Comparative Statics
Comparative statics is the economic method used to analyze how a market's equilibrium price and quantity are affected by a change in an external factor. [1, 2, 3, 5] To conduct this analysis, demand or supply shocks are modeled mathematically by introducing parameters—representing factors other than price—into the supply and demand equations. [7] For further reading on the topic, Section 15.2 and the beginning of Section 15.3 of 'Mathematics for Economists: An Introductory Textbook' by Pemberton and Rau are recommended.

Market Analysis of a Technological Change
Suppose that in the market for avocados, observers note that the equilibrium price has risen while the equilibrium quantity has fallen. Which of the following events, occurring on its own, could explain this specific combination of changes?
Analyzing a Market Shock
Match each market event with its most likely impact on the equilibrium price (P) and equilibrium quantity (Q) in the specified market, assuming all other factors remain constant.
Analyzing Simultaneous Market Shocks
True or False: If a new health study is published that convincingly demonstrates major health benefits from eating apples, the immediate effect in the apple market will be an increase in the equilibrium price and a decrease in the equilibrium quantity.
A severe and unexpected frost damages a large portion of the world's coffee bean crop. Arrange the following market events in the correct chronological order to describe how the market for coffee beans adjusts to a new equilibrium.

Consider the market for new houses. In a single year, two significant events occur simultaneously: (1) the price of lumber and other essential building materials increases sharply, and (2) interest rates for home loans decrease, making it easier for people to borrow money to buy a house. Given only this information, what is the definite outcome on the equilibrium price and quantity of new houses?

Consider the market for avocados, which is initially in a stable state where the amount produced equals the amount consumers want to buy at the going price. A new, widely publicized scientific study finds that daily avocado consumption significantly improves cardiovascular health. By comparing the market's initial stable state to the new one that will emerge after this news, what is the most likely outcome?

Analysis of Simultaneous Market Changes
In the market for cotton, observers note that over the past year, the equilibrium price has risen while the equilibrium quantity traded has fallen. This outcome is consistent with a significant increase in consumer preference for cotton clothing.
Suppose that in the market for a specific good, observers note that over a short period, the price at which the good is sold has decreased, while the total quantity of the good bought and sold has increased. Which of the following single events could explain this specific combination of outcomes?
