We propose an adaptation of Hartwick’s investment rule to models with population growth and show that following is equivalent a time-invariant real per capita net national product. In the so-called DHSS model capital accumulation resource depletion proposed equates capital, dilution effect growth, value resource, gross effect. investigate why this asymmetry arises by analyzing general multiple ...

The objective is to find the optimal pricing, replenishment, and preservation t...
