Another component of the demand function for outdoor recreation is
the critical on-site cost, c*. Recreationists had a good idea as to the
minimum length of stay at the. site. Thus, critical on-site cost was esti-
mated by obtaining the minimum number of days recreationists were willing
to recreate, other things being equal. This corresponds to the maximum price
they would be willing to pay on a demand curve. The minimum number of days,
y*, was substituted into Equation (10), which was then solved for c. The
minimum number of days, y*, 'was calculated to be 2.78 days for all periods.
The critical on-site cost, c*, was calculated to be $17.77. This is the
maximum amount of on-site costs a recreationist would pay to engage in
outdoor recreation given his travel cost and income.
The demand function for recreation, on the average, can be written
as:
(11) y = e1.929 .051c for c < $17.77
