1 - On the Robust Design of Access Networks Integrating Optical
Fiber and Wireless Technologies
Fabio D’Andreagiovanni, Senior Researcher, Konrad-Zuse-
Zentrum för Informationstechnik, Takustr. 7, Berlin, Germany,
, Jonad Pulaj, Axel Werner
An important recent trend in telecommunication access networks is the
integration of optical fiber and wireless technologies (Fi-Wi). The design of Fi-Wi
networks can be formulated as variants of Connected Facility Location Problems,
including fiber connectivity and wireless coverage constraints. We consider here
an uncertain version of the Fi-Wi design problem, tackling signal propagation
uncertainty. We introduce a new model for it and present computational results
on realistic instances.
2 - Two Terminal Reliability in a Mobile Ad-hoc Network

The spatial distribution of nodes in a random waypoint model of a Mobile Ad-hoc
communications networks exhibits central tendency. In this presentation, we will
discuss analytical expressions for one and two hop connectivity as a function of
node location.
3 - Impact of Security Concerns on Online Shopping by Device

As various devices are used to access online stores, it is unclear if consumers’
security concerns impact shopping decisions equivalently regardless of access
device. In this study we characterize the impact of security concerns across device
types and show that consumers with security concerns are far less likely to make
purchases using a mobile device than a personal computer. Similarly, we show
that individuals without security concerns are the major drivers behind mobile
commerce.

Managing Innovation: Products, Services, Employee
Attributes and Organizational Performance

1 - The Relationship Between Individual Employee Attributes and
Radical Innovation
Lee Davis, Associate Professor, Copenhagen Business School,
Department of Innov and Org Econ, Kilevej 14A, Frederiksberg,
2000, Denmark, Karin Hoisl, Jerome Davis
We investigate the impact of individual employee attributes like experience,
ability or motivation on radical innovation and whether the organizational
context moderates this relationship. We find that the importance of individual
attributes varies with organizational context.
2 - The Impact of Organizational Routines in Cumulative Innovation

The capacity to continuously innovate is crucial for organizations to achieve or
maintain their competitive advantage. A sequence of innovations can provide to a
company not just a new product or technique but also a platform of knowledge
that will support their future innovations. This work investigates the way
knowledge is accumulated by a company over time, associating managerial
decisions to the dynamics of innovation.
3 - Product and Service Modularity Strategies Game for
Mass Customization

Modularity has been recognized as a powerful concept for improving the
efficiency and management of product design and manufacturing. However, the
integrated view on product and service modularity approaches is under
researched. We propose four strategies to match combinations of products and
services through modularization strategies for mass customization.
4 - The Impact of Product and Service Modularity on Business
Performance – A Survey of Danish Manufacturers
Thomas Frandsen, Copenhagen Business School, Dept. of
Operations Management, Solbjerg Plads 3, Frederiksberg, DK-
2000, Denmark, , Juliana Hsuan, Jawwad Z. Raja
Manufacturers are increasingly turning towards services and integrated solutions
as a way of strengthening their competitiveness, a transition receiving growing
attention in the literature. However, the relation between product and service
architecture and its impact on service strategy and the performance of
manufacturers is not well understood. Based on a survey of Danish
manufacturers we explore the relationship between product and service
modularity and their effects on business performance.

1 - Competition Among Proprietary and Open-source Software Firms:
The Role of Licensing

Open-source software (OSS) firms are increasingly using service-based business
models to compete with established proprietary software firms. We study a 3-way
game with strategic contribution from the community and focus on how open-
source licensing affects competition among an open-source originator,
open-source contributor, and a proprietor competing in the same software
market.
2 - An Empirical Study of Market Switching Behavior of
Mobile App Developers
Hossein Ghasemkhani, Assistant Professor, Purdue University,
425 W. State Street, West Lafayette, IN, 47907, United States of
America, Young-Jin Lee, Karen Xie,
Yong Tan
Mobile app developers switch the positioning of their apps between free and paid
submarkets. They offer their previously paid apps for free to create positive
network effects, and set prices on previously free apps to reap the benefits. We
empirically study the developers’ decision to determine the instantaneous market
of their apps, and examine how it affects performance. We find that prior
performance and duration in either market are significantly related to the
developer’s decision.
3 - How Does Communication Improve Conversion Rate on
E-commerce: A Bayesian Approach
Haoyan Sun, PhD Candidate, University of Washington,
Mackenzie 328, Seattle, WA, 98115, United States of America,
, Ming Fan
We examine communication of buyers and sellers on the E-commerce platform
through Instant Message (IM) to understand the ways of improving conversion
rate. By casting this problem in a hierarchical bayesian framework, we are able to
address the endogeneity problem where IM communication is endogenous in
determining the conversion rate. Using data collected from TaoBao, China’s
leading C2C online marketplace, we show that communication can significantly
drive the conversion rate.
