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”

North America, Europe, and Asia trade mostly within their group

  • 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:

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:

Reason: Very sensitive to investment, thus to expansion and contraction.

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)

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.

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

  • Other ways that countries interact economically
    • Migration
      • Temporary
        • Guest workers
        • Day workers
      • Permanent
      • In practice, most (all?) countries limit migration severely

The World Economy

  • Other ways that countries interact economically
    • Policies that affect other countries
      • Direct
        • Trade policies (tariffs, quotas)
        • Foreign aid
        • Capital controls
        • Exchange rate management
        • Immigration restrictions
      • Indirect

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

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.

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

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)
        • Environmental policies
        • Standards
          • Labor
          • Health & safety
          • Norms

Next Time

  • Institutions of the International Economy
    • What are they?
      • The WTO
      • The IMF
      • The World Bank
      • The OECD
    • What’s happening (or not happening) now?
