We present a utility-based methodology for the valuation of early exercise contracts in incomplete markets. Incompleteness stems from nontraded assets on which the contracts are written. This methodology takes into account the individual’s attitude towards risk and yields nonlinear pricing rules. The early exercise indifference prices solve a quasilinear variational inequality with an obstacle ...

This paper considers a risk-based approach for indifference valuation of contingent claims in the context of a continuous-time stochastic volatility model. Since the market in the model is incomplete there is more than one arbitrage-free price of an option. We adopt a risk-based approach to select a seller’s and a buyer’s indifference price for the option contract. A convex risk measure is used...

We studied the interaction between rifampin and fusidic acid against a group of staphylococci. Of the 20 coagulase-positive strains studied, checkerboard studies revealed synergy in 3 and indifference in 17; time-kill studies revealed synergy in 18 of 19 coagulase-positive strains at both 24 and 48 h. Of the 19 coagulase-negative strains, checkerboard studies revealed synergy in 6 and indiffere...

Congenital indifference to pain is a rare and debilitating congenital disease. Individuals with the disorder may have one or a combination of sensory or autonomic deficits, which can range from lack of mechanical nociception, diminished ability to detect heat and cool stimulation, to the devastating and fatal form which includes autonomic dysfunction. It is important for radiologists to be able...

A selfish (SE) seller is a homo oeconomicus according to standard theory – she simply maximises her own material pay-off. Thus, since the pay-off of the customer does not affect the seller’s utility, the indifference curves of a SE seller in (ps, pc) space are vertical. An efficiency loving (EL) expert is willing to give up own monetary pay-off to increase the material pay-off of her trading pa...

The question of whether or not either elderly people or those whose life expectancy is short have commensurately reduced claims on their fellows, have, in short, fewer or less powerful rights than others, is of vital importance but is one that has seldom been adequately examined. Despite ringing proclamations of justice and equality for all, the fact is that most societies discriminate between ...

Abstract. Utility indifference pricing and hedging theory is presented, showing how it leads to linear or to non-linear pricing rules for contingent claims. Convex duality is first used to derive probabilistic representations for exponential utility-based prices, in a general setting with locally bounded semi-martingale price processes. The indifference price for a finite number of claims gives...
