Winter is the time for gifts, carols, for meeting with friends, stories read close to the fireplace, memories, for boiled wine with cinnamon and warm sponge cake. I recommend you to read these three stories woven around the words of famous economists from centuries ago, which, even if they are the product of the imagination, describe phenomena that have had and continue to have a great influence on people. I hope that what you will read below will pleasantly remind you about the stories that you have read in childhood around the Christmas tree.
