For whom are the goods to be produced? The market economies What are the key elements of the market economy?  Freely determined price  Property rights and incentives  Competitive markets  Freedom to trade at home and abroad  A role for the Government  The role of NGOs  The optimum economic choice 2.1.People face trade- offs Make decisions: Compare cost with benefits of alternatives 2.2 Opportunity cost OC: Whatever must be given up to obtain one item  Tool for choice  Second model: The production possibilities frontier  Production possibilities frontier A graph  Combinations of output that the economy can possibly produce  Given the available  Factors of production  Production technology  25 The production possibilities frontier Quantity of Computers Produced C F 3,000 A 2,200 2,000 B Production Possibilities Frontier D 1,000 E 300 600 700 The production possibilities frontier shows the combinations of output - in this case, cars and computers - that the economy can possibly produce The economy can produce any combination on or inside the frontier Points outside the frontier are not feasible given the economy’s resources 1,000 Quantity of Cars Produced 26 Second model: The production possibilities frontier  Efficient levels of production Points on the PPF  Trade-off: The only way to get more of one good is to get less of the other good   Inefficient levels of production  Points inside PPF 27 Second model: The production possibilities frontier  Bowed out production possibilities frontier  Opportunity cost of one good= Give up the other good  Resource specialization 28 Second model: The production possibilities frontier  Technological advance Outward shift of the production possibilities frontier  Economic growth  Produce more of both goods  29 A shift in the production possibilities frontier Quantity of Computers Produced 4,000 3,000 G 2,300 2,200 A 600 650 A technological advance in the computer industry enables the economy to produce more computers for any given number of cars As a result, the production possibilities frontier shifts outward If the economy moves from point A to point G, then the production of both cars and computers increases 1,000 Quantity of Cars Produced 30 MATHEMATICS REVISION  Slope of the curve y 8 20 Slope= (28-20) = 2-1 x Revision (cont.)  Six types of relationship Increasin g positive slope Increasing negative slope Decreasin g Positive slope Decreasing negative slope Math revision (Cont.)  Constant slope Constant positive slope Constant negative slope Facts and impacts Movement along the curve vs shift of the curve  Movement along the curve: The line y shifts  When x and y changes when Z changes  Shift of the curve: Z2  When another variable z1 other than x and y change ⇒ A third variable shift the curve x  ...
