    Immigration is often blamed for increasing unemployment among local workers. However, standard models, such as the neoclassical model and the Diamond-Mortensen-Pissarides matching model, inherently assume that immigrants are absorbed into the labor market without affecting local unemployment. This paper presents a more general model of migration that allows for the possibility that not only the wages but also the unemployment rate of local workers may be affected by the arrival of newcomers. This extension is essential to capture the full range of potential impacts of labor migration on labor markets. The model blends a matching framework with job rationing. In it, the arrival of new workers can raise the unemployment rate among local workers, particularly in a depressed labor market where job opportunities are limited. On the positive side, in-migration helps firms fill vacancies more easily, boosting their profits. The overall impact of in-migration on local welfare varies with labor market conditions: in-migration reduces welfare when the labor market is inefficiently slack, but it enhances welfare when the labor market is inefficiently tight

    We reproduced West (2024) "Formal designation of Brazilian indigenous lands linked to small but consistent reductions in deforestation," which investigates the impact of formally recognizing Indigenous Lands (ILs) on deforestation rates in Brazil from 1986 to 2021. The original study uses a quasi-experimental design, employing temporal and sectional matching methods to compare deforestation rates before and after IL designation, concluding an average reduction of -0.05% in deforestation. To verify these findings, we conducted three main tests: a logit analysis, the consideration of negative deforestation values in the Atlantic Forest, and the synthetic control method. The logit analysis assessed the relationship between IL designation and covariates like land size, elevation, slope, and proximity to urban centers, confirming that these factors significantly influence IL designation, consistent with the original study. We also examined the treatment of negative deforestation values in the Atlantic Forest, originally treated as zero. By retaining these values, we found no significant impact on the study's overall results, indicating that the original methodological choice did not affect the main conclusions. Finally, the synthetic control method was used to replicate the counterfactual analysis of IL-designated areas, demonstrating that these areas consistently exhibited lower deforestation rates compared to the synthetic control post-2011. These tests confirmed the original study's findings, demonstrating that the formal designation of ILs contributes to small but significant reductions in deforestation, supporting the effectiveness of ILs as a strategy for environmental conservation and indigenous rights protection. The reproducibility of these results reinforces the study's conclusions.

    This paper develops a large-scale algorithm‑based application to improve the match quality in the labor market. We use comprehensive administrative data on employment biographies in Germany to predict job match quality in terms of job stability and wages. The models are estimated with both machine learning (ML) (i.e., XGBoost) and common statistical methods (i.e., OLS, logit). Compared to the latter approach, we find that XGBoost performs better for pattern recognition, analyzes large amounts of data in an efficient way and minimizes the prediction error in the application. Finally, we combine our results with algorithms that optimize matching probability to provide a ranked list of job recommendations based on individual characteristics for each job seeker. This application could support caseworkers and job seekers in expanding their job search strategy. Dieses Papier beschäftigt sich mit einer groß angelegten Datenanalyse um die Matching-Qualität auf dem Arbeitsmarkt zu untersuchen. Hierfür verwenden wir einen sehr umfangreichen administrativen Datensatz zu Arbeitsmarktbiographien in Deutschland. Die Schätzungen werden sowohl mit maschinellem Lernen (extreme gradient boosting), als auch mit traditionellen statistischen Methoden (OLS, logit) durchgeführt. Bei der Gegenüberstellung beider Methoden wird deutlich, dass maschinelles Lernen insbesondere in den Bereichen Mustererkennung, Analyse von sehr großen Datensätzen und Minimierung der Fehlerrate deutliche Vorteile gegenüber den herkömmlichen Methoden aufweist. Schließlich werden die Prognosen für Matching‑Qualität (Stabilität und Löhne) mit Matching‑Wahrscheinlichkeiten kombiniert. Anhand dieser Ergebnisse wird für jede arbeitssuchende Person eine Liste mit Berufsvorschlägen generiert. Damit können Arbeitsvermittlern und Arbeitssuchenden Alternativen aufgezeigt werden, wodurch sich ihr Suchverhalten auf dem Arbeitsmarkt erweitern könnte.

    A growing number of central authorities use assignment mechanisms to allocate students to schools in a way that reflects student preferences and school priorities. However, most real-world mechanisms incentivize students to strategically misreport their preferences. In this paper, we provide an approach for identifying the causal effects of school assignment on future outcomes that accounts for strategic misreporting. Misreporting may invalidate existing point-identification approaches, and we derive sharp bounds for causal effects that are robust to strategic behavior. Our approach applies to any mechanism as long as there exist placement scores and cutoffs that characterize that mechanism's allocation rule. We use data from a deferred acceptance mechanism that assigns students to more than 1,000 university-major combinations in Chile. Matching theory predicts that students' behavior in Chile should be strategic because they can list only up to eight options, and we find empirical evidence consistent with such behavior. Our bounds are informative enough to reveal significant heterogeneity in graduation success with respect to preferences and school assignment

    This paper builds, identifies and estimates a model of the labor market that features strategic interactions in wage setting and two-sided heterogeneity in order to shed light on the sources of wage inequality. We provide a tractable characterization of the model equilibrium and demonstrate its existence and uniqueness. This characterization of the equilibrium allows us to derive a rich set of comparative statics and to gauge the relative contributions of worker skill, preference for amenities and strategic interactions to equilibrium wage inequality. Using instrumental variables, we establish identification of labor demand and supply parameters and estimate them using matched employer-employee data from Denmark. Using our estimated structural model, we perform a series of counterfactual analyses in order to provide a quantitative evaluation of the main sources of wage inequality in Denmark

    I study a central authority's ability to commit to a publicly announced mechanism in a one-to-one agent-object matching model. The authority announces a strategy-proof mechanism and then privately selects a mechanism to initiate a matching. An agent's observation in form of the final matching has an innocent explanation (Akbarpour and Li, 2020), if given the agent's reported preferences, there is a combination with other agents' preferences leading to an identical observation under the announced mechanism. The authority can only commit up to safe deviations (Akbarpour and Li, 2020)-mechanisms that produce only observations with innocent explanations. For efficient or stable announcements, I show that no safe deviation exists if and only if the announced mechanism is dictatorial. I establish that the Deferred Acceptance (DA) Mechanism (Gale and Shapley, 1962) implies commitment to stability. Finally, I show that group strategy-proof and efficient announcements allow commitment to efficiency only if they are dictatorial.

    This paper shows the importance of technological synergies among heterogeneous firms for aggregate fluctuations. First, we document six novel empirical facts using microdata that suggest the existence of important technological synergies between trading firms, the presence of positive assortative matching among firms, and their evolution during the business cycle. Next, we embed technological synergies in a general equilibrium model calibrated on firm-level data. We show that frictions in forming trading relationships and separation costs explain imperfect sorting between firms in equilibrium. In particular, an increase in the volatility of idiosyncratic productivity shocks significantly decreases aggregate output without resorting to non-convex adjustment costs

    Economists have long hypothesized that large and thick labor markets facilitate the matching between workers and firms. We use administrative data from the LEHD to compare the job search outcomes of workers originally in large and small markets who lost their jobs due to a firm closure. We define a labor market as the Commuting Zone*industry pair in the quarter before the closure. To account for the possible sorting of high-quality workers into larger markets, the effect of market size is identified by comparing workers in large and small markets within the same CZ, conditional on workers fixed effects. In the six quarters before their firm's closure, workers in small and large markets have a similar probability of employment and quarterly earnings. Following the closure, workers in larger markets experience significantly shorter non-employment spells and smaller earning losses than workers in smaller markets, indicating that larger markets partially insure workers against idiosyncratic employment shocks. A 1 percent increase in market size results in a 0.014 and 0.023 percentage points increase in the 1-year re-employment probability of high school and college graduates, respectively. Displaced workers in larger markets also experience a significantly lower need for relocation to a different CZ. Conditional on finding a new job, the quality of the new worker-firm match is higher in larger markets, as proxied by a higher probability that the new match lasts more than one year; the new industry is the same as the old one; and the new industry is a "good fit" for the worker's college major. Consistent with the notion that market size should be particularly consequential for more specialized workers, we find that the effects are larger in industries where human capital is more specialized and less portable. Our findings may help explain the geographical agglomeration of industries--especially those that make intensive use of highly specialized workers--and validate one of the mechanisms that urban economists have proposed for the existence of agglomeration economies

    A classic trade-off that school districts face when deciding which matching algorithm to use is that it is not possible to always respect both priorities and preferences. The student-proposing deferred acceptance algorithm (DA) respects priorities but can lead to inefficient allocations. We identify a new condition on school choice markets under which DA is efficient. Our condition generalizes earlier conditions by placing restrictions on how preferences and priorities relate to one another only on the parts that are relevant for the assignment. Whenever there is a unique allocation that respects priorities, our condition captures all the environments for which DA is efficient. We show through stylized examples and simulations that our condition significantly expands the range of known environments for which DA is efficient. We also discuss how our condition sheds light on existing empirical findings.

    We approach the design of anti-discriminatory labor market regulation as a delegation problem. A private firm (the agent) is repeatedly faced with the opportunity of hiring one among several applicants to fill its vacancies. The firm is biased against applicants from some demographic group, and it is neutral towards applicants from some other group. Applicants differ not only with respect to their demographic characteristics, but also with respect to the idiosyncratic quality of their match with firm. A benevolent and unbiased labor market authority (the principal) enacts a hiring regulation (a direct-revelation mechanism without transfers) in order to reduce the impact of the firm's bias on its hiring behavior. The hiring regulation is constrained by the fact that the quality of the match between any particular applicant and the firm is privately observed by the firm. We characterize the optimal mechanism

    How does the presence of risk sharing affect sorting patterns on productive attributes when there are complementarities among partners' skills in match output? We develop a matching model in which risk-averse agents, who differ in skills, match pairwise for productive purposes. Match output has stochastic returns and matched partners efficiently share this risk. We find that under plausible assumptions the risk-sharing benefit of marriage tends to push toward negative sorting on partners' skills. To obtain the prediction of positive skill sorting--a robust empirical feature of marriage markets--this force needs to be counteracted by sufficiently strong skill complementarities in match output. We provide a novel inequality that characterizes monotone (positive or negative) equilibrium sorting, balancing out skill complementarities and risk-sharing considerations in the right way. Several classes of primitives (utility and match output functions) render monotone sorting optimal. We then highlight a new implication of positive sorting on exogenous skills for matching patterns on endogenous differences in risk aversion: Positive sorting on skills translates into positive sorting on risk aversion--in line with the evidence from marriage markets

    Despite substantial efforts to help consumers search in more intuitive ways, text search remains the predominant tool for product discovery online. In this paper, we explore the effects of visual and textual cues for search refinement on consumer search and purchasing behavior. We collaborate with one of the largest e-commerce platforms in China and study its roll out of a new search tool. When a customer searches for a general term (e.g., “headphones”), the tool suggests refined queries (e.g., “bluetooth headphones” or “noise-canceling headphones”) with the help of images and texts. The search tool was rolled out with a long-run experiment, which allows us to measure its short-run and long-run effects. We find that, although there was no immediate effect on orders or total expenditures, the search tool changed customers’ search and purchasing behavior in the long-run. Customers with access to the new tool eventually increased orders and expenditures compared to those in the control group, especially for non top-selling products. The purchase increase comes from more effective searches, rather than an increase in activity on the platform. We also find that the effect is not only driven by the direct value of suggested searches, but also by customers indirectly learning to perform more effective searches on their own.

    This paper presents the first empirical evidence of interdependent values and strategic responses by market participants in a two-sided matching market. We consider the market for medical school programs in Denmark, which uses a centralized assignment mechanism. Leveraging unique administrative data and an information experiment, we show that students and rival programs hold payoff-relevant information that each program could use to admit students with higher persistence rates. Programs respond to these two sources of interdependent values, student self-selection and interdependent program values, by exhibiting "home bias" towards local applicants. We construct and estimate a novel equilibrium model reflecting this evidence, and find that fully sharing information could significantly increase student persistence and program payoffs, but enabling students to communicate first preferences would leave outcomes unchanged. An alternative model assuming independent private values contradicts the empirical evidence, highlighting the importance of accounting for interdependent values in understanding and designing matching markets

    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 skills and job skill requirements, which determine match feasibility; (ii) technology, which determines the returns to matching; and (iii) idiosyncratic matching frictions, which capture the role of nonproductive worker and job traits in the matching process. The estimated model delivers two key insights. First, improvements in worker-job matching due to reduced matching frictions account for only a small share of cross-country income differences. Second, however, improved worker-job matching is crucial for unlocking the gains from economic development generated by adopting frontier endowments and technology
