Characterizations of bivariate distributions using concomitants of record values

In this paper, we consider a family of bivariate distributions which is a generalization of the Morgenstern family of bivariate distributions. We have derived some properties of concomitants of record values which characterize this generalized class of distributions. The role of concomitants of record values in the unique determination of the parent bivariate distribution has been established. We have also derived properties of concomitants of record values which characterize each of the following families viz Morgenstern family, bivariate Pareto family and a generalized Gumbel’s family of bivariate distributions. Some applications of the characterization results are discussed and important conclusions based on the characterization results are drawn.     

Social identity salience: Effects on identity‐based brand choices of Hispanic consumers

The purpose of this study was to examine the combinatorial effects of enduring and momentary mechanisms of cultural identity salience on identity‐based apparel brand choices of three Hispanic acculturation segments (Hispanic‐dominant, mainstream‐dominant, and balanced‐bicultural). The hypotheses were empirically tested among Hispanic students at a midwestern university in the U.S. employing a two‐session online experiment. Results revealed that the influence of cultural primes (momentary salience of the cultural identity) on subsequent brand choices of Hispanic consumers is moderated by their bidimensional acculturation (enduring salience of the cultural identity). As posited, the current study found that the same cultural primes had differential effects among the three Hispanic acculturation segments, with the largest effect size among the balanced‐bicultural segment. Specifically, the results indicated that Hispanic‐dominant and mainstream‐dominant consumers were less responsive to cultural cues in the environment and were less likely to demonstrate significant preference shifts in response to cultural primes. However, balanced‐bicultural consumers demonstrated significant shifts in their attitudes and purchase intent for Hispanic and mainstream apparel brands when exposed to cultural primes, such that their brand choices assimilated toward the primed identity. Results are discussed in the context of social identity theory, the self‐stereotyping process, cultural frame shifting, and the bidimensional acculturation model. © 2010 Wiley Periodicals, Inc.     

Competition,strategic delegation and delay in technology adoption

This paper examines how strategic managerial delegation affects firms' timing of adoption of a new technology under different modes of product market competition. It demonstrates that strategic delegation has differential impacts on adoption dates under Cournot and Bertrand competitions. Strategic delegation with ‘own-performance’-based incentive schemes always leads to early adoption in markets with Bertrand competition compared to that under no-delegation, but not necessarily so in markets with Cournot competition. It also shows that under strategic delegation with ‘own-performance’-based incentive schemes, adoption occurs earlier (later) in markets with Cournot competition than in markets with Bertrand competition, if the degree of product differentiation is high (low). In contrast, under strategic delegation with ‘relative-performance’-based incentive schemes, adoption dates do not differ across markets with different modes of competition. It also analyses implications of firms' choice over types of managerial incentive schemes on the speed of diffusion of new technology.     

Will a matchmaker invite her potential rival in?

This paper analyzes optimal strategies of an incumbent intermediary, who matches agents on the two sides of a market, in the presence of entry threat under alternative scenarios. It shows that, when entry is free, strategic entry accommodation is the optimal choice of the incumbent—not entry deterrence, unless the variation in agents' types is small. Entry accommodation remains optimal for the incumbent for a wide range of parametric configurations even when there is a fixed cost of entry. These results are in sharp contrast to the predictions of existing models of entry.     

On the diffusion of toilets as bottom of the pyramid innovation: Lessons from sanitation entrepreneurs

There is an emerging body of literature on product innovations for the poor at the bottom of the income pyramid. However, there is little on why delivery systems succeed or fail in this context and the present paper attempts to fill this void by examining why and how sanitation entrepreneurs are succeeding in India to diffuse toilets — an innovation for rural households, which never had access to one before. The literature is analyzed and confronted with the actual field practices. We demonstrate that the common thread that unifies progressive sanitation entrepreneurs is their adoption of a ‘market based approach’. There are market failures stemming from the demand side due to problems in expression of demand and its mismatch with the perceived value of the innovation. In response, sanitation entrepreneurs go beyond the standard linear model of assessing need and appropriateness of technology. They create innovations in ‘technological design’ as well as in the ‘delivery platforms’ to include practices for ‘accompaniment’, ‘sustainable maintenance’ and ‘generation of knowledge'. Thus, they make-up for sluggish or missing markets and informational asymmetries to ensure sustained use of toilets.     

Identity salience and shifts in product preferences of Hispanic consumers: Cultural relevance of product attributes as a moderator

Culturally relevant products, services, and communications play a crucial role in the success of ethnic targeted marketing. Employing a bi-dimensional approach, two studies examine how cultural relevance of product attributes interacts with acculturation level, and situational and contextual factors to affect product attribute evaluations (PAE) of Hispanic consumers. Across both studies, cultural relevance had main effects on PAE. In Study 1, cultural relevance interacted with cultural situations to affect PAE. Hispanic consumers evaluated Hispanic (or Mainstream) relevant product attributes more favorably when exposed to a Hispanic (or Mainstream) cultural situation. In Study 2, cultural relevance interacted independently with cultural primes and acculturation level to significantly affect PAE. PAE shifted as a result of cultural primes and moved toward being typical to the activated cultural identity. Results are discussed in the context of consumer acculturation, social identity-based consumption, biculturalism, and cultural frame shifting.     

Rising prices and coping strategies of urban families in India

This study examines how Indian urban households coped with rising prices over the period 1995–1996 to 1999–2000. It provides evidence of cost of living indices and the coping strategies of urban households belonging to different income groups. Although there has been a lively debate on inflation and related issues, most of the studies were macro studies, which have not paid explicit attention to the impact of rising prices on the coping and financial management responses of the affected families. This paper is a part of a larger cross‐sectional study on the impact of rising prices on quality of life and financial management practices of Indian urban households belonging to five different income groups. This paper provides the evidence on cost of living indices and the coping strategies adopted by these households to combat an otherwise hostile economic environment. It found that the impact of cost of living indices differs across different income groups depending upon the composition of the consumption basket and the proportion of expenditure incurred on specific items of that basket. It is also observed that rational responses of households played an important role in coping with increased cost of living. The evidence suggests that a wide range of coping strategies is adopted by households such as consumption reallocation and seeking increased earning opportunities as part of their backward and forward coping strategies.     

Service levels for priority and nonpriority products with a common component

This paper refers to an article by Baker, recently published in the Journal of Operations Management. We point out an error, and provide correction, in the calculation of service level for a non priority product when a priority product and the nonpriority product share a common component.     

Chain Coordination Mechanisms and Concerns in the Sugar Industry in Punjab,India

Based upon primary data, this study carried out for the Punjab state indicated that mutual interdependences of the chain partners coupled with the announcement of SMP/SAP for cane have facilitated chain coordination. This ensures timely cane supplies to sugar mills as well as cane disposal and payments to farmers. Besides the cyclical nature of industry that particularly during its downward phase adversely affects cane supplies, its production has not kept pace with capacity expansion. So a continuous upward revision in SAPs has diverted cane supplies to the industry from the gur industry. And, private mills owing to comparatively greater market orientation have steamed ahead of state owned cooperative mills which are beset with several concerns.     

Supply Chain Management in a Private Farming Vis-à-Vis Cooperative Processing and Distribution Environment of Dairy Sector in India

Organized segment of dairy sector was hitherto dominated by the cooperative sector that established a structured and three-tiered organizational hierarchy, procured milk from small-scale farms, processed and distributed milk and milk products. With the liberalization of India's economy and market entry by the private sector, new dynamics have emerged. These include increased supplies of a greater variety of value-added products and increased inter-firm competition with companies and supporting their sales development with integrated marketing initiatives. This fostered greater attention to branding, product positioning and product differentiation with intense price discounting for some products. In response to these challenges, the State cooperatives have started to integrate their operations in areas such as procurement of supplies, logistics, manufacturing, distribution and inventory management. However, these face a major constraint regarding the sufficient availability of milk supplies over space and time while due to political interferences, excess staff adds to the administrative costs therby inefficiencies in its operations and losses results.
