Scott Sumner has some questions on the border tax adjustment

Martin Feldstein had a recent piece in the WSJ that defended the idea of a border tax adjustment, which would be a part of the proposed corporate tax reform. He points out that if imports were no longer deductible, and exports received a subsidy, then the border adjustment would not distort trade. Rather the effect would be exactly offset by a 25% appreciation of the dollar. I certainly understand that this would be true of a perfect across-the-board border tax system. But is that what we will have?

1. Will the subsidy apply to service exports? (Recall that services are a huge strength of the US trade sector.) Let’s take Disney World, which makes lots of money exporting services to European, Canadian, Asian and Latin American tourists visiting Orlando. Exactly how will Disney determine the amount of export subsidy it gets? Do they ask each tourist what country they are from, every time they buy a Coke? That seems far fetched—what am I missing? If Disney doesn’t get the export subsidy, then the 25% dollar appreciation would hammer them, and indeed the entire US service export sector.

2. What about all those corporate earnings that are supposed to be repatriated? (And future earnings as well.) If the dollar appreciates by 25%, then doesn’t this hurt multinationals? Or am I missing something?

Update: It just occurred to me that corporate cash stuffed overseas is probably held in dollars. But future overseas earnings may still be in local currency.

Keep in mind that the prediction of 25% dollar appreciation is from the supporters of the plan, like Martin Feldstein. If you did this sort of adjustment without any dollar appreciation, the impact would be devastating on companies like Walmart. Given the Fed’s 2% inflation target, how could they pass along a (effective) 25% tariff on almost everything they sell?

There are other points of value at the link.  I agree with Scott’s most general claim that the case for this tax has not yet been made.
