Social assistance and labour supply
利用1988-89年加拿大LMAS纵向数据，通过Tobit模型和FIML估计，发现社会救助福利对劳动时间有微小但统计显著的影响，尤其对女性。
The longitudinal, 1988–89 LMAS makes it possible to study the interaction between social assistance and labour supply while allowing for substantial time dependence. Tobit equations for hours worked on and off social assistance, which allow for endogenous selection of social assistance status, are estimated by using FIML. Small, but statistically significant, effects for a social assistance benefit variable are obtained, particularly for females. A claw‐back variable is not consistently useful. The wage rate has a consistently negative coefficient in the selection equations and is important in the Tobit equations. In this paper an attempt is made to reconcile results found in earlier literature.
