A Switching Regression Approach to Spatial Patterns in Residential Water Demand


  • Théophile AZOMAHOU


This study explores spatial regimes variation and the impact of public sector wa ter pricing for municipality aggregate residential water demand including electricity price effe cts. I compare estimations from two cross-sections (1988.1 and 1993.1) on a French lattice samp le, and propose a parametric spatial autoregressive regime switching model where water a verage price is approximated by a linear spline based on nonparametric regressions. I f ind evidence of spatial dependence. Consumers respond to both water and electricity average p rice. Changes in electricity price induce modifications of water consumption distribut ion according to patterns of water use. Public sector pricing results in shifts of role in reg imes between periods.
