有效的估计:使用神经网络构建伪面板

Efficient estimators : the use of neural networks to construct pseudo panels

Marie Cottrell, Patrice Gaubert

摘要:

由重复截面组成的伪面板是真实面板数据的良好替代品。但是,分组在一个队列中的个人是不相同的连续时期,它会导致测量误差和不一致的估计。解决的办法是将大量个体组成队列,但尽可能同质。本文解释了一种新的方法来做到这一点:通过使用自组织映射,其属性非常适合实现这些目标。它适用于一组加拿大的调查,以估计18个消费函数的收入弹性。

英文摘要:

Pseudo panels constituted with repeated cross-sections are good substitutes to true panel data. But individuals grouped in a cohort are not the same for successive periods, and it results in a measurement error and inconsistent estimators. The solution is to constitute cohorts of large numbers of individuals but as homogeneous as possible. This paper explains a new way to do this: by using a self-organizing map, whose properties are well suited to achieve these objectives. It is applied to a set of Canadian surveys, in order to estimate income elasticities for 18 consumption functions..
