We study the general problem of an agent wishing to minimize the risk of a position at a fixed date. The agent trades in a market with a risky asset, with incomplete information, proportional transaction costs, and possibly constraints on strategies. In particular, this framework includes the problems of hedging contingent claims and maximizing utility from wealth. We obtain a minimization prob...

A reductio ad absurdum takes the principles of a doctrine, applies them exactly as their creators did only to an entirely different subject and with horrendous results, and thus shows what absurd conclusions are logically compatible with the original thesis. The entire article applies the tenets of the Chicago law and economics tradition, as adumbrated by two of its most distinguished practitio...

It has long been an accepted precept that the purpose of management is the maximization of shareholder wealth. Few would dispute the notion that projects requiring long-term capital investments should be subjected to capital budgeting. Numerous authors have, however, questioned the appropriateness of subjecting non-capital expenditures, such as advertising, research or product development, to c...

We consider the problem of maximization of expected utility from terminal wealth for log and power utility functions in a market model that leads to purely discontinuous processes. We study this problem as a stochastic control problem both under complete as well as incomplete information. Our contribution consists in showing that the optimal strategy can be obtained by solving a system of equat...

We formulate conditions for the solvability of the problem of robust utility maximization from final wealth in continuous time financial markets, without assuming weak compactness of the densities of the uncertainty set, as customary in the literature. Relevant examples of such a situation typically arise when the uncertainty set is determined through moment constraints. Our approach is based o...

Firms that do better than their competitors in terms of satisfying customers, generate superior return at lower risk. Satisfied customers are more loyal, less sensitive to price movements. The aim of this study is to examine the impact of customer satisfaction on shareholders’ value creation. Customer satisfaction involves behavior of customers that typically relate to purchase or consumption o...
