4. 2. Economically Optimal Values and Decisions in Iranian Forest Management

   Author : Soleiman Mohammadi Limaei; Peter Lohmander; Sjur Didrik Flåm; Swedish University of Agricultural Sciences; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Iranian Caspian forests; stumpage price; growth function; stochastic dynamic programming; dynamic game theory; Nash equilibrium;
