Consider yourself as a risk neutral worker picking between two jobs.

The basic set up is as in the class notes. In job

A

there is a $50\%$ chance

of wages being $16$ or $20$ while in job

B

wages are equally likely to be

$8$ or $24.$ What job

A

pays is independent of what job

B

pays so that

learning about either job teaches you nothing about the other. You are

indifferent between the jobs. The question concerns your willingness

to pay up front for knowledge and your search strategy. There is no

discounting so that your objective is to maximize expected wages net

of learning cost
