A trading ratio is required for water quality trading that involves nonpoint sources to compensate for the difficulty of determining nonpoint loadings, the stochastic characteristics of nonpoint loadings, and the uncertainty inherent in nonpoint source pollution control strategies. Compensating...

A demand system that includes five different beverages of various container sizes was estimated using a Censor Corrected Almost Ideal Demand System (CAIDS). Resulting elasticities provide information about intra-product relationships (same product but different sizes), intra-size relationships...

A spatially dynamic programming model of nonuniform irrigation is developed to investigate the nitrogen leaching problem associated with irrigated agriculture. We evaluate the importance of temporal and spatial elements in (i) appropriately modeling the interseasonal corn production problem with...
