Bundling Private Complements to Finance Public Goods
研究了通过提高门票和征税休闲装备来资助公共土地维护的两种方案，发现当征税商品与公共服务是弱互补品时，征税商品需求增加可作为判断福利改善的充分统计量。
The U.S. National Park Service and other agencies argue that our recreation lands face a crisis of deferred maintenance. This article evaluates two proposals for funding public lands: increasing gate fees and taxing recreational gear. It analyzes the joint welfare effects of such taxes and the services supported by the revenue. It shows that when the taxed goods and the public service are weak complements, there is a simple, sufficient statistic determining whether the joint effect increases welfare for both consumers and sellers: the quantity demanded for the taxed good increases. We illustrate these results with data for recreational services.
