An Analysis of Market Efficiency for Exchange-traded Foreign Exchange Options on an Intraday Basis

Description: This study examines the comparative magnitude of disturbances in intraday data for exchange traded foreign exchange (FX) options. An in-depth time series analysis on the frequency and extent of discrepancies in the disturbances is conducted. The purpose of this study is twofold. First, using intraday data and trading volume, this study attempts to determine whether both put-call parity and lower boundary conditions consistently hold for exchange traded options written on U.S. dollar denominated options on the Euro trading on the Philadelphia Stock Exchange (PHLX). Second, this study attempts to investigate the magnitude of any discrepancies that may exist due to a temporary cessation of either put-call parity or lower boundary conditions. Intraday (tick-by-tick) bid prices, ask prices, and trading volume on U.S. dollar denominated European style call options and put options on the Euro are obtained. Option data is collected through a Structured Query Language (SQL) request from the Bloomberg database. Corresponding tick-by-tick spot rates for the underlying exchange rate are obtained for the same time period. Tick-by-tick 3-month Treasury bill rates are obtained to for use as the relevant risk-free interest rate. The primary data set spans an approximate one month period from 11/1/2011 to 12/6/2011. Call and option pricing data for near-the-money exercise prices are obtained for options expiring in December 2011, January 2012, February 2012, March 2012, June 2012, and September 2012. A total of 7,212 ticks (minutes) are analyzed for the conversion strategy and 7,209 ticks are analyzed for the reversal strategy. The data is structured into an unbalanced panel data set (cross-sectional time series data) using put-call pairs as the cross sectional units and ticks as the time-series unit. To test the efficiency of the foreign exchange options market, lower boundary and put-call parity conditions were tested on tick-by-tick currency option data. Analysis shows that ...

An Analysis of Preferred Equity Redemption Cumulative Stock

Description: This dissertation examines whether Percs, Preferred Equity Redemption Cumulative Stocks, are properly priced regarding to the relevant securities, such as the underlying common stock, the long-term call option of the stock, and so on. Test results indicate that Percs were overpriced with respect to the equivalent packages composed of the relevant securities. Further tests on arbitrage restrictions show that transaction costs would prevent arbitrage profits. This dissertation also examines the market reactions to Percs offerings. Test results reveal that the market reactions to the announcement of Percs offering and the actual issuance are both significantly negative. Compared to the market reaction on common stock offering announcement, the market reaction on Percs offering announcement is weaker. The overpricing of Percs and the weaker reaction of the market suggest that Percs may have advantages in transaction costs, taxes and some corporate finance issues.

Arbitrage Pricing Theory and the Capital Asset Pricing Model: Evidence from the Eurodollar Bond Market

Description: Monthly returns on twenty-seven Eurobonds from July 1982 to June 1986 were examined. There were no consistent differences in returns based on the country in which a firm is located. There were consistent differences due to industry classification, with energy-related firms exhibiting higher average returns and variances. Excess returns were calculated using the capital asset pricing model and arbitrage pricing theory. The results from calculation of mean average deviation, root mean square, and R2 all indicate that the arbitrage pricing theory was a better descriptor of the Eurobond market. The excess returns were also examined using stochastic dominance. Arbitrage pricing theory never dominated the capital asset pricing model using first-order criteria, but consistently dominated using second-order criteria. The results were discussed in terms of the implications for investors and portfolio managers.

Corporate Sale-and-Leaseback Transactions: An Examination of Corporate Incentives, Wealth Effects and Dealer Spreads

Description: There is a limited amount of research dealing with the wealth effects of sale-and-leaseback transactions, but previous research has focused predominantly on the tax effects of these transactions. The results of these studies have often been in conflict with one another. This dissertation shows that tax effects do play a role in determining the wealth effect of sale-and-leasebacks on stockholders, but there exists a framework of finance research that suggests several other factors could play a determining role as well.

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

Description: 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 strategies. Among the various alternatives to hedging are modifying the firm's capital structure, purchasing insurance, and modifying dividend policy. The amount of off-balance-sheet hedging activity undertaken by a specific firm is therefore a function of the value of hedging to the firm and the degree to which the firm has used alternatives to hedging. Using a regression analysis, this paper provides empirical evidence on the preceding relations. This study provides (1) the first empirical evidence into the reasons for a value-maximizing firm using off-balance-sheet hedging instruments, and (2) empirical insights into the way in which the firm's hedging decision interrelates ...

Determinants of Outbound Cross-border Mergers and Acquisitions by Emerging Asian Acquirers

Description: This dissertation identifies key determinants of outbound cross-border mergers and acquisitions (M&As) by emerging Asian acquirers during 2001-2012. Using a zero-inflated model that takes into account different mechanisms governing country pairs that never engage in cross-border M&As and country pairs that actively participate in cross-border M&As, I uncover unique patterns for emerging Asian acquirers. Emerging Asian acquirers originate from countries with lower corporate tax rates than those countries where their targets are located. Furthermore, the negative impact of an international double tax burden is significantly larger than that found in previous studies. While country governance differences and geographical and cultural differences are important determinants of international M&As, relative valuation effects are muted. Coefficients of these determinants vary substantially, depending on whether targets are located in developing or advanced nations. Also, determinants differ considerably between active and non-active players in cross-border M&As. Moreover, comparisons of empirical models illustrate that estimating a non-linear model and taking into account both the bounded nature and non-normal distributions of fractional response variables lead to different inferences from those drawn from a linear model estimated by the ordinary least squares method. Overall, emerging Asian acquirers approach the deals differently from patterns documented in developed markets. So, when evaluating foreign business combinations or devising policies, managers or policymakers should consider these differences.

The Effects of Stock Delistings on Firm Value, Risk, Market Liquidity and Market Integration: With Evidence on Wealth Effects from the Stock Exchanges of Malaysia and Singapore, Using GARCH

Description: This study examines the effects of delisting on firm value, risk and market liquidity. In a world where markets are becoming increasingly integrated, delistings may prove counter productive. We use the unique event, free from company specifics, that occurred on January 2, 1990 in the stock exchanges of Singapore and Malaysia to test for the above effects. On that day, dual listed companies were required to delist from the foreign stock exchange. We also use this event to test if the Singapore and Malaysia markets are globally integrated. Since financial data is found to show persistence in volatility, we model the return generating process in a generalized autoregressive conditionally heteroskedastic (GARCH) framework that takes into consideration changing volatility. For comparison purposes, OLS and Time-Deformation models are included. The study found delistings to decrease firm value, the size of which is related to how actively the stocks were previously traded on the foreign stock exchange. Risk levels increased following delistings. Nevertheless, thinly traded stocks showed significant changes in neither firm value nor riskiness. Further evidence of new listings to increase firm value was noted. Consistent with the political motive hypothesis, delisted stocks showed an increase in post-event volume, but however, lost relative liquidity compared with other stocks. While all portfolios considered show evidence for existence of conditional heteroskedasticity, comparison with standard OLS event-study results yields similar conclusions, although the return generating models with GARCH errors result in lower abnormal return variances. As for the time-deformation model, trading volume was found to be a good proxy for rate of information flow only for smaller capitalized stocks. Correlation and regression analyses showed that the Singapore and Malaysia markets are integrated to some degree with the international markets, such that a major delistings event between both markets did not change the pricing of risk ...

Information Content of Iron Butterfly Arbitrage Bounds

Description: 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 traded stock options attains its highest level immediately after the open of the market, declines steadily throughout the first trading hour and remains relatively stable until market close. However, index IBBs behave differently. S&P 500 index option IBB attains its lowest level during the first hour of the trading day, then increases and remains relatively stable until market close. I present new evidence regarding the dynamic relation between stock returns and innovations in expected volatility by using the minute-by-minute change in implied volatility (IV) as a proxy. Unlike the relationship between individual stock returns and their respective changes in implied ...

Information Content of Managerial Decisions, Change in Risk, and Complimentary Signals: Evidence on New Bond Issue, Exchange Offer, and Dividend Payments

Description: The effect of a change in capital structure on the risk and return of common stockholders is investigated. Also, the information content of dividends when a firm goes for new outside financing is examined. Data used in the study are collected from the Moody's Bond Survey, the Prentice Hall's Capital Adjustments, the Wall Street Journal Index, and the Center for Research in Security Prices Tape. The study uses an event study methodology. The risk (beta) of common stock before an issuance of debt securities is compared with the risk after the issue. The stock market reaction to the issuance of new debt securities is measured using after-the-event risk. The information content of dividend announcement before a new debt issue is compared to that of after the issue. The findings show that debt issue reduces stock holders' risk if the issuer is a dividend paying company. Also, debt securities issued through an exchange offer increase stockholders' wealth. Finally, issuance of new debt does not affect the information content of dividends.

The Information Content of Pension Fund Asset Reversion

Description: Prior studies on the impact of the termination of overfunded defined benefit pension plans on shareholders' wealth have produced conflicting findings. The first study on the stock market reaction to pension plan termination was conducted by Alderson and Chen (1986); this study claimed that shareholders realize significant positive abnormal returns around the termination announcement date. A more recent study, by Moore and Pruitt (1990), disclaimed the findings of Alderson and Chen. Reexamination of these two studies with additional evidence and the use of the appropriate announcement date suggests that termination of pension plans is associated with significant wealth gain to shareholders. This study also analyzes samples from periods prior to and after the imposition in 1986 of a 10 percent excise tax on recaptured excess pension assets. The empirical results suggest that shareholders experience significant positive wealth effects for the pre-tax (1980-85) period and no wealth effects for the post-tax (1986-88) period. The primary purpose of this study is to determine the impact of stock market reaction upon shareholders' wealth under the partial anticipation hypothesis. The pre-tax sample is analyzed by isolating the expected terminators using the multiple discriminant analysis model. This study finds significant positive abnormal returns only for firms that are not anticipated by the investors as potential terminators. The results of this study do not lend support to either the "separation" or the "integration" hypothesis as proposed by Alderson and Chen (1986). Instead, the results are consistent with the information hypothesis that the market reacts to unanticipated events that provide new information. Cross-sectional regression analysis of unexpected terminators suggests that the abnormal performance of stocks of pension terminating firms is explained by the firms' debt ratio and the amount of surplus pension assets. It can be inferred that firms may resort to recapturing excess pension assets as ...

Innovation Output and the Cost of Funds

Description: 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 to be more important to shareholders than short-term changes of innovation. In addition, shareholders demonstrate an ability to discern between low and high-quality innovations, as they require lower rates of returns when initial patents exhibit a high quality. Shareholders place more value on innovation output when firms operate in countries with legal systems that are more effective in controlling self-dealing practices, in countries that have higher economic freedom, and in countries that have more developed financial markets. The correlation between the cost of debt and innovation output is predominantly derived by larger, more mature, and more leveraged firms. Innovation output ...

Is 100 Percent Debt Optimal? Three Essays on Aggressive Capital Structure and Myth of Negative Book Equity Firms

Description: This dissertation comprises of three related essays in regard of puzzling negative book equity phenomenon among U.S. public firms. In essay 1, I present the evidence that there is an increasing trend of negative book equity firms over the past 50 years, from 0.3% up to over 5% among publicly traded firms in US. In contrast to previous research which generally classify these firms as distressed firms with highly likelihood of bankruptcy, I propose a new method to separate Healthy Negative Book Equity Firms (HNBEF) from relatively more distressed negative book equity firms. The results show that HNBEF have much higher net income and interest coverage ratio, they survive longer, and pay more dividends. More interestingly, these firms are often actively increase share repurchases and debt issuance. These facts, combined with their strong profitability, indicate that managers of these firms are actively increasing their leverage and choose to be negative book equity firms. To explain the existence of HNBEF, in essay 2, I investigate several possible reasons that may contribute to the extreme leverage of these firms. I find that HNBEF are substantially undervalued by their book assets as stated on the balance sheet. In addition, the value of intangible assets, especially those off-balance sheet intangible assets, is positively related to the probability of becoming HNBEF. Moreover, I find that characteristics of intangible assets and firms also play important role on existence of HNBEF. Specifically, I find that both liquidity and redeployability of intangible assets are positively related with the probability of becoming HNBEF. Also, firms associated with closer borrower-lender relationship are more likely to become HNBEF. To investigate if the aggressive capital structure adopted by HNBEF is optimal, in essay 3, I performed several tests to analyze how these firms differ from other firms in terms of operating performance, ...

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

Description: 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 are availability of substitutes and financial constraints. The former arises as a result of the specialization of arbitrageurs in the market in which they operate, while the latter arises as a result of the separation between arbitrageurs and capital. In this dissertation, I develop a measure of the availability of substitutes that is based on the propensity scores obtained from propensity score matching technique. In addition, I use the absolute value of skewness of returns as a proxy of financial constraints. Previous studies used the limits of arbitrage framework to explain pricing puzzles such as the closed-end fund discounts. However, ...

Locational Determinants of Real Estate Valuation: an Analysis of Spatial Autocorrelation in the Hedonic Pricing of Real Estate

Description: Recent studies of the valuation of real estate have concentrated on the use of hedonic pricing techniques in which the implicit prices of the component characteristics of an asset are inferred from the observed sale price using regression analysis. All of these studies include as explanatory variables one or more locational factors, such as distance to the central business district, as proxies for the effect that location has on the utility of land. In this research, the explicit consideration of the location of real estate in terms of the geographic or Cartesian coordinates (spatial attributes) of observed sales is shown to be a potential substitute for such proxies, either wholly or in part. Such use of spatial attributes could improve the usefulness of the hedonic methodology while at the same time significantly reducing cost and eliminating sources of error.

Market Efficiency, Arbitrage and the NYMEX Crude Oil Futures Market

Description: Since Engle and Granger formulated the concept of cointegration in 1987, the literature has extensively examined the unbiasedness of the commodity futures prices using the cointegration-based technique. Despite intense attention, many of the previous studies suffer from the contradicting empirical results. That is, the cointegration test and the stationarity test on the differential contradict each other. In marked contrast, my dissertation develops the no-arbitrage cost-of-carry model in the NYMEX light sweet crude oil futures market and tests stationarity of the spot-futures differential. It is demonstrated that the primary cause of the "cointegration paradox" is the model misspecifications resulting in omitted variable bias.

Predictability of Credit Watch Placements and the Distribution of Wealth Effects Across the Trigger Event, Placement and Removal Dates

Description: Standard and Poor's began publication of Credit Watch in November of 1981 as an early warning list for firms whose debt is under review for a possible rating change. This dissertation is composed of three essays which address various aspects of Credit Watch and the impact on shareholder wealth. The first essay uses a discriminant analysis model to classify the Credit Watch status of firms which engaged in mergers and acquisitions activity in 1991. The model correctly classifies 69.85% of the in-sample firms and 65.83% of the out of sample firms. The second essay examines whether the stock market reacts more strongly to trigger events which cause Credit Watch placements than to the actual placement. Significantly larger negative abnormal return are found around the trigger event than the placement. No evidence is found for the differential reaction evolving over time. The third essay examines firm specific and economy-wide factors which may be related to the strength of the abnormal stock return around the Credit Watch removal date. The removal return is found to be positively related to the number of trading days a firm remains on Credit Watch, negatively related to the number of updates regarding the firm released by Standard and Poor's while on the list, and positively related to the cumulative abnormal return measured between the placement and removal. This evidence suggests that the number of trading days a firm remains on Credit Watch is a proxy for information leakage to the market. The negative relationship between the removal return and the number of updates implies that the market reacts to a string of negative news of which the removal announcement is the final announcement. Finally, the positive relationship with the cumulative abnormal return between placement and removal suggests that much of the information content of the removal ...

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

Description: 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 Reasons for the Divergence of IPO Lockup Agreements

Description: Most initial public offerings (IPOs) feature share lockup agreements, which prohibit insiders from selling their shares for a specified period of time following the IPO. However, some IPO firms agree to have a much longer lockup period than other IPO firms, and some are willing to lockup a much larger proportion of shares. Thus, the primary research question for this study is: "What are the reasons for the divergence of the lockup agreements?" The two main hypotheses that this dissertation investigates are the signaling hypothesis based on information asymmetry, and the commitment hypothesis based on agency theory. This study uses methods that have not been applied by previous studies in the literature relating to IPO lockups. First, I directly use IPO firms operating performance as a proxy for firm quality. The results show neither a negative nor a strong positive relationship between lockup length and firm operating performance. Thus, based on operating performance, the evidence does not support the agency hypothesis while showing weak support for the signaling hypothesis. I then examine the long-run returns for IPO firms with different lockup lengths. I find that firms with short lockup lengths have much better long-run returns than firms with long lockup lengths. Therefore, the results reject the signaling hypothesis while supporting the agency hypothesis. This dissertation further contributes to the IPO long-run underperformance literature by showing that firms with a high agency problem have much worse long-run returns than those with a low agency problem. Finally, I investigate the short-term stock returns around lockup expiry. Generally, I find that firms with short lockup periods experience better stock returns around lockup expiry than firms with long lockup periods, though the returns are not significantly different from one another. Overall, I conclude that the results reject the signaling hypothesis while partially supporting the ...

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

Description: 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 exchange are estimated using various techniques. No hedge ratio technique examined consistently outperforms the unhedged portfolio in terms of variance reduction. Consequently, none of the hedge ratio methods in this study meet the general interpretation of FASB guidelines for a highly effective hedge. One of the major goals of deregulation is to bring about competition and increased efficiency in electricity markets. Previous research suggests that electricity exchanges may not be weak-form market efficient. A simple moving average trading rule is found to produce statistically and economically significant profits on the MISO exchange. This could call the long-term survivability of the ...

Significant Alphas in Real Estate Funds

Description: This study provide empirical evidence whether bias in the standard errors of Jensen’s alpha explains conflicting results in the extant literature in real estate funds. Significant alphas in real estate mutual funds and REITs are compared with heteroskedasticity consistent covariance matrix estimators (HC1, HC2 and HC3), Newey-West standard errors, a robust regression tempering the effect of high leverage points, a GARCH model, and a HC3 adjusted wild bootstrap. In the analysis of real estate mutual funds and a separate sample set of REITs, the HCCME had a minimal impact attenuating the number of firms with excess returns. Contrary to expectations the differences from HC1 to HC2 to HC3 were also negligible. The Newey-West standard error provided highly variable results when compared with the OLS results particularly in the REIT sample. Of the techniques to adjust for bias in the standard error, the wild bootstrap with HC3 adjustment to the standard error provided the most conservative result to the number of real estate mutual funds and REITs with significant alphas. The co-movement of real estate funds suggests common exogenous influences. Including state variables such as the changes in unexpected inflation, term spread, default spread, market skewness and industrial production growth in a multi-factor model is used to identify systemic economic factors in significant alphas. The significant alphas varied with the inclusion of these variables, the time period and the bias adjustment.

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

Description: 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 for determining multiple notch downgrades are a firm’s prior rating change, prior rating, current ratio, interest coverage, total debt, operating margin, market to book ratio, capital expenditure, total assets, market value, and market beta. The variables that differ for multi notch upgrades in recessions are cash flow, net income, operating margin, market to book ratio, total assets, and retained earnings. The variables that differ for multi notch downgrades in expansions are a firm’s prior rating change, current ratio, interest coverage ratio, debt ratio, total debt, capital expenditure and market beta. The power of the explanatory tests improves when the stage ...

Three Essays in Corporate Governance

Description: 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 of votes cast in favor of the proposal and levels of institutional ownership. There is an inverse relationship between the percentage of votes and managerial ownership and firm size. Large firms with powerful owner-managers present the greatest obstacle to the success of shareholder proposals. The repeal of shareholder rights plans is one of the most frequently used shareholder proposals. By adopting the rights plan, managers increase the probability of defeating a takeover, but increase their power in negotiating with a potential acquiring firm. In the third essay, I find that firms who combine a rights plan with high debt levels ...

Time Series Analysis of Going Private Transactions: Before and after the Sarbanes-Oxley Act

Description: Using 1,473 going private transactions completed between 1985 and 2007, I assess whether the increase in going private transactions that occurred after the passage of the Sarbanes-Oxley Act of 2002 (SOX) was driven by SOX, or whether this phenomenon continues an ongoing historical trend. To examine this issue, I initially used structural break tests and intervention analysis. From the initial techniques, I find support that the passage of SOX increased going private transactions for these categories. Secondarily, I use Granger causality tests and impulse response functions to examine the link between going private transactions and the public stock market. When I categorize going private transactions according to the type of acquirer, transaction size, and target industry, I find bi-directional Granger causality relationships between smaller-sized going private transactions and the S&P 500 Index (or Tobin's Q). I also find several unidirectional Granger causality relationships for some categories of going private transactions, based on the type of acquirer or the target industry, to the S&P 500 Index (or to Tobin's Q). The impulse response of going private transactions (or the public stock market) to a shock in the public stock market (or going private transactions) is not immediate, but is delayed two to three quarters. The link between going private transactions and the public stock market is an ongoing phenomenon, continuing a historical trend for going private transactions. For going private transactions with structural breaks, SOX affects the linkage but not for going private transactions with no structural break.
