Corporate Environmental Litigations: Peer Effects and Its Relationship to Firm Environmental, Social and Governance (ESG) Performance
The dissertation analyzes three issues related to corporate environmental performance. In the first essay, I analyze the stock price reactions of the defendant firms and their peer firms to environmental lawsuits. Empirical evidence finds that the defendant and their peer firms experience negative and significant cumulative abnormal returns to the announcement of environmental lawsuits. Additionally, cross-sectional analyses find certain firm characteristics, such as profitability, growth opportunities and leverage can influence the market reaction. Furthermore, if the plaintiffs are government agencies or corporations instead of individual citizens, the defendant and peer firms experience higher negative market reactions. The second essay examines if a firm's environmental, social, and governance (ESG) performance can moderate the negative market response to environmental lawsuits. The results are mixed. The overall sample of the defendant and their peer firms show that ESG performance is not a significant factor in mitigating the negative market response. However, an interesting finding shows, for defendant and peer firms in the environmentally sensitive industries, better ESG ratings help reduce the adverse market reactions. The final essay investigates whether the defendant and peer firms improve their ESG performance in the next two years following the lawsuits. The results indicates that firms generally experience a drop in their ESG ratings in the year the lawsuits are filed. However, post-lawsuit filing years, there is a general trend for the defendant and peer firms in the environmentally sensitive industries to improve their environmental performance.
Determinants of Portfolio Manager Ownership
This paper investigates the determinants of mutual fund portfolio manager ownership and its association with fund performance. Using hand-collected data of 1,420 U.S. equity funds from 32 fund families, we find that variations in fund manager holdings are broadly consistent with optimal contracting theory instead of the result of managers' personal investment consideration. Portfolio manager ownership is positively and significantly correlated with variables that proxy for intensity of agency conflicts. Specifically, portfolio managers hold more mutual fund shares when the size of concurrently managed hedge fund increases and when the advisor is affiliated to the bank. In addition, fund managers invest more in funds with primary investment in growth stock, non-index funds, and solo-managed funds. Regarding to the alternative governance mechanism, higher threat of dismissal for outsourced funds, stronger monitoring from institutional investors, and long-term performance based bonus work as substitutes of fund manager ownership while director ownership works as a compliment. Finally, we find little evidence supporting the notion that funds with higher portfolio manager ownership perform better.
An Empirical Investigation into the Value of Credit Lines
Access to adequate liquidity to finance future investments is an essential element of financial management. The two main questions that this dissertation attempts to answer are (i) what is the net valuation effect of LoC? and (ii) if LoC create value, what are the sources of this value? To answer these questions, I constructed a sample of 85,232 firm-years spanning from 1993 to 2016, with credit line data obtained from Capital IQ and Bloomberg. I investigated the valuation effects of LoC with a methodology extensively used in the analysis of the valuation implications of cash. I used this methodology because cash and LoC are two alternatives to manage liquidity and estimated the changes in shareholders' value associated with changes in existing LoC undrawn balances and on new LoC agreements. The results from this analysis demonstrates a positive association between increases in LoC capacity and shareholder's value. These findings are also obtained in univariate and event study analyses. The results also suggest that LoC create more value for firms that are rich in cash, indicating the LoC and cash are complementary liquidity management tools. I then focused on the sources of the value created by credit lines. I examined whether information asymmetry plays a role in LoC valuation by analyzing the association between firm value and LoC for firms with high- and low-information asymmetric. I also studied whether LoCs reduce agency problems by comparing firm value and LoC capacity in both poorly and well-governed firms. Furthermore, I examined whether firms benefit from an increase in financial flexibility provided by access to credit lines. I found results consistent with LoC being more valuable for firms with higher levels of informational asymmetries. The analysis also suggests that LoCs with longer maturity create more value than those with shorter maturity. Surprisingly, I find limited …
Enterprise Risk Management and Firm Operations: Evidence from Inventory Management
Enterprise Risk Management (ERM) is a program that manages all firm risks in an integrated framework to control and coordinate offsetting risks. In this study, I provide the first archival evidence on how ERM affects firms' day-to-day, routine operations. Using hand-collected ERM adoption data and inventory information, I examine whether firms with an ERM program experience an improvement in their inventory management. My findings suggest that ERM adoption is associated with greater inventory turnover ratios and lower inventory impairments. These results are robust to a range of models in addressing endogeneity concerns. Additionally, I find that ERM's effect on inventory management is stronger among firms with greater financial distress, with less investments in innovation, or with higher information asymmetries, and when firms' ERM program grows more mature. My study documents ERM's real economic benefits to firms' operations and highlights how ERM contributes to operating performance.
How is the Volatility Priced by the Stock Market?
Traditional portfolio theory suggests that, in equilibrium, only the market risk is priced in the cross-section of expected stock returns. However, if the market is not perfect and investors are constantly changing investing behaviors based on their perceptions about future market outlook, then non-traditional risk factors could potentially provide significant power of describing the expected stock returns. This dissertation has two essays on the pricing of volatility, in which the market is not assumed to be frictionless or perfect. Essay 1 focuses on the pricing of individual volatility in penny stocks. Empirical results show that individual volatility plays an important role in describing the average cross-sectional returns of penny stocks. Resorting to the rolling portfolio approach, evidences indicate that portfolios consisting of penny stocks with high individual volatilities, on average, earned much higher returns than portfolios consisting of penny stocks with low individual volatilities. This effect is statistically significant when multiple factors are controlled simultaneously. Essay 2 focuses on the pricing of the market volatility among individual stocks. Following the rolling portfolio method, Essay 2 constructs portfolios that consist of individual stocks with various market volatility exposures. Traditional risk factors such as market beta, size, book-to-market, and momentum are controlled respectively to obtain more detailed analyses. Empirical results yield a negative pricing of the market volatility and it is more prominent in stocks that have high market beta, small size, and high book-to-market.
Impact of Market State on Momentum Portfolio Risk and Performance: A Risk-Based Explanation
The momentum puzzle, i.e., stocks that have performed better in the past tend to perform better in the future, has been a constant challenge to classic finance theory. Prior research has failed to provide valid risk-based explanations because winner portfolios do not exhibit higher risk characteristics. Without a convincing risk explanation, the persistence of momentum profit is a violation of the efficient market hypothesis. Today, the momentum puzzle remains one of the very few major anomalies that cannot be explained by Fama-French factor models. I find prior empirical efforts to measure momentum profits and its sources are contaminated by the state of the market during both formation and holding periods. By looking into different market states, classified by both traditional and non-traditional bull and bear market definition, I find the key to at least partially solve the momentum mystery. Momentum stocks are riskier when formed in bull market, and momentum profit is much higher in continuation of market than reverses of market condition, lending empirical support to a risk-based explanation. My definition of market states is essentially based on the risk premium of major risk factors. When market risk is considered a risk factor, if realized market risk premium is positive, it is a bull market; when size is considered a proxy for risk factor, if SMB (small minus big risk premium) is positive, it is a bull market; when valuation (book-to-market) ratio is a proxy for risk factor, if HML (High-minus-Low risk premium) is positive, it is a bull market. This paper also explores simulations using models based on the positive relationship between risk and return. The simulation result confirms that at least part of the momentum profit can be explained by risk.
The Informational Effects of Non-Deal Roadshows
Non-deal roadshows (NDR) are privately held one-on-one meetings between the buy-side of financial institutions and firm management. Using a novel dataset of these meetings, I examine the effects that NDR meetings have on the outcomes of two important corporate events: seasoned equity offerings (SEOs) and mergers and acquisitions (M&As). I also study the potential implications of the information content in NDRs on the behavior of stock returns following earnings announcements, which has been the subject of much academic work. I structure the dissertation in three essays. In the first essay, I examine the relationship between NDR activity and the underpricing of SEOs. I find that NDRs are associated with lower SEO underpricing. This association is stronger for firms with infrequent NDR activity, for smaller firms, and for firms with higher analysts' forecast errors. These findings suggest that NDRs reduce the level of asymmetric information between firms and investors, which results in a lower cost of raising equity. In Essay 2, I investigate whether the occurrence of NDR meetings affects post-earnings-announcement drift (PEAD). I find that PEAD declines after NDR activity when the most recent NDR meeting occurs within one month before the earnings announcement. This decline is most pronounced among smaller firms, firms with high idiosyncratic volatility, and firms with Friday earnings announcements. These findings suggest that NDRs are mechanisms to convey earnings-specific information about forthcoming earnings. In the third essay I explore the relationship between NDRs, the medium of exchange used in M&As and the value created by this important corporate event. I show that NDR activity is important to understand the cross-sectional variation of the excess returns around M&As, and the bid premium. NDRs are also relevant to understand the medium of exchange. This relevance of NDR is more pronounced when the firms involved have higher levels of …
Three Essays on Size Premium Puzzle
Size premium puzzle, also known as the size effect, is one of the most studied anomalies in asset pricing literature. It refers to the observation that, on average, smaller firms have higher risk-adjusted returns than larger firms over a long period of time. While many studies have debated the existence of the size effect, the question of why it exists has become a subject of heated debate. Thus, this dissertation aims to examine if previously overlooked factors can, at least partially, explain the size effect. Essay 1 examines if merger and acquisition activity can explain a part of the size effect. I find that merger and acquisition activity explain a part of the size effect. The size effect is found to be stronger during merger waves but is not consistent across industries. Further, the size effect tends to be stronger when acquisition activity is concentrated among smaller firms. Essay 2 investigates if expectational errors explain the higher return of small firms. Several empirical studies show that stocks that investors underestimate yield higher returns. However, I do not find support for the underestimation explanation in explaining the higher returns of small firms. Instead, I find that investors are overly optimistic about the growth of small firms. In essay 3, I examine if the size effect can be explained by perceived risk. Using the implied cost of capital (ICC) as a measure of perceived risk, I find that small firms are perceived to be riskier by the market, and the perceived risk explains the size effect.
The Two Sides of Value Premium: Decomposing the Value Premium
Scholars and investors have studied the value premium for several decades. However, the debate over whether risk factors or biased market participants cause the value premium has never been settled. The risk explanation argues that value firms are fundamentally riskier than growth firms. At the same time, the behavioral explanation argues that biased market participants systematically misprice value and growth stocks. In this paper, I use the implied cost of equity capital to capture all risks that investors demand a premium and sort stocks into risk quantiles. The implied cost of equity capital is estimated using models proposed by Gebhardt et al., Claus and Thomas, Ohlson and Juettner-Nauroth, and Easton. I find that value stocks have higher implied cost of equity capital and lower forecasted earnings growth while growth stocks have lower implied cost of equity capital and higher forecasted earnings growth. More importantly, even within the same risk quantile, the value premium still exists. The results suggest that risk and behavioral factors simultaneously cause the value premium. Furthermore, by decomposing the holding period return, I find that adjustments in valuation ratios caused by negative earnings surprises for growth firms and positive earnings surprises for value firms at least partially lead to the value premium.
