PUR 6403 Crisis and Risk Management focuses on practical applications of theory and research to identify and strategically manage issues and operational risks that can materially affect the continuity of global organizations. Emphasis is placed on preparing managers for ethical and effective risk and crisis communication, as well as the formulation of strategic crisis communication plans. Class information: PUR 6403 §1219 meets 8th-10th periods (3-6 p.m.) on Thursdays in Weimer 3020. Course goals: The goal of PUR 6403 is for students to understand and appreciate how issues impact organizational continuity, how issues and operational risks are strategically managed and crises averted, and the importance of ethical, effective risk and crisis communication.

Compensation planning within firms creates important corporate financial problems. Theoretical models and empirical tests of hypotheses in this area should play a much larger role than currently in the modern theory of corporate finance. Employees fund a large proportion of their firm's activities through deferred compensation arrangements tied to the performance of their company. These arrangements are generally put in place for incentive reasons, to align the interests of employees more closely with those of shareholders. Moreover, tax rules encourage or discourage these arrangements at various times. Currently, both tax rules and incentive considerations encourage stock buyback programs to fund deferred compensation arrangements. Prior to the 1980s, however, tax rules favored funding in other than company stock, implying that employees likely held company stock for incentive and not for tax reasons during this time period.

Nonsynchronous trading of securities introduces into the market model a potentially serious econometric problem of errors in variables. In this paper properties of the observed market model and associated ordinary least squares estimators are developed in detail. In addition, computationally convenient, consistent estimators for parameters of the market model are calculated and then applied to daily returns of securities listed in the NYSE and ASE.

This paper suggests that it is not possible to demonstrate, using the best available empirical methods, that the expected returns on high yield common stocks differ from the expected returns on low yield common stocks either before or after taxes. A taxable investor who concentrates his portfolio in low yield securities cannot tell from the data whether he is increasing or decreasing his expected after-tax return by so doing. A tax exempt investor who concentrates his portfolio in high yield securities cannot tell from the data whether he is increasing or decreasing his expected return. We argue that the best method for testing the effects of dividend policy on stock prices is to test the effects of dividend yield on stock returns. Thus the fact that we cannot tell, using the best available methods, what effects dividend yield has on stock returns implies that we cannot tell what effect, if any, a change in dividend policy will have on a corporation's stock price.
