how the demand relationship would be different between time periods one
and two. The coefficient on DI indicates that one could expect recrea-
tionists to spend an additional 1.3 days recreating per visit in time
period two over time period one. Similarly, the length of stay would
decrease in both periods three and four compared with one.
Equation (9) is applicable to all types of recreation sites in the
Kissimmee River Basin. Due to the lack of a significant effect of site
characteristics in the model, s was not used in the final formulation
of Equation (9). It was concluded from evidence in this study that the
specific site characteristics did not enter into the decision concerning
the number of days a recreationist spends at a recreation site in the
Kissimmee River Basin.
Equation (9) contains on-site cost, travel cost,'income, number of
recreationists in the group, and the effects of time periods. In this
equation the sign of the coefficient of travel cost, t, is positive.
This indicates that as travel costs increase $10.00 the recreationist
will increase his stay at the site by 1.3 days.
The negative sign of the coefficient of on-site costs, c, indicates
that as the price of a day of recreation increases the number of days
spent at the recreation site will decrease. An increase of $1.00 will
result in a decrease in the number of days spent at the site of approx-
imately 1.1 days. Both the coefficients of travel cost and on-site
cost are significant at the 1 percent level.
The sign of the coefficient of m, the recreationist's income is
positive. This indicates that as incomes go up the number of days a
recreationist will spend at the site increases. For example, a
