5.3. Conclusion
This paper contributes to auditing and information systems literature in three key ways: First, while prior research finds that strong IT capability reduces year-to-year audit fee growth in the post-SOX years (Masli et al., 2010; Chen et al., 2014), our findings indicate that companies with stronger IT capabilities pay higher audit fees in a given year. Second, our additional analysis suggests a revised view of Chen et al. (2014) may be warranted. For instance, it is possible that companies with superior IT capabilities may better adapt to exogenous shocks, including new auditing or accounting regulations, than companies that lack strong IT capabilities. Subsequently, the difference in audit fee growth attenuates as all companies adapt to the impact of new requirements over time. Third, our additional analysis suggests that larger companies with strong IT capabilities will pay disproportionately higher audit fees than smaller companies with strong IT capabilities. This diseconomy of scale may be of special interest to large companies with high IT sophistication, as they weigh the pros and cons of IT investment. It may also be of interest to the audit firms that audit these companies, as the auditors consider the necessary resources needed to audit clients with differing levels of IT capability.
