This paper examines the relationship between the environmental complia
nce and financial performance of large US companies. The environmental
performance is measured in penalties assessed for violations of envir
onmental regulations. The financial performance is represented by the
profit margins. The regression models developed in this paper suggest
that the degrees of environmental compliance have a positive influence
on the profit margins. Conventional economic wisdom is that regulatio
ns impose costs and restrictions and, therefore, put companies at a co
mpetitive disadvantage. However, this paper is consistent with the pro
ponents of environmental regulations who argue that tough regulations
force companies to be innovative and as a result make them more produc
tive.
