Decision Making Under Uncertainty - Risk Aversion

Consider five individuals Ulises, Vanesa, Walter, Zack, and Matthew. Their vN-M utility functions are given in Table 1. The first and second derivatives of their utility functions, as well as the absolute risk aversion index are also given in the Table.

\fUlises is risk |:| (averse / lover / neutral) because the second derivative of his utility function is :' (positive / negative / zero) Walter is risk I: (averse / lover/ neutral) because the second derivative of his utility function is l:| (positive / negative / zero) Zack is risk I:' (averse / lover/ neutral) because the second derivative of his utility function is |:| (positive / negative / zero) Matthew is risk :' (averse / lover / neutral) because the second derivative of his utility function is :l (positive / negative / zero) Ulises l:' (is more risk averse than / is less risk averse than / has the same degree of risk aversion of) Vanesa because his absolute risk aversion measure is :' (larger than / less than /equal to) that ofVanesa. Vanesa |:I (is more risk averse than / is less risk averse than / has the same degree of risk aversion of) Walter because her absolute risk aversion measure is :' (larger than / less than /equal to) that of Walter
