2 - Optimal Dynamic Product Development And Launch For A

Network Of Customers

Nur Sunar, UNC,

John Birge, Sinit Vitavasiri

We consider a firm that dynamically chooses its effort to develop a product for a

network of customers represented by a general connected graph. In addition to

dynamically choosing its development effort, the firm chooses when to launch or

abandon the product. If the firm launches the product, the firm also chooses a

selling price, a promotional price and a target customer to offer promotion. Once

the target customer adopts the product, the product dynamically diffuses over the

customer network based on the topology of the graph and the selling price. In a

continuous-time setting, we explicitly solve the firm’s jointly-optimal

development, launch and post-launch strategies for any connected network.

3 - Quantity Pre-commitment And Cournot Equivalence

We study a two-stage oligopolistic competition game, called the Quantity Pre-

Commitment game, in which firms compete on quantity in the first stage and

then compete on price in the second stage. This game is compared to a single-

stage Cournot game, in which firms compete on the quantity only and the prices

are set to clear the market. We show an equivalence result that an equilibrium of

the Quantity Pre-Commitment game coincides with an equilibrium of the

Cournot game, under certain conditions. The conditions that we identify are more

general than those of specific models used in the seminal papers in the literature.

4 - A Stochastic Model For Pricing In Reverse Supply Chains

We address channel coordination issues in a two-echelon reverse supply chain

that consists of a collector and a manufacturer. We develop stochastic models to

maximize the manufacturer’s and collector’s profits in a game-theoretic

framework. We develop an effective mechanism to coordinate manufacturer’s and

collector’s decisions.

1 - A Data-driven Approach To Customer Segmentation

We propose a new “model-based” projection technique for segmenting customers

based on partial observations for each customer. We suppose that data are

available in the form of categorial responses for on a collection of n variables for

each customer. This unified representation allows one to combine diverse signals

(clicks, demographics, purchases, etc.) to obtain accurate segmentation. Our

method relies on a combination of model-based projections and matrix

completion techniques to obtain the clusters. We theoretically and empirically

show how our method is superior to existing benchmarks.

2 - Analysis Of Choice Models: A Welfare-based Framework

Xiaobo Li, University of Minnesota, Minneapolis, MN, 55414,

We propose a framework for discrete choice models through a welfare function.

The framework provides a new way of constructing choice models. It also

provides great analysis convenience for establishing connections among existing

choice models. We define a new property in choice models:

substitutability/complementarity and study conditions for a choice model to be

substitutable. We show that our framework is flexible in this property, which is

desirable in capturing practical choice patterns.

3 - A Dynamic Clustering Approach To Data-driven Assortment

Personalization

Fernando Bernstein, Duke University,

Sajad Modaresi, Denis R. Saure

A retailer faces heterogeneous customers with initially unknown preferences. The

retailer can personalize assortment offerings based on available profile

information; however, users with different profiles may have similar preferences,

suggesting that the retailer can benefit from pooling information among

customers with similar preferences. We propose a dynamic clustering approach

that adaptively adjusts customer segments and personalizes the assortment

offerings to maximize cumulative profit.

4 - Assortment Rotation And The Value Of Concealment

Kris Johnson Ferreira, Harvard Business School,

kferreira@hbs.edu,

Joel Goh

The frequency at which retailers change their assortment varies widely across

fashion retailers. Some retailers choose to sell products simultaneously

throughout the season, whereas others choose to sell products sequentially,

requiring that the consumer make a purchase decision before seeing the

subsequent products for sale. By offering products sequentially, retailers can

introduce uncertainty in consumer choice that affects purchase decisions. We

develop a consumer choice model and finite-horizon stochastic dynamic program

to study when this uncertainty is advantageous for a retailer: a phenomenon we

refer to as the retailer’s value of concealment.

1 - User Reward Programs In Online Social Media

Online social media (OSMs) have become a popular and growing Internet

phenomenon, as exemplified by the millions of followers of websites like

YouTube, Twitter, and Facebook. Given the Internet’s ease of access and the high

degree of competition to attract users to these sites, a question arises as to

whether OSMs should develop revenue-sharing programs as a way to reward

their contributing users. We present an ex ante asymmetric duopoly OSM game,

where heterogeneous users are either active or passive with respect to each OSM.

In this study, we explore how online users’ actions and perspectives impact the

outcome of the competition among OSMs.

2 - Research On The Influence Of Microblog Advertising Of Theatre

Chain On Its First Week Box Office Revenue

With the participation of enterprise in social network, a question arises of how

enterprise can gain more real profit from social network advertising. This article

analyzes the relationships among contents of enterprise’s online post, consumer’s

participation on microblog, and short-term product sales. Taking movie market as

research set, this research finds that short-term product sales is positively

influenced by the information quantity of enterprise’s post, and the influence is

mediated by the “repost” of other users of Sina microblog. The mechanism

examined in this research on the influence of microblog advertising on short-term

sales can be guidelines of social network advertising.

3 - Social Media Use And New Product Development Performance

Use of social media is becoming increasingly popular in new product development

(NPD). Yet, the performance impact of social media use in NPD remains

inconclusive. Using a cross industry survey of new product development projects,

we explore the factors affecting the relationship between social media use and

NPD performance.
