Gender earning gap on digital platforms
Contrary to initial expectations derived from traditional labor market theories, which predicted digital platforms would narrow the gender earnings gap, recent studies suggest this gap remains persistent. This research focuses on Airbnb, where trust and hospitality, often perceived as favoring female hosts, play a critical role. Using data from Airbnb in Tel-Aviv and supported by experimental evidence, we find a surprising result: the gender earn…
Predicting human decisions with behavioural theories and machine learning
The influence of attractiveness and convenience cues on food appeal in adults with and without ADHD
The evolution of trust in Airbnb
The Effect of Experience on Context‐dependent Decisions
Does the well‐documented “decoy effect” emerge in decisions from experience among risky options? We conducted a series of experiments where participants made choices between gambles, and we varied whether participants learned about the options from description, experience, or both. Our results consistently showed no traces of the decoy effect when participants learned from experience. Even when participants read precise descriptions of the option…
Trust and reputation in the sharing economy
The Emergence of “Us and Them” in 80 Lines of Code
Psychological explanations of group genesis often require population heterogeneity in identity or other characteristics, whether deep (e.g., religion) or superficial (e.g., eye color). We used agent-based models to explore group genesis in homogeneous populations and found robust group formation with just two basic principles: reciprocity and transitivity. These emergent groups demonstrated in-group cooperation and out-group defection, even thoug…
A choice prediction competition
Erev, Ert, and Roth organized three choice prediction competitions focused on three related choice tasks: One shot decisions from description (decisions under risk), one shot decisions from experience, and repeated decisions from experience. Each competition was based on two experimental datasets: An estimation dataset, and a competition dataset. The studies that generated the two datasets used the same methods and subject pool, and examined deci…
Loss aversion, diminishing sensitivity, and the effect of experience on repeated decisions
Three experiments are presented that explore the assertion that loss aversion and diminishing sensitivity drive the effect of experience on choice behavior. The experiments are focused on repeated choice tasks where decision makers choose repeatedly between alternatives and get feedback after each choice. Experiments 1a and 1b show that behavioral tendencies that were previously interpreted as indications of loss aversion in decisions from experi…
The rejection of attractive gambles, loss aversion, and the lemon avoidance heuristic
Replicated alternatives and the role of confusion, chasing, and regret in decisions from experience
The current paper explores choice among alternatives that can be classified into distinct classes. All the members of a particular class were ‘replicated alternatives’: they promised the same payoff distribution. Information to decision makers was limited to feedback concerning the realized (obtained and foregone) payoffs. Experiment 1 demonstrates that increasing the number of replicated alternatives creates confusion (which facilitates random c…
