The dynamic efficiency of closures in bioeconomic systems depends upon stock levels and in situ values that evolve over time, and on relative costs of implementation. A model of a harvested metapopulation is presented in which second-best reduction of harvest from open-access levels using input...

This article presents a US perspective on the influence of government policies on the nature and development of advanced marine electronic instrumentation (MEI) technologies in Europe. US firms traditionally have enjoyed a strong international competitive advantage in the MEI field, but European...

This article reports some results of a study to enhance the effectiveness of a prospective protocol on land-based marine pollution (LBMP) in the Wider Caribbean Region (WCR), which is under negotiation. We argue that the environmental, economic, and institutional diversity of the region as a...

The dynamic efficiency of closures in bioeconomic systems depends upon stock levels and "in situ" values that evolve over time, and on relative costs of implementation. A model of a harvested metapopulation is presented in which second-best reduction of harvest from open-access levels using...

The economics literature on fisheries has focused primarily on stock externalities and, to a lesser degree, on crowding externalities. Yet for many fisheries, harvesting activities may affect the underlying biological productivity of the fish stock by impacting the forage or habitat quantity or...

The potential emergence of an ocean mining industry to exploit seafloor massive sulfides could present opportunities for oceanographic science to facilitate seafloor mineral development in ways that lessen environmental harms.

Failure to manage the harvest of a metapopulation at its underlying ecological scale can lead to extirpation of discrete subpopulations and reduce productivity. However, it may be difficult and costly to assess and manage stocks at a finer spatial scale, and there is generally greater...
