In a simple supply and demand diagram, such as Fig. 7 General Equilibrium Theory 41 is above the equilibrium, we expect excess supply to create pressures that will lower the price and move the market back to P* and Q*. And if the price were too low, there would be excess demand creating pressure on the price to rise. In either case, once the process had worked itself out, we would be at the same equilibrium, P* and Q*. The equilibrium itself doesn’t depend on where we approach it from. That means we don’t need to know what the initial situation in the market is in order to pin down this equilibrium.
As you may suspect, a lot of disutility attributable to production in most economies is uncompensated, and for this reason market costs understate the true human costs at stake.
