Welfare Effects of Technological Convergence in Processed Food Industries
构建垄断竞争模型，分析国际技术趋同如何影响要素报酬、产出构成和福利，并用17个食品行业30国数据检验发现：技术趋同提升追随者相对工资和全球增加值份额，但福利效应取决于收入与贸易条件的相对强弱。
Abstract We develop a monopolistic competition model to investigate effects of international technological convergence on factor rewards, output composition, and welfare. Comparative static analysis indicates technological convergence improves the follower's—but impairs the leader's—international competitiveness. The leader's welfare improves unambiguously; the follower's welfare depends on the relative strength of convergence's income and terms‐of‐trade effects. We use data from seventeen food industries in thirty countries, 1993–2001, to test these analytical predictions. Evidence of convergence is found in thirteen of seventeen industries. Convergence lifts followers' relative wages and global value‐added shares. Followers benefit from convergence's positive income effect. Leaders benefit from higher terms of trade.
