Abstract: | There has been significant concern in auditing about the effects of relying on prior working papers in planning audit procedures (“anchoring”). This study employed an experiment with varying information sets: prior working papers, current year information and “scenario” (summarized prior year information). Practicing auditors were asked to design a substantive audit program for a case where changes in the client's environment dictated additional procedures. A consensus program from three partners was used as a bench-mark. Experimental groups were about equally adaptive to the changing environment. However, auditors provided with prior working papers demonstrated lower efficiency. The scenario group exhibited both high relative effectiveness and efficiency, while current information subjects displayed the lowest overall level of performance. |
