Title of talk: Self-Constraint and the Demand and Supply of Paternalism

Type of talk: Research Presentation

Language: English

Abstract:  People may approve of behaviourally informed public policies because these may help them avoid their own errors or judgment (demand for paternalism) or help others avoid such errors (supply of paternalism). In two pre-registered experiments involving delayed monetary rewards, we find extensive evidence of self-constraint and a large supply of paternalism, but very limited demand. Although people broadly believe others are like themselves, this projection does not induce them to demand the constraints they are so ready to offer.　Evaluating people’s acceptance of paternalism based on self-constraint or supply considerations may greatly overestimate people’s willingness to accept externally imposed constraints.

Title of talk: Pre-Registration and Pre-Analysis Plans in Experimental Economics

Type of talk: AI-Accelerated Research Procedure

Language: English

Abstract:  

In other sciences, "Self-driving Labs" are emerging. In economics, we mainly use AI for ad-hoc tasks like proofreading, missing its strategic potential. This gap presents a critical window of opportunity. I propose we seize this first-mover advantage by building an AI-Native Research Team to systematically embed AI across our entire research lifecycle. This presentation will outline a potential model. The primary goal is to gather feedback from colleagues and recruit volunteers for an initial "pioneer team." Let's collaborate to build a framework that significantly boosts our productivity and positions our team as a leader.

Title of talk: A game of status: gender asymmetry in loss aversion

Language:  English

Type of talk:  Research Presentation

Abstract:

This study examines gender differences in loss aversion to status. Drawing on data from over 14,000 Grand Slam matches in professional tennis, I introduce a novel measure—the Net Tournament Balance (NTB)—which quantifies how far a player is, in ranking points, above or below the reference point at which their current world ranking is maintained. To identify causal effects of placement in the “loss” domain on performance, I employ a regression discontinuity design. The findings reveal a pronounced gender difference: male players exhibit strong status-based loss aversion. They become significantly more likely to win and adopt a more aggressive playing style when facing the threat of status decline, consistent with prospect theory. In contrast, female players show no comparable behavioral adjustment relative to this reference point. Additional analysis suggests that culture, social norms, and identity may contribute to male players’ sensitivity to status loss.

Title of talk: “Will” it be Seen? Using Eye-Tracking to Reexamine the Future Tense Effect in Intertemporal Choices

Language:  English

Type of talk:  Research Presentation

Abstract:

The Linguistic-Savings Hypothesis (LSH) suggests that weak future tense marking in language promotes future-oriented behavior, though empirical evidence remains inconsistent. This study investigates the cognitive mechanisms underlying the LSH using eye-tracking and the Drift-Diffusion Model (DDM). In a double-blind intertemporal choice experiment with Chinese speakers, we manipulated linguistic presentation by introducing a future tense marker ("jiang") versus a neutral control. While aggregate behavioral data showed a non-significant trend supporting LSH, eye-tracking analysis revealed a critical attentional mechanism: increased fixation duration on the future tense marker significantly predicted a reduced likelihood of choosing delayed rewards. Computational modeling further indicated that the future tense marker alters the decision process by biasing the starting point toward immediate rewards. These findings suggest that linguistic markers influence intertemporal choices not merely through cultural association, but by capturing attention and inducing an immediate-reward bias during early cognitive processing, providing micro-level evidence supporting the LSH.
