We here suggest to consider Lévy processes transformed by monotonous functions, which allow to overcome this restriction and provides a new state-dependent wear model. These transformed Lévy processes are first observed to remain tractable Markov processes. Some distributional properties are derived. The impact of the current state on the future increment level and on the overall accumulated level is investigated from a stochastic monotonicity point of view. Positive dependence properties and stochastic monotonicity of increments are also studied.

The exponential utility function is a special utility function and relevant when the associated investor is risk averse as well as risk loving. The index based on the utility indifference price with the exponential utility function becomes an index for the random variable g of gambles with the property E [ g ] > 0 and P ( g 0 ) > 0 when the investor is risk averse and an index for the random variable g of gambles with the property E [ g ] 0 and P ( g > 0 ) > 0 when the investor is risk loving. We provide sufficient conditions for the existence and uniqueness of the index when the investor is risk averse and risk loving.
