Do Consumers React to the Shape of Supply? Water Demand Under Heterogeneous Price Structures.
Stavins, Robert N. "Do Consumers React to the Shape of Supply? Water Demand Under Heterogeneous Price Structures." KSG Faculty Research Working Paper Series RWP05-039, June 2005.
Abstract
We perform an empirical analysis of the influence of price and price structure on residential water demand, using the most price-diverse, detailed, household-level water demand data yet available for this purpose. Ours is the first analysis to address both the simultaneous determination of marginal price and water demand under block pricing, and the possibility of endogenous price structures in the cross section. We find that households facing increasing block prices may be more sensitive to price increases than households facing uniform marginal prices. Tests for endogenous price structures cannot rule out a behavioral response to the shape of supply, but suggest that observed differences in price elasticity under supply curves of varying shapes may result, in part, from underlying heterogeneity among utility service areas.
