measure environmental uncertainty with one multi-item construct. The measure for environmental<br />
uncertainty is calculated as the mean of the six items 16 .<br />

However, by measuring environmental uncertainty, I measure both common uncertainty<br />
and idiosyncratic uncertainty. Therefore, the idiosyncratic part has to be filtered out of<br />
the uncertainty measure. To separate common from idiosyncratic uncertainty, I use information<br />
about how common the business unit is, compared to its peers. The logic behind<br />
this is the following: consider a very unique business unit, with assets that none of its peers<br />
has. For example, it has highly specific equipment, a high-profile brand image, and/or a<br />
highly diversified client portfolio, non of which its peers have. If an external event occurs<br />
that affects performance, it is likely that this event affects only this business unit and does<br />
not influence its peers, because its peers use different assets that affect performance in a<br />
likely different manner. Vice versa, if a highly comparable business unit, using common<br />
assets, faces external influences that affect its performance, it is likely that, besides the<br />
own performance also the performance of peers (who operate in more-or-less similar ways,<br />
using more-or-less similar assets) is affected by the event.<br />
To measure how common the business unit is compared to other business units inside<br />
or outside of the firm, I develop a measure labelled ‘comparability of the business unit’.<br />
Comparability of the business unit is discussed in the next section.<br />
16 Before calculating the mean score, 7-point scales are recoded to 5-point Likert scales, to prevent<br />
overrepresentation of the 7-point scaled items in the uncertainty construct.
