The Rationalization of U.S. Farm Labor: Trends between 1956 and 1979.

Discussions of farm labor emphasize that much hired labor is of a low opportunity cost, "salvage" nature and that technological advance is reducing the need for labor in agriculture. However, these ideas do not explain a trend for an increasing proportion of hired farm workers to be employed for a longer duration or for family labor to decline at a more rapid rate than hired labor. This paper proposes that these trends can be explained by the technical and commercial development, or rationalization, of United States agriculture in line with goals of organizing resources to create a profitable set of commodities with manageable risk. The analysis has several empirical implications that are borne out by national-level relationships of trends in numbers of hired and family farm workers with technical change, commercialization, and unemployment.
