In this paper we state and prove some new results about the optimal boundaries. These boundaries (also called Pareto boundaries or efficiency boundaries or maximal/minimal boundaries) are of increasing importance in the applications to Decision Theory and Economics. First of all the Pareto...

This paper investigates a simple risk management problem where an investor is forced to hold a risky asset and then allowed to trade put options on the asset. I simulate the distribution of returns for different quantities of options and investigate statistics from the distribution. In the first...

Confidence sets based on sparse estimators are shown to be large compared to more standard confidence sets, demonstrating that sparsity of an estimator comes at a substantial price in terms of the quality of the estimator. The results are set in a general parametric or semiparametric framework.
