January 19, 2018 — President Trump and the Republicans succeeded last month in passing their big tax cut. It may not have many of the desirable attributes of true tax reform (equity, efficiency, bi-partisanship, revenue-neutrality, or cyclical timing); but it is major legislation, as promised. What about that other major Trump promise, to cut the US trade deficit? The tax cut is virtually certain to raise the budget deficit and in turn to raise – not lower – the current account deficit. Call it the Return of the Infamous Twin Deficits. As when Ronald Reagan cut taxes in 1981-83 or when George W. Bush cut taxes in 2001 and 2003.
