In his Man, Economy, and State, Murray Rothbard introduces the catallactic function of decision-making owner, and the correspondent income of decision-making ability rent. These are supposed to exist both in ERE (they are, therefore, distinct from the capitalist function and his income, from labor and wages, or land and the corresponding rent) and in the real world permeated by uncertainty (they must also be different from the entrepreneurial function and profit and loss). Even though these concepts seem to suggest an important breakthrough into the theory of the firm, we argue that they are problematic. They must dissolve into (at best, be elaborations of) either the standard economic functions present in the ERE (such as labor, for instance), or the entrepreneurial function.
