This paper develops a graphical analysis and an analytical model that demonstrate how weak substitution can be used for non-market valuation. Both weak complementarity and weak substitution can be evaluated as restrictions that allow quantity or quality changes in non-market goods to be...

The Urban Heat Island (UHI) provides direct evidence of how human activities contribute to a feedback loop that can result in multiple changes in ecosystem services by creating localized warming as well as differences in vegetated landscapes in areas surrounding the urban core. This paper...

The importance of increments to an existing highway system depends upon their contributions to the accessibility provided by the existing network. Nearly 40 years ago, Mohring [1965] suggested this logic for planning optimal highway investment programs. He argued it could be implemented by...

This paper has two objectives. First, we identify a problem with the ability of the discrete-continuous 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,...

Efforts to reconcile inconsistencies between theory and estimates of the income elasticity of the value of a statistical life (IEVSL) overlook important restrictions implied by a more complete description of the individual choice problem. We develop a more general model of the IEVSL that...

We explore the consequences of treating the multiple, non-market benefits associated with improvements in ecosystem health and the market economy from which damage to these ecosystems stems as an integrated system. We find that willingness to pay measures of use-based ecosystem services are...
