What principle or theory argues that it is in a countrys best interest to maintain a trade surplus

Mercantilism is an economic theory that advocates government regulation of international trade to generate wealth and strengthen national power. Merchants and the government work together to reduce the trade deficit and create a trade surplus.

Mercantilism—a form of economic nationalism—funds corporate, military, and national growth. It advocates trade policies that protect domestic industries. 

In mercantilism, the government strengthens the private owners of the factors of production. These four factors of production are:

  • Entrepreneurship
  • Capital goods
  • Natural resources
  • Labor

Mercantilism establishes monopolies, grants tax-free status, and grants pensions to favored industries. It imposes tariffs on imports. It also prohibits the emigration of skilled labor, capital, and tools. It doesn't allow anything that could help foreign companies.

In return for the protection provided by national government, businesses funnel the riches from foreign expansion back to their governments via taxes. Those taxes taxes pay for increasing national growth and international political power.

Mercantilism was the dominant economic system in Europe between 1500 and 1800. Countries all wanted to export more than they imported. In return, they received gold. It powered the evolution of nation-states out of feudalism. Holland, France, Spain, and England competed on the economic and military fronts. These countries created skilled labor forces and armed forces to defend them.

Merchants supported national governments to help them beat foreign competitors. An example was The British East India Company which defeated the princes of India with 260,000 mercenaries. It then plundered their riches as the British government protected the company's interests. Many members of Parliament owned stock in the company. As a result, the company's victories lined lawmakers' pockets.

Mercantilism depended upon colonialism, as the government would use military power to subdue foreign lands. Businesses then exploited natural and human resources found there. The profits fueled further expansion, benefiting both the merchants and the nation.

Mercantilism also worked hand-in-hand with the international gold standard. Countries paid each other in gold for exports. The nations with the most gold were therefore the richest. They could hire mercenaries and explorers to expand their empires. As a result, nations sought trade surpluses with which to amass gold, rather than a deficit.

Success within mercantilism depended on reliable shipping and transportation. Control of the world's waterways was vital to national interests.

Successful mercantilist nations developed strong merchant marines and imposed high port taxes and regulations on foreign ships arriving with goods to sell. England, for example, required all imports from Europe to come in its own vessels, or in a vessel registered in the country where the goods originated.

Democracy and free trade ended mercantilism's dominance in the late 1700s. American and French revolutions formalized large nations ruled by democracy. They endorsed capitalism rather than mercantilism. 

Adam Smith argued against mercantilism with his 1776 publication of The Wealth of Nations. He argued that foreign trade strengthens the economies of both countries involved, as long as each trading partner specializes in what it produces best, giving it a comparative advantage. He also explained that a government that put business ahead of its people would not last. Smith's economic theories coincided with the rise of democracy in North America and Europe.

In 1791, mercantilism was breaking down, but free trade hadn't yet developed. Most countries still regulated trade to enhance domestic growth. Then-U.S. Treasury Secretary Alexander Hamilton was a proponent of mercantilism. He advocated government subsidies to protect infant industries necessary to the national interest. The industries needed government support until they were strong enough to compete with established foreign industries and producers. Hamilton also proposed tariffs to reduce competition in those areas.

Fascism and totalitarianism adopted mercantilism in the 1930s and 1940s. After the stock market crash of 1929, many nations turned toward trade protectionism to save industry and jobs. They responded to the Great Depression with tariffs and trade restrictions.

In the U.S., the 1930 Smoot-Hawley Act raised tariffs on more than 20,000 items. When other countries retaliated, global trade fell 66% by 1933, prolonging the depression. 

World War II's devastation forced Allied nations into desiring global cooperation. They created the World Bank, the United Nations, and the World Trade Organization. They saw mercantilism as dangerous and globalization as the alternative.

But not all nations agree that trade liberalization is in their interests.

Both Russia and China continue to promote a form of mercantilism. In fact, neomercantilism fit with those nations' formerly communist governments. They relied on centrally planned command economies that allowed them to regulate foreign trade. They also controlled their balance of payments and foreign reserves. Their leaders selected which industries to promote. They engaged in currency wars to give their exports lower pricing power. For example, China bought U.S. Treasurys to fuel its trade with the U.S. As a result, China became one of the largest foreign owners of U.S. debt.

Mercantilism laid the foundation for today's nationalist and protectionist economic policies. Nations felt they lost power as a result of globalism and the interdependence fostered by free trade.

The Great Recession, like the Great Depression, aggravated a tendency toward mercantilism in capitalist countries. For example, in 2014, India elected Hindu nationalist Narendra Modi. In 2016, the United States chose Donald Trump for the presidency. Some observers considered Trump's policies a form of neomercantilism.

In response, leaders like U.S. President Donald Trump advocated expansionary fiscal policies, such as tax cuts, to help businesses. He also argued for bilateral trade agreements between two countries, rather than multilateral agreements between many countries. Mercantilism opposes immigration because it takes jobs away from domestic workers. Trump's immigration policies followed this mindset.

In 2018, Trump's mercantilist mindset contributed to his launch of a trade war against China. Trump imposed tariffs on Chinese imports, and China responded with its own policies that hurt U.S. exports. Despite announcing a "Phase 1" deal to end the trade war in 2020, President Trump left office without ending the trade war. In fact, with roughly a week left as president, the Trump administration imposed a new round of trade restrictions covering tomato and cotton products from China, citing concerns over slave labor in China.

  • With mercantilism as their economic system, nations focus on building their strength and dominance through regulating trade and increasing net exports.
  • Mercantilism uses taxation, tariffs, and other regulations to limit the outward flow of anything that would help other countries.
  • The foremost economic system of Europe from about 1500 to 1800, mercantilism relied heavily on colonization to maximize exports.
  • Capitalism and globalization rose during the 20th century, mostly replacing mercantilism (except in the case of fascist countries with protectionist agendas).
  • Some countries, such as Russia and China, still lean toward a neo-mercantilist approach in place of trade liberalization.

Mercantilism is an economic system that seeks to promote the development of national business and industry over foreign business and industry. Mercantilists promote policies that seek to create trade surpluses for their own nations and use the resulting wealth to further promote national economic goals and national businesses.

Mercantilism was a cooperative relationship between a nation's business and trading classes and its government. Domestically, mercantilist governments support local industries with investment, favorable taxes, and other benefits while protecting it from foreign competition with tariffs and other trade restrictions. Internationally, mercantilist governments support local business expansion with strong armed forces and large navies and merchant shipping to protect access to raw materials and markets.

Which of the following argues that it is in a country's best interest to maintain a trade surplus?

Principle of mercantilism. The main tenet of mercantilism was that it was in a country's best interests to maintain a trade surplus, to export more than it imported.

Which of the given options is suggested by the theory of comparative advantage?

The theory suggests that total economic welfare in all countries is improved when countries focus on those industries where they have have the highest expertise and success, and the lowest opportunity costs.

When a country has a comparative advantage in the production of a good?

In economic terms, a country has a comparative advantage when it can produce at a lower opportunity cost than that of trade partners. While a country cannot have a comparative advantage in all goods and services, it can have an absolute advantage in producing all goods.

Which of the following is a classical theory of international trade?

The classical theory of trade is based on the labour cost theory of value. This theory states that goods are exchanged against one another according to the relative amounts of labour embodied in them. Goods which have equal prices embody equal amounts of labour.
