Years ago it was typical for a physician to serve as a hospital's Chief Executive Officer (CEO). However, with the development of Master of Health Administration, Master of Public Health, and Master of Business Administration programs, hospitals began to move away from this model. Today however, as hospitals search for innovative ideas to reduce healthcare costs and improve the quality of care, the idea of the physician hospital CEO has returned. Little empirical research is available in the health services literature on the physician hospital CEO. The study aims to examine the relationship between organizational and environmental factors and physician CEOs, and whether or not physician CEOs are associated with improved hospital performance.The conceptual framework is adapted from Donabedian's structure, process, and outcome perspective, which when applied to the organizational level becomes context design-performance. The theoretical perspective applied to the conceptual framework to guide the development of hypotheses is contingency theory, which suggests that organizations are most successful when they can adapt their structures to fit their environment.Data for this study were obtained from multiple sources: American Hospital Association Annual Survey, the Centers for Medicare and Medicaid Services Hospital Cost Reports, SK&A, Area Resource File, and the Centers for Medicare and Medicaid Services Hospital Quality Alliance.Besides descriptive analyses, logistic regression was used in this study to evaluate the relationship between the organizational and environmental hospital characteristics. Ordinary least squares regression was used to explore the relationship between physician CEOs and hospital performance.Results indicate that hospitals in markets with greater physician competition are more likely to have physician CEOs. Hospitals that are affiliated with a system are also more likely to have physician CEOs. The study found that while teaching hospitals and specialty hospitals were associated with placement of physician CEOs, it was in the opposite direction of what was hypothesized. This may be a result of the small sample size of both teaching and specialty hospitals in the study sample. The study concludedthat having a physician CEOs is associated with hospital financial outcomes but not associated with its quality of care outcomes.

A financial function is one of the aspects of a business enterprise and a department that is involved with finances of the business is known as a financial department. Financial management, as a discipline, is interlinked with other activities that occur within a business organization such as production, marketing, purchasing, personnel functions, et cetera (Cronje, et. al. 1991:16,22). In a school organization there are different departments and committees, which are dependent on the financial committee of the institution for their survival. The finance committee focuses on making decisions with regard to the finances of the school and the generation of extra income, through alternative sources to add value to the organization, for the reason that schools cannot operate successfully with school fund only. Berkhout and Berkhout (1992:4) outline sources of finance that can assist the committee to generate more funds. For a school to operate and perform, the financial management function effectively, it is necessary for one to understand the internal and external environmental factors, which can affect the smooth running of the school. / Dr. P.J. du Plessis

This paper examines the relationship between national culture differences and five-day cumulative abnormal returns of acquirers around cross-border merger announcements. The sample consists of 1,200 cross-border deals by frequent acquirers from emerging countries for the period of January 1, 1985 to June 30, 2008. The main objective is to analyze the relation between the difference in Hofstede (1984)’s four cultural dimensions --- power distance, individualism, masculinity, and uncertainty avoidance and the merger performance. The results imply the compatibility of some cultural dimensions, individualism in particular, that result in gains in merger. The results also show that the cultural effects vary with the firm size. In addition, the evidence provides support for the hubris hypothesis by Roll (1986).

In Chapter 1, I hypothesize that there is a differential response by agents to changes in sovereign credit or default risk in both quiet (low default risk) and turbulent markets (high default risk). These market conditions create two different states of the market (world) or regimes. Investors and policy makers respond differently in the two regimes but the response in the turbulent market condition is amplified as policy makers attempt to smoothen the fluctuations and uncertainty while investors rebalance their portfolios in an attempt to hedge against downside risk of wealth loss. In the two regimes, the short run and long run dynamic relationships between any two cointegrated assets may change. To capture this phenomenon, this study tests for nonlinearities that may characterize the regimes, how cointegration relationships, short term dynamic interaction and price discovery (speed of adjustment to new information between two assets) may change in alternative regimes. To this end, I employ threshold cointegration, threshold vector error correction model (TVECM) asymmetrical return spillover modeling for sovereign credit default swaps (CDS), bonds and equity markets of seventeen emerging markets from four geographical regions. I find that there is non-linear cointegration and momentum in long-run adjustment process in 43/51 spreads analyzed. All countries analyzed have at least 2/6 possible regime specific asymmetric price discovery process. The study also finds evidence in support of asset substitution hypothesis and news-based hypothesis of financial contagions in sovereign CDS, bond and equity markets. The findings have important implications for asset allocation and portfolio rebalancing decisions by investors, policy intervention in financial markets, risk management and regime specific short and/or long term dynamic interactions among assets held in a portfolio as well as nonlinear speed of adjustment to new information. In chapter 2, I hypothesize that financial intermediaries can be categorized into bank-based institutions (BBIs) and market-based institutions (MBIs). MBIs and BBIs are under different regulatory agencies. Traditionally, only BBIs, regulated by the Fed, are used as conduits of transmitting liquidity and monetary policy into real economy and financial markets yet MBIs also play important role in providing liquidity and stability in financial markets. I use two tools of monetary policy (Federal fund rate and monetary aggregate) under two monetary policy regimes to investigate the impact of monetary policy under each regime on the liquidity of MBIs and BBIs. I investigate whether MBIs be used as conduits of transmitting monetary policy and liquidity in the market and if they should, under what economic and financial conditions (Regimes) should they be used. Moreover, what monetary policy tool is more effective for MBIs relative to BBIs under different regimes? Using Threshold vector auto-regressions and regime specific impulse response functions, I find that liquidity of BBIs and MBIs respond differently to different monetary policy tools under different regimes. Moreover, monetary policies are uncertain and vary over time. The Fed cannot continue to ignore MBIs in formulating and implementing monetary policy. Moreover, monetary aggregate policy is more effective when used on MBIs during contractionary monetary policy intervention (economic downturn) while Federal fund rate is more effective when used on BBIs under expansionary monetary policy.

This dissertation consists of two essays: the first investigates informed trading in the Chinese stock exchanges, and the second examines the persistency of correlation of currency future prices. For the first essay, using a sample of Chinese firms dual-listed in both the China mainland stock exchange and the Hong Kong stock exchange, I investigate the two types of informed trading - insider trading and trading derived from better analysis in the A-and H-share markets. The results suggest that H-shares have relatively more informed trading based on better analysis. In addition, the results from the firm size regression can also be seen as indirect evidence that larger firms tend to have trading with better analysis and less insider trading. These patterns are also confirmed in the sub-period analysis. However, I find no significant relation between informed trading and the relative pricing of A- and H-shares. For the second essay I examine the dynamic correlation between currency futures prices, focusing on the persistency of correlation of currency prices. Using the Dynamic Conditional Correlation model developed by Engle (2002), this study incorporates time-varying correlations into the analysis. The sample includes eight currency futures traded on the Chicago Mercantile Exchange from 1999 to 2008 and the U.S. dollar index future. The study finds that the Canadian dollar has the greater persistency while the Brazilian real has the weakest. No less important, the study finds that the time-varying conditional correlation between currency futures and the U.S. dollar futures is influenced by two types of liquidity: price impacts (Amihud illiquidity) and the logarithm of trading volume.

This dissertation consists of two essays: one looks at the time-varying relationship between earnings and price momentum, and the other looks at how liquidity and transparency affect the pricing differential between Chinese A-and Hong Kong H-share. The first essay presented in Chapter I investigates the time varying relationship between earnings momentum and price momentum. Using a Markov-switching framework, allowing for variation between high volatility and low volatility states, I find that price momentum is significantly more influenced by earnings momentum in the high volatility state. Further for price momentum I find that loser firms display a higher degree of differential response to earnings momentum across the low and high volatility states than winner firms. Limited financing and investor’s sensitivity to future investment opportunities might explain these two results. A further analysis indeed indicates that loser firms tend to be more financially constrained. Additionally, I investigate the relationship between investor sentiment and the two momentums and find that sentiment only has predictive power for price momentum profits in the low volatility state. Finally, the results are robust regardless of instrument variables. The second essay presented in Chapter 2 examines the impact of liquidity and transparency on the discount attached to H-shares from 2003 to 2011. The higher the relative illiquidity of an H-share, the more the H-share is discounted relative to the underlying A-share price. In addition, more actively traded A-shares and infrequently traded H-shares are associated with a higher H-share discount. Further, increases in the number of analysts following a firm, both in the A-and H- market, are accompanied by a lower H-share discount. Also, a firm with a higher percentage of A-share holdings by mutual funds is associated with a smaller H-share discount. Overall, the results provide support for the notion that liquidity and transparency affect the relative pricing of A- and H-shares.

The first essay examines the impact of investor protection, market monitoring, and liquidity on the firm-level and country-level earnings management using a sample of 432 firms from 34 countries cross-listed in the U.S. The major findings are as follows: First, cross-listed firms from countries with strong legal system, strong outside investor rights, more institutional investors, and higher financial transparency are less likely to engage in earnings management. In addition, in countries with strong investor protection or market monitoring, the level of earnings management is more pronounced for illiquid firms as compared to liquid firms. Second, cross-listed firms following IFRS have lower propensity in earnings management than those following the U.S. GAAP. Third, the degree of earnings management for cross-listed firms is greater in the home country than in the U.S. market. Fourth, cross-listed firms have higher earnings management in the pre-listing period than in the post-listing period. Fifth, foreign firms listed in U.S. major markets have lower propensity to engage in earnings management than those listed in the OTC market. The findings remain robust with the inclusion of industry fixed effects and GMM estimation. All findings are largely consistent with my hypotheses that better investor protection, greater market monitoring, and higher liquidity reduce the extent of earnings management. The second essay examines the relative contribution to price discovery process of EURO/USD currency futures traded on two major exchanges: Chicago Mercantile Exchange (CME) and Intercontinental Exchange (ICE), using the intraday data in 2010. The relative contribution to price discovery is estimated using the information share approach of Hasbrouck (1995). Empirical findings indicate that CME accounts for approximately 87% of price discovery in the EURO/USD market and its contribution is substantially larger in the morning than that in the afternoon. This study also examines the effect of trading characteristics, including volume, quoted bid-ask spread, and price volatility, on information share. CME’s price discovery leadership is attributed to its high trading activity, low transaction costs, and lower volatility. The results support the liquidity hypothesis that a market with greater liquidity contributes more to price discovery.

In the first chapter of this dissertation, I examine the relationship between hedging and diversification effects on CEO compensation in the Real Estate Investment Trust (REIT) industry. The REIT industry is suitable for this investigation for various reasons; primarily being that the REIT sample represents a relatively clean sample to study the effects of diversification and hedging on compensations. I find a positive and significant relationship between the interaction variable which reflects the effects of both hedging and diversification and CEO pay-for-performance sensitivity. This is consistent with the notion that managers are in a better position to manage firm risk if they use all the available tools and instruments, including hedging and diversification. I also find a positive and significant relationship between hedging and CEO pay-for-performance sensitivity, indicating that CEO compensation is more short term oriented because hedging is a relatively short term risk reduction strategy. The second chapter of this dissertation examines the relative contribution of regular and e-mini futures market to price discovery of EUR/USD futures contracts on the CME, using intraday data in 2010. The relative contribution to price discovery is estimated using the information share approach proposed by Hasbrouck (1995) and Gonzalo and Granger (1995). Empirical findings indicate that regular futures market accounts for approximately 66.5% of price discovery in the EURO/USD market. This study also examines if the regular future’s information share (IS) can be explained by the positioning of commercial and non-commercial traders. The results support the conclusion that the IS of regular futures can be better explained by non-commercial traders (speculators) than commercial traders (hedgers).

In the first chapter I investigate the change in operating performance, efficiency and value addition of US bank merger and acquisition after GLBA. I extend the previous research by combining all the previous methodology used in merger literature and added a new methodology namely Expected EVA improvement. I will test whether these performance metrics have similar results or the performance of merger vary depending on the measurements. I will also examine the factors that have significant impact on the change in the banks’ performance. My results show that industry-adjusted operating performance of merged banks increases significantly after a merger.I also find that the acquirer expected EVA improvement increase significantly after the merger. Revenue enhancement opportunity appears to be more profitable if there exist more opportunity for cost cutting such as geographic focus and diversified merger. Product diversification merger increase the industry adjusted performance more than product focused merger. The efficiency or profitability of targets has either positive or no effect change in acquirer performance. In the second chapter I examine how diversifying away from traditional lending activity into noninterest income has affected banks efficiency and value. Does this activity or product diversification affect the bank’s production efficiency and excess value? How does this efficiency translate into excess value for the firm or how excess value increase is related to diversification and efficiency? I find that diversifications significantly reduce the value of banks measured in excess value and vice versa regardless of which measures diversification or excess value I use. Both revenue and asset diversification also significantly reduce all measures of efficiency scores. But the impact of efficiency on diversification is mixed. Only efficiency scores computed based on variable return to scale have negative on revenue diversification and other efficiency scores have no impact on diversifications. I also find that increasing efficiency will increase the excess value of the banks significantly and vice versa. So increasing diversification will reduce the excess value and hence will lower the excess value or BHC with lower diversification will have lower excess value and are more efficient.

In the first chapter, I analyze the impact of changes in aggregate holding in special asset purchase programs by Federal Reserve Systems (FED) as an alternate monetary policy at aggregate level. Later, to complement the analysis of monetary impact at aggregate level, I also analyze the impact of monetary actions at bank stock level with a set of 186 banks. First, for the overall sample period, expected monetary shock has positive effect on bank stock return; however, unexpected shock component has otherwise negative impact. Second, during both conventional and QE regime, monetary shocks are not significant in explaining weekly stock returns; however change in FED’s total asset holding in special programs is significant during the QE regime and such findings are more robust for the “large” banks when compared to “medium” and “small” banks. The second chapter presents the second essay that is one of the early studies to analyze whether either the changes in accounting standard or the changes in prudential regulatory regimes may affect the bank earning management in terms of Loan Loss Provisioning (LLP) systematically. Results suggest that, in general, bank managers use LLP as a tool for earning management for income smoothing and also for capital management once LLP is allowed to be a part of Tier-I capital requirement. Both changes in prudential regulation from pro-cyclic to a dynamic regime and convergence of accounting standard from rule-based to principle-based standards have significant negative fixed effects separately and jointly once included.
