Although they may disagree about the exact nature of the opportunities for
profit confronting the potential entrepreneur, Kielbach, Audretsch, and Kirzner all
agree that entrepreneurship is caused by the ability of people to perceive and act
on these opportunities innovatively. If this idea is correct, then the level of
entrepreneurship in a given society is caused by both the extent to which
individuals in that society discern and utilize previously undetected opportunities
for profit and the levels of some of the traditional factors of economic growth
present in that society.
