Prior literature has demonstrated the power of zero pricing to boost consumer demand, but the current research shows a novel 'boomerang effect': a zero (vs. low, nonzero) price can lower demand when the offer comes with high incidental costs (e.g., the time cost in commuting to an offline class; the physical risk of getting a new vaccine). Five studies show that zero pricing, relative to low pricing, has a boosting (boomerang) effect on demand when incidental costs are low (high). The diverging effects of zero pricing on demand are explained by a dual-process model with a positive affective pathway and negative scrutiny pathway. Zero pricing triggers both positive affect and cognitive scrutiny of incidental costs; when incidental costs are high, the scrutiny pathway overrides the affective pathway and decreases demand. The finding has managerial implications as incidental costs often vary widely between marketing channels and over a product's life cycle., Author(s): Xiaomeng Fan [sup.1] , Fengyan Cindy Cai [sup.2] , Galen V.

We study the planar maximum coverage location problem (MCLP) with rectilinear distance and rectangular demand zones in the case where 'partial coverage' is allowed in its true sense, i.e., when [...]

This paper studies the incentive for vertical information sharing in competing supply chains with production technologies that exhibit diseconomies of scale. We consider a model of two supply chains each consisting of one manufacturer selling to one retailer, with the retailers engaging in Cournot or Bertrand competition. For Cournot retail competition, we show that information sharing benefits a supply chain when (1) the production diseconomy is large and (2) either competition is less intense or at least one retailer's information is less accurate. A supply chain may become worse off when making its information more accurate or production diseconomy smaller, if such an improvement induces the firms in the rival supply chain to cease sharing information. For Bertrand retail competition, we show that information sharing benefits a supply chain when (1) the production diseconomy is largo and (2) either competition is less intense or information is more accurate. Under Bertrand competition a manufacturer may be worse off by receiving information, which is never the case under Cournot competition. Information sharing in one supply chain triggers a competitive reaction from the other supply chain and this reaction is damaging to the first supply chain under Cournot competition but may be beneficial under Bertrand competition.

This paper presents a new model of probabilistic binary choice under risk. In this model, a decision maker always satisfies first-order stochastic dominance. If neither lottery stochastically dominates the other alternative, a decision maker chooses in a probabilistic manner. The proposed model is derived from four standard axioms (completeness, weak stochastic transitivity, continuity, and common consequence independence) and two relatively new axioms. The proposed model provides a better fit to experimental data than do existing models. The baseline model can be extended to other domains such as modeling variable consumer demand.

Such decisions are best captured through a model of probabilistic choice. Popular models [...]

In developing industries, firms have to decide whether and when to enter the market depending on the state of demand, existing firms in the industry, and the firm's capabilities. This paper investigates a model of increasing demand, in which firms decide when to enter the market anticipating the strategic behavior of other potential entrants, and the effects of entry on future potential entrants. This paper shows that the ability of early entry to deter future competitors' entry leads firms to enter the market at a rate faster than demand is expanding. If there is the potential for many firms to enter the market, firms may be less likely to enter because of future competitor entry to correct any market opportunities. If firms enter the market depending on their fixed capabilities rather than depending on the firm's circumstances at each moment in time, firms end up entering the market at a faster rate in the early periods.

In this paper, we consider the classical multifare, single-resource (leg) problem in revenue management for the case where demand information is limited. Our approach employs a competitive analysis, which guarantees a certain performance level under all possible demand scenarios. The only information required about the demand for each fare class is lower and upper bounds. We consider both competitive ratio and absolute regret performance criteria. For both performance criteria, we derive the best possible static policies, which employ booking limits that remain constant throughout the booking horizon. The optimal policies have the form of nested booking limits. Dynamic policies, which employ booking limits that may be adjusted at any time based on the history of bookings, are also obtained. We provide extensive computational experiments and compare our methods to existing ones. The results of the experiments demonstrate the effectiveness of these new robust methods.

Experts advise against rushing to optimization in RM without first fully implementing [...]

An important managerial question is the choice of the pricing rule. We study whether this choice depends on the uncertainty about the number of participating bidders by comparing expected revenues under discriminatory and uniform pricing within an auction model with affiliated values, stochastic number of bidders, and linear bidding strategies. We show that if uncertainty about the number of bidders is substantial, then the discriminatory pricing generates higher expected revenues than the uniform pricing. In particular, the first-price auction might generate higher revenues than the second-price auction. Therefore, uncertainty about the number of bidders is an important factor to consider when choosing the pricing rule. We also study whether eliminating this uncertainty, i.e., revealing the number of bidders, is in the seller's interests, and discuss the existence of an increasing symmetric equilibrium.

Problems such as price volatility have been observed in electric power markets. Demand-side participation is frequently offered asa potential solution by promising to increase market efficiency when hockey-stick-type offer curves are present. However, the individual end-consumer will surely value electricity differently, which makes demand-side participation difficult as a group and at a bus. In this paper demand is categorized into two groups: one that highly values reliability and one that does not. The two types are modeled separately and a new optimal bidding function is developed and tested based on this model. Index Terms--Bidding function, demand-side participation, interruptible load contracting, must-serve demand, price-based demand.

Measudring demand uncertainty is a key activity in supply chain planning, but it is difficult when demand history is unavailable, such as for new products. One method that can be [...]

Due to the oligopoly structure of the electricity markets and to the constraints imposed by the transmission network, the producers may exert market power by strategically bidding higher than their marginal costs. This brings market performance far from the perfect competition equilibrium, with higher market clearing price and extra surpluses obtained by the producers. Demand elasticity can significantly affect the market performance contributing to mitigate the strategic bidding behavior of the producers. Compared to other commodity markets, demand elasticity in the electricity markets is low, but even a small increase can result in appreciable improvement of the market performance. The network constraints of the power system play a specific role in determining the oligopoly equilibrium of the gaming behavior of the electricity producers. The model of supply function equilibrium is first applied to a simple three-bus test system for a conceptual analysis and then to a standard IEEE 30-bus test system. The effects of an increase of demand elasticity are assessed, resorting to a set of proper quantitative indexes. Index Terms--Demand elasticity, market power, supply function equilibrium.

A study about the impact of capacity and price over demand is examined as it is observed that several aspects of service level depend on capacity. In other words, simultaneous choice of product price and manufacturing capacity exists if demand is stochastic and service-level sensitive. The results of the study are analyzed.

Water is a singularly important natural resource, viewed differently from the rest because of its importance to wealth and prosperity. This paper examines issues in the literature of residential water demand, paying particular attention to data set, specification model, variables, and common econometric problems.

The sensitivity of M.K. Wohlgenant's findings to the type of shifts in demand and supply was examined. Instead of using parallel shifts, pivotal shifts were assumed. The results showed that the degree of substitutability was not the only factor for the ranking of producer gains. The type of shifts in supply and demand curves also played a role. Hence, incorrect policy recommendations for the allocation of checkoff funds would result if erroneous a priori generalization is used in shifts of demand and supply.

Product locations and prices have been determined through a spatial model under conditions of elastic consumer demand with a finite reservation price. Conditions wherein a two-stage equilibrium leads to maximal product differentiation with full market covering have also been derived. Results confirm that firms relax price competition by maximizing product differentiation when the price reservation is high.

The theoretical study of the various demand structures across countries on international trade reveals that demand partiality favoring a good may bear either a positive or negative effect on net trade. Moreover, national preferences impact net export favorably. Overall, in the empirical test of 17 Organization for Economic Cooperation and Development countries, there is a propensity for demand bias favoring a good to impact net exports positively.

From the Survey of Consumer Finances conducted in 1989 and 1992 a logit model was tested for demographic and financial influences on household decisions to utilize home equity line credit. Results indicate that among households with credit lines other than credit card lines or business lines, the choice of a home equity credit line in lieu of another type of check credit line is influenced principally by percentage of equity in the home, income, net worth, age of the borrower, and credit price. Several implications may be derived from this study. As the markets reflect more complete information about the low-risk attributes of this credit, the convenience as a payment mechanism, and the tax subsidy to homeowners, it is expected that home equity credit lines users will be distributed more evenly across income and wealth categories.

A proposed core model of macroeconomics has four major elements. Wages and prices develop according to Phillips-type equations, and are mostly estimated in the short run. Output is determined by demand in the short run. Aggregate demand is sensitive to interest, reacts to fiscal policy and responds to monetary policy which establishes short-term interest rates. Okun's law connects the variations in the unemployment rate to the growth in productivity.

This paper sets out to explore theoretically how a change in the distribution of disposable income affects the market demand for a good or service. With the help of only minimal information on the shape of the Engel curve and the transition from one distribution to the other, a variety of empirically relevant constellations are identified in which the size (or mean income) effect on market demand is counteracted by the distributional effect. Since the determining factors are expressed by relations between summary statistics, the results at the same time provide theoretically sound restrictions on economic approaches to market demand analysis., Changes in the distribution of disposable income have an effect on market demand for a good or service. There is an assortment of empirically relevant constellations in which the impact of the mean income on market demand is information based on the shape of the Engel curve and differences between income distributions.

Universally decentralised (UD) demand systems provide ways to analyze a wide range of household decision models that, otherwise, are not possible with unitary or the less decentralised collective models. Restrictions derived from derivatives of demand functions for different household allocation models allows testing between the different models.

The set of variables in a time series demand model in the form of the Almost Ideal Demand System are found to be I(1) with the demand equations forming a cointegrating system. The parameters of the cointegrating equations are estimated and tested using a 'triangular error correction' procedure. The null hypothesis of homogeneity with respect to prices and nominal income in the system cannot be rejected. Keywords: Conintegration; Demand system; Homogeneity

The study looks at price and income elasticities of demand for petroleum products in the Persian Gulf countries. The research used information gathered from 1970-91 and integrated to a partial adjustment model as basis. The results show that price and income are comparatively inelastic when seen on a short term basis, and that significant variations exist in these elasticities among cross-country and fuels.

This paper explores the idea that stockout avoidance motives together with serial correlation in demand and/or the backlogging of excess demand is sufficient to induce firms to behave so that the variance of production exceeds the variance of sales. We show that the idea holds under a wide range of circumstances facing firms, including additive as well as multiplicative demand uncertainty, a general form of serial correlation in demand, whether inventory and shortage costs apply, and whether payment occurs at order or delivery. The results greatly enhance the empirical relevance of the idea.

Results of experiments conducted on the ultimatum game have contradicted accepted economic theory. A study is conducted to demonstrate that experimental results of the ultimatum game are in accordance with the Law of Demand. This is proven by examining the salaries of major league baseball players and their marginal revenue.

The liberalization of international air travel laws in the North Atlantic air routes is analyzed with respect to its effect on consumer welfare and demand. Statistics from the US and five European countries were used to formulate a demand model. Results show that deregulation generally led to substantial increase in demand. Other variables such as accessibility of service routes and decreased fares did not affect demand as much. In this case, demand was considered to be relatively inelastic.

A model that includes the changes in the demand rate at random time points into the inventory planning decision is developed. These demand variations may arise out of economic recessions, start or end of labor strikes, and other events that result in an increase or decrease in the rate of demand. System-point level-crossing theory is used to generate expressions for the distribution and expected value of on-hand inventory, ordering rate and the expected total cost rate for a particular ordering policy. The model shows that, regardless of the actual demand rate, the cost penalty for employing the same stocking decision is very minimal if the disruption in demand is relatively insignificant. It also shows that are benefits if the inventory levels are adjusted in situations where there is a major demand disruption.

The effect of accelerated inflation on the output of manufacturing firms is analyzed. Test data is provided by a sample of Australian manufacturing companies. Results show that manufacturers will not readily respond to changes in demand during times of rapidly rising inflation. Other factors that influence production are the fluctuations in price changes and variability of import penetration ratio.

Market concentration and excess demand were both found to be linked with higher private prices for nursing home care. This was gleaned from an investigation of the effects of market concentration and excess demand on the prices charged by nursing homes to private patients. These findings indicate a policy conflict between the objective of certificate of need policy and antitrust laws.
