The substantial reductions in motor vehicle emissions that have occurred since the late 1960s have been accompanied by continuous increases in vehicle emission control costs, and cost increases or decreases due to changes in vehicle performance such as driveability, power, fuel economy, and...

This paper presents results of an empirical study of emission banking for light-duty vehicle manufacturers. An intertemporal model of manufacturers' choices is combined with econometrically estimated abatement cost functions to simulate the cost savings and emission effects of an averaging,...

Recent data indicate that many U.S. areas still fail to meet national ambient air quality standards (NAAQS) for one or more criteria pollutants. In 1990, ninety-six U.S. metropolitan areas violated the federal ambient ozone standard, and forty-one areas violated the standard for carbon monoxide...
