This study explores two issues, one is to investigate the determinants of net interest margins and bank risk-taking from 1993 to 2001 in a partial universal banking system, taking Taiwan as our example, and the other is to provide some empirical evidences of exchange ratio determination of bank mergers in Taiwan. In the first topic, the partial universal banking system here is a mix of the conventional commercial banking system (whose activity is mainly loan-deposit taking) and the universal banking system (engaging in both loan-deposit and investment activities). We employ the recently developed method of the panel data threshold regression method to estimate the determinant function of the net interest margin and bank risk-taking model. It is found that the corporate governance plays an important role in explaining the recent behavior of the banking industry. The empirical results show that the net interest margins in the commercial banking system are affected by credit risk, interest rate risk, the degree of leverage and management quality, unlike the net interest margins in the universal banking system which are more sensitive to only-credit risk and the degree of leverage. Moreover, the relationship between managerial ownership and credit risk taking behavior is inverse U-shape in the commercial banking system, consistent with the corporate control hypothesis, unlike U-shape relation in the universal banking system that supports moral-hazard hypothesis. In the second topic, we not only extend Larson and Gonedes (1969) merger exchange ratio model to taking account of market risk and more participants but also apply Marsh-Merton dividend behavior reduced form (1987) to estimate the expected post-merger price-earnings ratio. Taking the first case of the bank merger according to the Financial Institution Merger Law as our sample, we find that the L-G model indicates the interval of exchange ratios that enhance, or at least not cause any diminution in the wealth positions of all parties to a proposed bank merger. Also, the bargaining area offers some information to help merger candidates to negotiate final actual exchange ratio.

To achieve the goal of universal coverage of health insurance for the Americans, in March 2010, the Patient Protection and Affordable Care Act (ACA) was signed into law. The ACA targets at providing help to improve access to affordable health coverage for everyone and protect consumers from abusive insurance company practices. One of the precedent mandates, implemented in September 2010, is to expand coverage on young adults of age 19 to 26, who may lose insurance coverage due to the remove from their parents’ plan after age 18 and lacking of productivity to bargain with employers in the labor market. This dissertation looks into the impact of the ACA health insurance coverage expansion for young adults on the subsequent health outcomes, health care utilization, and further social impact on traffic fatalities. Difference-in-differences models are used with different treatment groups and corresponding control groups. Chapter I uses survey data (BRFSS) to evaluate health care access, health behavior and self-assessed health status. The results suggest an improvement in health care access and self-assessed health but more risky behavior. Chapter II uses hospital discharge data (NIS) to estimate avoidable hospitalization in order to assess primary care utilization. The result shows that less primary care was consumed, which leads to more avoidable hospitalization but health may have been improved by using more hospital care. The results from both chapters imply potential ex ante moral hazard among young adults in the policy targeting age group. Thus, chapter III uses accident records data (FARS) to examine the impact of the health insurance expansion on traffic fatality for young adults, to see whether young drivers perform ex ante moral hazard through risky behavior like drunk and/or reckless driving after they get covered by the health insurance expansion policy. Primary result shows that there is an increase in traffic accidents and fatalities for those younger adults as a result of the ACA dependent coverage expansion.

Many venture capitalists (VCs) use the “VC method” of valuation where they use judgment to estimate a probability of successful exit while determining the ownership share to demand in exchange for investing in a venture. However, prior models are not aligned with the “VC method” because they do not consider private information about entrepreneurial characteristics, the primary drivers of the above probability, and consequently do not model judgment. The three main chapters of this thesis—one theoretical, one simulation, and one empirical study—examine the venture capital deal process in sync with the “VC method.” Chapter 2 is theoretical and develops a principal-agent model of venture capital deal process incorporating double-sided moral hazard and one-sided private information. The VC is never fully informed about the entrepreneur’s disutility of effort in spite of due diligence checks, so takes on a belief about the latter’s performance in the funded venture to determine the offer. This study suggests that there exists a critical point in the VC’s belief—and correspondingly in the VC’s ownership share—that maximizes the total return to the two parties. It also uncovers optimal revision strategies for the VC to adopt if the offer is rejected where it is shown that the VC should develop a strong advisory capacity and minimize time constraints to facilitate investment. Chapter 3 simulates venture capital deals as per the theoretical model and confirms the existence of critical points in the VC’s belief and ownership share that maximize the returns to the two parties and their total return. Particularly, the VC’s return (in excess of his or her return from an alternate investment) peaks for a moderate ownership share for the VC. Since private information with the entrepreneur would preclude the VC from knowing these critical points a priori, the VC should demand a moderate ownership share to stay close to such a peak. Using data from simulations, we also generate predictions about the properties of the venture capital deal space—notably: (a) Teamwork is crucial to financing; and (b) If the VC is highly confident about the entrepreneur’s performance, it would work to the latter’s advantage. Chapter 4 reports the results from our survey of eight seasoned VCs affiliated with seven firms operating in Canada, USA, and UK, where our findings received a high degree of support.

A pesquisa traz uma crítica à teoria moderna de finanças em relação à política de gestão de risco, especificamente sobre o Value at Risk, e como ela afeta o risco na economia. O trabalho propõe uma discussão comportamental da ineficácia do VaR e como este tipo de informação pode ser ruim para a economia, por refletir no problema do moral hazard (risco moral) para os gestores, baseados na ilusão de compreensão, ilusão de validade e de habilidade. A dissertação conclui que,ao superestimar a informação do VaR, os agentes alteram seu comportamento para tomar decisão e, com este risco moral, podem gerar o problema dos black swans (cisnes negros). / The research brings a critique of modern finance theory in relation to risk management policy, specifically on the Value at Risk, and how this affects the risk in the economy. The paper proposes a behavioral discussion of VaR ineffectiveness and how such information may be bad in the economy, for reflecting on the moral hazard problem for managers, based on the illusion of understanding, illusion of validity and ability. The dissertation concludes that, to overestimate VaR information, the agents change their behavior to take this decision and, this moral hazard, can generate the black swans.

One of the main purposes of a Regulatory Agency is to monitor the quality of the service that regulated companies provide to its final users, in order to achieve an improvement in its performance and verify compliance with minimum quality standards that legislation impose on the concessionaires of public services.Given the asymmetry of information that tends to exist between the companies providing public services and the regulator, the decision by the latter allows them to reduce the costs that must be incurred to provide a service with appropriate quality standards, in order to maximize their benefits; and prevents the regulator to oversee such a service and take necessary corrective actions for the population. This conflict of interest is known as moral hazard.This article identifies and describes the situations in which moral hazard can occur, proposing the use of incentives to resolve the conflict. / Una de las funciones de un organismo regulador es la supervisión de la calidad del servicio que las empresas reguladas prestan a los usuarios finales, con el objeto de lograr una mejora en su prestación y verificar el cumplimiento de los estándares de calidad mínimos que la legislación de la materia impone a las concesionarias de dichos servicios públicos.Dada la asimetría de información que tiende a existir entre las empresas prestadoras de servicios públicos y el regulador, la toma de decisiones por parte de éstas les permite disminuir los costos en que deben incurrir para prestar un servicio con estándares de calidad adecuados, a efectos de maximizar sus beneficios; e impide que el regulador pueda fiscalizar tal servicio y tomar las acciones correctivas necesarias en favor de la población. Este conflicto de intereses es conocido como riesgo moral. El presente artículo identifica y describe las situaciones en las que puede presentarse riesgo moral, proponiendo la utilización de incentivos para solucionar dicho conflicto.
