The Role of Economics in
Management Decision Making
Managers must observe and predict what will
happen in the overall economy to ensure that
their decisions match their best guesses of the
future.
Large publicly held companies in particular must
look at the economy because they know their
performance and stock price will be affected by
forces beyond their control.

The Role of Economics in
Management Decision Making
Stockholders will want to see continually rising
stock prices or at least valid reasoning if stock
prices do not meet expectations.
Top managers in these large companies may
make acquisitions, sell divisions, or even sell the
company itself depending on their assessment
of the economy and how their firm can compete.
