Impact of global value chains on tariffs and non-tariff measures in agriculture and food
研究了全球价值链参与如何通过影响游说和政府激励来降低农业和食品部门的贸易壁垒，发现价值链整合与关税降低相关，尤其在区域贸易协定之外，且与非关税措施降低相关。
We analyse whether global value chains (GVCs) reduce trade barriers in the agricultural and food sectors as they affect lobbying and government incentives. Political economy theory predicts that tariffs will be lower in countries integrated in GVCs and that the effect will be stronger outside regional trade agreements (RTAs). We use data from 1995 to 2015 from 160 countries on tariffs and non-tariff measures (NTMs) in the agri-food sector. Our evidence indicates that GVC integration, measured as domestic (foreign) value added in foreign (domestic) final goods, does affect trade policy. Stronger GVC integration is associated with lower tariffs, but mainly outside RTAs, and lower NTMs, both inside and outside RTAs.
