The Ill Effects of Public Sector Corruption in the Water and Sanitation Sector
研究发现，在85个国家1990-2004年的数据中，公共部门腐败与改善饮用水和充足卫生设施的获取率呈显著负相关，即腐败越严重，这些公共服务覆盖越差。
In general, given a particular set of institutions, the greater a county’s per capita income, the more extensive will be its provision of goods and services that require concerted public action. We contend that one of the most important aspects of institutions in this regard is public sector corruption. We test this contention by analyzing 85 countries observed in 1990, 1995, 2000, and 2004—the only years for which data on improved drinking water and adequate sanitation are available. The models point to statistically significant, negative relations between corruption and access to both improved drinking water and adequate sanitation. <i></i>
