Hall-Roeger tests of market power in Irish manufacturing industries

Abstract

The Hall-Roeger methodology for the testing of market power is applied to Irish manufacturing industries for the period 1991-1999. The paper adapts their methodology to permit discrimination between input and output-price-based sources of market power. The empirical results do not indicate much evidence of significant imperfect competition in output markets but the results do point to evidence of market power in certain input markets and in some industrial sectors. The implications of these findings are discussed.
