If the chicken farmer knows that some time will pass before he must redeem his notes with actual chickens, or that some if his notes will circulate forever and never come in for redemption, he may be tempted to issue more notes than he has in actual chickens, thinking that he will be able to cover all the notes by the time they come back to him. Temptation now gets the best of the chicken farmer.
