Although increases in earnings that result from Employment and Trainin
g (E&T) programs typically come at the cost of losses of leisure to pa
rticipants, this is almost never taken into account in cost-benefit an
alyses of E&T programs. This paper develops a method for adjusting for
this bias and illustrates how the method can be used to reassess find
ings from earlier E&T cost-benefit analyses. Results in the paper sugg
est that the bias from ignoring lost leisure is likely to be sizable u
nless the E&T program that is subject to cost-benefit analysis increas
es earnings mainly by raising wage rates or participant reservation wa
ges are near zero, Ignoring the bias will favor E&T programs that emph
asize increases in hours of work by focusing on job search or work req
uirements at the expense of programs that increase wage rates through
investments in human capital.
