Earlier today, in an open letter to President Donald Trump, we joined with more than 150 economists from universities, think tanks, and businesses across the country to urge the president to confront one of the most damaging and least-discussed obstacles to global prosperity: international anti-competitive market distortions (ACMDs).

For decades, trade debates have been dominated by tariffs—the visible, headline-grabbing taxes that nations impose on imports and, occasionally, on exports. Tariffs are easy to measure. Yet they are only the tip of the iceberg. Beneath them lies a complex and far more damaging set of distortions that quietly undermine competition and economic growth: discriminatory regulations, state subsidies, and other “protections” that favor domestic champions over foreign competitors.

ACMDs invariably sap productivity, distort the economy, and destroy wealth.

Our open letter to President Trump, printed below in its entirety and signed by some of the country’s most prominent economic theorists and practitioners, asks the president to use this moment and the leverage of U.S. trade policy to lead a global reset. The Trump administration has rightly highlighted the shortcomings of America’s trade relationships. The problem is real. But the true injustice lies not just in tariff schedules but in the deeper, structural distortions that prevent open and fair competition.

Over the past several decades, the international trading system has generally succeeded in reducing tariffs across the board. What it has not done is meaningfully address non-tariff barriers, including regulatory manipulation. As a result, the most consequential obstacles to faster economic growth today are not at the border, but behind it.

When a government shields its state-owned enterprises with veiled subsidies or tilts domestic regulation to crowd out foreign firms, it is engaging in protectionism by another name. Economists increasingly agree that the impact of these non-tariff distortions likely exceeds that of tariffs several times over.

President Trump’s instincts—to question complacent trade orthodoxy and demand reciprocity—have opened a rare window of opportunity. Whether one agrees with his particular approach, the administration’s willingness to confront entrenched interests and rethink policy from first principles is welcome.

What’s needed now is a clear framework: U.S. trade agreements should be evaluated and negotiated on the basis of how effectively they reduce all anti-competitive market distortions, not just tariff barriers.

A strategy focused on ACMDs would produce enormous dividends. Even modest reductions in these distortions would lift U.S. and global per capita GDP.

A recent study by the Competere Foundation for the independent Growth Commission on which we both sit suggests that if countries want to spur economic growth, they would be wise to 1) dismantle laws and regulations that distort domestic competition and 2) abolish tariff and non-tariff barriers that distort international competition. The Competere Foundation study estimates that, if the United States were to do these things, U.S. per capita GDP would jump by an extra 31 percent over ten years.

Fortunately, the United States is uniquely positioned to lead this effort. American markets remain among the world’s most open and competitive. That gives President Trump the leverage he needs to force change on America’s reluctant trading partners.

A trade policy centered on dismantling global market distortions would align perfectly with America’s comparative strengths—rule of law, transparency, fervent entrepreneurism, and never-ending innovation. It would also place the U.S. at the moral center of a new pro-growth international consensus.

This is not a partisan appeal. It is a call to return trade policy to its first principles: fair competition, open markets, and the creation of wealth through voluntary exchange. The U.S. can and should use its diplomatic and economic leverage to encourage its trading partners to do the same.

Mr. President, tear down these economic distortions! The wealth of nations—and the prosperity of billions—depends on it.

Dear President Trump,

We the undersigned write to ask the US government to tear down international anti-competitive market distortions (ACMDs). Your administration's policy provides an opportunity for a reset to deal not only with tariff barriers but also with all market distortions that damage the competitive process and thus destroy wealth. Regrettably, these ACMDs, which include both traditional tariff and non-tariff barriers as well as regulatory matters that distort ordinary market competition and lack of property rights protection, have not been well addressed in the international trading system or by major trading countries in the past thirty years. These issues are major impediments to economic growth, and indeed recent economic models suggest that the costs of non-tariff ACMDs may be considerably more impactful than conventional border barriers.

The Trump administration is right to highlight the problem with its proposed trade realignment. While many of us differ on the medicine we would use to treat the problem, we think that a framework that measures the US’s trade agreements with other countries on the basis of their success in lowering these ACMDs should ground US trade policy actions at this time. A systematic reduction of ACMDs across the board in all countries would be a significant boost to U.S. and global GDP per capita, giving opportunity and hope to billions.
