An empirical investigation of audit fees in the us for-profit healthcare sector

The purpose of this paper is to analyze the market for audit services for publicly traded companies operating in the US for-profit (FP) healthcare sector. Complex national and local healthcare laws and regulations suggest the importance of assessing fee effects of joint nationallevel and city-specific expertise among auditors. Using cross-sectional OLS regression analysis, we find that joint expertise significantly affects audit pricing in the healthcare sector. We find a fee premium of 33.6 percent on engagements where auditors are both national and city-specific specialists. We also find that Big-4 auditor reputation is significantly priced over and above the effects of joint auditor expertise, and a significant positive association exists between audit and non-audit service fees-indicating the presence of knowledge spillover effects among healthcare company auditors.
