For any utility function with asymptotic elasticity equal to one, we construct a market model in countable discrete time, such that the utility maximization problem with proportional transaction costs admits no solution. This proves that the necessity of the reasonable asymptotic elasticity condition, established by Kramkov and Schachermayer [KS99] in the frictionless case, remains also valid in the presence of transaction costs.

Abstract
For any utility function with asymptotic elasticity equal to one, we construct a market model in countable discrete time, such that the utility maximization problem with proportional transaction costs admits no solution. This proves that the necessity of the reasonable asymptotic elasticity condition, established by Kramkov and Schachermayer [KS99] in the frictionless case, remains also valid in the presence of transaction costs.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
