Early school start times are arbitrary, forced on teens against their nature, and a poor economic decision as well, writes a professor of pediatrics in the New York Times.
Since it would take at least a year for any students affected by changes in start times to enter the labor market, there would be no gains in the first year. Costs, however, would accrue immediately. These included about $150 per student per year in transportation costs and $110,000 per school costs in upfront infrastructure upgrades. Even so, by the second year, the benefits outweighed the costs. By 10 years, the benefits were almost double the costs; by 15 years, they were almost triple.
