This document is a presentation by Hemant Meena on microeconomics concepts. It discusses consumer surplus, willingness to pay, how to calculate consumer surplus. It also covers the three types of returns to scale: increasing, decreasing, and constant returns to scale. Examples are given for each type of returns to scale. The law of returns and diminishing returns are explained with a historical example of firebombing in war. Graphs are included to illustrate the concepts discussed.

4. What is consumer surpuls
it is the difference between the total
amount that consumer willing and able
to pay for goods and service and the
total amount that we actually do pay .
i.e. the market price

5. What is Willing to pay(WTP)
The maximum amount that we able
to pay. it is also known as reservation
price.

7. Why are economists interested in the
consumer surplus?
Economists are interested in consumer
surplus because it measure economic welfare,
plays a large part in changing market prices,
plays a role in the price elasticity of demand
and allows for price discrimination.

8. The return of scale
It explains the rate of increase in output
relative to increase in input.While
economiecs of scale show the effect of an
increased output level on unit costs,
returns to scale focus only on the relation
between input and output quantities.

9. The causes of increasing return of
scale
1.Technical and managerial
indivisibilities
2. Higher degree of specialization
3. Dimensional relations

10. When firm increases the inputs proportionately
there are three possibilites
1. total output may increase more than proportionately
2. total output may increase proportionately
3. total output may increase less than proportionately
Accordingly there are three kind of return of
scale
1. Increasing return of scale
2. decreasing return of scale
3. constant return of scale

11. Increasing Returns of Scale
Increasing returns of scale occurs
when a firm increases its inputs,
and a more-than-proportionate
increase in production results.

12. Decreasing return of scale
Decreasing returns of scale is closely
associated with diseconomics of
scale.Decreasing returns of scale
happens when the firm's output rises
proportionately less than its inputs
rise.

13. Constant return of scale
When the change in input is
proportional to the change in
output.it exhibits constant return
of scale

14. Law of return
If the factor of production is
increased, there comes a point
where it will become less productive
and therefore there will eventually
be a decreasing.

17. Historical example
In the war of America and
Japan , America is use
firebombing and reduce
numbers of soldiers . This uses
law of diminish of return
