Item type: Item , Policymaking, trust, and the demand for public services: evidence from a mass sterilization campaign(American Economic Association, 2025) León-Ciliotta, Gianmarco; Zejcirovic, Dijana; Fernández Bazán, FernandoWe study a large-scale family planning intervention in which more than 260,000 Peruvian women were sterilized. Many of these medical procedures are alleged to have been performed without patient consent. The subsequent disclosure of alleged illegal sterilizations caused reductions in the usage of contraceptive methods and prenatal and birth delivery services and, more generally, the demand for medical services in affected areas. As a result, child health worsened. The results persist for at least 17 years after the information disclosure and are driven by disappointed supporters of the implementing government. Learning about the government's malpractices undermined trust in institutions.Item type: Item , Promotions and productivity: the role of meritocracy and pay progression in the public sector(American Economic Association, 2025) Deserranno, Erika; Kastrau, Philipp; León-Ciliotta, GianmarcoWe study promotion incentives in the public sector. In collaboration with Sierra Leone's Ministry of Health, we introduce exogenous variation in the meritocratic nature of promotions from health worker to supervisor positions and in health workers' perceptions of pay progression upon promotion. Ten months later, our findings reveal that meritocracy leads to a 22 percent increase in health workers' productivity. Greater perceived pay progression in a meritocratic system boosts productivity by 23 percent, whereas in a less meritocratic system, it decreases productivity by 27 percent. We show that this reduction is consistent with a negative morale effect.
Item type: Item , The allocation of incentives in multilayered organizations: evidence from a community health program in Sierra Leone(University of Chicago Press, 2025) Deserranno, Erika; Caria, Stefano; Kastrau, Philipp; León-Ciliotta, GianmarcoDoes the allocation of incentives across the hierarchy of an organization matter for its performance? In an experiment with a large public health organization, we find that health care provision is highly affected by how incentives are allocated between frontline workers and their supervisors. Sharing incentives equally between these two layers raises health visits by 61% compared with unilateral allocations and uniquely improves health service provision and health outcomes. We provide reduced-form and structural evidence that effort complementarities and contractual frictions drive these results and explore the implications for the optimal design of incentive policies in multilayered organizations.Item type: Item , Post-COVID-19 condition patients' utilisation of healthcare resources after implementation of an integrated care unit(Springer, 2025) Vicente-Gómez, José Ángel; Muniategui Climente, Martín; Loste, Cora; Barreales, Saúl; Ricou Ríos, Laura; Paredes, Roger; Mateu, Lourdes; López Seguí, Francesc, 1991-Background: The economic effects of post-COVID-19 condition (PCC) remain uncertain despite clearer clinical factors, posing challenges for healthcare professionals. This article investigates the demographic and clinical characteristics of PCC patients and compares their healthcare resource utilization in comparison to a patient cohort representative of the population. Methods: A retrospective and cohort-comparative observational study was conducted, comparing PCC population before and after diagnosis with a control group. Demographic and clinical variables were analysed to describe the population. Economic analysis was performed to evaluate the resource costs in procedures and primary, secondary and emergency care. Results: PCC patients (N=341) were older with higher cardiovascular risk factors compared to controls (N=49,078). There were differences in the socio-economic distribution between male and female in the PCC patients. Hypertension and diabetes mellitus type 2 were the most common chronic diseases observed among the case patients. PCC patients were four times as costly as control patients, with increased utilisation of healthcare resources. However, post-diagnosis PCC patients showed a reduction in costs, primarily driven by decreased primary care visits and hospitalisations. Conclusions: Coordinated care for PCC patients leads to cost reductions and improved resource utilisation. Further research should investigate long-term health outcomes and establish causal relationships between COVID-19 sequelae and healthcare resource utilisation.Item type: Item , Fractional interacting particle system: drift parameter estimation via Malliavin calculus(Elsevier, 2026) Amorino, Chiara; Nourdin, Ivan; Shevchenko, RadomyraWe address the problem of estimating the drift parameter in a system of N interacting particles driven by additive fractional Brownian motion of Hurst index H > 1/2. Considering continuous observation of the interacting particles over a fixed interval [0, T ], we examine the asymptotic regime as N ->8. Our main tool is a random variable reminiscent of the least squares estimator but unobservable due to its reliance on the Skorohod integral. We demonstrate that this object is consistent and asymptotically normal by establishing a quantitative propagation of chaos for Malliavin derivatives, which holds for any H=(0, 1). Leveraging a connection between the divergence integral and the Young integral, we construct computable estimators of the drift parameter. These estimators are shown to be consistent and asymptotically Gaussian. Finally, a numerical study highlights the strong performance of the proposed estimators.
