A Note on Estimating Nested Constant Elasticity of Substitution Preferences for Outdoor Recreation
提出一种基于计数数据的策略来估计户外休闲的嵌套常数替代弹性偏好，避免了多项选择方法中关于选择时机设定和解释的困难，并比较了两种方法的参数和福利估计结果。
A generalized version of a well‐known statistical result is used to suggest an alternative strategy for estimating nested constant elasticity of substitution preferences for recreation demand. Parameter and welfare estimates from nested constant elasticity of substitution count data demand system models are presented and compared to estimates from the multinomial approaches developed previously. A significant advantage of the count data estimation strategy over the multinomial‐based approaches is that the analyst avoids the difficulties associated with choice occasion specification and interpretation.
