Yesterday evening, I visited an old friend, who had a bright nephew, around 19 years old, over. During the discussion, which somehow turned to exchange rates, he asked, "what determines the exchange rate between currency X and currency Y anyways?" It was a great educational moment, always made simpler by real-world examples, which I love. After all, the great insight of economics is that it is not high-level theory that really makes up an economy, but just the sum of billions or trillions of decisions in the real world.
