First and Second Degree Transformations and Comparative Statics under Uncertainty
The purpose of this paper is to investigate the direction of change in the optimal value of the choice variable following a deterministic transformation of the underlying random variable. Here, the author considers transformations representing either first or second degree stochastically dominant shifts. Several theorems are presented giving conditions on the economic model and risk-taking characteristics of the decisionmaker that are sufficient to obtain unambiguous comparative statics results for arbitrary first degree stochastically dominant and second degree stochastically dominant transformations as well as for simple first degree stochastically dominant and second degree stochastically dominant transformations.
