Time-Limited Property Rights and Investment Incentives

Although it is axiomatic that property rights of infinite duration are necessary for owners to make efficient long term investments in their property, time limits on property rights are pervasive in the law. This paper provides an economic justification for such limits by arguing that they actually enhance property values in the presence of various sorts of market failure. The analysis offers a coherent approach for understanding what otherwise appear to be unrelated doctrines in the law.

Salvaging Historic Shipwrecks

The salvage of historic shipwrecks involves a debate between profit-oriented salvagers, who wish to maximize profit, and archeologists, who wish to maximize historical value. We use a principal-agent model to derive the optimal reward scheme for salvagers, including a minimum duty of care in conducting the salvage operation. A review of U.S. and international law suggests that, while there is an emerging recognition of the need to devote greater care to salvaging those wrecks that are located, current doctrines provide inadequate incentives to locate historic wrecks in the first place.
