Multiple Pathways of Visual Adaptations for Water Column Usage in an Antarctic Adaptive Radiation

open access: yesEcology and Evolution, Volume 15, Issue 3, March 2025.
By investigating the diversification of the visual system in notothenioids, we reveal lineages at equivalent depths often depict extremes in eye size with striking convergences in tuning sites between distantly related species that are likely driven by the unusual environmental conditions of the Southern Ocean.

Dynamics of allosteric transitions in GroEL

open access: yes, 2006
The chaperonin GroEL-GroES, a machine which helps some proteins to fold, cycles through a number of allosteric states, the $T$ state, with high affinity for substrate proteins (SPs), the ATP-bound $R$ state, and the $R^{\prime\prime}$ ($GroEL-ADP-GroES$)

Designing Team Projects for Envy‐Free Group Collaboration to Overcome Free‐Rider Problem

open access: yesDiscrete Dynamics in Nature and Society, Volume 2025, Issue 1, 2025.
We propose an envy‐free team project called “color team project”. The primary motivation behind this approach is to prevent free‐rider behavior and create a fair evaluation system that avoids jealousy among team members. In the team project, each team member indicates their contribution to the final team output using a color or their name.

How much do we learn? Measuring symmetric and asymmetric deviations from Bayesian updating through choices

open access: yesQuantitative Economics, Volume 16, Issue 1, Page 329-365, January 2025.
Belief‐updating biases hinder the correction of inaccurate beliefs and lead to suboptimal decisions. We complement Rabin and Schrag's (1999) portable extension of the Bayesian model by including conservatism in addition to confirmatory bias. Additionally, we show how to identify these two forms of biases from choices.

Mental Models and Learning: The Case of Base-Rate Neglect

open access: yesThe American Economic Review
We experimentally document persistence of suboptimal behavior despite ample opportunities to learn from feedback in a canonical updating problem where people suffer from base-rate neglect. Our results provide insights on the mechanisms hindering learning

How Do Firms Form Their Expectations? New Survey Evidence

open access: yesThe American Economic Review, 2015
We survey New Zealand firms and document novel facts about their macroeconomic beliefs. There is widespread dispersion in beliefs about past and future macroeconomic conditions, especially inflation.

Gradual learning from incremental actions

open access: yesTheoretical Economics, Volume 20, Issue 1, Page 93-130, January 2025.
We introduce a collective experimentation problem where a continuum of agents choose the timing of irreversible actions under uncertainty and where public feedback from the actions arrives gradually over time. The leading application is the adoption of new technologies. The socially optimal expansion path entails an informational trade‐off where acting

Everyday Econometricians: Selection Neglect and Overoptimism When Learning from Others

open access: yesAmerican Economic Journal: Microeconomics
This study explores selection neglect in an experimental investment game where individuals can learn from others’ outcomes. Experiment 1 examines aggregate-level equilibrium behavior.
