5.1. SUMMARY, CONCLUSIONS AND DISCUSSION 119<br />

Despite the compelling theoretical basis of RPE, the literature is inconclusive with regard<br />

to the empirical validity of RPE. Whereas the analytical research has found strong evidence<br />

for RPE (Holmstrom 1982), the empirical literature has not generally reported substantive<br />

organizational reliance on RPE. Triggered by this puzzle, my dissertation research<br />

approaches RPE from a partially different angle. Whereas most prior studies have analysed<br />

RPE solely from a noise-reducing perspective, this thesis also explains RPE from an<br />

opportunism-mitigation viewpoint. In addition, whereas prior research has almost exclusively<br />

studied RPE by using archival data of RPE for executive compensation, the current<br />

research project uses in-depth survey data on RPE use within organizations at the level of<br />

business unit managers. The remainder of this section presents the findings of my thesis,<br />

organized into four topics. First, I discuss the prevalence of RPE amongst business unit<br />

managers. The second and third topic address the extent to which we can understand the<br />

use of RPE at this level with noise- and opportunism-reduction explanations. The final<br />

topic refers to the possibility of combining these explanations to further our understanding<br />

of RPE in practice.<br />

1. RPE use amongst business unit managers<br />

The first main finding of my research concerns the empirical puzzle presented earlier,<br />

which is that RPE seems to be theoretically and analytically sensible for business<br />

practice but lacks empirical support. The first topic that my thesis studies, is to<br />

what extent RPE is used for the performance evaluation of business unit managers.<br />

Overall, the body of RPE research on executive compensation suggests that RPE<br />

might not be widely used in practice. However, in chapter 2 of this dissertation, I<br />

report support for RPE use at the lower echelons of organizations. I find that RPE<br />

is widely used to evaluate business unit managers. More than half of the participants<br />

in my sample claim to use RPE to a large or very large extent. I observe that 88%<br />

of the business units in the sample use RPE to at least a small extent and that only<br />

approximately 8% of the respondents do not use RPE at all.<br />

The widespread organizational reliance on RPE seemingly contradicts the existing<br />

literature, which does not report large-scale RPE use. This difference is probably<br />

due to the level of analysis and type of data used for my research. My study focuses<br />

on the business unit level, where RPE may be more prevalent than at the executive<br />

level. Garvey & Milbourn (2003) argue that RPE may be inefficient if it is used<br />

to evaluate (relatively wealthy) executives because executives can more efficiently<br />

reduce noise in their incentive contracts by directly adjusting their own private investment<br />

portfolios. However, personal hedging is likely to be too costly for less<br />

wealthy employees. These high costs of hedging may increase the attractiveness of<br />

RPE to people working at the lower echelons, such as business unit managers.
