Unemployment Insurance (UI) is the major public insurance program in the United States that protects families against the dangers of involuntary job loss. This report examines the impact of changes made to Michigan’s UI program in 2011 on program access for Michigan’s unemployed workers. Based on analyses conducted on state-level administrative data, study findings are consistent with the conclusion that the 2011 changes to Michigan’s UI program have reduced the number of short-term unemployed workers who access state program benefits. The changes are associated with between a 19.2% and 34.8% reduction in the UI recipiency rate for Michigan’s short-term unemployed. This report further documents that the reduction in state benefit weeks from 26 to 20 caused workers to lose additional weeks from related federal UI programs, which were prorated based on the number of benefit weeks offered by states.
