Empirical findings of recent labor market research are used in this article in the construction of theoretical models of the wage and employment behavior of the firm in an unorganized labor market. Four cases are discussed: the firm with labor requirements fixed over a range of wage rates; a firm with labor needs varying with wage levels; employment discrimination between groups of workers with different characteristics; and promotion from within.
