Abstract: Models are metaphors that explain the world we don’t understand in terms of worlds we do.
They are merely analogies, provide partial insight, stand on someone else’s feet.
Theories stand on their own feet, and rely on no analogies.
Models tell you what something is more or less like; theories try to tell you what something is.
Financial models are not theories; they are analogies, idealizations that always sweep dirt under the rug, and good models and good modelers have an obligation to make the dirt explicit.
