Integrated epi‐econ assessment: Quantitative theory Open
Aimed at pandemic preparedness, we construct a framework for integrated epi‐econ assessment that we believe would be useful for policymakers, especially at the early stages of a pandemic outbreak. We offer theory, calibration to micro‐, ma…

A Theory of Falling Growth and Rising Rents Open
Growth has fallen in the U.S. amid a rise in firm concentration. Market share has shifted to low labour share firms, while within-firm labour shares have actually risen. We propose a theory linking these trends in which the driving force i…

Productivity Slowdown: Reducing the Measure of Our Ignorance Open
Growth accounting suggests that the bulk of the post-2004 slowdown in output growth in the U.S. is attributed to a residual called TFP. In this paper we provide a tractable accounting framework with firm heterogeneity to link this residual…

Rising inequality and trends in leisure Open
This paper develops a model that generates rising average leisure time and increasing leisure inequality along a path of balanced growth. Households derive utility from three sources: market goods, home goods and leisure. Home production a…

Integrated Epi-Econ Assessment Open
We formulate an economic time use model and add to it an epidemiological SIR block.In the event of an epidemic, households shift their leisure time from activities with a high degree of social interaction to activities with less, and also …

Replication data for: Missing Growth from Creative Destruction Open
For exiting products, statistical agencies often impute inflation from surviving products. This understates growth if creatively-destroyed products improve more than surviving ones. If so, then the market share of surviving products should…

Firm Dynamics and Growth Measurement in France Open
Statistical agencies typically impute inflation for disappearing products based on surviving products, which may result in overstated inflation and understated growth. This paper uses the theory and methodology developed by Aghion et al. (…

Exploiting MIT Shocks in Heterogeneous-Agent Economies: The Impulse Response as a Numerical Derivative Open
We propose a new method for computing equilibria in heterogeneous-agent models with aggregate uncertainty.The idea relies on an assumption that linearization offers a good approximation; we share this assumption with existing linearization…

Statistical agencies typically impute inflation for disappearing products based on surviving products, which may result in overstated inflation and understated growth.Using U.S. Census data, we apply two ways of assessing the magnitude of …

Missing Growth from Creative Destruction Open
When products exit due to entry of better products from new producers, statistical agencies typically impute inflation from surviving products. This understates growth if creatively-destroyed products improve more than surviving products. …

Labor Supply in the Past, Present, and Future: a Balanced-Growth Perspective Open
We argue that a stable utility function of consumption and hours worked for which income effects are slightly stronger than substitution effects can rationalize the long-run data for the main macroeconomic quantities. In these long-run dat…
