John loves economics, and we are going to give him a present!
He is going to get a book by a Nobel laureate in economics—Professor Paul Milgrom (you can click his name to open his Wikipedia page). Professor Milgrom has agreed to help with our study.
John has already read some of his work and told us he has great admiration for him.
The book comes with a handwritten note. But here is the twist! We have two copies of this book. One with an original note from the famous author (Professor Milgrom), and one with a fake note written by someone excellent at copying the professor's handwriting.
John will receive one copy, either the one with the original handwritten note or the one with the fake one. We will return the copy that we do not give to John back to Professor Milgrom.
John cannot tell which copy he received unless we tell him. Professor Milgrom himself could not tell which is which!
John has agreed to all of this. For example, he knows that the book he receives may have the original note or the fake one.
