Abstract
Despite theoretical arguments that partnerships are the most efficient ownership form for professional service
firms (PSFs), PSFs are increasingly moving to other ownership structures, such as publicly listed companies
(PLCs). Research on the comparative performance of PSF, PLCs and partnerships is sparse with conflicting
results suggesting that some segments of PSFs are moving to a less efficient form. This study explores the
performance of two Australian accounting PLCs compared to a sample of similar sized mid tier accounting
firms. The accounting PLCs achieved substantially higher revenue growth rates but lower productivity than
the partnership sample. Measurement issues were identified in the use of closing resource numbers and
different treatment of reporting merger and acquisition revenues which may partially explain the
underperformance of publicly owned PSFs in prior studies. The need for research at a more detailed level
exploring the market and service focus, organisational structures, resources utilised and resource costs across
different PSF ownership forms is suggested.
