11. Difference between Managerial Economics and
Economics
Economics
1.Comprehensive and wider
scope
2.It has both Micro and Macro in
nature
3.It is both Normative and
positive science
4.It is concerned with the
formulation of theories and
principles
5.It discusses general problems
Managerial Economics
1.Narrow and limited scope
2.It is essentially Micro in nature
and Macro in analysis
3.It is mainly a Normative science
4.It is concerned with the
application of theories and
principles of economics
5.It discusses Individual problems
12. Nature of Managerial Economics
ď Science as well as Art of decision making.
ď It is essentially Micro in nature but Macro in
analysis.
ď It is mainly a Normative science but positive in
analysis.
ď It is concerned with the application of theories and
principles of economics.
ď It discusses Individual problems.
ď It is dynamic in nature not a Static.
ď It discuss the economic behavior of a firm.
ď It concentrates on optimum utilization of resources.
13. Scope of Managerial Economics
ďObjectives of a Firm.
ďDemand Analysis and Forecasting.
ďProduction and cost analysis.
ďPricing decisions.
ďProfit management.
ďCapital management.
ďMarket structure.
ďInflation and economic conditions.
14. Managerial economics and Decision
Making
⢠Decision making:
â Decision making on internal affairs.
â Decision making on external affairs.
Internal affairs talk on internal environment which
consists of internal factors such as, Production,
Financial, Marketing and Human resource related
decisions.
External Affairs talk on external environment
which consists of external factors such as, PEST
related decisions.
15. Decision Making
⢠Uncertainty:
â Nothing can be expectable because of the
constant changes in the environment both
internally as well as externally.
⢠Risk:
â It is the situation which comes under uncertainty.
17. Economic Models
Economic model
is the structural and scientific method of
constructing or developing Solutions by
using basic economic principles,
concepts, theories and Quantitative
techniques such as mathematical and
statistical tools.
18. Steps to construct
Economic M
odels
Defining the
problem
Formulation of
hypothesis
Data collection
Analysis of data using Basic Principles
of economics and Quantitative
Techniques.
Evaluating results
Testing of
Hypothesis
Conclusion for
decisions.
19. Basic Principles of Managerial
Economics
Opportunity cost principle.
Marginalism principle.
Equi-marginalism principle.
Incremental principle.
Time perspective principle.
Discounting principle.
20. Opportunity Cost Principle
Choice involves sacrifice.
The cost involved with the sacrifice
It is the cost of an next best opportunity which
is lost will be called as Opportunity cost.
Ex: 100 Rs can be used for purchasing book or
eating in pizza corner or purchasing of
stationeries.
Now the cost of purchasing book is also include
the cost of âEating pizza.â
21. Opportunity Cost in Management

22. Marginalism Principle
Marginal cost
and
Marginal profit/benefit
Marginal cost is the cost which incurred to
produce the next or one more unit.
Marginal Revenue is the benefit which gets by
producing one more or next unit.
Cost will be less and benefit will be more.
24. Equi-marginalism Principle
⢠Allocation of scarce resources on different
alternative uses should be equally distributed.
i.e.. MPa = MPb =MPc =MPd
Or
MPa = MPb = MPc = MPd
COPa COPb COPc COPd.
25. Incremental Principle
⢠Incremental principle gives an idea to increase
the production not only with one more
product it could be any quantity till the profit
exists.
⢠According to this principle profit can be
existed either by increasing sales or total
revenue or by decreasing total cost
⢠Decision Rule,
⢠i.e. TC<TRâŚâŚTC=TRâŚâŚTC>TR
26. Time Perspective Principle
⢠According to the principle all decisions should
be under two formats i.e. short run and long
run, Because of the decisions characteristics.
⢠So each decision should be made in Short run
basis as well as long run basis.
⢠According to short run decision the long run
decision will get change.
27. 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. This is essential because a rupee
worth of money at a future date is not worth a
rupee today. Money actually has time value.
28. Discounting Principle
⢠This could be understood using the formula,
FV = PV*(1+r) t And
PV = FV/ (1+r) t
⢠Where, FV is the future value, PV is the
present value, r is the discount (interest) rate,
and t is the time between the future value and
present value.
