WHAT IS MANAGERIAL ECONOMICS?
Managerial economics is the application
of economic theory and quantitative
methods (mathematics and statistics) to
the managerial decision-making process.
Simply stated, managerial economics is
applied microeconomics with special
emphasis on those topics of greatest
interest and importance to managers.
The role of managerial economics in the
decision-making process is illustrated in
Figure 1.1.
Definition: Managerial economics is the
synthesis of microeconomic theory and
quantitative methods to find optimal
solutions to managerial decision-making
problems.
To illustrate the scope of managerial
economics, consider the case the owner
of a company that produces a product.
The manner in which the firm owner goes
about his or her business will depend on
the company's organizational objectives.
Is the firm owner a profit maximizer, or is
management more concerned something
else, such as maximizing the company's
market share? What specific conditions
must be satisfied to optimally achieve
these objectives? Economic theory
attempts to identify the conditions that
need to be satisfied to achieve optimal
solutions to these and other
management decision problems.
As we will see, if the company's
organizational objective is profit
maximization then, according to
economic theory, the firm should
continue to produce widgets up to the
point at which the additional cost of
