Consider a labor market where workers can signal their high ability (productivity) by acquiring education, and workers are paid according to their productivity a, conditional on their education level e (years of education). If a worker does not signal his/her ability through education, he/she is considered a low - ability worker. The productivity of high-ability workers is aH = 10 and their unit (yearly) cost of education is cH = 2, while the productivity of low-ability workers is aL = 2 and their unit cost of education is cL = 4. Which of the following levels of education e* allows high -ability workers to credibly signal their ability on the labor market? a. e* = 1 b. e* = 3 c. e* = 5 d. e* = 10 3.
