Working Papers

College Attrition and the Dynamics of Information Revelation
with Peter Arcidiacono, Esteban Aucejo, and Arnaud Maurel.
Also available as NBER Working Paper No. 22325
R & R, Journal of Political Economy (May 31, 2016)

This paper investigates the role played by informational frictions in college and the workplace. We estimate a dynamic structural model of schooling and work decisions, where individuals have imperfect information about their schooling ability and labor market productivity. We take into account the heterogeneity in schooling investments by distinguishing between two- and four-year colleges, graduate school, as well as science and non-science majors for four-year colleges. Individuals may also choose whether to work full-time, part-time, or not at all. A key feature of our approach is to account for correlated learning through college grades and wages, whereby individuals may leave or re-enter college as a result of the arrival of new information on their ability and productivity. Our findings indicate that the elimination of informational frictions would increase the college graduation rate by 9 percentage points, and would increase the college wage premium by 32.7 percentage points through increased sorting on ability.

Do High School Sports Build or Reveal Character?
with Michael R Ransom.
Also available as IZA Discussion Paper No. 11110
Under Review (October 21, 2017)

We examine the extent to which participation in high school athletics has beneficial effects on future education, labor market, and health outcomes. Due to the absence of plausible instruments in observational data, we use recently developed methods that relate selection on observables with selection on unobservables to estimate bounds on the causal effect of athletics participation. We analyze these effects in the US separately for men and women using three different nationally representative longitudinal data sets that each link high school athletics participation with later-life outcomes. We do not find consistent evidence of individual benefits reported in many previous studies—once we have accounted for selection, high school athletes are no more likely to attend college, earn higher wages, or participate in the labor force. However, we do find that men (but not women) who participated in high school athletics are more likely to exercise regularly as adults. Nevertheless, athletes are no less likely to be obese.

The Effect of Business Cycle Fluctuations on Migration Decisions
(February 25, 2016)

I examine mechanisms that differentially influence migration behavior in response to labor market shocks between employed and unemployed workers in the US. Over the period of the Great Recession, overall migration rates in the US remained close to their respective long-term trends. However, migration evolved differently by employment status with unemployed workers being more likely to migrate during the recession and employed workers less likely. I estimate a dynamic non-stationary search model of migration, focusing on the role of employment frictions, earnings, and amenities on migration decisions. My results show that employed workers are faced with a large job queuing penalty when moving locations, which results in differing migration incentives for the two groups when faced with adverse labor market shocks. I also find that migration rates were muted because of the national scope of the Great Recession. I show that moving subsidies aimed at mitigating local unemployment are greatly hindered by workers' preferences for amenities.

Do Foreigners Crowd Natives out of STEM Degrees and Occupations? Evidence from the U.S. Immigration Act of 1990
with John V. Winters.
Also available as IZA Discussion Paper No. 9920
(May 27, 2016)

The U.S. Immigration Act of 1990 increased the in-flow and stock of foreign STEM workers, potentially altering the desirability of STEM degree fields and occupations for natives. We examine effects of the Act utilizing spatial and temporal variation in natives’ exposure to foreign STEM with a novel identification strategy focused on age-18 cohorts immediately before and after the policy change. We find that the Immigration Act changed natives’ skill investment and utilization by pushing black males out of STEM majors, pushing white male STEM graduates out of STEM occupations, and pushing white female STEM graduates out of the workforce.

Changes across Cohorts in Wage Returns to Schooling and Early Work Experiences
with Jared Ashworth, V. Joseph Hotz, and Arnaud Maurel.
(November 28, 2016)

This paper investigates the wage returns to schooling and early work experiences and how these returns have changed across several recent cohorts of men. Much has been written about the growing importance of the wage returns to additional years of schooling and degree attainment. Most of these studies give little attention to the returns to the types and actual amounts of work experience young adults acquire and their influence on wages. This paper examines the returns to both school and work for men from three birth cohorts, using longitudinal data from the 1979 and 1997 panels of the National Longitudinal Survey of Youth. We develop and estimate a dynamic model of the schooling and work choices these men make in early adulthood and how they affect wage growth. We find that (i) ignoring the selectivity of accumulated work experiences results in sizable overstatements of the wage returns to schooling or degree attainment; (ii) with few exceptions, the returns to schooling and work experiences have trended downward over time; and (iii) decomposing the changes in the returns to skill reveals a downward trend in the level of unobserved ability of workers who acquire in-school work experience or who obtain formal educational degrees.

Selective Migration, Occupational Choice, and the Wage Returns to College Majors
(December 27, 2016)

I examine the extent to which the returns to college majors are influenced by selective migration and occupational choice across locations in the US. To quantify the role of selection, I develop and estimate an extended Roy model of migration, occupational choice, and earnings where, upon completing their education, individuals choose a location in which to live and an occupation in which to work. In order to estimate this high-dimensional choice model, I make use of machine learning methods that allow for model selection and estimation simultaneously in a non-parametric setting. I find that OLS estimates of the returns to business and STEM majors relative to education majors are upward biased by 15% on average and by as much as 30%. Using estimates of the model, I characterize the migration behavior of different college majors and find that migration flows are twice as sensitive to occupational concentration as they are to wage returns. This finding has important implications for local governments seeking to attract or retain skilled workers.

Works in Progress

Understanding Migration Aversion Using Elicited Expectations and Counterfactuals

Migration within the United States has been declining for decades across all demographic subgroups, despite overwhelming evidence of benefits to moving out of a location that is in economic or population decline. At the same time, existing studies find substantial monetary and psychic costs to moving. To better understand the the determinants of individuals’ migration aversion, I analyze data that elicits preferences for one’s current location and probabilities of moving to another location under a set of counterfactual scenarios. These scenarios include employment prospects, social interactions, and financial considerations. I find that the loss of one’s own job or spouse’s job negatively impacts migration beliefs by 10 percentage points. On the other hand, receiving a similar or much better job in a new location positively impacts migration beliefs by 20 percentage points. Equally important to migration beliefs are the ability to move with one’s social network, and having the financial costs of the move paid for. These results point to the joint importance of job lock, social interactions, and monetary costs in explaining migration aversion. The findings are especially informative to policy that seeks to induce migration out of declining areas.

How Substitutable are Native- and Foreign-born Workers? Wage Effects from STEM In-flow
with John V. Winters.

We study heterogeneity in the effect of immigrant labor supply on native wages in the United States using quasi-experimental variation induced by the Immigration Act of 1990. The Act quickly and substantially increased the number of immigrant workers in STEM occupations. Using CPS data, we find short-run policy effects of reduced wages for more substitutable workers but increased wages for more complementary workers. We analyze long-term effects of the policy using administrative earnings data and find smaller long-run effects.

Beating the Heat: Temperature and Spatial Reallocation over the Long Run
with Christos Makridis.

Does temperature affect real economic activity? Using the annual Current Population Survey between 1963 and 2015, we show that there is no association between temperature and earnings, hours, or output after controlling for time-invariant spatial heterogeneity and time-varying demographic factors. These results are robust to five separate sources of micro-data, different sampling horizons, functional forms, spatial measures of temperature, and subsets of the data. This paper studies the relationship between temperature and productivity across space and time. Motivated by these null results, we develop a spatial equilibrium model where temperature can affect not only firm productivity, but also individual locational choice. After calibrating the model, we use it to disentangle the role of reallocation versus actual productivity losses in the U.S. economy between 1980 and 2015. Nearly all of the variation is driven by reallocation. We subsequently use the model to evaluate a counterfactual climate scenario and recover a new spatial equilibrium for the U.S. economy by 2050.
