| Abstract: | The double-hurdle and infrequency-of-purchase models are generalized with the inverse hyperbolic sine transformation in the dependent variable. The resulting specifications feature more flexible parameterization and error distributions than the untransformed models. Using the 1987-88 Nationwide Food Consumption Survey data on household pork consumption, a nonnested test suggests that the IHS double-hurdle model provides better characterization of the data-generating process than the IHS infrequency-of-purchase model but the elasticities derived from these models are similar. |
