Title: TOPIC 2 URL Source: file://pdf.d516443ffb55a6bc500ebc219e1a593b/ Markdown Content: > TOPIC 2 ## ECONOMIC PROBLEMS ## & PRODUCTION POSSIBILITY ## FRONTIER CONTENTS relationship between the production possibilities frontier (PPF) and economic problems - scarcity, choice, and opportunity cost . the shapes of the production possibilities frontier factors that shift the PPF curve . Application of PPF curve : > single country/firm > International trade INTRODUCTON All decision in economy constrained by the scarcity of available resources Because resources scarce, all economy decision involve trade -off -- if u need one thing you have give up another thing . Scarcity of resources means resources are always limited necessity of choices (recall topic 1)INTRODUCTON ## Because physical resources are limited we ## have to make some hard choices . ## More of one output less of the other ## output . ## Eg : If we use many resources in the ## production of car then we have cut back ## another production let say refrigerator .PRODUCTION POSSIBILITY > FRONTIER (PPF) PPF is used to explain three fundamentals problem in economics scarcity, choice and opportunity cost . For instance, each country needs to allocate its limited resources to produce goods across various industries such as education, healthcare, food, infrastructue etc . Hence, countries must make choices about which goods to produce and which goods to forgo .DEFINITION OF PPF Production possibilities frontier a curve that depicts maximum combinations of two goods that can be produced by the country using all available resources at a specific technological level PPF = a graph showing different combinations of output for a given amount of inputs > More of one good less of another > Illustrates opportunity costs in production ## PPF : ASSUMPTION Assumptions for the formation of the production possibilities frontier : The country only produces 2 types of goods The production factors are fixed and the country use all the available resources The technological level are fixed Full utilization of resources PRODUCTION POSSIBILITY FRONTIER : TABLE Combination Health (Y) Education (X) A 21 0 B 20 1 C 18 2 D 15 3 E 11 4 F 6 5 G 0 6 > Table 2.1 : Production of Health and Education PRODUCTION POSSIBILITY FRONTIER : GRAPH > A > B > C > D > E > F > G > 0 > 2 > 4 > 6 > 8 > 10 > 12 > 14 > 16 > 18 > 20 > 22 > 24 > 01234567 > Health Education The production possibilities frontier slopes downward to the right PPF & ECONOMICS PROBLEMS SCARCITY Along the PPF curve when increase the production of education need to decrease the production of health . CHOICE Movement from point to point along the PPF curve trade -off occur Move from A to B At A if the country used all the resources to produce health then the production of health is zero At point B - if the country want to produce both - need to decrease the production of health to increase the production of education OPPORTUNITY COST Negatively sloped ; the slope = opportunity cost From A to B - to increase 1 unit of education need to decreased 1 unit health PPF : CALCULATION OF OPPORTUNITY COST Point Movement Raduction in Health ( ) Increase in education ( ) Opportunity Cost X ( ) 20 21 = 1 1 0 = 1 1/1 = 1 18 20 = 2 2 1 = 1 2/1 = 2 15 18 = 3 3 2 = 1 3/1 = 3 11 15 = 4 4 3 = 1 4/1 = 4 6 11 = 5 5 4 = 1 5/1 = 5 0 6 = 6 6 5 = 1 6/1 = 6 Increasing opportunity cost due to an imperfect substitute input. Implication: The shape of PPF curve is convex from the origin THE SLOPE OF PPF The slope of PPF = Marginal rate of transformation (MRT) Formula: = MRT XY measures the opportunity cost of producing the good at X axis (horizontal axis) which is education (refer to the example) .THE SHAPE OF PPF The shape of PPF determined by the type of opportunity cost. Constant opportunity cost - PPF with straight line due to perfect substitute input Decreasing opportunity cost PPF concave to the origin Specialization in production process reduce average cost benefit from economies of scale.

SHIFT IN PPF Assumption: Education is labor intensive Health is capital intensive SHIFT IN PPF Assumption: Technological Advancement PPF: APPLICATION PPF can be used to explain the benefits of specialization when a country is involved in international trade. Absolute advantage the ability to produce a good more efficiently than others. Comparative advantage the ability to produce a good at a lower opportunity cost/relative price compared to others. ABSOLUTE ADVANTAGE Absolute advantage is a concept that measures a country's production capacity by comparing labor productivity between countries. Assumption: 2 countries, A & B producing cloth and food. Input used is labor with different productivity (see table) Labour cost = RM10/hour Each country has 1000 hours of labor > Clothes (X) Food (Y) > Country A 22 > Country B 41 > Table shows the use of labor (hour) to produce 1 unit of output ABSOLUTE ADVANTAGE > Production Cost > Clothes (X) Food (Y) > Country A 2 x 10 = RM20 2 x 10 = RM20 > Country B 4 x 10 = RM40 1 x 10 = RM10 Country A has absolute advantage in producing clothes because has lower wage costs compared to labor in country B. Country B has absolute advantage in producing Food because has lower wage costs compared to labor in country A.ABSOLUTE ADVANTAGE 0 100 200 300 400 500 600 700 800 900 1000 1100 0 50 100 150 200 250 300 350 400 450 500 550 > Food Clothing COMPARATIVE ADVANTAGE The concept of comparative advantage evaluates a country's production capacity using the concept of opportunity cost (relative cost) > Clothes (X) Food (Y) > Country A 22 > Country B 21 Table shows the use of labor (hour) to produce 1 unit of output COMPARATIVE ADVANTAGE Assuming each country has the same total labor/time (1,000 hours), hence : Country B has an absolute advantage in food production because it can produce more food (Y) . Country A and Country B can produce the same amount of clothing (X), and it cannot be determined which country has an absolute advantage in clothing production use comparative advantage to find it .COMPARATIVE ADVANTAGE PPF curve for Country A and B COMPARATIVE ADVANTAGE SPECIALIZATION AND BENEFITS OF INTERNATIONAL TRADE Both countries benefit from international trade - consumption points lie outside the boundaries of their PPF . It is unreachable without engaging in international trade. SPECIALIZATION AND BENEFITS OF > INTERNATIONAL TRADE SPECIALIZATION AND BENEFITS OF
