This study examines the influence of urban design, neighbourhood built and social environment, and household and individual factors on the interdependent relationship between objectively measured physical activity and sedentary behavio...

Like blighted urban areas, indigenous nations in the U.S. often have abandoned underutilized commercial or industrial properties with potential environmental contamination within the confines of their reservations.

This paper contributes to the empirical literature on the relationship between environmental regulation and firm behavior. In particular, we ask whether and how strongly investment decisions of firms respond to stringency in environmental regulation. Environmental stringency is measured as (i) an industry’s total current expenditure on environmental protection, and (ii) a country’s revenue from...

Centralized collection and disposal is an integral component of waste management strategies for many solid and liquid wastes, and carbon capture and storage is currently being considered for gaseous waste. In this paper we show how collective waste disposal systems introduce essential changes in the design of optimal environmental policy. Absent collective disposal, an optimal environmental pol...
