This paper focuses on the optimal quality regulation of vertically differentiated duopolies in the presence of asymmetric information. In the model presented there are cross-effects on the information rent. Contrary to standard single-agent models, the production levels are distorted in favour of the most efficient firm, whose production level is increased under asymmetric information relative ...

This paper explores the issue of using marine reserves in combination with quotas as fisheries management tools using a patchy environment model as the biological foundation. The rent generated by fishing on the total population, using optimal quotas as a management tool, is compared to the rent from the fishery when managed with quotas and a marine reserve. This is done under different assumptions ...

A transferable quota system is analysed in a two-period model with market power. So far, the management mechanisms presented in the literature to remedy market power have either not succeeded in securing efficiency in the distribution of quota within and across time periods, or have resulted in only one of the two inefficiencies being eliminated. In this paper a new mechanism is introduced where ...
