C) Governments do not always act in the national interest when they intervene in the economy.
Instead special interest groups may influence governments. Thus, a further reason for not
embracing strategic trade policy, according to Krugman, is that such a policy is almost certain to
be captured by special interest groups within an economy, who will distort it to their own ends.
DEVELOPMENT OF THE GLOBAL TRADING SYSTEM
A) Many governments recognize the value of unrestricted free trade, but are hesitant to unilaterally
lower their trade barriers in case other countries do not follow suit. Since World War II, an
international trading framework has evolved that enables governments to negotiate a set of rules to
govern cross-border trade and lower trade barriers. For the first 50 years, the framework was
known as the General Agreement on Tariffs and Trade (GATT). Since 1995, it has been known as
the World Trade Organization (WTO).
From Smith to the Great Depression
B) Up until the Great Depression of the 1930s, most countries had some degree of protectionism.
Great Britain, as a major trading nation, was one of the strongest supporters of free trade.
C) Although the world was already in a depression, in 1930 the United States enacted the Smoot-
Hawley Act, which created significant import tariffs on foreign goods. As other nations took
similar steps and the depression deepened, world trade fell further.
1947-1979: GATT, Trade Liberalization, and Economic Growth
D) After WWII, the United States and other nations realized the value of freer trade, and
established the General Agreement on Tariffs and Trade (GATT).
E) The approach of GATT (a multilateral agreement to liberalize trade) was to gradually eliminate
barriers to trade. Over 100 countries became members of GATT, and worked together to further
liberalize trade.

1980-1993: Protectionist Trends
F) During the 1980s and early 1990s the world trading system as “managed” by GATT came under
strain. First, Japan’s economic strength and huge trade surplus stressed what had been more equal
trading patterns, and Japan’s perceived protectionist (neo-mercantilist) policies created intense
political pressures in other countries. Second, persistent trade deficits by the United States, the
world’s largest economy, caused significant economic problems for some industries and political
problems for the government. Third, many countries found that although limited by GATT from
