需要と供給
Supply and demand theories do not provide sufficient explanation regarding women's absence in industrial firms after the war. It is wrong to associate patriotism with the war-time women workers since some housewives quit their jobs at early periods of the war when the country needed their help the most. Some of the housewives were forced to quit as the second highest lay-off rate belonged to them. If their only concern was the well-being of their country at the war time, less persistence to exit would have been observed.
