A mutual insurance diffusion stochastic control problem

This paper determines the optimal loading factor policy of a mutual insurance firm. Insurance is viewed as a collective process of N persons paying fixed (or variable, contingent) premiums and seeking protection against claims. Risk reduction for each person is then exercised through a distribution of risk by aggregating individual risks and by accumulating cash (net of operating expenses) to meet possible contingent claims. By assuming an approximate claims diffusion process, stochastic control problems for selecting the optimum loading factor policies are stated and resolved analytically. In particular, the implicit cost of bankruptcy is computed and an optimum variable-feedback loading policy is established.     

Attention Deficit/Hyperactivity Disorder in the Workplace Under the ADA in the Wake of Sutton and Its Companions

The terms Attention Deficit Disorder (ADD) or Attention Deficit/Hyperactivity Disorder (AD/HD) refer to a neurological impairment that affects the individual's ability to sustain attention and to behave in a calm, rational manner.³Although this disorder has long been considered to be restricted to childhood, recent research has demonstrated that many children carry it over into adult life and take it with them into the workplace. Most U.S. courts have treated AD/HD as a disability covered by the Americans with Disabilities Act (ADA).⁴However, in the summer of 1999, the U.S. Supreme Court made three decisions that will undoubtedly affect the future status of AD/HD and other impairments under the ADA. This article examines those decisions, how they affect the employment rights of AD/HD-afflicted employees, and the changes they will probably bring to litigation in this area. Because we have many reservations about the court's decisions, we not only voice our criticisms of the decisions, but also offer an alternative approach.     

Profiting from government stakes in a command economy: Evidence from Chinese asset sales

We examine the market response to an unexpected announcement of the sale of government-owned shares in China. In contrast to earlier work, we find a negative effect of government ownership on returns at the announcement date and a symmetric positive effect from the policy's cancellation. We suggest that this results from the absence of a Chinese political transition to accompany economic reforms, so that the benefits of political ties outweigh the efficiency costs of government shareholdings. Companies managed by former government officials have positive abnormal returns, suggesting that personal ties can substitute for government ownership as a source of connections.     

The S&P500 index effect reconsidered: Evidence from overnight and intraday stock price performance and volume

This study focuses on S&P500 inclusions and deletions, examining the impact of potential overnight price adjustment after the announcement of an S&P500 index change. We find evidence of a significant overnight price change that diminishes the returns available to speculators although there are still profits available from the first day after announcement until a few days after the actual event. More importantly, observing the tick-by-tick stock price performance and volume effects on the key days during the event window for the first time, we find evidence of consistent trading patterns during trading hours. A separate analysis of NASDAQ and NYSE listed stocks allows for a detailed examination of the price and volume effect at an intra-day level. We find that index funds appear to cluster their rebalancing activities near to and after the close on the event date, suggesting that they are more concerned with tracking error than profit.     

The information content of option-implied volatility for credit default swap valuation

Credit default swaps (CDS) are similar to out-of-the-money put options in that both offer a low cost and effective protection against downside risk. This study investigates whether put option-implied volatility is an important determinant of CDS spreads. Using a large sample of firms with both CDS and options data, we find that individual firms’ put option-implied volatility dominates historical volatility in explaining the time-series variation in CDS spreads. To understand this result, we show that implied volatility is a more efficient forecast for future realized volatility than historical volatility. More importantly, the volatility risk premium embedded in option prices covaries with the CDS spread. These findings complement existing empirical evidence based on market-level data.     

Convertible Securities and Bankruptcy Reforms: Addressing Too Big to Fail and Reducing the Fragility of the Financial System*

Eliminating too big to fail should be the first priority of any regulatory reform. But this is easier said than done. As the crisis has taught us, when the systemic risks are perceived to be large, regulators will be very reluctant to close down insolvent firms or impose losses on creditors. So how do we reduce these risks so that regulators can credibly commit to a policy of allowing financial companies to fail and not resort to rescues or bailouts? The author proposes two complementary approaches to this problem: The first is to design capital structures with corrective mechanisms that kick in when a financial firm displays signs of trouble, but still has positive economic capital. To this end, the author endorses the Squam Lake Report's proposal that encourages financial firms to issue convertible debt with an “automatic” provision for converting to equity. In contrast to the Squam Lake proposal, however, the author argues that the conversion to equity should not depend on regulators' decisions and should take place before individual banks and the financial system are in full crisis mode. The second approach is to design a resolution mechanism that will close failing financial firms when early intervention has not led to the firm's recovery. The author argues that the best model for this mechanism is bankruptcy, because of its resolution of claims according to predetermined rules rather than regulatory discretion. However, certain forms of early intervention can also help to lower the costs of permitting firms to fail. For example, the Squam Lake idea that financial institutions be required to develop living wills should make it easier to unwind these firms in an orderly fashion and provide regulators with insight into the degree of systemic risk that these firms impose. The author notes that the challenges associated with getting the executives of healthy banks to plan for their own bankruptcy may indicate that a better use of regulatory resources might be to view the living will as one of the tools of prompt corrective action for firms that become undercapitalized but are still solvent. Once a firm has been declared undercapitalized, regulators would have greater bargaining power to insist on a serious plan for bankruptcy.     

An investigation of the giving behavior of loyal,lapsed, and non‐givers to a religious organization

• This paper provides a comparative study of the giving behavior of current donors (CDs), lapsed donors (LDs), and non‐donors (NDs) in a Catholic diocese in New England. Focus groups were conducted and surveys were administered to Catholics to compare the attitudes and behaviors of lapsed and active donors as well as those who had not given to a recent diocesan annual campaign. The results show significant differences between the groups. Active donors indicate a much greater level of satisfaction with the church, are more aware of its programs, and feel they are more recognized for their gifts than do lapsed or NDs. These findings suggest that relationship fundraising, and creating trust, are critical to forging and maintaining valued donor relationships. The program implemented by the diocese as a result of the study is described.

ECONOMIC SANCTIONS REVISITED: ADDITIONAL INSIGHTS INTO WHY THEY FAIL

Economic sanctions have a poor track record in achieving their objectives. In most cases, they are ineffective in bringing about policy change, cause increased suffering in the sanctioned country and reduce opportunities for business. This paper provides additional insights into why sanctions fail by examining two overlooked factors: power–dependency theory and pressure for political stability.
