1 - New Business Models for Green Technology Adoption in Split
Property Rights and Rents Situations
Anton Ovchinnikov, Queen’s University, 143 Union St. West,
Kingston, Canada,
In many situations, the owner of the asset that is being improved with green
technology is not one that enjoys the benefits from the improvement. For
example, the landlord may incur the costs of energy-efficiency upgrades, while
the tenant will enjoy the savings in energy costs. Such split in property rights and
rents is a major deterrent in the adoption of green technologies. I will discuss two
case studies highlighting the industry practice and issues, and opportunities to
resolve them.
2 - The Impact of Extended Producer Responsibility on Selling and
Leasing Strategies
Ni Fang, HEC Paris, 1, Rue de la Liberation, HEC Paris, Jouy en
Josas, DI, 78351, France, , Andrea Masini
While product take-back legislation based on the Extended Producer
Responsibility (EPR) concept is becoming an increasingly popular instrument to
reduce waste, its actual operational and environmental impact remains unclear.
This paper examines how EPR legislation affects the optimal channel allocation
decisions of a firm that either sells, leases, or concurrently sells and leases durable
products, and it discusses the competitive and environmental implications of
regulation.
3 - The Buyer’s Role in Improving Energy Efficiency in Supply Chains

, Karen Donohue, Mili Mehrotra
We investigate the equipment-focused EE investment decision in the context of a
supply chain where a capital constrained manufacturer sets the investment level
and its buyer sets contract prices. We investigate the impact of different factors
including policy incentives and global competition on the investment decisions.

1 - What if Hotelling’s Firms Can Deliver Their Products?
Competitive and Social Implications
Alireza Yazdani, University of Oregon, 2250 Patterson St.,
Unit 220, Eugene, OR, 97405, United States of America,
, Eren Cil, Michael Pangburn
We study the competition between two firms serving dispersed customers, which
we model using Hoteling’s classic linear city model. In the classic framework,
travel costs are borne by consumers, but potentially firms could absorb those costs
by making deliveries to customers. We explore the competitive and social
implications of these two alternatives for serving customers demands, considering
both product design and pricing decisions.
2 - Dynamic Pricing of Multiple Substitutable Products with Search
Cost and Local Behavioral Influences

We consider a seller offering n types of substitutable products over T time periods.
Customers incur a search cost for inspecting the products, and may examine only
a subset of the products. They are also assumed to have a local behavior in the
search process. Given inventory state and time, the firm aims to find the optimal
price of the products maximizing its profit.
3 - Social Loafing and Queue Driven Speedup: Evidence
from a Supermarket
Yong-Pin Zhou, Associate Professor of Operations Management,
University of Washington, Seattle, WA, 98195-3226,
United States of America, , Jingqi Wang
We study factors affecting cashiers’ service rate using data from a supermarket.
We find that customer waiting pushes cashiers to work faster. We also observe
that pooling has a negative impact on cashiers’ service rate.
4 - Physician Dual Practice; When Revenue is Not the Only Thing
that Matters
Vasiliki Kostami, London Business School, London Business
School (MSO dept), Regent’s Park, London, NW1 4SA,
United Kingdom, , Dimitrios Andritsos
Physician dual practice refers to the simultaneous practice of medicine by
physicians in both public and private settings. In the presence of dual-practice, we
are looking at the optimal proportion of time that physicians may be willing to
invest in a private practice. How does that proportion depend on the physicians
objective? And how does this affect the severity of the patients that are treated in
the public versus the private clinics?

1 - Assortment Planning Decisions in a Two-sided Market
Ying Cao, University of Texas at Dallas, 800 W. Campbell Rd,
Richardson, TX, 75080, United States of America,
Dorothee Honhon, Sridhar Seshadri
We consider the problem of a firm optimizing its assortment when facing a two-
sided market. The firm receives revenues from customers purchasing the products
as well as from advertising company who offer to pay various amounts for
reaching customers from different segments. We explore structural properties of
the optimal assortment and compare it to the solutions of the one-sided market
problems.
2 - Managing Online Content to Build a Follower Base:
Model and Applications
Felipe Caro, University of California Los Angeles,
110 Westwood Plaza, Box 951481, Los Angeles, CA, 90095-1481,
United States of America,
Victor Martínez-de-Albéniz
Content providers typically manage a dual objective of generating interest for
current content and at the same time reaching out to new audiences that may
become repeat users. The pace at which content is created must thus take into
account how much current content contributes to the follower base. We develop
a simple model to study base build-up dynamics, and use it to optimize the total
traffic received by the content provider through stochastic dynamic programming.
3 - Choosing an Assortment Rotation Strategy to Boost Sales
Kris Johnson Ferreira, Harvard Business School, Morgan Hall
492, Boston, MA, 02163, United States of America,
David Simchi-levi
Assortment rotation strategies vary widely across fashion retailers; the flash sales
industry uses a frequent assortment rotation strategy, introducing new products
every day. We build a finite-horizon stochastic dynamic programming model to
better understand the consumer’s purchase decisions under this strategy. We
analyze and compare our model to the setting where all products are offered for
the entire selling season and explore under what conditions the retailer should
employ each strategy.
4 - Estimating and Optimizing the Impact of Inventory on Consumer
Choices in Fashion Retail
Victor Martínez-de-Albéniz, Associate Professor, IESE Business
School, Av. Pearson 21, Barcelona, 08034, Spain,
, Pol Boada
We empirically study the impact of inventory (as opposed to availability) on sales.
We develop a market share model where we show that product-level inventory
has a large impact on its market share within the category. This supports the idea
that inventory plays a major role in helping customers choose a particular product
within the assortment. We finally describe how a retailer should optimally decide
its inventory levels within a category.
