标题：Identification of Consumer Segments and Its Implication on the Willingness-to-Pay Distribution: The Case of Demand for Non-Genetically Modified Vegetable Oil in the United States

We find evidence that those who prefer non-GM have a different marginal utility of income and that naïve pooling of consumer segments may yield a misleading recommendation for both agribusinesses and policy makers.
