To determine whether the individual will work or go to college in first period, we need to compare the present value of the income from each option going to college or working over the two periods.
01:04
We use the discount rate of 40 % to calculate the present value here for the person without a college education is first income during the first period equals to $120 ,000 income during second period.
02:25
Here we have $12 ,000 present value of income for the non -college graduate.
02:52
We have present value equals to $120 ,000 plus $12 ,000 divided by 1 plus 0 .40 circumflex 4 equals to $44 ,444 .04 is the present value for the college graduate income during the first period.
04:20
From the given question, cost of college education is minus $200 ,000 that is negative because it is an expense.
