Optimal Property Rights in Financial Contracting

In this paper we propose a theory of optimal property rights in a financial contracting setting. Following recent contributions in the property law literature, we emphasize the distinction between contractual rights, that are only enforceable against the parties themselves, and property rights, that are also enforeceable against third parties outside the contract. Our analysis starts with the following question: which contractual agreements should the law allow parties to enforce as property rights? Our proposed answer to this question is shaped by the overall objective of minimizing due diligence (reading) costs and investment distortions that follow from the inability of third-party lenders to costlessly observe pre-existing rights in a borrower's property. Borrowers cannot reduce these costs without the law's help, due to an inability to commit to protecting third-parties from redistribution. We find that the law should take a more restrictive approach to enforcing rights against third-parties when these rights are i) more costly for third-parties to discover, ii) more likely to redistribute value from third-parties, and iii) less likely to increase efficiency. We find that these qualitative principles are often reflected in observed legal rules, including the enforceability of negative covenants; fraudulent conveyance; corporate veil-piercing; and limits on assignability.
