The use of protected areas as a fishery management tool has been suggested as a hedge against management failures and variation in harvests. A stochastic bioeconomic model of a two-species fishery will be used to test the performance of protected areas as a management tool in a fishery with...

Standard spatial equilibrium activity analysis models, as developed by Takayama and Judge (1971), are based on linear supply and demand functions and fixed input-output coefficients. Such models are suitable for multiple market level trading systems where the fixed input-output coefficients are...

Evidence is provided on the extent to which wheat price policies operating over the period 1953-54 to 1983-84 achieved objectives related to the levels and stability of key industry variables. The general findings are that the levels of achievement have been modest and that trade-offs have been...

Over the last decade the Vietnamese government has instigated land reforms that recognise the household as the basic unit of production and allocate land use rights to households. Under the 1993 Land Law these rights can be transferred, exchanged, leased, inherited, and mortgaged. This Land Law...

In this paper a model is proposed for analysing alternative policies that might be used in allocating water in Thailand. The model used is an integration of farm linear programming models with a spatial equilibrium model, using the so-called price-linked farm and spatial model (Batterham and...

Shrimp culture areas and production of the Mekong Delta cover about 60 percent of the total shrimp areas and production of Vietnam. Especially, the Delta contributes about 80 percent of the total shrimp production for export. Rapid development of the shrimp industry is raising a number of...

Land fragmentation, in which a single farm household operates more than one separate piece of land, is significant issue in Vietnamese agriculture, especially in the North. For the whole country, there are about 75 million plots of land, an average of 7-8 plots per farm household. Such...

The use of mathematical models to describe the interactions of variables is useful in modern management. In this paper, a 'mixed' model combining the knapsack problem, a household model and a form of spatial equilibrium model into a modelling framework is developed. The impacts of changes in...

Game theory offers an alternative approach to standard means of resource assessment which can be of value in the definition and assessment of policy options for competing parties. Using a Nash co-operative game it has been possible in this paper to show the significance of fishing strategies for...
