The major objectives of health policy reform include efficiency, equity, quality improvement and need of insurer¡¦s health services . For those goal ,the capitation payment is used . The result of insurer¡¦s privilege may be victimized if the competitive health insurance market has not any norm, So some nations have already introduced risk adjustment to their health care reform, because risk adjustment may achieve both goal of equity and efficiency . This study is using 3 years medical expenditure of a isolated area as analysis unit, data duration from 2000 to 2003. the purpose of study intends to develop a risk-adjusted capitation rates using demographic ¡Bcatastrophic factor and prior utilization factors. The results show the model with only age and gender factor has R2 5.69%¡BAdj-R2 5.65%. On the other hand, the model accommodating catastrophic factor has R2 11.71%¡BAdj-R2 11.67%¡Athe model accommodating 1~2 year prior utilization has R2 43.14%¡B45.57%¡BAdj-R243.11%¡B45.54%¡C

This paper investigates whether the potential for rent extraction due to shareholders' strategic actions is reflected ex ante in stock and bond prices based on a joint study of stock and bond markets. I document that higher default probabilities are associated with higher yield spreads and bond returns but not with higher stock returns. Shareholder advantage has no significant effect on distress risk premia in stock or bond returns for firms with bonds outstanding. I also find that the negative relationship between distress risk and stock returns is more evident for firms with high trading cost and arbitrage risk. My findings suggest that the stock market, but not the bond market, misprices distress risk.

What is the measure of the effectiveness of corporate governance? What is the relationship between corporate governance and performance? This thesis sheds light on these questions by examining the consequences of two kinds of corporate governance monitoring mechanisms, religion as an external mechanism and independent directors as an internal mechanism. Though recent work in finance and accounting provide evidence that religion is an effective external monitoring mechanism, whether it has pricing effects has yet to be examined. I explore this issue by investigating the relation between the degree of religiosity surrounding a firm’s headquarters and the firm’s cost of equity capital in Chapter 2. I find that firms located in more religious counties of the U.S. exhibit a lower cost of equity capital. The effects are also more pronounced for firms and during periods lacking alternative regulation mechanisms. Finally, I find that the effects of religion on the firm’s cost of equity capital are more pronounced for firms with greater information asymmetry. The second part of my thesis is motivated by the considerable debate on whether board independence is an effective internal monitoring mechanism. I offer a new perspective by examining the relationship between firm risk and board independence. I find that board independence is associated with a significantly lower level of idiosyncratic risk. Further tests suggest that firms’ idiosyncratic risk is negatively related to the independence of audit committees and nominating committees, but positively related to the independence of compensation committees. In addition, I find that firms with greater board independence display lower degrees of operating risk exposure, and are less prone to stock price crashes. My thesis makes several important contributions to the literature. First, my thesis shows that studying the important social factors that influence different agents and determine the deeds of collective groups may be important for corporate governance research and practice. Furthermore, my results provide robust evidence supporting the view that religion facilitates economic development. Finally, my findings provide an explanation for the insignificant relationship between board independence and firm performance documented by recent literature. / Thesis (Ph.D, Management) -- Queen's University, 2011-07-29 10:45:05.376
