If Trump governs in accordance with the campaign that got him elected, we can expect market scares in the United States and around the world, as well as potentially significant economic damage.
A radical populist Trump would scrap the Trans-Pacific Partnership (TPP), repeal the North American Free Trade Agreement (NAFTA), and impose high tariffs on Chinese imports. He would also build his promised US-Mexico border wall; deport millions of undocumented workers; restrict H1B visas for the skilled workers needed in the tech sector; and fully repeal the Affordable Care Act (Obamacare), which would leave millions of people without health insurance.
Overall, a radical Trump would significantly increase the US budget deficit. He would sharply reduce income taxes on corporations and wealthy individuals. And while he would broaden the tax base, increase the carried-interest tax, and encourage companies to repatriate foreign profits, his plan would not be revenue-neutral. He would increase military and public-sector spending in areas such as infrastructure, and his tax cuts for the rich would reduce government revenue by $9 trillion over a decade.
A radical Trump would also drastically change the current monetary-policy approach – first by replacing US Federal Reserve Chair Janet Yellen with a monetarist hawk, and then by filling current and upcoming Fed Board vacancies with more of the same. Moreover, he would repeal what he could of the 2010 Dodd-Frank financial reforms; gut the Consumer Financial Protection Bureau; cut alternative-energy subsidies and environmental regulations; and slash any other regulations that supposedly hurt big business.
Finally, a radical Trump’s foreign policy would destabilize America’s alliances and escalate tensions with rivals. His protectionist stance could incite a global trade war, and his insistence that allies pay for their own defense could lead to dangerous nuclear proliferation, while diminishing American leadership on the world stage.
But there is good reason to expect that he will govern very differently.
Once in office, Trump will throw symbolic red meat to his supporters while reverting to the traditional supply-side, trickle-down economic policies that Republicans have favored for decades.
