The Political Economy of Saving Mothers and Babies: The Politics of State Participation in the Sheppard-Towner Program
研究了1922-1929年谢泼德-汤纳项目中各州参与度的差异，发现女性获得选举权的时间对参与有短期影响，但项目废止后该效应消失，且无示范效应。
Enacted in 1922 and repealed in 1929, the Sheppard-Towner program gave federal matching money to states to provide public health education to mothers. We examine variation in state participation in the program, and find that the timing of women's suffrage had an important impact. However, we find that the effect of suffrage was short-lived and did not influence public health spending after the program's repeal. We also find no evidence of a “demonstration effect.” On average, the states that continued activities after Sheppard-Towner ended were those that had sizable public health budgets before the program had even begun.
