Welfare Estimation Using the Fourier Form: Simulation Evidence for the Recreation Demand Case
在需求函数形式未知时，利用傅里叶形式估计福利指标，证明估计量在弱假设下一致，并通过模拟验证等价变异的渐近偏差较小。
The paper considers the estimation of welfare measures when the functional form of demand is unknown. An adaptation of an argument of Gallant (1987) is used to show that welfare estimators based on a Fourier functional form for demand will be consistent under weak assumptions. Simulation evidence is presented for equivalent variation. True demand is a generalized Box-Cox function, estimated demand is a Fourier form, and equivalent variation is estimated by applying Vartia's (1983) algorithm to the estimated demand function. The estimator of equivalent variation has small asymptotic bias in the case of the assumed family of data generating processes. © 1997 by the President and Fellows of Harvard College and the Massachusetts Institute of Technology
