In this paper, we analyze the impact of handset subsidies on demand for bundles of mobile telecommunications service and handsets and evaluate the effects of subsidies and bundling regulations on social welfare using a counterfactual simulation analysis. By estimating a structural model that explicitly considers the demand for bundles and the profit maximization of mobile operators and handset manufacturers separately, we find that mobile carriers indeed offer a discriminatory subsidy for handsets depending on a consumers’ choice of service plans. Results of the simulation show that the ban of or putting a ceiling on handset subsidies reduces social welfare because, as the handset subsidy is regulated, consumers have to pay more for handsets or give up purchasing new products and service, and profits of providers are also reduced due to the decrease in demand. If the bundling of mobile carriers is prohibited, then price competition between handset manufacturers occurs, but the social welfare will not improve because the competition will not reduce handset prices as much as the price with the current subsidy level. Thus, in this paper, we argue that the most effective way to improve social welfare is to let the market decide.
