We extend the regional input-output model for the economic impact assessment of Covid-19 lockdowns in Italy proposed in Reissl et al. (2021) by incorporating the effects of changes in mobility on the level and composition of consumption demand. We estimate the model on sectoral data for 2020 and...

This paper argues that, in the presence of intersectoral input–output linkages, microeconomic idiosyncratic shocks may lead to aggregate fluctuations. We show that, as the economy becomes more disaggregated, the rate at which aggregate volatility decays is determined by the structure of the...

Natural and anthropogenic disasters frequently affect both the supply and demand side of an economy. A striking recent example is the COVID-19 pandemic which has created severe industry-specific disruptions to economic output in most countries. Since firms are embedded in production networks,...

Economic shocks due to COVID-19 were exceptional in their severity, suddenness and heterogeneity across industries. To study the upstream and downstream propagation of these industry-specific demand and supply shocks, we build a dynamic input-output model inspired by previous work on the...

This paper argues that in the presence of intersectoral input-output linkages, microeconomic idiosyncratic shocks may lead to aggregate fluctuations. In particular, it shows that, as the economy becomes more disaggregated, the rate at which aggregate volatility decays is determined by the...

This paper studies the general equilibrium effects of industry-specific productivity shock in an economy in which sectors are connected via input-output linkages. My central finding is productivity shocks do not only travel downstream as is standard in the literature, but also trigger demand...

We extend a quantitative general equilibrium model of global trade networks to evaluate the economic impacts of various trade disruptions. Our analysis considers scenarios such as US-China trade wars, a broader Cold War 2.0 decoupling, Trump-era tariffs, and disruptions in the trade of critical...

This paper studies a number of features of transaction networks, firm sales growth, and buyer-supplier comovements of sales using a large-scale dataset on the Japanese interfirm transaction network. Larger firms have higher sales growth rates and smaller growth dispersion. Well-connected firms...

We develop a network trade model with country-sector level input-output linkages. It includes (1) domestic and global value chain linkages between all country-sectors, (2) direct as well as indirect shipments (via other sectors and countries) to a final destination, (3) value added rather than...

This study uses input-output labor-accounting to estimate the impact of rising imports from China on US employment. Our counterfactual analysis incorporates offsets from substitution for imports from other countries, increased US exports to China and other countries, and job gains in downstream...
