Weekly Seminar: Andrea Robbett “Voter Expression and Information Acquisition in Common Value Elections” (Thursday, May 3rd, 2018)

Andrea Robbett is an Assistant Professor of Economics at Middlebury College. She received her PhD from Caltech in 2011. Her research uses lab experiments to address topics related to public economics, labor economics, social dilemmas, and voting. This talk will focus on a series of experiments investigating expressive voting and rational ignorance among American political partisans.

Weekly Seminar: Pietro Ortoleva, “Econographics” (Thursday, April 26, 2018)

We study the pattern of correlations across a large number of behavioral regularities, with the goal of creating an empirical basis for more comprehensive theories of decision making. We elicit 21 behaviors using an incentivized survey on a representative sample (n = 1,000) of the U.S. population. Our data show a clear pattern of high and low correlations, with important implications for theoretical representations of social and risk preferences. Using principal components analysis, we reduce the 21 variables to six components corresponding to clear clusters of correlations. We examine the relationship between these components, cognitive ability, demographics, and qualitative self-reports of preferences.

Weekly Seminar: M. Kathleen Ngangoue, “Learning from Unrealized versus Realized Prices”, (Thursday, April 19, 2018)

Our experiments investigate the extent to which traders learn from the price, differentiating between situations where orders are submitted before versus after the price has realized.  In simultaneous markets with bids that are conditional on the price, traders neglect the information conveyed by the hypothetical value of the price.  In sequential markets where the price is known prior to the bid submission, traders react to price to an extent that is roughly consistent with the benchmark theory.  The difference’s robustness to a number of variations provides sights about the drivers of this effect

Weekly Seminar: Fabio Maccheroni, “Multinomial Logit Processes and Preference Discovery: Inside and Outside the Black Box “, (Thursday, April 12, 2018)

We provide both an *axiomatic* and a *neuropsychological* characterization of the dependence of choice probabilities on deadlines in the softmax form, with time-independent utility function and time-dependent accuracy parameter.

The softmax model (also known as Multinomial Logit Model or Power Luce Model) is the most widely used model of preference discovery in all fields of decision making, from Quantal Response Equilibria to Discrete Choice Analysis, from Psychophysics and Neuroscience to Combinatorial Optimization. Our axiomatic characterization of softmax permits to empirically test its descriptive validity and to better understand its conceptual underpinnings as a theory of agents rationality. Our neuropsychological foundation provides a computational model that may explain softmax emergence in human multialternative choice behavior and that naturally extends the dominant Diffusion Model paradigm of binary choice.

Weekly Seminar: Alex Imas, “The Dynamics of Discrimination: Theory and Evidence”, (Thursday, March 22, 2018)

Alex Imas is a Visiting Assistant Professor of Behavioral Science at the University of Chicago Booth School of Business, and an Assistant Professor of Social and Decision Sciences at Carnegie Mellon University. Imas’ research spans a variety of topics across economics and psychology. He has studied how prior losses and gains affect risk-taking, the use of prosocial incentives to motivate performance, and the ways in which people use others’ emotions strategically.

 

 

Weekly Seminar: Daniel Martin, “”Inattention to Game Form: A Theory of the WTA/WTP Gap”, a joint work with Edwin Munoz Rodriguez, Northwestern (Thursday, March 15th, 2018)

Daniel Martin is an Assistant Professor in the Managerial Economics and Decision Sciences (MEDS) department at Northwestern University’s Kellogg School of Management.  He is a behavioral and experimental economist who studies the processing and disclosure of information.  For example, he investigates why firms do not voluntarily and clearly disclose information about product quality and why consumers do not pay full attention to information about prices or product quality.

Weekly Seminar: Christine Exley, “Motivated Framing Effects” (Thursday, March 8th, 2018)

Framing effects are often attributed to misperceptions.  In this study, however, we document a large and robust framing effect that is not reflective of misperceptions.  Our framing effect persists when agents gain experience, pay attention, and are provided with information that prevents miscalculations.  We propose and provide evidence as to why our framing effect persists: the majority is driven by self-serving motives.  Our results suggest that framing effects, as well as other behavioral biases driven by self-serving motives, may be notably robust to de-biasing conditions.
