This paper applies meta-regression analysis to take stock of the results of auditing research examining the premium charged by the Big audit firms. The Big firm premium is overstated in research taken as a whole, as a result of publication bias, but publication bias is not so strong as to completely eliminate evidence of a remaining premium. While the mean of the reported results is more than 23%, after eliminating publication bias the result is closer to 13%. The premium is significant in the United States listed companies, but not in other settings around the world. The study examines variables related to the publication process and the researchers, finding that, while there is no evidence that researchers with Big firm affiliations are subject to greater publication bias, the status of the journal and the researcher does make a difference. Meta-regression analysis has potential to lead to revised views of many areas of accounting and auditing research.
