Analytic Approach 23<br />
<strong>The</strong> differences between the two sets of results estimate the effects of <strong>in</strong>creased educational<br />
atta<strong>in</strong>ment on government revenues over an <strong>in</strong>dividual’s lifetime, hold<strong>in</strong>g his or<br />
her characteristics constant.<br />
We use a similar approach <strong>to</strong> estimate the effects of <strong>in</strong>creased educational atta<strong>in</strong>ment<br />
on the costs of subsidized hous<strong>in</strong>g. We use the model of hous<strong>in</strong>g subsidy utilization<br />
<strong>to</strong> estimate the probability that an <strong>in</strong>dividual with given demographic characteristics<br />
and education level would utilize assisted hous<strong>in</strong>g <strong>in</strong> each year of his or her life<br />
<strong>from</strong> school-leav<strong>in</strong>g age <strong>to</strong> age 79. Assum<strong>in</strong>g that the unit hous<strong>in</strong>g cost per person is<br />
constant across education levels and demographic groups, the expected hous<strong>in</strong>g subsidy<br />
is equal <strong>to</strong> the likelihood of utilization, as predicted by the model, times the average<br />
program cost per person. We then discount the estimates for each year of an <strong>in</strong>dividual’s<br />
life <strong>to</strong> age 18, us<strong>in</strong>g appropriate survival rates. <strong>The</strong> result is an estimate of the<br />
present value at age 18 of the assisted hous<strong>in</strong>g benefits that would be paid <strong>to</strong> an <strong>in</strong>dividual<br />
<strong>from</strong> that demographic group between school-leav<strong>in</strong>g and age 79, given his or<br />
her education level. We then compare the results for an <strong>in</strong>dividual with a given level of<br />
education and characteristics aga<strong>in</strong>st the correspond<strong>in</strong>g results for an <strong>in</strong>dividual with<br />
the same characteristics but a higher level of education. <strong>The</strong> differences between the<br />
two sets of results estimate the effects of <strong>in</strong>creas<strong>in</strong>g the <strong>in</strong>dividual’s level of education<br />
on the assisted hous<strong>in</strong>g benefits paid an <strong>in</strong>dividual over his or her lifetime, hold<strong>in</strong>g his<br />
or her characteristics constant.<br />
For each of the other social support and <strong>in</strong>surance programs, we use the probit<br />
model for that program <strong>to</strong> estimate the likelihood that an <strong>in</strong>dividual with given characteristics<br />
and education level will participate <strong>in</strong> that program <strong>in</strong> each year of his or her<br />
life <strong>from</strong> school-leav<strong>in</strong>g age <strong>to</strong> age 79. We then use the model of the annual <strong>in</strong>come<br />
the <strong>in</strong>dividual will receive <strong>from</strong> that program if they participate <strong>in</strong> any given year. We<br />
multiply the likelihood that the <strong>in</strong>dividual will participate <strong>in</strong> the program <strong>in</strong> each year<br />
by the estimated benefits that the <strong>in</strong>dividual would receive <strong>in</strong> that year if he or she participated<br />
<strong>to</strong> estimate the expected value of the program benefits paid <strong>to</strong> the <strong>in</strong>dividual<br />
<strong>in</strong> each year. We discount the estimates for each year of an <strong>in</strong>dividual’s life <strong>to</strong> age 18,<br />
us<strong>in</strong>g appropriate survival rates. <strong>The</strong> result is an estimate of the present value at age 18<br />
of the benefits an <strong>in</strong>dividual <strong>from</strong> that demographic group will receive between school<br />
leav<strong>in</strong>g and age 79, given his or her education level. We then compare the results for an<br />
<strong>in</strong>dividual with a given level of education and characteristics aga<strong>in</strong>st the correspond<strong>in</strong>g<br />
results for an <strong>in</strong>dividual with the same characteristics but a higher level of education<br />
<strong>to</strong> estimate the effects of educational atta<strong>in</strong>ment on the program’s costs over the <strong>in</strong>dividual’s<br />
lifetime, hold<strong>in</strong>g his or her characteristics constant.<br />
As noted previously, we model per-person correctional spend<strong>in</strong>g as the product<br />
of per-person <strong>in</strong>carceration expenditure and the likelihood of <strong>in</strong>dividual <strong>in</strong>carceration,<br />
assum<strong>in</strong>g that the probability of <strong>in</strong>carceration equals the number of prisoners <strong>in</strong> each<br />
population category divided by the sum of the general population and the number
