Lecture 2 (continued) September 6, 2016 GAINS FROM TRADE MOVE BEYOND THE PPF (figure 2.5) Specialization and trade can move beyond the PPF: 1. Clearly show the level of consumption before trade on each PPF You Mary 8 lb apples 9lbs apples 12 lb cherries 2. Calculate the opportunity cost of each task for each producer You Mary Opportunity cos of picking apples 60 Cherries/ 30 Apples = 2 (#of Cherry) / (# of apple) = 30 apples/ 60 Cherries= 0.5 20Cherries/20apples =1 Opportunity cost of picking Cherries (# of apples)/(# of cherries)=20 cherries/20 apples= 1 3. Specialize in your comparative advantage: lower opportunity cost; Production Apple: You have a comparative advantage 1< 2 (20 Apples; 0 Cherries) Cherries: Mary has a comparative advantage 0.5 <1 (0 Apples; 60 Cherries) 4. Trade one good for another based on the given terms of trade (From the Textbook) Mary trades 15lbs of cherries for 10lbs of apples 5. Determine the level of consumption after trade(C.A.T.): check for gains from trade You Mary C.A.T. (20-10=10apples; C.A.T. (0+10=10apples; 60- 0+15=15cherries) 15=45cherries) G.F.T.(10-8=2apples; 15- G.F.T.(10-9=1apples; 45- 12=3cherries) 42=3cherries) Lecture 3 September 6,2016 THE LAW OF DEMAND: Ceteris paribus, when the pric)of a product fals), the quantity demanded (QD ) increases. This price change causes only a movement along the demand curve. (Warning) Graphical representation and negative slop(QD ) (Figure 3.1). Two effects at work behind the law of demand: Substitution: the fall in price causes to substitute away from other goods P Tab QD Smartphone, Laptop Income: the fall in price increases the consumer’s purchasing power PTablt Fixed Income= $1,000 PTab= $800 QD =1 PTab= $500 QD =2 “Feeling Richer PTab= $300 QD =3 Effect” Warning: a movement along the demand (price) vs. a shift in demand (other factors) Lecture 3 (continued) September 8,2016 What shifts the market demand? (Table 3.1) Income: From $1,000 to $1,500 Normal good: a rise in income → its demand shifts right Inferior good: a rise in income → its demand shifts left. o (Noodles) Fast food vs. Gourmet Food o Used Cars vs. New car Price of related goods: (A and B). Substitutes: the price of good B increases → the demand of good A increases o Ketchup vs. Mustard o IPhone vs. Galaxy o Coke vs. Pepsi o Powerade vs. Gatorade Galaxy Price changes, $600 →$650 The demand Galaxy decreases therefore the demand for iphones will increase Complements: the price of good B increases → the demand of good A decreases. o Chips and Salsa o P.B. and Jelly/Nutella o Pasta and Meatballs o Hot Dogs and Buns If Chips prices increase, the demand for chips will decrease. Since the chips price increase and the demand has decreased. The market for salsa has dropped Tastes and preferences (include demographics) If a product becomes more popular → its demand shifts right. o Ex. “Baby Boomers” o Population increased after WWII (late 40’s early 50’s) therefore they need more health care Expected future prices (the role of expectations) f buyers expect lower future prices → the current demand shifts left. o Ex. Tomorrow is “Black Friday” o Price for electronic will drop tomorrow therefore no one will demand electronics before “Black Friday” Lecture 3 (continued) September 8,2016
