Understanding Tariffs

A comprehensive guide to what tariffs are, their historical context, and their impact on the U.S. economy throughout history.

What Are Tariffs?

Tariffs are taxes imposed by governments on goods and services imported from other countries. They serve as a trade policy tool used by governments to generate revenue, protect domestic industries, and as leverage in international trade negotiations.

Types of Tariffs

•
Ad Valorem Tariffs: Calculated as a percentage of the imported good's value (e.g., 25% on imported steel).
•
Specific Tariffs: Fixed fee based on the weight or quantity of the imported good (e.g., $0.25 per pound of imported cheese).
•
Compound Tariffs: A combination of both ad valorem and specific tariffs.
•
Tariff-Rate Quotas: Lower tariff rates for imports up to a specified quantity, and higher rates for imports exceeding that quantity.

How Tariffs Affect Us

Tariffs have complex impacts that ripple through the economy, affecting different groups in different ways:

Consumers

Typically face higher prices for imported goods and their domestic substitutes. This reduces purchasing power and standard of living.

Domestic Producers

Competing with imports receive protection from foreign competition, potentially allowing them to raise prices and increase production.

Workers

May see job creation in protected industries but job losses in industries that use imported inputs or face retaliatory tariffs.

Government

Collects revenue from tariffs, but may face diplomatic challenges and potential retaliation from trading partners.

Historical Tariff Implementation in the U.S.

Early Republic Era (1789-1860)

The first tariff law was passed in 1789, shortly after the Constitution was ratified. During this period, tariffs were the federal government's primary source of revenue, accounting for about 90% of government income.

Key Events:

Tariff of 1816: First explicitly protective tariff, designed to shield nascent American industries from British competition after the War of 1812.
Tariff of 1828 ("Tariff of Abominations"): Highly controversial protective measure that raised rates to nearly 50% and contributed to sectional tensions between North and South.
Compromise Tariff of 1833: Gradually reduced tariff rates to resolve the nullification crisis with South Carolina.

Economic Impact: Helped establish American manufacturing but created sectional tensions. Northern manufacturers benefited while southern agricultural exporters faced higher costs and potential retaliation from trading partners.

Civil War to Progressive Era (1861-1920)

This period saw generally high tariff rates, with Republicans favoring protectionism to support industrial development and Democrats generally advocating lower tariffs.

Key Events:

Morrill Tariff of 1861: Raised rates significantly to generate revenue for the Civil War.
McKinley Tariff of 1890: Raised average duties to nearly 50%, the highest in U.S. history to that point.
Underwood Tariff of 1913: Significantly reduced rates under President Wilson, representing a rare Democratic victory on tariff policy.

Economic Impact: Supported rapid industrialization but contributed to monopolistic practices and trusts. The high tariffs helped American industry grow to become the largest in the world by 1900, but also led to higher prices for consumers.

Smoot-Hawley and Great Depression (1930s)

The Smoot-Hawley Tariff Act of 1930 raised tariffs on over 20,000 imported goods to record levels, with average rates of about 45-50%.

Economic Impact: Widely considered a policy disaster that deepened the Great Depression. It triggered retaliatory tariffs from other countries, causing U.S. exports to decline by nearly 67% between 1929 and 1933. International trade plummeted by about 66% worldwide during this period.

Post-WWII Liberalization (1940s-1980s)

The negative effects of Smoot-Hawley led to a fundamental shift in U.S. trade policy, beginning with the Reciprocal Trade Agreements Act of 1934, which allowed the president to negotiate tariff reductions.

Key Developments:

GATT Formation (1947): The U.S. led efforts to create the General Agreement on Tariffs and Trade, beginning a process of multilateral tariff reductions.
Kennedy Round (1963-1967): Achieved average tariff cuts of 35%, the largest to that point.
Tokyo Round (1973-1979): Further reduced tariffs and addressed non-tariff barriers.

Economic Impact: This period saw unprecedented growth in international trade and global prosperity. U.S. exports grew significantly, and the economy benefited from increased specialization and efficiency. However, certain industries like textiles, steel, and automobiles faced increasing foreign competition.

Modern Era of Managed Trade (1990s-2016)

This period was characterized by further trade liberalization through multilateral and bilateral agreements, but with targeted protections for certain industries.

Key Developments:

NAFTA (1994): Created a free-trade zone between the U.S., Canada, and Mexico.
WTO Formation (1995): Replaced GATT with a more comprehensive framework for trade relations.
China PNTR (2000): Granted China permanent normal trade relations status.

Economic Impact: Trade as a percentage of GDP increased significantly. Some manufacturing sectors experienced job losses due to offshoring, while consumers benefited from lower prices and greater product variety. The trade deficit grew substantially, particularly with China.

Recent Tariff Actions (2017-Present)

The Trump administration marked a significant shift in U.S. trade policy, implementing tariffs on a wide range of products from multiple countries.

Key Actions:

Section 232 Tariffs (2018): 25% tariff on steel and 10% on aluminum from most countries, justified on national security grounds.
Section 301 Tariffs on China: Multiple rounds of tariffs on Chinese goods, eventually covering about $370 billion of imports.
USMCA (2020): Replaced NAFTA with revised terms, including stricter requirements for automotive content.

Economic Impact: Studies suggest mixed results. Protected industries like steel saw some job growth, but downstream industries using these materials faced higher costs. Consumer prices increased modestly, with most of the tariff burden falling on U.S. businesses and consumers rather than foreign exporters. The Biden administration has maintained many of these tariffs while revising others and pursuing a more multilateral approach to addressing trade concerns.

Key Historical Lessons

1. Smoot-Hawley Tariff Act (1930s)

The Smoot-Hawley Tariff Act is widely regarded as a cautionary tale. By raising tariffs to historically high levels during an economic downturn, it triggered a wave of retaliatory measures from trading partners that contributed to a 66% decline in world trade. Most economists believe it deepened and prolonged the Great Depression.

2. Post-WWII Trade Liberalization

The gradual reduction of tariffs in the post-WWII era coincided with unprecedented global economic growth. U.S. economic output grew by about 2.5% annually over this period, and trade grew even faster. This suggests that open trade policies generally support economic growth, though causality is complex.

3. Targeted Industry Protection

Efforts to protect specific industries with tariffs have shown mixed results. The U.S. steel industry, for example, has been protected by various tariff and quota measures since the 1970s. While these measures have temporarily boosted production and employment in the protected industry, they have often come at a high cost to downstream industries and consumers.

4. Recent Tariff Actions (2018-present)

Studies of the tariffs implemented since 2018 suggest they had modest macroeconomic effects but significant impacts on specific sectors. Research indicates that nearly 100% of the tariff costs were borne by U.S. importers rather than foreign exporters. The Federal Reserve found that these tariffs were associated with reduced manufacturing employment and higher producer prices.

Conclusion

Throughout U.S. history, tariff policy has swung between protectionism and free trade, reflecting changing economic conditions, political philosophies, and international relations. While tariffs can provide short-term benefits to specific industries and workers, the historical record suggests that broad-based tariffs typically impose overall economic costs that exceed their benefits.

The most successful tariff policies have typically been targeted, temporary, and implemented as part of a broader strategy that includes worker retraining, infrastructure investment, and research and development support. As global supply chains become increasingly integrated and complex, the effects of tariffs have become more difficult to predict and control.

As the U.S. continues to navigate trade relationships in a changing global economy, the lessons of history provide valuable context for understanding the potential consequences of different tariff approaches.
