Pownall et al. (1993) document that nearly 80 percent of their sample
of voluntary management earnings forecasts are not precise point forec
asts. Imprecise forecast forms include closed-interval forecasts (i.e.
, ranges), open-interval forecasts (i.e., minimums and maximums), and
general impressions about firms' earnings prospects. We perform cross-
sectional logistic regressions to document determinants of forecast pr
ecision. Our sample consists of 1,212 annual and interim management fo
recasts. After controlling for firm-specific and horizon-specific earn
ings uncertainty, we find that managers produce more precise forecasts
of annual earnings for firms with greater analyst following (our prox
y for private information) and for smaller firms (our proxy for public
information). The results are robust across subsamples. The majority
of the results, however, do not hold for interim forecasts.
