Why Are More Women Working in Britain?
利用英国女性年龄组数据，分析二战后至1977年女性劳动参与率上升的原因，发现兼职机会增加、家务时间减少、工资上涨及服务业扩张等因素起重要作用，适合关注女性就业和劳动供给的研究者。
Using a pooled time series, cross section supply function for single year age groups of Britain women, it is determined that female labor force participation rose steadily from World War II to 1977. Until the 1970s, the main increase was among married women aged 35 and over. Possible explanations for the post World War II rise in female labor participation are: 1) part time jobs were more available to women, 2) the drop in real prices of domestic appliances, processed foods, and easy care fabrics reduced the time required to take care of a family, and 3) the effect of long term changes in the roles women see for themselves in life. Women's wages rose sharply between 1973 and 1975, by around 15%; this was due to the Equal Pay Act of 1970. In addition, the educational attainment of women relative to men was constant or declining for cohorts entering the labor force up to the 1960s. Age specific employment rates are explained by 3 kinds of variables: 1) those whose values change from year to year and are age specific--life cycle variables, 2) those whose values change from year to year but affect all ages equally--calendar time variables, and 3) those that differ between cohorts but do not change over the life cycle--cohort variables. Results show that: 1) each preschool child lowers participation by 35% each primary school child by 14% and each secondary school child by 7%; 2) the relative earnings of women are highest early in life, 3) age leads to a decline in participation at an increasing rate, and 4) vacancies registered at employment exchanges are more or less untrended between 1950 and 1974. Completed family size, education, and early unemployment and wartime work experience do not explain the strong trend in the coefficients on the cohort dummies; however, real wages do. In time series, men's wages and women's wages are highly correlated, and each is nearly as highly correlated with time. During the 1970s, the female/male ratio index in each industry rose by 4.5 percentage points, reflecting the vast expansion of service industries. There were also sharp increases in the proportion of women workers within each industry, in spite of the sharp rises in women's pay.
