Two nested constant-elasticity-of-substitution models of recreational participation and site choice: An "alternatives" model and an "expenditures" model

Two demand models of recreational participation and site choice are develop ed: an alternatives model and an expenditures model. Both assume maximizati on of utility over the year, so allow for diminishing marginal utility They do not impose the restrictive assumption that where one goes on a trip is independent of where one plans to go on other. occasions. Estimation is wit h a nested constant-elasticity-of-substitution preference ordering: it is r elatively easy to estimate because of global regularity it allows sites to be complements, and ii has tile potential to be locally flexible. The appli cation is to Atlantic salmon fishing.
