  1. TOPICS COVERED <ul><li>Demand </li></ul><ul><li>Law of Demand </li></ul><ul><li>Law of Supply </li></ul><ul><li>Equilibrium </li></ul><ul><li>Shortage and Surplus </li></ul><ul><li>Shift in Demand Curve </li></ul><ul><li>Shift in Supply Curve </li></ul><ul><li>Case Study of Tax Incidence </li></ul><ul><li>Live Example </li></ul>
  2. DEMAND <ul><li>THE PERSON IN THE CAR NEED PETROL </li></ul><ul><li>THE PERSON HAS PUURCHASING POWER </li></ul><ul><li>THE PERSON HAS WILLINGNESS TO PAY </li></ul>IF ALL 3 THINGS ARE THERE THEN PETROL IS THE DEMAND OF THAT PERSON.
  3. Law of Demand <ul><li>law of demand states that as price falls, demand extends and as price rises, demand contracts, other things being equal. </li></ul><ul><li>other things being equal means that all factors other than price influencing the demand are assumed constant(no change) like prices of related goods, income of consumer, future expectations regarding price and income etc. </li></ul>
  4. Curve of Law of Demand PRICE QUANTITY 5 10 4 20 3 30 2 40 1 50
  5. Law of Supply <ul><li>law of supply states that as price rises, supply rises and as price falls, supply falls, other things being equal. </li></ul><ul><li>other things being equal means that all factors other than price influencing supply are assumed as constant(no change) like prices of factors of production, goal of the firm, govt. policy, future expectations regarding price etc. </li></ul>
  6. Curve of Law of Supply PRICE QUANTITY 5 50 4 40 3 30 2 20 1 10
  7. Equilibrium:- <ul><li>In economics, an  equilibrium  is a situation in which: </li></ul><ul><li>quantity demanded equals quantity supplied. </li></ul><ul><li>refers to a condition where a market price is established through competition such that the amount of goods or services sought by buyers is equal to the amount of goods or services produced by sellers. </li></ul>
  8. Curve of Equilibrium PRICE QUANTITY DEMANDED QUANTITY SUPPLIED 5 10 50 4 20 40 3 30 30 2 40 20 1 50 10
  9. Shortage and Surplus <ul><li>A shortage occurs when quantity demanded exceeds quantity supplied. </li></ul><ul><ul><li>A shortage implies the market price is too low. </li></ul></ul><ul><li>A surplus occurs when quantity supplied exceeds quantity demanded. </li></ul><ul><ul><li>A surplus implies the market price is too high. </li></ul></ul>
  10. Shift in the Demand Curve <ul><li>A change in any variable other than price that influences quantity demanded produces a shift in the demand curve or a change in demand. </li></ul><ul><li>Factors that shift the demand curve include: </li></ul><ul><ul><li>Change in consumer incomes </li></ul></ul><ul><ul><li>Population change </li></ul></ul><ul><ul><li>Consumer preferences </li></ul></ul>
  11. Shift in Demand curve
  12. Equilibrium After a Demand Shift
  13. Shift in Supply Curve <ul><li>A change in any variable other than price that influences quantity supplied produces a shift in the supply curve or a change in supply. </li></ul><ul><li>Factors that shift the supply curve include: </li></ul><ul><ul><li>Change in input costs </li></ul></ul><ul><ul><li>Increase in technology </li></ul></ul>
  14. Shift in Supply Curve
  15. Equilibrium After a Supply Shift
  16. CASE STUDY <ul><li>TAX INCIDENCE:- </li></ul><ul><li>As one example of demand and supply analysis, let us assume we have a product with the situation shown in the graph below. The price is $1.00 per unit. </li></ul><ul><li>  </li></ul>
  17. Continued…. <ul><li>Now a sales tax is imposed. The tax is charged to the seller. For every $1.00 of sales, assume that the seller must pay $0.07 to the government. (Notice that consumers do not pay sales taxes. You have not paid any sales tax money to any government agency. The store pays the sales tax to the government.) </li></ul><ul><li>From the point of view of the seller, this is an additional cost of production. In addition to all other costs, the seller must also pay the sales tax. </li></ul><ul><li>Do costs of production affect demand or supply? </li></ul><ul><li>Will there be a shift or movement along supply? </li></ul><ul><li>Since the change is caused by something other than the price of the product, the answer is a shift. </li></ul><ul><li>Since costs of production are increasing, the good is less profitable, causing supply to decrease. </li></ul>
  18. Continued….. <ul><li>we can say that the seller would like to, raise the price to $1.07. Then, the seller could pay the $0.07 in tax and still have the same $1.00 that was earned before the sales tax was imposed. </li></ul><ul><li>However, due to the law of demand, the seller cannot raise the price to $1.07. If the seller raises the price, the quantity demanded will fall. </li></ul><ul><li>In this case, equilibrium occurs with the new price at $1.04. At any higher price, there would be a surplus. We say that $0.04 is the incidence of the tax on the buyer because the buyer must pay a $0.04 higher price. </li></ul><ul><li>We say that the other $0.03 is the incidence of the tax on the seller because the seller earns $0.03 less that was earned before the sales tax was imposed ($1.04 - $0.07 = $0.97). </li></ul>

  20. LIVE EXAMPLE:- <ul><li>The heat of oil prices was strongly felt as the oil prices reached $50 per barrel in early 2005 from $10 per barrel in 1998. </li></ul><ul><li>The prices were driven by the surge in demand in countries that included US, India and China and also the supply factors that had failed to meet the rise in demand. </li></ul>
  21. EFFORTS OF:- <ul><li>HERSHUL VIRENDRA </li></ul><ul><li>KAMAL GOVIL </li></ul><ul><li>SNEHA SUNDRANI </li></ul><ul><li>SHYAM AGRAWAL </li></ul><ul><li>DEEPIKA PRABHAKAR </li></ul><ul><li>RAJAT GUPTA </li></ul>
