A Cross-Country Comparison of Decentralization and Environmental Protection
Hilary Sigman presents a cross-country analysis of the relationships between decentralization and environmental quality. She employs four measures in her study: (1) access to improved sanitation; (2) wastewater treatment; (3) ambient sulfur dioxide; and (4) the size of protected land areas. The results show no consistent effects of decentralization on environmental quality. Although decentralization seems to decrease access to sanitation, it increases the amount of land allocated to protected areas. In both cases, however, the estimated values of the coefficients used in Sigman’s econometric model are not statistically significant.
