ABSTRACT
While consumers adoption of new technology has received substantial
interest from researchers, the mechanism of consumers post-adoption
evaluation derived from continued use of m-services and its impact on
their interest in upcoming m-services are yet to be explored. Drawing
on the appraisal → emotional response → coping framework,
this study investigates 1) how utilitarian and hedonic values derived
from consumers basic and innovative benefits of m-services influence
their post-adoption satisfaction with current m-services and 2) the
impact of post-adoption satisfaction on interest in future m-services
in the context of young consumers mobile phone use. The results
support all the hypothesized relationships except for the relationship
between innovative benefit and utilitarian value. Theoretical and
marketing implications are provided.
Keywords: M-services, benefit, value, satisfaction, interest in future

Disarming the Bid Sniper

ABSTRACT
Bid sniping is the most common strategy used in online auctions
whereby the bidder places a bid in the closing seconds in order to win
the auction. This denies other bidders the time to react and
suppresses the final price. While bid sniping is beneficial to the
winner, it disadvantages other bidders and the seller does not get the
full amount of revenue s/he might otherwise have received in a truly
competitive and fair auction. This paper proposes a method to help
negate bid sniping as a dominant strategy for winning in online
auctions. We propose an amendment to the auction format that allows
for a random undisclosed time-out extension should new bids be
received in the closing moments. This entices bidders to bid their
true valuation up front, otherwise they risk having the auction
terminate and therefore not accept any new bids. Several variations
of the amended auction format are presented that effectively
counteract bid snipers by making it difficult to gain any information
by observing the underlying algorithm. To ensure the auction does not
continue indefinitely, the format includes mechanisms that place
random bounds on the size of, and number of extensions permitted. Our
proposal also makes intelligent decisions to maximize the price for
the seller based on the auctions bid volume. The size of the
extension granted is based on the timing and aggressiveness of how
bids are being submitted. To our knowledge, no existing online
auctioneers offer such a comprehensive format for actively
discouraging bid sniping.

Revenue?

ABSTRACT
Social media has become an important avenue of Word-of-mouth (WOM) and
a recent study has found blogging to be an important lead-generation
source among social media options. This article examines the dynamic
interrelationship between word-of-blog volume and sales by using the
movie industry as the research context. By employing the Granger
Causality test and modeling the interrelationship through simultaneous
equations, the results show that the volume of word-of-blog and box
office revenue for movies provide significant causality and
explanatory power for each other, supporting word-of-blog volume is
both a predictor and an outcome of sales. The results also highlight
for retailers the importance of strategically managing word-of-blog to
influence consumer purchase decisions and generate revenue as well as
the value of the findings for forecasting.

Distribution: The Case of Spanish Electronic Commerce

ABSTRACT
Not all countries have the same level of e-commerce penetration. This
could be due to the influence of cultural factors on consumer trust
with regard to online purchasing. This may also explain why countries
like Spain, with similar economic and technological levels to its
neighbours, have a lower level of e-commerce usage. This paper
examines the antecedents of trust, and, the relationship between trust
and consumer commitment in Spain. The results obtained show that the
factors governing the development of online trust are similar to those
detected in other countries. Specifically, the results show that
consumer trust is influenced by perceived website usability and
reputation, by the consumer satisfaction and by the perceived privacy
and security policy of the website. This paper also verifies that
consumer trust has a positive effect on consumer commitment. Besides,
no significant differences are observed in the research model between
online services and product distribution. Finally, managerial
recommendations and future research lines are suggested.
Keywords: Trust, Culture, Commitment.

Personalized Recommender System Using Entropy Based Collaborative
Filtering Technique

ABSTRACT
This paper introduces a novel collaborative filtering recommender
system for ecommerce which copes reasonably well with the ratings
sparsity issue through the use of the notion of selective
predictability and the use of the information theoretic measure known
as entropy to estimate the same. It exploits the predictable
portion(s) of apparently complex relationships between users when
picking out mentors for an active user. The potential of the proposed
approach in providing novel as well as good quality recommendations
have been demonstrated through comparative experiments on popular
datasets such as MovieLens and Jester. The approachs additional
capability to come up with explanations for its recommendations will
enhance the users comfort level in accepting the personalized
recommendations.
Keywords: Recommender System, Collaborative Filtering,
Personalization, Entropy, Ecommerce
