Recent vs. 2008 and 2001 recessions.<\/p>\n
In the 2001 and 2008 recessions, the Sahm Rule (real time) threshold is passed when unemployment is rising mostly due to rising unemployment count (and not due to rising labor force). Figures 1 and 2 show the real time Sahm Rule measure (black line) vs. decomposition of contributions to change in unemployment rate.<\/p>\n

That all can show up in changes in the unemployment rate, which is the core of the Sahm Rule.\u201d<\/p>\n<\/blockquote>\n \u00a0<\/p>\n<\/p><\/div>\n![\"\"](\"https:\/\/econbrowser.com\/wp-content\/uploads\/2024\/08\/sahm_2001.png\")
