Business activities encompass all actions undertaken by organizations to achieve their goals, primarily focused on producing and distributing goods and services. These activities can be broadly classified into three main categories: Industry, Commerce, and Service. Each category includes specific functions and subcategories that contribute to the business ecosystem.

1. Industry

Industries are concerned with the production and processing of goods and the extraction of natural resources. They form the foundation of business activities. Industries can be further classified into the following types:

(a) Primary Industry

Primary industries involve the extraction and harvesting of natural resources. These are the backbone of an economy, providing raw materials for further production.

• Agriculture: Farming, forestry, and horticulture.
• Fishing: Harvesting fish and other aquatic resources.
• Mining: Extraction of minerals, coal, oil, and natural gas.
• Quarrying: Extraction of stones and other building materials.

(b) Secondary Industry

Secondary industries focus on manufacturing and construction. They process raw materials from primary industries into finished or semi-finished goods.

• Manufacturing: Conversion of raw materials into consumer goods (e.g., textiles, electronics).
• Construction: Building infrastructure, such as roads, bridges, and buildings.

(c) Tertiary Industry

This sector provides support services essential for primary and secondary industries, facilitating the distribution of goods and services. Examples include transport, banking, and retail.

(d) Quaternary and Quinary Industry

These newer classifications include knowledge-based and decision-making industries, such as IT, research, and consulting.

2. Commerce

Commerce involves the activities required to ensure the smooth exchange of goods and services from producers to consumers. It is the connecting link between production and consumption and is classified into:

(a) Trade

Trade refers to the buying and selling of goods and services. It can be categorized as:

• Internal Trade: Conducted within a country, including wholesale (bulk transactions) and retail (direct to consumers).
• External Trade: Transactions across international borders, including import, export, and entrepôt trade (re-exporting goods).

(b) Aids to Trade

Aids to trade are auxiliary services that support the process of trade. These include:

• Transportation: Movement of goods from producers to consumers.
• Warehousing: Storage of goods to ensure steady supply.
• Banking: Providing financial support through loans, credit, and transactions.
• Insurance: Protection against risks such as damage or loss.
• Advertising: Promoting goods and services to attract customers.

3. Service Sector

The service sector focuses on providing intangible value through expertise, assistance, and support to businesses and individuals. It can be divided into:

(a) Professional Services

These include specialized services provided by experts in fields like law, accounting, consultancy, and medicine.

(b) Personal Services

Services tailored to individual needs, such as salons, spas, and fitness centers.

(c) Public Utility Services

Essential services like water supply, electricity, and public transport provided for the benefit of the general population.

(d) Financial Services

These encompass banking, investment, insurance, and capital market services that support economic growth.

(e) IT and Technology Services

With digital transformation, IT services, software development, and technology solutions have become integral to modern business activities.

Interdependence of Business Activities

The three categories of business activities—industry, commerce, and service—are interdependent and complement each other to ensure the smooth functioning of the economy:

• Industries produce goods that commerce distributes and services enhance.
• Commerce facilitates the exchange of industrial products and provides services to improve market efficiency.
• Services support both industries and commerce by addressing operational and consumer needs.

Importance of Classifying Business Activities:

• Specialization: Classification helps businesses specialize and focus on core competencies.
• Resource Allocation: Efficient use of resources by identifying needs in each category.
• Policy Making: Governments can frame better policies by understanding the roles of different sectors.
• Economic Analysis: Classification provides insights into the economic contribution of each sector, aiding in growth strategies.

The Law of demand asserts that, all else being equal, as the price of a good or service rises, the quantity demanded typically decreases, and as the price falls, the quantity demanded increases. While this law is generally valid in most market situations, there are certain exceptions where the demand curve does not follow this standard behavior.

1. Giffen Goods

Giffen goods are a class of inferior goods that do not follow the law of demand. These goods typically see an increase in quantity demanded as their price rises and a decrease in quantity demanded when their price falls. This counter-intuitive phenomenon occurs because the income effect outweighs the substitution effect. Giffen goods are usually staple items that make up a large portion of the consumer’s budget, such as bread or rice in impoverished regions.

When the price of a Giffen good rises, consumers’ real income effectively decreases, causing them to buy more of the good despite its higher price, because they can no longer afford the more expensive alternatives. A classic example is the situation in some developing countries where, if the price of rice rises, poor consumers may cut back on other foods but buy more rice because it is still their most affordable option.

2. Veblen Goods

Veblen goods are a category of goods for which demand increases as the price rises, contradicting the law of demand. These are typically luxury goods or status-symbol items, such as designer clothing, high-end cars, or expensive watches. The higher price of these goods actually makes them more desirable because consumers perceive them as exclusive, prestigious, or a status symbol. The desire to signal wealth and status to others causes demand to rise when the price increases. Essentially, consumers view these goods as more valuable because they are expensive, which is why the law of demand does not hold in this case.

For example, as the price of a luxury brand like Rolex increases, some consumers might perceive the watch as more prestigious and, therefore, may desire it more, increasing the quantity demanded.

3. Speculative Bubbles

In certain markets, particularly in asset markets like real estate, stocks, or commodities, the law of demand may not apply due to speculative bubbles. A speculative bubble occurs when the price of an asset rises due to excessive demand driven by the belief that prices will continue to rise in the future. In such cases, an increase in price may actually lead to an increase in demand, as consumers or investors expect to profit from future price increases. People are willing to buy at higher prices with the expectation of selling at even higher prices later.

For example, during a housing bubble, rising home prices may cause more buyers to enter the market, as they believe the prices will continue to climb, and they want to secure a home before they become even more expensive.

4. Essential Goods (Necessities)

For essential goods or necessities, such as basic food items, healthcare, and utilities, the law of demand may not hold strongly, particularly for low-income consumers. When the price of these goods rises, consumers might not reduce their quantity demanded as expected because these goods are vital for survival. As these goods are non-substitutable and necessary for day-to-day living, consumers may continue to purchase them, even at higher prices, to meet their basic needs.

For example, if the price of basic medications increases, people with chronic conditions may still buy the medicine because it is necessary for their health, leading to inelastic demand, where the quantity demanded doesn’t change much with price fluctuations.

5. Price Expectations

In certain circumstances, future price expectations can cause an increase in demand when prices rise. If consumers expect that prices will increase further in the future, they may choose to purchase more of a good or service now, even if the price has already increased. This is particularly common with durable goods like cars or electronics. The expectation of future price hikes leads consumers to buy more at current prices to avoid higher costs later, thereby causing an increase in demand.

For instance, if a consumer expects gasoline prices to rise sharply in the near future, they might fill up their tanks even if the price has already increased, leading to higher demand at the higher price.

6. Dynamic Pricing and Popularity

In some markets, particularly those involving dynamic pricing, demand might increase when the price increases due to a boost in the perceived value of the product. This is often the case with concert tickets, airline tickets, or hotel bookings, where prices increase as the event or service gets closer. Higher prices in these cases may increase demand, as consumers perceive the product or event as being more exclusive or in limited supply.

For example, tickets for a popular concert may become more expensive as the date approaches, and this increase in price could actually spur demand as consumers want to secure tickets before they are sold out.

7. Psychological Pricing

Psychological pricing is another factor where demand may increase despite higher prices. This happens when products are priced in a way that creates a perception of greater value, such as pricing an item at $9.99 instead of $10. This small price difference can make the product seem like a better deal, encouraging consumers to buy more, even though the price has increased slightly. This behavior exploits consumer psychology and is often used in retail and marketing strategies.

Business is an organized entity that engages in the production, distribution, and sale of goods or services to satisfy the needs and wants of consumers, typically with the aim of earning profit. It involves activities like planning, marketing, finance, and operations management. Businesses operate within a dynamic environment influenced by economic, social, technological, and legal factors. They can take various forms, including sole proprietorships, partnerships, corporations, and cooperatives. Successful businesses align their goals with market demands, adapt to changes, and focus on creating value for stakeholders, including customers, employees, and investors, while maintaining ethical and sustainable practices.

Supply refers to the quantity of a good or service that producers are willing and able to offer for sale in the market at various prices over a specific period of time. It is a fundamental concept in economics that reflects the relationship between price and the quantity supplied. Generally, supply increases with rising prices because higher prices provide greater incentives for producers to produce more, while supply decreases when prices fall.

Determinants of Supply:

Supply is influenced by several factors, known as the determinants of supply. These factors determine the quantity of goods or services that producers are willing to offer in the market at various price levels. Understanding these determinants is crucial for analyzing market dynamics and predicting changes in supply.

1. Price of the Good

The price of a good is the most significant determinant of supply. As prices increase, producers are incentivized to supply more of the good to maximize profits, and vice versa. This direct relationship between price and supply is the basis of the law of supply.

2. Cost of Production

The cost of production, including raw materials, labor, and overheads, directly affects supply. Lower production costs enable producers to supply more at the same price, while higher costs reduce supply. For example, a decrease in the price of raw materials allows firms to produce goods more economically, increasing supply.

3. Technology

Advancements in technology enhance production efficiency and reduce costs, leading to an increase in supply. Technological innovations enable faster and higher-quality production, often at lower costs. For instance, automation in manufacturing industries has significantly boosted supply.

4. Government Policies

Policies such as taxes, subsidies, and regulations impact supply.

• • Taxes increase production costs, reducing supply.
  • Subsidies lower costs, encouraging producers to supply more.

Regulations, such as environmental laws or safety standards, may restrict supply by imposing additional compliance costs.

5. Prices of Related Goods

If producers can switch between products, the prices of related goods affect supply. For example, if the price of corn rises, farmers might allocate more resources to grow corn instead of wheat, reducing the supply of wheat.

6. Number of Producers

An increase in the number of producers in a market typically increases overall supply. Conversely, if firms exit the market due to losses or other factors, supply decreases.

7. Expectations of Future Prices

If producers expect prices to rise in the future, they may withhold current supply, reducing it temporarily. Conversely, if prices are expected to fall, producers may increase supply to sell before the price drops.

8. Natural and External Factors

Events like natural disasters, climate conditions, and global crises can disrupt production and affect supply. For example, droughts reduce the supply of agricultural products, while favorable weather conditions boost it.

Law of Supply:

Law of Supply is a fundamental principle in economics that describes the relationship between the price of a good or service and the quantity supplied, assuming all other factors remain constant (ceteris paribus). It states that as the price of a good increases, the quantity supplied also increases, and conversely, as the price decreases, the quantity supplied decreases. This positive correlation arises because higher prices provide greater incentives for producers to increase production to maximize profits.

Key Assumptions of the Law of Supply

• Ceteris Paribus Condition

Other factors affecting supply, such as technology, production costs, or government policies, remain constant.

• Rational Behavior of Producers

Producers aim to maximize their profits by supplying more at higher prices.

• No Change in Market Conditions

Market conditions like consumer preferences, competition, or input prices are stable.

Explanation with Example

Suppose the price of oranges increases from $2 to $4 per kilogram:

• At $2 per kilogram, farmers supply 500 kilograms.
• When the price rises to $4 per kilogram, farmers supply 1,000 kilograms.

This increase in supply reflects producers’ willingness to produce more at higher prices due to higher profit margins.

Graphical Representation

The supply curve, typically upward-sloping, illustrates the law of supply.

• X-axis: Quantity supplied
• Y-axis: Price of the good

The curve shows that as price increases, quantity supplied rises, demonstrating a direct relationship.

Exceptions to the Law of Supply

• Perishable Goods

Producers may sell all their stock, irrespective of price, to avoid spoilage.

• Future Expectations

If producers expect prices to rise, they might withhold supply temporarily.

• Fixed Supply Situations

In cases like antiques or natural resources, the supply cannot increase regardless of price.

• Market Constraints

Producers may face resource or capacity limits, preventing them from increasing supply.

Importance of the Law of Supply:

• Pricing Decisions

Helps businesses determine pricing strategies based on supply responsiveness.

• Market Equilibrium

Works with the law of demand to establish equilibrium price and quantity in the market.

• Policy Formulation

Guides governments in crafting policies like subsidies or price controls.

Joint Stock company is a voluntary association formed for the purpose of carrying on some business. Legally, it is an artificial person and having a distinctive name and a common seal. Lord Justice Lindley of England has defined joint-stock company as “an association of many persons who contribute money or moneys’ worth to a common stock and employ it for a common purpose.

The common stock so contributed is denoted in money and is the capital of the company. The persons who contribute it or to whom it belongs are members. The proportion of capital to which each member is entitled is his share.”

The term “joint stock company” has been defined by the Companies Act in India as a company limited by shares having a permanent paid-up or nominal share capital of fixed amount divided into shares, also of fixed amount held and transferable as stock, and formed on the principle of having in its members only the holders of those shares or stock and other persons.”

The important features of a joint stock company are the following – an artificial person created by law, with a distinctive name, a common seal, a common capital with limited liability, and with a perpetual succession. An analysis of the above definition reveals many distinctive features of joint-stock company, which distinguish it from other forms of business organization.

Features of Joint Stock Company

1. Separate Legal Entity

A joint stock company has a separate legal existence apart from the persons composing it. It can own property and sue in a court of law. A shareholder being an entity distinct from that of a company can sue the company and be sued by it whereas a partnership organization or a sole proprietor has no such legal existence in the eye of the law, separately from the persons composing it. Hence there can’t be a contract between a partner and the firm whereas there can be a contract between a shareholder and a company.

2. Perpetuity

A joint-stock company has the characteristic of perpetuity unlike a partnership or a sole trading concern. Once, a company is formed, it continues for an unlimited period until it is formally liquidated. The maxim “men may come and men go but I go on forever” applies in the case of the company. But a sole trading concern comes to an end with the death of a sole trader, and in the case of partnership, death, retirement, or insolvency of any member of the partnership would dissolve the firm.

3. Limited Liability

In the case of joint-stock company the liability of members is normally limited by guarantee or by the shares he has taken. If a member has already paid the complete amount due on his shares, he is not further liable towards the debts of the company. But in the case of sole proprietorship and partnership, the liability is unlimited and in the case of the latter, it is also both joint and several.

4. Number of Members

In the case of public limited company the maximum number of members is unlimited, the minimum being seven. In the case of a private limited company, the maximum is two. But the number of partners in a partnership cannot exceed ten in the case of business and twenty in other lines of business.

5. Separation of Ownership from Management

In the case of partnership, partners are not only the owners of the business but they take part its management also. Every member of a partnership firm is an agent of the firm and also of the other members. In the case of joint-stock company, the shareholders are the owners while the management is entrusted to a board of directors, who are separate from shareholders.

6. Transferability of Shares

The shareholder of a company can transfer his shares to others without consulting other shareholders, whereas in a partnership a partner cannot transfer his share without the consent of all the other partners.

7. Rigidity of Objects

In the case of partnership, the scope of its business can be changed at any time with the consent of all the partners, whereas a joint stock company cannot do any business not already included in the object clause of the Memorandum of Association of the company. A change in the object clause under condition laid down in the Companies Act is essential for making any alteration in the scope of the business.

8. Financial Resources

On account of liability and diffusion of ownership in joint company organization, there is a great scope for mobilizing a large capital. But in the case of partnership or sole proprietorship, because of the limited number of members, the resources at their command are limited.

9. Statutory Regulation

A company has to comply with numerous and varied statutory requirements. It has to submit a number of returns to the government, whereas partnership and sole proprietorship are free from much State control and statutory regulations. Further in the case of the company, accounts must be audited by a charted accountant but it is not compulsory in the case of partnership and sole proprietorship.

Advantages of Joint Stock Company

1. Financial Strength

The joint stock company can raise a large amount of capital by issuing shares and debentures to the public. There is no limit to the number of shareholders in a company. (However, in a private company the membership cannot exceed 50.) The capital of the company is divided into numerous parts of small value called shares and this attracts even the person with limited resources.

Further, anyone can purchase the shares and leave the responsibility of management to the body of persons called directors. Again, as the shares are freely transferred by selling it in the stock market, this works as an added attraction to the investors. Because of this, the joint stock form of organization is well adopted for raising amounts of capital.

2. Limited Liability

One important factor which attracts the investors to subscribe is the principle of limited liability. According to this a shareholder’s liability is limited only to the extent of the face value of the shares held by him and his personal properties are not affected. This form of organization is a great attraction to persons who do not want to take much risk in other forms of organization that do not enjoy the benefit of limited liability.

3. Benefits of Large Scale Organization

As the size of a company is large, the economies of large-scale organization and production are secured. Due to this, the cost of production will be less and the society is in a position to get its requirements at a lesser price.

4. Scope for Expansion

As there is no limit to the number of persons in a company, there is a great scope for expansion of the business. A company, which is making good profits, can create big reserves which can be used for the expansion of the company. In addition, the availability of managerial talent in the company facilitates the expansion of the business.

5. Stability

A company is a legal entity and enjoys perpetual succession which means the retirement or death of a shareholder cannot affect the company Even the change in the management or the owner or disputes over the ownership of shares or stock cannot affect the continuity of a company. The companies are well suited for business, which require a long period to establish and consolidate.

6. Transferability of Shares

One special feature of company is that shares are freely transferable from one person to another without the knowledge of the shareholders. The existence of stock exchanges where shares and debentures are sold and purchased has facilitated as good as cash as they can be sold at any time and there is an added attraction to the investors.

7. Efficient Management

In company organizations, the agents of production are effectively combined and also there is scope for increased efficiency of direction and management. The most efficient persons may be chosen as directors and if found indifferent, they may be changed in the next meeting. Normally, as the directors have a great stake in the business, in the interest of the company, and in their own interest, they have to be very efficient.

8. Higher Profit

As a large capital is invested in companies, it would be possible for them to use the expensive machinery and up-to-date equipment resulting in greater production, reduced cost, and higher profit. The progress of industries and commerce of the nation.

9. Diffused Risk

In this form of organization, the risk is reduced for each shareholder, because it is diffused and spread over several shareholders of the company. This is an advantage from the individual investor’s point of view.

10. Bolder Management

In this form of organization, as the persons who manage the company have relatively smaller financial stake, they can become adventurous. There are many industries, which would not have come into existence if people had been unduly cautious.

Starting of a new enterprise needs an adventurous spirit and in case of joint-stock company because of its limited liability and smaller financial stake of the persons, who manage it, people can become adventurous and thus start new enterprises.

11. Social Benefit

The company form of organization has encouraged the habit of saving and investment among the public. It has also indirectly helped the growth of financial institutions such as banks and insurance companies by providing avenues to invest their funds. Further, as companies cannot be managed by all the shareholders who are large in number, it has to employ professional managerial personnel and this has helped the development of management as a profession.

Disadvantages of Joint-Stock Company

1. Formation is Difficult

The formation of a company involves a long-drawn-out complex procedure. For formation many provisions of the Companies Act are be complied with. Large amount of money have to be spent in order to fulfill the preliminaries. Further, in many cases government sanction is required. These difficulties discourage many persons from starting companies.

2. Fraudulent Management

Many a time unscrupulous promoters by presenting the prospectus as a rosy picture manage to get capital from the public. This results in companies being started and managed by incapable and fraudulent hands.

3. Concentration of Control in Few Hands

In theory, democratic principles are followed in the management of companies, but in practice it is nothing but oligarchy of managing director and directors leading to concentration of control in a few hands. The shareholders have no say in the affairs of the company.

As they are spread throughout the country, very few care to attend the meetings and those who do not attend, normally give proxies in favor of managing director or directors. All these facilitate the concentration of economic power in the hands of a few persons.

4. Encourages Speculation

This form of organization encourages speculation on the stock exchange. Usually the value of the company’s share depends on the dividends declared and reputation of the company, which can be manipulated. This may encourage the managing director and directors to manipulate the shares on the stock exchange in their own interest to the detriment of the majority of shareholders.

5. Lacks Initiative and Motivation

As there is indirect delegated management in the company form of organization, there is no initiative and motivation. The paid officials who manage the company have no personal interest and this leads to inefficiency and waste.

6. Conflict of Interest

There is a conflict of interest between persons who are at the helm of affairs of company and shareholders. Many times dishonest persons at the top succeed in cleverly misleading and cheating the shareholders. Again there is a clash of interest between the shareholders.

Again there is a clash of interest between the preference shareholders and equity shareholders. While the preference shareholders want the creation of large reserves out of profits, the equity shareholders are interested in distributing the entire profit by way of dividends.

7. Excessive Government Control

A company form of organization is very much controlled by the government and it has to observe many provisions of the different regulations of the government. Again, heavy penalty is imposed for the non-observance of the provisions of the Acts. Companies spend much of their precious time in complying with the provisions and the statutory rules.

8. Lack of Prompt Decision

The prompt decisions which are possible in case of other organizations such as sole-trading organization and partnership are not possible in a company form of organization. Owing to the difficulty of getting the requisite quorum and the presence of diverse interests, which may lead to disagreement, prompt decision cannot be taken.

9. Monopolistic Control

There is a great possibility for companies to form combination or amalgamate with a view to getting monopolistic control. This is very harmful to the other producers and businessmen in the same line and also to the consumers.

Definitely, if there is any change in supply, demand or both the market equilibrium would change. Let’s recollect the factors that induce changes in demand and supply:

Shift in Demand

The demand for a product changes due to an alteration in any of the following factors:

• Price of complementary goods
• Price of substitute goods
• Income
• Tastes and preferences
• An expectation of change in the price in future
• Population

Shift in Supply

The supply of product changes due to an alteration in any of the following factors:

• Prices of factors of production
• Prices of other goods
• State of technology
• Taxation policy
• An expectation of change in price in future
• Goals of the firm
• Number of firms

Now let us study individually how market equilibrium changes when only demand changes, only supply changes and when both demand and supply change.

When only Demand Changes

A change in demand can be recorded as either an increase or a decrease. Note that in this case there is a shift in the demand curve.

(i) Increase in Demand

When there is an increase in demand, with no change in supply, the demand curve tends to shift rightwards. As the demand increases, a condition of excess demand occurs at the old equilibrium price. This leads to an increase in competition among the buyers, which in turn pushes up the price.

• Shifts in Demand and Supply
• Equilibrium, Excess Demand and Supply

Of course, as price increases, it serves as an incentive for suppliers to increase supply and also leads to a fall in demand. It is important to realize that these processes continue to operate until a new equilibrium is established. Effectively, there is an increase in both the equilibrium price and quantity.

(ii) Decrease in Demand

Under conditions of a decrease in demand, with no change in supply, the demand curve shifts towards left. When demand decreases, a condition of excess supply is built at the old equilibrium level. This leads to an increase in competition among the sellers to sell their produce, which obviously decreases the price.

Now as for price decreases, more consumers start demanding the good or service. Observably, this decrease in price leads to a fall in supply and a rise in demand. This counter mechanism continues until the conditions of excess supply are wiped out at the old equilibrium level and a new equilibrium is established. Effectively, there is a decrease in both the equilibrium price and quantity.

When only Supply Changes

A change in supply can be noted as either an increase or a decrease. Note that in this case there is a shift in the supply curve.

(i) Increase in Supply

When supply increases, accompanied by no change in demand, the supply curve shift towards the right. When supply increases, a condition of excess supply arises at the old equilibrium level. This induces competition among the sellers to sell their supply, which in turn decreases the price.

This decrease in price, in turn, leads to a fall in supply and a rise in demand. These processes operate until a new equilibrium level is attained. Lastly, such conditions are marked by a decrease in price and an increase in quantity.

(ii) Decrease in Supply

When the supply decreases, accompanied by no change in demand, there is a leftward shift of the supply curve. As supply decreases, a condition of excess demand is created at the old equilibrium level. Effectively there is increased competition among the buyers, which obviously leads to a rise in the price.

An increase in price is accompanied by a decrease in demand and an increase in supply. This continues until a new equilibrium level is attained. Further, there is a rise in equilibrium price but a fall in equilibrium quantity.

When both Demand and Supply Change

Generally, the market situation is more complex than the above-mentioned cases. That means, generally, supply and demand do not change in an individual manner. There is a simultaneous change in both entities. This gives birth to four cases:

• Both demand and supply decrease
• Both demand and supply increase
• Demand decreases but supply increases
• Demand increases but supply decreases

(i) Both Demand and Supply Decrease

The final market conditions can be determined only by a deduction of the magnitude of the decrease in both demand and supply. In fact, both the demand and supply curve shift towards the left. Essentially, there is a need to compare their magnitudes. Such conditions are better analyzed by dividing this case further into three:

The decrease in demand = decrease in supply

When the magnitudes of the decrease in both demand and supply are equal, it leads to a proportionate shift of both demand and supply curve. Consequently, the equilibrium price remains the same but there is a decrease in the equilibrium quantity.

The decrease in demand > decrease in supply

When the decrease in demand is greater than the decrease in supply, the demand curve shifts more towards left relative to the supply curve. Effectively, there is a fall in both equilibrium quantity and price.

The decrease in demand < decrease in supply

In a case in which the decrease in demand is smaller than the decrease in supply, the leftward shift of the demand curve is less than the leftward shift of the supply curve. Notably, there is a rise in equilibrium price accompanied by a fall in equilibrium quantity.

(ii) Both Demand and Supply Increase

In such a condition both demand and supply shift rightwards. So, in order to study changes in market equilibrium, we need to compare the increase in both entities and then conclude accordingly. Such a condition is further studied better with the help of the following three cases:

The increase in demand = increase in supply

If the increase in both demand and supply is exactly equal, there occurs a proportionate shift in the demand and supply curve. Consequently, the equilibrium price remains the same. However, the equilibrium quantity rises.

The increase in demand > increase in supply

In such a case, the right shift of the demand curve is more relative to that of the supply curve. Effectively, both equilibrium price and quantity tend to increase.

The increase in demand < increase in supply

When the increase is demand is less than the increase in supply, the right shift of the demand curve is less than the right shift of supply curve. In this case, the equilibrium price falls whereas the equilibrium quantity rises.

(iii) Demand Decreases but Supply Increases

This condition translates to the fact that the demand curve shifts leftwards whereas the supply curve shifts rightwards. As they move in opposite directions, the final market conditions are deduced by pointing out the magnitude of their shifts. Here, three cases further arise which are as follows:

The decrease in demand = increase in supply

In this case, although the two curves move in opposite directions, the magnitudes of their shifts is effectively the same. As a result, the equilibrium quantity remains the same but the equilibrium price falls.

The decrease in demand > increase in supply

When the decrease in demand is greater than the increase in supply, the relative shift of demand curve is proportionately more than the supply curve. Effectively, both the equilibrium quantity and price fall.

The decrease in demand < increase in supply

Here, the leftward shift of the demand curve is less than the rightward shift of the supply curve. It is important to realize, that the equilibrium quantity rises whereas the equilibrium price falls.

(iv) Demand Increases but Supply Decreases

Similar to the aforementioned condition, here also the demand and supply curve moves in the opposite directions. However, the demand curve shift towards the right(indicating an increase in demand) and the supply curve shift towards left(indicating a decrease in supply). Further, this is studied with the help of the following three cases:

Increase in demand = decrease in supply

When the increase in demand is equal to the decrease in supply, the shifts in both supply and demand curves are proportionately equal. Effectively, the equilibrium quantity remains the same however the equilibrium price rises.

Increase in demand > decrease in supply

In this case, the right shift of the demand curve is proportionately more than the leftward shift of the supply curve. Hence, both equilibrium quantity and price rise.

Increase in demand < decrease in supply

If the increase in demand is less than the decrease in supply, the shift of the demand curve tends to be less than that of the supply curve. Effectively, equilibrium quantity falls whereas the equilibrium price rises.
