Fuel economy and motor vehicle emissions
Article Abstract:
A simple statistical model has been used to establish the relationship between fuel economy and motor vehicle emission standards through the analysis of 1991 statistics of about 67,000 light duty vehicles. The model, which considers a gram-per gallon scheme, revealed that a lower rate of of motor vehicle emissions of hydrocarbon and carbon monoxide tend to yield a better fuel economy. The proof also negated the assumption that 50% to 80% of vehicle emissions are caused by 10% of the vehicles. Instead, the proof established that a gas guzzler is capable of maintaining low emission rate through its life span, provided it is properly managed.

Information as regulation: the effect of community right to know laws on toxic emissions
Article Abstract:
Information can be used as a quasi-regulatory mechanism to change a polluting company's behaviour. Companies with the biggest stock price decline following disclosure of their toxic release inventory (TRI) emissions were found to decrease their TRI emissions more significantly than other companies in their industry after the information is made public. Such companies were found to have a lower chance of being fined by the government in the following years.

The economics of site investigation for groundwater protection: sequential decision making under uncertainty
Article Abstract:
A model to determine investigating groundwater pollution costs is developed. The model is based on the Variable Sample Size Sequential Probability Ratio test and evaluations reveals that the model is quite effective in reducing costs. Hydrological evaluations and environmental policies should be studied carefully as costs are irreversible and policy outcomes are uncertain.
