The high contact principle as a sufficiency condition for optimal stopping. (English) Zbl 0783.90019

Stochastic models and option values. Applications to resources, environment and investment problems, Pap. Conf., Loen/Norway 1989, Contrib. Econ. Anal. 200, 187-208 (1991).
The high contact principle is essentially a first order condition in the optimization of the stopping time. The typical application of this principle in economics is the starting and stopping of resource extraction. The purpose of the paper is to show that under certain conditions the high contact property is also sufficient for the solution of the optimal stopping problem. In order to derive this result in the multidimensional case the Dynkin formula is generalized using a Green function.
