This study examines how accounting conservatism may affect the information
environment of analysts’ earnings forecasts, taking into account the interaction between
unconditional and conditional conservatism. Unconditional conservatism preempts
conditional conservatism in the later period and reduces the uncertainty in loss
recognition associated with bad news. Through a simple analyst forecast model, I
demonstrate that: 1) unconditional conservatism is negatively correlated with analysts’
forecast errors for good news or mild bad news firms, but positively correlated with
analysts’ forecast errors for extreme bad news firms; and 2) unconditional conservatism
reduces the overall uncertainty in analysts’ forecasts. The empirical results are
consistent with the predictions. Moreover, the evidence shows that the impact of
unconditional conservatism on analysts’ forecasts is greater for early forecasts, when
the information uncertainty is high, than for late forecasts.
