Effects of Tariffs and Protectionism on International Trade

Introduction

The impact of trade policies in a highly interconnected economy such as the growth, competitiveness and consumer welfare is significant when it comes to a globalized economy. In the past decade, approaches to protectionist policy have reemerged (specifically, tariffs) in response to the local industry protection and to address trade imbalances. However, although such practice may alleviate some of the plight of some of the industries in a few ways, it is more likely to generate distortions in global trade, higher cost and cause retaliatory policies that would disorient the global economic stability.

This article examines the economical effects of tariffs and protectionism, its recent revitalization and its future effects on the dynamics of trade in the world.

Survive of Tariffs and Protectionism

Tariffs refer to taxes that the governments charge on imported goods. Their main reasons are to shield local industries against foreign competition, increase revenues, and eliminate trade imbalances. Protectionism is a more general term, which encompasses tariffs, quotas, subsidies and regulations aimed at limiting imports and encouraging domestic production.

Traditionally, protectionism was applied to developing industries a policy referred to as infant industry protection. But in the globalized markets of the modern times this kind of action tends to disorganize the supply chains and curtail consumer choices.

Historical Context: Historical Lessons

There are also protectionist inclinations that have been witnessed in various periods of the economy. During the great depression, the Smoot-Hawley Tariff Act of 1930 in the United States was passed to increase the importation taxes on thousands of goods. It was meant to save American jobs but it was a trigger to retaliatory tariffs by the trading partners which worsened the world economic recession.

To eliminate such situations, after World War II, organizations such as the General Agreement on Tariffs and Trade (GATT) and the World Trade Organization (WTO) were formed globally. Such structures encouraged the free trade and the last several decades were characterized by economic growth and globalization. The recent revival of nationalist and populist politics has however revived the spirit of protectionism in some of the key economies.

Recent Resurgence: The Trade War Era

The U.S.-China trade war, which started in 2018, is the most remarkable example of protectionism in modern times. The U.S. placed tariffs on more than 360 billion of Chinese products claiming unfair competition and theft of intellectual property. China responded with its own tariffs on American exports especially agricultural goods.

The world trade volume has decreased by the lowest level of 0.3% in 2019, compared to the 5.7 percent in 2017, according to the World Bank data, which ranks among very poor results in ten years. International investment was retarded, supply chains were compromised and most of the export-led economies were the collateral casualties.

Economic Mechanisms: The Way Tariffs can distort Trade Flows

The effects of tariffs on trade flows take place in several ways:

1. Price Effects – Tariffs make the imported goods expensive. This causes local substitutes to be more competitive but increases the prices of consumers and businesses that use imported inputs.
2. Trade Diversion – The importers tend to move to other suppliers in those countries that were not subjected to tariffs. Indicatively, after U.S. tariffs on Chinese products, there was a boom in imports of Vietnam, Mexico and Taiwan.
3. Retaliation and Uncertainty – Trade partners are likely to also retaliate with retaliation tariffs which bring about increased trade tensions. This uncertainty will not favour long term investment.
4. Supply Chain Disruption – Intermediate goods in the modern interconnected economy travel across the borders several times. Tariffs create a rise in the cost of production, decreasing efficiency and profitability within the whole industries.

Overall, although the intention of tariffs is to stimulate national development, their spillovers tend to spread around the world, to the industries that are often located far away and even outside the countries.

Case Studies: Sectoral Impact
1. Manufacturing and Technology

The technological industry, which closely depends on the international supply chains, was seriously impacted in the course of the U.S.-China trade war. Electronic and machinery tariffs made such companies as Apple and Tesla rethink their sourcing policies. Most companies started “China+1” diversification, and spread the manufacturing to such destinations as India, Vietnam, and Thailand.

2. Agriculture

Retaliation tariffs affected American farmers to the point of being some of the worst affected. The tariffs that China imposed on soybean and other agricultural imports saw the U.S. exports reduced drastically. Even though the subsidies partly offset farmers, world agricultural trade trends changed, Brazil became a significant provider to China, to name a few.

3. Steel and Aluminum

In 2018, the U.S. tariffs on steel and aluminum were explained by national security reasons. Although domestic production improved slightly, there were higher costs of inputs in downstream industries like construction and manufacture of automobiles. Research by Peterson Institute of International Economics approximated that each saved job in steel would save American consumers approximate $900,000 per annum.

Global Ripple Effects

Protectionism does not work in a vacuum. Its influence has many dimensions of international commerce:

Emerging Economies: Developing countries that rely on exports heavily including the Southeast Asian countries are the common victims of international trade tensions.

Multilateral Institutions: The WTO has struggled with implementing trade regulations in the context of increasing the unilateral policy. It has suffered a compromised dispute resolution system, which negatively affects the international governance.

Currency Movements: Exchange rate may be influenced by trade barriers. As an example, in case of trade wars, the countries in question can undervalue their currencies to keep their exports competitive.

Inflationary Forces: The rise of the import prices leads to inflation as witnessed in the U.S in 2018-2019 with tariffs causing a rise in the prices of consumer goods and industrial inputs.

The Broader Shift: Globalization to Slowbalization

Globalization was at its highest in 1990-2010. Nevertheless, the growth period of the trade has decreased compared to the world GDP since the 2010s – a factor known as slowbalization.
This has been slowed down by protectionist actions, reshoring, and geopolitics.

This change was further increased by the COVID-19 pandemic. When the global supply chains collapsed, nations started focusing on the economic resilience rather than the efficiency. Governments are currently encouraging strategic independence, especially of vital industries such as semiconductors, medicines and defense gear.

Prospectus: The Direction to a Fragmented Global Economy

Competing trends may determine the future of global trade:

1. Regional Trade Blocs – Regional trade agreements such as the Regional Comprehensive Economic Partnership (RCEP) and the single market of the European Union are influencing closer regional trade relationships to some extent counteracting global fragmentation.

2. Trade Digital – Although the level of goods trade might reduce, digital and services trade are growing at a high rate, establishing new ways of interdependence.

3. Green Protectionism – The next generation of trade policy will possibly be carbon border taxes and environmental regulations (such as the Carbon Border Adjustment Mechanism used in the EU) the border between sustainability and protectionism is faded.

4. Strong Supply Chains – Companies are also concentrating on diversifying, as well as on the concept of friend-shoring, whereby transactions are made with partners who are politically inclined.

These changes could cause global trade to be less efficient but will lead to a more steady one in the long run.

Conclusion

Politically attractive protectionist policies and tariffs tend to cause more problems than solutions. They increase the prices, destabilize the supply chains, and cause retaliation–a low global welfare outcome. Although strategic protectionism is a plausible policy in national security concerns or sustainability, it has to be precisely balanced to prevent a wider impact on the economy.

What the history and the contemporary experience have to teach, is simple: the trade flourishes on the conditions of stability, openness and collaboration. Since countries are faced with the difficult choice of between local interests and common good of an open international trading system, it is difficult to maintain equilibrium amidst the reality of a multipolar world.
