Abstract
Public intermediaries responsible for the management of uncertain water supply and demand face a number of decision problems. These include decisions with regard to water procurement and storage, capacity expansion, general operations, investment in demand side management programs, and pricing, among others. This thesis addresses two questions central to the water intermediary's management objective, both related to pricing. The first question is that of an optimal pricing policy in the presence of storage and both demand and supply uncertainty. There is an extensive literature treating the question of optimal public pricing in the presence of joint demand and supply uncertainty with specific application to the electricity sector (peak-load pricing). This literature assumes nonstorability of goods. The presence of storage is a defining feature of the water problem. We treat the pricing problem in the presence of storage, in a joint inventory-price control framework. We characterize the optimal pricing policy and investigate its sensitivity to a number of key model parameters, including the cost of water shortage. The second pricing model developed in this thesis treats option contracting in the water market. Reliance on option contracts is a relatively new phenomenon in the California water market. These contracts can be invoked to avoid costly shortfalls in supply faced by both urban and agricultural water agencies. As such, they can serve an important risk management role in the water market. Option contracts institute temporary transfers with lower transaction cost and lower institutional resistance than permanent transfers. Hence, in addition to providing a risk management tool, they may stimulate the water market by encouraging reliance on short-term water transfers. We price the water option contract from the seller's perspective and from a social planner's perspective. We then investigate the sensitivity of the contract prices and quantity to shifts in a number of contract parameters, including the presence of an outside option for the buyer and possible access to a spot market for water. Finally, we investigate changes to the contract prices and quantity in the presence of multiple buyers and sellers, where the latter requires consideration of strategic interactions between sellers.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
