Production networks and economic policy
展示如何结合投入产出表数据和生产网络理论来指导政策制定，并利用法国数据说明生产网络如何影响竞争政策对整体经济的作用。
Abstract In this paper, we show how to combine data on input–output tables and recent insights from the theory of production networks in order to inform policy. We first describe the information contained in input–output tables compiled by statistical agencies, and show how to derive relevant statistics of production networks. We then discuss the implications of production networks for policy intervention in a series of domains, such as fiscal policy, industrial policy, or, finance. Finally, we present a quantitative exercise applied to French data in order to illustrate that production networks shape the overall impact of competition policy on the economy.
