This paper deals with the effects of tax rate uncertaity on risk-neutral and risk-averse investment behavior. We analyse effects of stochastic tax rates on both real and financial investment. It emerges that under risk neutrality as well as under risk aversion, increased tax rate uncertainty has...

We consider the demand for state contingent claims in the presence of a zero-mean, nonhedgeable background risk. An agent is defined to be generalized risk averse if he/she reacts to an increase in background risk by choosing a demand function for contingent claims with a smaller slope. We show...

In the paper we present the application of risk neutral measure estimation in the analysis of the index WIG20 from Polish stock market. The risk neutral measure is calculated from the process of the options on that index. We assume that risk neutral measure is the mixture of lognormal...
