Abstract

We study how the technological importance of inputs—measured by cost shares—is related to the decision to “make” or “buy” that input. Using detailed French international trade data and an instrumental variable approach based on self-constructed input–output tables, we show that multinationals vertically integrate technologically important inputs. A stylized incomplete contracting model with both ex-ante and ex-post inefficiencies explains why: Technologically more important inputs are “made” when transaction cost economics type forces overpower property rights type forces. However, additional results show that both types of forces are needed to explain the full patterns in the data.

组织全球供应链：投入产出联系和垂直整合

摘要

我们研究投入的技术重要性（以成本份额衡量）与“制造”或“购买”该投入的决定之间的关系。使用详细的法国国际贸易数据和基于自建投入产出表的工具变量方法，我们表明跨国公司垂直整合技术上重要的投入。具有事前和事后低效率的程式化不完全合同模型解释了原因：当交易成本经济学类型的力量压倒产权类型的力量时，“制造”了技术上更重要的投入。然而，额外的结果表明，需要两种类型的力来解释数据中的完整模式。
