Using an expected mean-variance model the changes in farm enterprise levels and indirect utility were examined under conditions of risk aversion, budget constraints and gross margin variance. An extension of the comparative statics of the expected mean-variance model was adopted by introducing a...

Malaysia’s rice sector is highly protected, with the protection justified largely by arguments for food security. The government intervenes in the rice market by providing subsidies to farmers and consumers as well as imposing high import duties. Furthermore, the rice trade is controlled...

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...

Input controls in fisheries have been criticised for negatively affecting the efficiency of fishers through incentives to substitute inputs. A stochastic frontier analysis will be used to investigate the influence that input controls have had on the technical efficiency of fishers who operate in...

Annual time series data for the period 1950-51 through 1975-76 are used to estimate the price elasticity of aggregate Australian agricultural supply using two methods. The short-run elasticity is estimated to be highly inelastic but it has been increasing through time. The preferred estimate of...

Co-operation in research is a complex question which would seem to depend to a large extent on a number of necessary and sufficient conditions for success. In this note an attempt is made to define some of these conditions and then reflect on a few possibilities for co-operation between...

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...

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...

The integration of detailed farm supply models with the basic spatial equilibrium model, is outlined. The direct linking of farm linear programming models with the spatial equilibrium model is achieved so that both prices and quantities are endogenous. Both the farm model and the spatial...

This paper reports on an expanded and revised version of the spatial equilibrium model of the Australian dairy industry developed by MacAulay (1997). In the expanded version there is demand for five manufactured products. The transformation from bulk milk to final product is modelled by...
