The demand for cars is an example of unit demand. A car is an asset because it is a durable good that can be resold. Gasoline and insurance are two important complementary products to cars. Infrastructure, such as roads and bridges, is also a complementary product to cars.

Jun 10, 2024 · The law of demand applies to cars, just as it does to other goods and services. But as we move along the demand curve in response to a change in the price of cars, the substitution possibilities are complex. Understanding these substitution possibilities is critical when firms are choosing the prices to set for the cars that they produce.
Sep 14, 2023 · RMI’s research shows that by 2030, the gas fleet is likely to be falling at a rate of 40 to 70 million per year, or 3-7%. And, the researchers say, since gas cars account for around 25% of ...

Equilibrium
Because the graphs for demand and supply curves both have price on the vertical axis and quantity on the horizontal axis, the demand curve and supply curve for a particular good or service can appear on the same graph. Together, demand and supply determine the price and the quantity that will be bought and sold in a market. Remember this: When two lines on a diagram cross, this intersection usually means something. The point where the supply curve (S) and the demand curve (D) cross in the fig...
Market Failures
Imagine, for example, that the price of a gallon of gasoline was above the equilibrium price—that is, instead of $2.50 per gallon, the price is $3.00 per gallon. The horizontal line at the price of $3.00 in the figure below illustrates this above equilibrium price. At this higher price, the quantity demanded drops from 200 to 130. This decline in quantity reflects how consumers react to the higher price by finding ways to use less gasoline. Moreover, at this higher price of $3.00, the quantit...
Algebraic Equilibrium
Instead of using schedules or graphs to examine the supply and demand within a market, we can also express both as equations. This allows us to compact all of the information into a single mathematical expression. For instance, consider the demand equation below: QD=30−5P.QD=30−5P. We can plug any price in and get the quantity demanded. For example, when the price is set at $3, the quantity demanded is QD=30−5(3)=30−15=15.QD=30−5(3)=30−15=15. The same applies to the supply equation as well. A...
Single Shifts
Let’s begin this discussion with a single economic event. It might be an event that affects demand, like a change in income, population, tastes, prices of substitutes or complements, or expectations about future prices. It might be an event that affects supply, like a change in natural conditions, input prices, or technology, or government policies that affect production. How does this economic event affect equilibrium price and quantity? We will analyze this question using a four-step proces...
Double Shifts
In the previous examples, we examined the impact of a single change on the market. We saw that either supply or demand shifted (not both) and the curve only shifted once. But in reality, it is possible for several factors to change at the same time. Let us explore how we can model several changes within one graph.
To this point in the chapter, we have been assuming that markets are free, that is, they operate with no government intervention. In this section, we will explore the outcomes, both anticipated and otherwise, when government does intervene in a market either to prevent the price of some good or service from rising “too high” or to prevent the price...
A Demand Curve for Gasoline. The demand schedule shows that as price rises, quantity demanded decreases, and vice versa. These points are then graphed, and the line connecting them is the demand curve (D). The downward slope of the demand curve again illustrates the law of demand—the inverse relationship between prices and quantity demanded.

Jan 20, 2022 · Aggregate or Market Demand Curve . The market demand curve describes the quantity demanded by the entire market for a category of goods or services, such as gasoline prices. When the price of oil goes up, all gas stations must raise their prices to cover their costs. Oil prices comprise 70% of gas prices; even if the price drops 50%, drivers ...
