Corporate tax avoidance and stock price crash risk: Firm-level analysis

Using a large sample of U.S. firms for the period 1995–2008, we provide strong and robust evidence that corporate tax avoidance is positively associated with firm-specific stock price crash risk. This finding is consistent with the following view: Tax avoidance facilitates managerial rent extraction and bad news hoarding activities for extended periods by providing tools, masks, and justifications for these opportunistic behaviors. The hoarding and accumulation of bad news for extended periods lead to stock price crashes when the accumulated hidden bad news crosses a tipping point, and thus comes out all at once. Moreover, we show that the positive relation between tax avoidance and crash risk is attenuated when firms have strong external monitoring mechanisms such as high institutional ownership, high analyst coverage, and greater takeover threat from corporate control markets.     

The Impact of Information Processing Costs on Firm Disclosure Choice: Evidence from the XBRL Mandate

This paper examines the effect of market participants’ information processing costs on firms’ disclosure choice. Using the recent eXtensible Business Reporting Language (XBRL) regulation, I find that firms increase their quantitative footnote disclosures upon implementation of XBRL detailed tagging requirements designed to reduce information users’ processing costs. These results hold in a difference‐in‐difference design using matched nonadopting firms as controls, as well as two additional identification strategies. Examination of the disclosure increase by footnote type suggests that both regulatory and nonregulatory market participants play a role in monitoring firm disclosures. Overall, these findings suggest that the processing costs of market participants can be significant enough to impact firms’ disclosure decisions.     

Does online interaction between firms and investors reduce stock price crash risk?

This paper examines how online interaction between firm management and investors impacts stock price crash risk. Based on the previous literature, we postulate that online interaction constrains crash risk via two channels, i.e., deterring bad news hoarding activities of managers and decreasing differences of opinion among investors. Relying on the launch of Hudongyi (the first official investor relations management platform in the world) for identification, we demonstrate that online firm-investor interaction significantly reduces future stock price crash risk and that these two channels can both explain this effect. Overall, our findings highlight the important role of online interaction in risk management.     

Economic policy uncertainty and stock price crash risk

We examine the impact of economic policy uncertainty (EPU) on firm-specific crash risk. Based on a large sample of Chinese listed firms over the period from 2000 to 2017, we provide empirical evidence that firms are more likely to experience stock price crashes when EPU increases. Cross-sectionally analysis further reveals that the impact of EPU on stock price crash risk is stronger for firms whose returns are more sensitive to EPU. More specifically, young stocks, small stocks, high volatility stocks, and growth stocks, which have higher valuation uncertainty per se, are more sensitive to EPU and are more affected by EPU in terms of crash risk. We further show that EPU is significantly and positively associated with aggregated stock price crash risk at the market level.     

Family firms and crash risk: Alignment and entrenchment effects

Stock price crash risk could be lower in family firms because the controlling family investors have a longer-term interest, hold greater decision rights and are better informed than investors in diffusely owned firms (alignment effect). However, the agency costs between family and nonfamily investors (entrenchment effect) could affect crash risk in two opposing ways. Non-controlling investor skepticism about insider entrenchment limits overvaluation and reduces the crash risk. In contrast, entrenched insiders could hide bad news to exploit private benefits, which could increase the crash risk. We show that family firms exhibit a lower crash risk than similar nonfamily firms after controlling for lower overvaluation, which is consistent with the better alignment effect. Moreover, we show that better governance further reduces the crash risk, which indicates that the substitutive relationship between strong governance and family ownership shown in countries with low investor protection rights does not carry over to the U.S. where investor protection rights are strong.     

Board diversity and stock price crash risk

We show how board diversity influences stock price crash risk. By classifying board diversity into relation-oriented diversity (gender and age) and task-oriented diversity (tenure and education), we find that greater diversity on board can lower the risk of future stock crash. Additional analyses show that the effect of board diversity on future crash risk is stronger for firms with high information opacity and low institutional ownership. Overall, our findings provide new insights and suggest for more diverse boards to improve corporate governance practices.     

Seasoned equity offerings: Quality of accounting information and expected flotation costs

Flotation costs represent a significant loss of capital to firms and are positively related to information asymmetry between managers and outside investors. We measure a firm's information asymmetry by its accounting information quality based on two extensions of the Dechow and Dichev [2002. The quality of accruals and earnings: the role of accrual estimation errors. Accounting Review 77, 35–59] earnings accruals model, which is a more direct approach to assessing the information available to outside investors than the more commonly used proxies. Our main hypothesis is that poor accounting information quality raises uncertainty about a firm's financial condition for outside investors, though not necessarily for insiders. This accounting effect lowers demand for a firm's new equity, thereby raising underwriting costs and risk. Using a large sample of seasoned equity offerings (SEOs), we show that poor accounting information quality is associated with higher flotation costs in terms of larger underwriting fees, larger negative SEO announcement effects, and a higher probability of SEO withdrawals. These results are robust to joint determination of offer size and flotation cost components and to adjustments for sample selection bias.     

Major government customers and stock price crash risk

This paper studies whether government’s participation in product market, as a customer, affects supplier firms’ stock price crash risk. Using a sample of U.S. firms from 1980 to 2015, we find robust evidence that the presence of major government customers is associated with a lower level of stock price crash risk for supplier firms. Further, we show that government customers can lower suppliers’ crash risk by imposing monitoring activities on suppliers and/or reducing suppliers’ operational risk, leading to a reduction in supplier managers’ bad news hoarding behavior. Overall, our results indicate that government spending, as an important public policy, can significantly affect shareholders’ value by mitigating stock price crash risk.     

Liquidity risk and expected corporate bond returns

This paper studies the pricing of liquidity risk in the cross section of corporate bonds for the period from January 1994 to March 2009. The average return on bonds with high sensitivities to aggregate liquidity exceeds that for bonds with low sensitivities by about 4% annually. The positive relation between expected corporate bond returns and liquidity beta is robust to the effects of default and term betas, liquidity level, and other bond characteristics, as well as to different model specifications, test methodologies, and a variety of liquidity measures. The results suggest that liquidity risk is an important determinant of expected corporate bond returns.     

Extreme downside risk and expected stock returns

We propose a measure for extreme downside risk (EDR) to investigate whether bearing such a risk is rewarded by higher expected stock returns. By constructing an EDR proxy with the left tail index in the classical generalized extreme value distribution, we document a significantly positive EDR premium in cross-section of stock returns even after controlling for market, size, value, momentum, and liquidity effects. The EDR premium is more prominent among glamor stocks and when high market returns are expected. High-EDR stocks are generally characterized by high idiosyncratic risk, large downside beta, lower coskewness and cokurtosis, and high bankruptcy risk. The EDR premium persists after these characteristics are controlled for. Although Value at Risk (VaR) plays a significant role in explaining the EDR premium, it cannot completely subsume the EDR effect.     

Value relevance of conservative and non-conservative accounting information

The present paper examines effects of reporting conservatism on the value relevance of accounting earnings of a sample of Greek firms over the period from 1989 to 2003. The results of the paper indicate that conservatism is a salient feature of the Greek Accounting System. Moreover, the results depict that the level of conservatism has increased after the market crisis of 1999, potentially as a result of the additional regulation, imposed by the market authorities during the post-crisis period. Finally, the results show that there is a non-linear association between conservative reporting and value relevance of earnings. In particular, value relevance increases when moving from low-conservative firms to medium-conservative firms and decreases when moving further to high-conservative firms. Overall, the results of the paper lend empirical support to the theoretical underpinnings of Watts (2003a) who, on the one hand, report a number of arguments in favor of conservatism but, on the other hand, questions the practice of excessive conservative reporting as being a potential cause of the distortion of the earnings-returns relation.     

Distress risk premia in expected stock and bond returns

Prior studies find that shareholders’ strategic actions over debtholders are significant for stock prices but not for bond prices. I find that for firms with private and public debt, strategic default has no significant effect on distress risk premia in expected stock or bond returns, suggesting that the dispersion of bondholders greatly weakens the shareholder advantage effect. The shareholder advantage effect on stock prices is only significant for firms with only private debt and to some degree affected by the dispersion of stockholders and complexity in capital structure. Overall, renegotiation friction helps explain the cross-sectional implications of strategic default for stock and bond prices.     

Institutional cross-ownership and stock price crash risk

Using manually collected data of Chinese listed firms during the period 2007–2018, we provide strong and robust evidence that institutional cross-ownership is negatively associated with firm-specific stock price crash risk. Building on China’s institutional settings, we document that the negative relation is more pronounced for firms located in provinces with higher political uncertainty, or state-owned enterprises. This paper also conducts several mechanisms analyses and has confirmed three potential influencing mechanisms, such as information advantage, governance improvement and anticompetitive incentives, in explaining the effect of institutional cross-ownership on stock price crash risk. Overall, this paper develops a new perspective to investigate the ways to alleviate stock price crash risk in emerging markets.     

Board directors with foreign experience and stock price crash risk: Evidence from China

This study examines the impact of board directors with foreign experience (BDFEs) on stock price crash risk. We find that BDFEs help reduce crash risk. This association is robust to a series of robustness checks, including a firm fixed effects model, controlling for possibly omitted variables, and instrumental variable estimations. Moreover, we find that the negative association between BDFEs and crash risk is more pronounced for firms with more agency problems, weaker corporate governance, and less overall transparency. Our findings suggest that the characteristics of board directors matter in determining stock price crash risk.     

The intertemporal relation between expected returns and risk

This paper explores the time-series relation between expected returns and risk for a large cross section of industry and size/book-to-market portfolios. I use a bivariate generalized autoregressive conditional heteroskedasticity (GARCH) model to estimate a portfolio's conditional covariance with the market and then test whether the conditional covariance predicts time–variation in the portfolio's expected return. Restricting the slope to be the same across assets, the risk-return coefficient is highly significant with a risk–aversion coefficient (slope) between one and five. The results are robust to different portfolio formations, alternative GARCH specifications, additional state variables, and small sample biases. When conditional covariances are replaced by conditional betas, the risk premium on beta is estimated to be in the range of 3% to 5% per annum and is statistically significant.     

Stock performance and the mispricing of accruals

I investigate the relationship between contemporaneous stock-price performance and the persistence of accrued earnings, and its impact on the accrual anomaly. I find that, in a fiscal year, accrued earnings for stocks that have performed poorly are less persistent in predicting future earnings than accrued earnings for stocks that have performed moderately. I further find that a hedge-strategy based on accruals earns greater abnormal returns following bad-news years. The results are consistent with conservative accounting causing accrued earnings to be even less persistent in bad-news years and investors failing to efficiently price this differential in persistence.     

Macro to micro: Country exposures,firm fundamentals and stock returns

We outline a systematic approach to incorporate macroeconomic information into firm level forecasting from the perspective of an equity investor. Using a global sample of 198,315 firm-years over the 1998–2010 time period, we find that combining firm level exposures to countries (via geographic segment data) with forecasts of country level performance, is able to generate superior forecasts for firm fundamentals. This result is particularly evident for purely domestic firms. We further find that this forecasting benefit is associated with future excess stock returns. These relations are stronger after periods of higher dispersion in expected country level performance.     

The relationship between risk and expected return in Europe

We employ MIDAS (mixed data sampling) to study the risk–expected return trade-off in several European stock indices. Using MIDAS, we report that in most indices there is a significant positive relationship between risk and expected return. This strongly contrasts with the result we obtain when we employ both symmetric and asymmetric GARCH models for conditional variance. We also find that asymmetric specifications of the variance process within the MIDAS framework improve the relationship between risk and expected return. As an additional application, we analyze the extent to which European stock markets are integrated, which is a particularly relevant issue, especially following the launch of the Euro in January 1999. Finally, we propose a bivariate MIDAS specification to test the pricing significance of the hedging component within an intertemporal risk–return trade-off with multiple European market indices.
