Supply chain problems, previously relegated to specialized journals, now appear in G7 Leaders' Communiqués. Our paper looks at three core elements of the problems: measurement of the links that expose supply chains to disruptions, the nature of the shocks that cause the disruptions, and the...

For a finer analysis of global value chain integration and competitiveness, we develop and apply a method for a micro-data based breakdown of manufacturing industries in the 2010 Belgian supply-and-use tables into export-oriented and domestic market firms. The former are defined as those firms...

This paper presents experimental tables created by the U.S. Bureau of Economic Analysis comparing industry-specific shares of the components of total output of globally engaged firms located in the United States that are part of a multinational enterprise with those of firms that are part of an...

We analyze persuasion in a model in which each receiver can buy a direct access to the sender's signal or rely on her network connections to get it. For the sender, a higher bias increases the impact per direct receiver, yet diminishes the willingness of agents to receive information. Contrary...

This paper develops a framework for studying the macroeconomic costs of resource misallocation. The framework enables the assessment of the conditions under which the existing estimates in the misallocation literature, which are largely based on a value-added production structure and ignore...

Britain's repeal of the Corn Laws in 1846 was the signature trade policy event of the nineteenth century. This paper provides a quantitative general equilibrium evaluation of the repeal on sectoral output and employment, factor prices and income distribution, international trade and the terms of...

We associate a dynamical system with input-output networks and study its spectral properties. Specifically, we develop a dynamic production network model featuring adjustment costs of changing inputs and thus gradual recovery from temporary TFP shocks. First, we explicitly solve for the output...

The Covid-19 crisis is an unusual and seemingly all-encompassing economic shock. On the one hand, it was unquestionably a negative demand shock that, for fixed prices and incomes, reduced household spending. On the other hand, it was also unquestionably a negative supply shock that reduced...

We develop a tractable model of endogenous production networks. Each one of a number of products can be produced by combining labor and an endogenous subset of the other products as inputs. Different combinations of inputs generate (prespecified) levels of productivity. Markets are "contestable"...
