For a general class of risk models, the dividends-penalty identity is derived by
probabilistic reasoning. This identity is the key for understanding and determining
the optimal dividend barrier, which maximizes the difference between the
expected present value of all dividends until ruin and the expected discounted
value of a penalty at ruin (which is typically a function of the deficit at ruin).
As an illustration, the optimal barrier is calculated in two classical models, for
different penalty functions and a variety of parameter values.
