When the price of a substitute increases, the demand curve for the original good will shift to the left. This happens because the increase in the price of the substitute makes it less attractive to consumers and causes them to switch back to the original good.
As the demand for the original good increases, the demand curve will shift to the left, resulting in a lower equilibrium price and a higher equilibrium quantity of the original good. This can be seen in the graph below.
As the price of the substitute increases from P2 to P3, the demand for the original good increases from Q2 to Q3. This causes the demand curve to shift from D2 to D3, resulting in a lower equilibrium price and a higher equilibrium quantity.

Does the price of a substitute good shift the demand curve?
Yes, the price of a substitute good can shift the demand for a good. When the price of a substitute good increases, demand for the original good decreases and vice versa. This means that, inversely, when the price of a substitute good decreases, the demand for the original good increases.
This occurs because when the price of a substitute good increases, consumers may substitute the original good for the substitute good which drives demand for the original good down. Conversely, when the price of a substitute good decreases, consumers may substitute the substitute good for the original good which will drive demand for the original good up.
Therefore, the price of a substitute good can definitely have an effect on the demand for a good.
Does demand decrease in the price of substitutes?
Yes, demand generally decreases when the price of substitutes falls. This is due to the fact that when the price of the substitute falls, it becomes more attractive to the consumer. For example, if the price of a certain type of soda decreases, it becomes more desirable than other brands of soda and people may choose to buy that particular brand instead of the other brand.
As a result, the demand for the other brands of soda may decrease. Likewise, when the price of a substitute product decreases, people may be more likely to purchase that product instead of the original one, thus causing demand for the original product to decrease.
What shifts the demand curve?
Demand curves shift when there is a change in factors influencing the quantity of a good or service that buyers are willing and able to buy. These factors can include changes in price (or the expectation of future changes in price), changes in income, changes in the prices of related goods, changes in tastes or preferences of buyers, and changes in the number of buyers.
When any of these changes, the demand curve will shift to the right or left, depending on the direction of the change. For instance, a decrease in price will generally cause the demand curve to shift to the right, reflecting the increasing quantity that buyers are willing to purchase at the price.
Similarly, an increase in income will generally cause the demand curve to shift to the right, reflecting increased demand for the good or service.
What shifts the supply curve leftwards?
The supply curve shows the relationship between the quantity of goods that suppliers are willing and able to offer at a particular price. When the supply curve shifts leftwards, it means there is a decrease in the quantity of goods supplied at each price.
This can occur due to various internal and external factors.
Internally, the decrease in the quantity supplied could occur due to a decrease in the production technology and capacity of producers, the presence of less efficient producers in the market, a decrease in the price of production inputs, increased production costs, or even a decrease in the number of suppliers.
Externally, a decrease in the quantity supplied could occur due to external economic shocks such as changes in regulations or economic policies, changes in consumer preferences or tastes and the introduction of substitute goods or services in the market.
Other factors such as natural disasters or a fall in the global demand for goods and services can also cause the supply curve to shift leftwards.
Why does a price increase cause a substitution effect?
When the price of a good increases, the substitution effect is created in that individuals will substitute the item in question for a similar or identical good that is less expensive. In other words, when the price of a product increases, the demand for that product from consumers will most likely decrease.
As a result, the demand for less expensive alternatives to that product will increase as those alternatives become relatively more attractive to consumers. This shift in demand for cheaper alternatives is the substitution effect and it can be seen across a wide range of markets and products.
Furthermore, the substitution effect will often lead to decreased market share for the more expensive good, as cheaper options become more attractive alternatives. In some cases, manufacturers also respond to the substitution effect by lowering the prices of their goods in order to remain competitive in the market.
This is a form of competition and it will often result in a return in demand for the original good, as the substitute goods become relatively less attractive. This can be described as a ‘price-elasticity of demand’, in that the price elasticity of demand will often change when the price of a good increases.
Overall, the substitution effect is a natural economic response to price increases and it is necessary for the economics of the market to remain in balance. The substitution effect helps to maintain competition, keep prices fair, and keep customers from over-paying for goods.
What causes the substitution effect?
The substitution effect occurs when an increase in the price of a good or service causes consumers to substitute an inferior or cheaper version of the good or service, in order to save money. This effect is more prevalent in goods and services that are easily substitutable, such as some food items and forms of transportation.
The substitution effect is driven by two major factors. Firstly, it is driven by the principle of diminishing marginal utility, meaning that people are less likely to purchase something that has become more expensive.
Secondly, it is driven by the law of demand, which suggests that as the price of a good or service increases, demand for it decreases.
The substitution effect can be seen in a variety of markets. For example, when the price of beef increases, many consumers may decide to purchase cheaper cuts of meat or switch to seafood or poultry instead.
Similarly, when the price of gasoline rises, people may opt to use more public transportation or carpool to decrease the amount that they spend on fuel each month.
Overall, the substitution effect occurs when an increase in the price of a good or service causes people to switch to a cheaper or inferior version in order to save money. This effect can be seen in a wide range of markets and is driven by the principle of diminishing marginal utility and the law of demand.
Is the substitution effect positive or negative?
The substitution effect is positive when the price of a good or service increases; in other words, this states that an individual will substitute an item of lesser value for a more expensive item. For example, if the price of beef increases, you may choose to substitute with a cheaper animal-based protein such as chicken.
This shift from beef to chicken then produces a positive substitution effect.
The substitution effect can also be negative. For example, the rise in the price of gasoline may lead a consumer to substitute walking or bicycling instead of driving. Although this would be a healthier choice, the substitution of activities due to the price of gasoline produces a negative substitution effect.
Overall, the substitution effect is affected by a change in price as well as the substitution of goods or services. If a good or service becomes more expensive, then the substitution effect is typically positive.
On the other hand, if something becomes cheaper then the substitution effect may be negative.
Will the demand curve will shift to the left if the price of substitute products increases?
Yes, the demand curve will shift to the left if the price of substitute products increases. When the price of substitute products increases, it makes them relatively more expensive than the product in question, making customers less likely to purchase substitute products and more likely to purchase the product in question.
This results in a decrease in demand for the product in question, shifting the demand curve to the left. In addition, when the price of substitute products increases, customers may also become more inclined to purchase the product in question (versus its substitutes), further shifting the demand curve to the left.
What causes a demand curve to shift to the left?
A demand curve can shift to the left due to a variety of factors, such as a decrease in the price of a substitute product or service, a decrease in the income of potential customers, or an increase in the price of the original good or service.
Additionally, a change in the tastes or preferences of potential customers, an increase in the number of available substitutes, or an increase in the price of goods or services that are complementary to the original product can also cause a demand curve to shift to the left.
Other external factors can also cause a demand curve to shift to the left, such as a change in the attitude of potential customers toward the original product or service due to a change in the perception of product quality, an increase in the amount of taxes imposed on the product, or a change in the population size of potential customers.
In the case of population size, if the population of potential customers decreases, the demand for the original product or service can decrease, thus causing the demand curve to shift to the left.
In conclusion, a demand curve can shift to the left due to change in price and income levels, consumer preferences, the availability of substitutes and complements, or external factors, such as changes in taxes, population size, or the perceived quality of the product or service.
What effect do substitutes have on demand?
Substitutes have a significant effect on demand, as they increase consumer choice by providing different options and can drive down prices by creating competition. When a substitute good is available, consumers are more willing to switch between the two goods, which increases the responsiveness of demand to price changes.
If a consumer believes that they could get a cheaper or higher quality version of a good, they will be less willing to pay a higher price. This can lead to a shift in market share or demand away from the original good and towards the substitute.
The availability of substitute goods can also reduce barriers to entry for new firms in a given market. By allowing for competition, substitutes increase the pressure on existing firms to remain competitive, and can reduce their market power.
This can result in lower prices for consumers and more competitive markets in the long run.
Finally, the presence of substitutes can also increase consumer satisfaction. By providing with different options, consumers are able to comparison shop to find the best deal for their needs, and are more likely to find a good that meets their needs and budget.
This can result in increased satisfaction and loyalty, which can then drive demand for the substitutes in the long run.
What is the impact of a price change into substitution and income effects?
A price change can have an impact on the substitution and income effects with regards to consumer buying behavior. On the substitution effect side, when the price of one good increases, a consumer may be motivated to substitute the good with one that is cheaper.
For example, if the price of beef rises, consumers may opt to buy chicken instead, if chicken is seen as a suitable substitute.
On the income effect side, when a price increases, a consumer’s purchasing power is reduced, if their income remains unchanged. This leads to a reduction in the demand for a good as the price increases, because they have less to spend.
Furthermore, if the good is considered an inferior good, the demand would decrease even further as the price of the good increases. For instance, if the price of a generic brand of soda rises, the demand for them may decrease as consumers move on to buy more expensive brands of soda.
In summary, a price change can cause changes in both the substitution and income effect, which affects the demand for a good.
