Historically, water allocation focused on quantities demanded by consumptive uses. As quantity demand grows, efficient allocation among consumptive and nonconsumptive uses becomes more critical. This hedonic approach provides information regarding recreational and aesthetic (RA) value for a central Texas lake. The model indicates several statistically significant RA characteristics of housing; ...
introduction: nowadays, efficient use of scarce water resources is one of the government’s importantgoals for dealing sustainable development in the agricultural sector. in addition to optimal exploitation and using of surface and groundwater resources, choosing of efficient types of irrigation technologies is a very important factor in sustainable water resource management. this study tries to...
Estimating water demand in urban Indonesia: A maximum likelihood approach to block rate pricing data
In this paper the Burtless and Hausman model is used to estimate water demand in Salatiga, Indonesia. Other statistical models, as OLS and IV, are found to be inappropiate. A topic, which does not seem to appear in previous studies, is the fact that the density function of the loglikelihood can be made arbitrary high if observations are located exactly on a kink of the budget constraint. To avo...
Feasting on Leftovers: Strategic Use of Shortages in Price Competition Among Differentiated Products
T single-product firms with different quality levels and fixed limited capacities engage in sequential price competition in an essentially deterministic model where customers have heterogeneous valuations for both products. We develop conditions under which the leader (she) can take strategic advantage of her limited capacity by pricing relatively low, purposefully creating shortages and leavin...
A commonly observed two-stage pricing strategy for a custom-made product involves a prepurchase entry fee for a potential consumer and a purchase price if he decides to buy the product. We solve and compare two settings: In the first, the firm does not commit in advance to the second-stage price and in the second, the firm does. We show that without a commitment mechanism, the two price points ...
To specify demand in most water allocation problems, researchers face a tradeoff between flexibility and parsimony. Flexible forms are less constraining on elasticity estimates, but require large parameter sets that tend to cause poor out-of-sample forecasts and computational difficulties. Using a five-year panel of Texas municipalities, the parsimonious Stone-Geary form yields estimated demand...
This paper has two objectives. First, we identify a problem with the ability of the discretecontinuous choice framework and conditional demand functions to fully describe consumer preferences in the presence of kinked budget constraints. Second, we propose and illustrate an alternative, preference-based method for estimating consumer responses to price changes under these conditions. This frame...
Stable modeling in water resources management requires recognizing the relations between the different uses of water and their long-term results on one hand and taking into account the current and future access to water resources and demands for them, on the other hand. In recent years, Hamedan-Bahar plain has been identified as one of the restricted groundwater areas in Hamedan province. In t...
The objective of this study is to provide estimates of price elasticities of irrigation water demands in Zhangye Basin (ZB), an inland river basin in China, with the most recent data and to compare the values of marginal product (VMPs) of water to the prices of water farmers are currently paying. With a set of village and household survey data collected in 2009 and 2014, household fixed effects...
