This paper measures heterogeneity in risk aversion among households in Thai villages using a full risk-sharing model and complements the results with a measure based on optimal portfolio choice. The authors find substantial heterogeneity in risk preferences estimated from the full-insurance model, positively correlated in most villages with portfolio-choice estimates.
