A large literature examines men's unemployment and their wives' labor-market participation. In response to her husband's unemployment, a woman may adjust her labor supplied to household production as well as to the market. This article tests for this effect and measures its impact using the U.S. Bureau of Labor Statistics Cost of Living survey of 1917–1919. Households altered both household-production decisions and the wife's labor supplied to the market in response to the husband's unemployment. But the household-production-response effect was smaller than the added-worker effect, in terms of women's labor hours and household consumption.
