In this paper we investigate the minimization process of the exact cost function for a continuous review (Q,R) inventory model with non-negative reorder point and fixed lead-time. Backorders are allowed and the unit shortage cost is used to determine the expected annual shortage cost. Provided...

The article deals with the cost function at a mathematical level that only requires knowledge of differentials, but except for that, it keeps rigor at a high level. It only states theorems that require long proofs. The article justifies the existence of the cost function, points out its...

Increasingly, state and local governments are promoting intergovernmental coordination, cooperation, and/or outright consolidation (3Cs) based on the perceived economies of scale advantages of such joint actions. However, the growing public finance and political science literature on...

Färe and Mitchell(1992) have shown that cost functions for a multi-output firmobey a particular output-scaling law if and only if the underlyingproduction technology is ray-homothetic. Multi-output firms,however, frequently change their output mix in addition to theirscale. Therefore, it is...

This paper proposes a multiple-output Symmetric Generalised McFadden (SGM) cost function, incorporating both exogenous and endogenous technological change. Whilst exogenous technological change is captured by the usual time trend, endogenous or price-induced technological change is cast within a...

Cost functions as the foundation of managerial decision making usually assume a linear cost function with fixed and variable costs. The latter are dominantly regarded as being identical for increasing and for decreasing activity levels. However, empirical research shows that the decline in costs...
