Life, limbs, and licensing: occupational regulation, wages,

and workplace safety of electricians, 1992-2007

Licensing of electricians, as well as of the broader construction occupational group to which electricians belong, grew
significantly at the state levelfom 1992 to 2007.

Analysts of government policies in the labor market have long held that licensing laws which restrict
the supply of labor cause an increase in wages, but there has been little analysis of the influence of
regulation on the conditions of work. This article examines the influence of occupational licensing on
the wages and workplace safety of electricians, one of the most regulated occupations directly involved
in the construction industry.
   Occupational licensing is among the fastest growing institutions in the U.S. economy. In the 1950s,
about 4.5 percent of the workforce was licensed by state governments. By 2008 approximately 29
percent of the U.S. workforce was licensed by any level of government, and more than 800 occupations
were licensed by at least one state in the 1990s.1 The latter statistic compared with about 12.4 percent
of the workforce who said they were union members in the Current Population Survey (CPS) for the
same year.2-
   Occupational regulation in the United States generally takes three forms. The least restrictive form is
registration, in which individuals file their names, addresses, and qualifications with a government
agency before practicing their occupation. The registration process may include posting a bond or filing
a fee. In contrast, certification allows any person to perform the relevant tasks, but the government-or
sometimes a private, nonprofit agency-administers an examination or another method to determine
qualifications and certifies those who have achieved the level of skill and knowledge required for
certification. The toughest form of regulation is licensure, often referred to as the right to practice.
Under licensure laws, working in an occupation for compensation without first meeting government
standards is illegal. As examples of certification versus licensure, travel agents and car mechanics are
generally certified but not licensed.
   The focus of this article is the role of occupational licensing and other forms of government
regulation for electricians, a heavily regulated occupation in the construction industry. Unlike
previous work that examines the role of occupational licensing on wages, prices, and access to,
and quality of, regulated services for consumers,-' the research presented here extends the
analysis of regulation to the subject of the likelihood of occupational licensing reducing work-
related deaths and serious j ob-related injuries.
   The analysis presented finds that local licensing of electricians is associated with
approximately a 12-percent wage premium beyond that afforded by state regulations and that
certain aspects of occupational requirements of state licensing, such as age and education, as
well as exam requirements, raise the wages of electricians by about 6 percent to 8 percent.
These results are robust for several alternative specifications. Further, the findings suggest a
modest tradeoff between wages and work-related injuries. However, no systematic influence of
occupational licensing on the injury rates, severity of injuries, or death rates of electricians was
found. The rest of the article documents the development of these results.
