Seminar Title: Training to mitigate the Threat of Phishing Attacks: A Mindfulness Approach



 Despite significant investments in technology to combat phishing, firms lose billions of dollars each year due to phishing attacks. Anti-phishing training using behavioral modeling has reduced vulnerability to phishing attacks; however, there is some dispute regarding training’s proper level of conceptualization. Researchers and practitioners have embraced concrete training approaches that prescribe a search for specific cues or adherence to discrete rules to avoid phishing messages. We advocate for a more abstract training approach which is focused on the mental model individuals use to evaluate suspicious messages. The abstract approach, based on the concept of mindfulness, encourages individuals to move from mindless assessments to carefully scrutinizing the actions called for by emails. To evaluate these completing training approaches, we developed two anti-phishing training programs using behavioral modeling: an abstract mindfulness program and a concrete situation-specific training program. We tested their relative effectiveness in a field study at a US university that involved 355 email users, including students, faculty and staff. To evaluate the robustness of the training, we delivered each training program in one of two formats (text-only or graphics) and used generic and customized phishing messages. Results provide support for the abstract mindfulness approach as a more effective means of training individuals to avoid phishing attacks than the concrete situation-specific approach.

Seminar Title: Crowdsourcing New Product Ideas under Consumer Learning


Crowdsourcing initiatives are becoming a popular tool for new idea generation for firms. On crowdsourced ideation initiatives, individuals contribute new product ideas and vote on other’s ideas which they would like the firm to implement. The firm then decides which ideas to implement. Although such initiatives are widely adopted in many different industries, they face increasing criticism as the number of ideas generated often decline over time, and the implementation rates (percentage of posted ideas that are implemented by the firm) are quite low raising concerns about their success.

We propose a dynamic structural model that illuminates the economic mechanisms shaping individual behavior and outcomes on such initiatives. Through counterfactuals, we identify the impact of several potential interventions on the success of such initiatives. We estimate the model using a rich dataset obtained from, which is a crowdsourced ideation initiative affiliated with Dell. We find that, on, individuals tend to significantly underestimate the costs to the firm for implementing their ideas but overestimate the potential of their ideas in the initial stages of the crowdsourcing process. Therefore, the “idea market” is initially overcrowded with ideas that are less likely to be implemented. However, individuals learn about both their abilities to come up with high potential ideas as well as the cost structure of the firm from peer voting on their ideas and the firm’s response to contributed ideas. We find that individuals learn rather quickly about their abilities to come up with high potential ideas, but the learning regarding the firm’s cost structure is quite slow. Contributors of low potential ideas eventually become inactive, while the high potential idea contributors remain active. As a result, over time, the average potential of generated ideas increases, while the number of ideas contributed decreases. Hence, the decrease in the number of ideas generated represents market efficiency through self-selection rather than its failure. Through counterfactuals, we show that providing more precise cost signals to individuals can accelerate the filtering process. Increasing the total number of ideas to respond to and improving the response speed will lead to more idea contributions. However, failure to distinguish between high and low potential ideas and between high and low ability idea generators lead to the overall potential of the ideas generated to drop significantly.

Seminar Title: Suggest or Sway? Effects of Online Recommendations on Consumers’Willingness to Pay


Recommender systems have become an integral part of the online retail environment. Prior research has focused on advancing computational approaches to improving recommendation accuracy. Only recently have their behavioral implications become an object of study. In particular, the potential impact of recommender systems on economic behavior of individual consumers represents an important issue yet to be comprehensively explored. We present the results of two controlled experiments in the context of purchasing digital songs, which explore this issue. In the first study, we found strong evidence that randomly assigned song recommendations affected participants’ willingness to pay, even when controlling for participants’ preferences and demographics. In the second study, participants viewed actual system-generated recommendations that were intentionally perturbed (introducing recommendation error) and observed similar effects on willingness to pay. The results have significant implications for the design and application of recommender systems as well as for online retail practices.

Seminar Title: Hypercompetition within Industry: Achieving and Renewing Temporary Competitive Advantages with Information Technology


In the U.S, almost all industries exhibit increasing levels of hypercompetition. Sustained competitive advantages have become very rare. Firms seek to achieve temporary competitive advantages and renew them as they are eroded by rivals. These developments challenge theories about IT-enabled sources of sustained competitive advantage. They call for new theories explaining IT-enabled sources of temporary competitive advantage. In this study, we develop a theory to explain: (1) how and why increasing IT intensity in an industry contributes to increasing levels of hypercompetition in the industry; and (2) how a firm can use IT-enabled data analytics capabilities to achieve temporary competitive advantages and renew them on an ongoing basis in a hypercompetitive industry. Drawing on complex adaptive systems theory and the economic theory of complementarities, we posit that increasing IT intensity within an industry speeds up digitization and modularization of products and business processes, establishes interconnections among previously autonomous product markets, and enhances complementarity or substitution types of mutual dependency relationships among the product markets. Via IT-enabled interconnections, strategic changes originating in one product market propagate to the complementary and substitute product markets and affect their strategic dynamics as well, and increase turbulence in performance rank orderings in an industry, a phenomenon known as hypercompetition. IT-enabled data analytics capabilities help firms to identify and manage mutual dependency relationships among product markets so that firms can achieve temporary competitive advantage in hypercompetitive industries. Agent-based simulations provide additional insights into the complex nature of IT-induced hypercompetition. They also reveal caveats of IT-enabled data analytics capabilities in taming uncertainties in a hypercompetitive industry.

Seminar Title: Cross Channel Synergies between Web and Mobile Advertising: A Randomized Field Experiment


As companies divert more funds from traditional media towards digital advertising, they are interested in understanding what effects the two channels of advertising—web advertising and mobile advertising—have on consumer choices. Any analysis that measures the effects of web and mobile advertising only separately remains incomplete. In this paper, we design and execute a randomized field experiment to estimate causal effects of cross-channel interdependence between web and mobile advertising. We conduct a consumer-level analysis to attribute cross-channel advertising to click-throughs and conversions at the individual consumer-level. This helps isolate the effect of complementarity or substitution across platforms (web and mobile) from the role of the quantity of advertising, confound with carry-over, and consumer heterogeneity. We find that a mix of online and mobile display ad acts as a better memory cue that triggers consumers to recall product and eventually click/purchase, as compared to either online ad only or mobile ad only. Hence, in channel planning, optimal decisions in one need to take account of the effects in the other. Further, we present results from policy simulations regarding the optimal level of web and mobile advertising using CPM (cost per thousand impressions) based pricing. These synergistic relationships run counter to the single-click methodology in use and suggest that, for a market in which advertising dollars are allocated based on their influence on purchase behavior, new methods must be developed to insure efficient market functioning.

September 13: Karthik Kannan to present on Economic and Policy Implications of Restricted Patch Distribution

Seminar Title: Economic and Policy Implications of Restricted Patch Distribution


In this paper, we study how restricting the availability of patches to legal users impacts vendor’s profits, market share, software maintenance decisions, and welfare outcomes. Prior work on this topic assumes that hacker’s effort is independent of the vendor’s decision to release the patch freely or not. Clearly, if the patch is not available to everyone, the hacker finds it easier to exploit the vulnerability in the product and, as a result, is likely to alter his effort. In order to understand the role of a strategic hacker, we build a game-theoretic model, where the hacker’s decision is endogenous. With this model, we find that the hacker’s effort may, on one hand, decrease the utility that the vendor can extract from the consumers. On the other hand, it may help differentiate the legal version of the product from the pirated version. A vendor can strategically exploit the hacker’s behavior in its pricing and software maintenance decisions. The endogeneity of hacker’s actions drives several of our findings that have interesting policy implications. For example, the vendor may increase the price and reduce market share in order to exploit the differentiation. In such a case, there may be more pirates in the restricted-patch case than when the patch is freely available, a result that runs counter to typical arguments provided for restricting patches. A government body that understands this trade-off may exert a different level of piracy prevention effort so that the vendor is incentivized to make decisions that improve social welfare.

Sept 6: Yili (Kevin) Hong to present on Three Essays on Global Online Labor Markets for IT Services

Seminar Title: Three Essays on Global Online Labor Markets for IT Services


I propose three essays to study the dynamics of the information systems-enabled global online labor markets for IT services. Each of these three essay deals with one of the major stakeholders of the market: the service providers, the marketplace intermediary and the employer, with each piece adding a different component on fully understanding the various dynamics of these markets.

In the first essay, I first build a game-theoretic model to understand the service provider’s equilibrium bidding behavior and employer’s winner selection to include global frictions and global labor arbitrage factors, by solving a two-stage game. The analytical analyses provide me with predictions that could be tested empirically. I then use a data set composed of a unique proprietary transaction data from Freelancer matched with five public data sources to test my theoretical predictions on provider pricing and employer selection decisions. By looking at these two aspects, I find global online labor markets are not level playing fields for service providers from countries around the world despite labor arbitrage opportunities, due to global frictions. In the second essay, I exam bidder behavior and auction performance under different auction formats – sealed bid auction versus open bid auctions. First, I derive propositions based on analytical modeling of entry and bidding behavior of service providers under different auction designs (by varying bid visibility – sealed versus open bid). I then use econometric analyses of proprietary transaction data from Freelancer that includes both open bid and sealed bid (hidden from public) to test my propositions. I find sealed bids auctions to attract more bids, albeit on average they have lower contract rate, lower quality bids and offer less buyer surplus and lower buyer satisfaction. In the third essay, I propose a quality-adjusted measure for consumer surplus to estimate the welfare online labor global markets offer to employers. I find online labor markets provide huge surplus to employers, albeit when providers’ actual quality is adjusted, the welfare estimate goes down.

The proposed three dissertation essays provide implications for understanding global frictions, auction mechanism and the societal impact of online labor markets.

May 10: Pei-yu Chen to present on Does Multi-media Advertising Pay Off? Quantifying the Value of Multi-media Advertising on Brand Purchase

Seminar Title: Does Multi-media Advertising Pay Off?  Quantifying the Value of Multi-media Advertising on Brand Purchase


Among the many decisions marketing managers must make is how to spread advertising dollars across the broad swath of available media: television, the Internet, social media, for example. With increased spending comes the need for accountability and for understanding the effectiveness of these marketing actions. Marketing practitioners, however, have been unable to efficiently measure the effectiveness of their multi- media advertising strategy in monetary terms using robust methodologies that can capture the complexity and diversity of multi-media efficacy, and thus fail to comprehensively evaluate multi-media investment with an eye toward more effective distribution of advertising dollars.

We address this industry need by quantifying the value of multi-media advertising for business. Our research interest is two-fold: Does social media affect brand purchase? If yes, how is the brand purchase generated in presence of multi-media advertising? Specifically, we draw upon the daily basis data of what households have bought, what they have watched on TV, their banner ad exposures, and what have been presented to them on their Facebook news feeds for a specific retailing product category over a 12-month observation window. We first examine whether multi-media advertising drive brand purchase, in terms of purchase counts, spending per purchase, and the total purchase value. Then we explore plausible explanations of how these brand purchases are created. We apply econometric modeling approaches, including fixed effect modeling, Fama-MacBeth cross-sectional regressions, and Seemingly Unrelated Regressions (SUR), to estimate these effects at disaggregate level, yet controlling for advertising endogeniety and heterogeneity.

We find that multi-media advertising effect exist and is important, while the relative effectiveness vary across media. Much of the impact of multi-media advertising can be attributed to the focal company’s market expansion, promotion on future purchase, and advertising externalities from competing brands. This study adds to our empirical knowledge of how different media channels work in concert – yet differing in their relative effectiveness – to drive marketing effectiveness. The findings point to how managers could gauge the potential value of seeding additional advertising channel and optimize the marketing mix to generate brand purchase.

Seminar Title: Digital Natives and Ubiquitous Information Systems


Most IS research until now has focused on information systems in organizations and their use by digital immigrants. Digital immigrants are those who were not born into the digital world – they learnt to use information systems at some stage in their adult life. An underlying assumption of much of this research is that users “resist” technology or at least have some difficulty in accepting it. Digital natives, however, are those who have grown up in a world where the use of information and communications technology is pervasive and ubiquitous. These ubiquitous technologies, networks and associated systems have proliferated and have woven themselves into the very fabric of everyday life. We suggest that the rise of the digital native, along with the growth of Ubiquitous Information Systems (UIS), potentially represents a fundamental shift in our “paradigm” for IS research. We propose a research agenda that focuses on digital natives and UIS. This seminar is based on and updates a paper recently published in Information Systems Research.
