In this note we show that the diet problem and the benefit-of-the-doubt (BoD) aggregation are linear programming duals. That is, the primal (dual) formulation of the diet problem is equivalent to the dual (primal) formulation of the BoD model as long as food prices are set equal to one. In...

In this note we derive alternative weighting schemes that complement those of Färe and Zelenyuk (2003) for consistent aggregation of Farrell efficiencies when the technology exhibits (global) constant returns to scale.

This paper characterizes the elasticity of factor substitution in one-sector convex growth models with a general production function. It shows that an elasticity of substitution that is asymptotically greater than one is a sufficient (but not a necessary) condition for the existence of a lower...

A decomposition analysis for consumer demand functions is developed. Changes in Marshallian demand or expenditure shares functions over time are decomposed into a total substitution effect, an income effect, and a habit effect. This framework is applied to post-war Greek consumption patterns...

An alternative version of decomposition analysis, based on factor cost shares rather than input demand functions, is presented and applied to Greek agriculture. Decomposition analysis shows that most of the changes in factor cost shares during the period from 1973 to 1989 are attributed to...

The present paper extents the existing literature providing a theoretically consistent framework for measuring input-specific technical efficiency in damage control inputs within a stochastic production frontier model. The theoretical framework for modeling damage control agents is based on Fox...

This paper develops a framework for analysing the sources of total factor productivity (TFP) changes by explicitly taking into account the damage-control nature of pesticides. In the proposed framework, TFP changes are attributed to the conventional sources of growth (i.e. technical change,...

Under production uncertainty, it is shown that the LeChatelier principle holds for the derived demand of the "i"th factor if it is technically complementary (competing) with the risk-increasing (risk-reducing) quasi-fixed input and absolute risk aversion is decreasing. In addition, the...

The temporal pattern of technical efficiency in the technical inefficiency effects model, as initially modeled by Battese and Coelli (1995), is rather restrictive. Specifically, it a priori imposes a common pattern upon all firms in the sample, which in addition is monotonic over time. Obviously...
