Preferences among alternatives capable of being expressed entirely in terms of money or money income .A and a riskless alternative B consisting of a certain income I0
U (A) = aU(I1)+ (1-a) U (I2)
I(A) capable of being expressed entirely in terms of money or money income . = aI1 + (1-a)I2
and indeed U-U(I) may be taken to measure the utility it attaches to this particular risk.
Describing a conceptual experiment for determining the utility function.
To get the utility attached to any income outside the interval $500 to $1000, say $10,000 .
