0. Introduction 0.1 Subject 0.1.1 International Economics Special branch of economics for a long time Merkantilists (Jean Baptiste Colbert, Adviser of Louis XIV, Classical Economists (D. Hume, D. Ricardo [Free Trade], F. List [Infant Industry], J.St.Mill) Neoclassical Economists (B. Ohlin, P. Samuelson, J.Meade, W. Leontieff), New Trade Theory (P. Krugman, E. Helpman, G.Grossman…)
Origin: Emergence of modern national states (beginning in the 16th century). • Difference to general equilibrium models (micro and macro economic models): • Factors of production not mobile between states • National borders, tariffs, quotas, standards etc. • National currencies – additional risks. Because of international trade agreements (GATT, WTO, NAFTA), currency unions, free capital movements, „globalization“ distinction between international and interregional trade blurred.
0.1.2 Branches of International Economics 0.1.2.1 Monetary International Economics • Focus on macroeconomic issues – macroeconomics of open economies • Exchange rates • Balance of payments • Optimal Currency Areas • Monetary and fiscal policies in open economies
0.1.2.2 International Trade • Microeconomic focus • Flows of goods and services are usually treated like in a pure barter economy • Why is trade taking place? • What determines the composition of the flows of goods and services into and out of countries? • How does trade affect domestic production? • What determines the volume of trade?
Who benefits from trade? • What determines the terms of trade ([index of export prices]/[index of import prices]) • What are the effects of trade policies (quotas, tariffs, Voluntary Export Restraints) • What is the (potential) role of strategic trade policy? • How are trade policies determined? • What is the role of multinational enterprises? • What are the causes and consequences of migration?
Global daily turnover in traditional foreign exchange markets: • 2004: $1.9 trillion (dt.Billionen) • 2001: $1.1 trillion (57% nominal rise, 36% at • constant exchange rates) • Global daily turnover in foreign exchange and interest rate derivatives contracts: • 2004: $2.4 trillion, growth since 2001 in real terms: • 51%. • Both segments are nearly the same Financial centers: London, New York, Paris
Reasons for growth of world trade Liberalization (GATT, WTO) Regional Trade Agreements (EFTA, NAFTA) Opening up of several countries (China) Improved Transport Facilities Multinational Corporations
0.3 Comparative Advantage Core of international trade theory: Every country exports (on average) those goods whose relative prices in autarky are below their relative world market prices. Example: two countries – two goods: beer and notebooks. • Autarky prices in Germany: 800 €/barrel, 2400 € , relative price of beer: 1/3 • Autarky prices in Austria: 900 €/barrel, 4500 €, relative price of beer : 1/5; • Germany: forego 3 barrels of beer for 1 notebook, • Austria: forego 5 barrels of beer for 1 notebook • At any relative price of beer between 1/3 und 1/5 Pareto-improvement, if Austria exports beer and Germany exports notebooks.
Reasons for comparative advantages: 1. Different preferences, 2. different technologies, 3. different factor endowments, 4. increasing returns to scale, 5. others. First reason: of little theoretical interest, reasons two and three: subject of traditional theory, remaining reasons dealt with in recent theories (imperfect competition, IO).
