Charitable giving responses to education budgets
研究美国K-12教育预算变化如何影响教师通过DonorsChoose.org平台获得的私人捐赠，发现预算增加会挤出私人捐赠，但幅度很小。
Abstract Do changes in government spending affect voluntary contributions to those recipients? We examine how changes in K‐12 education budgets impact donations to teachers using data from DonorsChoose.org, an online crowdfunding platform for public school teachers to raise money. We find a positive correlation between budgets and voluntary contributions when not accounting for their endogenous relationship. Estimates using instrumental variables show evidence for crowd‐out of private giving, though the magnitudes are small relative to spending and do not meaningfully offset budget changes. These results are driven entirely by teachers' posting of requests.
