Measuring value circulation in regional chains: assessing two alternative methods in South America
Resumen:
SinceHummels, Ishii and Ye (2001) seminal work there have been lots of proposals for measuring participation in global value chains with input-outputtables. Conjointly to the development of measures, several projects created Inter-Country Input-outputtables. To the extent that integrating data of different origins requires strong assumptions and confidence in sources, some projects keep more detail edinter country input-output tables at a regional level. In this paper I adapt two of the most complete methods conceived for global Input-output tables to the case of regional tables, and I use them to analyze the intraregional value chain trade of South America. Besides characterizing the trade in this region, this paper identifies and asses the differences between adaptations of Borin and Mancini (2019) source-based decomposition of gross exports and the Wang, Wei and Zhu (2018) method.
A partir del artículo de Hummels, Ishii y Ye (2001) se han propuesto varias medidas para medir la participación de los países en cadenas globales de valor. Conjuntamente con el desarrollo de medidas, diversos proyectos crearon Matrices Insumo Producto Multipaís para representar mejor el comercio mundial. Dado que integrar información de muchos países requiere de supuestos fuertes y confianza en las fuentes, algunos proyectos mantienen información detallada en matrices insumos producto regionales. En este artículo se adaptan dos de los métodos más completos concebidos para matrices globales al caso de matrices regionales y se aplican para describir el comercio intrarregional en cadenas en América del Sur. Además de esta caracterización, el artículo mide las diferencias entre la metodología Source-Based de Borin y Mancini (2019) y el método de Wang, Wei y Zhu (2018).
