The concept of diminishing marginal utility is a cornerstone of economic theory. The consumption of a good typically creates satiation that diminishes the marginal utility of consuming more. Temporal satiation induces consumers to increase their stimulation level by seeking variety and therefore...

The paper presents a revision of the contemporary reductionistic demand theory, replacing the studying object, i.e. an individual, with a fuzzy collection of market buyers, regarded as a “statistical ensemble of consumers”. The new holistic market demand theory formally retains the...

The models we present in this chapter are related to two classical inventory models: The EOQ model of Harris (1913) and the dynamic lot size model of Wagner and Whitin (1958). In relation to the EOQ model, our models depart in three different ways: (1) the EOQ model assumes that the problem...

We study a two-stage purchase contract with a demand forecast update. The purchase contract provides the buyer an opportunity to adjust an initial commitment based on an updated demand forecast obtained at a later stage. An adjustment, if any, incurs a fixed as well as a variable cost. Using a...

This article analyzes a discrete time lost sales inventory system with partially observed demand and unobserved shrinkages which happen both before and after the demand realization. When the demand exceeds the remaining inventory, the unmet demand is lost and unobserved. This problem in general...

This article analyses the impact of the interplay between the demand response, wind penetration and hydropower in the Nordic power market. We develop a long-term equilibrium model in which the thermal power capacity adjusts to the zero-profit level over varying real-time pricing adoption rates...

We deal with the problem of a profit-maximizing vendor selling a perishable product. At the beginningof a planning cycle, the vendor determines a minimum committed order per period. During the cycle, he may also place a supplemental order in each period based on the observed demand signal in...

In this paper we analyze a stochastic dynamic advertising and pricing model with isoelastic demand. The state space is discrete, time is continuous and the planning horizon is allowed to be finite or infinite. A dynamic version of the Dorfman-Steiner identity will be derived. Explicit...

We present a dynamic, multi-item model to analyze the optimal joint inventory, pricing, and bundling decisions for a firm over a finite horizon. We develop a novel demand model that transfers the discrete bundling decision and the corresponding pricing decision into a market share decision. We...
