An uptick in the jobless rate from 5% to 6% decreases the amount of time high-school students choose to spend on homework by about 19 minutes per week, says Steven McMullen of Calvin College in Grand Rapids, Michigan. That's because a higher unemployment rate diminishes expected labor-market returns, thus reducing the value of human-capital investment. For similar reasons, a $1 rise in the minimum wage in a state increases students' homework time by about 21 minutes per week, McMullen says.
