Business is influenced not only by what decisions are taken within the firm but also by the general business environment. General decisions are based on two factors : • External Factors : This includes all those factors which are outside the control of business. The firm can only make timely adjustment to these external factors. • Internal Factors : This includes all those factors which are within the control.

9. Consumer Behaviour
The theory of consumer s behavior seeks to explain the determination of
consumer s equilibrium. Consumer s equilibrium refers to a situation when
a consumer gets maximum satisfaction out of his given resources. A
consumer spends his money income on different goods and services in such
a manner as to derive maximum satisfaction. Once a consumer attains
equilibrium position, he would not like to deviate from it. Economic theory
has approached the problem of determination of consumer s equilibrium in
two different ways:
(1) Cardinal Utility Analysis
(2) Ordinal Utility Analysis

10. Utility Analysis or Cardinal Approach
• The Cardinal Approach to the theory of consumer behavior is based upon
the concept of utility. It assumes that utility is capable of measurement. It
can be added, subtracted, multiplied, and so on. According to this approach,
utility can be measured in cardinal numbers, like 1,2,3,4 etc. Fisher has
used the term Util as a measure of utility. Thus in terms of cardinal
approach it can be said that one gets from a cup of tea 5 utils, from a cup of
coffee 10 utils, and from a rasgulla 15 utils worth of utility.

11. Meaning of Utility
The term utility in Economics is used to denote that quality in a good or
service by virtue of which our wants are satisfied. In, other words
utility is defined as the want satisfying power of a commodity.
According to, Mrs. Robinson, Utility is the quality in commodities that
makes individuals want to buy them.

13. Utility
There are three concepts of utility
• Initial Utility
• Total Utility
• Marginal Utility

14. Relationship between total utility and Marginal Utility
The relationship between total utility and marginal utility can be
explained as:
• Total utility, initially, increases with the consumption of successive
units of a commodity. Ultimately, it begins to fall.
• Marginal Utility continuously diminishes.
• As long as marginal utility is more than zero or positive, total utility
increases, total utility is maximum when marginal utility is zero. It
falls when marginal utility is negative.
• When marginal utility is zero or total utility is maximum, a point of
saturation is obtained.

15. Indifference Curve Approach
• According to ferguson, An indifference curve is a combination of goods,
each of which yield the same level of total utility to which the consumer is
indifferent.
• According to leftwitch, A single indifference curve shows the different
combinations of X and y that yield equal satisfaction to the consumer.

17. Law of Demand And Elasticity Of Demand
• MEANING OF DEMAND - The term demand refers to a desire for
a commodity backed by ability and willingness to pay for it.
• LAW OF DEMAND - introduces an inverse relationship between
price and demand for a good or service. It simply states that as price
of a commodity increases, demand decreases, provided other factors
remain constant. Also, as prices decrease, demand increases

Production refers to the transformation of inputs or resources into
outputs of goods and services
Factors of Production
Inputs are the resources used in the production of goods and
services. As a convenient way to analysis, inputs are classified into
labour, capital, land and entrepreneur. Each of these broad
categories, however, includes a great variety of basic input.
