This article explains how the metric, Customer Value Added (CVA), can be applied to develop effective marketing and branding strategies. Strategies that are successful against competitors should focus on creating CVA that is greater than those produced by competitors. To do so, one must first regularly measure and monitor CVA by examining its components, perceived value and variable costs per unit. Next, one must develop strategies and tactics to increase CVA effectively and efficiently. In the long run, the organization that succeeds in achieving and maintaining the highest CVA wins.

Organized groups face a fundamental problem of how to distribute resources fairly. We found people view it as less fair to distribute resources equally when the allocated resource invokes the market by being a medium of exchange than when the allocated resource is a good that holds value in use. These differences in fairness can be attributed to being a medium of exchange, and not to other essential properties of money (i.e., being a unit of account or a store of value).

The authors propose that gender differences in negotiations reflect women's contextually contingent impression management strategies. They argue that the same behavior, bargaining assertively, is construed as congruent with female gender roles in some contexts yet incongruent in other contexts. Further, women take this contextual variation into account, adjusting their bargaining behavior to manage social impressions. A particularly important contextual variable is advocacy—whether bargaining on one's own behalf versus on another's behalf.

This article complements the structural New Keynesian macro framework with a no-arbitrage affine term structure model. Whereas our methodology is general, we focus on an extended macro model with unobservable processes for the inflation target and the natural rate of output that are filtered from macro and term structure data. We find that term structure information helps generate large and significant parameters governing the monetary policy transmission mechanism. Our model also delivers strong contemporaneous responses of the entire term structure to various macroeconomic shocks.

After decades of research highlighting the fallibility of first impressions, recent years have featured reports of valid impressions based on surprisingly limited information, such as photos and short videos. Yet beneath mean levels of accuracy lies tremendous variance—some snap judgments are well-founded, others wrongheaded. An essential question for perceivers, therefore, is whether and when to trust their initial intuitions about others.

The actions of different agents sometimes reinforce each other. Examples are network effects and the threshold models used by sociologists as well as Harvey Leibensteins's "bandwagon effects." We model such situations as a game with increasing differences, and show that tipping of equilibria, cascading and clubs with entrapment are natural consequences of this mutual reinforcement. If there are several equilibria, one of which Pareto dominates, then the inefficient equilibria can be tipped to the efficient one, a result of interest in the context of coordination problems.

This paper reports a positive and statistically significant relation between short-term discount rates elicited with a monetary and a primary reward (chocolate). This finding suggests that high short-term discount rates are related to an underling individual trait.

Why companies have had difficulties determining marketing ROI and how they should approach evaluating marketing ROI. (Reprinted from Columbia Ideas at Work, "Many Happy Returns on Marketing," 8/31/2009, pp. 1-2.)

In every period, an aggressive country seeks concessions from a non-aggressive country with private information about their cost. The aggressive country can force concessions via war, and both countries suffer from limited commitment.We characterize the efficient sequential equilibria. We show that war is necessary to sustain peace and that temporary wars can emerge because of the coarseness of public information. In the long run, temporary wars can be sustained only if countries are patient, if the cost of war is large, and if the cost of concessions is low.

We investigate whether accounting discretion is (i) abused by opportunistic managers who exploit lax governance structures, or (ii) used by managers in a manner consistent with efficient contracting and shareholder value-maximization. Prior research documents an association between accounting discretion and poor governance quality and concludes that such evidence is consistent with abuse of the latitude allowed by accounting rules.

Recent theoretical work has suggested a number of potentially important factors in causing incomplete pass-through of exchange rates to prices, including markup adjustment, local costs and barriers to price adjustment. We empirically analyze the determinants of incomplete pass-through in the coffee industry. The observed pass-through in this industry replicates key features of pass-through documented in aggregate data: prices respond sluggishly and incompletely to changes in costs.

This paper documents frequent attempts by activist arbitrageurs to open-end discounted closed-end funds, particularly after the 1992 proxy reform which reduced the costs of communication among shareholders. Open-ending attempts have a substantial effect on discounts, reducing them, on average, to half of their original level. The size of the discount is a major determinant of whether a fund gets attacked. Other important factors include the costs of communication among shareholders and the governance structure of the targeted fund.

Identity movements rely on a shared "we-feeling" amongst a community of participants. In turn, such shared identities are possible when movement participants can self-categorize themselves as belonging to one group. We address a debate as to whether community diversity enhances or impedes such protests, and investigate the role of racial diversity since it is a simple, accessible, and visible basis of community diversity and social categorization.

Financial crises appear to be a common and fairly constant feature of the economic cycle. Banking crises, a distinct subset of financial crises, consist either of panics, moments of temporary confusion about the unobservable incidence across the financial system of observable aggregate shocks, or severe waves of bank failures which result in aggregate negative net worth of failed banks in excess of one percent of GDP.

The article offers the authors' views on expatriate management programs and the benefits from executives interacting with the people and institutions of the host country. The idea that international experience or interaction between foreign managers and local people will help managers become more creative, entrepreneurial, and successful is discussed. The concept of integrative complexity in bi-cultural managers which enhances job performance is mentioned.

We study a capacity sizing problem in a service system that is modeled as a single-class queue with multiple servers and where customers may renege while waiting for service. A salient feature of the model is that the mean arrival rate of work is random (in practice this is a typical consequence of forecasting errors). The paper elucidates the impact of uncertainty on the nature of capacity prescriptions, and relates these to well established rules-of-thumb such as the square root safety staffing principle.

We study scheduling of multimedia traffic on the downlink of a wireless communication system. We examine a scenario where multimedia packets are associated with strict deadlines and are equivalent to lost packets if they arrive after their associated deadlines. Lost packets result in degradation of playout quality at the receiver, which is quantified in terms of the "distortion cost" associated with each packet. Our goal is to design a scheduler which minimizes the aggregate distortion cost over all receivers. We study the scheduling problem in a dynamic programming (DP) framework.

Discrete choice models are appealing for airline revenue management (RM) because they offer a means to profitably exploit preferences for attributes such as time of day, routing, brand, and price. They are also good at modeling demand for unrestricted fare class structures, which are widespread throughout the industry. However, there is little empirical research on the practicality and effectiveness of choice-based RM models. Toward this end, we report the results of a study of choice-based RM conducted with a major U.S. airline.

Using data on repurchase agreements by primary securities dealers, we show that three classes of securities (Treasury securities, securities issued by government-sponsored agencies, and mortgage-backed securities) can be formally ranked in terms of their collateral values in the general collateral (GC) market.

Four studies examined the relationship between counterfactual origins — thoughts about how the beginning of organizations, countries, and social connections might have turned out differently — and increased feelings of commitment to those institutions and connections. Study 1 found that counterfactually reflecting on the origins of one's country increases patriotism. Study 2 extended this finding to organizational commitment and examined the mediating role of poignancy.

Blackmail, a wonderfully curious offense, is the favorite of clever criminal law theorists. It criminalizes the threat to do something that would not be criminal if one did it. There exists a rich literature on the issue, with many prominent legal scholars offering their accounts. Each theorist has his own explanation as to why the blackmail offense exists. Most theories seek to justify the position that blackmail is a moral wrong and claim to offer an account that reflects widely shared moral intuitions.

The intensity of modern business has increased pressure for innovation, which places greater emphasis on creativity. This article explores one of the central sites of creativity in the American corporate world, the advertising agency. We examine how creativity in agencies is managed, controlled, and channeled to produce advertisements. We contend that the brand advertised and the agency’s creative collaborations have properties of ritual symbols and that rituals mediate tension inherent in two forces, stability and change, which define the brand and the advertising collaboration.

We argue that differences between the landscapes of influence situations in Indian and American societies induce Indians to accommodate to others more often than Americans. To investigate cultural differences in situation-scapes, we sampled interpersonal influence situations occurring in India and the United States from both the influencee's (Study 1) and the influencer's (Study 2) perspectives. We found that Indian influence situations were dramatically more likely than U.S. situations to feature other-serving motives and to result in positive consequences for the relationship.

A fundamental challenge facing social perceivers is identifying the cause underlying other people’s behavior. Evidence indicates that East Asian perceivers are more likely than Western perceivers to reference the social context when attributing a cause to a target person’s actions. One outstanding question is whether this reflects a culture’s influence on automatic or on controlled components of causal attribution.

The Pampas of Argentina have shown some of the most consistently increasing trends in precipitation during the 20th century. The rainfall increase has partly contributed to a significant expansion of agricultural area, particularly in climatically marginal regions of the Pampas. However, it is unclear if current agricultural production systems, which evolved partly in response to enhanced climate conditions, may remain viable if (as entirely possible) climate reverts to a drier epoch.

The authors test methods, based on cognitively simple decision rules, that predict which products consumers select for their consideration sets. Drawing on qualitative research, the authors propose disjunctions-of-conjunctions (DOC) decision rules that generalize well-studied decision models, such as disjunctive, conjunctive, lexicographic, and subset conjunctive rules. They propose two machine-learning methods to estimate cognitively simple DOC rules. They observe consumers' consideration sets for global positioning systems for both calibration and validation data.

By reducing the threat of a hostile takeover, business combination (BC) laws weaken corporate governance and increase the opportunity for managerial slack. Consistent with the notion that competition mitigates managerial slack, we find that while firms in non-competitive industries experience a significant drop in operating performance after the laws' passage, firms in competitive industries experience no significant effect. When we examine which agency problem competition mitigates, we find evidence in support of a "quiet-life" hypothesis.

Purpose: To assess whether perspective-taking, which researchers in other fields have shown to induce empathy, improves patient satisfaction in encounters between student–clinicians and standardized patients (SPs).

Automobile manufacturers in the U.S. supply chain exhibit significant differences in their days-of-supply of finished vehicles (average inventory divided by average daily sales rate). For example, from 1995 to 2004, Toyota consistently carried approximately 30 fewer days-of-supply than General Motors. This suggests that Toyota's well-documented advantage in manufacturing efficiency, product design and upstream supply chain management extends to their finished-goods inventory in their downstream supply chain from their assembly plants to their dealerships.

We consider the problem of integrating spatial amenities into locational equilibrium models with multiple jurisdictions. We provide sufficient conditions under which models that assume a single housing price in each community continue to apply in the presence of location-specific amenities that vary both within and across communities. If these conditions are satisfied, the models, estimation methods, and results in Epple and Sieg (1999) are valid in the presence of (potentially unobserved) location-specific amenities.

The U.S. pharmaceutical industry spent upwards of $18 billion on marketing drugs in 2007. Detailing and drug sampling activities account for the bulk of this spending. To stay competitive, pharmaceutical managers need to maximize the return on these marketing investments by determining which physicians to target, when, and how to target them. In this paper, we present a two-stage approach for dynamically allocating detailing and sampling activities across physicians to maximize long-run profitability.
