My former Mercatus Center colleague Walker Wright explains how trade promotes peace. Two slices:
While the liberal peace theory remains influential, a growing wave of empirical research over the last three decades suggests that markets may play a bigger role than the ballot box. This shift in consensus toward what’s known as the capitalist peace theory posits that trade openness and economic interdependence are among the primary forces that mitigate war. Of course, scholars continue to debate over how much trade and economic freedom contribute to peace. But liberal peace theorists now include economic interdependence as an essential element within the broader liberal peace project. Economic interdependence s “part of the glue that cements the ‘liberal peace’ together.” As trade has grown worldwide, so has peace.

Over two centuries ago, German philosopher Immanuel Kant wrote, “The spirit of trade cannot coexist with war, and sooner or later this spirit dominates every people. For among all those powers (or means) that belong to a nation, financial power may be the most reliable in forcing nations to pursue the noble cause of peace[.]” Others echoed this sentiment. “PEACE,” Montesquieu argued, “is the natural effect of trade.” In Rights of Man, American revolutionary Thomas Paine described commerce as “a pacific system, operating to unite mankind, by rendering nations, as well as individuals, useful to each other … If commerce were permitted to act to the universal extent it is capable of, it would extirpate the system of war, and produce a revolution in the uncivilized state of governments.”
These philosophers and revolutionaries were correct. In the end, trade steers us away from war and brutality and toward peaceful cooperation. If we care about a future that is richer, freer, and more humane, then keeping markets open and people connected through trade is one of the surest paths to a more peaceful world.
Here’s a short clip, from a talk that I gave for AIER this past Wednesday, on why trade reduces the chances of hot shooting wars.
Inu Manak and Allison Smith describe Trump’s trade ‘policy’ as “self-defeating” and as an “illusion of reciprocity.” Three slices:
But the Trump administration’s approach is not reciprocity at all. It is coercive unilateralism dressed up as reciprocity. The United States has pursued reciprocal trade for the past 90 years, but what Trump is doing breaks from this tradition. Under the threat of tariffs and, in some cases, territorial expansion, the administration has pressured U.S. trading partners to accept unbalanced trade concessions. Washington’s goals are to rebalance trade by tilting the playing field in favor of U.S. firms and producers, to force partners to pay for what Trump perceives as past unfairness, and to realign trade policy with foreign policy goals that preserve U.S. hegemony. Other countries are expected to give a lot but get little in return.
The United States, however, cannot remake the entire international trading system on its own. Any structural change to the international order requires others to buy in to the vision that is being sold. U.S. trading partners may be willing to try to appease Trump in the short term, but they do have other trading options—and they are already starting to pursue alternatives to the United States. Trump will need to offer them a few carrots along with using sticks if he wants these trade arrangements to last. Otherwise, the trust and order that the United States built through decades of careful trade compromises will quickly run out. An “America first” trade policy will leave America behind.
…..
Trump’s version of reciprocity has meant negotiating deals that are unlike traditional U.S. trade agreements. In line with his general ethos of moving fast and breaking things, the deals he has struck have bypassed Congress—even though it holds the constitutional authority to regulate commerce with foreign countries, including setting tariff rates. These agreements also lack neutral enforcement mechanisms, making them less durable and more likely to be seen by trading partners as nonbinding. Although a small number of deals resemble the form of typical trade agreements, with detailed commitments to abide by global trade norms such as regulatory transparency, most are loose frameworks that merely set up space for future dialogue. This means that it is not obvious what compliance looks like, leaving room for the United States to claim a deal was breached and demand retaliation.
The United States is not actually lowering tariffs in these trade deals. Instead, it is offering to reduce tariffs from punitive levels to new baseline rates that Trump set on so-called Liberation Day in April 2025. U.S. trading partners are being asked to give more access to their markets to U.S. firms and to accept more restrictions on their exports to the United States. Although the U.S. Supreme Court ruled that Trump’s emergency tariffs were unconstitutional, the administration is working to find alternate tariff mechanisms to form the basis for the agreements it struck before February 2026.
…..
As Washington abandons reciprocity for coercive unilateralism, the biggest victim may be the United States itself. The administration’s insistence on using tariffs as its primary trade tool will raise costs for U.S. consumers and businesses and antagonize its friends and allies. And despite the bluster from the White House, the strategy has clear limits. The cost of using economic coercion against friends is higher than the value of the new market access that can be won through the administration’s patchwork of deals. When trade deals are truly reciprocal, U.S. partners are willing to provide market access and align their policies with Washington at a relatively low cost. But a coercive approach erodes partners’ domestic support for cooperation with the United States and increases political friction.
The Trump administration’s trade agenda is not only asymmetric; it also fails to meet the moment. Countering China’s economic coercion requires a viable alternative that other countries can get behind. Yet Trump has largely wasted leverage on trading partners that were already willing to come to the table, including Japan, the United Kingdom, and Vietnam, and done little to convince some of the largest markets—Brazil, China, and India—to seriously negotiate. And the United States is losing leverage because its attempt to go it alone on trade has encouraged the rest of the world to cooperate more, not less, giving countries more alternatives to Washington.
GMU Econ alum David Hebert decries the Trump administration’s “endless search for emergency tariff authority.” A slice:
The legal foundation for taxing every import into the US has now rested, at various points in the past year, on a 1977 emergency powers law, a 1974 statute designed for a monetary system that no longer exists, and — if the administration’s next move is what trade lawyers expect — a Depression-era provision that has never once been used to impose actual tariffs in almost a century. At some point, running out of legal justifications is a signal worth heeding.
Reason‘s Eric Boehm continues to write insightfully about Trump’s tariffs punitive taxes on Americans’ purchases of imports. A slice:
Simply put: you can’t make tires without rubber, and it is impossible to buy rubber that isn’t imported—because rubber trees do not grow in the United States. (Unless you count the one at the U.S. Botanic Garden in D.C., but that’s probably not going to produce enough rubber to supply Goodyear’s needs.)
That means American tire companies import rubber from places like Thailand, which has a climate well-suited to growing rubber trees and produces a lot more rubber than its domestic industries can consume. Naturally, Thailand exports a lot of that excess rubber to other parts of the world, including the United States.
However, the Trump administration sees other countries with a surplus of rubber production as a threat to be targeted with tariffs. In March, the Office of the U.S. Trade Representative claimed that Thailand’s “trade surplus in sectors such as…rubber” was grounds for slapping higher tariffs on those imports.
That makes very little economic sense.
“Tariffs on natural rubber, no matter how high, won’t bring rubber-tree plantation jobs to Minnesota or North Carolina, but will raise costs and reduce sales for every U.S. manufacturer of airplane and truck tires, vibration dampers in bridges, specialized medical equipment, and so on,” wrote Ed Gresser, a former assistant U.S. Trade Representative, in a prescient piece published earlier this week by the Progressive Policy Institute, where he is a vice president.
George Will writes about Rep. Don Bacon (R-NE), one of the relatively few serious legislators in today’s Congress; Bacon has had enough and is not seeking re-election. A slice:
In the making of laws, Bacon has occasionally made himself a nuisance to people who deserve to be tormented. As he did in February.
The Republican-controlled House was doing its job as it miserably understands this: tugging its forelock and doing the president’s bidding. The president’s confidence in his arguments for his tariffs can be gauged by his eagerness to squelch debate about them.
The House Republican leadership was determined to pass a gag rule to prevent a debate on ending the “emergency” that supposedly justifies the tariffs. The GOP leadership could not afford to lose even three Republicans. Bacon was one of three recalcitrant.
The White House tried to buy Bacon’s compliance by promising tariff and other special benefits for three businesses in his district. Bacon thought the legality of this was dubious, and its unseemliness obvious.
During hours of pressure, a member of his party’s leadership said, “Don, look me in the eye before you vote ‘no.’” Bacon said: “I did before the vote.” The gag rule having failed, the next day the ungagged House rebuked Trump for his tariffs against Canada.
Raymond Niles makes clear that so-called “perfect competition” is highly imperfect; we denizens of market economies ought to give thanks daily that we are at no risk of experiencing it in practice. [DBx: A few years ago, I wrote similarly.]
