Another useful result in this regard is the comparative efficiency of antitrust policy in an LM economy. In Steinherr (1975b) it is argued that expenditures a LMF would be willing to incur to prevent or circumvent antitrust regulations are likely to be less than in a CF. The argument runs as follows: the relevant shadow price for a CF(l1) is the marginal profit to the firm of liberalizing antitrust legislation whereas in the LMF it is the marginal addition to income per labour (l2). Comparing l1 and Ll2 it is clear that l1 l2 meaning that a CF expects higher gains from the absence of antitrust regulations than dose the average worker when he casts a vote in a LMF.
