This paper investigates what features of an economy determine whether convergence under learning is fast or slow. In all of the models that we consider, people's beliefs about model outcomes are central determinants of those outcomes. We argue that under certain circumstances, convergence of a learning equilibrium to the rational expectations equilibrium can be so slow that policy analysis based on rational expectations is very misleading. We also develop new analytic results regarding rates of convergence in learning models.

Rising self-employment rates in U.S. tax data that are absent in survey data have led to speculation that tax records capture a rise in new “gig” work that surveys miss. Drawing on the universe of IRS tax returns, we show that trends in firm-reported payments to “gig” and other contract workers do not explain the rise in self-employment reported to the IRS; rather, that increase is driven by self-reported earnings of individuals in the EITC phase-in range. We isolate pure reporting responses from real labor supply responses by examining births of workers’ first children around an end-of-year cutoff for credit eligibility that creates exogenous variation in tax rates at the end of t..

In many market-design applications, a new mechanism is introduced to reform an existing institution. Compared to the design of a mechanism in isolation, the presence of a status-quo system introduces both challenges and opportunities for the designer. We study this problem in the context of reforming the mechanism used to assign Child Protective Services (CPS) investigators to reported cases of child maltreatment in the U.S. CPS investigators make the consequential decision of whether to place a child in foster care when their safety at home is in question. We develop a design framework built on two sets of results: (i) an identification strategy that leverages the status-quo random assignme..

This paper studies long-run differences in intergenerational occupational mobility between Black and White Americans. Combining data from linked historical censuses and contemporary large-scale surveys, we provide a comprehensive set of mobility measures based on Markov chains that trace the short- and long-run dynamics of occupational differences. Our findings highlight the unique importance of changes in mobility experienced by the 1940–1950 birth cohort in shaping the current occupational distribution and reducing the racial occupational gap. We further explore the properties of continuing occupational inequalities and argue that these disparities are better understood by a lack of exch..

Using population-level administrative data, we study labor market externalities stemming from age-specific employment protection legislation (EPL) targeted towards older workers. Our results show no economically meaningful overall effects of the EPL on employment or earnings of either men or women approaching eligibility. Considering separately incumbent workers and non-employees we find small positive and small negative employment effects for the former and the latter groups, respectively.

This article provides an overview of the literature on mobility in developing countries. Explicit distinctions are drawn between directional and non-directional measures, absolute and relative measures, and combinations thereof. We note that the scarcity of panel data has hindered the measurement of mobility for many countries. We pay particular attention to the recent development of panel-free mobility measures, which allows us to measure upward mobility in 122 countries. Throughout this review, we discuss some central themes in the literature.

Transparency vs. opacity is an important dimension of college admission policy. Colleges may gain useful information from a holistic review of applicants’ materials, but in doing so may contribute to uncertainty that discourages potential applicants with poor information. This paper investigates the impacts of admissions transparency in the context of Texas’ Top Ten Percent Plan, using survey and administrative data from Texas and a model of college applications, admissions, enrollment, grades, and persistence. I estimate that two thirds of the plan’s 9.1 point impact on top-decile students’ probability of attending a flagship university was due to information rather than mechanical ..

The estimation of racial disparities in various fields is often hampered by the lack of individual-level racial information. In many cases, the law prohibits the collection of such information to prevent direct racial discrimination. As a result, analysts have frequently adopted Bayesian Improved Surname Geocoding (BISG) and its variants, which combine individual names and addresses with Census data to predict race. Unfortunately, the residuals of BISG are often correlated with the outcomes of interest, generally attenuating estimates of racial disparities. To correct this bias, we propose an alternative identification strategy under the assumption that surname is conditionally independent o..

We use two surveys to assess why work from home (WFH) varies so much across countries and people. A measure of cultural individualism accounts for about one-third of the cross-country variation in WFH rates. Australia, Canada, the UK, and the US score highly on individualism and WFH rates, whereas Asian countries score low on both. Other factors such as cumulative lockdown stringency, population density, industry mix, and GDP per capita also matter, but they account for less of the variation. When looking across individual workers in the United States, we find that industry mix, population density and lockdown severity help account for current WFH rates, as does the partisan leaning of the c..

Are labor markets in higher-income countries more meritocratic, in the sense that worker-job matching is based on skills rather than idiosyncratic attributes unrelated to productivity? If so, why? And what are the aggregate consequences? Using internationally comparable data on worker skills and job skill requirements of over 120,000 individuals across 28 countries, we document that workers' skills better match their jobs' skill requirements in higher-income countries. To quantify the role of worker-job matching in development accounting, we build an equilibrium matching model that allows for cross-country differences in three fundamentals: (i) the endowments of multidimensional worker skill..

In 2020, local governments in China began issuing digital coupons to stimulate spending in targeted categories such as restaurants and supermarkets. Using data from a large e-commerce platform and a bunching estimation approach, we find that the coupons caused large increases in spending of 3.1–3.3 yuan per yuan spent by the government. The large spending responses do not come from substitution away from non-targeted spending categories or from short-run intertemporal substitution. To rationalize these results, we develop a dynamic consumption model showing how coupons’ minimum spending thresholds create temporary notches that lead to large spending responses.

Does international trade affect the growth of cities, and vice versa? Assembling disaggregate data for four countries, we document a novel stylized fact: Export activity is disproportionately concentrated in larger cities – even more so than overall economic activity. We rationalize this fact by marrying a standard quantitative spatial economics model with a heterogeneous firm model that features selection into the domestic and the export market. Our model delivers novel predictions for the bi-directional interactions between trade and urban dynamics: On the one hand, trade liberalization shifts employment towards larger cities, and on the other hand, liberalizing land use raises exports. ..

Research on centralized school assignment mechanisms often focuses on whether parents who participate in specific mechanisms are likely to truthfully report their preferences or engage in various costly strategic behaviors. However, a growing literature suggests that parents may not know enough about the school options available to them to form complete preference rankings. We develop a simple model that explains why it is not surprising that many participants in school assignment mechanisms possess limited information about the schools available to them. We then discuss policies that could improve both the information that participants bring to school assignment mechanisms and the quality o..

We document novel survey-based facts on preferred long-run inflation rates among U.S. consumers. Consumers on average prefer a 0.20% annual inflation rate, considerably below the Federal Reserve’s 2% target. Inflation preferences not only correlate with demographic and socioeconomic characteristics, but also with economic reasoning. A randomized control trial reveals that two narratives based on economic models—describing how inflation lowers the real value of wages as well as money holdings—affect inflation preferences. While our results can inform the design of central bank communication on inflation targets, they also raise questions about the alignment between such targets and cons..

We examine the labor supply impact of a 2016 policy that allows retirement-eligible individuals covered by Peru’s private pension system to receive retirement benefits as a lump sum rather than as an annuity. We present a theoretical model predicting that, for liquidity constrained workers, the lump sum option makes formal employment (requiring pension participation) more attractive relative to informal employment (not requiring pension participation); it also encourages early retirement. Using household panel data, we estimate the impact of the 2016 policy on the labor supply of workers covered by the private pension system compared to workers covered by the alternative pay-as-you-go defi..

We present an approach for automatically generating and testing, in silico, social scientific hypotheses. This automation is made possible by recent advances in large language models (LLM), but the key feature of the approach is the use of structural causal models. Structural causal models provide a language to state hypotheses, a blueprint for constructing LLM-based agents, an experimental design, and a plan for data analysis. The fitted structural causal model becomes an object available for prediction or the planning of follow-on experiments. We demonstrate the approach with several scenarios: a negotiation, a bail hearing, a job interview, and an auction. In each case, causal relationshi..

Social protection programs have become increasingly widespread in low- and middle-income countries, with their own distinct characteristics to match the environments in which they are operating. This paper reviews the growing literature on the design and impact of these programs. We review how to identify potential beneficiaries given the large informal sector, the design and implementation of redistribution and income support programs, and the challenges and potential of social insurance. We use our frameworks as a guide for consolidating and organizing the existing literature, and also to highlight areas and questions for future research.

We create a dataset of 14,000 hand-coded help–wanted advertisements placed by employment agencies in three U.S. newspapers in 1950 and 1960, a time when help–wanted advertisements were divided into male and female sections, and collect information on agency ownership. We find that female-owned agencies specialized in vacancies for women, thereby expanding the access of female jobseekers to agency services, including for positions in majority-male occupations. Female-owned agencies advertised more skilled occupations to women than did male-owned agencies, leading to a 5.5% higher wage for women. On the other hand, female-owned agencies had a greater propensity to match male jobseekers to ..

We examine the long transition from water to steam power in US manufacturing, focusing on early users of mechanical power: lumber and flour mills. Digitizing Census of Manufactures manuscripts for 1850 to 1880, we show that as steam costs declined, manufacturing activity grew faster in counties with less waterpower potential. This growth was driven by steam powered entrants and agglomeration, as water powered incumbents faced switching barriers primarily from sunk costs. Estimating a dynamic model of firm entry and steam adoption, we find that the interaction of switching barriers and high fixed costs creates a quantitatively important and socially inefficient drag on technology adoption. De..

We examine the impacts of ethical declarations on market transactions through a controlled laboratory experiment, where privately-informed sellers issue a public report prior to a first-price auction. We find that while signing an ethical statement does not reduce misreporting by sellers, it significantly increases buyer trust, often skewing the terms of the trade in favor of sellers. Contrary to rational expectations, buyers consistently struggle to undo the bias. In counterfactual scenarios, from our structural analysis, we find that price efficiency improves when buyers rationally process uncertainty about sellers' ethical preferences, yet bias persists even when buyers have more accurate..

We examine the state of the U.S. K-12 teaching profession over the last half century by compiling nationally representative time-series data on four interrelated constructs: occupational prestige, interest among students, the number of individuals preparing for entry, and on-the-job satisfaction. We find a consistent and dynamic pattern across every measure: a rapid decline in the 1970s, a swift rise in the 1980s extending into the mid 1990s, relative stability, and then a sustained decline beginning around 2010. The current state of the teaching profession is at or near its lowest levels in 50 years. We identify and explore a range of hypotheses that might explain these historical patterns ..

We begin by examining determinants of aggregate foreign exchange reserve holdings by central banks (size of issuing country’s economy and financial markets, ability of the currency to hold value, and inertia). But understanding the determination of reserve holdings probably requires going beyond the aggregate numbers, instead observing individual central bank behavior, including characteristics of the holding country (bilateral trade with the issuing country, bilateral currency peg, and proxies for bilateral exposure to sanctions), in addition to the characteristics of the reserve currency issuer. On a currency-by-currency basis, US dollar holdings are somewhat well explained by several is..

Mastery learning - the process by which students must demonstrate proficiency with a single topic before moving on - is well recognized as one of the most effective ways to learn, yet many teachers struggle or remain unsure about how to implement it into a classroom setting. This study evaluates a program to encourage greater mastery learning through technology and proactive continuous teacher support. Focusing on elementary and middle school mathematics, teachers receive weekly coaching in how to use Computer Assisted Learning (CAL) for helping students follow a customized roadmap of incremental progress. Results from two field experiments indicate significant Intent To Treat effects on mat..

In this article we revive, extend and improve the approach used in a series of influential papers written in the 2000s to estimate how changes in the supply of immigrant workers affected natives' wages in the US. We begin by extending the analysis to include the more recent years 2000-2022. Additionally, we introduce three important improvements. First, we introduce an IV that uses a new skill-based shift-share for immigrants and the demographic evolution for natives, which we show passes validity tests and has reasonably strong power. Second, we provide estimates of the impact of immigration on the employment-population ratio of natives to test for crowding out at the national level. Third,..

In 2015, Michigan increased its Career and Technical Education (CTE) funding and changed its funding formula to reimburse programs-based student progression through program curricula. Although this change nearly doubled program completion rates, student enrollment and persistence were unaffected; instead, administrators accelerated student progress by reorganizing course curricula around notches in the new funding formula. As a result of response heterogeneity, 30% of the funding increase is transferred away from high-poverty districts to more affluent ones, underscoring how supply-side responses to loopholes shape the incidence of public services.

The largest tax-based social welfare programs in the US limit their benefits to taxpayers with labor market income. Eliminating these work requirements would better target transfers to the neediest families but risks attenuating tax-based incentives to work. We study changes in labor force participation from the elimination of a work requirement in a tax credit for parents of young children, drawing on quasi-random variation in birth timing and administrative tax records. To do so, we develop and implement a novel approach for selecting an empirical specification to maximize the precision of our estimate. The unique design of the policy along with its subsequent reform allow us to isolate ta..

Equally educated people are healthier if they live in more educated places. Every 10 percent point increase in an area’s share of adults with a college degree is associated with a decline in all-cause mortality by 7%, controlling for individual education, demographics, and area characteristics. Area human capital is also associated with lower disease prevalence and improvements in self-reported health. The association between area education and health increased greatly between 1990 and 2010. Spatial sorting does not drive these externalities; there is little evidence that sicker people move disproportionately into less educated areas. Differences in health-related amenities, ranging from h..

We study the effectiveness of firms' compliance programs by conducting a field experiment in which we disclose to a subset of Japanese firms that the firm is potentially engaging in illegal bid-rigging. We find that the information that we disclose affects the bidding behavior of the treated firms: our test of bid-rigging is less able to reject the null of competition when applied to the bidding data of the treated firms after the intervention. We find evidence that this change is not the result of firms ceasing to collude, however. We find evidence suggesting that firms continue to collude even after our intervention and that the change in the bidding behavior we document is the result of a..

This article provides empirical researchers with an introduction and guide to research designs based on variation in judge and examiner tendencies to administer treatments or other interventions. We review the basic theory behind the research design, outline the assumptions under which the design identifies causal effects, describe empirical tests of those assumptions, and discuss tradeoffs associated with choices researchers must make for estimation. We demonstrate concepts and best practices concretely in an empirical case study that uses an examiner tendency research design to study the effects of pre-trial detention.

We analyze data from two universities that allowed students to conceal grades from their transcripts during the Covid-19 pandemic. Across both institutions, we observe a significant and substantial gender concealment gap: women are less likely than men to conceal grades that would harm their GPA. We explore the robustness, drivers, and consequences of the concealment gap via rich data on student traits and course-level characteristics as well as complementary data from an experiment with real employers and a survey of impacted students. Our findings highlight how information-optional policies can create unexpected and potentially undesirable disparities.
