We consider optimal cooperation in transboundary air pollution abatement among several countries under incomplete information. The countries negotiate on establishing a gradual cooperative emission reduction program to reduce the damages caused by sulphur depositions. Local information available...

Heavy positively autocorrelated natural fluctuations in a fisheries stock level are problematic for fisheries management, and collapses in the stock dynamics are difficult to avoid. In this paper, we compare three different harvesting strategies (proportional harvesting, threshold harvesting,...

A general dynamic model of fishing under harvest share contracts is developed. Vessel owners hire fishermen to work on the vessels and pay them a share of the catch and an additional wage. The harvest rate depends on labor input, capital input, and stock level. Neither of the agents is...

Transboundary air pollution is analysed as a dynamic game between Finland and the nearby areas of the Soviet Union. Sulphur emissions are used as the environmental control variables and the acidities of the soils as the state variables. Acidification is consequently considered to be a stock...
