Selective Conscription: Sequential Allocation under Incomplete Information in Brazil’s Military Recruitment and Retention System


Daniel Gersten Reiss

Employers in Brazilian labor courts are ordered to pay something in roughly nine of every ten adjudicated claims, and a composition is available at any time at a fraction of what a judgment costs them. Yet large employers decline to compose, claim after claim, for years. We show that this is the equilibrium of a repeated game in which a long-lived defendant faces a continuing flow of short-lived claimants who differ in the personal cost of carrying a claim. The defendant is not buying a cheaper resolution of the present claim; it is buying a public record of refusing to compose, which lengthens the expected duration of any claim brought against it and thins the flow of claims it will face in future. The mechanism requires neither divergent beliefs about the merits nor private information. Three results carry the argument. A reputation for toughness deters entry if and only if the ratio of the two values at stake is smaller than the ratio of the two delays, each measured as a discounted annuity, a condition that is automatic when compositions price at the claimant’s reservation value. Because claimants differ, deterrence is always partial and the filing rate is bounded away from zero at every reputation the defendant can attain, so the stationary outcome is persistent litigation rather than its disappearance. And permanent toughness requires the defendant’s patience to exceed a threshold that falls with the responsiveness of entry and with the speed at which the market’s record forms. We take the model to approximately 130,000 decisions of Brazil’s largest regional labor court (TRT-2, São Paulo) for 2001–2017, obtained by text mining. The corpus establishes the institutional configuration the model assumes:
court-fee waivers granted essentially automatically and held by 84.7% of claimants, no exposure of the losing claimant to the employer’s attorney fees, and contingent representation, which together produce a lottery with no losing ticket and guarantee participation at any degree of risk aversion. It also establishes the constraint that forces our definition of reputation, since an employer that disputes everything still loses most of what it disputes and cannot build a record of victories. We do not report a calibration: composition rates are not observable in a corpus of decisions, and we set out what would be needed to measure the model’s remaining objects.

Keywords: Litigation; Settlement; Labor Courts; Repeated Games; Reputation; Risk Aversion; Text Mining.

Contagem regressiva: 2 dias para o International Workshop on Game Theory and Economic Applications

🔴 FALTAM 2 DIAS!

No dia 26 de julho, a FEAUSP se transforma no centro mundial da Teoria dos Jogos.

Pela primeira vez, SEIS prêmios Nobel de Economia estarão reunidos em um único evento no Brasil:

🏅 Paul Milgrom (Nobel 2020) — presencial
🏅 Roger Myerson (Nobel 2007) — presencial
🏅 Alvin Roth (Nobel 2012) — presencial
🏅 Robert Aumann (Nobel 2005) — online
🏅 Robert Wilson (Nobel 2020) — online

O 4th International Workshop on Game Theory and Economic Applications (IWGTEA) é organizado pela professora emérita Marilda Sotomayor — a única brasileira a assinar um livro ao lado de um ganhador do Nobel (Alvin Roth) — e reúne também nomes como Gabrielle Demange, Ehud Kalai, Hervé Moulin e o brasileiro Aloísio Araújo.

Diferente de um congresso tradicional, o IWGTEA nasceu como uma escola: o foco é colocar estudantes de todo o mundo frente a frente com as mentes que redesenharam mercados inteiros — de sistemas de residência médica a leilões de telecomunicações.

📅 26 de julho a 2 de agosto de 2026
