Yale law professor Ian Ayres continues his American Contract Law course with a short lecture on remedies, focusing on liquidated damages clauses and the settlements parties reach to avoid litigation. Part of a numbered sequence built for Coursera's American Contract Law I and II, this installment sits under the course's remedies unit, following material on injunctions and specific performance. Ayres explains why courts will enforce a contract clause specifying damages in advance, when such a clause instead gets struck down as an unenforceable penalty, and how the same logic about predicting and pricing breach plays into how parties negotiate settlements once a dispute arises. The style is plain and doctrinal, working through the legal test with examples rather than case narration, aimed at students moving through the course's remedies sequence in order rather than viewers looking for a standalone survey of contract law.
