This paper explores how regulation of an open access fishery influences the value of a coastal habitat that serves as breeding and nursery grounds. A model of the fishery supported by a coastal wetland is developed, which includes a quota rule that restricts harvest to a fixed proportion of the current stock. The model is applied to mangrove-dependent shellfish and demersal fisheries in Thailand. The value of the welfare effects associated with a change in a supporting coastal habitat is influenced significantly by whether or not the regulatory quota can adjust in response to these changes. Welfare losses are considerably higher when the quota is fixed as opposed to when it can be adjusted. With the restriction in place, effort cannot change to offset the decline in biomass, and as a result, there is a much larger fall in harvest. In addition, the welfare losses are much larger for the shellfish compared to the demersal fisheries. The analysis illustrates that imposing a regulatory rule on an open access fishery has important implications for valuing any linkage between coastal breeding and nursery habitat and a near-shore fishery.

AbstractThis paper sets up a dynamic model to study the distributive effects of privatizing an open access resource. We show that with or without discounting, privatization is not always Pareto improving. We further derive conditions under which the poor are made worse off when private use rights are equally distributed compared to a situation with open access resource. These conditions imply that privatization is Pareto improving if the natural resource is sufficiently productive, inequality in alternative private project opportunities is low, and if there is no discounting. In addition, we show that once reduction in income from resource harvesting during the transition to a new steady state is accounted for, privatization is desirable for the poor only for very productive natural resources and low discount rates.

Zusammenfassung. Psychische Störungen können über die ganze Lebensspanne auftreten. Strukturierte klinische Interviews sind zentrale Hilfsmittel für ihre rasche, zuverlässige und umfassende Diagnostik. Im deutschsprachigen Raum stehen mit den Verfahren der DIPS-Familie Interviews zur Diagnostik psychischer Störungen über die gesamte Lebensspanne zur Verfügung, die seit den 90er Jahren regelmäßig aktualisiert wurden. Ihre Reliabilität, Validität und Akzeptanz wurde wiederholt in großen Stichproben aus ambulanten, stationären und Forschungssettings überprüft. Die Einführung des DSM-5 erforderte eine umfassende Überarbeitung der DIPS-Interviews, deren wesentliche Merkmale dargestellt werden. Um die breitere Verwendung von strukturierten klinischen Interviews zu fördern, werden die Verfahren der DIPS-Familie neu als „Open Access-Dokumente“ zur Verfügung gestellt. Abschließend werden weitere Entwicklungen zu Training, Dissemination und Computerisierung im Ausblick angesprochen.
