An example of indifference prices under exponential preferences
نویسندگان
چکیده
The aim herein is to analyze utility-based prices and hedging strategies. The analysis is based on an explicitly solved example of a European claim written on a nontraded asset, in a model where risk preferences are exponential, and the traded and nontraded asset are diffusion processes with, respectively, lognormal and arbitrary dynamics. Our results show that a nonlinear pricing rule emerges with certainty equivalent characteristics, yielding the price as a nonlinear expectation of the derivative’s payoff under the appropriate pricing measure. The latter is a martingale measure that minimizes its relative to the historical measure entropy.

Time-consistency of indifference prices and monetary utility functions∗
We consider an economic agent with dynamic preference over a set of uncertain monetary payoffs. We assume that the agent’s preferences are given by utility functions, which are updated in a time-consistent way as more information is becoming available. Our main result is that the agent’s indifference prices are time-consistent if and only if his preferences can be represented with utility funct...

We consider risk-aware forest owners and electricity producers evaluating the Reduced Emissions from Deforestation and Degradation (REDD)-based offsets with a benefitsharing mechanisms under uncertain CO2 prices. For a range of CO2 prices and respective risks perceived by the forest owner (seller) and electricity producer (buyer), we apply a model of fair (indifference) pricing. Parties’ risk p...

متن کاملApproximate Solutions for Indifference Pricing under General Utility Functions
With the aid of Taylor-based approximations, this paper presents results for pricing insurance contracts by using indifference pricing under general utility functions. We discuss the connection between the resulting “theoretical” indifference prices and the pricing rule-of-thumb that practitioners use: Best Estimate plus a “Market Value Margin”. Furthermore, we compare our approximations with k...
متن کاملExponential utility indifference valuation in a general semimartingale model
We study the exponential utility indifference valuation of a contingent claim H when asset prices are given by a general semimartingale S. Under mild assumptions on H and S, we prove that a no-arbitrage type condition is fulfilled if and only if H has a certain representation. In this case, the indifference value can be written in terms of processes from that representation, which is useful in ...
