This paper provides one of the first estimates of elasticities of substitution across suppliers within the same product. This paper estimates these elasticities using new real-time administrative tax data on firm-to-firm transactions, with product-level prices and quantities, leveraging...

We propose a novel measure to investigate firms' product specialisation: product coreness, that captures the centrality of exported products within the firm's export basket. We study product coreness using firm-product level data between 2018 and 2020 for Colombia, Ecuador, and Peru. Three main...

We study how technology adoption and changes in global value chain (GVC) integration jointly affect labor shares and business function specialization in a sample of 14 manufacturing industries in 14 European countries in 1999-2011. Our main contribution is to highlight the indirect effect of...

We analyze the effects of disasters on the global value chain based on comprehensive data from 62 countries between 2007 and 2020. On average, a typical disaster reduces total exports by -1.48%, inter-mediate exports by -1.69%, forward linkage by -1.93%, and backward linkage by -1.77%. These...

After China's accession to WTO in 2001, it has substantially reduced its own import tariffs, and since then the participation of China’s various industries in global value chains have all deepened steadily(GVC afterward). The traditional wisdom about import tariff is that proper levels of...

We construct a new database which covers production and trade in 136 primary commodities and 24 manufacturing and service sectors for 145 countries. Using this new more granular data, we estimate spillover effects from plausible trade fragmentation scenarios in a new multi-country, multi-sector,...

As countries and firms increasingly seek ways to strengthen the resilience of their supply chains, this paper studies the global economic costs of a decoupling of global supply chains along geopolitical lines as well as in strategic sectors. We explore not only the long-run effects, but also the...
