Introduction to Managerial Economics
Economic principles assist in rational
reasoning and defined thinking. They
develop logical ability and strength of a
manager.
The Important principles of managerial
economics are:
? Incremental Principle
? Equi-marginal Principle
? Opportunity Cost Principle
? Time Perspective Principle
? Discounting Principle
Incremental Principle
This principle states that a decision is
said to be rational and sound if given the
firm’s objective of profit maximization, it
leads to increase in profit, which is in
either of two scenarios-
? If total revenue increases more than total
cost
? If total revenue declines less than total
cost
Incremental cash-flow principle
Project financing concept that the
only cash flows relevant to the
valuation of a project are the
incremental cash flows resulting
from it
Equi-marginal Principle
The laws of equi-marginal utility states
that a consumer will reach the stage of
equilibrium when the marginal utilities of
various commodities he consumes are
equal.
The law of Equi-marginal utility
According to the modern economists, this
law has been formulated in form of law of
proportional marginal utility. It states that
the consumer will spend his money-
income on different goods in such a way
that the marginal utility of each good is
proportional to its price, i.e.,
Opportunity Cost Principle
Opportunity cost is one of the most
important and fundamental concepts in
the whole of economics. Given that we
have said that economics could be
described as a science of choice, we
have to look at what sacrifices we make
when we have to make a choice. That is
what opportunity cost is all about.
Sacrifice of Alternatives
? Opportunity cost is the minimum price
that would be necessary to retain a
factor-service in it’s given use. It is also
defined as the cost of sacrificed
alternatives
? By opportunity cost of a decision is
meant the sacrifice of alternatives
required by that decision
Time Perspective Principle
According to this principle, a manger
should give due emphasis, both to short-
term and long-term impact of his
decisions, giving apt significance to the
different time periods before reaching
any decision
Time periods
? Short-run refers to a
time period in which
some factors are
fixed while others are
variable. The
production can be
increased by
increasing the
quantity of variable
factors
? long-run is a time
period in which all
factors of production
can become variable.
Entry and exit of
seller firms can take
place easily
Discounting Principle
According to this principle, if a decision
affects costs and revenues in long-run,
all those costs and revenues must be
discounted to present values before valid
comparison of alternatives is possible
Discounting
? Discounting can be defined as a process
used to transform future rupees into an
equivalent number of present rupees.
? This is essential because a rupee worth
of money at a future date is not worth a
rupee today. Money actually has time
value. For instance, Rs.100 invested
today at 10% interest is equivalent to
Rs.110 next year.
