2Extension of Trade Theory Comparative advantage & its relationship with globalizationProduction possibilities frontier & trade theory
31.1 Production possibilities frontier & trade theory A. Production possibilities frontier (PPF)B. Trade theory
4A. Production possibilities frontier To learn about the PPFTo understand the slope of the PPF reflects opportunity costTo analyze how changes in the quantity of resources & production technology affect the PPFTo explain why the PPF is concave to the origin
5What is a production possibilities frontier? Shows the locus of the maximum output combinations of two goods given the existing resources endowment & technological level.
6The opportunity cost of production Marginal cost of the good on the x-axis = Slope of the PPFAssumption: Marginal cost is constant.PPF is a downward sloping line.Production pointGood X (units)Good Y (units)A6B14C2D3The slope of the PPF is the marginal cost of the good on the x-axis.The maximum output combinations of goods that are attainable.
7Changes in the PPF Change in resources in resources Parallel outward shift of PPF
8Changes in the PPF Advancement in technology Advancement in technology Intercept of the PPF
9PPF is concave to the origin Diminishing marginal returns= The marginal cost will finally rise PPF is generally concave to the origin
10B. Trade theory To understand the consumption choice under autarky To learn about the trade lineTo examine how international trade expands consumption possibilitiesTo explain comparative costs & gains from trade with the PPF
11Trade theory Consumption choice in an autarky economy The consumption possibilities frontier shows the locus of the maximum combinations of consumption of an economy.
12Trade theory Trade line Trade line: A straight line passing through the production point, which shows the consumption opportunities brought by trade.Slope of trade line= Terms of trade= Relative price of Good XBlue area: The increased consumption possibilities with trade.
13Trade theory Changes in consumption possibilities Specialization and trade according to the principle of comparative advantage further expand consumption possibilities.Blue area: The increased consumption possibilities.Trade line= Consumption possibilities frontier
14Two-country model Comparative cost Country A: Comparative advantage & specialization in producing Y.Country B:Comparative advantage & specialization in producing X.
15Two-country model Gains from trade Assumptions: (1) specialization according to comparative advantage; (2) there is trade; (3) terms of trade: 1X = 1YConsumption possibilities Total gains from trade:2X & 2YCountry ACountry B
161.2 Comparative advantage & its relationship with globalization A. What is economicglobalization?B. The effects of globalization
17A. What is economic globalization? To understand the concept of economic globalizationTo analyze comparative advantage & its relationship with globalizationTo examine the controversies over economic globalization
18What is economic globalization? The process of which international trade and production activities across countries or regions become more frequent.
19Integration of worldwide markets Goods markets(1) International trade (3) Firms: competition (2) Trade barriers (4) Consumers: choice
20Integration of worldwide markets Financial & investment markets(1) Capital flow across countries (2) Global expansion of financial markets (3) Foreign direct investment (FDI)
21Integration of worldwide markets Labour market(1) Immigrants & imported labour
22Integration of worldwide markets Labour market(2) Outsourcing / relocation of tasks
23Integration of worldwide markets Labour market(3) Networked labour market Firms: Production costs Workers: Job opportunities Competition
24Globalization of production activities Changes in the nature of international division of labourThe specialization of the part of a good which a country or region has a comparative advantage in the global production chain.
25Globalization of production activities Dynamic comparative advantage The comparative advantage in a good or component part will shift from one region to another along with changes in economic development.
26Globalization of production activities The expansion of the organization & scale of enterprisesThrough foreign direct investments, the scope of expansion of large enterprises is extended from developed countries to emerging markets.
27Globalization of production activities The increasingly networked business modelsOnline tradingOnlineBookshopOnlineShoppingOnlineauctionOnlinePayment
28International economic cooperation (1) International organizations that promote global trade andeconomic cooperations.(2) Arrangements that facilitate regional economic cooperation.(3) The formulation & implementation of international standards.
29B. The effects of globalization To learn about the gains from trade brought by globalizationTo analyze the effects of globalization on labour, income distribution & capital flow across countriesTo analyze the effects of globalization on multinational enterprises, small enterprises & consumers
30The effects of globalization Gains from tradeConsumers: Choice World output Average production cost Prices Globalization:(1) Enhances economic growth.(2) Gives consumer more choices.
31The effects of globalization Employment opportunities & income A change in income distribution(1) Economic restructuring(2) Labour demand & supply (3) Differences in the mobility of production resources
32The effects of globalization Effects of capital flow across countries(1) Enhancing global economic growth(2) Financial risks Market competition Environmental conservation
