演講摘要 : I present a game-theoretical model to empirically analyze the consumption interactions among household members. Although multiple Nash equilibria of consumption decisions may exist in a household, model parameters are pointwise identified for households with only two members. I propose a semiparametric maximum likelihood estimator and apply it to study the subscription decision for cellular phone service in Taiwan. On average, a consumer’s probability of subscribing to cellular service rises 35 percentage points when the other household member chooses to subscribe, suggesting the existence of intra-household network effects. Moreover, intra-household effect is heterogeneous among households, which increases in household income, but decreases in the number of children and the age difference in a household.
