The most obvious asymmetry between capital-managed firms and labor-managed firms is that the former are common while the latter are rare. However, some countries have substantial LMF sectors with hundreds or thousands of such firms, including Italy, Spain, France, and Uruguary. Empirical researchers have identified a number of patterns involving the behavior, performance, and design of LMFs. A satisfactory theory of the LMF should not only explain why LMFs are rare. It should also help to explain these additional patterns. This chapter begins a survey of the recent empirical literature on LMFs, with an emphasis on econometric research involving large national data sets. Topics covered include the distribution of LMFs across industries; the comparative static behavior of LMFs, such as their responses to changes in demand or cost conditions; the objective functions of LMFs, with a focus on the question of whether such firms maximize profit; productivity comparisons with conventional firms; and comparisons of the wage structures found in LMFs and conventional firms.
