The Role of Feedback in Equilibrium Stability
The stability of an equilibrium is determined by the type of feedback that dominates in its vicinity. Negative feedback stabilizes an equilibrium by counteracting any movement away from it, making the equilibrium stable. Conversely, positive feedback destabilizes an equilibrium by amplifying any disturbance, pushing the system further away and making the equilibrium unstable.

Consider a market where the price in the next period is a function of the price in the current period. This relationship is shown by a Price Dynamics Curve (PDC) plotted against a 45-degree line, where the price is constant. The PDC intersects the 45-degree line at two points: Point A (a lower price) and Point B (a higher price). At Point A, the PDC is steeper than the 45-degree line. At Point B, the PDC is flatter than the 45-degree line. Which of the following statements correctly analyzes these two equilibrium points?

Imagine a local agricultural market where an unexpected bumper crop of corn causes the price to fall significantly below its usual level. In response, a government program automatically kicks in, buying up the excess corn to store it. This action reduces the available supply on the market, causing the price to rise back toward its original level. Which of the following statements best analyzes the dynamic created by the government program?

Match each economic scenario with the type of feedback loop it describes and its resulting effect on equilibrium.
Consider a market for a new technology. As the number of users increases, the value of the technology for each user also increases, which in turn attracts even more users. This dynamic is an example of a negative feedback mechanism that helps maintain the market's initial equilibrium.
A market is in a stable equilibrium when a temporary external shock causes the price to rise significantly above the equilibrium level. Arrange the following events in the correct chronological sequence to illustrate how a negative feedback mechanism restores the market to its equilibrium.
When a country's central bank raises interest rates to curb inflation, the higher rates discourage borrowing and spending, which in turn reduces inflationary pressure. This mechanism, where the initial action triggers a response that counteracts the original problem, is an example of a ____ feedback loop.
