At some point, hiring managers in all organizations face the decision of whether to fill open positions
with internal candidates (e.g., through promotions) or to hire external candidates (e.g., from competitors
or new entrants into the labor market). Despite this ubiquitous choice, surprisingly little research has
compared the effectiveness of internal and external selection or has identified situations in which 1
approach may be better than the other. The authors use theory on human capital resources to predict
differences between internal and external hires on manager- and unit-level outcomes. Analysis of data
from a quick-service retail organization (N⫽3,697) suggested that internally hired managers demon-
strated higher levels of individual job performance and commanded lower starting salaries than externally
hired managers. At the unit-level, operations led by internal hires demonstrated higher performance on
organization-specific criteria (i.e., service performance), whereas no internal– external differences were
found on more general criteria (i.e., financial performance). They also found some evidence that
differences in unit service performance decreased over time (but did not diminish completely) as external
hires improved at a slightly faster rate than internal hires. Overall, these findings underscore the
complexity of the recurring “build or buy” decision. The results also suggest that internal hires generally
outperform external hires, both individually and collectively, and they do so for less money.

The effective use of human capital is a critical determinant of
organizational performance and competitive advantage (Nyberg,
Moliterno, Hale, & Lepak, 2014;Ployhart, Nyberg, Reilly, &
Maltarich, 2014). Staffing serves as one of the most important
human resource functions because it represents the primary means
by which organizations attract and acquire human capital (Ploy-
hart, 2006). Staffing involves numerous decisions, including how
to recruit potentially qualified applicants, how to assess whether
applicants possess the necessary qualifications, and, ultimately,
how to determine which candidates to select.
One of the most fundamental staffing decisions organizations
must make is whether to fill job openings through internal selec-
tion or external selection. Internal hires are workers who already
are members of an organization and (a) were selected into a
higher-level position from a lower-level position (i.e., an internal
promotion) or (b) were selected into the same or a similar position
from a different part of the organization (i.e., a lateral transfer). In
contrast, external hires are selected from outside the organization
and include individuals (a) who previously were employed by
another organization, (b) who previously were unemployed, or (c)
who were entering the labor market for the first time (e.g., recent
graduates).
Each of these two approaches to selection possesses potential
benefits and challenges. For example, internal candidates know the
organization’s culture, routines, and processes and have estab-
lished relationships with other current members. As such, internal
hires may “get up to speed” in their new role more quickly than
external hires (Krell, 2015). Further, an emphasis on promotion
from within may increase employees’ commitment to the organi-
zation (Mathieu & Zajac, 1990). On the other hand, although
selecting an internal candidate fills one open position, the position
the transferred or promoted employee came from now is open.
Thus, whereas one human capital need has been solved, another
has been created. Also, if multiple internal candidates apply for a
single job opening, candidates who were not selected may become
dissatisfied and engage in counterproductive behaviors, such as
reducing their effort or withdrawing from the organization (Spec-
