Contagion Through Interactive Production and Dynamic Effects of Trade
构建了一个两国模型，其中学习通过互动生产产生，内生化了国际技术溢出的发生，从而整合了内生增长的收敛与发散文献；它修正了“落后的优势”概念，指出技术差距过大会减少跨国溢出；并指出贸易除了已知的“传染效应”外，还通过“互补效应”促进欠发达国家的技术进步，将其资源转向更复杂的中间产品生产。
This paper produces three main results in a two‐country model where learning is generated through interactive production. First, it endogenizes the incidence of international spillovers and consequently, integrates the convergence and divergence literature of endogenous growth. Second, it qualifies the notion of ‘the advantage of backwardness’ and shows that a large technology gap may reduce cross‐country spillovers. Third, it points out that besides the already recognized ‘contagion effect,’ trade also promotes technological progress in the LDC through a ‘complementarity effect’ that shifts the resources in the LDC toward the production of more sophisticated intermediate products.
