What is microeconomics Microeconomics is branch of
economics that studies the behaviour of businesses and how decisions are made based on the allocation of limited resources.

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

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

How to calculate consumer surplusSLICE 1 2 3 4 5 6
WTP 6 Rs 5 Rs 4 Rs 3 Rs 2 Rs 1 Rs
P* = 3 , Q = 4 CS = (6-3)+(5-3)+(4-3)+(3-3) CS = 6 Rs
P* = 2 , Q = 5CS = (6-2)+(5-2)+(4-2)+(3-2)+(2-2)CS = 10 Rs

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.

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.

• The causes of increasing return of scale
1.Technical and managerial indivisibilities
2. Higher degree of specialization3. Dimensional relations

• When firm increases the inputs proportionately there are three possibilites
1. total output may increase more than proportionately2. total output may increase proportionately3. total output may increase less than proportionately
Accordingly there are three kind of return of scale
1. Increasing return of scale2. decreasing return of scale 3. constant return of scale

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

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.

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

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.

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
