Final answer:
Economic forces such as self-adjustment mechanisms and government interventions, particularly as proposed by Keynesian macroeconomics, work to bring the economy back to general equilibrium through adjustments in aggregate demand.
Step-by-step explanation:
The economic forces that act to bring the economy back to general equilibrium include self-adjustment mechanisms, which involve market forces correcting themselves without external intervention. For example, if a firm produces a product that no one wants to buy or at a higher cost than competitors, it will suffer losses and may go out of business, demonstrating a self-correcting mechanism in the marketplace. On the other hand, Keynesian macroeconomics proposes that government interventions are necessary to stabilize the economy, suggesting that increased aggregate demand through expansionary fiscal policy or decreased demand through contractionary policy can help achieve general equilibrium.
