A few economic riddles or puzzling ideas:
- EconomicRiddleOne: Creation of value in building a house.
- EconomicRiddleTwo: Creation of value in starting a company.
- CreationOfMoney: How money is created in modern banking systems.
Each of these is puzzling only so long as one conflates money, be it cash or bank balance, with value, thus giving money a special status. Modern finance works as it does exactly by treating currencies as commodities with market values, just like anything else that anyone trades.
