those Januaries for which the market return is negative, small-firm returns are positive, and they are more positive the higher is beta. This is consistent with the portfolio rebalancing explanation of the turn-of-the-year effect.     

Leveraged superannuation

Rules governing superannuation investments are made with respect to investment‐specific risks, rather than overall portfolio risks. In particular, legislation prohibits borrowing except in specific circumstances and on a non‐recourse basis. We model the distribution of leveraged portfolio outcomes for a representative investor, accounting for their age‐earnings profile, differing taxation of dividends, capital gains and franking credits, and the volatility of equity returns and interest rates. With explicit portfolio modelling, there is no need to categorize specific investments as ‘too risky’ on a stand‐alone basis. We show that leverage is likely to enhance retirement outcomes for investors with low risk aversion.     

Investor induced contagion during the banking and European sovereign debt crisis of 2007–2012: Wealth effect or portfolio rebalancing?

This study investigates the way a crisis spreads within a country and across borders by testing the investor induced contagion hypothesis through the liquidity channel on stock-bond relationships of the US and five European countries before and during the global banking and European sovereign debt crisis of 2007–2012. We provide evidence consistent with the wealth effect as a source of contagion for the majority of countries. Nevertheless, we uncover evidence of investor induced contagion sourced by the portfolio rebalancing effect for correlations involving Spanish and Italian bonds during the debt crisis. Further, we find that tight (narrow) credit spreads reduce (magnify) the wealth and portfolio rebalancing effects, which are offset by the opposite effects of risk aversion amongst investors, a dynamic that is not restricted to crisis periods.     

An Alternative View on Determinants of the Effective Tax Rate: Evidence from Chinese Listed Companies

This article proposes a new model for determining the effective tax rate (ETR), which incorporates the accounting-tax conformity theory and identifies ETR determinant variables to fit the Chinese taxation context. The results show that the ETR is statistically significantly associated with preferential tax rates, investment gains, nonoperating expenses, and provisions for impaired assets. The accounting-tax difference ETR determinant variables provide more consistent results than previous typical ETR determinants, such as size, return on assets, leverage, and capital intensity.     

International tax arbitrage,financial parity conditions and preferential capital gains taxation

Using a finite-horizon general equilibrium model with uncertainty and money, we characterize situations where tax arbitrage opportunities may arise for international portfolio investors in an economy with heterogeneous capital income taxation when interest income and capital gains/losses are taxed differentially for some agents. We derive tax-modified uncovered interest parity conditions, Fisher conditions and forward prices similar to the no-tax ones, but augmented by tax-induced ‘risk-premium’ terms; covered interest parity and Fisher conditions remain unaffected by the introduction of capital income taxes as we bound tax-based arbitrage without restricting arbitrage per se.     

Optimal stock trading with personal taxes: Implications for prices and the abnormal January returns

The tax law confers upon the investor a timing option - to realize capital losses and defer capital gains. With the tax rate on long term gains and losses being about half the short term rate, the law provides a second timing option - to realize losses short term and gains long term, if at all. Our theory and simulation over the 1962–1977 period establish that taxable investors should realize long term gains in high variance stocks and repurchase stock in order to realize potential future losses short term. Tax trading does not explain the small-firm anomaly but predicts a seasonal pattern in trading volume which maps into a seasonal pattern in stock prices, the January anomaly, only if investors are irrational or ignorant of the price seasonality.     

Effects of Capital Gains Taxation on Life-Cycle Investment and Portfolio Management

We examine the impact of capital income taxation, both accrual forms of taxation and taxation of realized capital gains, on total savings and the demand for corporate financial instruments. We find that investors may hold both debt and equity in the face of effective collection of capital gains taxation even in a flat tax system. We also find that the two taxes will have substantially different effects on saving and consumption behavior, making it unlikely that the tax structure can be summarized by any single equivalent accrual tax rate.     

Macroeconomic Seasonality and the January Effect

Many financial markets researchers have sought an explanation for the role of January in stock returns. Any explanation of this phenomenon that is consistent with rational pricing must specify a source of seasonality in expected returns. The pervasive seasonality in the macroeconomy is an appealing possibility. A multifactor model that links macroeconomic risk to expected return is found to show substantial seasonality in expected returns. This model accounts for the seasonality in average returns, while the capital asset pricing model cannot.     

The tax-loss selling hypothesis,market liquidity,and price pressure around the turn-of-the-year

In this paper, we use intra-day data for all stocks listed on the ISSM and provide new and direct evidence consistent with the tax-loss selling hypothesis. We find that (a) there is abnormal selling pressure prior to the year-end for stocks that have experienced large capital losses in the current and prior years (b) investors delay realizing capital gain by postponing the sale of capital gain stocks until after the new year (c) there is a significant decrease in the average trade size for stocks with large capital losses before the year-end and for stocks with capital gains in the new year, which suggests that individuals, rather than institutional investors, are the major sellers around the year-end (d) the tax-loss selling hypothesis, and not firm size or share price, is the fundamental explanation for abnormal January returns. Further, small or low share priced firms with capital gains do not experience abnormal returns in January. However, conditional on capital losses, small or low share priced firms magnify the turn-of-the-year effect (e) On average, the increase in selling activity adversely affects market liquidity by increasing bid-ask spreads and reducing depths. (f) The tax-loss selling pressure not only causes the price to be at the bid at the year-end, it also temporarily depresses the equilibrium price indicating the short run demand curve is not perfectly elastic (g) the year-end buying activity suggests that large investors buy capital loss stocks prior to the year-end to take advantage of the temporarily depressed price and capital gain stocks after the new year to reinvest the proceeds of the tax-loss selling.     

Direct evidence on the marginal rate of taxation on dividend income

Miller and Scholes (1978) hypothesize that the marginal tax rate on dividend income may be less than the marginal rate of tax on capital gains. Their hypothesis is dependent upon individuals utilizing existing provisions of the Code which serve to reduce the taxation of dividends. In this study, estimates of the marginal and effective rates of tax on dividend income for the year 1979 are presented using the Statistics of Income sample of returns. The average marginal rate of tax on dividend income is estimated to be 40%, while the average effective rate of tax is estimated to be 30%.     

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.     

Capital gains tax and the capital asset pricing model

This paper develops a version of the Capital Asset Pricing Model that views dividend imputation as affecting company tax and assumes differential taxation of capital gains and ordinary income. These taxation issues aside, the model otherwise rests on the standard assumptions including full segmentation of national capital markets. It also treats dividend policy as exogenously determined. Estimates of the cost of equity based on this model are then compared with estimates based on the version of the CAPM typically applied in Australia, which differs only in assuming equality of the tax rates on capital gains and ordinary income. The differences between the estimates can be material. In particular, with a high dividend yield, allowance for differential taxation can result in an increase of two to three percentage points in the estimated cost of equity. The overall result obtained here carries over to a dividend equilibrium, in which firms choose a dividend policy that is optimal relative to the assumed tax structure.     

Infrequent Rebalancing,Return Autocorrelation,and Seasonality

A model of infrequent rebalancing can explain specific predictability patterns in the time series and cross‐section of stock returns. First, infrequent rebalancing produces return autocorrelations that are consistent with empirical evidence from intraday returns and new evidence from daily returns. Autocorrelations can switch sign and become positive at the rebalancing horizon. Second, the cross‐sectional variance in expected returns is larger when more traders rebalance. This effect generates seasonality in the cross‐section of stock returns, which can help explain available empirical evidence.     

Taxation of shareholder capital gains and the choice of payment method in takeovers

From December 1999, shareholders who disposed of shares in Australian takeovers in exchange for scrip could elect to defer capital gains taxation until the disposal of the shares received. We investigate payment method choice by acquiring firms before and after this regulatory change to assess whether target shareholder capital gains tax liabilities became an important factor considered in choosing the form of payment. The results show that, subsequent to the regulatory change, there is a significantly higher probability that equity will be offered as consideration where target shareholder capital gains are greater. This finding confirms the importance of shareholder level taxation in explaining corporate acquisition structure and adds to previous European and US evidence on factors associated with payment method choice in takeovers.     

Stock Market Returns and Consumption

This paper employs Swedish data on households' stock holdings to investigate how consumption responds to changes in stock market returns. We instrument the actual capital gains and dividend payments with past portfolio weights. Unrealized capital gains lead to a marginal propensity to consume of 23% for the bottom 50% of the wealth distribution and about 3% for the top 30% of the wealth distribution. Household consumption is significantly more responsive to dividend payouts across all parts of the wealth distribution. Our findings are consistent with households treating capital gains and dividends as separate sources of income.     

The risk adjusted uncovered equity parity

This paper explores the risk adjusted uncovered equity parity model to investigate a degree of market integration for four Asian emerging markets relative to the U.S., Japan and the U.K. from January 1994 to July 2008. The uncovered equity parity is revised to take into account of market risk in a framework of a portfolio rebalancing model. Evidence was found to strongly support our hypotheses; Market risk is significant in international capital flows between the Asian emerging markets and the developed economies, and it can help explain the failure of a traditional uncovered equity (or interest) parity model. The relationship between returns and an appreciation of the exchange rate are divided between the Asian emerging markets and the developed economies, depending on the direction of capital flows.
