Gresham's law
About this model
Thomas Gresham, 1558. When the metal in a clipped coin is worth less than the metal in a good coin, people hoard the good coins and spend the bad ones, so good coins vanish from circulation. A teaching model: it keeps only this core loop and leaves out everything else a real economy has.
