Price and Income Elasticities of Residential Water Demand: A Meta-Analysis
通过元分析方法，综合了文献中关于居民用水需求价格和收入弹性的实证估计，探讨了理论方法、时空动态和研究设计差异如何影响弹性估计结果，对政策制定者和水资源管理者有参考价值。
<i>This article presents a meta-analysis of variations in price and income elasticities of residential water demand. Meta-analysis constitutes an adequate tool to synthesize research results by means of an analysis of the variation in empirical estimates reported in the literature. We link the variation in estimated elasticities to differences in theoretical microeconomic choice approaches, differences in spatial and temporal dynamics, as well as differences in research design of the underlying studies. The occurrence of increasing or decreasing block rate systems turns out to be important. With respect to price elasticities, the use of the discrete-continuous choice approach is relevant in explaining observed differences.</i>
