Revising Beliefs in Light of Unforeseen Events (2024)
Journal Article
Becker, C. K., Melkonyan, T., Proto, E., Sofianos, A., & Trautmann, S. T. (in press). Revising Beliefs in Light of Unforeseen Events. Journal of the European Economic Association,

Bayesian updating is the dominant theory of learning. However, the theory is silent about how individuals react to events that were previously unforeseen. We study how decision makers update their beliefs if unforeseen events materialize, and under w... Read More about Revising Beliefs in Light of Unforeseen Events.

Constant Discounting, Temporal Instability and Dynamic Inconsistency in Denmark: A Longitudinal Field Experiment (2024)
Journal Article

Claims that individuals have dynamically inconsistent preferences are usually made by studying individual discount rates over different time delays, but where those discount rates are elicited at a single point in time. However, to test dynamic incon... Read More about Constant Discounting, Temporal Instability and Dynamic Inconsistency in Denmark: A Longitudinal Field Experiment.

Intelligence Disclosure and Cooperation in Repeated Interactions (2024)
Journal Article

In recent years, there has been growing interest in capturing, manipulating, and analyzing the effects of decision-making processes that underlie economic choice. This editorial discusses these recent developments by contextualizing the six contribut... Read More about Investigations of decision processes at the intersection of psychology and economics.

Speed traps: algorithmic trader performance under alternative market balances and structures (2023)
Journal Article
Peng, Y., Shachat, J., Wei, L., & Zhang, S. S. (2024). Speed traps: algorithmic trader performance under alternative market balances and structures. Experimental Economics, 27(2), 325-350. https://doi.org/10.1007/s10683-023-09816-8

Using double auction market experiments with both human and agent traders, we demonstrate that agent traders prioritising low latency often generate, sometimes perversely so, diminished earnings in a variety of market structures and configurations. W... Read More about Speed traps: algorithmic trader performance under alternative market balances and structures.

Migration and Trust: Evidence on Assimilation from Internal Migrants (2023)
Preprint / Working Paper
Marino Fages, D. Migration and Trust: Evidence on Assimilation from Internal Migrants

I study whether internal migrants assimilate culturally to the locals. Investigating this question with observational data has been challenging because it requires disentangling assimilation from sorting and because data on immigrants before migratin...

Anger Impairs Strategic Behavior: A Beauty-Contest Based Analysis (2023)
Journal Article
Castagnetti, A., Proto, E., & Sofianos, A. (2023). Anger Impairs Strategic Behavior: A Beauty-Contest Based Analysis. Journal of Economic Behavior and Organization, 213, 128-141. https://doi.org/10.1016/j.jebo.2023.06.027

The frustration-aggression hypothesis posits that anger affects economic behaviour essentially by temporally changing individual social preferences and specifically attitudes towards
punishment. Here, we test a different channel in an experiment whe... Read More about Anger Impairs Strategic Behavior: A Beauty-Contest Based Analysis.

Blocking D2/D3 dopamine receptors in male participants increases volatility of beliefs when learning to trust others (2023)
Journal Article
Mikus, N., Eisenegger, C., Mathys, C., Clark, L., Müller, U., Robbins, T. W., …Naef, M. (2023). Blocking D2/D3 dopamine receptors in male participants increases volatility of beliefs when learning to trust others. Nature Communications, 14(1), Article 4049. https://doi.org/10.1038/s41467-023-39823-5

The ability to learn about other people is crucial for human social functioning. Dopamine has been proposed to regulate the precision of beliefs, but direct behavioural evidence of this is lacking. In this study, we investigate how a high dose of the... Read More about Blocking D2/D3 dopamine receptors in male participants increases volatility of beliefs when learning to trust others.

On the generalizability of using mobile devices to conduct economic experiments (2023)
Journal Article

Mobile devices enable experimental economists to collect decision-making data from more heterogeneous samples, thereby increasing the generalizability of their results. This generalizability may be compromised if the device is a relevant behavioural... Read More about On the generalizability of using mobile devices to conduct economic experiments.

Rice Farming and the Origins of Cooperative Behaviour (2023)
Journal Article
Zhou, X., Alysandratos, T., & Naef, M. (2023). Rice Farming and the Origins of Cooperative Behaviour. The Economic Journal, 133(654), 2504-2532. https://doi.org/10.1093/ej/uead030

This paper provides novel evidence for links between historic farming practices and current norms of cooperative behaviour. We hypothesise that the cooperation required in wetland rice farming gives rise to strong cultural norms of cooperativeness. W...

Are you experienced? How the time spacing of traders' market experience impacts bubble formation in experimental asset markets (2022)
Book Chapter
Shachat, J., & Wang, H. (2022). Are you experienced? How the time spacing of traders' market experience impacts bubble formation in experimental asset markets. In S. Füllbrunn, & E. Haruvy (Eds.), Handbook of Experimental Finance (267-280). Edward Elgar Publishing. https://doi.org/10.4337/9781800372337.00028

We demonstrate when market experience is spaced out over a longer period of time (weeks instead of minutes), the increase in pricing efficiency is very small - if at all - for the same population of traders. However pricing efficiency gains are subst... Read More about Are you experienced? How the time spacing of traders' market experience impacts bubble formation in experimental asset markets.
