Does the Company Lawyer Have Your Back? A Brief Look at the Need for Personal Private Liability Insurance

There are four traditional uses of private personal liability insurance dating from the 1970s to the present (Hayes 1979; Sommers 2005) which pertain either to individuals or corporations. There is insurance to cover damage to rental cars, umbrella insurance to cover any injury to a guest at one’s home, insurance bought by corporations to cover potential corporate responsibility for actions of company representatives and insurance including misadventures with financial information and morally hazardous behavior as well as corporate required actions which are later deemed to be wrong or inappropriate. Employees need to find out if the employee manual provides for coverage for legal liabilities resulting out of performing job responsibilities. Due to a need to reduce company costs, many companies are reducing or eliminating coverage for employees for many types of actions. Private personal liability insurance gives you the peace of mind to know what you are covered for and for how long. Employee rights versus corporate budgets are at the core of this discussion.

基于实物期权方法的并购中目标企业价值评估

本文利用实物期权方法研究并购中目标企业的价值评估模型，认为并购中目标企业的价值不仅包括目标企业自身的价值，还应包括由于并购的实物期权特征和协同效应产生的目标企业相对于并购企业的附加价值。目标企业自身的价值由传统的折现现金流法计算，并通过实物期权理论调整。并购附加价值分别由实物期权理论方法、由改进的折现现金流法和专家打分法计算和分配。

Risk-taking incentives of executive stock options and the asset substitution problem

Various theoretical models show that managerial compensation schemes can reduce the distortionary effects of financial leverage. There is mixed evidence as to whether highly levered firms offer less stock‐based compensation, a common prediction of such models. Both the theoretical and empirical research, however, have overlooked the leverage provided by executive stock options. In principle, adjusting the exercise prices of executive stock options can mitigate the risk incentive effects of financial leverage. We show that the near‐universal practice of setting option exercise prices near the prevailing stock price at the date of grant effectively undoes most of the effects of financial leverage. In a large cross‐sectional sample of Canadian option‐granting firms, we find evidence that executives' incentives to take equity risk are negatively rather than positively related to the leverage of their employers.     

Frictions, Heterogeneity and Optimality in Mortgage Modeling

The purpose of this article is to provide a unified framework for incorporating frictions into a theoretical options-pricing model (OPM) for mortgages. This article presents formulation for a frictions-adjustable mortgage model that integrates borrower heterogeneity while simultaneously preserving prepayment and default financial decisions. Our model demonstrates the flexibility of the OPM by simulating separate and concurrent effects of three categories of frictions on the mortgage and mortgage components. Researchers can use our example formulation to determine the effects of specific borrower characteristics on mortgage values without destroying the options theoretic framework.     

Valuation of commodity derivatives in a new multi-factor model

This paper extends existing commodity valuation models to allow for stochastic volatility and simultaneous jumps in the spot price and spot volatility. Closed-form valuation formulas for forwards, futures, futures options, geometric Asian options and commodity-linked bonds are obtained using the Heston (1993) and Bakshi and Madan (2000) methodology. Stochastic volatility and jumps do not affect the futures price at a given point in time. However, numerical examples indicate that they play important roles in pricing options on futures. This revised version was published online in June 2006 with corrections to the Cover Date.     

Implied Volatility of Interest Rate Options: An Empirical Investigation of the Market Model

We analyze the empirical properties of the volatilityimplied in options on the 13-week US Treasury bill rate. These options havenot been studied previously. It is shown that a European style put optionon the interest rate is equivalent to a call option on a zero-coupon bond.We apply the LIBOR market model and conduct a battery of validity tests tocompare three different volatility specifications: contact, affine, and exponentialvolatility. It appears that the additional parameter in the affine and theexponential volatility function is not justified. Overall, the LIBOR marketmodel fares well in describing these options.
