I. INTRODUCTION
Inspired by the close interaction of law and economics, common law scholars have applied an economic perspective to bear legal problems in the last decades. This scholastic effort has produced interesting results in the United States where the sophistication of the courts and its judges allow a pragmatic application of economic theories to actual controversies.
Economists analyze legal rules in terms of efficiency. Reallocating resources in a society is considered efficient only if that reallocation makes someone better without making some others worse off. Economic theory has been broadly applied in the United States, particularly in the area of contract law. At the heart of its application lies the efficient breach hypothesis, a milestone of contract law and the law and economics movement. Simply put, the hypothesis suggests that promisors should be permitted, if not encouraged, to breach a contract whenever the net gains resulting from said breach exceed the net gains of performance. Parties are therefore encouraged to complete the projects they consider efficient while abandoning any other contractual project that results inefficient or wasteful. [More]
