122 CHAPTER 5. CONCLUSION<br />

addresses the RPE claim in a more direct manner than chapter 2. The models in<br />

chapters 3 and 4 focus on testing a single explanation instead of including both perspectives<br />

simultaneously. The benefit of the analyses in chapters 3 and 4 lies in their<br />

statistical power. The analyses are statistically more powerful because they do not<br />

include or require statistically demanding interaction effects. Increasing statistical<br />

power is especially important for the opportunism perspective because limited statistical<br />

power could have driven the marginal findings in chapter 2.<br />

However, chapter 4 confirms the conclusions of chapter 2 with regard to the opportunism-mitigating<br />

properties of RPE. Similar to chapter 2, the analyses in chapter<br />

4 show that RPE has no opportunism-mitigating effect for business unit managers.<br />

Instead, the analyses of chapter 4 indicate that using RPE increases (instead of decreases)<br />

the room that managers have to behave opportunistically.<br />

A partial, post-hoc explanation for why RPE does not reduce the room for managerial<br />

opportunism is found in the work of Davila & Penalva (2006) and Ittner et al.<br />

(1997). According to Davila & Penalva, managers can influence the composition and<br />

weighting of their own performance measurement system. Managers self-select a set<br />

of performance targets that is highly controllable. Ittner et al. argue that managers<br />

may influence the composition of their PMS to obtain more manipulable performance<br />

measures. If managers can influence their performance measurement system, they<br />

can also influence their performance standard. Thus, managers can choose those<br />

measures on which they compare favourably with their peers. By self-selecting the<br />

performance metrics (or the weight placed on the individual metrics in the performance<br />

measurement system), the manager bypasses the opportunism-mitigating<br />

properties of RPE. My data support this observation by Ittner et al. (1997). In<br />

response to a question not used earlier in this study, my respondents claim that they<br />

can negotiate or otherwise influence their performance criteria to, on average, some<br />

extent. Moreover, this influence increases with increasing use of RPE for explicit target<br />

setting purposes. My data show no association between less specific applications<br />

of RPE and the possibility to influence the set of performance criteria.<br />

Although this explanation reasons why RPE may not be an efficient control instrument<br />

for opportunism reduction, it only partially explains the positive effect of RPE<br />

on the room for managerial opportunism. From the analyses in chapter 2, we learn<br />

that organizations implement RPE into the performance evaluation praxis of business<br />

unit managers mainly by relying on internal and mixed peer groups. Within<br />

my sample, only 8% of the RPE users rely exclusively on external peers, whereas<br />

the remaining 92% use internal peers at least to some extent to determine the performance<br />

targets. However, using internal peers may violate Murphy’s (2001) ‘influenceability’<br />

presumption. The reason why RPE may reduce opportunism because
