Auditor's responses to changes in risk

This paper examines whether auditors plan engagements to be the same-as-last-year (SALY) and if they respond to changes in risk both before and during audit engagements by varying engagements from planned. These are important questions considering audit standards require the assessment of risk and general concerns about audit quality and fee pressure. We provide new insights using a proprietary database containing both quoted and reported audit hours and fees. We find that the basis quoted audit hours and billing rates (i.e., audit plans) are prepared on is not SALY. However, as there is little difference for audit hours, we conclude that they are based-on-last-year (BOLY). Changes in audit characteristics are associated with the variance between quoted and reported audit hours and billing rates. In addition, auditors with higher reputational risk quote more audit hours and have a higher quoted average billing rate and further increase them from quoted.
