Public markets, private orderings and corporate governance

In the New Property Rights approach the degree of incompleteness of markets is taken independently of the cost of the public ordering and of their eff iciency relatively to private orderings. In this approach "public markets," similarly to a Swiss cheese, are either assumed to be nonexistent empty ho les (because of infinite third party verification costs) or assumed to be s mooth and efficient (because of zero third party verification costs). When we allow for positive but not infinite third party verification costs we ar e necessarily pushed back to the insights of Commons, Cease, Fuller and Wil liamson. The degree of (in)completeness of public markets becomes an endoge nous economic problem and managers can be seen as agents that make "second order" specific investments to run specific relations that cannot be effici ently handled by public markets. Managers and the public authorities build respectively private and public "legal equilibria" that set the working rul es within which transactions can take place. Private and public legal equil ibria are not only substitutes but also complements. This complementarity i s an important source of the path dependency that characterizes the develop ment of different legal systems. The framework is applied to GM's acquisiti on of Fisher Body. We suggest that, contrary to the claims of the New prope rty Rights approach, the advantages of the acquisition were not due to the superior incentives of the new private owners but should be rather related to the replacement of public markets by the new private ordering set up by Alfred Sloan.
