The dominant paradigm of conservation-reserve planning in economics is to optimize the provision of physical conservation benefits (measured in units like species protected) given a budget constraint. Large-scale biology-based priority setting implies that the value we place on biodiversity and...

Using data from 1995 and 1996, we estimate the cost of the Arizona Enhanced I/M Program and the emission reductions achieved. We begin by enumerating briefly the components of I/M costs and discuss their size and incidence. Then we describe the empirical information from Arizona and how we use...

The expense and inconvenience of enhanced vehicle emissions testing using the full 240-second dynamometer test has led states to search for ways to shorten the test process. In fact, all states that currently use the IM240 allow some type of fast-pass, usually as early in the test as second 31,...

Many of the biggest environmental policies are federal: the Clean Air Act, the Clean Water Act, and so forth. Yet those federal laws leave important niches to be filled by state authorities; there are areas of environmental policy in which state governments can and should take the lead. Some...

This study compares subsurface drip irrigation and sprinkler irrigation with respect to expected returns, aquifer life, nutrient utilization and accumulation in the production of irrigated corn using swine effluent and fresh groundwater from a depleting aquifer in the Oklahoma Panhandle. Most of...

Recent studies have suggested that green technologies may be a cost effective way to manage urban runoff. Literature has also suggests that there needs to be a greater empirical basis to estimate the benefits associated with social values associated with urban trees; we therefore estimate...

We explore the efficiency of allowing participants in transferable-rights programs to sell credits in multiple markets, i.e., to double dip. In a first-best economy double-dipping is efficient, but if the cap is set suboptimally, then the answer depends on the relative slopes of the marginal...

The study explores the implications of climate change for the economic costs of ecological conservation and restoration of submerged aquatic vegetation. It develops a methodological framework that addresses the key issues of uncertainty, irreversibility and space in climate change and...
