Domestic Support and Border Measures for Processed Horticultural Products
模拟政策改革对全球加工番茄市场的影响，发现降低加工番茄产品进口关税比减少欧盟国内支持更能影响市场并提升欧洲以外地区的福利。
Abstract In horticultural markets, trade barriers often apply to the processed products whereas domestic support applies to farm‐produced raw commodities. Here we assess the effects of such trade barriers and domestic support by simulating the effects of policy reform on global processing tomato markets, which are faced with modest processed product tariffs and high domestic support in the European Union (EU). Both protection and EU subsidy drive down world welfare, but we find that reducing import tariffs for tomato products would yield greater effects on markets and larger welfare impacts outside Europe than would reductions in EU domestic support.
