The ongoing advance of globalisation has created a genuine need for international tax reforms. This column explores potential reforms and their likely effects, using a model with flexible prices. Residence-based income taxation is shown to have welfare advantages over source-based taxation, though at the cost of a larger trade deficit. Non-transitory border taxes are shown to be ineffective at reducing this deficit.

President Trump’s doctrine on trade represents a radical break with previous US policy. This column, the first of two examining the Trump doctrine, argues that he embraces fallacies as facts, and that the efforts to reform tax are flawed and will make tax law more complex. If enacted, the Auerbach-Ryan Tax Plan would be a mechanism by which the US government collects taxes to benefit rich citizens at the expense of the country's trading partners.

A border tax adjustment from origin-based taxation to destination-based taxation is under consideration for corporate profit tax in the US. This column investigates the implications of such an adjustment for the nominal exchange rate, assuming the real equilibrium of the economy is unchanged. While conventional wisdom is that the currency of the country implementing the adjustment will appreciate by a percentage equal to the VAT or corporate profit tax rate, a depreciation of the same magnitude is just as likely.
