The Law and Economics of Contracts2006
The essence of a free-market economy is the ability of private parties to enter into voluntary agreements that govern the economic exchange between them. Consequently, the law that governs such agreements is critical to the functioning of such economies. While the law of property determines the configuration of entitlements that form the basis of production and exchange, and the law of torts protects those entitlements from involuntary encroachment and expropriation, it is contract law that sets the rules for exchanging individual claims to entitlements and, thus, determines the extent to which society is able to enjoy the gains from trade. Accordingly, economists interested in the welfare properties of specific institutions in particular, or the micro-foundations of exchange generally, have good reason to take account of the law of contracts. This chapter, accordingly, surveys the main issues arising in the economic analysis of contract law. We discuss both the main features of contract law as they relate to the problem of economic exchange, and how relevant legal rules and institutions can be analyzed from an economic perspective. In this introductory section, we set out the basic scope, methodology, and organization of the discussion to follow. Subsection 1.1 discusses why formal and informal contracts exist, and what economic functions they serve. Subsection 1.2 distinguishes between positive and normative issues in the economic analysis of contract law, and discusses some methodological problems associated with applying standard economic analysis to legal institutions and when engaging with legal scholarship. Subsection 1.3 identifies limits on the chapter's scope and provides bibliographic recommendations for material we don't cover; and subsection 1.4 sets out the organization of the remainder of the chapter. A caveat is in order at the outset: although it is conventional to present contract law as a discrete field, one should understand that, to a significant extent, the operation of the rules and institutions discussed below will depend on other aspects of the law, including the fields of tort, bankruptcy, procedure, and evidence. Lawyers have a cliché that describes this interdependence; they say that "the law is a seamless web." It is useful to keep in mind that many issues that economists would regard as contractual, including some important limits on contractual freedom, are governed not by contract but by tort law. Additionally, the rules relating to certain categories of exchange, such as consumer, employment, insurance, and information-licensing contracts, have developed specialized content to the point that they are often treated as distinct legal fields. Finally, the practical ability of contracting parties to assert their legal entitlements depends importantly on the procedural rules that govern courts and other enforcement institutions. Many of the specific features of contract law that we discuss below cannot be understood except as a response to the costs and other limitations of such institutions. 1.1.3 Implementing production over time Finally, contracts are valuable in promoting production in advance of exchange. Advance production typically increases the surplus available from exchange, but requires sinking resources in ways that may be unrecoverable if the contemplated exchange is not completed. For example, a clothing manufacturer can increase Enforcement costs. It is never costless to hold a party to his commitment if he is inclined to try to escape it. If the contract is being enforced through the courts, for instance, lawyers must be hired and evidence assembled, and performance or damages are likely to be awarded only after some delay. Such costs make enforcement incredible when the damages from breach are relatively 1.2.2 Positive issues While most work on the economics of contract law has sought, at least in part, normative conclusions, there is a segment of the literature devoted to predicting and explaining how different contractual rules affect private transactions, and why contracting parties might choose one contractual device rather than others. For example, a variety of authors (e.g., Joskow, 1987; Crocker and Masten, 1988; Pirrong, 1993) have investigated the connection between the use and duration of contractual agreements and the extent of relationship-specific investments.

Katz, supra note 1, at 171-72; Scott & Triantis, supra note 1, at 189. Protection of the investment might call for enforcement even when circumstances have changed so that enforcement would no longer be efficient.

For example, one can reduce the ex ante drafting costs by leaving certain matters for courts to decide later on, adding to back-end enforcement costs. Id. at 196-97.
