Pricing and hedging of Asian options: Quasi-explicit solutions via Malliavin calculus

We use Malliavin calculus and the Clark-Ocone formula to derive the hedging strategy of an arithmetic Asian Call option in general terms. Furthermore we derive an expression for the density of the integral over time of a geometric Brownian motion, which allows us to express hedging strategy and price of the Asian option as an analytic expression. Numerical computations which are based on this expression are provided

Narcissus enters the courtroom: CEO Narcissism and fraud

This study explores the aspects of the relationship between possible indicators of CEO narcissism and fraud. Highly narcissistic CEOs undertake challenging or bold actions to obtain frequent praise and admiration. The pursuit of narcissistic supply may result in a stronger likelihood of a CEO to undertake bold actions with potential detrimental consequences for the organization. The sample consists of all S&P 500 CEOs from 1992 till 2008 with more than 3 years of tenure. The measurement of CEO narcissism is based on 15 objective indicators and fits the main conceptualization of narcissism. This data collection provides a score for all S&P 500 CEOs according to their narcissistic tendencies.

The findings confirm the expected influence of plausible proxies for CEO narcissism on fraud by showing a positive relationship. This confirms the psychologic perspective of CEO narcissism as a potential cause of fraud
