The domestic segment of global supply chains in China under state capitalism
This paper proposes methods to incorporate firm heterogeneity in the standard IO-table based approach to portray the domestic segment of global value chains in a country. Using Chinese firm census data for both manufacturing and service sectors, along with constrained optimization techniques, we split the conventional IO table into sub-accounts, which are used to estimate direct and indirect domestic value added in exports of different types of firm. We find that in China, both state-owned enterprises (SOEs) and small and medium domestic private enterprises (SMEs) have much higher shares of ...

Misallocation and Intersectoral Linkages
We analytically characterize the aggregate productivity loss from allocative distortions in a setting that accounts for the sectoral linkages of production. We show that the effects of distortions and the role of sectoral linkages depend crucially on how substitutable inputs are. We find that the productivity loss is smaller if input substitutability is low. Moreover, with low input substitutability, sectoral linkages do not systematically amplify the effects of distortions. In addition, the impact of the sectors that supply intermediate inputs becomes smaller. We quantify these effects in ...

Structural Change in Sub-Saharan Africa: An Open Economy Perspective
We study the evolution of manufacturing value added shares in 11 sub-Saharan African (SSA) countries through the lens of an open economy model of structural change. Our analysis leverages recent developments in input-output tables in SSA countries. Our model allows for income effects via non-homothetic preferences, substitution and relative price effects, as well as comparative advantage and specialization effects. We calibrate our model to include each SSA country with nine other major economies for each year between 2000 and 2018. We also do a similar set of calibrations for 11 developing ...

Sectoral Impact of COVID-19: Cascading Risks
Workers are unequal in the face of the COVID-19 pandemic: Those who work in essential sectors face higher health risk whereas those in non-essential social-consumption sectors face greater economic risk. We study how these health and economic risks cascade into other sectors through supply chains and demand linkages. In the U.S., we find the cascading effects account for about 25-30% of the exposure to both risks. The cascading effect increases the health risk faced by workers in the transportation and retail sectors, and it increases the economic risk faced by workers in the textile and ...
