ABSTRACT: Measuring ambiguity attitudes with monetary incentives is logistically complex, costly, and time-consuming. We propose and validate a simplified, introspection-based method that retains the core strengths of state-of-the-art approaches for measuring ambiguity preferences while being suitable for survey implementation. The method involves a hypothetical binary choice between a risky and an ambiguous option, followed by an introspective assessment of the strength of preference. We assess its validity by comparing it to incentivized matching probability measures in two experiments: a laboratory study with university students and an online study with a representative sample of the French population. Our findings show that the introspection-based method reliably captures ambiguity aversion but falls short in measuring ambiguity-generated likelihood insensitivity. These results offer new evidence on the strengths and limitations of non-incentivized approaches to eliciting ambiguity preferences and highlight their practical value in empirical research beyond the lab.

BIO: María J. Montoya-Villalobos is a postdoctoral researcher at the University of Lille and Lille Economics and Management (LEM). Her research lies at the intersection of experimental and behavioral economics, environmental economics, and decision-making under uncertainty, with a focus on risk and ambiguity preferences and how uncertainty shapes pro-social and pro-environmental behavior and policy responses.
