This article integrates fuzzy set theory in Data Envelopment Analysis (DEA) framework to compute technical efficiency scores when input and output data are imprecise. The underlying assumption in convectional DEA is that inputs and outputs data are measured with precision. However, production...

Most, if not all, production technologies are stochastic. This article demonstrates how data envelopment analysis (DEA) methods can be adapted to accommodate stochastic elements in a state-contingent setting. Specifically, we show how observations on a random input, not under the control of the...

This study proposes non-parametric techniques for environmentally sensitive analysis of economic performance. The techniques are implemented using Canadian pulp and paper industry data covering the period from 1959 to 1994. The results indicate that productivity improvement has been more...

Increasing use of Benefit-Cost Analysis (BCA) in ex ante research evaluation has not been accompanied by consensus on the increased returns flowing from the evaluation effort. There are likely to be a wide range of views held by researchers, agricultural economists and research managers on how...

Many explanations of agricultural technology adoption have either been based loosely on diffusion concepts and have ignored economic factors or have been static economic models that ignore dynamic and spatial aspects of adoption. In this paper we propose a model of adoption which incorporates...

An optimal stochastic control model of grazing that incorporates both pasture and livestock dynamics is presented. The model is solved numerically using Markov chain approximation methods. Markov chain approximation methods have a number of advantages as a means of solving stochastic optimal...

Harold Hotelling proposed the first method for non-market valuation. Most of us believe this is the Travel Cost Method. In this paper I argue that the first method is from Hotelling's seminal study on the extraction of exhaustible resources. The first method is dynamic optimisation as applied to...

Domestic Resource Costs (DRC) are widely used to measure comparative advantages in production of any commodity in a country. Basically, the DRC measures the opportunity costs of producing specified goods with reference to border prices for both inputs, especially imported and/or tradable, and...
