We compare two tradable permit markets in their ability to meet a safety first environmental target at least cost when some polluters have stochastic, correlated, and non-measurable emissions. In both markets, the point source permit defines the allowable level of the observed (deterministic)...

We report results from an economic experiment where two markets institutions for controlling water pollution are compared. In the status quo institution, permit trades between point and nonpoint sources are subject to a trading ratio. In the alternative, nonpoint abatements are converted into...

The Environmental Protection Agency and the U.S. Department of Agriculture are promoting point/nonpoint trading as a way of reducing the costs of meeting water quality goals while giving nonpoint sources a larger role in meeting those goals. Farms can create offsets or credits in a...

We compare two tradable permit markets in their ability to meet a stated environmental target at least cost when some polluters have stochastic and non-measurable emissions. The environmental target is of the safety-first type, which requires probabilistic emissions control. One market is built...
