Making Global Value Chain Research More Accessible

Abstract

Global value chains research has generated a resurgence in Leontief-style input-output analysis, since the introduction of publicly available international input-output (IIO) tables. This paper is designed to clearly present Leontief concepts and applications for international economists who may be largely unaware of these techniques. We present an overview of the structure of IIO tables and related analysis of the sources of value flowing through global production networks. We also provide the methodology to calculate flows to and from specific sectors and regions, with results and code for several examples.

Keywords: global value chains, international input-output tables, trade in value added, Leontief inverse
