The Protection Racket: A History of Tariffs and Who Really Pays

An essay exploring the history, economics, and politics of tariffs, prompted by the re-imposition of sweeping new trade barriers. The request called for a detailed, nuanced, and fact-checked analysis covering the evolution of tariffs, their successes and failures, the spectrum of economic opinion, key research and researchers, and notable historical anecdotes.

In prompting Gemini to write this essay, I had a realization, one that many people have had and said before: using an LLM like this feels like having a ridiculously smart, PhD-level expert in your pocket. Someone who knows a lot about a lot.

What excites me and terrifies me in equal measure is just how much you can learn if you ask the right questions. The potential is insane. Of course, there’s nuance in how you go about learning this way. There are valid concerns about the downsides of learning from an LLM — limitations, bias, lack of depth, and so on. But still, as that famous Thomas Sowell quote goes, “There are no solutions, only trade-offs.” It fits perfectly here.

And then I think about someone with a crappy internet connection in a rural part of India or sub-Saharan Africa. Someone who has no access to quality education, no resources, nothing. Yet with just a basic connection and access to a tool like this, the number of things they can learn or do on their own is staggering.

Of course, this doesn’t mean we should ignore the tough questions around AI. Far from it. But still, these are exciting and terrifying times.

In the grand theater of economic policy, the tariff is a character actor that refuses to leave the stage. The curtain rose on its latest act on August 1, 2025, with an announcement from the White House that crystallized the new era of American protectionism.

On that day, an executive order was signed imposing a sweeping new regime of “reciprocal” tariffs. The action was vast in its scope, targeting nearly 70 countries and territories in addition to the European Union. The tariff rates varied widely, based on justifications ranging from trade imbalances to national security concerns. Rates for some nations were set as high as 41% (Syria) and 39% (Switzerland), while key trading partners like Canada saw rates increased to 35%, India was set at 25%, and the United Kingdom at 10%.

The rates on 68 countries and the 27-member European Union are set to go into effect in seven days, according to the order, and not the Friday deadline that the president initially set. The extension reflects the government’s need for more time to harmonize the tariff rates, according to a senior official who spoke to reporters on condition of anonymity.

Trump said the new tariffs were going “very well, very smooth.” In an interview with NBC News he added that it was “too late” for the countries named in Thursday’s order to avoid the tariff rates but that he was open to offers. — The Guardian

Trump said the new tariffs were going “very well, very smooth.” In an interview with NBC News he added that it was “too late” for the countries named in Thursday’s order to avoid the tariff rates but that he was open to offers.

The move was personified by the president’s direct and pointed justification for the tariffs on India, a key strategic partner.

“Remember, while India is our friend, we have, over the years, done relatively little business with them because their Tariffs are far too high — among the highest in the World… Also, they have always bought a vast majority of their military equipment from Russia, and are Russia’s largest buyer of ENERGY… INDIA WILL THEREFORE BE PAYING A TARIFF OF 25%, PLUS A PENALTY FOR THE ABOVE, STARTING ON AUGUST FIRST.”

— Donald J. Trump, via social media, August 1, 2025

This declaration is not a new play but a revival of a classic, one whose past performances have been met with both standing ovations and catastrophic set collapses. It is a tool as old as commerce itself, a seemingly simple levy on imported goods that has been wielded by emperors, revolutionaries, and modern-day populists alike. Its history is a tangled narrative of national ambition, economic anxiety, and, at times, sheer absurdity. To understand the current drama, we must first delve into the long and often contradictory history of this enduring economic instrument.

1. The Enduring Allure of the Tollbooth: A History of Tariffs

The tariff did not begin as a sophisticated tool of industrial policy. In its earliest form, it was a straightforward revenue grab. For ancient empires and medieval kingdoms, customs duties were a vital source of income, a toll exacted on the flow of goods through their territories. The Romans levied the portorium, and the great merchant republics of Venice and Genoa built their maritime empires on the customs duties that funded their navies and their art. The primary purpose was to fill the coffers of the state, not to shield domestic producers from foreign competition.

The transformation of the tariff from a simple revenue tool to an instrument of economic protection began in earnest with the rise of the modern nation-state and the doctrine of mercantilism. From the 16th to the 18th centuries, European powers viewed global commerce as a zero-sum game. The goal was to accumulate as much gold and silver as possible by maximizing exports and minimizing imports. Tariffs became a key weapon in this economic warfare, exemplified by policies like Britain’s Navigation Acts, which were designed to cripple Dutch shipping and ensure that all colonial trade flowed through England, enriching its own merchants and crown.

Mercantilism: An economic doctrine dominant in Europe from the 16th to 18th centuries, which held that a nation’s wealth and power were best served by increasing exports and collecting precious metals like gold and silver. Mercantilist policies included high tariffs on imported manufactured goods and the acquisition of colonies to serve as sources of raw materials and exclusive markets for the mother country.

The 19th century saw a great schism in tariff philosophy. Great Britain, having achieved industrial supremacy, became the world’s leading evangelist for free trade. The repeal of the Corn Laws in 1846, which had protected British agriculture, signaled a decisive shift towards a policy of open markets. Yet, across the Atlantic, a different story was unfolding. The newly independent United States, a fledgling industrial power, embraced protectionism with a fervor that would last for over a century. Alexander Hamilton, the first Secretary of the Treasury, laid out the intellectual groundwork for this approach in his 1791 “Report on Manufactures,” arguing that temporary tariffs were necessary to shield America’s “infant industries” from the might of their more established European competitors.

The Infant Industry Argument: First articulated by Alexander Hamilton, this is the most enduring economic case for protectionism. It posits that new, developing industries in a country initially lack the economies of scale and experience to compete with established foreign competitors. A temporary period of tariff protection can, in theory, shield these “infants” from imports until they are mature enough to compete on the global stage.

This protectionist stance was not without intense internal conflict, revealing the potent political economy of tariffs. The 1828 Tariff of Abominations raised duties significantly to protect Northern manufacturing, but it devastated the agrarian Southern economy, which depended on exporting cotton and importing British goods. The episode inflamed sectional tensions, led to the Nullification Crisis, and stands as a stark example of how tariffs can benefit one region at the direct expense of another, becoming a flashpoint for national division.

Despite such conflicts, this “restriction period,” as economic historian Douglas Irwin has termed it, saw the United States maintain some of the highest tariff rates in the world. From the Civil War through the early 20th century, average U.S. tariffs on dutiable goods often hovered between 40% and 50%. This was the era of the “home market” argument, a belief heavily promoted by lobbying from protected industries that a shielded domestic market was the key to national prosperity. A similar path was followed by Otto von Bismarck’s Germany, which used tariffs to unify its economy and build its industrial might.

The 20th century, however, would reveal the dark side of this protectionist impulse. The Smoot-Hawley Tariff Act of 1930, signed into law at the outset of the Great Depression, raised U.S. tariffs to their second-highest levels in history. The move was intended to protect American jobs and farms, but it backfired spectacularly. America’s trading partners retaliated with their own tariffs, and global trade plummeted by a staggering 66% between 1929 and 1934. While few economists believe Smoot-Hawley caused the Great Depression, there is a broad consensus that it significantly deepened and prolonged the crisis.

The Great Depression: The worst economic downturn in the history of the industrialized world, lasting from 1929 to 1939. It began after the stock market crash of October 1929, which wiped out millions of investors, and was characterized by soaring unemployment, widespread poverty, and a sharp decline in industrial output and international trade. The Smoot-Hawley Tariff is seen as a major policy error that exacerbated the crisis.

The catastrophic experience of the 1930s led to a dramatic reversal in global trade policy. The post-World War II era was dominated by a new consensus, institutionalized in the General Agreement on Tariffs and Trade (GATT). The primary goal shifted from restriction to reciprocity, with nations working to negotiate down trade barriers in a series of painstaking multilateral “rounds.” This process, from the Kennedy Round in the 1960s to the Tokyo Round in the 1970s, steadily dismantled the high tariff walls of the pre-war era, ushering in a period of unprecedented expansion in global trade.

This liberalizing trend culminated in the Uruguay Round, which concluded in 1994 and created the World Trade Organization (WTO) to succeed the GATT. The WTO was a more powerful and formal institution, with a stronger dispute-settlement mechanism designed to enforce a rules-based trading order. The 1990s and early 2000s became the golden age of this consensus, an era of what some economists call “hyper-globalization.” The fall of the Soviet Union and the integration of China into the WTO in 2001 seemed to cement the triumph of a liberal, open, and interconnected global economy.

And yet, the old protectionist instincts never fully disappeared; they were merely dormant. The 2008 financial crisis eroded public trust in elite economic management. This was followed by the full impact of the “China shock”, which hollowed out manufacturing communities in the American Midwest and elsewhere. A growing sense that the benefits of globalization were flowing to corporations and the wealthy while leaving working-class communities behind created a fertile ground for a new wave of populist nationalism. The purpose of the tariff also began to evolve. Today, we see the rise of the carbon tariff, such as the European Union’s Carbon Border Adjustment Mechanism (CBAM), which aims to tax imports based on their carbon footprint. This represents a 21st-century chapter, where the tariff is repurposed as a tool for regulatory and climate goals, not just industrial protection.

Carbon Border Adjustment Mechanism (CBAM): A first-of-its-kind policy tool, pioneered by the European Union, designed to put a price on the carbon emissions generated during the production of certain goods imported into the EU. Its goal is to prevent “carbon leakage”—where EU-based companies move production to countries with less stringent climate policies—and to encourage cleaner industrial production globally.

2. The Double-Edged Sword: Tariff Triumphs and Tragedies

The historical record of tariffs is a gallery of both cautionary tales and qualified successes. Proponents of protectionism often point to the 19th-century United States as a prime example of tariffs fostering industrial greatness. It is true that during its period of high tariffs, the U.S. economy grew at a remarkable rate. However, as Douglas Irwin’s research has shown, this simple correlation is misleading. U.S. economic growth was driven more by abundant natural resources, a vast and open internal market, a steady flow of immigrant labor, and a culture of innovation. While tariffs may have sped up development in a few specific industries by a few years, they also imposed costs on consumers and other sectors. The American industrial giant was likely to have emerged with or without a high tariff wall; the protectionism may have simply altered the timing and composition of that growth.

A more nuanced case for successful tariff policy can be found in the post-war development of countries like South Korea and Japan. These nations used a combination of policies, including tariffs, to nurture key industries like steel and electronics. However, these tariffs were not an isolated policy. They were part of a broader, state-directed industrial strategy that also included significant investments in education, infrastructure, and research and development, as well as a strong emphasis on exporting. The protection was temporary and targeted, designed to build industries that could eventually compete on the global stage.

In contrast, the strategy of Import Substitution Industrialization (ISI), adopted by many Latin American countries from the 1950s to the 1970s, offers a more cautionary tale. The goal was to reduce dependency on foreign imports by using high tariff walls to foster a wide range of domestic industries. While ISI produced an initial burst of industrialization, it often led to inefficient, uncompetitive companies that produced low-quality goods at high prices for a captive domestic market. Lacking the pressure of international competition and an emphasis on exports, many of these industries stagnated, contributing to debt crises and a “lost decade” of economic growth in the 1980s.

Import Substitution Industrialization (ISI): A trade and economic policy pursued by many developing countries in the 20th century. The strategy aimed to reduce dependency on foreign countries by using high tariffs and other barriers to protect domestic industries, thereby replacing foreign imports with domestic production. While it fostered some initial industrialization, it often resulted in inefficient, uncompetitive firms and long-term economic stagnation.

The more direct failures of tariff policy are often dramatic and unambiguous. The aforementioned Smoot-Hawley Tariff stands as the archetypal disaster. A lesser-known but still instructive failure was the McKinley Tariff of 1890. This act raised the average duty on imports to nearly 50%, leading to a sharp increase in consumer prices and contributing to the Republican party’s political losses in the subsequent elections. More recently, the 2009 U.S. requirement for Country of Origin Labeling (COOL) on meat products serves as a modern example of a non-tariff barrier with tariff-like consequences, provoking a successful WTO challenge and the threat of over $1 billion in retaliatory tariffs from Canada and Mexico.

The McKinley Tariff (1890): A protectionist U.S. tariff that raised the average duty on imported goods to nearly 50%. Championed by then-Congressman William McKinley, it was intended to protect American industries from foreign competition. However, it led to a sharp increase in consumer prices for everyday goods, which proved highly unpopular with voters and contributed to a major political defeat for the Republican Party in the next election cycle.

3. A Case Study in Extremes: India’s Journey with Tariffs

No story of tariffs is complete without examining India’s dramatic and instructive journey from extreme protectionism to radical liberalization. For decades after its independence in 1947, India pursued a policy of economic self-sufficiency (Swadeshi), born from a deep-seated skepticism of foreign economic influence rooted in its colonial past. This philosophy manifested in one of the world’s most formidable protectionist systems, known as the License Raj.

This was a system that went far beyond mere tariffs. It was a complex web of import licenses, industrial permits, and centralized planning that gave the government control over nearly every aspect of the economy. Tariffs were exceptionally high, with peak rates exceeding 300% on some goods, effectively sealing off the domestic market from foreign competition. The goal was to build a self-reliant industrial base from the ground up. The result, however, was economic stagnation. Sheltered from competition, domestic firms had little incentive to innovate or improve efficiency. Consumers were left with limited choices and low-quality goods, symbolized by the iconic but technologically stagnant Ambassador car. The economy grew at a sluggish pace, famously dubbed the “Hindu rate of growth.”

The breaking point came in 1991. A severe balance of payments crisis brought India to the brink of default, forcing a radical change in policy. Under the leadership of Prime Minister P.V. Narasimha Rao and Finance Minister Manmohan Singh, the government dismantled the License Raj and began a process of sweeping economic liberalization. Tariffs were slashed across the board, import licensing was largely abolished, and the economy was opened to foreign investment.

The results were transformative. The reforms unleashed decades of rapid economic growth, lifted millions out of poverty, and created a booming new middle class. India became a powerhouse in services, particularly information technology, and Indian consumers gained access to a world of goods that had previously been unimaginable.

Today, India’s tariff policy is far more nuanced. While it remains more protectionist than many Western nations, it has moved away from the blanket protectionism of the past. Under initiatives like “Make in India,” the government uses tariffs strategically. For example, by placing higher tariffs on finished smartphones but lower tariffs on their individual components, the policy encourages global firms like Apple and Samsung to set up assembly plants within India. This is a modern, targeted application of the infant industry argument, aimed not at sealing off the economy, but at attracting investment and capturing a valuable slice of the global supply chain. India’s journey thus serves as a powerful lesson on both the profound costs of extreme protectionism and the complex ways tariffs are being reimagined in the modern global economy.

4. The Unseen Costs: Who Really Pays for Protection?

A central and often misunderstood aspect of any tariff is the question of who ultimately bears its cost. While tariffs are levied on foreign goods, the tax itself is paid by the domestic company importing those goods. Economic research consistently shows that this cost is almost never absorbed by the foreign exporter. Instead, it is passed down the supply chain, first to wholesalers, then to retailers, and finally, to domestic consumers in the form of higher prices.

The Burden of the Tariff: A common political claim is that tariffs force foreign countries to “pay” for access to a market. However, the overwhelming majority of economic studies, including extensive analysis of the 2018 U.S. tariffs, found that the cost was passed on almost entirely to U.S. importers and consumers. Foreign exporters did not lower their prices to absorb the tariff; instead, the tariff acted as a direct tax on American consumption.

This creates what economists call a deadweight loss: a net loss of economic welfare. While domestic producers in the protected industry gain from higher prices and the government collects revenue, the financial loss to consumers is greater than the sum of those gains. Furthermore, the costs are not limited to consumers. Exporters often suffer when other countries retaliate. The Smoot-Hawley Tariff, for example, devastated American farmers when foreign nations slapped retaliatory tariffs on U.S. agricultural goods, causing their export markets to collapse. Similarly, the McKinley Tariff of 1890 led to such a sharp increase in the price of everyday goods that it fueled a political backlash, contributing to significant electoral losses for the incumbent party.

Deadweight Loss: In the context of a tariff, this is the net loss of economic efficiency that occurs when the consumer loss from higher prices is greater than the combined gains of domestic producers and the government (from tariff revenue). It represents value that is lost to everybody in the economy, created because the tariff distorts incentives and prevents mutually beneficial trades from occurring.

5. The Ivory Tower’s Verdict: A Spectrum of Economic Thought

For over two centuries, the vast majority of mainstream economists have viewed tariffs with a skeptical eye. The intellectual foundation for this skepticism was laid by Adam Smith in The Wealth of Nations and solidified by David Ricardo’s theory of comparative advantage. From this perspective, a tariff is a self-inflicted wound that raises prices for consumers and misallocates resources, creating a “deadweight loss” of economic welfare.

Comparative Advantage: A foundational concept in international trade theory, developed by David Ricardo. It holds that countries gain from trade by specializing in producing goods where they have a lower opportunity cost, even if they don’t have an absolute advantage in producing anything. By specializing and trading, both nations can consume more than they could in isolation, leading to mutual gains.

This mainstream view, however, has never been without its challengers. The “infant industry” argument remains the most enduring case for protectionism. A more technical justification is the “terms of trade” argument, which posits that a large country can impose an “optimal tariff” to push down the world price of its imports, thereby improving its terms of trade and capturing more of the gains from trade from its partners. While theoretically possible, this “beggar-thy-neighbor” policy is risky, as it almost certainly invites retaliation that leaves both sides worse off.

Beggar-Thy-Neighbor Policy: An economic strategy where one country attempts to remedy its economic problems through policies that worsen the economic problems of other countries. A classic example is imposing a tariff to shift domestic demand away from imports. This harms the exporting country and almost always invites retaliatory tariffs, leading to a trade war where all parties are made worse off.

A powerful historical critique comes from Cambridge economist Ha-Joon Chang. In his book Kicking Away the Ladder, Chang argues that virtually all of today’s wealthy nations, including Britain and the United States, used high tariffs and other forms of protectionism to industrialize. He contends that by now insisting on free trade policies for developing countries, they are effectively “kicking away the ladder” they themselves climbed to prosperity.

“Kicking Away the Ladder”: A thesis popularized by economist Ha-Joon Chang, arguing that wealthy, developed countries are hypocritical in their advocacy for free trade. The argument is that these nations used high tariffs and protectionist industrial policies to build their own economies but now deny those same tools to developing countries, effectively “kicking away the ladder” they used to achieve prosperity.

In the 1980s, strategic trade theory, pioneered by economists like Paul Krugman, suggested that in certain oligopolistic industries, governments could use tariffs to shift profits from foreign to domestic firms. However, Krugman himself has since become a leading critic of using this theory to justify broad protectionism, arguing the conditions required are rare and the risks of a trade war are high. Today, the debate is also informed by the distributional consequences of trade, with the “China shock” forcing a more nuanced conversation about the need for social safety nets to help those harmed by globalization.

6. The Data’s Tale: What the Research Reveals

When we move from theory to empirical evidence, the case against broad-based tariffs becomes even stronger. Studies of the 2018 Trump tariffs by economists like Pinelopi Goldberg found that their costs were borne almost entirely by U.S. consumers and businesses in the form of higher prices. The retaliatory tariffs also had a significant negative impact, particularly on American agriculture.

Furthermore, these tariffs have accelerated a reorganization of global supply chains. Research has shown a significant shift in trade and investment away from China as companies seek to avoid the tariffs. Countries like Vietnam and Mexico have emerged as major beneficiaries, but this reshuffling comes with its own costs and inefficiencies and has not led to a significant “reshoring” of manufacturing jobs back to the United States.

The literature on the “China shock,” pioneered by David Autor and his colleagues, has shown that the surge in imports did have a significant negative impact on manufacturing employment in specific U.S. communities. Their work has highlighted the real and painful costs of trade adjustment. However, most economists, including Autor, argue that a better response is to strengthen domestic policies that help workers, such as job training and relocation assistance, rather than imposing tariffs that act as a broad tax on the entire economy. This is supported by decades of research, such as the seminal study from the Peterson Institute for International Economics, Measuring the Costs of Protection in the United States, which famously calculated that trade barriers cost American consumers hundreds of thousands of dollars annually for each job “saved” in a protected industry.

The “China Shock”: A term referring to the period of rapid growth in Chinese exports to the U.S. following China’s entry into the WTO in 2001. Seminal research on this phenomenon found that U.S. communities more exposed to Chinese import competition experienced significant, long-lasting negative impacts, including higher unemployment, lower labor force participation, and reduced wages, particularly in manufacturing.

7. The Tariff Titans: Scholars Shaping the Debate

The modern debate over tariffs is shaped by a number of influential economists whose research provides the intellectual ammunition for the various sides of the argument.

Douglas A. Irwin, a professor at Dartmouth College, is arguably the preeminent living historian of U.S. trade policy. His landmark 2017 book, Clashing over Commerce: A History of US Trade Policy, is considered the definitive account, meticulously documenting the political and economic forces that have shaped American protectionism and liberalization for over two centuries. His work is characterized by a deep dive into the data and a careful debunking of the myth that 19th-century protectionism was the key to America’s industrial success.

Paul Krugman, a Nobel laureate, has had a fascinating intellectual journey. After pioneering strategic trade theory, he has become one of the most forceful public defenders of free trade, arguing that the practical case against protectionism is overwhelming.

Pinelopi “Penny” Goldberg, a professor at Yale and former Chief Economist of the World Bank, is a leading figure in the empirical analysis of trade policy. Her data-driven work provided some of the most convincing evidence that the costs of the 2018 Trump tariffs were passed on to Americans.

Other key voices include David Autor of MIT, whose work on the “China shock” has forced a more honest conversation about the costs of trade, and Dani Rodrik of Harvard, who has long argued that “hyper-globalization” has gone too far and that countries should have more policy space to manage their integration into the global economy.

8. The Lighter Side of Levies: Curious Tariff Tales

For all its serious economic consequences, the history of tariffs is also littered with stories that are more comical than consequential. These anecdotes reveal the often-absurd lengths to which governments will go to protect a favored industry.

Perhaps the most famous of these is the “Chicken Tax.” In the early 1960s, a dispute over U.S. chicken exports to Europe led to a retaliatory 25% U.S. tariff on light trucks. Decades later, that single tariff still remains, profoundly shaping the American pickup truck market and leading to comical evasive maneuvers, such as Ford importing its Transit Connect vans with throwaway rear seats to classify them as passenger vehicles.

Another classic tale comes from the 19th-century trade disputes between Germany and Russia. To protect its own cattle farmers while not violating trade agreements with Switzerland, Germany crafted a special, lower tariff rate for “large dappled mountain cattle reared at a spot at least 300 meters above sea level and which have at least one month’s grazing at a spot at least 800 meters above sea level.” The only cattle that could meet this oddly specific description were, of course, from Switzerland.

In a more modern and nerdy example, the U.S. tariff code’s different rates for “dolls” and “toys” led to a federal lawsuit in 2003, Toy Biz, Inc. v. United States, in which the court had to decide if X-Men action figures were human “dolls” or non-human “toys.” The court sided with the toy company, ruling that the mutants were not human and therefore deserved the lower tariff rate.

9. Latest Perspectives: The World After the 2025 Tariff Shock

The tariff war unleashed in May 2025 did not just revive historical debates; it created a real-time economic laboratory, yielding immediate and often stark results. The initial months have provided a wealth of data, confirming some classical economic predictions while revealing new dynamics in the 21st-century global economy.

The Consumer Cost is Confirmed and Quantified: The most immediate and widely confirmed impact has been on U.S. consumers. Early analyses from institutions like the Yale Budget Lab and the Tax Foundation have been unequivocal: the cost of the new tariffs has been almost entirely passed through to American households and businesses. A July 2025 study from the Yale Budget Lab estimated that the tariffs would result in an average income loss of $2,400 per U.S. household in 2025 due to higher prices. The impact is regressive, with lower-income households bearing a disproportionately heavy burden relative to their income. The price hikes have been particularly acute for imported consumer goods, with the study noting short-run price increases of nearly 40% for apparel and shoes and over 12% for motor vehicles. This has fueled inflationary pressures, complicating the Federal Reserve’s policy decisions.

Accelerated Supply Chain Realignment: If the first Trump-era tariffs initiated a rethink of global supply chains, the 2025 tariffs have put that process into hyperdrive. The uncertainty and high costs have forced companies to accelerate their diversification away from China, a strategy now dubbed “de-risking” or “friend-shoring.” Reports from mid-2025 show companies like Apple fast-tracking plans to shift up to 20% of iPhone production to India and Vietnam. This rapid realignment is not a simple “reshoring” of jobs. As a study from supply chain experts at Michigan State University noted in mid-2025, the extreme uncertainty of the new tariff regime has forced firms to develop multiple, complex contingency plans, fundamentally shifting their focus from cost-efficiency to risk mitigation. Adding to this, PIIE senior fellow Mary Lovely has described the new tariff regime as creating a “slow-burn efficiency loss,” as American firms are now burdened with navigating a complex, country-by-country web of tariffs, disrupting decades of streamlined global production.

The Geopolitics of Retaliation: The international response has been swift, but also strategically nuanced. While countries have enacted retaliatory tariffs, many have also focused on strengthening trade ties elsewhere, effectively routing around the U.S. market. India’s response has been particularly notable. Faced with a 25% U.S. tariff and additional penalties, Delhi has held firm, refusing to concede on core domestic interests like agriculture and data localization. Simultaneously, it has accelerated trade negotiations with the European Union and the United Kingdom, signaling a broader strategy of reducing its dependency on any single trade partner. This reflects a new multipolar dynamic where countries are less willing to capitulate to unilateral pressure and are actively building alternative economic blocs.

Trade Diversion and New Economic Insights: The new trade war is not just destroying trade; it’s redirecting it. A July 2025 analysis from the European Central Bank (ECB) found that the escalating U.S.-China trade tensions are likely to divert a significant volume of Chinese exports toward the Eurozone. The ECB estimates that the Euro area could see imports from China rise by as much as 10% in 2026 as a direct result of U.S. tariffs. This “trade diversion” could lead to lower consumer prices in Europe but also poses a competitive challenge to European domestic producers. This insight underscores that the effects of a bilateral trade war are never truly bilateral. The consensus emerging from the initial data is that the 2025 tariffs are functioning as a broad tax on the U.S. economy. Summarizing the global fallout, a May 2025 study from the Centre for Economic Policy Research (CEPR) projected that the tariff war would cause global trade flows to contract by over 5% and trigger significant welfare losses, with the U.S. itself being among the most affected.

10. Foundational Research: Key Papers on Tariffs

The modern understanding of tariffs is built on a foundation of rigorous economic research. While the literature is vast, a few key papers stand out for their influence and clarity.

• “The Impact of the 2018 Trade War on U.S. Prices and Welfare” by Mary Amiti, Stephen J. Redding, and David E. Weinstein (NBER Working Paper No. 25672)

  This paper is arguably the definitive empirical analysis of the 2018 U.S. tariffs. Using detailed trade data, the authors found that the full cost of the tariffs was passed on to U.S. consumers and firms. They found no evidence that foreign exporters lowered their prices, debunking the claim that foreign countries would “pay” the tariff. The study concluded that the tariffs led to a substantial net welfare loss for the U.S. economy.

• “The China Syndrome: Local Labor Market Effects of Import Competition in the United States” by David H. Autor, David Dorn, and Gordon H. Hanson (American Economic Review, 2013)

  This seminal paper transformed the debate on globalization by documenting the severe, concentrated, and long-lasting negative effects of import competition from China on specific U.S. local labor markets. The authors showed that communities more exposed to the “China shock” experienced higher unemployment, lower labor force participation, and reduced wages, particularly in manufacturing. Their work highlighted that the adjustment costs of trade are far more painful and persistent than previously understood.

• Measuring the Costs of Protection in the United States by Gary Clyde Hufbauer and Kimberly Ann Elliott (Peterson Institute for International Economics, 1994)

  This classic PIIE study is famous for its direct and powerful method of quantifying the costs of protectionism. By analyzing 21 different protected industries, the authors calculated the annual cost to U.S. consumers for every job “saved” by tariffs and trade barriers. Their finding—that the cost to consumers often exceeded $100,000 per job, many times the actual worker’s salary—became a powerful and widely cited argument against protectionism.

• “Tariffs and Growth in Late Nineteenth Century America” by Douglas A. Irwin (NBER Working Paper No. 7639)

  In this paper, Douglas Irwin directly confronts the popular argument that high tariffs were responsible for America’s industrialization in the late 19th century. Through careful historical and statistical analysis, he concludes that while tariffs were high, they played a minimal role in the country’s overall economic growth. He argues that growth was primarily driven by other factors, such as capital accumulation and productivity growth in non-traded sectors, and that the tariffs likely imposed a net cost on the economy.

Conclusion

The tariff, then, is a tool of immense power and complexity. It can be a shield for nascent industries or a cudgel in a trade war. It can be a source of national pride or a driver of global depression. Its story is a microcosm of the larger story of globalization itself, a perpetual tug-of-war between the logic of economic efficiency and the passions of national identity. As the world once again grapples with the allure of the tariff wall, it would be wise to remember the lessons of its long, complicated, and often-peculiar past. The script for this play has been written many times before, and as the early results from the 2025 trade shock suggest, the final act is rarely as triumphant as its authors imagine.
