An outbreak of foot and mouth disease (FMD) can distort livestock markets. In this paper we have simulated welfare effects due to the risk of a hypothetical FMD outbreak and trade distortions associated with the disease. The analysis was carried out with stochastic dynamic partial-equilibrium...

An optimising model is developed to determine the .sequence of total allowable catches of western mackerel which would result in the maximum present value of the stream of annual rents. It is found that the optimal steady state fishing mortality would be one half to one third of recent levels....

Carbon pricing was conducted through the subsidy payment for thinning activities in Japan within the optimization framework for the forest stand management. The optimal forest stand management model called DP-KYSS (dynamic programming model for Kyushu stand simulator) was utilized for the...

In many areas of developing countries, economic and institutional factors often combine to give farmers incentives to clear forests and repeatedly plant food crops without sufficiently replenishing the soils. These activities lead to large-scale land degradation and contribute to global warming...

A dynamic bio-economic model is used to show that, without technological and policy intervention, soil nutrient balances, income and nutrition could not be substantially or sustainably improved in a highland area of Ethiopia. Although cash incomes could rise from a very low base by more than 50%...

A dynamic bio-economic model is used to examine natural resource use, the resulting nutrient balances and economic outcomes in a poor country under a range of technological and policy intervention scenarios. With limited technological intervention over a twelve year planning period, incomes rise...
