Can participation in safety net programs have long-lasting negative effects across multiple generations? We take advantage of a 1993 Dutch disability insurance reform which tightened requirements and lowered benefits for participants. We study the third generation 25 years after the reform, finding that grandchildren of individuals whose DI eligibility and benefits were reduced are less likely to be born premature, have low birthweight, or experience complicated deliveries. They also have better health and schooling outcomes during early childhood. These early-life improvements are consequential, as they have been linked to better health, education, and labor market outcomes in adulthood.

We conduct a meta-analysis of distributional preferences, examining 297 estimates of sensitivity to inequality from 41 articles that structurally estimate the Fehr and Schmidt (1999) model. Our analysis indicates that individuals are inequality averse: mean sensitivity to disadvantageous and advantageous inequality are, respectively, 0.533 and 0.326. We also uncover systematic heterogeneity: aversion to advantageous (disadvantageous) inequality is smaller (larger) in strategic environments. Finally, we examine 98 estimates of altruism and attitude towards equity versus efficiency from 17 studies structurally estimating the Andreoni and Miller (2002) model. The representative individual displays Cobb–Douglas preferences with roughly 1/3 weight on others’ earnings.

When employers face a trade-off between being large and paying low wages—and in this sense have monopsony power—some productive employers decide against building large business networks, forgo sales, and remain small. These decisions have adverse consequences for aggregate labour productivity. Using high-quality administrative data from Germany, we document that East German plants (compared to West German ones) face steeper size-wage curves, invest less in their business networks, remain smaller, and are less productive. A model with labour market monopsony, product market power, and business network investments matching these features of the data predicts a 10% lower aggregate labour productivity in East Germany.

This paper studies the long-term effects of technology and know-how transfers on structural transformations. In the 1950s, the Soviet Union supported the construction of the 156 Projects, which were large-scale, capital-intensive industrial clusters in China. These projects included a technology transfer, consisting of state-of-the-art Soviet machinery and equipment, and a know-how transfer, via the training of Chinese engineers, production supervisors, and high-skilled technicians by Soviet experts. We use newly assembled data that follow steel plants for over four decades, and we exploit natural variation in the transfers they eventually received. We find that, while production advantages stemming from Soviet technology faded away if not complemented with training, the know-how transfer had a long-lasting impact on plant performance, stimulated technology upgrade when China was a closed economy, and increased exports to the Western world when China engaged in international trade. The know-how transfer also generated productivity and technology spillovers onto complementary establishments.

Seminal theories of the firm posit that firm ownership is allocated to minimize contractual inefficiencies. Yet, it remains unclear how much the optimal ownership choice affects firm performance in practice. This paper provides a first quantification of the gains from optimal ownership within multinational firms by exploiting a major liberalization of China’s policy restrictions on foreign ownership. The liberalization allowed previously restricted firms to become fully foreign-owned. We find that these reoptimized ownership choices raise firm output by 40% and productivity by 7.5% on average. An extended property-rights theory of the multinational firm rationalizes these effects and their heterogeneity.

This article evaluates the impact of the Chinese minimum-wage policy on consumption of low-wage households for the period 2002–2009. Using a representative panel of urban households, we find that the consumption response to minimum-wage income hikes increases in the share of minimum-wage income in total household income. In particular, poorer households fully consume their additional income, while meaningful negative employment effects are absent. The large marginal propensity to consume is driven by households with at least one child, while poor, childless households save two-thirds of a minimum-wage hike. The expenditure increase is concentrated in health care and education with potentially long-lasting benefits to household welfare.

This paper provides novel evidence on the causal effect of high school Grade Point Average (GPA) on the human capital development and labor market trajectory of individuals. Causal identification is achieved by exploiting a unique feature of the Norwegian education system that produces exogenous variation in GPA among high school students. We find little effect on the number of completed years of higher education, but significant effects on the number and quality of higher education programs available to students after high school. Most importantly, we find persistent effects on students’ long-run labor market outcomes, most notably market wage.

I use newly digitized contract data on U.S. war production spending over 1940–1945 to analyze the macroeconomic effects of U.S. military spending in World War II. I find personal income multipliers of 0.34 over two years and 0.49 over three years. Personal income multipliers may substantially understate gross domestic product multipliers, perhaps by as much as 50%. Employment estimates imply costs per job-year over the same time horizons of $405,013 and $232,268 in 2015 dollars, suggesting job creation was limited. I also find evidence of negative scale effects: larger positive spending shocks are associated with systematically smaller multiplier estimates.

We propose a Cramér–von Mises–type test for testing whether the mean potential outcome given a specific treatment level has a weakly monotonic relationship with the continuous treatment under unconfoundedness. To flexibly control for a possibly high-dimensional set of covariates, our test is based on a double debiased machine learning method. We show that our test controls asymptotic size and is consistent against any fixed alternative. We apply our test to evaluate the Job Corps program and reject a weakly negative relationship between the treatment (hours in academic and vocational training) and labor market performance among relatively low treatment values.

We assess the predictive power of two measures of competitiveness for education and labor market outcomes using a large, representative survey panel. The first is incentivized and is an online adaptation of the laboratory-based Niederle-Vesterlund measure. The second is an unincentivized survey question eliciting general competitiveness. Both measures are strong predictors of income, occupation, level of education, and field of study. The predictive power of the new unincentivized measure is robust to controlling for other traits, including risk attitudes, confidence, and the Big Five personality traits. For most outcomes, the predictive power of competitiveness exceeds that of the other traits.

We develop a data-rich measure of expected macroeconomic skewness in the U.S. economy. Expected macroeconomic skewness is strongly procyclical, mainly reflects the cyclicality in the skewness of real variables, is highly correlated with the cross-sectional skewness of firm-level employment growth, and is distinct from financial market skewness. Revisions in expected skewness lead to business cycle fluctuations nearly indistinguishable from those induced by the main business cycle shock of Angeletos et al. (2020). This result is robust to controlling for macroeconomic volatility and uncertainty, and alternative macroeconomic shocks. Our findings suggest an important role of higher-order dynamics for business cycle theories.

This paper combines personnel records of the U.S. government with census data to study how exposure to greater female representation at work can persistently reduce intergenerational gender gaps in labor market outcomes. Exploiting city-by-department variation in the sudden expansion of female employment during World War I, we find that daughters of civil servants exposed to female co-workers are more likely to work later in life. This intergenerational effect operates through exposed fathers and extends beyond the public sector, reducing the earnings gap by 12%. Consistent with a broader shift in attitudes toward working women, exposure to female co–workers also made male civil servants more likely to marry working women. We show that cities exposed to larger increases in female federal workers saw persistently higher female labor force participation in both the public and the private sector. Increasing gender representation within the public sector can thus have broader labor market implications.

We study the intergenerational impact of birth-control policies on fertility and examine whether and how these policies reduce fertility, even after their abolition. We develop a model that integrates the endogenous evolution of fertility norms. Birth-control policies, through the reduction of mothers’ fertility, establish new norms that shape the fertility decisions of subsequent generations. Consequently, daughters’ fertility is lower due to these new norms, even when the policies are no longer in force. To test the model’s implications, we leverage a quasi-experimental setting provided by China’s One-Child Policy, which was implemented in a staggered manner starting in 1979 and gradually phased out beginning in 2014. Based on the recently released 2020 population census, our results reveal that the policy has an impact on reducing fertility and affects generations no longer subject to its regulations. This study is the first to provide causal evidence of birth-control policies from an intergenerational perspective and highlights the role of norms in shaping fertility outcomes.

We study the effect of risk on how firms organize their supply chains. We use transaction-level data on U.S. manufacturing imports to construct a novel measure of input sourcing risk based on the historical volatility of ocean shipping times. Our measure isolates the unexpected component of shipping times that is induced by weather conditions along more than 331,000 maritime routes. We first document that unexpected shipping delays significantly reduce importers’ sales, profits, and employment. We then show that firms actively diversify weather risk by using more routes and foreign suppliers, although their import values decline. To rationalize these findings, we introduce shipping time risk into a general equilibrium model of importing with firm heterogeneity. Our quantitative analysis predicts substantial costs for the U.S. economy associated with supply chain risk.

We provide the first estimates of intergenerational income mobility using tax data for a large developing country, namely Brazil. We measure formal income from tax and payroll data, and we train machine learning models on census and survey data to predict informal income. We quantify the estimation bias resulting from income imputation and other sources of measurement error, and show that such bias remains negligible in our context. A 10 percentile increase in parental income rank is associated on average with a 5.5 percentile increase in child income rank, with considerable variation across sociodemographic groups and geographical areas.

This paper connects changes in employer characteristics through job transitions to employee earnings following mergers and acquisitions. Using firm balance sheet data linked to individual earnings data in Canada and a matched difference-in-differences design, we find that earnings of workers at target firms decrease after M&As relative to control workers, largely driven by those who move to other firms. Workers leaving targets move to larger and more profitable firms, but still experience wage declines. These decreased earnings are also concentrated among workers with longer tenure. These results are consistent with workers losing valuable match-specific premia after M&A-induced job transitions.

This paper investigates the long-term impacts of China’s nationwide public health campaigns targeting malaria, measles, and meningitis between the 1960s and 1980s. Exploiting regional variation in precampaign disease prevalence across birth cohorts, we show that these interventions generated sizable improvements in education, cognition, health, and income. As an illustrative case, individuals from high-malaria regions who were fully exposed to the eradication campaign attained about 0.5 additional years of schooling and earned over 10% higher income in adulthood, with cognitive and schooling gains explaining a substantial share of the income effects. Extending the same approach to measles and meningitis vaccination campaigns reveals comparably large benefits, with internal rates of return ranging from 21% to 34%. Together, these findings highlight the lasting socioeconomic returns to early-life health interventions and underscore the role of public health as a foundation for human capital accumulation and long-run economic growth.

Market power is costly to build and, once established, is typically persistent and difficult to change. This paper investigates the impact of large economic shocks (serious epidemics) on the redistribution of market power in manufacturing industries. Using a model of firms’ dynamic decisions on production, pricing, and inventory holding, we demonstrate the importance of inventory stock and demand uncertainty in understanding market power and propose a new measure of market power. We find that the 2003 SARS shock in China significantly reduced the market power of firms in SARS-impacted areas. This effect is long lasting. SARS also substantially increased the inventory of affected firms, which partially contributed to the redistribution of market power.

Against a backdrop of sharply rising inequality, the Tokyo Round of the GATT resulted in a 1.6 percentage point reduction in average US tariffs – larger than CUSFTA, NAFTA, and the liberalization accompanying the granting of PNTR to China. We construct a novel IV based on the so-called “Swiss formula” that governed the Tokyo Round tariff liberalization to provide evidence of its effects on imports and inequality. Instrumented tariff reductions explain approximately 20% of the rise in income inequality between non-production and production workers between 1979 and 1988. This effect is largest among women, workers in routine occupations, and workers in more technology-intensive industries, suggesting a complementarity between trade liberalization and skill-biased technological change.

We examine firm responses to state hiring and investment subsidies. We leverage institutional features of the California Competes Tax Credit (CCTC), a large-scale business incentive program that incorporates best practices from prior job creation policies. The CCTC award selection procedure combines formula-based and discretionary components. Leveraging applicant score eligibility cutoffs in a regression discontinuity design and taking advantage of rich longitudinal microdata on establishments and their parent firms, we find that businesses expand employment in California in response to CCTC awards. There is little evidence that these expansions come at the expense of firms’ operations in other states. Our results suggest that targeted and audited hiring and investment subsidies can be effective in promoting local business expansions without inducing significant cross-state displacement effects.

We document that in response to intensified competition from China in the U.S., poor countries reduce their export prices relative to rich countries, consistent with conventional wisdom. Interestingly, however, the opposite is true for export quantities. To reconcile these facts, we develop and estimate a general equilibrium model of trade featuring (i) cross-country heterogeneity in the ability to produce high-quality goods and (ii) a two-dimensional Bertrand competition on price and quality. Our model explains the empirical facts by showing that rich countries have a comparative advantage in quality upgrading, whereas a nested model without quality cannot do so.

How do import tariffs affect employment? We develop an empirical strategy to identify the effects of tariffs using a difference-in-differences strategy, comparing antidumping (AD) investigations resulting in AD tariffs to those not resulting in AD tariffs. We find that an AD tariff decreases imports and increases employment in the protected sector. Moreover, employment in downstream firms decreases, while upstream firms are unaffected because the protected sector sources inputs abroad. Using a model to quantify the aggregate effects, we find that the Brazilian AD policy increased employment by 0.06% at a welfare loss of 2.4%.

This paper investigates fairness perceptions of extreme income inequality generated in winner-take-all competitions. Two large-scale experiments with more than 7,000 participants from the general population of the U.S. show that extreme earnings inequality is widely accepted, even when the winner only slightly outperforms the runner-up. The effect of the winning margin on inequality acceptance is modest compared to the effect of shifting the source of inequality from luck to winning by the smallest possible margin. The experimental choices are systematically associated with broader fairness attitudes and policy preferences, including support for higher taxation of top earners and redistributive economic policy.

Theory predicts that outsourcing public services to the private sector can reduce costs and improve efficiency, but can also induce cost-cutting and compromise quality. We assess the Brazilian “Organizações Sociais de Saude” model (OSS), which outsources management of public hospital services to the private sector while the state remains the residual claimant. We show that this enhances hospital production and operational efficiency without adverse effects on hospital quality and equity. Increased inpatient production addresses previously unmet demand, expanding local access to hospital care and reducing population mortality. Performance gains arise from improved operational efficiency achieved through increased hospital management capacity. This facilitates staffing adjustments, favoring higher-skilled personnel, dismissing lower-productivity staff, and adopting flexible, performance-tied employment contracts. Effects are larger among private organizations with more management experience, underscoring returns to managerial capacity. Our findings show that incentive-ownership structures can address the quantity-quality trade-off in public service delivery, even when contracts are incomplete and quality is hard to measure.

How does proximity to coworkers affect training and productivity? We study software engineers at a Fortune 500 firm from 2019 to 2024, leveraging two shocks to proximity: (i) the office closures in 2020 and (ii) the subsequent return-to-office mandates in 2022 and 2023. In both cases, co-located teams experienced bigger changes in proximity than distributed ones, facilitating difference-in-differences designs. We find that sitting near teammates increases coding feedback by 18.3% and improves code quality. Gains are concentrated among less-tenured and younger employees, who are building human capital. However, there is a tradeoff: experienced engineers write less code when sitting near teammates. In national US data, we find evidence that the rise of remote work has had scarring effects on young college graduates. In remotable jobs, young graduates’ unemployment rate increased relative to older graduates’ post-pandemic (2022−2024) compared to pre-pandemic (2017−2019), a pattern we do not observe in non-remotable jobs.

This paper explores whether and why a maternal child penalty to earnings would emerge even without changes in employment and hours worked. Using a matched event study design, we trace monthly changes in determinants of wages (job performance, human capital accumulation, and promotions). Data come from a usefully unusual setting with required multiyear employment and detailed personnel data: the US Marine Corps. Mothers’ job performance initially declines, and gaps in promotion grow through 24 months postbirth. Fathers’ physical fitness performance drops somewhat but recovers. These patterns lead mothers to earn relatively lower wages, even absent changes in employment postbirth.

We propose a quantitative spatial model featuring heterogeneous worker groups and their travel to consume nontradable goods and services. We consider the opening of the Downtown Line in Singapore, which connected regions where high-income households have residential amenities to where nontraded sectors are productive. Leveraging transit farecard data, we show that high-income workers saw large welfare gains but low-income workers gained little. Everyone enjoyed improved access to consumption opportunities, but low-income jobs in nontradables moved to less attractive workplaces. Abstracting from consumption travel understates the disparate impact across worker groups threefold.

Addressing climate change requires individual behavior change and voter support for pro-climate policies, yet surprisingly little is known about how to achieve these outcomes. In this paper, we estimate causal effects of additional education on pro-climate outcomes using new compulsory schooling law data across 20 European countries. We analyze effects on pro-climate beliefs and behaviors, as well as novel data on policy preferences and voting for green parties. Results show that a year of education substantially increases pro-climate beliefs, behaviors, and policy preferences.

This paper reports causal evidence on how the extent of hybrid work—the number of days worked from home relative to days worked from office—affects employee attitudes and performance. Workers who spent around two days in the office each week on average self-reported greater work-life balance, more job satisfaction, and lower isolation from colleagues compared to workers who spent more or fewer days in the office. Employees in the intermediate hybrid condition received no different performance ratings compared to peers who spent more or fewer days in the office.

We examine how the 1993 Family and Medical Leave Act (FMLA) impacts the gender composition at U.S. firms experiencing a negative demand shock. Combining changes in Chinese imports across industries between 2000 and 2003 and a sharp regression discontinuity to identify FMLA status, we find that an increase in import competition decreases the share of female employment, earnings, and promotions at FMLA relative to non-FMLA firms. This effect is driven by women in prime child-bearing ages and without college degrees and is pronounced at firms with all male managers. These results suggest that job-protected leave mandates may exacerbate gender inequalities in response to adverse shocks.

Exploiting a 1960s government trial in Copenhagen, we study the long-run effects of preventive health care for toddlers. We combine administrative data with handwritten nurse records to document universal treatment take-up. Treated children enjoy a five percent of a standard deviation increase in a good adult health index. While initial trial cohorts experience positive health and labour market impacts, those are absent for the final cohorts. Impacts are largest for children with initial health disadvantage and females, and we identify childhood health improvements as a core mechanism. The heterogeneity of trial effects across individuals’ initial health status and cohorts documents that universal toddler care can alleviate health inequalities at low costs, and that the counterfactual policy environment matters.

This paper investigates whether tax evasion opportunities can increase tax revenue. Past theoretical discussions have presented mixed outcomes as to whether allowing taxpayers to opt into uncertainty could indeed enhance overall tax revenues. In this study, we conducted a series of original real-effort experiments in an online setting with almost 6,000 participants to test this hypothesis empirically. Our findings show significant positive labour supply responses to the opportunity to evade (increased labour supply by 30%). More importantly, the expected tax revenue significantly and substantially increased by up to 40%. Strikingly, this effect persists when comparing effective tax rates: Lowering effective tax rates through probabilistic enforcement (the opportunity to evade) is more efficient than simply lowering statutory tax rates. Our findings suggest that the opportunity for tax evasion can increase tax revenues beyond what a corresponding decrease in nominal rates would achieve.

We study the relation between the presence of superstar firms and college students’ major choice. Occurrences of superstar performers in an industry are followed by a sharp rise in the number of college students choosing to major in related fields. This cohort effect remains significant after controlling for lagged industry returns and wages. Students’ tendency to follow superstars, however, is met with lower real wages earned by entry-level employees when these students enter the job market. Further evidence from two college-graduate surveys shows that such adverse career outcomes can last for decades.

International migrant workers are vulnerable to abuses by their employers. We implemented a randomized controlled trial of an intervention to reduce mistreatment of Filipino women working as domestic workers (DWs) by their household employers in Hong Kong and Saudi Arabia. The intervention --

Using machine learning and product-level data on single men’s and single women’s consumption patterns, we develop an index that quantifies the „gendered‟ nature of consumer goods. We use the index to investigate how gender-specific labour market shocks influence spending patterns within heterosexual households. Our findings reveal that industrial robot adoption, which worsened men’s relative economic position, shifted household consumption toward products predominantly purchased by single women. In contrast, the expansion of fracking, which boosted demand for young and less skilled men, yields suggestive but less robust evidence of increased spending on goods favoured by single men. Although neither shock significantly altered total spending on children’s products, robot exposure led to a reallocation of spending toward goods more commonly purchased for daughters than for sons.
