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 auction’s 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.

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.

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 approach’s additional
capability to come up with explanations for its recommendations will
enhance the user’s comfort level in accepting the personalized
recommendations.

Keywords: Recommender System, Collaborative Filtering,
Personalization, Entropy, Ecommerce
