EVALUATING ALTERNATIVE FARMING SYSTEMS: A FUZZY MADM APPROACH AgEcon
Marks, Leonie A.; Dunn, Elizabeth G..
This paper develops a decision support method that integrates measures of achievement in the economic, environmental, and social aspects of farming. The decision support method combines multiple attribute decision making (MADM) with fuzzy logic. The fuzzy MADM model fully ranks decision alternatives relative to the preferences of decision makers and overcomes several problems inherent in other MADM approaches. It is concluded that fuzzy MADM can improve decision making on the farm.

TECHNICAL EFFICIENCY, MANAGERIAL ABILITY AND FARMER EDUCATION IN GUATEMALAN CORN PRODUCTION: A LATENT VARIABLE ANALYSIS AgEcon
Kalaitzandonakes, Nicholas G.; Dunn, Elizabeth G..
In this study it is argued that conflicting empirical results on the relationship between technical efficiency and education may be in part attributed to difficulties in the measurement of key variables. Calculation of technical efficiency with three alternative frontier methods for a sample of Guatemalan corn farms resulted in significant differences both in the average technical efficiency of the sample and the efficiency rankings of individual farms. Furthermore, following two-step procedures where technical efficiency is regressed against a set of explanatory variables, it is shown that the choice of efficiency measurement technique can alter the importance of education as a contributing factor to increased technical efficiency. An alternative...
