the aim of this study was to represent effective componentsin demand chain which help organizations attain high performance levelsthrough identification of these components and determining theirdegree of importance. the following questions were major ideas of thisstudy: what are the most effective components in demand chain? andhow are they effective on organizational performance? to this end,m...

We model unobserved preference heterogeneity in demand systems as random Barten scales in utility functions. These Barten scales appear as random coefficients multiplying prices in demand functions. Consumer demands are nonlinear in prices and may have unknown functional structure. We therefore prove identification of additive Generalized Random Coefficients models, defined as additive nonparam...

demand for farm output is theoretically consistent with consumer demand and marketing performance. many studies have focused on demand interrelationships at the retail level, but not on the demand for farm output. in this study, derived demand elasticities of sheep, beef and chicken were estimated in a complete system of demand functions by seemingly unrelated regression estimator (sure) for th...

Sanitation improvement is crucial in saving lives that are lost due to water contamination. Progress towards achieving full sanitation coverage is still slow in low-income informal settlements in most developing countries. Furthermore, resources are being wasted on installing facilities that are later misused or never used because they do not meet the local demand. Understanding demand for impr...

The newsvendor problem with pricing decision provides an important vehicle for examining how operational problems interacts with marketing issues to influence decision-making at the firm level. This paper considers the newsvendor problem with pricing and its extensions. We try to answer two questions: (1) how to model the price-dependent stochastic demand and (2) how to derive the combined pric...

We prove that combinatorial demand functions are characterized by two properties: continuity and the law of demand.

This note is a drastic revision and extension of the author’s paper (1972). We recall the following theorem of Debreu (1970) for a pure exchange economy : One is given C1 demand functions, fi, . . ,, f,, of m consumers, satisfying a certain boundary condition. Then for almost all initial allocations of commodities to the m consumers, there are only a finite number of price equilibria. Our goal ...
