Ryan Oprea (UC Santa Barbara) – Simplicity Equivalents
Mai 28 @ 11 h 00 – 12 h 15

Abstract:

We provide evidence that classic lottery anomalies like probability weighting and loss aversion are not special phenomena of risk. They also arise (and often with equal strength) when subjects evaluate deterministic, positive monetary payments that have been disaggregated to resemble lotteries. Thus, we find, e.g., apparent probability weighting in settings without probabilities and loss aversion in settings without scope for loss. Across subjects, anomalies in these deterministic tasks strongly predicts the same anomalies in lotteries. These findings suggest that much of the behavior motivating our most important behavioral theories of risk derive from complexity-
driven mistakes rather than true risk preferences.

Agne Kajackaite (University of Milan) – Breaking bad: Malfunctioning control institutions erode good behavior in a cheating game
Mai 30 @ 10 h 45 – 12 h 00

This paper studies whether malfunctioning (or unenforced) institutions erode good behavior. We use a large-scale online experiment, in which participants play a repeated observed cheating game. When we ask participants to report honestly and promise no control, we find low cheating rates. When control of truthful reporting is introduced, low cheating rates remain. In our main treatment with a malfunctioning institution, participants do not know whether they are in the treatment with or without control. In this treatment, participants who do not face control for some rounds start cheating significantly more often, reaching highest cheating rates. That is, a malfunctioning institution leads to more cheating than no institution at all, which indicates that the development of cheating behavior is endogenous to the institutions. Our findings suggest a novel negative effect of unenforced laws.

César Hidalgo (Toulouse School of Economics) – Economic Complexity: past, present, and future
Juin 11 @ 10 h 30 – 11 h 45

For more than a decade, economic complexity has been a flagship application of machine learning methods to questions of sustainable growth and development. In this talk I will introduce the main methods used in the field, connect them to their related concepts in AI, and explore recent and upcoming research in economic complexity. I will conclude by discussing new research directions in the field including the use of economic complexity methods to questions of economic history and digital trade.
