International economics and friends
The Impossible Trinity (also known as the Inconsistent Trinity, Triangle of Impossibility or Unholy Trinity) is the Trilemma in international economics suggesting it is impossible to have all three of the following at the same time:
- A fixed exchange rate.
- Free capital movement (absence of capital controls).
- An independent monetary policy.
I have a similar theory about friends and:
- Helping you move.
- Driving you to the airport.
- Remembering your birthday.
You can only have two. And, in this new context, aren’t you glad I don’t care at all when you were born?
