Emergent Phenomena and Process Dynamics: The Next Frontier for Team Research

Emergence has received relatively limited direct research attention in the micro and meso disciplines of organizational science (i.e., organizational psychology, organizational behavior, and human resource management). It has largely been treated as latent and assumed, assessed within a limited conceptualization, and examined in a static fashion. This is part of a broader problem in organizational psychology and behavior research (OP/B) that treats team (and other) processes as static constructs. I will discuss emergence as a multilevel process and focus on its point of origin, interaction patterns, and the dynamics of how phenomena emerge. I will discuss how emergent phenomena are typically studied in organizational science and the limitations inherent in the dominant approaches. Once emerged, team processes also exhibit dynamics with respect to the stability of the emerged phenomenon, the form of emergence, and variability in its level. Given these conceptual complexities, investigating emergence is challenging and necessitates new methodologies. I will discuss innovations in research design and measurement that are required to advance understanding of emergence as a process and team processes as dynamic phenomena. I will present some novel approaches and will illustrate them by highlighting my current research.

Corn or Soybean: Dynamic Farmland Allocation under Uncertainty

Operations Management & Information Technology

Speaker: Onur BOYABATLI
Assistant Professor , Singapore Management University

This paper studies the farmland allocation decision of a farmer between two crops in a multi-period framework. In each growing period, the farmer chooses the allocation in the presence of revenue uncertainty, and crop rotation benefits across periods, i.e. revenue is stochastically larger when a crop is planted in a rotated land (where the other crop was planted in the previous period). We identify two strategies, monoculture, i.e. fully allocate the farmland to one of the crops, and rotate, i.e. plant each crop in the rotated farmland, which characterize the optimal allocation decision in each period. Our analysis provides rules of thumb for the impact of revenue uncertainty: The farmer benefits from a lower revenue correlation between the two crops. Interestingly, the farmer benefits from a higher revenue volatility only when this volatility is sufficiently high; otherwise, a lower revenue volatility increases the profitability. We propose a heuristic allocation policy which we characterize in closed form. Using a calibration based on a representative farmer planting corn and soybean in Iowa, we show that the proposed policy is near-optimal, and significantly outperforms the commonly used heuristic allocation policies in practice (such as the myopic policy, always-rotate policy and monoculture policy).

"How Bad Is Shopping Cart Abandonment? An Investigation across Multiple Shopping Sessions"

Abstract:

Shopping cart abandonment is considered the bane of Internet retailing and has received increasing attention in the retail industry. Most shopping cart abandonment metrics used in practice are based on purchase outcomes within a given web navigation session and ignore the fact that online consumers can and often do break up a given shopping task into multiple shopping sessions. In this study, we investigate online cart abandonment across multiple shopping sessions and examine its connections to consumers’ order and purchase spending decisions. We propose a joint model of cart, order, and spending decisions that takes into account their interdependencies within and across shopping sessions, and provide a method for accurately predicting the eventual shopping cart abandonment rate. We illustrate the application of our proposed methodology using data provided by an online grocery retailer and examine the effectiveness of shopping cart recovery promotions under different scenarios through simulation analyses.

Our study shows that consumers often break a shopping task into multiple shopping sessions, and that the eventual shopping cart abandonment rate is much lower when this is taken into consideration. We find strong interdependences between the cart and order decisions within and across shopping sessions as well as interesting interaction effects of the promotion level and time since the previous shopping session on cart, order, and spending decisions. For example, promotions increase old cart recovery within a certain time period since the previous shopping session, but encourage new cart usage afterward. Our simulation results indicate that shopping cart abandonment is not always harmful to retailers, and that they should take a holistic approach to designing retargeting email promotions and focus on increasing consumer spending instead of maximizing shopping cart recovery.

Eye Tracking for Visual Marketing - Workshop

Eye-Tracking for Visual Marketing

Assessing and Improving The Effectiveness of Visual Marketing Using Eye-Tracking

As consumers, we are exposed every day to several hundreds of advertisements on television, in newspapers, magazines, the yellow pages, retail feature ads, and on the internet and mobile devices. The eyes guide consumers across shelves, through aisles, stores, malls, and websites when exploring, searching, and making decisions on products and brands. In all these situations “visual marketing” is relevant, that is, the strategic utilization by firms of commercial and non-commercial visual signs and symbols to communicate with consumers. As a consequence, there is an increasing need to measure visual attention through eye tracking technology, to assess the effectiveness of visual marketing. In the last decade there has been a rapid growth in commercial applications of eye-tracking technology in the United States, Europe, Asia, and Australia to assess the effectiveness of visual marketing efforts. Firms such as Kraft Foods, Microsoft, Google, Yahoo, IBM, Pepsico, Pfizer, P&G, and Unilever are leading users of the methodology in product and communication development, and in pre- and post-tests of their visual marketing activity. With the increasing demand from marketing practitioners, global providers of eye-tracking data conduct hundreds of studies each year.

This workshop provides the foundations of visual attention and eye tracking, and in particular (1) reviews the anatomy of the eye and the visual brain, (2) provides a conceptual framework for eye-tracking research in marketing and an overview of vision and attention, (3) reviews the marketing literature on eye tracking applications, and (4) provides a hands-on demonstration of the eye tracking technology.

Abstract

We provide the theory of visual attention and eye-movements that
serves as a basis for evaluating eye-tracking research and for discussing
salient and emerging issues in visual marketing. Motivated from its rising
importance in marketing practice and its potential for theoretical
contribution, we first review eye-tracking research for visual marketing.
Then, we discuss the structure of the eye, the visual brain, eye-movements,
and methods for recording and analyzing them. Next, we
describe our theory and review eye-tracking applications in marketing
based on it. We conclude with an outlook on future theory and method
development and recommendations for practice.

Can Excess Pay Be Explained Away?

This paper examines whether firms provide greater compensation-related textual disclosures to better explain the compensation awarded to their senior management team. Applying a textual analysis based approach to parse the contents of proxy statements for balanced scorecard related keywords and phrases, we create a text-based score and find that it is highly associated with the incidence of higher compensation. We then look at the Say-on-Pay setting, to assess whether greater textual performance disclosures are considered credible by shareholders when they cast their advisory votes on executive compensation. We find that firms that provide more compensation-related textual disclosures have a higher probability of obtaining SoP approval (i.e. over 70% support). We also find that firms that fail to obtain SoP approval provide greater disclosures in the following period. Finally, we find evidence suggesting that providing greater disclosures in response to past SoP disapproval increases the probability of obtaining an approval in the next SoP vote.

Information Networks: Evidence From Illegal Insider Trading Tips?

Finance

Speaker: Kenneth Ahern

28 May 2015


This paper exploits a novel hand-collected dataset to provide a comprehensive analysis of the social relationships that underlie illegal insider trading networks. I find that inside information flows through strong social ties based on family, friends, geographic proximity, and ancestry. On average, inside tips originate from corporate executives and reach buy-side investors after three links in the network. Inside traders earn prodigious returns of 35% over 21 days, with traders farther from the original source earning lower returns, but higher dollar gains. More broadly, this paper provides some of the only evidence on information networks that employs direct observations of person-to-person communication.
