Here’s a letter to the New York Times:
While Jared Bernstein is correct that the dollar’s role as the international reserve currency increases the U.S trade deficit, his analysis of the consequences of a high global demand for U.S. dollars is a jumble of confusions (“Dethrone ‘King Dollar,’“ Aug. 28).
Most notably, Mr. Bernstein argues that countries, such as the U.S., that run trade deficits simultaneously suffer excess aggregate demand (“trade-deficit countries must absorb those excess [global] savings to finance their excess consumption or investment”) and deficient aggregate demand (“a result of this dance [of foreigners accumulating dollars], as seen throughout the tepid recovery from the Great Recession, is insufficient domestic demand in America’s own labor market”).
A trade deficit might either increase or decrease a country’s aggregate demand (or do neither) but, contrary to Mr. Bernstein’s muddled account, it cannot possibly do both. Alas, Mr. Bernstein’s confusion on this point reflects a more widespread and popular misunderstanding of trade deficits.

Many other flaws infect Bernstein’s op-ed – ones that, if I have time later today or tomorrow, I’ll point out.
