Mercantilism vs. Laissez-Faire: The Origins of Modern Trade Wars

 


Mercantilism and Laissez-Faire were two of the most influential economic philosophies and governing principles that shaped the evolution of the modern economic order. While mercantilism sought to expand national wealth through active government intervention and strict control over trade, laissez-faire emphasized market freedom and individual economic activity, advocating minimal government involvement in the economy. Together, these two schools of thought laid the foundation for the modern debate over the proper roles of the state and the market.


1. Mercantilism: A State-Controlled Economy

Mercantilism is an economic doctrine that advocates active government intervention in the economy to accumulate national wealth by regulating trade and industry.


Key Objective

Accumulation of monetary wealth, especially gold and silver.


Major Policies

Protectionism through the promotion of exports and the restriction of imports.


Key Characteristics

The government exercises strong control over the market while actively promoting colonial expansion and monopolizing overseas trade.



2. Laissez-Faire: A Market-Driven Economy

Laissez-faire is an economic philosophy, based on Adam Smith's theory of the "invisible hand," which argues that government intervention in the market should be kept to a minimum.


Key Objective

Efficient allocation of resources through the self-regulating mechanisms of the market.


Major Policies

Deregulation, expansion of free trade, and protection of private property rights.


Key Characteristics

It holds that when individuals pursue their own self-interest, they unintentionally promote the prosperity and well-being of society as a whole.



3. Historical Example


(1) The Sharp Edge of Mercantilism: England's Navigation Acts

In 1651, the government of Oliver Cromwell enacted the Navigation Acts, which required that all goods imported into England or its colonies be transported exclusively on English ships.

The Acts were a classic protectionist policy designed to weaken the Dutch Republic, which dominated maritime trade at the time, and to secure England's commercial interests. They are widely regarded as one of the most representative examples of mercantilism, demonstrating how the state actively used laws and regulations to control trade and expand national wealth.



(2) The Bible of Laissez-Faire: Adam Smith's The Wealth of Nations

Published in 1776, Adam Smith's The Wealth of Nations emerged as a direct challenge to mercantilism, which advocated strong government control over the economy. Smith argued that even without extensive state intervention, the economy could regulate itself efficiently because individuals pursuing their own self-interest would be guided by the "invisible hand"—the market's price mechanism.

The book questioned excessive government intervention in the market and laid the theoretical foundation for a free-market economy. It is widely regarded as one of the most influential works in economic history and a cornerstone in the development of modern capitalism.



4. The Influence of the Two Schools of Thought on the Modern Economic System

Mercantilism and laissez-faire can be regarded as the intellectual foundations of today's neo-protectionism and free trade, respectively.


(1) Mercantilism → Modern Neo-Protectionism

While mercantilism sought to restrict imports in order to accumulate gold and silver, modern neo-protectionism aims to protect domestic industries and workers by creating various trade barriers.

These policies extend beyond tariffs to include government subsidies, local content requirements, export controls on advanced technologies, and other forms of strategic government intervention.

Today, the strategic rivalry between the United States and China is often cited as a leading example of this modern form of mercantilism. After rapidly expanding its economic power through free trade and global integration, China began challenging U.S. economic and technological leadership. In response, the United States has strengthened protectionist measures to contain China's rise, leading to an increasingly intense trade and technology rivalry.



(2) Laissez-Faire → Modern Free Trade

The laissez-faire principle that "government should keep its hands off the market" evolved into the modern system of Free Trade Agreements (FTAs) and the World Trade Organization (WTO), both of which aim to reduce trade barriers between nations.

By eliminating tariffs and lowering other trade barriers, these institutions helped integrate the world into a vast Global Value Chain (GVC), in which production is divided across countries according to their comparative advantages.

This system enabled companies to manufacture goods in the most efficient locations and export them freely to markets around the world.

However, modern free trade has retreated significantly since the late 2010s as concerns over supply chain resilience and national security have grown. Intensifying U.S.–China strategic competition, the COVID-19 pandemic, and the Russia–Ukraine War have prompted many countries to shift away from globalization and toward more protectionist and security-oriented trade policies.

Egypt: The Breadbasket of the Roman Empire – How Was Grain Transported to Rome?

Image
In 30 BCE, Rome conquered Egypt, gaining not only a major military victory but also one of the most reliable sources of food in the ancient world. At the time, the city of Rome was home to nearly one million people, and sustaining such a vast urban population required an enormous and continuous supply of grain. It is traditionally reported that shortly after Octavian conquered Egypt in 30 BCE, the prices of grain and flour in Rome fell to roughly half of their previous levels, reflecting the secure flow of Egyptian grain into the Roman market. Egypt earned its reputation as the "Breadbasket of Rome" because of the unique natural environment created by the Nile River. Every year, the Nile's predictable floods deposited fertile silt across the surrounding farmland while providing abundant moisture for cultivation. Thanks to this annual cycle, Egypt became one of the most agriculturally productive regions in the ancient world. But how did the Roman Empire transport such enor...

The Thirty Years’ War (1618–1648): Europe’s Deadliest Religious War and the Birth of Modern International Order

Image
The Thirty Years’ War (1618–1648), which swept across Europe for three decades, was one of the most devastating conflicts in European history. It began as a religious conflict between Catholics and Protestants within the Holy Roman Empire. However, as major European powers such as Denmark, Sweden, France, and Spain became involved, it gradually developed into an international struggle for political power and influence in Europe. The German territories, which became the main battleground of the war, suffered particularly severe devastation as battles, plundering by mercenary armies, famine, and epidemics combined to inflict enormous human and economic losses. However, the Thirty Years’ War was more than simply a destructive conflict that devastated much of Europe. The Peace of Westphalia in 1648 significantly reshaped the political order of the Holy Roman Empire, while France and Sweden emerged as major European powers. At the same time, European international politics increasingly came...

Goryeo vs. North Korea: They Share the Same Name, “Korea”—So Why Did Their Political Systems Become So Different?

Image
The name “Korea” traces its origins to Goryeo, a kingdom that developed a brilliant and sophisticated culture. Interestingly, North Korea has also frequently used the name “Goryeo” in political contexts. The official name of the confederation plan once proposed by North Korea for Korean reunification was the Democratic Confederal Republic of Koryo. So, how similar are medieval Goryeo and modern-day North Korea, despite sharing the same historical name? And more importantly, how different are they? 1. Openness vs. Isolation: An Open Gateway to the World vs. a Closed Curtain ① Goryeo: A Remarkably Open Society Goryeo was an internationally connected kingdom, with Byeongnando serving as its major port for overseas trade. Merchants and travelers arrived from Song China, the Liao dynasty, Japan, and even the Arab and broader Islamic world. Goryeo society was also relatively open to foreigners. Talented immigrants could become naturalized subjects, enter government service, and in some cases...
