Conyon, Martin and Machin, S (1991) Market-Structure and the Empirical Specification of Profit Margins. Economics Letters, 35 (2). pp. 227-231. ISSN 0165-1765Full text not available from this repository.
We present evidence from a panel of U.K. manufacturing industries to test the sensitivity of the margins-concentration relationship to specification changes in the dependent variable. Instrumental variable estimates demonstrate that a positive association between profit margins and concentration is contingent on how the margin is formulated.
