The Dynamics of Market Instability
Imagine a market where a small, unexpected increase in price leads to an even larger price increase in the following period, which in turn causes a still larger increase in the period after that. Analyze the underlying mechanism driving this escalating price movement. In your response, explain the role of the relationship between the price in one period and the next, and describe the type of feedback loop that characterizes this market behavior.

Analyzing Market Stability
Consider a market where the price in the next period is determined by the price in the current period. The relationship is such that for every $1 increase in the current price above its equilibrium level, the price in the next period increases by $1.20. If the price is currently 5% above its equilibrium level, what is the most likely outcome for the price in the subsequent periods, assuming no other market changes?
Consider a market where the price is at an unstable equilibrium. If a minor, temporary supply surplus causes the price to fall slightly below this equilibrium point, the market's internal dynamics will cause the price to self-correct and return to the original equilibrium level.
The Mechanics of Price Instability
Match each description of a market's price adjustment process with its corresponding characteristic or outcome.
The Dynamics of Market Instability
In a market characterized by an unstable equilibrium, a positive feedback mechanism ensures that any initial price deviation from the equilibrium level will cause a subsequent price change that is ______ in magnitude than the initial deviation.
A market for a specific asset is at an unstable equilibrium. A sudden, small increase in demand causes the price to rise slightly. Arrange the following events in the logical sequence that describes the resulting positive feedback loop.
Imagine a market where the price in one period determines the price in the next. This relationship is plotted on a graph with the current period's price on the horizontal axis and the next period's price on the vertical axis. A 45-degree line on this graph represents a constant price. In this specific market, the curve showing the price relationship is steeper than the 45-degree line. If a small, temporary event causes the price to move slightly away from the point where the curve and the 45-degree line intersect, what is the most likely outcome?
