World Sleep Day: RAND Experts Available to Explain Why Insufficient Sleep Is Costing U.S., UK and Other Major Economies Hundreds of Billions of Dollars

March 13, 2018

In the run-up to World Sleep Day (Friday 16 March 2018), Marco Hafner, a senior economist at RAND Europe, and Wendy Troxel, a senior behavioral and social scientist at RAND, are available for interviews to talk about the significant economic costs of insufficient sleep.

They are co-authors of “Why sleep matters—the economic costs of insufficient sleep,” which found that insufficient sleep among the U.S. working population is costing the economy up to $411 billion a year, which is 2.28 per cent of GDP.

The study was the first of its kind to quantify the economic losses due to lack of sleep among workers in five different countries—the U.S., UK, Canada, Germany and Japan. It used a large employer-employee dataset and data on sleep duration from those countries to quantify the predicted economic effects from a lack of sleep among its workforce.
