1 - Methodology for Codifying Qualitative Twitter Content into<br />
Categorical Data<br />

Twitter provides an immense wealth <strong>of</strong> qualitative data both in aggregate and at the<br />
individual account level. This paper proposes a method <strong>of</strong> classification <strong>of</strong> individual<br />
Twitter account content across a two level multiple domain framework. Whilst a<br />
range <strong>of</strong> prior studies have emphasized the quantification and classification <strong>of</strong> the<br />
Twitter public timeline, this method is purpose designed to operate within the<br />
account specific level for the purposes <strong>of</strong> benchmarking, analysis and classifying the<br />
use <strong>of</strong> Twitter at the individual level. This paper expands the existing application <strong>of</strong><br />
Twitter as a data source for understanding marketing communications performance in<br />
social media by <strong>of</strong>fering a split level classification scheme that can codify performance<br />
<strong>of</strong> an account holder in the primary domains <strong>of</strong> conversation, status reporting,<br />
information relay, news creation, and phatic communications. The method allows for<br />
a richer classification schema by expanding the five categories with further<br />
refinement to explore how the account is used for interaction in the social media<br />
space. The novelty <strong>of</strong> the method is the focal point <strong>of</strong> providing data to assess the<br />
performance <strong>of</strong> an account against the account author’s intended use <strong>of</strong> the service.<br />
The paper concludes with recommendations for the use <strong>of</strong> the methodology for<br />
market segmentation, social media communication objective setting, and as a rich<br />
social media metric.<br />

Companies are increasingly confronted with new challenges in the era <strong>of</strong> Web 2.0. In<br />
this study, we focus on the role <strong>of</strong> brand equity (i.e., strong brand vs. weak brand) in<br />
an environment characterized by the proliferation <strong>of</strong> social media and the interactive<br />
interface between consumers and brands. Two powerful features <strong>of</strong> this environment<br />
are transparency and criticism (Fournier and Avery 2011). Once a crisis happens (e.g.,<br />
product-harm recall), negative buzz is typically generated not only in traditional<br />
media but also in social media. It is difficult for a company to bury the mistake, and<br />
even worse, the social media environment makes consumers more critical <strong>of</strong> the<br />
company and its brand after a crisis. Conventional branding wisdom suggests strong<br />
brands can increase the firm’s pr<strong>of</strong>its and reduce the vulnerability <strong>of</strong> cash flows. Yet<br />
in the current environment, the bigger the brand the more vulnerable it is. Our<br />
objectives are to examine whether a strong brand alleviates the negative impact <strong>of</strong> a<br />
crisis event and to assess how the different metrics <strong>of</strong> social media moderate the<br />
impact <strong>of</strong> brand equity on the components <strong>of</strong> shareholder value: the levels <strong>of</strong><br />
abnormal returns and stock risks. Using the event study method, we examine product<br />
recall announcements during a three-year period from 2008 to 2010 and incorporate<br />
daily user-generated content metrics such as volume and valence within the event<br />
window. We conclude with a discussion that the role <strong>of</strong> brand in Web 2.0 in risk<br />

Trendspotting has been an important marketing intelligence tool for identifying and<br />
tracking major movements in consumer interest and behavior. Currently,<br />
trendspotting is done either qualitatively by “trend hunters” who comb through<br />
everyday life in search <strong>of</strong> signs indicating new trends in consumer needs and wants,<br />
or quantitatively by analysts who monitor individual indicators, such as how many<br />
times a keyword has been searched, blogged or “twitted” online. In this study, we<br />
demonstrate how the latter can be improved by uncovering common temporal<br />
patterns hidden behind the co-evolution <strong>of</strong> a large array <strong>of</strong> indicators. We propose a<br />
structural dynamic factor-analytic model that can be applied for simultaneously<br />
analyzing tens or even hundreds <strong>of</strong> time series, distilling them into a few latent<br />
dynamic factors that isolate seasonal cyclic movements from non-seasonal nonstationary<br />
trend lines. We demonstrate this novel multivariate approach to<br />
quantitative trendspotting in one application involving a promising new source <strong>of</strong><br />
marketing intelligence – online keyword search data from Google Insights for Search,<br />
wherein search volume patterns across 38 major makes <strong>of</strong> light vehicles were<br />
analyzed over a 81-month period to identify key latent trends in consumer vehicle<br />
shopping interest.<br />
4 - Is All That Twitters Gold? Market Value <strong>of</strong> Digital Conversations in<br />
Social Media<br />

Social media are growing to be highly influential. Consumers and marketers are<br />
increasingly adopting social media such as Facebook, Twitter, YouTube. Even the<br />
president <strong>of</strong> the United States <strong>of</strong> America has a Twitter account. Some studies have<br />
shown that Tweets forecast movie revenues (Asur and Huberman 2010; Rui et al.<br />
MARKETING SCIENCE CONFERENCE – 2011 SA03<br />
71<br />
2010). However, research has not investigated the relationship between Tweets about<br />
brands and the stock market value <strong>of</strong> firms that own those brands. The authors<br />
collect more than 9 million tweets from Twitter for eight brands to address this issue.<br />
The authors use text mining techniques to create measures <strong>of</strong> volume, valence and<br />
word <strong>of</strong> mouth from the Twitter data. Using data at a daily level for a period <strong>of</strong> 6<br />
months from October 2009, they evaluate whether the Twitter metrics have an<br />
impact on the stock market performance <strong>of</strong> firms using Vector AutoRegressive<br />
models. They control for several exogenous variables such as analyst coverage,<br />
advertising expenditures and key firm developments such as innovations, mergers,<br />
announcement <strong>of</strong> earnings, client contracts, strategic alliances, lawsuits and changes<br />
in key executives. The authors find that digital conversations in social media have a<br />
relation with stock market performance measures (7 <strong>of</strong> 8 brands have effects on<br />
abnormal returns). However, most <strong>of</strong> the effects are short term supporting the notion<br />
<strong>of</strong> market efficiency. Retweets (word <strong>of</strong> mouth) is the metric <strong>of</strong> Twitter with the most<br />
influence on abnormal returns. Volume <strong>of</strong> tweets is the metric with the most<br />
influence on trading volume. The authors discuss managerial implications <strong>of</strong> these<br />
results.<br />

1 - Disentangling the Effects <strong>of</strong> Online Shopping Decision Time on<br />
Website Conversion<br />

Research on total time spent on pre-purchase information search on retail websites<br />
has shown contradictory effects on consumer purchase behavior. While some<br />
research has emphasized the positive effects <strong>of</strong> decision time online on conversion<br />
due to the fact that it increases the probability that the consumer selects an attractive<br />
product as well as decreases choice uncertainty, other studies showed that decision<br />
time represents higher consumer effort and an increased opportunity cost and, hence,<br />
has a negative effect on conversion. In order to explain these conflicting findings, we<br />
disentangle total decision time spent on a retail website into product comparison and<br />
product inspection time. We hypothesize that these two aspects have opposing effects<br />
on website conversion. First, we expect that spending more time comparing<br />
alternatives decreases the chances <strong>of</strong> conversion. The underlying reason is that<br />
comparison time is an indication <strong>of</strong> the difficulty <strong>of</strong> the choice set and <strong>of</strong> choice<br />
uncertainty which increases the risk associated with making a decision. Second, we<br />
expect that spending time inspecting each given alternative increases the chance <strong>of</strong><br />
conversion, because it represents a higher expected utility <strong>of</strong> searching for<br />
information on the alternative. Using clickstream data from 16600 consumers that<br />
visited a mortgage recommendations website, we find support for the proposed<br />
relationships. This underlines the theoretical importance <strong>of</strong> disentangling total<br />
decision time. Online firms can also benefit from our findings to improve the<br />
composition <strong>of</strong> the <strong>of</strong>fered product choice sets by taking into consideration the<br />
allocation <strong>of</strong> time spent by consumers on a given session and by balancing<br />
consumers’ time comparing alternatives with time spent inspecting alternatives’<br />
details.<br />

This study seeks to examine how different types <strong>of</strong> information – product-related and<br />
price-related information provided by retailers – impact purchase-related outcomes<br />
for consumers belonging to different states <strong>of</strong> shopping. Using mixture-modeling<br />
techniques on clickstream data obtained from a large online durable goods retailer,<br />
we find that a three-state model comprised <strong>of</strong> directed shoppers, deliberating<br />
researchers and browsers, best describes the latent differences across customers. In<br />
examining the impacts <strong>of</strong> information on purchase outcomes, we find that product<br />
and price-related information impacts consumers in these three shopping states<br />
differently. While product information highlighting features <strong>of</strong> product alternatives in<br />
a category has the strongest impact on deliberating researchers, specific price<br />
information related to category-level discounts increases the likelihood <strong>of</strong> purchase<br />
for both directed shoppers as well as browsers. Price information relating to site-wide<br />
free shipping has a positive impact on purchase for all consumers. Surprisingly,<br />
category-level discounts have a negative impact on deliberating researchers, while<br />
rich product information hampers the purchase process <strong>of</strong> directed shoppers. We<br />
discuss the managerial implications <strong>of</strong> our findings and the role <strong>of</strong> clickstream<br />
analytics in designing dynamic targeting and information provisioning strategies for<br />
online retailers.
