The Institute of Justice, a Virginia-based libertarian law firm, has produced a new report, License to Work: A National Study of Burdens from Occupational Licensing, which it describes as "the first national study to measure how burdensome occupational licensing laws are for lower-income workers and aspiring entrepreneurs". The report focuses on licensing requirements for more than 100 occupations across the U.S., and concludes "on average, these licenses force aspiring workers to spend nine months in education or training, pass one exam and pay more than $200 in fees. One third of the licenses take more than a year to earn. At least one exam is required for 79 of the occupations." The report's executive summary suggests interior design is the most difficult of the occupations studied to enter, that Louisiana licenses the largest percentage of these occupations ,that the average licensing requirements are highest in Hawaii and lowest in Pennsylvania, and that Arizona and California are the "most widely and onerously licensed states."
