    Abstract: A biomass model of a wild salmon (Salmo salar) river recreational fishery is formulated, and the ways in which economic and biological conditions influence harvesting, stock size, profitability, and the benefit of the anglers are studied. The demand for recreational angling is met by fishing permits supplied by profit maximizing landowners. In line with today’s stylized management practice in Norway, it is assumed that the suppliers do not take into account the fact that this year’s fishing effort influences next year’s stock size. Both price-taking and monopolistic supply is studied. These myopic schemes are contrasted with the social planner solution. Gear regulations in the recreational fishery, but also the commercial fishery, are analysed under the various management scenarios and the paper concludes with some policy implications. One novel result is that imposing gear restrictions in the marine fishery may have the opposite stock effect of imposing restrictions in the recreational fishery.

    Abstract: Despite wetlands being amongst the Earth's most productive ecosystems, they have been degraded and lost at an unprecedented rate globally, especially throughout the last century. In recognition of the importance of the crucial ecological functions and economic benefits they provide, international efforts, such as the Ramsar Convention, and European Union level efforts, such as the Water Framework Directive (2000/60/EC), are now in place to ensure conservation, sustainable management and improvement of the remaining wetlands. This paper aims to assist policy makers in formulating efficient, effective and sustainable wetland conservation and management policies by providing them with the results of a valuation study using the Cheimaditida wetland in Greece as a case study. A choice experiment is employed to estimate the benefits of the non-use values of the Cheimaditida wetland that accrue to the Greek public. Results from this choice experiment reveal that there are positive and significant non-use values of this wetland for whose conservation the public is willing to pay. These results can be combined with private use values of wetlands, and weighed against the costs of alternative wetland management scenarios in order to carry out a comprehensive cost benefit analysis. Thus they can aid in the design of socially optimal policies for conservation and sustainable management of the Cheimaditida wetland, with implications for other wetlands in Greece and the rest of Europe.

    Abstract: The desirability of airport congestion pricing largely depends on whether dominant airlines otherwise fail to internalize their self-imposed congestion delays. Brueckner (2002) and Mayer and Sinai (2003) find (weak) statistically significant evidence of internalization. We replicate and extend these models by refining their measures of delay and controlling for fixed and random airport effects. For twenty-seven large US airports, we estimate every flight’s congestion delay attributable to its operating time. These time-dependent queuing delays result from traffic rates temporarily exceeding airport capacity, and are precisely the delays susceptible to peak-load congestion pricing. As modified, the models reject the internalization hypothesis.
