3 - Supply Chain Power and Store Brand

Ruixia Shi, Jun Zhang
This paper relates a retailer’s store brand strategy to the relative powers of
channel members and offers a new explanation for the differences in retailers’
store brand strategies. Our analysis shows that store brands become less appealing
to a retailer as it becomes more powerful.
4 - Consumer Preference Mismatch and Channel Choice Decisions
under Competition

We consider a product consisting of two components sold by two firms. A
product/firm is integrated when both components are designed by a single firm,
and is non-integrated otherwise. The consumers choose to purchase a product
that better matches the specifications of their ideal product. Using a duopoly
model, we study the effects of consumer preference mismatch on channel
integration strategies.

1 - An Analysis of Menus of Multi-Part Tariffs
Ryan Choi, PhD Candidate, UC Irvine, 6219 Adobe Circle, Irvine,
CA, 92617, United States of America,
This paper study which characteristics of three-part tariffs make the seller more
profitable than two-part tariffs. Given a full extraction of low type segment’s
surplus, the seller can extract more of high type surpluses, whose magnitude is
dependent on both of the level of quantity allowances and the fixed fee for high
type consumers. With 3PTs, firms earn more rent from the high type, and so
offers both high and low contracts regardless of the taste parameter and of the
low type proportion.
2 - Research and Practice – Friends of Foes? Perceptions of
Marketing Academicians and Practitioners.

This research is more of an exploratory nature that focuses initially on
precipitating the perceptions of marketing academicians as well as marketing
practitioners regarding the existence of the research practice gap using diffusion
of innovations theory. The results indicated that generally both agree on the
prevalence of the gap. Further, their perception is the same for discovery and
translations stage whereas it differs for the dissemination and change stage.
3 - Customer Commitment in Customer Churn Prediction
Huili Liu, Beijing University of Posts and Telecommunications,
Xitucheng Road, No 10, Beijing, BJ, 100876, China,
We present a customer commitment model to predict the customer churn. Instead
of probability method, we use consumer learning to get the customer
commitment from his/her purchase history, and then use it to predict the
customer churn. In comparison to existing models, we consider the customer
commitment model is more feasible with an accurate prediction. Thereby we
provide a new insight into the customer base analysis.
4 - Socio-economic Class Difference in Movie Consumption
Among Pre-adolescents
Saima Husain, Lecturer, Institute of Business Administration,
University Campus, University Road, Karachi, Si, Pakistan,
This research uses the laddering technique, in semi-structured in depth
interviews, to study hierarchical constructs explaining personal value system that
drive movie consumption behaviour among children aged 9 - 12 years. Young
informants were recruited from different socio economic class (SEC) households
in Pakistan. Findings show that children from higher SECs are significantly
different in the type of movie selection, consumption setting and medium used
for movie consumption.
5 - An Empirical Study to Examine Consumer Behavior towards
Luxury Brands in Pakistan
Faryal Salman, Assistant Professor, SZABIST, 90 Clifton, Karachi,
Karachi, Pakistan, Usman Warraich
Current study seeks to expand an understanding of consumer behavior towards
branded goods. The data for this exploratory study was collected from urban
youth of Pakistan. The study postulates significant relationship between consumer
behavior and the predictors for various product categories. Regression analysis
shows that these variables pose the positive impact on the buying behavior (p
value (0.05) and this model shows R2 of 0.73.

1 - Determinants of Distribution Channel Choice in Pharmaceutical
Industry – Specialty Drugs
Liang (Leon) Xu, University of Missouri-St. Louis, St. Louis, MO,
United States of America, , Vidya Mani, Hui Zhao
We use privately collected multi-year transaction data to study determinants of
the choice of distribution channels for specialty and non-specialty drugs. Further,
we explore how this channel choice explains observed variations in supply chain
metrics in this industry.
2 - Transforming Drug Development via System
Computational Modeling
Jinha Lee, Georgia Institute of Technology, 755 Ferst Dr. NW,
Atlanta, GA, United States of America,
Eva Lee
We describe the firstin-silico drug design system model to accelerate drug
discovery. The model spans preclinical, clinical, IND and NDA tasks; and allows
global risk analysis. It identifies bottlenecks, and performs system optimization
that offers a holistic view of discovery pathways. Rapid development is achieved
through parallel processes that shorten critical paths from start to registration of a
new drug. The generalizable design allows rapid testing, and minimizes risk, cost,
and time.
3 - Operational Performance Evaluation of Reverse Referral
Partnership in the Chinese Healthcare System
Nan Kong, Associate Professor, Purdue University, 206 S. Martin
Jischke Dr., West Lafayette, IN, United States of America,
Quanlin Li, Na Li, Zhibin Jiang
Reverse referral of patients from upper-level hospitals to lower-level hospitals
after their acute care, has been promoted in the tiered Chinese care system to
alleviate resource pressure at high-level hospitals and balance utilizations
throughout the system. However, it remains unclear how to implement reverse
referral partnerships given the conflicting interests. We develop a two-level
queuing network model to capture patient flows and derive analytical results on
queueing performance measures. Our work is expected to guide the
establishment of hospital alliances in China.
4 - Influenza Vaccine Supply Chain with Vaccination Promotion Effort
and its Coordination
Xinghao Yan, Assistant Professor, Ivey Business School, Western
University, 1255 Western Road, London, ON, N6G0N1, Canada,
, Gregory Zaric
We develop an influenza vaccine supply chain model consisting of a health
authority, a vaccine manufacturer, and population. The health authority decides
order quantity and effort exerted to increase vaccination demand; the
manufacturer decides production effort; and population decides the vaccination
probability. We find that the three parties’ decisions at equilibrium and different
coordinating contract formats, such as a contract with payment linear/piecewise
linear w. r. t. order quantity.
