We test the effect of stake size on ambiguity attitudes. Compared to a baseline condition, we find subjects to be more ambiguity seeking for small-probability gains and large-probability losses under high stakes. They are also more ambiguity averse for large-probability gains and...

Risk-aversion has generally been found to decrease in income. This may lead one to expect that poor countries will be more risk-averse than rich countries. Recent comparative findings with students, however, suggest the opposite, giving rise to a risk-income paradox. This paper tests this...

We obtain rich measures of risk preferences of poor farmers in Vietnam, and estimate structural models that capture risk preferences over different probability levels and across different domains (gains and losses). The results break radically with the previous literature on risk preferences, in...

Attitudes towards uncertainty have been indicated to be highly context-dependent, and to be sensitive to the measurement technique employed. We present data collected in controlled experiments with 2939 subjects in 30 countries measuring uncertainty attitudes through incentivized measures as...
