Benefits to local communities from community conservancies in Namibia: an assessment

This article evaluates the benefits of community-based activities in wildlife conservancies in Namibia by asking three questions: Do community conservancies contribute to an increase in household welfare? Are such programmes pro-poor; that is, do they improve welfare more for poorer households than for the less poor? Does participation in conservancy increase household welfare more for participants than non-participants? This study bases the analyses on a 2002 survey covering seven conservancies and 1192 households. The results suggest that community conservancies have a positive impact on household welfare. The authors also conclude that this impact is poverty-neutral in some regions and pro-poor in others. Further, welfare benefits from conservancies appear to be fairly evenly distributed between participant and non-participant households.     

Endogenous effort in a Dynamic Model of Union–Firm Interaction

This paper studies the implications of union deviation by reducing effort in the context of a repeated game model. We find that a failure to account for the possibility of union deviation may lead to an overestimation of the possibility of cooperation. In contrast to the existing literature, we find that unions may reach the efficient outcome despite wage hikes because they work harder under cooperation. We also find that when effort is an endogenous variable, the cooperative wage is likely to be higher than otherwise. Finally, our model predicts that if the union alone deviates, effort will fall as the endgame approaches. However, wages could either rise or fall.     

Representing Heterogeneity in Consumer Response Models 1996 Choice Conference Participants

We define sources of heterogeneity in consumer utility functions relatedto individual differences in response tendencies, drivers of utility, formof the consumer utility function, perceptions of attributes, statedependencies, and stochasticity. A variety of alternative modelingapproaches are reviewed that accommodate subsets of these various sourcesincluding clusterwise regression, latent structure models, compounddistributions, random coefficients models, etc. We conclude by defining anumber of promising research areas in this field.     

Customer relationship management in competitive environments: The positive implications of a short-term focus

Researchers and business thought leaders have emphasized that firms must think and act with a long-term horizon when managing customer relationships. We demonstrate that, in contrast to this widely held view, profits in competitive environments may be maximized when firms ignore the future and instead maximize period-by-period profits from customers. Intuitively, while a long-term focus yields more loyal customers, it greatly increases short-term price competition to gain and keep customers. Consequently, overall firm profits and customer lifetime value may be lower when firms directly maximize multi-period profits from customers. Specifically, we analyze a model with segment-level pricing where firms in a duopoly can choose between period-by-period and multi-period profit maximization and demonstrate that, in many cases, a symmetric focus on period-by-period profit maximization emerges as the Pareto-dominant Nash equilibrium. We extend the model in two directions. First, we demonstrate that this superiority of the short-term focus endures even when a revenue expansion effect applies—that is, when customer loyalty leads to enhanced revenues. Second, we examine the case where customers are strategic and incorporate the long-term implications of their choices into their decision-making. Here we demonstrate that it may pay for firms to be myopic even when customers are strategic. The focus on multi-period surplus makes customers less price sensitive to price variations at the early stage of the game. Consequently, the focus on maximizing period-by-period profits enables the firms to charge higher upfront prices and leverage this lower price sensitivity into higher profits. Overall, our results highlight the paradox that, when it comes to managing customer relationships in competitive environments, a short-term focus may constitute the optimal long-term strategy.

Structural Applications of the Discrete Choice Model

A growing body of empirical literature uses structurally-derived economic models to study the nature of competition and to measure explicitly the economic impact of strategic policies. While several approaches have been proposed, the discrete choice demand system has experienced wide usage. The heterogeneous, or mixed, logit in particular has been widely applied due to its parsimonious structure and its ability to capture flexibly substitution patterns for a large number of differentiated products.We outline the derivation of the heterogeneous logit demand system. We then present a number of applications of such models to various data sources. Finally, we conclude with a discussion of directions for future research in this area.     

Beliefs,attitudes and behaviour towards Web advertising

To examine Web users' beliefs, attitudes and behaviour towards Web advertising, Pollay and Mittal's (1993) belief model is tested via structural equation modelling. The results suggest the model is a robust Web advertising effectiveness measurement tool. Underlying the study are the hypotheses that Web users' attitudes towards Web advertising are a function of several belief factors and influence users' behavioural intention. Results indicate the belief factors—product information, hedonic pleasure, and social role and image—related positively to subjects' attitudes towards Web advertising. Web users' beliefs about materialism, falsity/no sense and value corruption related negatively to their attitudes towards Web advertising. Web advertising attitudes impacted on reported behaviour towards Web advertising such that the more positive Web users' attitudes were towards Web advertising, the greater the likelihood that they would respond favourably to Web ads. In addition, the higher the respondents' income and education, the more negative their reported behaviour towards Web advertising.     

Developing a framework to improve retail category management through category captain arrangements

Manufacturers and retailers have divergent profit objectives. A manufacturer wants to maximize the profits of its own brands. The retailer, on the other hand, wants to maximize the profit of the entire product category. In spite of these apparently diverging profit objectives, both manufacturers and retailers are increasingly realizing that profit margins of both can be increased through cooperation rather than confrontation. Category management is one such cooperative strategy that often involves the appointment of a leading manufacturer as the “category captain”. A category captain advises the retailer on the best way to price, display, and promote products in a category, including those of the competitors. This arrangement, therefore, ensures retail efficiency but raises doubt about possible misuse of power by the category captain to circumvent fair competition. In this paper, we outline the antitrust concerns about this arrangement, and provide a framework that effectively addresses these concerns.     

Perfect competition in an oligopoly (including bilateral monopoly)

We show that if limit orders are required to vary smoothly, then strategic (Nash) equilibria of the double auction mechanism yield competitive (Walras) allocations. It is not necessary to have competitors on any side of any market: smooth trading is a substitute for price wars. In particular, Nash equilibria are Walrasian even in a bilateral monopoly.
