Relational Contract Theory Overview

Jul 28, 2025

Overview

This lecture introduces relational contract theory, contrasts it with classical and neoclassical theories, and explains its key features, criticisms, and place within broader legal studies.

Relational Contract Theory

  • Relational contract theory emphasizes the social and communal roots of contracts, focusing on human relationships rather than just economic efficiency.
  • Ian Macneil criticized neoclassical contract theory's focus on rational self-interest, arguing it overlooks the importance of ongoing relationships.
  • Macneil, influenced by empirical sociological studies (notably Macaulay's work), observed real-world commercial practices where written contracts often take a backseat to business customs and trust.
  • The theory contends that contract formation is gradual, involving ongoing negotiation and relationship-building, rather than a single event.
  • Contracts exist on a spectrum: "discrete" contracts (one-off, minimal relationship, e.g. buying gas) to "relational" contracts (long-term, trust-based, e.g. complex business deals).
  • Discrete contracts focus on detailed planning and legal terms due to low trust; relational contracts rely more on social norms and ongoing interaction.
  • Business practices (such as those in the Australian Navy contracts) have adopted relational approaches, focusing on managing relationships and processes rather than exhaustive contract terms.

Criticisms and Application

  • Critics argue relational contract theory lacks clear, determinate legal principles, as it originated from sociological observation rather than legal doctrine.
  • Courts have begun to use the concept of relational contracts in disputes, sometimes importing duties like good faith into long-term, complex contracts.
  • Business literature focuses on identifying and managing the relational "norms" that foster successful long-term contract performance.

Broader Legal Context

  • Contract law interacts with other bodies of law: equity (remedies beyond common law), tort (public law obligations), and unjust enrichment (basis for restitution).
  • Contract A (the current unit) covers contract formation: intention, capacity, offer, acceptance, consideration, and terms (express and implied).
  • Contract B (the sequel) examines problems after formation: vitiating factors, estoppel, illegality, discharge, breach, and available remedies.

Key Terms & Definitions

  • Relational Contract Theory — Focuses on the social and ongoing relationship aspects of contracts, not just isolated transactions.
  • Discrete Contract — A one-off transaction with minimal relationship or trust between parties.
  • Spectrum/Continuum of Contract Behavior — Range from discrete to highly relational contracts based on the degree of ongoing interaction.
  • Norms (in relational contracts) — Informal rules and expectations governing behavior in ongoing business relationships.
  • Equity — Legal principles that provide remedies where strict application of common law would be unjust.
  • Estoppel — Doctrine preventing a party from acting contrary to a promise or representation when another has relied on it.

Action Items / Next Steps

  • Read the article by Macaulay for further context on empirical contract studies (optional).
  • Complete assigned readings from Patterson on the role of equity in contract law.
  • Prepare questions or topics for discussion in the upcoming Zoom session.
