Numerical simulations do confirm the role of prices in decreasing
the amplitude of oscillations and in reducing resource depletion
as long as the equilibrium production is in the region where the prices are
decreasing with production, 
when the demand is large
with respect to production
(see figure 9 and figure 14). When the
equilibrium demand is small compared to
production and when the prices are maintained by the government
or another institution such as a producers organization,
oscillations and resource depletion are of course little reduced
(see figure 9).
