The effects of alternative enforcement strategies on the pollution control activities of the firm are investigated. There are a number of tradeoffs available to a firm including delay and non-compliance which allow it to minimize expected pollution control costs. These are identified within the context of a generalized behavioral model for the firm and an empirical study is undertaken to determine their importance. In a simulation of current enforcement of the federal new source particulate matter discharge standard for coal-fired power plants it is found that cost-minimizing power plants will install relatively costly pollution control technology and frequently violate federal fly ash standards. Two alternative enforcement strategies for overcoming these shortcomings, namely compliance tests in combination with emission taxes and emission taxes alone, are analyzed. In the case of the federal fly ash discharge standard for coal-fired power plants it is tentatively concluded that emission tax enforcement would probably result in an approximate minimization of the sum of firm and enforcement agency resource costs. The general applicability of this result to other enforcement problems is discussed.
