Which of the following would not affect labor supply?

Select the correct answer below:

immigration laws

government programs that provide childcare to working mothers

an increase in wage

long-term unemployment benefits

Second

Explanation:

Immigration laws tend to ease or restrain immigrants in entering the country and eventually seeking for jobs, leading to shift in labor supply. Increase in wage will both in the short and long run influence the supply curve by shifting it to the upper left in the long run or by going along it in the upper right direction. Long-term unemployment benefits if too large will have a demotivating effect on job seekers, thus changing labor supply in the long run.
