medium level of desirable site characteristics while Group III had a low
level of desirable characteristics. Sites that occurred in Group III
perhaps had only a boat ramp or at most simple picnic facilities while
those of Group I were characterized by restaurants, motel accommodations,
and other such amenities.
APPLICATION OF THE MODEL
The theoretical model can now be written as:
(5) Y = Y [(T*- T), (C* C)] for T* T> 0
C* C > 0
(6) T* = T* (C, m, s)
(7) C* = C* (T, m, s)
where s is the site characteristic and is used as a surrogate for
utility, U.
The three equations can be solved simultaneously to obtain a
relationship between the independent variables in the T* and C*
equations and the dependent variable Y. The latter can be estimated
directly to obtain the demand relationship. The dependent variable
(Y) is defined as the number of visitor days a recreational group
spends at the recreation site per trip. Thus Y = ny, where y is the
number of days per person per visit and n is the size of the recreation
group. Since Y is determined by two separate variables, a per capital
equation to utilize a single dependent variable is:
(8) y = y (t, c, m, s, n) for C < C*
