Supposed that two nation start out in 2013 with identical levels of output per work hour – say, $100 per hour. In the first nation, labor productivity grows by 1 percent per year. In the second, it grows by 2 percent per year. Use a calculate or spreadsheet to determine how much output per hour each nation will be producing 20 years later, assuming that labor productivity growth rates do not change.
