What are the long-run effects of permanent changes to the economy? We characterize long-run comparative statics for a broad class of models in terms of expenditure shares, substitution elasticities, and capital supply elasticities. Our key insight is that long-run analysis can be performed using...

We analyze economies with quotas and other quantity-based distortions. We show that any feasible, distorted allocation of resources can be implemented as the competitive equilibrium of an economy with quotas. Unlike economies with wedges, economies with quotas are constrained efficient and thus...

We quantify and explain the firm responses and worker impacts of foreign demand shocks to domestic production networks. To capture that firms can be indirectly exposed to such shocks by buying from or selling to domestic firms that import or export, we use Belgian data with information on both...

We establish the Hurwicz-Uzawa integrability of the broad class of discrete-choice additive random-utility models of individual consumer behavior with perfect substitutes preferences and divisible goods. We derive the corresponding indirect uility function and then establish a representative...

We develop and analyze a new system of disaggregated economic accounts. The system breaks down national accounting positions into bilateral flows among consistently defined subgroups of consumers ("consumer cells"), subgroups of producers ("producer cells"), the government, and the rest of the...

There are large cross-sectional differences in how often US borrowers refinance mortgages. In this paper, we develop an equilibrium mortgage pricing model with heterogeneous borrowers and use it to show that equilibrium forces imply important cross-subsidies from borrowers who rarely refinance...

A slanted-L curve is well-suited to represent the non-linearity of the celebrated Phillips curve. We show this using cross-country data of major industrialized economies since 2009, including the inflationary surge of the 2020s. At high unemployment rates, an increase in demand reduces...

We develop measures of labor-saving and labor-augmenting technology exposure using textual analysis of patents and job tasks. Using US administrative data, we show that both measures negatively predict earnings growth of individual incumbent workers. While labor-saving technologies predict...

As of 2022, the share of U.S. income accruing to labor is at its lowest level since the Great Depression. Updating previous studies with more recent observations, I document the continuing decline of the labor share for the United States, other countries, and various industries. I discuss how...

The deposit business differs at large versus small banks. We provide a parsimonious model and extensive empirical evidence supporting the idea that much of the variation in deposit-pricing behavior between large and small banks reflects differences in "preferences and technologies." Large banks...
