After the American Civil War, agricultural reformers in the South called for an end to unrestricted grazing of livestock on unfenced land. They advocated the stock law, which required livestock owners to fence in their animals, arguing that the existing system (in which farmers built protective fences around crops) was outdated and inhibited economic growth. The reformers steadily won their battles, and by the end of the century the range was on the way to being closed.

In this original study, Kantor uses economic analysis to show that, contrary to traditional historical interpretation, this conflict was centered on anticipated benefits from fencing livestock rather than on class, cultural, or ideological differences. Kantor proves that the stock law brought economic benefits; at the same time, he analyzes why the law's adoption was hindered in many areas where it would have increased wealth. This argument illuminates the dynamics of real-world institutional change, where transactions are often costly and where some inefficient institutions persist while others give way to economic growth.

Workers' compensation was arguably the first widespread social insurance program in the United States and the most successful form of labor legislation to emerge from the early Progressive Movement. Adopted in most states between 1910 and 1920, workers' compensation laws have been paving seen as the way for social security, Medicare, unemployment insurance, and eventually the broad network of social welfare programs we have today.

In this highly original and persuasive work, Price V. Fishback and Shawn Everett Kantor challenge widespread historical perceptions, arguing that, rather than being an early progressive victory, workers' compensation succeeded because all relevant parties—labor and management, insurance companies, lawyers, and legislators—benefited from the legislation. Thorough, rigorous, and convincing, A Prelude to the Welfare State: The Origins of Workers' Compensation is a major reappraisal of the causes and consequences of a movement that ultimately transformed the nature of social insurance and the American workplace.
