Query: The Deterministic and Stochastic Shallow Lake Problem   We study the welfare function of the deterministic and stochastic shallow
lake problem. We show that the welfare function is the viscosity solution of
the associated Bellman equation, we establish several properties including its
asymptotic behaviour at infinity and we present a convergent monotone numerical
scheme.
