Extent of globalization October 15, 2007
Topics covered in this set of lectures • Major concerns and different perspectives of trade. • Statistics showing evolution and current importance of trade in economies • Reasons for increases in trade. • Public opinion
Major environmental and poverty concerns • Last 50 years population increased by a factor of 2.5, global economy increased by a factor of 5, and trade increased by a factor of 14. • 1.3 billion live on less than a dollar a day • Last 50 years CO2 emissions increased by a factor of 4; 25% of fish stocks are depleted or under threat; increased water shortages.
Differing perspectives on globalization and environment • Trade perspective: emphasizes efficiency gains from trade; governments are too responsive to domestic producers and require a “commitment device” (e.g. international rules). • Environmental perspective: emphasizes market failure; also sees government as vulnerable to capture by producer groups.
Development perspective • Priority is to reduce current poverty. • Current trade rules unfair. Limited market access; subsidies in key sectors – ag and textiles; TRIPS. • Rich countries will look for loopholes to avoid reforms, e.g. restrictions based on labor or environmental concerns (a “Trojan horse”). • Unfair to require developing countries to sacrifice for global environmental problems. • Tension between environmental NGOs in rich countries, and developing countries
The extent of globalization • During 1960s – 80s growth rates of world trade and world consumption began converging. • In the 90s trade grew more rapidly than consumption: increasing globalization. • Is the wave of globalization during 1990s- present a “repeat” of globalization during late 19th, early 20th century? (Earlier wave reversed by war and depression.)
Compare current period and 1870s –1913 • In both periods trade grew faster than consumption, fall in transportation and communication costs, treaties lower tariffs. • Table shows imports+exports as % of GNP. (Numbers are similar) • Next slide shows that for some (but not all) countries, trade in manufacturing became a more important component of manufacturing.
% Share of value of manufacturing exports as a fraction of manufacturing value added
Importance of globalization to US economy • Traded goods sector defined as agriculture, mining and manufacturing. • This sector declined from 33% to 19% of US economy, from 1960 to 1999 – even smaller today. • Merchandise exports as a share of GDP has not changed much. (Traded goods sector has shrunk, but trade has become more important to the sector.) • 17% of US labor force in manufacturing, down from 40% in 1960. Similar trend even in developing countries, e.g. China.
Capital goods have become more important in composition of US imports • From 1950 - 2000 the % of consumer goods in trade fell from 38% to 30%, industrial materials and supplies fell from 61% to 25% and capital goods rose from 1% to 45%. • Trade restrictions increase the cost of production, erode a nation’s productivity.
Services are being traded • Services are becoming more important in economy, and trade is becoming more important in service sector. Services account for about a quarter of the value of US exports and a sixth of the value of imports. • In 2000 in US, value of goods and service exports = 11% of GDP (8% merchandise, 3% services). • In 2000 value of goods and service imports approx 15% of GDP (Merchandise imports = 12% and services = 2%).
Foreign direct investment (FDI) • US FDI (as a % of GNP) has increased by a factor of three from 1960 – 1996. • In 1998 US companies exported $993 billion worth of goods to foreign consumers and sold $2800 billion through foreign affiliates. • Foreign companies sold $1,100 billion to US consumers by trade, and they sold $1,700 billion to the US through foreign owned affiliates in US.
Vertical Specialization • Countries import components, process them, and export the processed goods. Commodities may cross a border several times. • Example of US-Canada auto trade. The US exports engines and parts to Canada and imports finished cars. • In 1998 US imported $93 billion from Mexico, about 14 billion of which was accounted for by US-made components. • Difficult to determine the “true origin” of some products.
Early theories for why trade might decrease over time For a time economists thought that trade might diminish over time because: i) Spread of technology might lead to smaller differences across nations, hence less reason to trade. ii) Rising income shifts demand toward non-traded goods.
Why has trade increased? • (explains 65% of increase) Income growth and changing patterns of consumption (e.g. increased variety). • (explains 25% of effect) Liberalized policies (Examples: the average tariff on manufactured goods has fallen from 40% to 5% in the post WWII period; formation of EC and NAFTA also reduces trade restrictions. • (explains 10% increase) Decreased transport and transactions costs. Decrease in transport costs over past 50 years is equivalent to reducing tariffs from 20% to 5%)
Is current economic integration large or small? • Compared to what? • Compare to historical level (as above) • Compare to an “ideal”. What would be volume of trade if there were no borders or transport costs? • US responsible for about 25% of world production. Absent a “home bias” we would import about 75% of consumption. Instead we import about 12%.
Public opinion regarding trade • 1999 poll showed 60% of Americans in favor of globalization. • 1996 poll, 70% thought that trade was good for US economy. Most thought US should reduce trade barriers in exchange for partners’ reductions. • Opinion more divided on specific initiatives (NAFTA, normalized relations with China)
More on public opinion • Common perception is business benefits more than workers from trade liberalization. • Large majority thought that protecting labor standards should be part of trade agreements. • People with more education more favorable to trade. • More willing to accept increased trade caused by technological changes (viewed as “natural”) rather than increases caused by policy changes (e.g. normalized relations with China).
