Summary/Goals:
The urban demand experiments are a multiple-phase series of experiments that investigate consumer decisions regarding water use under different demand management schemes. The primary goal is to identify consumer response to various policies before they are initiated, such as the change in price of water. This will allow more efficient policy design, and avoid the political and practical difficulties associated with "trying out" untested policies on the public. While the experiments cannot fully replicate real world behavior of an entire population, they can provide insight into consumer preferences as responses at relatively low dollar and time cost.

The phases are as follows:
Phase 1: These involved non-computerized/computerized experiments in which participants allocated an aggregate budget between water and cash. At this level, the participants did not have to specify exact uses of water, only the aggregate number of units they wished to buy under different price/income and climate scenarios.

Phase 2. These ask participants to specify precisely how they will use the water they choose to purchase. As in phase 1, prices and weather will vary. As prices increase, participants will observe their "virtual" water bill increasing, and will be asked to decide whether to allocate more cash to paying that bill and/or to make behavioral changes that reduce their use. In this phase, behavioral changes can include taking shorter showers, reducing the frequency of car washing or laundry, rescution of expenditures in other budget categories and other changes etc that do not require investment in water-saving appliances or landscape features.
Activities and outcomes during past year:
Phase 1: All experiments for phase 1 have been completed. Results have been presented at conferences. Manuscripts from the phase 1 analysis have been prepared. The results have guided development of phase 2. The phase 2 experiments were re-designed based upon initial beta testing. Significant more choice detail and budgetary realism was incorporated into the experiment. At this point, beta testing of the phase 2 is nearly complete. Experiments are expected to be run early 2008.

2008 activities: Conducted urban water pricing experiments. The objective of the experiments was to estimate consumer price response over a wider range of prices than have historically or are currently being employed. Our experimental participants were customers of the Albuquerque Bernalillo Water Utility Authority. Over ten experimental rounds, prices ranged from a commodity charge of $1.27 per unit (a unit equals 748 gallons) to over $20 per unit. 180 individuals participated in the ten experimental sessions.

Preliminary data analysis suggests consumer responsiveness increases with price. The average response at low prices (less than $10 per unit) was highly inelastic (e.g., 1.5% decrease in consumption for a 10% increase in price). However, at the highest price, average response was elastic: a 12.6% decrease in consumption for a 10% increase in price. In addition, the range of elasticities at each price level indicates consumers are heterogeneous. The factors of heterogeneity are currently being investigated.
