Three Essays in Corporate Governance (open access)

Three Essays in Corporate Governance

Corporate governance issues have become increasingly important to financial managers and shareholders. Firms that are plagued by poor performance, incompetent managers, or excess agency costs have become the subject of a dramatic increase in shareholder activism. Dissident shareholders, who are unable to launch costly takeover bids or proxy contests, have initiated a process of governance reform through the use of shareholder sponsored proposals. Shareholder proposals are a direct attempt to reverse operating or voting policies, such as a proposal to repeal a classified board. Managers announce shareholder proposals in a proxy statement and typically include a vote recommendation against the proposal. In the first essay, I find an unfavorable stock price reaction to the announcement of a shareholder proposal. In some cases, however, management supports the proposal and negotiates an agreement with the proposing shareholder. Stock prices react favorably to a settlement announcement. If managers are willing to negotiate with shareholders, they are perceived to be acting in the best interest of shareholders. If managers are unwilling, shareholders believe a severe agency problem exists. In the second essay, the effect that ownership structure has on voting outcomes of shareholder proposals is examined. I find a direct relationship between the percentage …

Purchasing Power Parity and the Efficient Markets: the Recent Empirical Evidence (open access)

Purchasing Power Parity and the Efficient Markets: the Recent Empirical Evidence

The purpose of the study is to empirically determine the relevance of PPP theory under the traditional arbitrage and the efficient markets (EPPP) frameworks during the recent floating period of the 1980s. Monthly data was collected for fifteen industrial nations from January 1980 to December 1986. The models tested included the short-run PPP, the long-run PPP, the EPPP, the EPPP with deviations from expectations, the forward rates as unbiased estimators of future spot rates, the EPPP and the forward rates, and the EPPP with forward rates and lagged values. A generalized regression method called Seemingly Unrelated Regression (SUR) was employed to test the models. The results support the efficient markets approach to PPP but fail to support the traditional PPP in both the short term and the long term. Moreover, the forward rates are poor and biased predictors of the future spot rates. The random walk hypothesis is generally supported.

The Determinants of Off-Balance-Sheet Hedging in the Value-Maximizing Firm: an Empirical Analysis (open access)

The Determinants of Off-Balance-Sheet Hedging in the Value-Maximizing Firm: an Empirical Analysis

The observed use (and indeed tremendous growth in volume) of forward contracts, futures, options, and swaps as hedges against interest rate risk, foreign exchange risk, and commodity price risk indicates that hedging does add value to the firm. The purpose this research was to empirically examine the value of off-balance-sheet hedging. The benefits of off-balance-sheet hedging were found to accrue from reducing (1) taxes, (2) expected financial distress costs, and (3) agency costs. Taxes. Hedging reduces the firm's tax liability by reducing the variability in taxable income. The value of hedging to the firm is a positive function of the convexity of the tax function and the variability of taxable income. Expected Financial Distress Costs. The value of hedging is a positive function of the degree to which hedging reduces the probability of financial distress and the costs of financial distress. Agency Cost. Due to the fact that bondholders and some managers hold fixed claims while shareholders hold variable claims, shareholders desire more risky projects than do bondholders or managers. Hedging reduces this conflict by allowing shareholders to undertake higher risk projects while protecting the holders of fixed claims. Firms can achieve the same benefits of hedging by using alternative …

The Effect of Stock Splits on Small, Medium, and Large-sized Firms Before and After Decimalization (open access)

The Effect of Stock Splits on Small, Medium, and Large-sized Firms Before and After Decimalization

This study examines the impact of reducing tick size and, in particular decimalization on stock splits. Based on previous studies, this study examines hypotheses in the following three areas: first, market reaction around stock split announcement and ex-dates, second, the effect of tick size on liquidity after stock split ex-dates, and third, the effect of tick size on return volatility after stock split ex-dates. The impact of tick size on market reaction around split announcement and ex-dates is measured by abnormal returns and buy and hold abnormal returns (BHARs). Also, this study investigates the long term impact of decimalization on market reaction for small, medium, and large firms for the three different tick size periods. The effect of tick size on liquidity after stock split ex-dates is measured by turnover, relative bid ask spread, and market maker count. The effect of tick size on return volatility around stock split announcement and ex-dates is measured by return standard deviation. Also, this study investigates the long term impact of decimalization on volatility after split ex-dates for small, medium, and large firms for three different tick size periods.

The Limits of Arbitrage and Stock Mispricing: Evidence from Decomposing the Market to Book Ratio (open access)

The Limits of Arbitrage and Stock Mispricing: Evidence from Decomposing the Market to Book Ratio

The purpose of this paper is to investigate the effect of the "limits of arbitrage" on securities mispricing. Specifically, I investigate the effect of the availability of substitutes and financial constraints on stock mispricing. In addition, this study investigates the difference in the limits of arbitrage, in the sense that it will lead to lower mispricing for these stocks, relative to non-S&P 500 stocks. I also examine if the lower mispricing can be attributed to their lower limits of arbitrage. Modern finance theory and efficient market hypothesis suggest that security prices, at equilibrium, should reflect their fundamental value. If the market price deviates from the intrinsic value, then a risk-free profit opportunity has emerged and arbitrageurs will eliminate mispricing and equilibrium is restored. This arbitrage process is characterized by large number of arbitrageurs which have infinite access to capital. However, a better description of reality is that there are few numbers of arbitrageurs to the extent that they are highly specialized; and they have limited access to capital. Under these condition arbitrage is no more a risk-free activity and can be limited by several factors such as arbitrage risk and transaction costs. Other factors that are discussed in the literature …

Single Notch Versus Multi Notch Credit Rating Changes and the Business Cycle (open access)

Single Notch Versus Multi Notch Credit Rating Changes and the Business Cycle

Issuers’ credit ratings change by one or more notches when credit rating agencies provide new ratings. Unique to the literature, I study the influences affecting multi notch versus single notch rating upgrades and downgrades. For Standard & Poors data, I show that rating changes with multiple notches provide more information to the market than single notch rating changes. Consistent with prior literature on the business cycle, I show that investors value good news rating changes (upgrades) more in bad times (recession) and that investors value bad news rating changes (downgrades) more in good times (expansion). I model and test probit models using variables capturing the characteristics of the previous issuer’s credit rating, liquidity, solvency, profitability, and growth opportunity to determine the classification of single notch versus multi notch rating changes. The determinants of multi notch versus single notch rating changes for upgrades and downgrades differ. Business cycle influences are evident. Firms that have multi notch rating upgrades and downgrades have significantly different probit variables vis-à-vis firms that have single notch rating upgrades and downgrades. The important characteristics for determining multiple notch upgrades are a firm’s prior rating change, prior rating, cash flow, total assets and market value. The important characteristics …

Innovation Output and the Cost of Funds (open access)

Innovation Output and the Cost of Funds

Do firms with higher levels of innovation output, measured by patent counts and citations, enjoy lower costs of funds? The process to develop and apply for patents involves valuable resources. Thus, applying for a patent is a credible signal that the underlying invention is valuable. This value is validated to some degree when the patent is granted. In addition, patents contain detailed information about the firm's inventions and provide collateral value as they can be sold and licensed. The number of citations a firm receives act as a proxy for high-quality inventions, active networking, and pioneering. These attributes are expected to attract investors and reduce the cost of funds. Univariate and cross-sectional regression analyses of a sample consisting of 404,595 firm-years, involving firms from twenty-eight countries spanning from 1976 to 2012, demonstrate a significant negative association between innovation output and the cost of funds. The evidence suggests that the marginal benefit of innovation diminishes as innovation output increases. The results are robust to different measures of the cost of equity and the cost of debt. The negative association between the cost of equity and innovation output is economically larger for younger and smaller firms. The long-term level of innovation seems …

The Application of Statistical Classification to Business Failure Prediction (open access)

The Application of Statistical Classification to Business Failure Prediction

Bankruptcy is a costly event. Holders of publicly traded securities can rely on security prices to reflect their risk. Other stakeholders have no such mechanism. Hence, methods for accurately forecasting bankruptcy would be valuable to them. A large body of literature has arisen on bankruptcy forecasting with statistical classification since Beaver (1967) and Altman (1968). Reported total error rates typically are 10%-20%, suggesting that these models reveal information which otherwise is unavailable and has value after financial data is released. This conflicts with evidence on market efficiency which indicates that securities markets adjust rapidly and actually anticipate announcements of financial data. Efforts to resolve this conflict with event study methodology have run afoul of market model specification difficulties. A different approach is taken here. Most extant criticism of research design in this literature concerns inferential techniques but not sampling design. This paper attempts to resolve major sampling design issues. The most important conclusion concerns the usual choice of the individual firm as the sampling unit. While this choice is logically inconsistent with how a forecaster observes financial data over time, no evidence of bias could be found. In this paper, prediction performance is evaluated in terms of expected loss. Most …

An Empirical Analysis of Stock Market Anomalies and Spillover Effects: Evidence from the Securities Exchange of Thailand (open access)

An Empirical Analysis of Stock Market Anomalies and Spillover Effects: Evidence from the Securities Exchange of Thailand

This study examines two interrelated but separate issues: cross-sectional predictability of equity returns in the Stock Exchange of Thailand (SET), and transmission of stock market movements. The first essay empirically investigates to what extent the evidence of three major documented stock market anomalies (earnings-price ratio, firm size, and book-to-market ratio) can be generalized across national stock markets. The second essay studies the price and volatility spillover effects from the New York Stock Exchange (NYSE) to the SET. The first essay, using the Fama-Macbeth procedure and the pooled time-series cross-sectional GLS regressions, finds a weak relation between the beta and average stock returns. The adjustment of estimated beta for the effect of thin trading does not change the implications of the results. Of the three anomalies investigated, the size effect has the most prominent and consistent role in explaining average returns. For the earnings-price ratio, the results indicate that the significance of the E/P ratio variable persists only if the nonfinancial firms are considered. In contrast to the previous empirical results for the U.S. and Japanese stock markets, the book-to-market ratio fails to explain the SET equity returns. The second essay employs a generalized autoregressive conditionally heteroskedastic (GARCH) model with conditional …

Market Timing, Forecast Ability and Information Flow in Petroleum Futures Markets (open access)

Market Timing, Forecast Ability and Information Flow in Petroleum Futures Markets

Three petroleum futures contracts are examined over a ten-year period from 1986 to 1996. Intertemporal changes in futures prices and the net open interest positions of three trader types are compared to determine what, if any, market timing ability the traders have. Seasonal variation is considered and a simple trading rule is adopted to determine the dollar-return potential for market participation and shed light on issues of market efficiency.

Changes in Trading Volume and Return Volatility Associated with S&P 500 Index Additions and Deletions (open access)

Changes in Trading Volume and Return Volatility Associated with S&P 500 Index Additions and Deletions

When a stock is added into the S&P 500 Index, it is automatically "cross-listed" in the index derivative markets (i.e., S&P 500 Index futures and Index options). I examined the effects of such cross-listing on the trading volume and return volatility of the underlying component stocks. Traditional finance theory asserts that futures and "cash" markets are connected by arbitrage mechanism that brings both markets to equilibrium. When arbitrage opportunities arise, arbitrageurs buy (sell) the index portfolio and take short (long) positions in the corresponding index derivative contracts until prices return to theoretical levels. Such mechanical arbitrage trading tends to create large order flows that could be difficult for the market to absorb, resulting in price changes. Utilizing a list of S&P 500 index composition changes occurring over the period September 1976 to December 2005, I investigated the market-adjusted volume turnover ratios and return variances of the stocks being added to and deleted from the S&P 500, surrounding the effective day of index membership changes. My primary finding is that, after the introduction of the S&P 500 index futures and options contracts, stocks added to the S&P 500 experience significant increase in both trading volume and return volatility. However, deleted stocks …

Crude Oil and Crude Oil Derivatives Transactions by Oil and Gas Producers. (open access)

Crude Oil and Crude Oil Derivatives Transactions by Oil and Gas Producers.

This study attempts to resolve two important issues. First, it investigates the diversification benefit of crude oil for equities. Second, it examines whether or not crude oil derivatives transactions by oil and gas producers can change shareholders' wealth. With these two major goals in mind, I study the risk and return profile of crude oil, the value effect of crude oil derivatives transactions, and the systematic risk exposure effect of crude oil derivatives transactions. In contrast with previous studies, this study applies the Goldman Sachs Commodity Index (GSCI) methodology to measure the risk and return profile of crude oil. The results show that crude oil is negatively correlated with stocks so adding crude oil into a portfolio with equities can provide significant diversification benefits for the portfolio. Given the diversification benefit of crude oil mixed with equities, this study then examines the value effect of crude oil derivatives transactions by oil and gas producers. Differing from traditional corporate risk management literature, this study examines corporate derivatives transactions from the shareholders' portfolio perspective. The results show that crude oil derivatives transactions by oil and gas producers do impact value. If oil and gas producing companies stop shorting crude oil derivatives contracts, …

Bank Loans as a Financial Discipline: A Direct Agency Cost of Equity Perspective

Access: Use of this item is restricted to the UNT Community
In a 2004 study, Harvey, Lin and Roper argue that debt makers with a commitment to monitoring can create value for outside shareholders whenever information asymmetry and agency costs are pronounced. I investigate Harvey, Lin and Roper's claim for bank loans by empirically testing the effect of information asymmetry and direct agency costs on the abnormal returns of the borrowers' stock around the announcement of bank loans. I divide my study into two main sections. The first section tests whether three proxies of the direct agency costs of equity are equally significant in measuring the direct costs associated with outside equity agency problems. I find that the asset utilization ratio proxy is the most statistically significant proxy of the direct agency costs of equity using a Chow F-test statistic. The second main section of my dissertation includes and event study and a cross-sectional analysis. The event study results document significant and positive average abnormal returns of 1.01% for the borrowers' stock on the announcement day of bank loans. In the cross sectional analysis of the borrowers' average abnormal stock returns, I find that higher quality and more reputable banks/lenders provide a reliable certification to the capital market about the low …

Reconciling capital structure theories in predicting the firm's decisions.

Access: Use of this item is restricted to the UNT Community
Past literature attempts to resolve the issue of the motivation behind managers' choice of a given capital structure. Despite several decades of intensive research, there is still no consensus about which theory dominates capital structure decisions. The present study empirically investigates the relative importance of two prominent theories of capital structure- the trade-off and the pecking order theories by exploring the conditions under which each theory can explain the financing choices of firms. These conditions are defined along two dimensions: (i) a firm's degree of information asymmetry, and (ii) its observed leverage relative to target leverage. The results show that, in the short-run, pecking order theory has more explanatory power in explaining the financing choices of firms. The target leverage theory assumes limited importance: Over-leveraged firms, when faced with low adverse information, are more inclined to adapt to the trade-off policies. In the presence of high information asymmetry, however, firms appear to be more concerned about adverse selection costs and make financing decisions that are more consistent with the pecking order theory. An analysis of the market reaction to seasoned equity issuances during announcement periods reveals that firms with high information asymmetry are penalized more than firms with low information …

Does the Method of Financing Stock Repurchases Matter? Examining the Financing of Share Buybacks and Its Effect on Future Firm Investments and Value (open access)

Does the Method of Financing Stock Repurchases Matter? Examining the Financing of Share Buybacks and Its Effect on Future Firm Investments and Value

Recent increases in stock repurchases among U.S. corporations coupled with a historically low cost of debt since the Global Financial Crisis has created media speculation that firms in recent years are paying for their expanding share buyback programs with debt. Repurchasing stock by increasing leverage, instead of using internal funds, implies that managers may speculate on current low interest rate environments at the expense of shareholders. Recent studies find that stock repurchases are associated with reductions in future firm employment and investments such as capital expenditures and research and development expenses. This study expands on prior studies by evaluating how debt-financed stock repurchases affect firm investment, investigating the likelihood of these repurchases in low interest rate environments and assessing the effects on firm value. Results confirm that, in recent years, debt-financed repurchases have increased substantially and the probability of debt-financed repurchases increases in the presence of low interest rates. This relationship is especially pronounced in the years following the Global Financial Crisis. Debt-financed repurchases are associated with small reductions in firm investment; however, these reductions are significantly less after adjusting for industry conditions. Finally, there is little evidence that the method of financing repurchases affects firm value nor does it …

Information Content of Iron Butterfly Arbitrage Bounds (open access)

Information Content of Iron Butterfly Arbitrage Bounds

Informed traders trade options on underlying securities to lower transaction costs and increase financial leverage for price trend and variance strategies. Options markets play a significant role in price discovery by incorporating private information about future prices for an underlying security into option prices. I generate a new model-free volatility measure to calculate the "distance from arbitrage bounds" from minute-by-minute option series for the S&P 500 index and 30 individual underlying stocks. These iron butterfly arbitrage bounds (IBBs) use intraday call and put option prices from the Bloomberg database. Narrow and wide IBBs are expected to reveal the options market valuation of volatility by market participants. Data series is gathered by using successive one-minute intervals from the Bloomberg database. The data comprise the most recent bid and ask option prices and volumes. I collect S&P 500 index values and index options and use 30 underlying stock prices and option prices for the contracts that have the largest option trading volume during the sampling interval. These bid and ask prices reflect the information generated by intraday price pressures implied by S&P 500 index options or stock options. Consistent with the option micro-structure literature, I find that the IBB measure for actively …

Economic Motivation of the Ex-Dividend Day Anomaly: Evidence from an Alternative Tax Environment (open access)

Economic Motivation of the Ex-Dividend Day Anomaly: Evidence from an Alternative Tax Environment

Several studies have observed that stocks tend to drop by an amount that is less than the dividend on the ex-dividend day, the so-called ex-dividend day anomaly. However, there still remains a lack of consensus for a single explanation of this anomaly. Different from other studies, this dissertation attempts to answer the primary research question: How can investors make trading profits from the ex-dividend day anomaly and how much can they earn? With this goal, I examine the economic motivations of equity investors through four main hypotheses identified in the anomaly’s literature: the tax differential hypothesis, the short-term trading hypothesis, the tick size hypothesis, and the leverage hypothesis. While the U.S. ex-dividend anomaly is well studied, I examine a long data window (1975 to 2010) of Thailand data. The unique structure of the Thai stock market allows me to assess all four main hypotheses proposed in the literature simultaneously. Although I extract the sample data from two data sources, I demonstrate that the combined data are consistently sampled. I further construct three trading strategies: “daily return,” “lag one daily return,” and “weekly return” to alleviate the potential effect of irregular data observation. I find that the ex-dividend day anomaly exists …

Risk Management And Market Efficiency On The Midwest Independent System Operator Electricity Exchange. (open access)

Risk Management And Market Efficiency On The Midwest Independent System Operator Electricity Exchange.

Midwest Independent Transmission System Operator, Inc. (MISO) is a non-profit regional transmission organization (RTO) that oversees electricity production and transmission across thirteen states and one Canadian province. MISO also operates an electronic exchange for buying and selling electricity for each of its five regional hubs. MISO oversees two types of markets. The forward market, which is referred to as the day-ahead (DA) market, allows market participants to place demand bids and supply offers on electricity to be delivered at a specified hour the following day. The equilibrium price, known as the locational marginal price (LMP), is determined by MISO after receiving sale offers and purchase bids from market participants. MISO also coordinates a spot market, which is known as the real-time (RT) market. Traders in the real-time market must submit bids and offers by thirty minutes prior to the hour for which the trade will be executed. After receiving purchase and sale offers for a given hour in the real time market, MISO then determines the LMP for that particular hour. The existence of the DA and RT markets allows producers and retailers to hedge against the large fluctuations that are common in electricity prices. Hedge ratios on the MISO …
