Why a need should exist for hundreds of different contract laws capable of regulating a sale of goods is far from obvious. Attempts have been made to cut back and tackle the incongruities between different legal regimes. This contribution offers a conceptual framework for thinking about the variety of private laws, the need for unification, and ways to achieve it. The economics of network effects explain why standardization is often beneficial and how it can be accomplished—or missed. This chapter suggests predictions about the scope of market standardization in two particularly important areas, contract law and company law. One policy implication is that international standardization does not depend on crafting uniform law. The laws of national jurisdictions can be suitable as market standards for cross-border transactions. This adds a new perspective to the continuing debate about regulatory competition between jurisdictions: The winners of the race are decided as much by network effects as by differences in the substantive quality of their laws. Better law standardization can be a possible and desirable outcome of jurisdictional competition. It deserves careful consideration whether enacting international uniform law promises a significant improvement over jurisdictional competition that justifies the cost.
