• Now a days we are using economy, economy.
• Each and every economy means reduction on
the cost (cost reduction economy).
• So where ever we want to purchase, we will
always think about reduction of cost this is
consumer point of view.
• Similarly in the organization point of view
economics means reduction of cost of
production and gaining maximum profits.
• Fighter consumer or organization always thinks
about profit in the business transaction.
• Profit=revenue- cost
• In order to gain profit we have to reduce eighter
cost or increase revenue.
• Revenue = no. units sold X selling price unit
• Cost = fixed cost + variable cost.
• So profit ‘P’ =( no. of units sold X selling price per
unit) __ (fixed cost + variable cost).
• In present competitive environment
increasing the revenue is difficult the only way
to gain maximum profit is reduction of cost.
• In the cost we cannot reduce fixed cost.
• It is possible to reduce only variable cost.
• All these kind of cost reduction techniques will

psychology and organization behavior.
• M.E. is the offshoot of economics and hence
the concepts of managerial economics is the
application of these in the real life.

problems, several empirically estimated functions
such as demand function, cost function, revenue
function and so on are extensively used.
• Economics and Managerial economics both are
concerned with the problems of scarcity and
• If the economist is concerned with study of
markets, the managerial economist is interested

tools and techniques of mathematics such as
algebra, calculus, exponentials, vectors inputoutput tables and such other .
• statistics deals with different techniques useful
to analyze the cause and effect relationships in a
given variable or phenomenon.
• It also empowers the manager to deal with the
situations of risk and uncertain through its
techniques such as probability .

techniques such as averages, measures of
series,interpolation,probability, and so on.

• The managerial economist profusely depends
upon accounting data for decision making and
• consumer psychology is the basis on which managerial
economist act upon.
• How the customer reacts to a given change in price or
supply and its consequential effect on demand/profits
is the main focus of study in managerial economics.

contributes towards understanding the behavior
implications, attitudes and motivations of each of the
microeconomic variables such as consumer,
supplier/seller. investor, worker or an employer.
