More on Protectionism

Paul Krugman Blog - NYTimes.com

First of all: my piece was NOT an endorsement of protectionism -- it was an explanation that there is an economic case for it, but also that there is a strong political economy case (which I consider dominant) against acting on that economic case. It was, in short, an attempt to be intellectually honest.
Second, Nick Rowe argues that under flexible exchange rates the economic case goes away. His argument is based on the proposition that since interest rates are fixed under a liquidity trap, capital flows are fixed, and the exchange rate will adjust to offset any change in the trade balance.
