Productivity, congested commuting, and metro size
The monocentric city model is generalized to a fully structural form with leisure in utility, congested commuting, and the equalizing of utility and perimeter land price across metros. Exogenous and agglomerative differences in total factor productivity (TFP) drive differences in metro population, radius, land use, commute time, and home prices. Quantitative results approximate observed correspondences among these outcomes across U.S. metros. Traffic congestion proves the critical force constraining population. Self-driving cars significantly increase the sensitivity of metro population to ...

What Have Workers Done with the Time Freed up by Commuting Less?
The COVID-19 pandemic has dramatically changed the way Americans spend their time. One of the most enduring shifts has occurred in the workplace, with millions of employees making the switch to work from home. Even as the pandemic has waned, more than 15 percent of full-time employees remain fully remote and an additional 30 percent work in hybrid arrangements (Barrero, Bloom, and Davis). These changes have substantially reduced time spent commuting to work; in the aggregate, Americans now spend 60 million fewer hours traveling to work each day. In this post, we investigate how people spend ...

Resource Allocation in Bank Supervision: Trade-offs and Outcomes
We estimate a structural model of resource allocation on work hours of Federal Reserve bank supervisors to disentangle how supervisory technology, preferences, and resource constraints impact bank outcomes. We find a significant effect of supervision on bank risk and large technological scale economies with respect to bank size. Consistent with macro-prudential objectives, revealed supervisory preferences disproportionately weight larger banks, especially post-2008 when a resource reallocation to larger banks increased risk on average across all banks. Shadow cost estimates show tight ...

Labor Market Trends and the Changing Value of Time
During the past two decades, households experienced increases in their average wages and expenditures alongside with divergent trends in their wages, expenditures, and time allocation. We develop a model with incomplete asset markets and household heterogeneity in market and home technologies and preferences to account for these labor market trends and assess their welfare consequences. Using micro data on expenditures and time use, we identify the sources of heterogeneity across households, document how these sources have changed over time, and perform counterfactual analyses. Given the ...

Who Has the Time? Community College Students’ Time-Use Response to Financial Incentives
We evaluate the effect of performance-based scholarship programs for postsecondary students on student time use and effort and whether these effects are different for students we hypothesize may be more or less responsive to incentives. To do so, we administered a time-use survey as part of a randomized experiment in which community college students in New York City were randomly assigned to be eligible for a performance-based scholarship or to a control group that was only eligible for the standard financial aid. This paper contributes to the literature by attempting to get inside the ...

Should Children Do More Enrichment Activities? Leveraging Bunching to Correct for Endogeneity
We study the effects of enrichment activities such as reading, homework, and extracurricular lessons on children's cognitive and non-cognitive skills. We take into consideration that children forgo alternative activities, such as play and socializing, in order to spend time on enrichment. Our study controls for selection on unobservables using a novel approach which leverages the fact that many children spend zero hours per week on enrichment activities. At zero enrichment, confounders vary but enrichment does not, which gives us direct information about the effect of confounders on skills. ...

A concise test of rational consumer search
A simple model of time allocation between work and price-search predicts that consumers spend relatively more time searching for better prices for goods of which they consume relatively more. Using scanner data, we confirm empirically that consumers pay lower (higher) prices for goods that they buy more (less) of than other consumers. Our results are conservative, because we compare goods that are defined as narrowly as possible by UPC codes, and provide a lower bound for the savings obtained from bargain hunting.

Time Use and the Efficiency of Heterogeneous Markups
What are the welfare implications of markup heterogeneity across firms? In standard monopolistic competition models, such heterogeneity implies inefficiency even in the presence of free entry. We enrich the standard model with heterogeneous firms so that preferences are non-separable in off-market time and market consumption and show that this changes the welfare implications of markup heterogeneity. In this context, homogeneity of markups is neither necessary nor sufficient for efficiency. The marginal cost of the marginal firm is weakly inefficiently high when off-market time and market ...

Toward a Framework for Time Use, Welfare, and Household Centric Economic Measurement
What is meant by economic progress, and how should it be measured? The conventional answer is growth in real GDP over time or compared across countries, a monetary measure adjusted for the general rate of increase in prices. However, there is increasing interest in developing an alternative understanding of economic progress, particularly in the context of digitalization of the economy and the consequent significant changes Internet use is bringing about in production and household activity. This paper discusses one alternative approach, combining an extended utility framework considering ...

Home Hours in the United States and Europe
Using data from the Multinational Time Use Study, this paper documents the trends and levels of time allocation, with a focus on home hours, for a relatively large set of industrialized countries during the past 50 years. Three patterns emerge. First, home hours have decreased in both the United States and European countries. Second, female time allocation contributes more to the cross-country difference in both the trends and the levels of market hours and home hours per person. Third, time allocations between the United States and Europe are more similar for the prime-age group than for the ...
