Description
Summary:Audit risk is the risk that an auditor may unknowingly fail
to modify appropriately the auditors' report on financial
statements that contain a material misstatement. However,
because an indisputable value for audit risk cannot be
determined, the auditor must gather evidence about the
financial statements and, based on his or her professional
judgment, develop an estimate of true audit risk. Because the
estimation of audit risk depends on an auditor's professional
judgment, it is of interest to describe how auditors evaluate
and aggregate audit evidence. A number of models have been
proposed to accomplish this. Although each model to some
degree may be descriptive of the judgment process, the
underlying basis of each model is quite different. Depending
on the model, the auditor may aggregate evidence differently
and make different evaluations. Therefore, an estimate of
audit risk calculated using one model may be affected by
influences to which other models are not sensitive. This
study examines in a quasi-experimental setting three models
descriptive of the audit judgment process: the Audit Risk
model (ARM), the Dempster-Shafer Belief Functions model
(DSBF), and the Hogarth and Einhorn Belief Adjustment model
(HEBA). Specifically, the sensitivity of each model to
differences in the order in which internal control
information is obtained, and the effects of different levels
of change in internal control effectiveness are examined.
Additional analysis examines the degree to which each model
is descriptive of the judgment process and a comparison of
models is made. The responses of eighty-five subjects
indicate that the HEBA model is sensitive to the order in
which evidence is obtained whereas the ARM and the DSBF
models are not. None of the models displayed sensitivity to
different levels of change in control effectiveness. For the
ARM and the HEBA models, the data indicates a linear
relationship between subjects' responses and corresponding
values predicted by the model. While the mean level of
estimated audit risk was significantly different for the
three models, the percentage difference between subjects'
responses and corresponding values predicted by each model
were not significantly different.
