Revenue Management and Pricing in Practice<br />

1 - Randomized Linear Programming Approach to Revenue<br />
Management<br />

We provide a high-level overview of our approach to RM using RLP. Following<br />
are the key features of our methodology: a) Pricing of price-dependent products.<br />
b) Handles network-level overbooking as opposed to resource-level overbooking<br />
typically found in practice. c) Allows for imposition of service level constraints. d)<br />
Computes ancillary outputs such as occupancy forecast, revenue forecast and<br />
service levels, which are useful metrics for a revenue manager.<br />
2 - Dynamic Pricing and Revenue Management<br />
Maarten Oosten, SAS Institute, World Headquarters,<br />

New technologies allow for pricies to be changed continuously, and optimal<br />
dynamic pricing algorithms take this freedom explicitly into account. In this<br />
presentation we explore several directions in which this can be taken.<br />
3 - Estimation of Nested Logit Models using Data from a Single<br />
Firm<br />

We examine identification issues for estimating parameters for discrete choice<br />
models with censored data. Most work in revenue management using such<br />
models has been focused on simple multinomial logit models, because the unique<br />
IIA property of this model makes estimating and applying parameters convenient.<br />
However, IIA is not usually consistent with actual choice behaviors. We examine<br />
the benefits and drawbacks of employing a nested logit model, which does not<br />
exhibit IIA.<br />
4 - Improving the Forecasting Accuracy of Hotel Arrivals:<br />
A New Non-homogeneous Poisson Approach<br />
Misuk Lee, IHG, 3 Ravinia Drive, Atlanta, GA, 30327,<br />
United States of America, Misuk.Lee@ihg.com<br />
Demand forecast is one of key components of hotel revenue management. This<br />
study develops a new non-homogenous Poisson process approach to short-term<br />
demand forecast. By considering seasonality and heterogeneous booking curve<br />
patterns, we find better estimates for demand processes and thus improve<br />
forecasting accuracy. We present validation results on IHG hotel data along with a<br />
comparison to other benchmark models.<br />

Impact of Customer Behavior on Service<br />

1 - How Do Customers Respond to Service Quality Competition?<br />
Ryan Buell, Assistant Professor, Harvard Business School,<br />
Morgan Hall T37, Boston, MA, 02163, United States of America,<br />
rbuell@hbs.edu, Dennis Campbell, Frances Frei<br />
When does increased service quality competition lead to customer defection, and<br />
which customers are most likely to defect? We find that customers defect at a<br />
higher rate from the incumbent following increased service quality (price)<br />
competition when the incumbent offers high (low) quality service relative to<br />
existing competitors in a local market. We further show that it is the high quality<br />
incumbent’s most profitable customers who are the most attracted by superior<br />
quality entrants.<br />

2 - Modeling Customer Behavior in Multichannel Customer<br />
Support Services: An Information Stock Approach<br />
Serguei Netessine, Professor, INSEAD, Boulevard de Constance,<br />

Kinshuk Jerath, Anuj Kumar<br />
We analyze multichannel customer support environment of a health insurance<br />
firm in the US. We build a structural probability model to understand the<br />
customers’ query arrival and channel choice processes. Our estimates suggest the<br />
telephone channel in our setting on average provides 20 times more information<br />
than the Web channel and that the Web on average provides information need<br />
instead of information gain – Web in our setting seems to confuse customers.<br />
3 - Customer Response to Short-Term Price Fluctuations<br />
Margaret Pierson, Assistant Professor, Tuck at Dartmouth,<br />
Hanover, NH, United States of America, mpierson@hbs.edu<br />
Transactions at 15 gasoline stations in Massachusetts over two years are used to<br />
estimate consumer elasticity with respect to price on a transaction basis. A<br />
significant proportion of the observed transactions display high sensitivity to<br />
price. This customer behavior results in congestion at pumps during high prices, a<br />
counterintuitive result which constrains stations’ price choices in practice.<br />

Service Scripting and Value Co-Creation<br />

Using the insights of the research on scripting and organizational improvisation,<br />
we develop an econometric model of the impact of different degrees of scripting<br />
and improvisation on services financial outcomes. We test our model using survey<br />
data and self reported financial performance from the hospitality industry.<br />
2 - Co-Creation of Value for IT-Enabled Services:<br />
A Case of Geocaching<br />

tuure@tuunanen.fi, Tero Vartiainen<br />
This study uses laddering interviews to explore how value is co-created for ITenabled<br />
services, more precisely geocaching. The results reveal that geocaching is<br />
distinctly hedonic in nature. The results also demonstrate how the consumer<br />
information systems framework can be applied for understanding which factors<br />
influence value co-creation for IT-enabled services.<br />
3 - Analysis of Role of Service Variety and Real Options in Resort<br />
Timeshare Service Value<br />
Gregory Heim, Associate Professor, Mays Business School at Texas<br />

gheim@mays.tamu.edu<br />
Although a major class of hospitality/travel experience service, little empirical<br />
research has examined timeshares or other fractional hospitality services. This<br />
paper examines whether service variety, in terms of breadth of vacation service<br />
experiences, or real options more strongly affect the perceived quality, valuation,<br />
and ownership of resort hotel timeshare services. We analyze hypotheses using<br />
both cross-sectional and longitudinal data sets.
