Product markets are weaker in some nations than they are in others. Weaker
product markets, and the concomitant monopoly rents, can affect corporate g
overnance. They can do so directly by loosening a constraint on managers, t
hereby increasing managerial agency costs to shareholders-costs that shareh
olders would then seek to reduce otherwise. The monopoly profits can also a
ffect corporate governance structures indirectly by setting up a fertile fi
eld for conflict inside the firm as the corporate players-shareholders, man
agers, and employees-seek to grab those monopoly profits for themselves. On
e would expect corporate governance structures, laws, and practices in nati
ons with monopoly-induced high agency costs to differ from those prevailing
in nations with more competition, fewer monopolies, and lower agency costs
. And we might speculate that these rents when large and widespread could a
ffect democratic politics and law-making: directly by making monopolists po
litical targets (and political forces); and indirectly as the players insid
e the firm seek to capture those monopoly profits through political action,
with political parties and ideologies (and, in time, laws and standards) t
hat parallel the players' places inside the firm. Data from the industrial
organization, finance economics, and political science literature is consis
tent.
