.6% increase in consumer demand attributable to the employment of a group buying mechanism. Through counterfactual analysis, we …

We propose a demand model where consumers simultaneously choose a few different goodsfrom a large menu of available … goods, and choose how much to consume of each good. Themodel nests multinomial discrete choice and continuous demand systems … purchasing different numbers of typesof goods. We show semiparametric identification of the model. We apply the model to …

Taking willingness to pay as model primitive, it … establishes a general and yet analytically simple demand function, and proposes an estimation procedure that uses survey to … solicit consumers' willingness to pay with which the underlying demand function can be consistently estimated using the …
