"The objective of this paper is to better understand the manner in which the supply of labor in a regional economy adjusts to changing labor demand. The principal response mechanisms include changed rates of labor force participation, changed unemployment rates, and migration....[Following a review of] the relevant literature...the simultaneous relationships among participation, unemployment, employment, and migration are formally recognized in a 10-equation model of the regional labor market adjustment process. The model is estimated for a sample of about 350 U.S. counties over the period 1960 to 1970."
