"Trump's policies reflect a transformation of the global trade and capital regime that had already started. One way or another, a dramatic change of some kind was necessary to address imbalances in the global economy that have been decades in the making. Current trade tensions are the result of a disconnect between the needs of individual economies and the needs of the global system. Although the global system benefits from rising wages, which push up demand for producers everywhere, tensions arise when individual countries can grow more quickly by boosting their manufacturing sectors at the expense of wage growth—for example, by directly and indirectly suppressing growth in household income relative to growth in worker productivity. The result is a global trading system in which, to their collective detriment, countries compete by keeping wages down.
The tariff regime Trump announced earlier this month is unlikely to solve this problem. To be effective, American trade policy must either reverse the savings imbalance in the rest of the world, or it must limit Washington’s role in accommodating it. Bilateral tariffs do neither.
But because something must replace the current system, policymakers would be wise to start crafting a sensible alternative. The best outcome would be a new global trade agreement among economies that commit to managing their domestic economic imbalances, rather than externalizing them in the form of trade surpluses. The result would be a customs union like the one proposed by the economist John Maynard Keynes at the Bretton Woods conference in 1944. Parties to this agreement would be required to roughly balance their exports and imports while restricting trade surpluses from countries outside the trade agreement. Such a union could gradually expand to the entire world, leading to both higher global wages and better economic growth."
