The issue of economy of scale exists both in terms of the quantity of agricultural production and also in its quality aspect. From the perspective of production cost, we build an agrifood quality-cost function and its elasticity estimation model and then empirically estimate this model in...

In this article we study three types of uncitedness in Library and Information Science journals: uncitedness for articles, authors and topics. One important aspect in this study is giving accurate definitions of the indicators for measuring uncited papers, uncited authors and uncited topics. It...

Banerjee and Pattanaik (1996) proved a theorem that the maximal set with respect to a quasi-ordering can be fully recovered by defining the greatest sets with respect to each and every ordering extension thereof and taking their union. Donaldson and Weymark (1998) proved a theorem that a...

In this paper we characterize choice behaviour that picks the median element from a set of feasible alternatives. It is easily seen that this choice behaviour violates most of the standard consistency conditions for set contraction and set expansion. The paper offers a complete characterization...

We provide characterizations of four new rules for individual decision-making under complete uncertainty. They are what we call the min-max rule, the max-min rule, the lexicographic min-max rule and the lexicographic max-min rule. These rules provide orderings of the sets of possible outcomes...

In this paper, we attempt to combine the concept of a choice function with a procedural aspect. We examine an individual’s choices over alternatives when the available options are linked either to the procedure by which these alternatives came into existence or to the degree of availability of...
