Estimates of semiparametric equivalence scales
在Pendakur（1999）的半参数框架下引入新损失函数来估计等价尺度，利用参考和非参考家庭的总支出全部信息，得到更可靠的估计。使用1996年加拿大家庭支出数据，估计了食品、燃料和服装等支出类别的等价尺度。
Abstract Within the semiparametric framework introduced by Pendakur ( 1999 ) we introduce a new loss function to estimate equivalence scales. This loss function uses all available information from the total expenditures of both the reference and nonreference households and as such it produces more reliable estimates. Using Canadian family expenditure data for 1996 we apply this loss function to obtain equivalence scale estimates for a variety of expenditure share categories such as food, fuel and clothing.
