4. Lecture 1: Overview4 Overview of the World Economy “Globalization” –Means different things to different people My definitions (see my online Glossary): 1. The increasing world-wide integration of markets for goods, services and capital. 2. Also the role of MNCs, IMF, WTO, World Bank. 3. Elsewhere: domination by United States. Some see good, others bad –Bad: reading by powell –Good: reading by Bhagwati Both make valid points. Read to see what they are.

5. Lecture 1: Overview5 Overview of the World Economy “Globalization” –Some aspects of globalization declined with the world recession of 2008 –The Economist, on Nov 15, 2014, reported “Signs of Life”: Globalization is back Various measures of globalization (though not all) have risen past their previous peaks The “depth” of trade (its volume) has increased The “breadth” of trade (number of borders crossed) has not fully recovered

6. Lecture 1: Overview6 Overview of the World Economy International Economics –Is NOT about countries –It IS about interactions among countries

7. Lecture 1: Overview7 Lecture 1 Outline Overview of the World Economy “Globalization” Elements of the World Economy Ways that Countries Interact –Trade –Capital Flows –Migration Policies that Affect Others

8. Lecture 1: Overview8 Overview of the World Economy World Economy consists of –Countries: a few hundred (CIA lists about 240) (WTO has 160 members) –People: over 7 billion (7.216 b. 1/5/15, compare 320 m. US) –Land: about 15 times the US

9. Lecture 1: Overview9 (Aside, on getting information) An excellent source of information about countries is the CIA World Fact Book (Just Google “fact book”)

10. Lecture 1: Overview10 Overview of the World Economy World Economy consists of –GDP (2013 est., per CIA, in US$) World:Total = $87.25 trillion per capita =$13,100 US:Total = $16.72 trillion per capita =$52,800

11. Lecture 1: Overview11 Overview of the World Economy Implication –US is very unusual Very rich –US has less than 5% of world population but almost 20% of world income

12. Lecture 1: Overview12 Lecture 1 Outline Overview of the World Economy “Globalization” Elements of the World Economy Ways that Countries Interact –Trade –Capital Flows –Migration Policies that Affect Others

13. Lecture 1: Overview13 Overview of the World Economy Ways that countries interact economically –Trade (per CIA, 2013 est.) World exports: $18.71 trillion (compare world GDP of $87 trillion) World trade has grown faster than world GDP most years –But not during 2008-9, due to world recession

17. Lecture 1: Overview17 Who Trades the Most? Developed countries are the biggest traders China is catching up, in trade volume –It was the #3 exporter six years ago when I taught the course; now it’s #2 and closing in on EU. –Others are gaining as well: Four years ago Canada was #5 exporter. Three years ago that was S Korea

18. Lecture 1: Overview18 Who Trades the Most? See Economist from about a year ago: “Trading Up: Picking the world champion of trade” –China claimed to have surpassed US. True only for goods, not goods + services But with time China will pass US in both –China’s trade per GDP is much larger than the US, but below world average –Much of the value in China’s exports is imported inputs, thus low “value added.”

19. Lecture 1: Overview19 Who Trades the Most? “Emerging Markets” in general are catching up to, or surpassing, the developed countries –In GDP, trade, and more –See Economics Focus from The Economist, “Why the Tail Wags the Dog”

23. Lecture 1: Overview23 North America, Europe, and Asia trade mostly within their group Poorer regions – Latin America, Africa – trade mostly with the richer regions This reflects what is not so clear in the table: –Rich countries trade most with each other –Poor countries trade most with rich countries But their trade with each other is growing

25. Lecture 1: Overview25 What Does the World Trade? Biggest traded category: manufactures Fastest growing, then shrinking, then growing: “fuels & mining” Why? Because this is the value of trade, and prices of oil and other raw materials were rising, and then falling. But within Manufactures, Iron & Steel is even more volatile:

29. Lecture 1: Overview29 What Does the US Trade? US imports are much larger than US exports –(We’ll see what that means later in the course.) US is a big… –Exporter of agricultural products –Importer of oil –Exporter and importer of capital goods (i.e., machines for making things)

31. Lecture 1: Overview31 Importance of Trade for Countries? Even though we trade more than most, US trade is a smaller part of US GDP than for many other countries Others that are low: Japan, Nepal (even lower than US) Note Singapore: Exports can be more than GDP. –Reason: Exports are made using imported inputs, so value of exports includes imports.

38. Lecture 1: Overview38 US Investment Position (Qualification: “Owe” isn’t quite right. This includes all assets in the US owned by foreigners, including land, buildings, etc. Not just what we’ve borrowed.) Lessons: –US is a large net “debtor” (result of our spending more than we earn) –Most of this today is government, but some is private

44. Lecture 1: Overview44 Overview of the World Economy Aside on Tariffs –We will be dealing a lot with these –See reading by Hufbauer and Grieco: US tariffs are much lower than they used to be (average 4% now, vs. 40% in 1946) US has gained a great deal from lowering tariffs US still has much to gain from further lowering But there are also severe costs for some people and firms who compete with imports

45. Lecture 1: Overview45 Overview of the World Economy Aside on Tariffs –Tariffs could go up: WTO enforces only upper limits on tariffs Actual tariffs in many countries are below these limits, and could legally rise There was danger that the recent world recession would push countries to do that. –They didn’t – at least not much.

46. Lecture 1: Overview46 Overview of the World Economy Aside on Tariffs –45% of US exports go to developing countries –US tariffs are much higher against developing countries than against developed countries

47. Lecture 1: Overview47 Overview of the World Economy Other ways that countries interact economically –Policies that affect other countries Indirect –Subsidies (esp. agriculture) »US farm subsidies > foreign aid (see CGD reading) –Macro policies (monetary, fiscal) »Exchange-rate policies –Environmental policies –Standards »Labor »Health & safety »Norms
