2.4. ANALYSES 47<br />

Table 2.15: Summary Statistics of Logit Regression Analysis<br />

Panel A - RPE-Use<br />

Correct classification (empty model) 53.1%<br />

Correct classification (full model) 61.2%<br />

Chi 2 = 25.8 (p = 0.011) Homer & Lemeshow p = 0.593<br />

Cox & Schnell R 2 = 0.090 Nagelkerke R 2 = 0.121<br />

Panel B - RPE-based-Targets<br />

Correct classification (empty model) 61.6%<br />

Correct classification (full model) 70.6%<br />

Chi 2 = 33.2 (p = 0.001) Homer & Lemeshow p = 0.390<br />

Cox & Schnell R 2 = 0.127 Nagelkerke R 2 = 0.172<br />

RPE-Use and RPE-Based-Targets support the first and second hypotheses, at the 10%<br />

level (one-tailed significance of the Wald statistic). These hypotheses refer to the effect<br />

of common uncertainty on RPE use, and the interaction effect of information asymmetry<br />

and comparability on RPE use, respectively. However, neither of the Logit analyses<br />

support the third hypothesis, which refers to the interaction effect of common uncertainty<br />

and information asymmetry on RPE use. Although these results are not entirely similar<br />

to the base model’s results, the findings substantiate the finding that both the noiseand<br />

opportunism-reduction perspectives on RPE, at least to some extent, help to clarify<br />

whether firms use RPE or not.<br />

2.4.4 Summary of the Findings<br />

The noise- and opportunism-based explanations of RPE use find (at least some) support<br />

in either one of the models. However, the primary (OLS and Tobit) analyses show only<br />

partially consistent findings for both operationalizations of RPE. Firstly, the positive effect<br />

of common uncertainty on RPE (H1) is robustly supported by all of the analyses.<br />

Secondly, I find only partial support for the hypothesized positive effect of the interaction<br />

between information asymmetry and comparability of the business unit (H2). Only the<br />

RPE-Use model supports this hypothesis. The opportunism mitigating characteristics of<br />

RPE (which is the underlying motivation for this hypothesis) may be more prevalent if<br />

RPE is not used for explicit performance target setting, but rather on the background of<br />

the performance evaluation. More generally, the marginal support for the opportunismreducing<br />

characteristics of RPE may be due to the limited use of external peer groups<br />

(as presented in section 4.1). Both internal and external peer groups may be relevant for<br />

noise-reduction, as both groups can be subject to similar noise-inducing external events.
