Game Theory and Settlement Negotiations in Commercial Disputes
Most commercial disputes settle before adjudication. The settlement process involves strategic interaction that game theory helps explain and predict. Practitioners who understand these dynamics negotiate more effectively.
The Basic Model
Divergent Expectations
Litigation occurs when parties have divergent expectations about trial outcomes. If both parties accurately predicted the result, they would settle to avoid litigation costs. Optimism bias and private information explain why cases go to trial.
The Settlement Range
Settlement is possible when the plaintiff's minimum acceptable offer is less than the defendant's maximum acceptable offer. This range exists when both parties prefer settlement to the expected value of litigation minus costs.
Strategic Behavior
Signaling
Litigation conduct signals private information. Aggressive discovery may signal confidence; settlement overtures may signal weakness. Sophisticated parties account for these signals when interpreting opponent behavior.
Commitment
Credible commitment to positions enhances bargaining power. Lawyers who develop reputations for refusing to settle below certain thresholds extract better settlements—but only if the commitment is credible.
Screening
Defendants may use litigation conduct to screen plaintiff types. Aggressive defense strategies impose costs that weak plaintiffs cannot bear, causing them to accept lower settlements or abandon claims.
Multi-Party Complications
Coalition Formation
Disputes involving multiple parties create coalition dynamics. Defendants may attempt to settle with some plaintiffs to weaken others; plaintiffs may coordinate to prevent divide-and-conquer strategies.
Joint and Several Liability
Joint and several liability creates strategic complexity. Settling defendants may face contribution claims; non-settling defendants may face increased exposure. These dynamics affect settlement incentives in predictable ways.
Timing Considerations
Information Revelation
Litigation reveals information that affects settlement value. Parties must decide whether to settle early with less information or later with more—trading certainty against information value.
Deadline Effects
Settlement rates increase dramatically as trial approaches. This pattern reflects the resolution of uncertainty and the increasing salience of litigation costs.
Conclusion
Effective settlement negotiation requires understanding the strategic dynamics at play. Game theory provides a framework for analyzing these dynamics and developing negotiation strategies that account for opponent incentives and likely responses.
