Intangible Capital and Measured Productivity
Because ?rms invest heavily in R&D, software, brands, and other intangible assets?at a rate close to that of tangible assets?changes in measured GDP, which does not include all intangible investments, understate the actual changes in total output. If changes in the labor input are more precisely measured, then it is possible to observe little change in measured total factor productivity (TFP) coincidentally with large changes in hours and investment. This mismeasurement leaves business cycle modelers with large and unexplained labor wedges accounting for most of the ?uctuations in aggregate ...

Sourcing substitution and related price index biases
We define a class of bias problems that arise when purchasers shift their expenditures among sellers charging different prices for units of precisely defined and interchangeable product items that are nevertheless regarded as different for the purposes of price measurement. For business-to-business transactions, these shifts can cause sourcing substitution bias in the Producer Price Index (PPI) and the Import Price Index (MPI), as well as potentially in the proposed new true Input Price Index (IPI). Similarly, when consumers shift their expenditures for the same products temporally to take ...

The cost of fiscal policy uncertainty: industry evidence of its impact on the labor market
The anemic pace of the recovery of the U.S. economy from the Great Recession has frequently been blamed on heightened uncertainty, much of which concerns the nation's fiscal policy. Intuition suggests that increased policy uncertainty likely has different impacts on industries with different exposure to government actions. Such heterogeneity can help identify the effect of shocks due to policy uncertainty. This study uses industry data to explore whether policy uncertainty indeed affects the dynamics of employment during this recovery, and particularly whether it has a differential impact on ...

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 ...

Micro- and Macroeconomic Impacts of a Place-Based Industrial Policy
We investigate the impact of a set of place-based subsidies introduced in Turkey in 2012. Using firm-level balance-sheet data along with data on the domestic production network, we first assess the policy’s direct and indirect impacts. We find an increase in economic activity in industry-province pairs that were the focus of the subsidy program, and positive spillovers to the suppliers and customers of subsidized firms. With the aid of a dynamic multi-region, multi-industry general equilibrium model, we then assess the program’s impacts. Based on the calibrated model, we find that, in the ...

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 ...

The impact of policy uncertainty on U. S. employment: industry evidence
The anemic pace of the recovery of the U. S. economy from the Great Recession has frequently been blamed on heightened uncertainty, much of which concerns the nation?s fiscal policy. Intuition suggests that increased policy uncertainty likely has different impacts on different industries, to the extent that industries differ in their exposure to government policies. This study utilizes industry data to explore whether policy uncertainty indeed affects the dynamics of employment, and particularly its impact on industry employment, during this recovery. This analysis focuses on heterogeneity ...

Inflation in Disaggregated Small Open Economies
This paper studies inflation in small open economies with production networks. I show that production networks alter the elasticity of the consumer price index (CPI) to changes in sectoral technology, factor prices, and import prices. Sectors can import and export directly but also indirectly through domestic intermediate inputs. Indirect exporting dampens the inflationary pressure from domestic forces, while indirect importing increases the inflation sensitivity to import price changes. Computing these CPI elasticities requires knowledge of the production network structure because these do ...
