A Statistical Market-Design Framework for Academic Job Markets

The academic job market for new statisticians is highly congested at the interview stage, where departments must rank and select candidates from large applicant pools without credible signals of candidate interest. As a result, interviews and offers are often misallocated, leading to unfilled positions and poor mutual fit. We frame interview allocation as a statistical ranking problem under uncertainty and propose a market-design framework that incorporates structured preference signaling into interview selection. Candidates submit a single standardized questionnaire describing preferences over interpretable job characteristics, which departments combine with traditional application materials and historical hiring data to estimate candidate-specific acceptance probabilities and expected utilities. To account for estimation uncertainty, we employ a confidence-calibrated ranking procedure based on pairwise utility comparisons that provides statistical guarantees for candidate ranking. We establish that truthful participation is optimal for candidates and that preference information improves departmental outcomes and matching stability. We use a dataset of U.S. statistics departments to show that the proposed framework substantially increases matching rates, improves match quality, and reduces hiring failures relative to the current practice.

A Data Envelopment Analysis Approach for Assessing Fairness in Resource Allocation: Application to Kidney Exchange Programs

Kidney exchange programs have substantially increased transplantation rates but also raise critical concerns about fairness in organ allocation. We propose a novel framework leveraging Data Envelopment Analysis (DEA) to evaluate multiple dimensions of fairness-Priority, Access, and Outcome-within a unified model. This approach captures complexities often missed in single-metric analyses. Using data from the United Network for Organ Sharing, we separately quantify fairness across these dimensions: Priority fairness through waitlist durations, Access fairness via the Living Kidney Donor Profile Index (LKDPI) scores, and Outcome fairness based on graft lifespan. We then apply our conditional DEA model with covariate adjustment to demonstrate significant disparities in kidney allocation efficiency across ethnic groups. To quantify uncertainty, we employ conformal prediction within a novel Reference Frontier Mapping (RFM) framework, yielding group-conditional prediction intervals with finite-sample coverage guarantees. Our findings show notable differences in efficiency distributions between ethnic groups. Our study provides a rigorous framework for evaluating fairness in complex resource allocation systems with resource scarcity and mutual compatibility constraints.
