The primary objective in this paper is to 'promote' the use of equilibrium displacement modeling, or comparative static analysis of general function models, as a research tool in agricultural price and policy analyses. This is by no means a new tool, but it does seem to be used much less in...

An implicit rental price approach is used to analyse the determinants of farm tractor investment at the aggregate level. Three models, based on different assumed factor substitutabilities, are compared. Variations in the rental price of tractors appear to have less effect on demand than...

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...

All farmers in one stratum of a wheat storage survey who failed to answer a mail questionnaire were personally interviewed. Answers obtained from the mail respondents and from non-respondents are compared to assess the extent of non-response bias. Five suggestions for planning "high return" mail...

As a guide to the reorganisation of resources, the MVP /MFC comparison can result in the adjustment of resources to new levels which are actually further away from their optimal levels than their original values. Duloy illustrated this paradox mathematically in the context of fitted agricultural...

Technical change and the extent to which commodity supplies and input demands are interrelated in Sri Lankan peasant agriculture are explored in this paper. Using a multiple-product dual model, a seemingly unrelated system of product supply and input demand equations is estimated for four crops...

Bardsley and Harris (1987) test empirically the effects of changes In deterministic wealth and random income on the measure partial risk aversion. The paper, which is otherwise well written, failed to impose the relationship between the two effects and estimated them independently. Consequently,...

A method proposed by Clements and Sjaastad for measuring the effect of manufacturing protection on farmers' incomes is shown to be theoretically unsound, to use some inappropriate assumptions and to lead to overestimation. Even if corrected, the method seems inferior to estimating directly via...
