Exhibition: The argument
by Morck et al. [1988] Introduction: The hypothesis in the paper by Morck et al. [1988] is not based
on a formal model. Instead, they simply take the incentive alignment theory
and add it to a general entrenchment argument as illustrated in the figure
below. As shown in this figure the Morck et
al. argument does not predict a
‘clean’ bell-shaped relation between performance and ownership since
performance starts to increase again with a sufficiently high level of
ownership concentration. The reason for this prediction is that it fits the
empirical findings of their paper. Morck et
al.’s interpretation of their findings is that the entrenchment effect
will dominate the incentive effect only for medium concentrated levels of management
ownership. This is so because for low levels of managerial ownership it
might not be reasonable to think that the manager is entrenched at all since
his ownership stake is too small to give him any control whatsoever.
Furthermore, for very high levels of managerial ownership it seems
reasonable that the manager may be 100% entrenched since he will be 100% in
control for all very high levels of ownership. As a result, the entrenchment
effect will only have an impact on performance for changes in the
medium-concentration levels of ownership. |
