quality of learning improves as the degree of environmental diversity to which an organ-
ization is exposed and the frequency of actions that are undertaken increase, but is also
subject to organizational constraints (Barkema and Vermeulen, 1998).
The organizational learning perspective has not been established as an important
explanation of corporate strategy, but it does provide an interesting direction for future
research. For example, it could help explain why single-business firms are less profitable
than related-diversified firms. Learning by single-business firms is limited, since they have
only a narrow pool of experiences to draw on. Moreover, the organizational learning per-
spective would predict that, for firms that have already diversified, further diversification
would be more feasible and successful than for firms that have no experience with diver-
sification at all. As a final example, it could help to understand why related acquisitions
are more successful than unrelated acquisitions (Bergh, 2001). Whereas the resource-
based view of the firm would relate this to the resources that can be transferred, the
organization learning perspective would point to the limited usefulness of a firm’s experi-
ences for unrelated activities. What is important to note, though, is that, according to
both the resource-based view and the organizational learning perspective, corporate
strategy and its success are highly firm specific, since they depend on, respectively,
accumulated resources and experiences, which are unique to every firm.
Strategic contingency theory
The final explanation of corporate strategy is provided by strategic contingency theory
(Venkatraman, 1989). The underlying notion is that a fit between a firm’s strategy, on the
one hand, and external and internal conditions or contingencies, on the other, increases
performance. Consequently, corporate strategy can be seen as a response to various
external and internal contingencies (Hoskisson and Hitt, 1990). Relevant external con-
tingencies are government policy and market failure. An important aspect of government
policy is anti-trust law. Through anti-trust law, policy-makers try to prevent large concen-
trations of power in an industry. If anti-trust policy is stringent and firms still want to
grow, they are forced to expand in a different industry and thus diversify. Market failure as
an incentive for diversification has already been discussed under transaction cost econ-
omics, above. If markets fail, coordination of activities in different industries within a firm
is more efficient. The firm then becomes diversified.
Examples of internal contingencies are low performance, uncertainty and risk reduc-
tion. If a firm performs weakly in an industry, it may flee to a different industry, in an
attempt to improve results. Similarly, uncertainty surrounding future cash flows that can
be earned in the current industry may drive a firm to a new industry. Finally, firms may
diversify into several industries in order to spread risks. As already explained under
agency theory, above, risk reduction is a suspicious reason for diversification in the eyes of
the shareholders. However, for other stakeholders, such as the managers, it may be a valid
incentive to diversify.
The previous examples of contingencies suggest that the distinction between
external and internal contingencies is not always clear-cut. For instance, the internal
contingency uncertainty may actually be induced by external demand conditions. Also,
the ability to exploit market failure depends on internal implementation mechanisms.
Furthermore, some of the contingencies have already appeared as part of other theories.
