Tariff Pass‐Through and Welfare in the Tablet Computer Market*
利用美国平板电脑市场数据估计关税对价格和福利的短期影响，发现对中国组装企业征收25%关税导致其产品价格上升、利润下降，并产生显著的无谓损失。
This paper estimates short‐run effects of tariffs on United States tablet prices and welfare. Market data are used to estimate a model of demand and supply and to simulate prices and sales in scenarios with tariffs. A 25 per cent tariff on firms assembling in China results in tariff elasticity of tablet prices for taxed firms of 1.108, a 29.6 per cent decline in profits, and a deadweight loss of 28.8 per cent. Firms assembling elsewhere benefit from the reduction in rivals’ competitiveness. Long‐run implications are that firms may decide to shift production from ‘uncompetitive’ facilities in China to countries that are politically favored.
