Optimal harvest rules and preharvest valuation procedures are derived for biological assets with stochastic size-dependent growth in a stochastic price environment. These issues are analyzed as continuous-time optimal stopping problems. Both the "single-rotation" and "ongoing-rotations" problems...

Some applications of optimal stopping rules in the analysis of resource economic problems are surveyed. The conceptual foundation for the approach stems from the dual roles of uncertainty and irreversibility in these problems. A stochastic adaptation of Wicksell's "tree-cutting" paradigm is...
