Are government expenditures more cyclical the more they finance the provision of public goods?
研究了政府支出中公共品属性（非竞争性）越强，其周期性是否越强。利用28个OECD国家1997-2019年数据，发现经济衰退时政府会将支出从公共品转向私人品，导致公共品支出更易波动。
Abstract The “publicness” of services provided by governments can be gauged with reference to the extent to which services are “non‐rival in consumption.” Services that are more “rival in consumption” (e.g., education and medical care) are more likely to be “parceled out” between citizens. With greater personal experience, voters are more likely to be aware of private‐good benefits and therefore are far more likely to perceive these services as part of a personal “endowment.” In economic downturns, they attach priority to sustaining expenditures on more “private” services and vote‐maximizing governments respond by diverting expenditure from “more public” to “more private” services. Consequently, government expenditures are more cyclical the more they finance non‐rival services. Predictions are tested with reference to government expenditures in 28 OECD countries between 1997 and 2019.
