Added worker effect : ウィキペディア英語版 | Added worker effect The added worker effect refers to an increase in the labor supply of married women when their husbands become unemployed. Underlying the theory is the assumption that married women are secondary workers with a less permanent attachment to the labor market than their partners. As statistics show, married women do not always behave as secondary workers; therefore, the effect is not a universal phenomenon. == Origin of idea ==
The concept of “additional workers” appeared in empiric studies on unemployment in the United States during the Great Depression conducted in 1940 by economists Wladimir S. Woytinsky and Don D. Humphrey (Humphrey, 1940, p. 412). Humphrey's study did not find any observable added worker effect, but it did not deny that added workers participated in the market (Humphrey, p. 415). He challenged the validity of Woytinsky's study in the absence of a time series analysis.
