There is substantial heterogeneity in risk preferences estimated from the full-insurance model, positively …We measure heterogeneity in risk aversion among households in Thai villages using a full risk-sharing model and … correlated in most villages with portfolio-choice estimates.

Can measured risk attitudes and associated structural models predict insurance demand? In an experiment (n = 1,730), we … various risk-attitude measures.
