This paper builds on the work of Acemoglu et al. (2012) and considers a production network with unobserved common technological factor and establishes general conditions under which the network structure contributes to aggregate fluctuations. It introduces the notions of strongly and weakly...

I show that inter-firm lending plays an important role in business cycle fluctuations. I first build a tractable network model of the economy in which trade in intermediate goods is financed by supplier credit. In the model, a financial shock to one firm affects its ability to make payments to...

We revisit the debate on the role of technological improvement and market share reallocation in determining aggregate productivity gains. Contrary to previous work that neglects dependencies between suppliers in global value chains, we explicitly account for input linkages that impact both...

The analyses of intersectoral linkages of Leontief (1941) and Hirschman (1958) provide a natural way to study the transmission of risk among interconnected banks and to measure their systemic importance. In this paper we show how classic input-output analysis can be applied to banking and how to...

I show that, under standard assumptions, input-output (or network) economies are equivalent to value-added ones. Using a generalized version of the model in Acemoglu et al. (Econometrica, 2012), I show that the degree of influence of a given sector is equal to its value added share. This occurs...

This paper investigates the relationship between economic growth performances of countries and their structural input-output network characteristics. We employ a new centrality measure developed by Blöchl et al. (2011) for directed networks with self-loops to determine sectoral heterogeneities...

Global Value Chains (GVCs) became the paradigm for the production of most goods and services around the world. Hence, interconnections among countries can no longer be adequately assessed through standard bilateral gross trade flows and new methods of analysis are needed. In this paper, we...

Industrial activity periodically experiences breakthrough innovations in energy efficiency, but the estimated impacts of these innovations on aggregate energy use are highly varied. We develop a general equilibrium model to investigate whether this variation is determined by the structure of the...

Imports feature at all stages of production as well as in final consumption, and this is key to how tariff shocks play out. If imposed on imports in upstream sectors, import tariffs lower domestic output in downstream sectors; if imposed downstream, they raise upstream production. The aggregate...
