Price Ceiling
Unlock Audio Lesson
Good morning, class! Today we'll discuss price ceilings. Who can tell me what a price ceiling is?
Isn't it the maximum price set by the government for a good?
Exactly! Price ceilings aim to make essential goods affordable. Can anyone give me an example of a product that might have a price ceiling?
Wheat or rice are often examples!
Well done! When a price ceiling is set below the equilibrium price, what tends to happen in the market?
There would be excess demand because more people want to buy it at that lower price.
Correct! This creates a shortage. If there’s a lot of demand and not enough supply, how might consumers respond?
They might start queuing up to get the product!
Exactly! This can lead to long lines and even a black market. Remember, price ceilings are meant to help, but they can cause these unintended issues. Now, let's summarize: Price ceilings make goods affordable but can lead to shortages and black markets.
Price Floor
Unlock Audio Lesson
Now, let’s shift gears to price floors. Can anyone tell me what a price floor is?
It’s the minimum price set by the government for a good.
Right! It's often above the market equilibrium price. What could be a reason for setting a price floor?
To ensure that producers get a fair income, especially in agriculture.
Excellent! So what happens when a price floor is implemented?
There’s excess supply because producers make more at the higher price than consumers are willing to buy.
Exactly! So how might the government respond to this excess supply?
They might buy up the surplus?
Yes! To keep prices stable and support farmers. Remember, price floors protect producer income but can lead to surpluses.
Contrasting Price Controls
Unlock Audio Lesson
Today, we'll compare price ceilings and price floors. What’s a big difference between the two?
A price ceiling is the highest price while a price floor is the lowest price!
Exactly! Both can lead to issues, though. What’s often the outcome of a price ceiling?
It creates shortages because demand exceeds supply.
Yes! And what about a price floor?
That creates surpluses since supply can outpace demand.
Exactly right! Both price controls can lead to unintended consequences. Remember the key points: Ceilings protect consumers but can create shortages; floors ensure producer income but can result in surpluses.
Introduction & Overview

Quick Overview
Standard
In this section, the concepts of price ceilings and price floors are explored within the context of government intervention in markets. Price ceilings, applied to necessary goods to ensure affordability, often result in excess demand, while price floors, set to stabilize prices of certain goods, can create excess supply.

Applications of Supply-Demand Analysis
In Section 5.2, we focus on practical applications of supply-demand analysis, specifically government interventions in markets through price controls — namely, price ceilings and price floors.
- Price Ceiling: This is a legally imposed maximum price for goods often set below the market equilibrium price to make essentials more affordable. For instance, in the wheat market, a price ceiling below the equilibrium leads to consumers demanding more than producers are willing or able to supply, causing a shortage of wheat. Consequently, rationing may be introduced as a way to distribute the limited supply effectively. Price ceilings may lead to long queues for consumers and the emergence of black markets due to unmet demand.
- Price Floor: Conversely, a price floor is a minimum price set above the equilibrium price to protect producers' income, commonly observed in agricultural markets or minimum wage laws. If a price floor is established, it can lead to excess supply as producers, encouraged by the higher price, supply more than what consumers are willing to buy at that price. In such cases, the government might need to buy the surplus to maintain market equilibrium.
Understanding the impact of these controls assists in evaluating market effects and guiding effective economic policies.

In this section, we try to understand how the supply-demand analysis can be applied. In particular, we look at two examples of government intervention in the form of price control. Often, it becomes necessary for the government to regulate the prices of certain goods and services when their prices are either too high or too low in comparison to the desired levels. We will analyse these issues within the framework of perfect competition to look at what impact these regulations have on the market for these goods.
Detailed Explanation
In this introduction, we explore the concept of government intervention in the economy, specifically through price controls. Price controls can take the form of price ceilings (maximum prices) or price floors (minimum prices). Governments implement these controls to correct market failures where they believe prices are not reflecting a fair market value, often leading to affordability issues for essential goods. This section will cover how these interventions can alter supply and demand dynamics.
Examples & Analogies
Think of a scenario where the government wants to ensure that everyone can afford basic food items like bread or milk. If prices rise too high, not everyone may be able to buy these essential items, prompting the government to create a price ceiling so that these goods remain affordable. This helps maintain access for all consumers, particularly those with lower incomes.
Price Ceiling Explanation

It is not very uncommon to come across instances where government fixes a maximum allowable price for certain goods. The government-imposed upper limit on the price of a good or service is called price ceiling. Price ceiling is generally imposed on necessary items like wheat, rice, kerosene, sugar and it is fixed below the market-determined price since at the market-determined price some section of the population will not be able to afford these goods.
Detailed Explanation
Price ceilings are regulations set by the government to limit how high prices can go for certain essential goods. The idea is that by setting a maximum price below the equilibrium market price, it makes these goods more affordable for consumers. However, the downside is that by making these prices lower, it can lead to a shortage of these goods in the market, as suppliers may not find it profitable to sell them at the lower price.
Examples & Analogies
Imagine a situation where there's a sudden increase in demand for rice during a festival. If the price naturally rises due to increased demand, a government might step in to set a price ceiling so that everyone can still buy rice. However, if the price ceiling is set too low, farmers may choose to sell less rice, leading to empty shelves in stores and long lines at ration shops.
Effects of Price Ceiling - Wheat Market

Let us examine the effects of price ceiling on market equilibrium through the example of market for wheat. Figure 5.7 shows the market supply curve SS and the market demand curve DD for wheat. The equilibrium price and quantity of wheat are p and q respectively. When the government imposes price ceiling at p_c which is lower than the equilibrium price level, there will be an excess demand for wheat in the market at that price. The consumers demand q_c kilograms of wheat whereas the firms supply q' kilograms.
Detailed Explanation
When a price ceiling is set below the market equilibrium price, it disrupts the balance between supply and demand. In the wheat market example, if the price ceiling is set at p_c, demand rises because the price is cheaper, but supply drops because producers can’t cover their costs at such a low price. This imbalance creates excess demand, meaning consumers want to buy more wheat than what is available in the market.
Examples & Analogies
Consider how popular concert tickets are priced. If a government set a price ceiling to ensure 'everyone can enjoy the event', ticket buyers would flock to buy tickets at that cheap price. However, sellers may choose to offer fewer tickets because the profit isn't enough, resulting in frustrated fans being unable to buy tickets despite their willingness to pay more.
Distribution Issues with Price Ceiling

Hence, though the intention of the government was to help the consumers, it could end up creating shortage of wheat. How is the quantity of wheat (q') then distributed among the consumers? One way of doing this is to distribute it to everyone, through a system of rationing. Ration coupons are issued to the consumers so that no individual can buy more than a certain amount of wheat and this stipulated amount of wheat is sold through ration shops which are also called fair price shops.
Detailed Explanation
When a price ceiling leads to a shortage, the government must implement measures to allocate the limited supply of goods fairly among consumers. Rationing is one way to achieve this, where individuals receive ration coupons that allow them to purchase a set quantity of the good. This helps ensure that more people can access the goods, even if they cannot get enough to meet their full needs.
Examples & Analogies
Think of how during a natural disaster, authorities might need to ration supplies like water and food. Everyone might receive a limited amount based on their needs assessed via a coupon system, ensuring that while there isn’t enough for everyone’s normal use, everyone can at least get some basic supplies to survive.
Price Floor Explanation
Unlock Audio Book
Signup and Enroll to the course for listening the Audio Book
For certain goods and services, fall in price below a particular level is not desirable and hence the government sets floors or minimum prices for these goods and services. The government-imposed lower limit on the price that may be charged for a particular good or service is called price floor. Most well-known examples of imposition of price floor are agricultural price support programmes and the minimum wage legislation.
Detailed Explanation
Price floors are established to prevent prices from falling too low, typically to protect producers or workers. It ensures that suppliers receive a minimum price for their goods or that workers earn a minimum wage that allows them to meet basic living expenses. A common example includes agricultural products where farmers must receive enough income to sustain their operations.
Examples & Analogies
Envision a situation where farmers are struggling to make a profit because the market price of crops has dropped significantly. To help them, the government implements a minimum price for their crops, ensuring that they don’t sell for too little and can continue to operate their farms sustainably.
Effects of Price Floor on Market

Figure 5.8 shows the market supply and the market demand curve for a commodity on which price floor is imposed. The market equilibrium here would occur at price p and quantity q. But when the government imposes a floor higher than the equilibrium price at p_f, the market demand is q_f whereas the firms want to supply q′, thereby leading to an excess supply in the market equal to q_f q′.
Detailed Explanation
With a price floor set above the equilibrium price, it creates excess supply in the market. This means that the quantity supplied by producers exceeds the quantity demanded by consumers at that price. As a result, unsold goods accumulate, leading to waste or requiring government intervention, such as purchasing the surplus to stabilize market prices.
Examples & Analogies
Imagine a minimum wage law that sets wages at a level where employers don’t want to hire as many workers because their costs have risen. Consequently, more people might apply for jobs than there are available positions, just like a bouquet seller has more flowers than customers willing to buy them at the set price, creating an excess supply situation.
