摘要:We analyze the impacts of U.S. sanctions on Huawei smartphones on the Chinese smartphone market. The sanctions changed consumer sentiment toward domestic brands, substitution patterns across brands, and Huawei's production costs. Using quarterly data from 2016 to 2021, we estimate a random-coefficients demand model with a multi-product Bertrand pricing game of manufacturers. Our estimation reveals the following results. (1) The sanctions substantially increased consumer preferences for Huawei and other Chinese brands, shifting demand from foreign brands to Huawei and other Chinese brands. (2) The sanctions imposed a sharp supply shock on Huawei's 5G smartphone production. Counterfactual analysis reveals that, without the sanctions, consumer surplus inclusive of estimated sentiment utility would fall by $5.33 billion per quarter, because removing sanctions eliminates the positive consumer sentiment effect and changes equilibrium pricing by foreign brands.
