Quality of decisions in inventory management models depends on the accuracy of parameter estimates used for decision making. In many situations, error in decision making is unavoidable. In such cases, sensitivity analysis is necessary for better implementation of the model. Though the newsvendor...

We propose tests for equality of treatment effects in the context of a double-blind 2 x 2 cross-over trial which do not require treatment codes to be unblinded and thus can be used as a part of the interim analyses. We first discuss the set-up of a 2 x 2 cross-over trial and state the important...

Due to the preference of satiation (of the profit target) over maximization (of expected profit) in uncertain situations, the newsboy problem with the satiation objective is an important practical problem. In the multi-product setting, practically usable solution methods are available only for...

Meeting the profit target is often preferred over maximizing expected profit in uncertain business environments. Research into the newsboy problem with satiation objective started quite early. However, the progress has been slow, particularly in the multi-product setting. We study the genral...

Preference of satiation of a target performance over maximization of expected performance in uncertain situations is well-documented in the economics literature. However, the newsboy problem with satiation (of a prot target) objective has not received its due attention. In the multi-product...

Meeting the prot target is often preferred over maximizing expected prot in uncertain business environments. Research into the newsboy problem with satiation objective started quite early. However, the progress has been slow, particularly in the multi-product setting. We study the general...

Sensitivity analysis is an integral part of inventory optimization models due to uncertainty associated with estimates of model parameters. Though the newsboy problem is one of the most researched inventory problems, very little is known about its robustness. We study sensitivity of expected...

A firm’s ‘competitive advantage’ is considered to arise from certain ‘factors internal to the firm as postulated by the resource based view’ or from ‘external sources and industry structure.’ However, it remains unclear as to “how” these factors result in competitive advantage,...

The objective of this paper is to review and synthesize the literature of psychological contract in order to provide a comprehensive framework of psychological contract through individual and multi-level analysis. The article provides an inclusive review of antecedents (individual and...

The influence of factors outside the boundaries of organization is largely ignored in the examination of psychological contract. The objective of the current research is to empirically examine the association between industry/sector and psychological contract. The article examines the variation...
