Benchmark two-good utility functions involving a good with zero income elasticity and unit income elasticity are well … known. This paper derives utility functions for the additional benchmark cases where one good has zero cross …-price elasticity, unit own-price elasticity, and zero own price elasticity. It is shown how each of these utility functions arises from …
