Emergency workers (employees of federal contracyclical programs such as WPA) were counted as unemployed on a normal-jobs-to-be-created instead of job-seekers unemployment definition. For 1934-1941, the corrected unemployment levels are reduced by two to three-and-a half million people and the rates by 4 to 7 percentage points. The corrected data show strong movement toward the natural unemployment rate after 1933 and are very well explained by an anticipations-search model using annual full-time earnings. ER -
