Simulated testing of nonparametric measure changes for hedging European options

We test the accuracy and hedging performance of the deltas given by a range of nonparametric measure changes. The nonparametric models accurately estimate deltas across a number of asset price dynamics. The optimal nonparametric measure change displays superior estimation bias, which depends on how the models capture the stylised features of the dynamics, moneyness, and time-to-expiry. Differences in estimation error appear negligible. The optimal measure change produces superior static hedging outcomes compared to the Black–Scholes model. Differences in dynamic hedging outcomes are negligible.     

Smith versus Friedman: Markets and ethics

This paper addresses the issue of ethics in modern business thought from the perspective of the father of modern economics Adam Smith using both An Inquiry Into the Nature and Causes of the Wealth of Nations and The Theory of Moral Sentiments. The foundation of modern business thought is represented by the Chicago/Austrian School of economic thought using Milton Friedman as a basis and examples from the popular business press and from the work of accounting scholars to illustrate the pervasiveness of this idea of market solutions to ethical problems.It is contended that modern business theory, as represented by this neoclassical economic paradigm, has established a moral code for business based on efficiency of outcome and the assumed link of efficiency to self-interested behavior. The result is markets as the arbitrators of ethical outcomes, and profit maximization as the ultimate moral code.
