Elasticity of Demand

Elasticity of Demand: 
Tells how drastically buyers will cut back or increase their demand for a good when the prices rise or fall.

Elastic Demand - When demand will change greatly given a small change in price Wants (ticket prices for movies increase then we are lead to find alternative ways) More than one

Inelastic Demand - Your demand for a product will not change regardless of price Needs(gasoline, salt, medicine) Less than one 

Uni elastic Demand - Equal to one

  1. New quantity - old quantity/old quantity
  2. New price - old price/old price
  3. PED
Equilibrium: 
The point at which the supply curve and demand curve intersect. This point they meet at shows that the resources are being used efficiently.

Shortage - QD>QS

Surplus - QS>QD

Price Ceiling:
Government imposed limit on how high you can be charged. 
Price Floor:
Government price control on how low a price can be charged for a product.
Total Revenue - Price x Quantity

Marginal Revenue - Additional income from selling an additional unit of a good
 


Fixed Cost - A cost that does not change no matter how much is produced (rent, mortgage)

Variable Cost - cost that changes and fluctuates (water bill - how much you use)

Marginal Cost - New total cost - old total cost spend the cost, revenue is what you bring in

Total CostTFC + TVC = TC

Average Total Fixed Cost - AFC + AVC

Average Fixed CostTFC/Quantity

Average Variable CostTVC/Quantity

Total Variable Cost Quantity x AVC
