This paper exploits the seasonal and annual changes in marginal prices for water to estimate the price elasticity of demand by residential households for water. It uses the changes in distributions of water using the census block group levels in response to changes in marginal prices of water...

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...

Urban ecologists have extended the bounds of this field to incorporate both the effects of human activities on ecological processes (e.g., humans as generators of disturbances), and the ways in which the structures, functions, and processes of urban ecosystems, and human alterations to them, in...

This paper outlines a new framework for gauging the properties of quasi-experimental estimates of the willingness to pay (WTP) for changes in environmental and other non-market amenities. As a rule, quasi-experimental methods cannot offer alternative hypotheses to judge the quality of their...
