刚做完,楼主参考一下吧。大致的解题过程和思路我写在纸上了,具体的模型估计结果和图表在压缩文件包里,在里面还有用来生成这些图表的Stata的Code。
关于最后一问由于是essay question,我就不写了哈,不过大意有3点,楼主自己展开吧
1. LE of high income > Le of low income
2. The effect of income on LE is stronger for low income people than for high income people
3. LE of low income people is more sensitive to change of income than LE of high income people
