Abstract
A simple analytic model is presented which exhibits a critical behavior in black hole formation, namely, the collapse of a thin shell coupled with an outgoing null fluid. It is seen that the critical behavior is caused by the gravitational nonlinearity near the event horizon. We calculate the value of the critical exponent analytically and find that it is very dependent on the coupling constants of the system.
