We propose a novel method to forecast corporate earnings which combines the accuracy of analysts' forecasts with the unbiasedness of a mechanical model. Our choice of variables is driven by recent insights from the earnings forecasts literature and the resulting model outperforms all analyzed methods in terms of accuracy, bias, and earnings respons...

... order to analyze forecast bias over time, Figures 1 to 6 show the mean and median forecast bias for one-, two-, and three-year-ahead earnings forecasts. For the sake of clarity, we only include the raw analysts' forecasts, the combined model, and the benchmark model with forecast bias closest to zero in the figure. ...

Biases impair the effectiveness of algorithms. For example, the age bias of the widely-used PageRank algorithm impairs its ability to effectively rank nodes in growing networks. PageRank’s temporal bias cannot be fully explained by existing analytic results that predict a linear relation between the expected PageRank score and the indegree of a giv...

In this paper, we propose a chain ratio-product type estimator of population total in two phase sampling when information on two auxiliary characters is available in different phases. It is assumed that complete information is available for one auxiliary variable while information is not available for other auxiliary variable and the double samplin...

The measure obtained from the Implicit Association Test (IAT; Greenwald et al., 1998. DOI: 10.1037/0022-3514.74.6.1464) is often used to predict people’s behaviors. However, it has shown poor predictive ability potentially because of its typical scoring method (the D score), which is affected by the across-trial variability in the IAT data and migh...

This study updates and expands upon the existing work on the accuracy of the IPF’s Consensus Forecasts. The paper evaluates the extent to which the consensus forecasts were able to predict the relative performance. It also assesses the accuracy of implied yield forecasts and concludes that failure in yield forecasting is the main source of failure...

The polychoric instrumental variable (PIV) approach is a recently proposed method to fit a confirmatory factor analysis model with ordinal data. In this paper, we first examine the small-sample properties of the specification tests for testing the validity of instrumental variables (IVs). Second, we investigate the effects of using different number...

... Recently, earnings forecasts based on a cross-sectional model, which only requires firms' fundamental features such as accounting numbers, have emerged as an alternative method (Hou, van Dijk, & Zhang, 2012: hereafter HVZ). This method is widely applied to exploring the mean reversion characteristics of earnings (Fama & French, 2000), estimating the implied cost of capital (HVZ; Li & Mohanram, 2014), detecting market overreactions to analyst forecasts (So, 2013), and improving forecasts in connection with the differential persistence of earnings components (Call, Hewitt, Shevlin, & Yohn, 2016) or past analyst forecasts (Azevedo, Bielstein, & Gerhart, 2020). ...
