An individual must choose between 4 insurance policies, x1,x2,x3,x4x_{1}, x_{2}, x_{3}, x_{4} , where x1x_{1} is the company's default option. The utility the individual receives from each option is ordered the following way: u(x3) >u(x1) u(x2) >u(x4) u\left(x_{3}\right) >u\left(x_{1}\right) \geq u\left(x_{2}\right) >u\left(x_{4}\right) . Which option does the individual choose?


A) x1x_{1}
B) x2x_{2}
C) x3x_{3}
D) x4x_{4}

Refer to Figure 4.3. Bundle x\mathrm{x} and y\mathrm{y} both have more of good I\mathrm{I} than reference points r\mathrm{r} and s. The curve vsv_{s} traces out the difference curve when using reference point s. Let Δ1\Delta_{1} be the amount of good j\mathrm{j} the individual must be given in order to be indifferent between bundle y\mathrm{y} and bundle x\mathrm{x} under reference point s\mathrm{s} . Let Δ2\Delta_{2} be the amount of good j\mathrm{j} the individual must be given to give up the SAME amount of good i under reference point rr . Which of the following is true?


A) Δ1Δ2\Delta_{1} \leq \Delta_{2}
B) Δ1=Δ2\Delta_{1}=\Delta_{2}
C) Δ1<Δ2\Delta_{1}<\Delta_{2}
D) Δ1>Δ2\Delta_{1}>\Delta_{2}

What is the difference between the status quo bias and the default option bias?


A) No difference.
B) The default option bias is a bias that occurs when there is a preference for a default option and a status quo bias is a bias that results from a preference for the currently chosen option.
C) The default option bias is a bias that occurs when there is a preference for a default option and a status quo bias is a bias for what other individuals have chosen.
D) The default option bias is a preference for failing to pay back loans, whereas a status quo bias is a bias that results from a preference for the currently chosen option.
