Pro-competitive Effect of Trade and Non-decreasing Price-Cost Margins
研究了1970-2003年OECD国家贸易对价格成本加成的影响，发现进口平均使加成下降5个百分点，但金融深化和反通胀部分抵消了这一效应。
This study surveys the empirical evidence on the pro-competitive effect of international trade and analyses the determinants of price-cost margins for OECD countries between 1970 and 2003. The main objective was to focus on the quantification of the impact of imports on margins, and understand why, despite trade liberalization, price-cost margins have not fallen overall. On average, imports would have contributed to a large decrease of five percentage points in the price-cost margins. However, these effects seem to have been partially counterbalanced by the impacts of financial deepening and disinflation.
