Alexander BillyPhD

Alexander Billy is an economist and Managing Director at Vertex, based in New York. He provides economic and statistical analysis in complex commercial disputes involving healthcare reimbursement, antitrust, commercial waste services, and breach of contract. His work spans class actions, multidistrict litigation, and arbitration, with particular expertise in class certification.

In healthcare, Alex has worked on out-of-network reimbursement disputes involving behavioral health and anesthesiology providers, arbitrations over contracted hospital reimbursement, and matters involving alleged upcoding and downcoding. He has analyzed claims data covering billions of transactions to develop reimbursement benchmarks, test whether billed and paid service levels are consistent with clinical and coding patterns, estimate damages, and evaluate exposure under alternative models. He works closely with testifying experts on affirmative reports and rebuttal analyses.

Outside healthcare, Alex has worked extensively in the waste services industry. He has supported more than ten disputes between haulers and their residential, commercial, and industrial customers concerning price increases and surcharges, including whether those charges were permitted under customer contracts and whether the issues could be resolved on a classwide basis. He also analyzed market definition for a proposed merger between two commercial waste haulers.

Alex’s research has appeared in the Vanderbilt Law Review, Northwestern University Law Review, Journal of Empirical Legal Studies, and International Review of Law and Economics. He is a co-founder and Board Chair of Free Our Vote, a nonprofit that uses data, technology, and empirical research to restore voting rights and expand economic opportunity for people with past criminal records.

Alex holds a PhD and an MA in economics from Georgetown University and a BS from Saint Vincent College.
