Are Government Activities Productive? Evidence from a Panel of U.S. States
利用1970-1986年美国48个州的面板数据，考察政府资本和经常性服务对私人产出的贡献，发现当前教育服务有生产性，但其他政府活动无显著生产性，政府资本甚至常呈负效应。
Using panel data for the forty-eight contiguous U.S. states in each year between 1970 and 1986, this paper investigates the extent to which government capital and current government services contribute to private production. The paper finds fairly strong evidence that current government educational services are productive but no evidence that the other government activities considered are productive. Indeed, government capital often has statistically significant negative productivity. The results are robust across the many specifications considered. Copyright 1994 by MIT Press.
