 Operating period in which at least one factor of production is
in fixed supply
 Long Run
 Operating period in which all factors of production are in
variable supply
 Short Run Profits Vs Long Run Success of Business

Econometrics
 Relationship to economic theory:
 Linked to individual firms investment decision,

 Macroeconomic conditions in which a firm is
functioning.
 Economic theories aim to predict economic behaviour
 Theory of the firm is of utmost importance for
Managerial Economics

 Mathematical Economics is used to formalize the
economic models of economic theory in the form of an
equation
 Econometric tools are used to statistically analysis the
models using real world data
 The tools are used for forecasting as well.
 For Example: Demand of Education
Relationship to Decision Sciences

 y=f(x) or y=g(x,z) or y=h(x1, x2,…..xn)
 Total, Average and Marginal Products
 Example: Labor to be employed in Construction

experiments by holding everything else constant
Functional Relationships in Economics

 Example of Demand and Supply
 Demand Function
Qd=a-bP where b<0
 Supply Function
Qs=c+dP where d>0
