The Implications of Model Specification for Welfare Estimation in Nested Logit Models
研究嵌套Logit模型中嵌套结构、估计方法（FIML或序贯）以及跨组参数限制对福利估计的影响，并扩展模型选择准则和模拟标准误计算，适用于环境价值评估研究者。
Abstract Nested logit models are increasingly being used to value environmental amenities. The implications of nesting structure, choice of estimator (FIML or sequential), and restrictions on parameters across nested groups on welfare estimates are examined. These issues have received little previous attention. Model selection criteria that can be used to distinguish among the models are extended and applied. Additionally, a simulation procedure is implemented to construct standard errors for the welfare measures.
