Figure 8.15: A Shift in the S-Shaped PDC
This figure illustrates how a housing market bust can be triggered by a change in expectations. It depicts an S-shaped Price Dynamics Curve (PDC) shifting downwards to a new position (PDC') because of a widespread belief that high prices are unsustainable. This shift moves the market from an initial high-price stable equilibrium (D) to a new, lower stable equilibrium (D'), while also establishing a new, lower tipping point (T').

Increased Risk of Market Collapse from a Downward PDC Shift
Market Collapse to a Single Low-Price Equilibrium via a Major Downward PDC Shift
A housing market is in a stable, high-price equilibrium, as described by a model that relates current prices to expected future prices (the Price Dynamics Curve). Suddenly, a wave of negative economic forecasts leads to a widespread belief among buyers and sellers that future prices will be significantly lower than previously anticipated. According to this model, how does this change in sentiment directly trigger a market downturn?

The Role of Expectations in Housing Market Downturns
A housing market, initially at a high-price stable equilibrium, experiences a sudden, widespread shift in sentiment towards pessimism about future values. According to the model where a curve represents the relationship between current and expected future prices, arrange the following events into the correct causal sequence that results in a market bust.
Explaining a Housing Market Bust Mechanism
In a housing market model where a curve represents the relationship between current and expected future prices, a widespread shift to pessimistic expectations will cause the market to move along the existing curve to a lower price point, without the curve itself shifting.
A housing market is modeled using a curve that relates current prices to expected future prices. In the context of a market bust triggered by a change in sentiment, match each component of the model's dynamics with its correct description.
A housing market is described by a model featuring an S-shaped curve that relates current prices to expected future prices. This model has two stable equilibria (one high-price, one low-price) and one unstable tipping point. If the market is initially at the high-price stable equilibrium and a widespread wave of pessimism about future values causes the entire curve to shift downwards, what is the most likely consequence for the market's underlying structure?
A housing market, which had been stable for years at a high price level, experiences a severe and prolonged crash. Following an initial sharp drop, prices fail to rebound and continue to decline until they stabilize at a very low level, showing no tendency to return to their previous highs. In a model that uses an S-shaped curve to represent the relationship between current prices and expected future prices, which of the following best explains this specific outcome?
