TRADE POLICY AND MARKET POWER: FIRM‐LEVEL EVIDENCE
利用新数据和识别策略，发现非关税措施会增强存续企业的市场势力，而关税则通过租金转移效应削弱外国企业的市场势力。
Abstract This article identifies the effect of trade policy on market power through new data and a new identification strategy. We identify market power by observing how exporting firms price discriminate across markets following variations in bilateral exchange rates. Pricing‐to‐market is prevalent in all countries in our sample, even among small firms, although it is increasing in firm size. More importantly, we find that the effect of nontariff measures (NTMs) is not isomorphic to that of tariffs. Whereas tariffs reduce the market power of foreign firms through rent‐shifting effects, NTMs reinforce the market power of nonexiting firms, domestic and foreign alike.
