Fundamental flaws of social regulation: The case of airplane noise

This article provides an economic assessment of federal regulatory policy toward airplane noise as encapsulated in the 1990 Airport Noise and Capacity Act (ANCA). This act mandated the elimination of certain aircraft, such as the Boeing 727 and DC-9, from all U.S. airports by the end of 1999 to meet quieter noise requirements. We find that the present discounted benefits of the ANCA, reflected in higher property values for homeowners, fall $5 billion short:of the ANCA's cost to airlines, reflected in the reduced economic life of their capital stock. More fundamentally, we find that the net benefits that could have been generated by an economically optimal airplane noise tax amount to only $0.2 billion (present value). It appears that noise regulations have generated substantial costs to society when, in fact, there was little justification on efficiency grounds for regulatory intervention in the first place.
