According to Mansfield ,managerial economics is
applied microeconomics.
Whether profit or non-profit making organisations
and whatever may be their goals , they have all to
face constraints which may be internal & /or
external.
THE BASIC DECISION-MAKING PROCESS IS
SAME FOR ALL FIRMS.
All managerial decision problems are solved with
the help of tools ,concepts and principles in….a)
Economic theory; b) Managerial economics c)
Mathematical economics.
Role of economic theory---In any business, the businessman has to decide
what , how ,when ,how much , whom , where etc.
There arises question of choice at every stage of production.
eg. Choice regarding selection of project, location of plant
,inputs , funds etc.

The manager has to study environment at
Micro as well as Macro levels.
Micro economics here the subject-matter
is individual consumer ,firm market , industry
etc. Theories under micro-economics are
:Theory of value, theory of distribution,
theory of economic welfare etc.
Macro-economic environment is general
eco-pol-social condition of the larger system
which may be at domestic & /or international
level.
Role of mathematical economics
and econometrics---



Mathematical economics is used to
formalize economic laws. Eg. Law of
demand can be expressed mathematically
as Q =25 -3 (p) here demand is dependent
variable and price independent variable
;moreover demand is inversely related to
price.
Econometrics is application of statistics to
real world. Empirically collected data can be
applied to equations to find solution. eg.
Q= f (Y, Px , Py , W , U , T ,E ----- )
Trends revealed by forecasting help a firm
take optimal decisions.
Business environment and
managerial economics-



Business environment refers to all those forces
which influence functioning of business.
Two types of factors are relevant here-1)Internal
factors :these are controllable; either altered or
modified. 2) External factors- these are beyond
control
Example of internal factors: corporate philosophy,
physical assets , management structure, human
resources , R &D , FINANCE , technology etc.
Example of external factors :Customers , suppliers
, competitors , natural factors ,demographic
changes , political situation , eco-social condition ,
government policies etc.

Rationality
Many casual observers of the subject argue that
the relevance of the subject hinges on the selfish
nature of the humankind since it deals only with
satisfying the material desires. But economist
recognize that people act for variety of reasons,
some selfish some humanitarian. The point is that
the action of whichever type will be influenced by
the cost and benefit. As an activity becomes more
costly it is less likely to be chosen.
Person is likely to try to save the life of the boy
in three feet swimming pool rather than the rapid
current approaching Nigara Falls.
