I just returned from a trip to South Korea. Today, to prepare for the next trip, I took my jacket to the dry cleaners. Turning the pockets out, I discovered a substantial number of South Korean won. The transaction costs of exchanging the won for dollars are now very high. I will keep the won as souvenirs.
Question: What are the consequences of my decision for the South Korean economy? Answer in the style of a well-known economist. What would Scott Sumner say? (almost too easy!) What about Keynes? Krugman? Cowen? Prescott?
