Demand and Supply

Shifts in Demand and Supply for Goods and Services

Learning Objectives

By the stop of this section, you will be able to:

• Identify factors that affect need
• Graph demand curves and demand shifts
• Identify factors that impact supply
• Graph supply curves and supply shifts

The previous module explored how price affects the quantity demanded and the quantity supplied. The consequence was the demand curve and the supply curve. Price, however, is not the only factor that influences demand, nor is it the only thing that influences supply. For instance, how is demand for vegetarian nutrient afflicted if, say, health concerns cause more consumers to avert eating meat? How is the supply of diamonds afflicted if diamond producers discover several new diamond mines? What are the major factors, in improver to the toll, that influence demand or supply?

Visit this website to read a cursory notation on how marketing strategies tin can influence supply and demand of products.

What Factors Affect Need?

We divers demand as the amount of some product a consumer is willing and able to purchase at each toll. That suggests at to the lowest degree 2 factors in improver to price that affect need. Willingness to purchase suggests a desire, based on what economists call tastes and preferences. If you neither need nor desire something, you will not buy it. Power to purchase suggests that income is important. Professors are usually able to afford meliorate housing and transportation than students, because they take more than income. Prices of related goods can impact demand as well. If you need a new car, the price of a Honda may bear upon your demand for a Ford. Finally, the size or composition of the population tin touch on demand. The more children a family unit has, the greater their demand for habiliment. The more driving-historic period children a family has, the greater their need for machine insurance, and the less for diapers and baby formula.

These factors matter for both individual and market demand equally a whole. Exactly how do these various factors impact demand, and how do we show the furnishings graphically? To answer those questions, nosotros need the ceteris paribus assumption.

The Ceteris Paribus Assumption

A demand curve or a supply curve is a relationship between two, and only ii, variables: quantity on the horizontal axis and price on the vertical axis. The assumption backside a demand curve or a supply curve is that no relevant economic factors, other than the product'south price, are changing. Economists call this assumption ceteris paribus, a Latin phrase meaning "other things being equal." Any given demand or supply bend is based on the ceteris paribus assumption that all else is held equal. A demand curve or a supply curve is a relationship betwixt two, and simply 2, variables when all other variables are kept constant. If all else is not held equal, then the laws of supply and need will not necessarily concur, as the following Clear It Up characteristic shows.

When does ceteris paribus utilize?

We typically apply ceteris paribus when we notice how changes in price affect need or supply, but we can utilise ceteris paribus more generally. In the existent world, demand and supply depend on more factors than just price. For example, a consumer'due south demand depends on income and a producer's supply depends on the cost of producing the production. How tin we analyze the issue on demand or supply if multiple factors are changing at the same time—say toll rises and income falls? The answer is that we examine the changes one at a fourth dimension, assuming the other factors are held constant.

For example, we can say that an increase in the price reduces the amount consumers volition purchase (assuming income, and annihilation else that affects demand, is unchanged). Additionally, a decrease in income reduces the amount consumers can afford to purchase (assuming price, and annihilation else that affects demand, is unchanged). This is what the ceteris paribus assumption really means. In this detail instance, after we clarify each factor separately, we can combine the results. The corporeality consumers buy falls for two reasons: beginning because of the college price and 2d because of the lower income.

How Does Income Bear on Demand?

Let'south apply income as an instance of how factors other than price bear upon demand. (Effigy) shows the initial demand for automobiles equally D₀. At point Q, for case, if the price is $twenty,000 per machine, the quantity of cars demanded is 18 million. D₀ as well shows how the quantity of cars demanded would change as a consequence of a college or lower cost. For example, if the price of a auto rose to $22,000, the quantity demanded would decrease to 17 meg, at point R.

The original demand curve D₀, like every demand bend, is based on the ceteris paribus assumption that no other economically relevant factors modify. Now imagine that the economy expands in a way that raises the incomes of many people, making cars more than affordable. How will this affect demand? How tin can we evidence this graphically?

Return to (Figure). The price of cars is still $20,000, but with college incomes, the quantity demanded has now increased to twenty million cars, shown at point South. As a consequence of the higher income levels, the need curve shifts to the correct to the new demand bend D₁, indicating an increase in need. (Figure) shows clearly that this increased need would occur at every toll, non only the original 1.

Shifts in Demand: A Car Example

Increased need ways that at every given price, the quantity demanded is higher, so that the demand curve shifts to the right from D₀ to D_one. Decreased need means that at every given price, the quantity demanded is lower, and then that the demand curve shifts to the left from D₀ to D_two.

Price and Demand Shifts: A Car Case

Toll	Decrease to D2	Original Quantity Demanded D0	Increment to D1
$16,000	17.half dozen meg	22.0 1000000	24.0 million
$18,000	16.0 million	20.0 million	22.0 million
$20,000	14.4 million	18.0 million	20.0 million
$22,000	13.6 1000000	17.0 meg	nineteen.0 one thousand thousand
$24,000	thirteen.2 one thousand thousand	xvi.v one thousand thousand	18.5 million
$26,000	12.eight 1000000	xvi.0 million	18.0 one thousand thousand

Now, imagine that the economy slows down so that many people lose their jobs or piece of work fewer hours, reducing their incomes. In this case, the decrease in income would pb to a lower quantity of cars demanded at every given cost, and the original demand curve D₀ would shift left to D_two. The shift from D₀ to D₂ represents such a decrease in demand: At any given price level, the quantity demanded is at present lower. In this case, a price of $20,000 means 18 million cars sold along the original demand curve, but but 14.4 meg sold subsequently need fell.

When a demand bend shifts, it does not hateful that the quantity demanded past every individual buyer changes by the same amount. In this instance, not everyone would accept college or lower income and not everyone would buy or not buy an additional car. Instead, a shift in a demand curve captures a pattern for the market every bit a whole.

In the previous department, we argued that higher income causes greater demand at every price. This is true for most goods and services. For some—luxury cars, vacations in Europe, and fine jewelry—the result of a rise in income can exist especially pronounced. A production whose demand rises when income rises, and vice versa, is chosen a normal good. A few exceptions to this pattern practice exist. Every bit incomes rising, many people volition purchase fewer generic brand groceries and more proper name brand groceries. They are less likely to buy used cars and more likely to buy new cars. They will exist less likely to rent an apartment and more likely to own a home. A product whose need falls when income rises, and vice versa, is called an inferior good. In other words, when income increases, the demand curve shifts to the left.

Other Factors That Shift Demand Curves

Income is not the only cistron that causes a shift in demand. Other factors that modify demand include tastes and preferences, the composition or size of the population, the prices of related appurtenances, and even expectations. A alter in any one of the underlying factors that determine what quantity people are willing to buy at a given price will crusade a shift in demand. Graphically, the new need curve lies either to the right (an increase) or to the left (a decrease) of the original demand curve. Let's look at these factors.

Changing Tastes or Preferences

From 1980 to 2014, the per-person consumption of chicken by Americans rose from 48 pounds per yr to 85 pounds per yr, and consumption of beef barbarous from 77 pounds per year to 54 pounds per year, co-ordinate to the U.S. Section of Agriculture (USDA). Changes like these are largely due to movements in sense of taste, which change the quantity of a good demanded at every price: that is, they shift the demand bend for that skilful, rightward for chicken and leftward for beef.

Changes in the Composition of the Population

The proportion of elderly citizens in the The states population is rising. Information technology rose from ix.8% in 1970 to 12.vi% in 2000, and volition be a projected (by the U.S. Census Bureau) 20% of the population past 2030. A society with relatively more children, similar the U.s. in the 1960s, will have greater need for goods and services like tricycles and twenty-four hours care facilities. A social club with relatively more elderly persons, as the The states is projected to have past 2030, has a higher need for nursing homes and hearing aids. Similarly, changes in the size of the population can touch the need for housing and many other goods. Each of these changes in demand volition be shown every bit a shift in the need bend.

Changes in the prices of related appurtenances such as substitutes or complements also can affect the demand for a product. A substitute is a good or service that we can employ in place of another good or service. As electronic books, like this one, become more available, yous would wait to see a decrease in need for traditional printed books. A lower cost for a substitute decreases need for the other production. For example, in recent years equally the price of tablet computers has fallen, the quantity demanded has increased (considering of the police force of demand). Since people are purchasing tablets, there has been a decrease in demand for laptops, which we can show graphically every bit a leftward shift in the need bend for laptops. A higher price for a substitute proficient has the contrary upshot.

Other appurtenances are complements for each other, significant we often use the goods together, considering consumption of 1 good tends to heighten consumption of the other. Examples include breakfast cereal and milk; notebooks and pens or pencils, golf game balls and golf clubs; gasoline and sport utility vehicles; and the five-mode combination of bacon, lettuce, love apple, mayonnaise, and breadstuff. If the price of golf clubs rises, since the quantity demanded of golf game clubs falls (because of the law of demand), need for a complement good like golf assurance decreases, too. Similarly, a higher price for skis would shift the demand curve for a complement expert like ski resort trips to the left, while a lower price for a complement has the reverse event.

Changes in Expectations about Future Prices or Other Factors that Touch Demand

While it is clear that the price of a good affects the quantity demanded, it is also true that expectations virtually the future price (or expectations about tastes and preferences, income, and then on) can affect demand. For example, if people hear that a hurricane is coming, they may rush to the store to buy flashlight batteries and bottled water. If people acquire that the price of a good like coffee is likely to rise in the future, they may caput for the shop to stock up on coffee at present. Nosotros bear witness these changes in need as shifts in the bend. Therefore, a shift in demand happens when a modify in some economic factor (other than price) causes a different quantity to be demanded at every toll. The following Work It Out feature shows how this happens.

Shift in Demand

A shift in demand ways that at whatsoever price (and at every toll), the quantity demanded will be different than it was before. Following is an example of a shift in demand due to an income increase.

Step one. Draw the graph of a demand bend for a normal good similar pizza. Selection a price (like P₀). Identify the corresponding Q₀. See an case in (Figure).

Need Curve

Nosotros can use the need curve to identify how much consumers would buy at whatsoever given toll.

Footstep 2. Suppose income increases. Every bit a result of the change, are consumers going to buy more or less pizza? The answer is more. Depict a dotted horizontal line from the called price, through the original quantity demanded, to the new indicate with the new Q₁. Depict a dotted vertical line downwardly to the horizontal axis and characterization the new Q₁. (Effigy) provides an instance.

Demand Curve with Income Increase

With an increase in income, consumers will buy larger quantities, pushing demand to the right.

Pace 3. Now, shift the curve through the new point. You volition encounter that an increase in income causes an up (or rightward) shift in the demand curve, then that at any price the quantities demanded will be higher, as (Figure) illustrates.

Need Bend Shifted Right

With an increment in income, consumers will purchase larger quantities, pushing need to the correct, and causing the need curve to shift correct.

Summing Upwards Factors That Modify Demand

(Figure) summarizes six factors that can shift demand curves. The management of the arrows indicates whether the demand curve shifts represent an increase in demand or a decrease in demand. Detect that a modify in the price of the practiced or service itself is not listed among the factors that tin can shift a demand bend. A change in the cost of a good or service causes a movement along a specific demand bend, and it typically leads to some change in the quantity demanded, merely it does not shift the demand curve.

Factors That Shift Demand Curves

(a) A list of factors that can cause an increase in need from D₀ to D₁. (b) The same factors, if their direction is reversed, tin cause a decrease in need from D₀ to D₁.

When a demand bend shifts, it will then intersect with a given supply curve at a dissimilar equilibrium price and quantity. Nosotros are, yet, getting ahead of our story. Before discussing how changes in demand can affect equilibrium price and quantity, we first demand to hash out shifts in supply curves.

How Production Costs Bear on Supply

A supply bend shows how quantity supplied will change every bit the price rises and falls, assuming ceteris paribus so that no other economically relevant factors are changing. If other factors relevant to supply exercise modify, then the unabridged supply curve volition shift. Just as we described a shift in demand every bit a modify in the quantity demanded at every price, a shift in supply means a change in the quantity supplied at every price.

In thinking about the factors that affect supply, think what motivates firms: profits, which are the difference between revenues and costs. A firm produces goods and services using combinations of labor, materials, and machinery, or what nosotros call inputs or factors of production. If a firm faces lower costs of production, while the prices for the adept or service the firm produces remain unchanged, a firm's profits become up. When a firm's profits increment, it is more motivated to produce output, since the more than it produces the more profit it will earn. When costs of production autumn, a firm will tend to supply a larger quantity at any given price for its output. Nosotros tin can show this by the supply curve shifting to the right.

Take, for example, a messenger company that delivers packages around a city. The company may find that ownership gasoline is i of its chief costs. If the price of gasoline falls, then the visitor will find it tin deliver messages more cheaply than before. Since lower costs correspond to higher profits, the messenger company may now supply more of its services at whatever given price. For example, given the lower gasoline prices, the company tin now serve a greater expanse, and increase its supply.

Conversely, if a business firm faces college costs of production, so it volition earn lower profits at whatsoever given selling price for its products. As a result, a higher cost of production typically causes a house to supply a smaller quantity at whatsoever given price. In this example, the supply curve shifts to the left.

Consider the supply for cars, shown by curve S₀ in (Figure). Point J indicates that if the price is $20,000, the quantity supplied volition be 18 million cars. If the price rises to $22,000 per car, ceteris paribus, the quantity supplied volition ascent to 20 million cars, equally point K on the S₀ curve shows. Nosotros can show the same information in tabular array grade, as in (Figure).

Shifts in Supply: A Automobile Example

Decreased supply means that at every given price, the quantity supplied is lower, so that the supply curve shifts to the left, from S₀ to S₁. Increased supply means that at every given toll, the quantity supplied is higher, so that the supply curve shifts to the right, from South₀ to S₂.

Price and Shifts in Supply: A Car Example

Price	Decrease to Si	Original Quantity Supplied S0	Increase to Southward2
$16,000	10.5 one thousand thousand	12.0 million	xiii.2 million
$eighteen,000	13.5 one thousand thousand	xv.0 million	16.5 million
$20,000	xvi.5 million	18.0 meg	nineteen.eight one thousand thousand
$22,000	18.5 million	20.0 million	22.0 million
$24,000	xix.five million	21.0 million	23.ane million
$26,000	twenty.five meg	22.0 million	24.two million

Now, imagine that the price of steel, an important ingredient in manufacturing cars, rises, so that producing a machine has become more expensive. At any given price for selling cars, car manufacturers volition react by supplying a lower quantity. We can bear witness this graphically as a leftward shift of supply, from S₀ to S₁, which indicates that at any given price, the quantity supplied decreases. In this example, at a toll of $20,000, the quantity supplied decreases from 18 1000000 on the original supply bend (Due south₀) to xvi.five million on the supply curve South_i, which is labeled as point L.

Conversely, if the cost of steel decreases, producing a car becomes less expensive. At any given cost for selling cars, car manufacturers can now await to earn higher profits, so they will supply a higher quantity. The shift of supply to the right, from S₀ to Due south₂, means that at all prices, the quantity supplied has increased. In this example, at a price of $twenty,000, the quantity supplied increases from 18 million on the original supply bend (Southward₀) to 19.8 meg on the supply curve S_ii, which is labeled M.

Other Factors That Affect Supply

In the example above, nosotros saw that changes in the prices of inputs in the production process will touch on the price of production and thus the supply. Several other things affect the toll of production, too, such equally changes in conditions or other natural conditions, new technologies for production, and some government policies.

Changes in conditions and climate will impact the price of production for many agricultural products. For example, in 2014 the Manchurian Plain in Northeastern People's republic of china, which produces almost of the state'due south wheat, corn, and soybeans, experienced its most astringent drought in fifty years. A drought decreases the supply of agricultural products, which means that at any given price, a lower quantity will be supplied. Conversely, especially good weather would shift the supply curve to the right.

When a business firm discovers a new technology that allows the firm to produce at a lower cost, the supply curve will shift to the right, besides. For instance, in the 1960s a major scientific effort nicknamed the Green Revolution focused on breeding improved seeds for basic crops like wheat and rice. By the early on 1990s, more 2-thirds of the wheat and rice in depression-income countries effectually the world used these Green Revolution seeds—and the harvest was twice as high per acre. A technological comeback that reduces costs of production volition shift supply to the correct, so that a greater quantity will be produced at whatever given price.

Government policies can affect the cost of product and the supply curve through taxes, regulations, and subsidies. For instance, the U.S. government imposes a tax on alcoholic beverages that collects about $8 billion per yr from producers. Businesses treat taxes as costs. College costs decrease supply for the reasons we discussed above. Other examples of policy that can bear on price are the broad array of government regulations that require firms to spend money to provide a cleaner surround or a safer workplace. Complying with regulations increases costs.

A government subsidy, on the other hand, is the reverse of a tax. A subsidy occurs when the government pays a firm straight or reduces the firm'south taxes if the house carries out certain actions. From the firm's perspective, taxes or regulations are an additional cost of production that shifts supply to the left, leading the firm to produce a lower quantity at every given cost. Government subsidies reduce the cost of production and increase supply at every given price, shifting supply to the right. The following Work It Out feature shows how this shift happens.

Shift in Supply

Nosotros know that a supply curve shows the minimum price a firm will take to produce a given quantity of output. What happens to the supply curve when the price of production goes up? Following is an example of a shift in supply due to a production price increment.

Stride ane. Depict a graph of a supply curve for pizza. Pick a quantity (like Q₀). If you draw a vertical line up from Q₀ to the supply curve, yous will meet the cost the business firm chooses. (Effigy) provides an case.

Supply Curve

You lot can utilize a supply curve to prove the minimum price a firm volition accept to produce a given quantity of output.

Step 2. Why did the house choose that cost and not some other? I way to think virtually this is that the price is equanimous of two parts. The start part is the cost of producing pizzas at the margin; in this instance, the cost of producing the pizza, including cost of ingredients (due east.chiliad., dough, sauce, cheese, and pepperoni), the price of the pizza oven, the shop rent, and the workers' wages. The 2nd part is the house's desired profit, which is determined, among other factors, by the profit margins in that particular business concern. If you add these ii parts together, yous become the price the firm wishes to charge. The quantity Q0 and associated price P0 requite you ane signal on the firm's supply curve, every bit (Figure) illustrates.

Setting Prices

The price of production and the desired profit equal the toll a firm will prepare for a product.

Step iii. Now, suppose that the cost of production increases. Mayhap cheese has become more expensive by $0.75 per pizza. If that is true, the firm volition desire to heighten its price by the corporeality of the increase in cost ($0.75). Depict this bespeak on the supply curve direct to a higher place the initial point on the curve, but $0.75 college, as (Effigy) shows.

Increasing Costs Leads to Increasing Toll

Because the cost of production and the desired profit equal the price a firm will ready for a product, if the toll of production increases, the cost for the production will likewise need to increase.

Stride 4. Shift the supply curve through this betoken. You volition come across that an increase in cost causes an upward (or a leftward) shift of the supply bend and then that at whatsoever price, the quantities supplied will exist smaller, as (Figure) illustrates.

Supply Curve Shifts

When the price of production increases, the supply curve shifts upwardly to a new cost level.

Summing Up Factors That Change Supply

Changes in the cost of inputs, natural disasters, new technologies, and the impact of government decisions all touch the cost of production. In turn, these factors affect how much firms are willing to supply at whatever given price.

(Effigy) summarizes factors that change the supply of appurtenances and services. Find that a change in the price of the production itself is not among the factors that shift the supply curve. Although a change in price of a good or service typically causes a alter in quantity supplied or a movement along the supply bend for that specific expert or service, it does not cause the supply curve itself to shift.

Factors That Shift Supply Curves

(a) A list of factors that can crusade an increase in supply from S₀ to S₁. (b) The aforementioned factors, if their direction is reversed, tin cause a decrease in supply from Due south₀ to S₁.

Because demand and supply curves announced on a two-dimensional diagram with simply price and quantity on the axes, an unwary visitor to the land of economics might be fooled into assertive that economics is nigh only 4 topics: demand, supply, price, and quantity. However, demand and supply are actually "umbrella" concepts: demand covers all the factors that touch demand, and supply covers all the factors that bear upon supply. We include factors other than price that impact demand and supply are included by using shifts in the demand or the supply curve. In this way, the two-dimensional demand and supply model becomes a powerful tool for analyzing a wide range of economic circumstances.

Key Concepts and Summary

Economists often use the ceteris paribus or "other things being equal" assumption: while examining the economic bear upon of ane event, all other factors remain unchanged for assay purposes. Factors that can shift the need curve for goods and services, causing a different quantity to be demanded at any given price, include changes in tastes, population, income, prices of substitute or complement appurtenances, and expectations about future atmospheric condition and prices. Factors that tin can shift the supply curve for goods and services, causing a different quantity to be supplied at whatever given price, include input prices, natural conditions, changes in technology, and government taxes, regulations, or subsidies.

Cocky-Check Questions

Why do economists apply the ceteris paribus assumption?

To make it easier to analyze complex problems. Ceteris paribus allows yous to await at the effect of one factor at a fourth dimension on what it is y'all are trying to analyze. When you have analyzed all the factors individually, you add the results together to get the final answer.

In an analysis of the market for pigment, an economist discovers the facts listed beneath. Country whether each of these changes will affect supply or need, and in what direction.

1. There have recently been some of import toll-saving inventions in the technology for making paint.
2. Paint is lasting longer, and so that holding owners demand non repaint as oft.
3. Because of astringent hailstorms, many people need to repaint at present.
4. The hailstorms damaged several factories that make pigment, forcing them to shut down for several months.

1. An improvement in applied science that reduces the cost of production will crusade an increase in supply. Alternatively, y'all can think of this as a reduction in price necessary for firms to supply any quantity. Either fashion, this can exist shown as a rightward (or downward) shift in the supply curve.
2. An improvement in production quality is treated as an increase in tastes or preferences, pregnant consumers demand more pigment at any price level, so demand increases or shifts to the right. If this seems counterintuitive, annotation that need in the future for the longer-lasting paint volition fall, since consumers are essentially shifting demand from the future to the present.
3. An increase in need causes an increase in demand or a rightward shift in the need curve.
4. Factory damage ways that firms are unable to supply as much in the nowadays. Technically, this is an increase in the toll of production. Either way yous wait at it, the supply curve shifts to the left.

Many changes are affecting the market place for oil. Predict how each of the following events will touch the equilibrium price and quantity in the market place for oil. In each case, state how the effect will affect the supply and demand diagram. Create a sketch of the diagram if necessary.

1. Cars are becoming more than fuel efficient, and therefore get more miles to the gallon.
2. The winter is exceptionally cold.
3. A major discovery of new oil is fabricated off the coast of Norway.
4. The economies of some major oil-using nations, like Nippon, slow down.
5. A war in the Middle East disrupts oil-pumping schedules.
6. Landlords install additional insulation in buildings.
7. The price of solar energy falls dramatically.
8. Chemical companies invent a new, popular kind of plastic made from oil.

1. More fuel-efficient cars means in that location is less demand for gasoline. This causes a leftward shift in the demand for gasoline and thus oil. Since the demand curve is shifting downward the supply curve, the equilibrium price and quantity both fall.
2. Cold weather increases the demand for heating oil. This causes a rightward shift in the demand for heating oil and thus oil. Since the demand curve is shifting up the supply curve, the equilibrium cost and quantity both ascent.
3. A discovery of new oil will make oil more than abundant. This can be shown as a rightward shift in the supply curve, which will cause a decrease in the equilibrium price along with an increase in the equilibrium quantity. (The supply curve shifts downwards the need curve so toll and quantity follow the law of demand. If price goes downward, then the quantity goes up.)
4. When an economy slows downwards, it produces less output and demands less input, including energy, which is used in the production of virtually everything. A decrease in demand for free energy will be reflected as a subtract in the demand for oil, or a leftward shift in demand for oil. Since the demand curve is shifting downwards the supply curve, both the equilibrium price and quantity of oil volition fall.
5. Disruption of oil pumping will reduce the supply of oil. This leftward shift in the supply curve will show a movement up the demand curve, resulting in an increment in the equilibrium toll of oil and a decrease in the equilibrium quantity.
6. Increased insulation will decrease the demand for heating. This leftward shift in the demand for oil causes a motility downwardly the supply bend, resulting in a decrease in the equilibrium toll and quantity of oil.
7. Solar free energy is a substitute for oil-based free energy. Then if solar energy becomes cheaper, the demand for oil will decrease as consumers switch from oil to solar. The decrease in demand for oil will be shown as a leftward shift in the demand bend. As the need curve shifts down the supply curve, both equilibrium price and quantity for oil will fall.
8. A new, popular kind of plastic will increase the demand for oil. The increase in demand will exist shown as a rightward shift in need, raising the equilibrium price and quantity of oil.
