Specialization and Regulation: The Rise of Professionals and the Emergence of Occupational Licensing Regulation

This paper explores the origins and effects of occupational licensing regulation in late nineteenth and early twentieth century America. Was licensing regulation introduced to limit competition in the market for professional services at the expense of efficiency? Or was licensing adopted to reduce informational asymmetries about professional quality? To investigate these hypotheses, we analyze the determinants of licensing legislation and the effect of licensing on entry into eleven occupations. We also examine the impact of medical licensing laws on entry into the medical profession, physician earnings, mortality rates, and the incidence of medical malpractice. We believe that, at least for the Progressive Era, the evidence is more consistent with the asymmetric information hypothesis than the industry capture hypothesis.

The Origins of State Pure Food Regulation

Why did state governments begin to regulate the food industry in the late nineteenth century? One possible explanation is that pure food regulation was the result of rent seeking on the part of traditional food producers who wanted to limit the availability of new substitutes. Another potential hypothesis is that regulation was desired because it helped solve an asymmetric information problem in the market for food products. I find the evidence to be more consistent with the latter hypothesis.

History, Institutions, and Cities: A View from the Americas

Every nation, formally or informally, defines and establishes the lines of political and fiscal authority among its national, regional, and local governments. Historically, centralized governments tend to restrict the power and autonomy of provincial and local governments. In this paper, we exploit the quasi‐experimental distribution of political institutions in the Americas caused by variation in European colonial experience to examine the impact of institutions on urban and local development, specifically on the degree of urban primacy, the size distribution of cities, the number and density of local government units, and the fragmentation of metropolitan areas. We argue that centralization of political power at the national level, as experienced in many countries in Latin America, contributes to urban primacy and a size distribution of cities favoring large cities. Additionally, even in more politically decentralized countries such as Canada and the U.S., variance in political centralization at the provincial (state) level over local governments led to significant divergences in urban primacy, the distribution of city sizes, as well as the form, number, and density of local governments. While we cannot rule out the importance of other factors, our findings suggest that political centralization affects spatial economic development.

The Strange Budgetary Politics of Agricultural Research Earmarks

This article explores how members of the House and Senate Subcommittees on Agricultural Appropriations use the appropriations process to earmark special grants for agricultural research projects without forming a majority logroll. It also shows how subcommittee members coerce the USDA into administering individual earmarked research grants even though the precise allocation of these grants does not have the force of law. This article makes an important contribution because it analyzes an institutional development within the appropriations process that has not been explored in the existing literature, and it examines the consequences that this development has had on the quality of USDA-funded agricultural research.

The Political Economy of Truth‐in‐Advertising Regulation during the Progressive Era

This paper explores the origins and effects of truth‐in‐advertising regulation during the Progressive Era. Was advertising regulation adopted in response to rent seeking on the part of firms that sought to limit the availability of advertising as a competitive device, or was advertising regulation desired because it furnished a mechanism through which firms could improve the credibility of advertising? We find the available evidence to be more consistent with the latter hypothesis.

What Do Revolving-Door Laws Do?

On the basis of evidence from state public utility commissions, we find that revolving-door laws—laws that restrict the post-government-employment opportunities of public sector workers, including public utility regulators—do not do much, at least with respect to electricity prices. In this paper, we take advantage of a quasi experiment afforded by the fact that revolving-door laws were introduced in different states at different times to investigate their effects on electricity prices. Our findings suggest that while revolving-door laws temporarily dampen industrial electricity prices, they have no effect on commercial or residential prices. There is also some evidence that these regulations affect the characteristics of state public utility commissioners; commissioners from states with revolving-door regulations serve shorter terms and are less likely to be subsequently employed in the private sector, compared with their counterparts from states without revolving-door laws.

The Labor-Market Effects of Occupational Licensing Laws in Nursing

We study the labor-market impacts of occupational licensing laws on nursing, an economically important occupation. States adopted licensing of registered and practical nurses at different times, which allows us to estimate the effects of licensing on wages and participation for each nursing profession. We find that licensure raised wages by 5 to 10 percent but there is no evidence that it reduced overall participation. Additionally, we show that licensure equalizes wages within the occupation with minority wages rising faster than nonminority wages; however, licensing had a negative but not statistically significant impact on the participation of minorities in nursing.
