A central aim <strong>of</strong> marketing managers is the optimal allocation <strong>of</strong> budgets across customer<br />

segments and market regions. Often, these allocation decisions are subject to<br />

interpersonal contagion. However, sales response models traditionally assume customers’<br />

independence. We present a method for incorporating spatial spillovers into<br />

sales response functions and a subsequent optimization procedure that allows for<br />

allocating sales/pr<strong>of</strong>it optimizing budgets across segments and regions while accounting<br />

for spillover effects. Employing hierarchical Bayesian estimation, our results from<br />

an empirical application to a pharmaceutical panel dataset indicate that substantive<br />

additional sales/pr<strong>of</strong>its can be ex-pected due to incorporating spillovers and thereby<br />

improving allocation.<br />

1 - Co-creation <strong>of</strong> Social Value in an Online Brand Community<br />

This study explores one <strong>of</strong> the core features <strong>of</strong> a brand community, its social aspects<br />

which drive value co-creation among members <strong>of</strong> the community. Value co-creation<br />

emphasizes the dual role <strong>of</strong> customers as consumer and creator <strong>of</strong> value through<br />

interactions with the company and other customers, sharing experience on products<br />

and brands. This service-dominant (S-D) logic has not been adopted to examine<br />

brand communities which serve as an ideal platform for these interacting processes to<br />

take place. In this study, we try to examine empirically how iPhone users who are<br />

members <strong>of</strong> an online iPhone community interact and derive new values from<br />

community participation. It provides insights to practitioners on the value co-creation<br />

dimension <strong>of</strong> brand communities and gives future research direction on the social<br />

aspect <strong>of</strong> online marketing.<br />

2 - What is There to ‘Like’ About Facebook?<br />

Social media and social networks (like MySpace, Facebook, and LinkedIn) have<br />

proliferated and grown exponentially over the past decade or so. Even Hollywood has<br />

taken notice with a recent movie (“The Social Network”) tracing the origins <strong>of</strong><br />

Facebook. There has been a tremendous interest in understanding aspects <strong>of</strong> the<br />

social network phenomenon by all manner <strong>of</strong> organizations, business in particular.<br />

Articles have been published in fields as diverse as educational technology (Baran<br />

2010) , managerial psychology (Klumpfer and Rosen 2009), human resources<br />

(Elsweig and Peoples 2009), information technology (McAfee 2010, Palvia and<br />

Pancaro 2010, Venkatraman 2010), marketing communication (Zhang 2010),<br />

intellectual property (Steinman and Hawkins 2010), academic performance<br />

(Kirschner and Karpinski 2010, Yu et al 2010), among many others. Our primary<br />

interest is in understanding the behavior <strong>of</strong> ‘liking’ on Facebook. We collect and<br />

analyze survey information from a fairly large sample <strong>of</strong> respondents who self<br />

identify themselves as ‘liking’ a business or organization. In the study being<br />

presented, we compare characteristics and behavior <strong>of</strong> two samples; those that have<br />

actually experienced the good or service being provided by the organization they<br />

‘like’ vs. those who have not had such experience. Preliminary results suggest there<br />

are interesting differences between the groups in measures pertaining to identity,<br />

norms, involvement, and word-<strong>of</strong>-mouth behavior, some <strong>of</strong> which appear to be<br />

counter-intuitive.<br />

3 - Too Much or Not Enough - How the Degree <strong>of</strong> Interpersonal<br />

Similarity Forces Compliance with Requests<br />

Imagine you are asked for participation in a survey. Would your willingness to<br />

comply depend on characteristics <strong>of</strong> the requester? Would you be more likely to<br />

answer when there is a similarity between you and the requester? And, particularly,<br />

would the degree <strong>of</strong> similarity affect your willingness? Many studies provide support<br />

for the persuasive role <strong>of</strong> similarity on willingness to comply. When people share<br />

similarities, they feel socially connected that is enough to increase compliance with<br />

requests. However, contrary to that literature, research on uniqueness empathizes<br />

humans’ innate drive for uniqueness that leads them to avoid too much similarity.<br />

Therefore, we experimentally investigate whether the degree <strong>of</strong> similarity,<br />

manipulated by the first name <strong>of</strong> the requester, influences compliance with a request.<br />

600 marketing and sales managers were invited to participate in an online survey.<br />

They were randomly assigned to one <strong>of</strong> three conditions: one third <strong>of</strong> the participants<br />

were invited by a person with the same first name (“high similarity”), the second<br />

third received the request by a person with same first name initials (“low similarity”),<br />

and the remaining third was contacted by a person with a completely different first<br />

name (“no similarity”). The conditions were identical with the exception <strong>of</strong> the name<br />

that appeared as the requester <strong>of</strong> the invitation. The results support our assumption<br />

<strong>of</strong> an inverted u-shaped relationship between the degree <strong>of</strong> similarity and humans’<br />

willingness to comply. Persons with identical initials were significantly more likely to<br />

participate in the survey than both those who received the request by a person with<br />

different initials and those with same first name. We find no difference between high<br />

and no similarity conditions.<br />

4 - User Personality, Perceived Benefits and Usage Intensity <strong>of</strong> Social<br />

Networking Sites: An Indian Study<br />

Social Networking Sites (SNS) such as Orkut, Facebook and LinkedIn have attracted<br />

millions <strong>of</strong> users around the globe. While studies have been conducted to explore the<br />

user motives to participate in such virtual communities, research linking the impact<br />

<strong>of</strong> the personality and usage intensity is scantily done. Even so, the available studies<br />

indicate mixed evidence between user personality traits (such as extraversion,<br />

agreeableness, openness to experience, neuroticism and conscientiousness) and the<br />

SNS usage. Research linking user personality and SNS usage intensity is expected to<br />

have major strategic policy implications for marketers in strengthening the<br />

advertisement and promotions <strong>of</strong> their products as SNS are emerging as attractive<br />

medium for marketers to reach out to the target audience. This paper based on<br />

empirical research conducted among the youth (n=203) in India explores the impact<br />

<strong>of</strong> user personality traits on the SNS usage intensity, with perceived benefits in using<br />

SNS as a mediator. Mediation regression analysis <strong>of</strong> the data indicates that user<br />

personality trait has direct and indirect effect on the usage intensity <strong>of</strong> SNS. Further,<br />

it is observed that the relationship between user personality, perceived SNS benefits<br />

and the usage <strong>of</strong> SNS varies for male and female respondents.<br />

1 - Retailer Brand: To Keep it Private or Not?<br />

A retailer with its own brand can either make its brand private by selling through<br />

only the retailer’s own stores or make the brand public by selling through another<br />

competing retailer. In the first case, the retailer brand becomes a private label; in the<br />

second case, the retailer brand becomes more like a national brand. In this paper, we<br />

study when a retailer should keep its brand private and when not, and the<br />

consequent implications for distribution channel members. We find conditions under<br />

which the retailer should keep its brand private or sell it through another retailer. We<br />

show that selling through a competing retailer can help expand a retailer’s market.<br />

However, it also has significant implications for the competition between the retailers,<br />

the distribution channel, and consumer welfare.<br />

2 - Retailer Brand Introduction with Consumer Evaluation<br />

In the market place, there is a growing trend for retailers to introduce retailer brands<br />

(store brands) to complement manufacturer brands and enrich the in-store product<br />

variety. In this paper, we study the effects <strong>of</strong> a retailer brand on the pr<strong>of</strong>itability <strong>of</strong> a<br />

manufacturer and a retailer when consumers do not have full information about the<br />

products and have to incur a cost to evaluate the brands. We show that a<br />

manufacturer can benefit from a retailer brand, and the benefit may increase with<br />

the rising quality <strong>of</strong> the retailer brand. This happens when the introduction <strong>of</strong> a<br />

retailer brand motivates the retailer to induce consumer evaluation and the<br />

manufacturer can take advantage <strong>of</strong> that to charge a high wholesale price. Depending<br />

on the level <strong>of</strong> consumer evaluation cost, either a decentralized channel or a<br />

centralized channel can <strong>of</strong>fer more product varieties. Furthermore, at certain<br />

evaluation costs, consumers can be better <strong>of</strong>f in a decentralized channel than in a<br />

centralized one.
