In the citing paper
“For example, Caudill and Ford (1993) provide evidence on the bias of the estimated technological parameters, but not on the efficiency levels themselves or their relationship to the explanatory variables z.”
From One-Step and Two-Step Estimation of the Effects of Exogenous Variables on Technical Efficiency Levels (2002) · cites this paper as Caudill and Ford (1993)
In the citing paper
“It is widely agreed that the first step of the two-step procedure is biased if x and z are correlated.”
From One-Step and Two-Step Estimation of the Effects of Exogenous Variables on Technical Efficiency Levels (2002) · cites this paper as Caudill and Ford (1993)
In the citing paper
“It has long been recognized that such a two-step procedure will give biased results, because the model estimated at the first step is misspecified.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
