We estimate the effects of government spending along the supply chain using disaggregated U.S. government procurement data. We first identify sectoral public spending shocks and combine them with input-output tables to measure upstream and downstream exposure through the production network. We...

We study the consequences of protectionism for macroeconomic fluctuations. First, using high-frequency trade policy data, we present fresh evidence on the dynamic effects of temporary trade barriers. Estimates from country-level and panel VARs show that protectionism acts as a supply shock,...

Using monthly data on temporary trade barriers (TTBs), we estimate the dynamic employment effects of protectionism through vertical production linkages. First, exploiting procedural details of TTBs and high-frequency data, we identify movements in protectionism exogenous to economic...

It has long been argued that cyclical fluctuations in labor and capital utilization and the presence of overhead labor and capital are important for explaining procyclical productivity. Here I present two simple and direct tests of these hypotheses, and a way of measuring the relative importance...

This paper presents an aggregate demand-driven model of business cycles that provides a new explanation for the procyclicality of productivity, and simultaneously predicts large welfare losses from monetary non-neutrality. The key features of the model are an input- output production structure,...

A number of recent papers have argued that US firms exert increasing market power, as measured by their markups of price over marginal cost. I review three of the main approaches to estimating economy-wide markups and show that all are based on the hypothesis of firm cost-minimization. Yet...

"We prove that the change in welfare of a representative consumer is summarized by the current and expected future values of the standard Solow productivity residual. The equivalence holds if the representative household maximizes utility while taking prices parametrically. This result justifies...

Yes. We construct a measure of aggregate technology change, controlling for varying utilization of capital and labor, non-constant returns and imperfect competition, and aggregation effects. On impact, when technology improves, input use and non-residential investment fall sharply. Output...

We argue that unmeasured investments in intangible organizational capital associated with the role of information and communications technology (ICT) as a general purpose technology' can explain the divergent U.S. and U.K. TFP performance after 1995. GPT stories suggest that measured TFP should...

Modern monetary business-cycle models rely heavily on price and wage rigidity. While there is substantial evidence that prices do not adjust frequently, there is much less evidence on whether wage rigidity is an important feature of real world labor markets. While real average hourly earnings...
