Intermediation Entropy in Lateral Law Firm Search: A Diagnostic Model of Candidate Encumbrance, Practice Group Accounting, and P&L Leakage

This diagnostic report presents a structural framework for analyzing lateral talent acquisition in the legal market. Rather than a standard qualitative review, the paper models the formal routing mechanics and information flows that occur when candidates engage with third party search channels. The analysis examines how contractual claim windows and applicant tracking portals interact to influence candidate progression across multiple internal openings. By treating the submission path as a mathematical state space, the report quantifies internal pipeline friction, including expected fee variables and duplicate review routing. The study deploys a continuous time Markov model for pipeline delay, a jump diffusion model for administrative evaluation shocks, a mechanism design framework for volume submission strategies, and a cost functional tied to practice group economics. The objective is to provide law firm leadership and technology strategy teams with a rigorous quantitative toolkit for optimizing process design, improving candidate matching, and reducing information loss in the lateral labor market.
