A Greater Price for a Greater Good? Evidence that Consumers Pay More for Charity-Linked Products
研究消费者是否愿意为附带慈善捐赠的产品支付更高价格，基于eBay上相同产品的慈善与非慈善拍卖数据，发现慈善拍卖价格平均高出6%，且竞拍者更早出价，表明慈善收入具有公共品属性。
To study whether consumers will pay more for products that generate charitable donations, we analyze data from eBay on charity and noncharity auctions of otherwise identical products. Charity prices are 6 percent higher, on average, than noncharity prices. Bids below the closing price are also higher, as are bids by individuals bidding on identical charity and noncharity products. Bidders appear to value charity revenue at least partially as a public good, as they submit bids earlier in charity auctions, stimulating other bidders to bid more aggressively. Our results help explain why firms may pledge charitable donations, green production, or similar activities.
