Stable Equilibrium and Negative Feedback in Price Dynamics
A market equilibrium is considered stable if, following a shock that displaces the price, market forces naturally guide it back to the original equilibrium level. In a dynamic price adjustment model, this stability is represented by a Price Dynamics Curve (PDC) that is flatter than the 45-degree line. This slope ensures that any deviation from the equilibrium price initiates a process of negative feedback, where price adjustments in subsequent periods progressively correct the initial displacement and restore market equilibrium.

Environmental Dynamics Curve (EDC)
A market's price dynamics are described by a curve that plots the price in the next period () as a function of the price in the current period (). This curve intersects the 45-degree line (where ) at two points, representing two potential price equilibria: Point A and Point B. At Point A, the slope of the curve is 0.5. At Point B, the slope of the curve is 1.5. Which statement correctly analyzes the stability of these two equilibria?

Figure 8.11: Dampened Price Shock and Stable Equilibrium
A market for a particular good has a long-run equilibrium price of $50 per unit. A sudden, temporary shortage causes the price to spike to $70 in one period. In the following periods, the price is observed to be $60, then $55, then $52.50. Which of the following statements best analyzes this market's behavior?

Contrasting Market Stability and Instability
If a market's price dynamics are represented by a curve that is steeper than the 45-degree line, any small deviation from the equilibrium price will trigger a self-correcting process that returns the price to its original level.
Match each market characteristic or event with its correct implication regarding price stability.
A market is in a stable equilibrium when a temporary supply disruption causes the price to jump above its long-run level. Arrange the following events in the correct chronological order to show how negative feedback restores the market to its original equilibrium.
For a market equilibrium to be considered stable, any price deviation must trigger a corrective process. This is represented graphically by a price dynamics curve that is flatter than the 45-degree line, which ensures that ______ feedback will guide the price back towards its initial level.
Analyzing Price Dynamics with a Linear Model
In a particular market, the long-run equilibrium price for a product is $100. Market analysts have determined that after a price deviation, the price in the next period adjusts to close half the gap between the previous period's price and the equilibrium price. For example, if the price were $110, the gap is $10, so the price would fall by $5 to $105 in the next period.
Suppose a temporary supply disruption causes the price to jump to $140. Based on the described adjustment process, what will the price be in the subsequent period, and what does this indicate about the market's equilibrium?
