Figure 8.14: An S-Shaped PDC with Two Stable Equilibria
This figure provides a visual representation of a market with multiple equilibria by plotting the price in period t () against the price in period t+1 (). It features an S-shaped Price Dynamics Curve (PDC) that intersects the 45-degree 'price unchanged' line at three distinct points. Two of these points, C (at a low price) and D (at a high price), are stable equilibria. The third point, T, located at a middle price level, is an unstable equilibrium that functions as a tipping point. Any small price deviation from T is amplified, pushing the market toward either the low-price stable equilibrium at C or the high-price stable equilibrium at D.

Figure 8.14: An S-Shaped PDC with Two Stable Equilibria
Consider a market for a niche product that for many years had a stable price of around $50. Following a sudden surge in popularity, the price jumped to $500 and has remained stable at this new, higher level for a considerable time. Market analysts observe that if the price were to dip below a critical threshold of approximately $200 due to a temporary shock, it would not recover to $500 but would instead rapidly fall all the way back to the original $50 price level. Based on this dynamic, what is the most accurate description of this market's structure?
Interpreting Market Behavior
Market Price Stability and Tipping Points
In a market modeled by an S-shaped price dynamics curve, if the price is slightly perturbed from the middle, unstable equilibrium point, self-correcting market forces will tend to restore the price to that same unstable equilibrium.
The Role of the Tipping Point in Market Dynamics
A market is described by a model with three distinct price equilibrium points: a low-price point, a middle-price point, and a high-price point. Match each type of equilibrium point with its correct description of market behavior.
A particular market is known to have two stable price levels, $30 and $120. It also has a critical 'tipping point' price of $80, which is an unstable equilibrium. If a temporary supply chain disruption causes the price to spike to $85, the price is expected to eventually settle at $____ after the disruption ends.
A market is known to have two stable price levels ($20 and $100) and one unstable 'tipping point' price ($60). Imagine a temporary external event pushes the current market price to $55. Arrange the following descriptions in the correct chronological order to illustrate how the market price will adjust over time.

Effect of Large Shocks on a Stable Equilibrium
A market for a new technology exhibits the following behavior: if the price is very high, consumer expectations of future price drops cause demand to fall, pushing the price down toward a moderate level. If the price is very low, high demand and limited supply push the price up, also toward that same moderate level. However, there exists a specific, intermediate price point where the market is precariously balanced. If the price deviates even slightly below this intermediate point, it triggers a rapid, self-reinforcing price collapse to the very low level. Based on this description, how should the dynamic at this specific, intermediate price point be characterized?

Analyzing System Dynamics
A system that is precisely at a tipping point will return to that same point after experiencing a minor shock, as the forces pushing it in either direction are perfectly balanced.
Match each description of a system's behavior with the dynamic it best represents.
Fishery Collapse Scenario
A system is subjected to a small, external shock. Which of the following subsequent behaviors would indicate that the system's initial state was a tipping point?
A financial market for a specific asset is initially in a state of fragile stability. A series of events unfolds, leading to a rapid and dramatic price collapse. Arrange the following stages of this process in the correct chronological order to illustrate the dynamics of a system moving past a critical threshold.
