参考答案

正确答案：younger labor force
younger labor force 解析：由题于关键词John Schmitt and Dean Baker，1982 reflection，定位到原文第五段第一句后的括号内：Though the unemployment rate never reached the 10.8 percent of late 1982，economists John Schmitt and Dean Baker have shown this mostly reflected the 1980s' younger labor force；younger workers change jobs more often and have higher jobless rates. 可知，尽管失业率末从未达到1982年底的10.8%，但是经济学家约翰·施密特和迪安·贝克已经说明了这种主要体现在20世纪80年代的年轻劳动力，年轻的工人经常换工作，有较高的失业率，故答案填younger labor force。
