Essays in nonparametric measures of changes in taste and hedging behavior with options
This dissertation consists of three self contained essays. The first develops and implements a method for measuring taste change that does not require any parametric estimation. The second essay shows how expected utility maximization problems can be solved when the distribution of prices or revenue is truncated. The third essay examines optimal hedging behavior of a firm faced with both price and output uncertainty, and who has access to both futures and options markets.
