| Speaker & Title | Kurt Sweat (The University of Texas Southwestern) "Performance Monitoring and Certification Threats: Evidence from Organ Transplantation" with Itai Ashlagi and Hannah Bae |
| Abstract | Organ transplantation remains the best treatment for end-stage organ failure, but a shortage of organ donors and wastage of donated organs has contributed to growing organ transplant waitlists that result in excessive utilization of alternative treatments such as dialysis. Organ procurement organizations (OPOs) are responsible for identifying eligible donors, obtaining consent for donation, and coordinating the donation and recovery process while transplant centers (TCs) decide whether to accept or reject offers for transplantation on behalf of their patients. OPOs are subject to recently established performance metrics that they must meet to maintain their contract and oversee organ procurement in their designated region. This study investigates the impact of the newly established performance monitoring and recertification process on the supply and the recovery of organs for transplant in anticipation of the risk of future decertification. The number of donors and organs recovered for transplantation increased, particularly among OPOs classified as low-performing, following the release of the report. We find that this may be linked to the recovery of marginal organs from donors with relatively high health risks. However, organs from these donors typically go unused, as TCs become increasingly selective over offers as they receive more. The findings of this paper highlight the potential benefits of refining the current performance metrics to support ongoing quality improvements in the United States organ procurement and transplantation system. |

| Speaker & Title | Yun-Ting Yeh(University of Arizona) Adjustment Frictions and the Cost of Environmental Regulatory Uncertainty [Paper] |
| Abstract | When regulators are appointed by elected government officials, political power shifts create regulatory uncertainty through regulator turnover. Regulator turnover can change how rules are enforced, generating fluctuations in enforcement inten- sity for regulated facilities. Moreover, adjusting pollution levels in response to new enforcement regimes often involves adjustment costs. This paper quantifies the wel- fare cost of such regulatory fluctuations in California’s water quality enforcement, emphasizing the roles of adjustment costs and political inefficiency—that is, ineffi- ciencies stemming from politically driven variation in enforcement intensity. Using linked data on enforcement, compliance, and regulator membership, I show that facility violations gradually adjust following regulator turnover, consistent with ad- justment costs. Estimating a structural model of facility pollution decisions, I find substantial adjustment costs: past pollution influences abatement 3.5 times more than current fines, reflecting slow adjustments in abatement behavior. I estimate welfare losses equal to nearly one-third of total fines—28% from adjustment costs and 72% from political inefficiency—relative to a stable enforcement regime. While these adjustment costs raise costs for facilities, they also stabilize pollution out- comes by dampening responses to regulatory swings. However, uncertainty about future regimes weakens this stabilizing effect and amplifies adjustment costs. I further show that institutional stability improves welfare: doubling regulator term lengths to eight years reduces welfare losses by approximately half. |

| Speaker & Title | Atsushi Yamagishi (山岸敦) (Hitotsubashi University) "Urbanization without Industrialization: Evidence from US Bases in Okinawa" with Ikuto Aiba [Paper] |
| Abstract | We examine how the external consumption demand and employment shape the pattern of urbanization and the economic structure. We focus on the unique case of Okinawa in Japan, where many US military bases were constructed for strategic reasons and created substantial consumption demand and employment of local workers. Using newly digitized data, we first document rapid urbanization near the bases, driven by service sector expansion rather than manufacturing. We then develop a new quantitative spatial model and calibrate it to the Okinawan economy in 1970. Our counterfactual analysis highlights that the US-base sourced consumption and employment were crucial to urbanization without industrialization, which entailed large positive impacts on the aggregate income and welfare. |

| Speaker & Title | Elaine Meichen Liu (Georgia State University) "Externalities of Marijuana Legalization: Marijuana Use in Non-Legalizing States" [Paper] |
| Abstract | We study the impact of social media on marijuana use. Leveraging the Facebook Social Connectedness Index, which measures the strength of connectedness between geographic areas based on Facebook friendship ties, we explore the impact of connections to states where recreational marijuana use is legalized on marijuana use and workplace drug testing positivity rates in areas where marijuana remains illegal. The findings reveal that areas which are more connected to legalized states exhibit higher rates of marijuana use and workplace drug testing positivity even after controlling for geographic proximity to the legalized states. The results suggest that even connections beyond closed proximity can play a significant role in shaping individuals' behaviors. Our findings of the externality of legalization in one state to other more connected out-of-state areas imply that studies that estimate the impact of legalization using a standard difference-in-differences approach without taking into account the network underestimate the direct effect on the state that legalizes. |

| Speaker & Title | Guy Pincus (London Business School) Wildlife and Conflict: The Cost of Protecting Biodiversity |
| Abstract | Our planet is experiencing the first human-induced mass extinction of species. In response, policymakers have implemented international trade bans to preserve rare animals and forest species such as rhinos, elephants, and rosewood. Yet little research examines their consequences. Combining georeferenced habitat maps of wild animals and trees with armed conflict data, I uncover sizeable adverse effects of international trade ban treaties. First, event-study estimates reveal that bans raise the likelihood of conflict in habitat areas by about 40%. Two findings support a windfall-related conflict mechanism. For elephant ivory, a natural experiment shows that, in response to supply-side policies, prices change, which in turn changes the likelihood of conflict events in their habitat. Given the elephant’s broad habitat, the implied magnitude exceeds that of well-studied conflict minerals. For wild trees, satellite data show that harvesting shifts from high- to low-capacity states once bans are imposed, generating rents that spark violence. An analysis of battles’ locations before and after the policy reveals that militias and rebels expand into new, distant areas and are more likely to gain territorial control, consistent with a feasibility mechanism in which windfalls relax budget constraints. A quantitative model suggests that a targeted policy restricting trade in states with strong institutions and smaller wildlife stocks can conserve resources while limiting conflict. Given these spillovers, international trade bans, if maintained, should be accompanied by state-building support for low-income countries, which often lack enforcement capacity. |

| Speaker & Title | Sayantan Mitra (University of California, Berkeley) Who Benefits From Deforestation for Infrastructure? Evidence from India |
| Abstract | The trade-off between natural environmental resources and economic development has long been a subject of academic and policy concern. One such trade-off is related to the clearing of forests for infrastructure, which accounts for 10% of deforestation globally and 80% in India. In this paper, I estimate its local causal effects in India using a large household level panel. First, I find that indigenous tribal households, who face a negative shock to their consumption basket and productive inputs from forests, consume a higher proportion of their own agricultural produce and are less likely to engage in the sale of forest products. Second, only poorer households appear to experience significant rise in household incomes and consumption expenses along with a return of migrants. This seems to be driven by an increase in local engagement in trade while high-skilled employment declines, in line with the predictions of a standard Hecksher-Ohlin model of infrastructure reducing barriers to trade with a skill-abundant external economy. A back-of-the envelope calculation accounting for only the local environmental costs and the economic benefits to only local poorer households show that the benefits justify clearing forests for infrastructure only for small projects (<95 hectares) in densely populated areas (>25 households/sq. km). |

| Speaker & Title | Myoung-jae Lee (Korea University) "Causal Reduced Form is the Long-Awaited True Model" |
| Abstract | Causal Reduced Form (CRF) is an "outcome (Y) representation linear in treatment D", with a causal parameter of interest as the slope of D. CRF is (almost) model-free, and holds for any Y (binary, count, continuous,...). Diverse CRF's appeared for various types of D: binary exogenous, multiple exogenous, binary endogenous, network treatment, mediator, DiD, etc. CRF has three uses. Firstly, it reveals the restrictions embedded in commonly used structural forms. Secondly, being linear in D, it allows estimating the causal parameter with OLS, IVE or GMM. Thirdly, substituting the CRF into an estimator formula shows what the estimator actually estimates. As it turns out, minor variants of many OLS and IVE controlling D and covariates X are consistent to an "overlap-weighted" average of X-heterogeneous effects of D for any form of Y. |

| Speaker & Title | Cody Cook (Yale University) "Where to Build Affordable Housing? Evaluating the Tradeoffs of Location" with Pearl Z. Li, Ariel J. Binder [Slides] |
| Abstract | How does the location of affordable housing affect household welfare, the distribution of assistance, and broader societal objectives such as racial integration? Using administrative data on affordable housing tenants, we first show that, despite fixed eligibility requirements, developments in higher-opportunity neighborhoods disproportionally house tenants who are higher-income, more educated, grew up in richer families, less likely to have children, and far less likely to be Black or Hispanic. To quantify the welfare implications, we build and estimate a model in which households choose from both market-rate and affordable housing options, where the latter are rationed by private developers. While building affordable housing in higher-opportunity neighborhoods costs more, it also increases household welfare and reduces racial and economic segregation. However, the welfare gains accrue to more moderate-need and white (non-Hispanic) households at the expense of other households. This distributional shift is primarily due to crowding out: households that only apply for assistance in higher-opportunity neighborhoods crowd out those willing to apply regardless of location. Relative to the choice of location, other policy levers—such as lowering the income limits used for means-testing—have only limited effects. |

| Speaker & Title | Naila Shofia (National University of Singapore) "Wearing Your Religion: Evidence on Employers’ Preferences in Indonesia" |
| Abstract | In collaboration with one of Indonesia’s largest job portals, we examine the effect of displaying religious identity on labor market outcomes. Using a modified version of the Incentivized Resume Rating (IRR) method with over 1,200 real employers, we find that signaling religious identity reduces hiring outcomes across several dimensions, including the likelihood of being hired, the probability of being interviewed, and the salary offered. These penalties are similar in magnitude for male and female candidates and remain consistent across job levels, job types, gender-specific job requirements, and employer gender. Belief elicitation exercises reveal that candidates displaying religious attributes are perceived as more religious but are also rated lower on traits valued by employers. An additional experiment examining applicants’ second-order beliefs shows that jobseekers are not fully aware of the negative consequences associated with displaying religious identity. Notably, many female jobseekers believe that wearing a headscarf helps them avoid unwanted attention in the workplace, which may inform their decision to adopt such religious markers despite potential labor market penalties. |

| Speaker & Title | Pol Campos-Mercade (Lund University) "What Money Shouldn’t Buy? Measuring Aversion to Monetary Incentives for Health Behaviors" with Armando N. Meier, Florian H. Schneider and Roberto A. Weber |
| Abstract | We study attitudes toward offering monetary payments for vaccination. We develop the Policy Lab, an experimental paradigm to characterize policy preferences in which participants decide whether to implement actual interventions to influence others' real-world behavior. In two studies with representative samples of the Swedish population (N=2,010) and one with Swedish policymakers (N=2,008), participants decide whether to provide others (N=1,529) with monetary incentives for vaccination. A majority of participants oppose using monetary incentives. Despite the widespread perception that such incentives are an effective policy instrument, which is supported in our data, opposition to their use is driven by perceptions that they are coercive and unethical. Policymakers exhibit, if anything, greater opposition to the use of monetary incentives. We also document that opposition to incentives extends beyond vaccination to other health domains. Our study provides evidence that the public opposes policies that they correctly perceive as effective, potentially creating barriers to their adoption. We further introduce a novel method to elicit policy preferences, widely applicable whenever researchers conduct randomized trials. |

| Speaker & Title | Shyamal Chowdhury (Australian National University) "The Formation of Economic Preferences" [Slides] |
| Abstract | We use unique panel data on children’s economic preferences to study preference formation before the onset of adulthood. Our data encompass incentivized experiments eliciting time, risk, and social preferences as well as IQ tests with more than 4,500 children and adolescents aged 7-18 and their parents. We go beyond previous cross-sectional evidence by studying the dynamic, within-individual development of children’s preferences over time, demonstrating preference persistence already at young ages. Building on the model of skill formation (Cunha and Heckman 2007), we provide first evidence on self-productivity and cross-fertilization of children’s preferences and IQ. Moreover, we demonstrate that family members, parental investments, and local shocks are important sources of the substantial heterogeneity in children’s preference trajectories. Given the critical role of preferences and IQ in shaping behaviors and outcomes, our findings offer an explanation for social immobility. |

| Speaker & Title | Jong-Wha Lee (Korea University) "Impact of Retirement and Re-employment on the Health of Older Adults" with Do Won Kwak (Korea University) [Paper] |
| Abstract | Increasing life expectancy poses significant challenges to the employment and quality of life of older adults. This study examines the impact of retirement and re-employment on the health of older adults in Korea, utilizing longitudinal data from 2008 to 2020. We employ the instrumental variables method to estimate causal effects by leveraging variations in pension eligibility age and benefit amounts. The results reveal that retirement leads to a significant deterioration in health outcomes, including self-rated health, chronic diseases, and depression among older individuals. Conversely, re-employment after retirement is associated with a notable improvement in overall health. We find that retirement and re-employment influenced retirees’ health by changing their engagement in physical and social activities. These results suggest that policies encouraging late retirement or facilitating new employment opportunities and social activities post-retirement may mitigate or delay adverse health outcomes among older adults. |

| Speaker & Title | Dominic Rohner (Geneva Graduate Institute) "Who Wins Wars?" with Jonathan Federle and Moritz Schularick [Paper] |
| Abstract | Economic resources are often seen as decisive for the outcomes of military conflicts. This paper asks whether “deeper pockets” help win wars. We construct a fine-grained dataset covering more than 700 interstate disputes and rely on exogenous resource price shocks to estimate the causal effect of windfall gains on winning chances in interstate conflicts. We find a statistically significant and quantitatively large impact of windfall gains on winning odds and show that a key channel of transmission is a surge in military spending, after an exogenous increase in government revenues. |

(Hitotsubashi University) "The Impact of the Publication of School Test Scores on Housing Markets: Evidence from Japan" |
| Abstract | Identifying parents' willingness to pay for school quality is a significant issue. To estimate the magnitude, we focus on the setting of Japanese public elementary schools, which are highly uniform in terms of school inputs and operate under a distinctive disclosure policy. Although the disclosure of test scores at the school level had been strictly prohibited in Japan, the central government implemented a reform in 2014 that allows for the publication of results by school. Employing a boundary discontinuity design close to school district boundaries combined with a difference-in-differences model before and after publication, we find heterogeneous results by market that an increase of one standard deviation in total test score leads to increased sale prices of apartments by 2.0%--2.7% but to increases in rents of only 0.4%--0.6% after publication. Our extended analysis suggests that the effects are slightly larger for math and applied content test scores than for Japanese and basic content scores. |

| Speaker & Title | Suk Joon Son (The University of Tokyo) "The Effects of Free Subway Rides for Seniors and Welfare Implications" |
| Abstract | This paper evaluates the welfare consequences of granting older adults free subway access using a quasi-experimental age-cutoff policy in Korea and novel cellphone mobility data. The subsidy significantly increases subway use among seniors but has little effect on car travel. The policy is highly regressive, and evidence on health benefits is mixed. To capture spillovers from congestion and evaluate welfare under counterfactual policies, we estimate a transportation mode choice model, using the policy as an instrument. Simulations show that the current policy cannot be justified as optimal under any reasonable welfare weights or assumptions about uninternalized health benefits, with large welfare losses on other commuters through congestion. A budget-neutral alternative—providing equal discounts for subway and bus rides—improves equity and reduces welfare losses by 40%. |

| Speaker & Title | Joshua Gottlieb (University of Chicago) "Market Size and Trade in Medical Services" with Jonathan I. Dingel, Maya Lozinski, Pauline Mourot [Paper] |
| Abstract | We uncover substantial interregional trade in medical services and investigate whether regional increasing returns explain it. In Medicare data, one-fifth of production involves a doctor treating a patient from another region. Larger regions produce greater quantity, quality, and variety of medical services, which they “export” to patients from elsewhere, especially smaller regions. We show that these patterns reflect scale economies: greater demand enables larger regions to improve quality, so they attract patients from elsewhere. Despite concerns about rural access, larger regions have higher marginal returns to spending. We study counterfactual policies that would lower travel costs rather than relocating production. |

| Speaker & Title | Rajeev Dehejia (New York University) "Malleable minds: The effects of STEM v. humanities-focused curricula" joint with Robert Ainsworth, Andrei Munteanu Cristian Pop-Eleches, Miguel Urquiola |
| Abstract | We examine the impact of assignment to STEM v. humanities-focused curricula in Romania’s high school system. We apply a regression discontinuity design to administrative and survey data to estimate effects on educational pathways, career plans, and non-cognitive outcomes. An overarching theme of our findings is the malleability of students to what they study. Assignment to STEM increases STEM college enrollment by 23 pp and STEM career intentions by 17 pp, with corresponding negative effects on humanities-related enrollment and career plans. Exploring mechanisms, we find that STEM assignment changes students’ self-perceived academic abilities and their preferences over academic subjects and job tasks. We find less evidence for stories related to sunk costs, peer and teacher influences, or beliefs about earnings and work conditions. Importantly, STEM assignment involves a risk: it improves wellbeing, high school satisfaction, and career prospects on average, but reduces performance on a high school exit exam, leading to lower college enrollment and retrospective satisfaction among low-achieving students. Similarly, it makes female students report negative experiences with college professors and peers. A final finding is that male students become more conservative. We provide suggestive explanations for our results on wellbeing and political preferences by measuring effects on time use, friendships, and expectations. |

| Speaker & Title | Timothy Halliday (University of Hawaii at Manoa) "Genetic Predictors of Cognitive Decline and Labor Market Exit" joint with Anne Katrine Borgbjerg, Esben Agerbo, Nabanita Datta Gupta [Paper] |
| Abstract | We analyze administrative and genetic data from over 200,000 Danes to study the effects of genetic risk for Alzheimer’s Disease (AD) on labor market outcomes. Higher AD genetic risk increases dementia diagnoses and GP visits for both genders. Among women aged 45–65, it reduces labor participation and raises disability pension uptake, especially near retirement. These effects weaken for women with high polygenic scores for education. For men, AD genetic risk shows no employment impact. These gender differences align with evidence that AD genetic markers are more predictive in women. |

| Speaker & Title | Kohei Kawaguchi (The Hong Kong University of Science and Technology, HKUST) "Employers' Unilateral Settlement of Dismissal Disputes" |
| Abstract | We analyze the implications of introducing legally binding unilateral settlement options for employers in dismissal disputes through a model of employment adjustment with bargaining under litigation threat. Contrary to concerns, our model shows that unilateral settlement can reduce inefficient adjustments and enhance the surplus of moderately productive workers when adjustments do not significantly hurt productivity. While employers can avoid litigation costs through unilateral settlement, they must forgo potential worker output, which in turn strengthens workers' bargaining positions. Well-designed unilateral settlement institutions can therefore promote stable employment, efficiency, and distributional equity, particularly benefiting moderately productive workers beyond mere litigation cost savings. |

| Speaker & Title | Stephan Litschig (National Graduate Institute for Policy Studies, GRIPS) "Weighted Subgroup Analysis" |
| Abstract | Subgroup analyses to explore mechanisms and conduct falsification tests are frequently used in research designs that require control variables for identification. However, given existing methods and typically available sample sizes it is difficult to account for other differences across subgroups beyond the characteristic of interest without imposing additional assumptions. As a result, evidence of subgroup effect heterogeneity - or lack thereof - is often difficult to interpret. This paper introduces a new approach to conduct subgroup analysis based on inverse probability weighting that allows holding other observable characteristics constant. Observations from subgroup zero with high (low) estimated probability scores to belong to subgroup one are up-weighted (down-weighted). Successful balancing of observables across subgroups helps to isolate effect heterogeneity due to the subgroup characteristic of interest from effect heterogeneity driven by observed confounders. The approach is illustrated with data from two studies that use subgroup analysis to explore a particular mechanism (Fujiwara 2015) or run a falsification exercise (Solis 2017). |

| Speaker & Title | Ayako Kondo (The University of Tokyo) "Parental Earnings Trajectories Around Childbirth in Japan: Evidence from Local Tax Records" with Taiyo Fukai |
| Abstract | This study examines the impact of childbirth on parental earnings in Japan, using newly available local tax records from multiple municipalities. By applying an event study specification, we estimate the "child penalty"—the percentage reduction in women's income relative to men's after childbirth. Our results reveal that women’s income declines by 60–80\% immediately after childbirth and remaining 50\% below pre-childbirth levels even four years postpartum, while men experience modest income growth. Moreover, the study also identifies significant heterogeneity in income trajectories, particularly among higher-earning women, some of whom recover their earnings close to their pre-birth levels, whereas others earnings remain significantly below pre-birth levels. Additionally, women with pre-birth earnings lower than the median tend to exit the workforce or adjust their income below the threshold for dependent spouses. |

| Speaker & Title | Abu Shonchoy (Florida International University) "Barriers to Labor Migration for the Rural Poor" |
| Abstract | Migration could be an important anti-poverty measure – allowing unemployed rural poor to spatially reallocate to areas where employment opportunities are promising. However, job-related rural-to-urban migration by the poor in developing countries is surprisingly limited. This raises important academic and policy-relevant questions: why do the poor fail to take advantage of these growing opportunities in urban job locations, and what are the barriers to skill migration? We introduce a vocational training "plus" program facilitating apparel sector employment for the poor rural youth in northern Bangladesh, where we relax some of the migration-related constraints in a rigorous Randomized Control Trial (RCT) setting. Data from the follow-up surveys—--six and eighteen months after the intervention—--show statistically significant, persistent, and large effects of the training program on migration and employment when complemented with stipend and/or paid internship components. Treated participants show substantial income and remittance impacts, especially during the time of a seasonal shock, as well as a reduction in income poverty, both for the stipend and internship treatment arms. Reduction in job search cost and migration financing are key mechanisms underlying the treatment effects. The benefit-cost ratio for the internship is estimated to be 8.85, indicating that the program can be scaled up cost-effectively. |

| Speaker & Title | |
| Abstract | We develop and estimate a new dynamic game of state fiscal policies under partisan governments. In our model policy-makers' preferences over expen ditures and taxes systematically vary by party affiliation and are subject to idiosyncratic shocks which reflect differences over policy within a party. The state government faces a binding ex-ante balanced budget constraint. Hence, taxes are a function of expenditures as well as the business cycle. We also account for adjustment costs that arise due to institutional constraints in the budget process and political gridlock. Our estimation approach exploits first order conditions that optimal expenditures must satisfy along the equilibrium path. It also exploits a forward simulation algorithm to compute the value functions and their derivatives based on the estimated policy functions. We estimate the model using a panel of 45 states during the past three decades. Our empirical results provide new insights into the systematic effects of partisan government on state fiscal policies. Our results suggest that adjustment costs are large and primarily reflect institutional constraints on the budget process. It takes up to eight years to adjust expenditures from one party’s bliss point to the other party's bliss point. Our policy counterfactuals suggest that the impact of increased polarization on the volatility of expenditures may be dampened by institutional constraints. |

| Speaker & Title | Takeaki Sunada (University of Rochester) "Peak-Load Pricing in Platform Markets" [Paper] |
| Abstract | We study welfare and profit impacts of peak-load pricing in the context of a dining reservation platform that allows restaurants to set variable prices. Using unique data on reservations and a measure of restaurant traffic, we estimate a model where equilibrium prices respond to both time-varying consumer price sensitivity and restaurants' capacity constraints. We find peak-load pricing, rather than intertemporal price discrimination, is the primary driver behind the observed price variation. We show that variable pricing increases social welfare by 8.6%, demonstrating the vital role of pricing in improving efficiency in the context of platform markets. We also find variable pricing can reduce the profit of the platform, which thus might lack the incentive to provide the variable-pricing technology despite its welfare benefits. Notably, this supply-side incentive misalignment is most salient when the platform and firms share their joint profit, thus offsetting the relative efficiency of profit-sharing contracts over per-unit-fee contracts. |

| Speaker & Title | Dan Han (the Lee Kuan Yew School of Public Policy at the National University of Singapore
) "Better Together? The Impact of Multi-State Purchasing Pools on Medicaid Drug Spending and Utilization" |
| Abstract | We study the effects of multi-state purchasing pools for Medicaid prescription drugs on rebates, drug utilization, and payment rates. These purchasing pools leverage bulk purchasing and preferred drug lists to increase states' bargaining power in negotiating supplemental rebates with drug manufacturers. Since 2003, more than 30 states have joined one of the three Medicaid-focused purchasing pools. Using data from the Medicaid Budget & Expenditure System and State Drug Utilization Data, we find that entering a purchasing pool increases the probability of a state collecting supplemental rebates and the size of those rebates. On the intensive margin, a larger pool size is associated with higher rebate amounts for existing pool members. Purchasing pool participation also increases generic drug utilization while reducing Medicaid payment rates for both branded and generic drugs. Taken together, our findings suggest that both combined volume and negotiation, as well as access to pricing information, may be at play in driving these effects. |

| Speaker & Title | Uta Schönberg (the University of Hong Kong) "Family-Friendly Workplace Policies" joint work with Julian Costas-Fernandez, Sebastian Findeisen, and Anna Raute |
| Abstract | The literature has studied the willingness to pay for family-friendly amenities, but less is known about the incentives for firms to provide these amenities. This paper examines the incentives for firms to offer family-friendly workplace policies, with a focus on firm-provided childcare. Drawing on German matched employer-employee data, combined with detailed survey panel data on firms, we find that firm-provided childcare enhances retention and reduces labor market breaks for mothers, especially for those in high-wage occupations. It also contributes to employment growth, which is disproportionately driven by firms that attract female talent. These findings can be rationalized through a stylized model of imperfect competition in the labor market, where family-friendly workplace policies are modelled as an amenity with direct production benefits. |

| Speaker & Title | Juan Pantano (the University of Hong Kong) "Stochastic Compliance and Identification of Treatment Effects" with Hidehiko Ichimura |
| Abstract | The exclusion restriction plays a key role in the identification of LATE (Imbens & Angrist (1994), Angrist, Imbens & Rubin (1996)). We discuss a particularly ubiquitous way in which the exclusion restriction would seem to be generically violated. We argue that this form of violation is not addressed in the many applications that rely on this influential framework. We characterize the bias that this particular violation gives rise to and, more constructively, discuss how to use the particular structure of the violation along with milder assumptions and additional data to restore identification. We provide sharper bounds by exploiting the specific structure of the exclusion restriction violation we uncover. Further, with an additional assumption which is plausible in many empirical settings, we restore point identification of LATE. We illustrate with examples and discuss why this violation is likely present in most existing empirical applications. We discuss how our arguments naturally extend to other IV settings where the LATE parameter is commonly invoked, such as randomized controlled trials with imperfect compliance and fuzzy regression discontinuity designs. Moving beyond LATE, we also consider how the same problems and solution ideas apply to identification of the MTE profile and more structural "Roy" models of treatment effects. |

| Speaker & Title | Daniel Waldinger (New York University) "Designing Dynamic Reassignment Mechanisms: Evidence from GP Allocation" with Ingrid Huitfeldt, Victoria Marone [Paper] |
| Abstract | We study the problem of designing a dynamic reassignment mechanism when agents' preferences over objects change over time. In the context of Norway's system for (re)assigning patients to general practitioners (GPs), we provide direct evidence of misallocation under the current mechanism—patients waiting for each others' GPs, but who cannot trade—and estimate a structural model of GP switching behavior to evaluate alternatives. Introducing Top Trading Cycles (TTC) would, on average, reduce waiting times and increase patient welfare. However, patients endowed with less desirable GPs would be harmed. Prioritizing these patients can avoid these harms while preserving most of the gains from TTC. |

| Speaker & Title | Arvind Magesan (University of Calgary) "Do Parties and Voters Disagree? An Equilibrium Analysis of Candidate Selection in India" |
| Abstract | We study how parties choose candidates, a key issue to understand political selection and ultimately policy choices. Do parties select candidates that voters like, or are their choices shaped by other considerations? What is the impact of policies that limit parties' choice sets, such as restrictions on candidates with a criminal history? To study these questions, we combine rich candidate-level data from India with a model in which parties trade off the electoral appeal of candidates against internal party preferences in a strategic game of candidate selection. We find that parties' preferences systematically deviate from voters'. While parties select candidates who are likely to win, all else equal they prefer those who are not overly popular. Selection decisions are also driven by strategic considerations, as well as factors that are independent of voter preferences, such as the ease of recruiting certain candidates. Our estimates provide a nuanced explanation for parties' motivation to run criminal candidates, and, through counterfactual simulations, shed light on the potential impacts of banning criminals from contesting elections. |

| Abstract | Firm innovation is expected to be a key driver of productivity growth, while it is often perceived as a threat to employment stability. We develop a framework to quantify the general equilibrium effects of process and product innovation on output and employment at the firm and aggregate levels. We construct measures of process and product innovation from patent data and use these measures to estimate production and demand functions for a panel of firms in several European countries. Our preliminary results suggest that both process and product innovation contribute to increases in output, employment, and labor productivity between 1995 and 2015. |

| Speaker & Title | Jackson Dorsey (University of Texas at Austin) "How Firms Cut Carbon: Evidence from the European Emissions Market" with R. Andrew Butters, Ivan Rudik |
| Abstract | Europe's industrial emissions fell by over 30% during the first 16 years of the EU Emissions Trading System (EU ETS), despite limited evidence of job or output losses. We investigate this decline using firm-level data and a flexible production model that treats emissions as a costly input. Estimated substitution elasticities between emissions and other inputs are low, suggesting limited abatement occurred via marginal input adjustments. Instead, emissions intensity declined primarily through clean, factor-augmenting technology—improving by over 50% from 2005 to 2021. Counterfactual simulations show that, holding technology constant, carbon pricing reduces emissions by shifting output toward cleaner firms but leads to lower overall output and employment in regulated sectors. Improvements in clean technology mitigate these e!ects by lowering production costs, highlighting how clean technological progress can ease the short-run economic burden of carbon pricing. |

| Speaker & Title | Ahmed Khwaja (University of Cambridge) "The Value of Pharmaceutical Alliances in FDA Approvals: Estimating A Semi-parametric Two-Sided Matching Model of Alliance Formation and Innovation" joint with Rebeca Mendez-Duron and Liang Zhao |
| Abstract | We estimate the value and synergies of pharmaceutical alliances for FDA approvals with a two-sided matching model of endogenous alliance formation in equilibrium using a semi-parametric maximum score estimator framework. We extend the literature by (1) allowing firms to "go-it-alone," thereby recovering the value of partner-specific characteristics necessary to compute an alliance's (total) value, and (2) estimating an alliance’s value for an outcome, i.e., new product development. Using data on 4,225 clinical trials between 2000 and 2011 by 744 firms, we find that more valuable alliances (ceteris paribus) comprise a firm with a partner that has: (i) greater experience working in alliances, and synergies from such experience, (ii) broader (narrower) scope of experience with diseases, the narrower (broader) the primary firm's such experience, and (iii) narrower scope of experience with drug classes (e.g., organic compounds), and synergies from such experience. Thus, a potential partner's experience with alliances should be a critical consideration in forming an alliance. Consequently, alliance experience per se can be a strategic investment that confers a competitive advantage for firms seeking alliances. Our procedure has a microfoundation interpretation in the Heckman (1979) selection framework and wider applicability to other two-sided settings (e.g., digital platforms, co-branding, etc.). |

| Speaker & Title | Tim Ruberg (The University of Tokyo) with Hideo Akabayashi (Keio University) "Moral Education and Child Development: A Randomized Controlled Trial in Japan" |
| Abstract | Pressure to perform, course overload, peer pressure, and bullying are some of the hardships many Japanese children face at school, potentially hindering their cognitive and non-cognitive skills development. We conduct an online randomized controlled trial aiming to mitigate these adverse effects by promoting self-confidence, self-control, well-being, and a satisfying school and social life. Our six-week, home-based program utilizes a dual approach: educating parents via weekly emails about their child's potential challenges and providing age-appropriate videos to their children. The videos are based on official moral education textbooks, ensuring alignment with national educational standards. The treatment is further divided into four arms differentiated by the video narrator. In addition to evaluating the effectiveness of the narrator, we analyze the impact of this low cost and highly scalable intervention on children's non-cognitive measures shortly after the conclusion of the program and in the long run, approximately half a year later, with the potential for further data collection. |

| Speaker & Title | Michael Dinerstein (Duke University) "Student Loan Forgiveness" with Samuel Earnest, Dmitri Koustas, Constantine Yannelis |
| Abstract | Student loan forgiveness has been proposed as a meanstoalleviate soaring student loan burdens. This paper uses administrative credit bureau data to study the distributional, consumption, borrowing, and employment effects of the largest event of student loan forgiveness in history. Beginning in March 2021, the United States federal government ordered $132 billion in student loans cancelled, or 7.8% of the total $1.7 trillion in outstanding student debt. We estimate that forgiven borrowers’ predicted monthly earnings were $115 higher than borrowers who did not receive forgiveness and $193 more than the general population. We find that student loan forgiveness led to increases in mortgage, auto, and credit card debt by 9 cents for every dollar forgiven. Borrowers’ monthly earnings and employment fell, at increasing rates for each month post forgiveness. The implied Marginal Propensities for Consumption (MPC) and Earnings (MPE) are 0.27 and-0.49, respectively. |
