Title: Multiple Expectations, Disappointment, and Risk Measures: A Unifying Model of Decision under Risk
- VIDEO (64 min, 139MB)
Abstract: The Disappointment theory of choice under risk is built on the standard assumption that individuals form a prior expectation about a risky prospect, and they will experience disappointment, hence a reduction in utility, if the outcome obtained falls below the expectation. Here, a different approach to Disappointment will be developed: we abandon the hypothesis of a well-defined prior expectation and we propose instead that disappointment may arise from comparing the outcome received with any of the prospect’s missed outcomes. This yields a new, general model of choice under risk, which bridges a number of classic theories that have evolved from distinct intellectual paths. First, our Disappointment without Prior Expectation (DWPE) model leads to Rank Dependent Utility, a popular model based on subjective probability transformation. Second, DWPE produces a general class of Risk-Value models, including Mean-Variance or the Mean-Gini model. This is an appealing structure because managers often seek to rank projects in terms of two criteria: reward and risk. We show the conditions for our risk measure to satisfy first- and second-order stochastic dominance and coherence, key properties required for prescriptive applications, e.g. in Finance, Insurance, or R&D portfolio selection. Results from calibration of the model to experimental data will be presented. In sum, DWPE provides a unifying, plausible behavioral rationale for a number of landmark theories of choice under risk, and it offers advantages for practical risk management.
This is joint work with Alessandra Cillo (IESE Business School, Barcelona)

Speaker: Rebecca Hamilton and Michel Wedel (Marketing dept.)
Title: Conducting Research in the Behavioral Lab
Abstract: In this session, Rebecca Hamilton will provide an overview of the Netcentric Behavioral Lab’s resources for conducting behavioral research. The 18 workstations in the main lab space allow researchers to develop and run electronic surveys and experiments, collect reaction time data, and record Internet clickstreams. The new AudioVisual Lab allows researchers to study team interactions while recording both verbal and nonverbal communication. Examples of research conducted in the lab will be provided to illustrate the lab’s capabilities.
Michel Wedel will also talk briefly about the lab’s two Tobii eye trackers, which allow researchers to study how people process information presented to them via websites, print advertisements, and even dynamic formats such as video clips or TV ads.

Title: Poisson & Beyond Double Session
Abstract: 1) Simulating Multivariate Poisson Data , by Inbal Yahav (PhD student)
Generating multivariate Poisson data is essential in many applications. Current simulation methods suffer from limitations ranging from computational complexity to restrictions on the structure of the correlation matrix. We propose a computationally efficient and conceptually appealing method for generating multivariate Poisson data. The method is based on simulating multivariate Normal data and converting them to achieve a specific correlation matrix and Poisson rate vector. This allows for generating data that have positive or negative correlations as well as different rates. The talk consists of two integral parts. First, we present the method and its simplicity in general. We illustrate our results for different correlation structures and arrival rates. We then discuss issues with generating multivariate Poisson data with low arrival rates (lambda<1), for which the feasible correlation is no longer in the range [-1, 1]. We present a simple correction of our algorithm that enables generating multivariate Poisson data with low arrival rates.
(2) A Flexible Model for Count Data: CMP Poisson, Galit, Kim Sellers (Georgetown), and Seth Guikema (Johns Hopkins)
Count data are abundant in practice. However, the Poisson distribution appears to hold a near monopoly for purposes of modeling count data. We introduce the Conway-Maxwell Poisson, a 2-parameter generalization of the Poisson distribution, which can capture over- and under-dispersion. We then discuss recent work on developing CMP regression models (Galit and Kim Sellers will present a GLM model; Seth Guikema will present a Bayesian formulation).

Title: Spotfire hands-on tutorials for MBA students
Abstract: In response to requests from MBA students in BUDT733 (Data Mining for Business), we've designed a hands-on tutorial to help first-time users of Spotfire (an interactive visualization software, available in the lab). The session was taped on VHS. Contact Galit for details.
