POLLUTION-ABATEMENT EXPENDITURES AND REGIONAL MANUFACTURING ACTIVITY

Using a sample of 63 SMSAs for the years 1974, 1978, and 1982 1 find weak support for the argument that environmental regulations retard economic activity. Regression analysis of the relationship between per unit total and air pollution abatement expenditures in the manufacturing sector of these SMSAs and manufacturing employment and earnings levels reveals that these associations are negative but that the magnitudes are relatively small. For example, 10 percent higher per unit total pollution abatement costs are associated with, on average, 1064 fewer manufacturing workers (0.17 percent of total regional employment) in Sun Belt SMSAs during 1982.
