Effects on Wage Rates: An Interim Analysis
分析西雅图和丹佛收入维持实验中财务和人力处理对家庭户主工资率的影响，发现几乎没有证据表明这些处理对工资率有显著效应。
Examined in this paper are the effects of the financial and manpower treatments of the Seattle and Denver Income Maintenance Experiments on the wage rates of original heads of families (husbands, wives, and single female heads). The results indicate that there is little basis for concluding that either the financial or manpower treatments have had any effect on wage rates. In addition to using a simple dummy variable model, we have examined the effects on manpower program participants and have investigated the possibility of a shift to higher-paying occupations. In the estimates of these models, significant response coefficients appear only about as often as would occur by chance alone.
