[Commerce Class Notes] on Supply Function Pdf for Exam

Definition of Supply Function

A supply function is a tool used by economists to measure the relationship between price and quantity of goods supplied. The supply function describes the effect that changes in one variable have on another. Supply function can be described with three variables: Price, Quantity Supplied, and Marginal Cost. The supply function is also known as Supply Curve. The Supply Curve is a graphical representation of the Law of Supply. It shows the relationship between price and quantity supplied at a given point in time. The curve slopes upward because as price increases, producers are able to sell more units of the good or service. The marginal cost curve intersects the supply curve at the equilibrium point. This is where quantity supplied equals quantity demanded. The marginal cost curve measures the change in total costs associated with producing one more unit of output. At the equilibrium point, marginal cost is equal to price.

Importance of Supply function

The supply function is important to study because it shows the relationship between two variables. The supply function can be used to illustrate how demand changes when the price is altered, and vice versa. Supply functions are often depicted graphically with a supply curve that slopes upward because as prices increase producers will be able to sell more units of goods or services. Supply curves serve an important role in economic theory by showing what happens to overall production levels based on current market conditions such as supply & demand trends, technology improvements, etc.

Supply Function is Applied in Various Fields

  1. Supply function is an integral part of microeconomics, which deals with the behavior and decision-making process of individuals and firms in society. The supply function is used to measure price elasticity demand for goods & services. The concept helps economists predict how much quantity will be produced by producers when prices change.

  2. Supply function is also used in macroeconomics, which deals with the performance, structure, and behavior of an economy as a whole. Supply functions help policymakers understand how shocks to the economy (such as changes in tax rates or government spending) will impact things like employment levels and inflation.

  3. Supply function is used in business, to help managers understand how costs and prices impact their production levels. The supply curve can be helpful in forecasting future sales and making pricing decisions.

  4. Supply function is also used in agricultural economics, which deals with land usage and food production. Supply functions can help assess how policies impact the price of crops or livestock over time.

  5. Supply function is also used in natural sciences, for example, to determine the effect of temperature changes on tiny organisms or chemicals. Supply functions can help scientists understand how biological specimens react when they are exposed to new conditions such as heat or cold.

[Commerce Class Notes] on Time and Place of Performance of Contract Pdf for Exam

A contract to be performed should be in a definite time and place. This is done to attract the legal objectives of a contract. Parties contracting under this agreement need to perform according to the set time and place to remain valid under the Indian Contract Act.

Further knowledge is needed to be acquired in this subject matter of discussion.

Time and Place of Performance of Contract

As known a promisor and a promisee are the two essentials to a contract, and equally important is the time and place where the contract is to be performed. Given the time and place of the contract to be performed are already agreed upon, then the promisor is liable to perform the promise accordingly. If not, then he should perform the same at a reasonable place and time. The Indian Contract Act, 1872, specifies some rules regarding this time and place for the performance of the contract under the sections between 46 – 50.

When No Application to be made and Also No Time specified 

A contract where the promisor has to perform his promise without any application by the promisee and there is no predetermined time specified for the performance of the same. In such a circumstance, the promisor should perform the contract at a reasonable time. Here the term ‘reasonable’ is interpreted differently. The section specifies that the circumstances of every case will be analysed for the definition of ‘reasonable time’ for the parties involved.

Example: Mona promises to pay Miller Rs 5,000 in cash at his house, within six months, as a repayment of the loan he had taken from Miller. Mona leaves for work at six in the morning which is when Miller returns home from his night shift job. As per the circumstances, the only time when Mona and Miller can meet is at six in the morning. Hence, the time for the performance of the contract is 6 a.m. and the place is at Miller’s house.

Further, if there is a contract where the promisee is not mandated to make an application but the promisor needs to perform the contract only on a Sunday, then the promisor will have to perform such promise during regular business hours, provided the time is specified in the contract too.

Example: Pam promises to deliver certain goods to Jim on payment of an advance of Rs 5,000. Jim makes the payment and asks Pam to deliver the goods on a Sunday. Since the time is not specified, Pam should deliver it between 9 am and 6 pm, the assumption that those are the regular business hours in the place where they reside.

If Pam attempts delivery after the business hours, then Jim has the right to not accept the goods and ask Pam to deliver again during the usual business hours.

Application by the Promisee required 

When there is a contract where the promisee is required to make an application for the performance of a contract, then the promisee needs to ensure that the application is made by him at a proper place and time. In this case, the phrase ‘proper place and time’ will hold wide meanings in different situations.

Like in the example of Pam and Jim, they both enter a contract where Pam promises to fix Jim’s car whenever he asks him to. Pam also takes an advance payment for the same. When Jim asks Pam to fix his car, he needs to ensure that he doesn’t ask Pam to go a lot out of his way. Also, he must preferably ask for repairs during business hours.

When No Application to be made But the Place of Performance is not specified

A contract where the promisee is not necessitated to make an application for the performance of the contract. Also, the place of performance is not specified. In this scenario, the total responsibility of the promisor to apply to the promisee asking him to appoint a reasonable place for the performance of such promise.

Example: Rik promises to deliver 5 audio sets to Mark. On an already fixed day and time. However, the contract does not mention the address for the performance. It is Rik’s responsibility to apply to Mark and ask him to appoint a reasonable place where he can safely accept the delivery of the ordered goods.

Performance as Such prescribed by the Promisee

There is also a chance for a contract to take place, where the promisor agrees to perform the promise in a manner already mentioned and at a place and time prescribed by the promisee.

Solved Example on Performance of Contract

1. Pit owes Rs 5,000 to Jack. According to the agreement between them, Jack doesn’t need to make an application for Pit to repay the loan. Also, there is no mention of either time or place. Further, Pit has agreed to repay the money in a manner and at a place and time prescribed by Jack.

One day Jack visits Pit’s house and takes a liking for a new painting made by Pit. He asks Pit to give him the painting instead of the loan. Pit obliges and does the necessary paperwork. Has Pit repaid his loan?

Ans: According to Section 50 of the Indian Contract Act, 1872, Pit has performed his promise in a manner and at a place and time prescribed by the promisee, Jack.

Jack asked for the painting as a repayment of the loan. Here he exercised his right to devise the manner of the performance of the promise. Since Pit obliged, he had legally fulfilled the contract and was no longer liable to pay any further money to Jack.

Attaching time and place is essential for a valid contract and hence this is to be borne in the mind of the contracting parties.

Sections & Performance of Contract

Section 46

Section 46 there is no period mentioned and also know application Is made by the promisee. And hence in such cases, the promisor must priorly inform the work to be done within a reasonable time

Section 47

In section 47, the time and place of performance of the contract are mentioned. However, there is no application made by the promisee.  ancient and if there is no time mentioned then the promisor is liable to deliver the services promised within usual hours of the business.

Section 48

In section 48, the performance is to be made at a specified time and place, but there must be an application created by the promisee to the promisor. In this contract, the promisor will only fulfil the services, when the promisee makes an application on the specified day. Also, the promisee must request the promisor to complete the services of performance of the contract time and place.

 

Section 49

In section 49, there is no place fixed for the services and no application is to be made to the promisor by the promisee. That means no place is been mentioned for the services to be delivered and there’s not even an application made. And hence in such cases, it is the duty of the promisor to request of promisee of a place to deliver the goods or services accordingly 

Section 50

In section 50, the services mentioned have to be made in time and manner as it is specified by the promisee in the contract. Also, this contract can work in which the promisor agrees to perform the contract at the place and time, promised by the promisee.

[Commerce Class Notes] on Trial Balance Format Pdf for Exam

A trial balance is an accounting or bookkeeping report that lists balances from a company’s general ledger accounts. The debit balances ‘and the credit balances are listed under their respective fields. The sum of these columns should be the same.

[Commerce Class Notes] on Types of Economy Pdf for Exam

The economy is a major part of our life. The economy has been prevalent in our system since time immemorial. Decades long, we have come through many types of economic structures which have their own system of accommodation and planning. It is important for us to know the varied form of economies that plays a fundamental base in our upgrowth.

In this context, we are going to study the basics of the economic system and the types of an economy that prevailed and is prevailing.

Economic System Definition

Economic systems are the means that are adopted by governments of respective countries for the distribution of resources along with services and goods. Such an arrangement is dependent on production factors – capital, labour, physical resources, entrepreneurs, and information resources.

Types of Economy 

There are four types of economic systems –

  1. Traditional Economic System 

This economic system retains essential characteristics in which there is a very little specialisation or division of labour.

A traditional economic system is most likely to be found in rural settings, or in such developing nations where farming is predominant. Such settings usually have very few resources to share.

  1. Command Economic System 

Command or Socialist economic system has a dominant centralised authority in the form of government. The economy is such a country that is controlled by the government. It is the sole decision-making authority for determining production and allocation.

Ideally, the command system takes into consideration the best interest of its populace.

  1. Market Economic System

A market economic system or capitalist economy involves very less government interference and incorporates the principles of the free market. There is a scant exercise of control over resources. Market forces regulate demand and supply.

However, there does exist some degree of government intervention in the form of regulations against monopoly, and in favour of fair trade.

  1. Mixed Economic System 

A mixed economic system combines the features of both socialist and free-market economic systems. It is also known as a dual system. Most of the countries today have a mixed economic system with the existence of both public services as well as private industries.

Difference between Types of Economy 

The difference between the types of economies are as follows:

Parameters

Market Economic System

Command Economic System

Mixed Economic System

Determination of price 

Demand and supply in a market determine the price

The central authority, most likely the government, decides the prices of goods and services 

Price is influenced by market forces of demand and supply as well as government regulations, in certain instances 

Property ownership 

Ownership vests with private entities 

There is public ownership of property 

Property is owned by both public and private entities 

Production 

Production is undertaken only with a profit motive

The underlying objective of production is social welfare

Production in a mixed economy includes both profit motive and social welfare 

Competition 

There exists competition among entities present in such market 

There is no competition in a market owing to State ownership of firms. 

Only entities in the private sector experience competition 

Government intervention 

Government has very little role to play in a market economic system 

The government retains full control over firms 

Government has a full holding in the public sector but a limited role in its private counterpart

Economic Sectors

These can be categorised into the following –

1. Primary Sector 

The primary sector in an economy has a direct interface with the environment for purposes of production. Instances of the primary sector are agriculture, farming, mining, and fishing, among others.

The importance of the primary sector relates to the harvesting of products or extraction from the environment for procuring basic food and raw material. The end purpose of the primary sector is to utilise natural resources optimally.

2. Secondary Sector 

In the secondary sector of an economy, raw materials are converted into products that are fit for both consumption or sale and help to move away from a primitive economic system. For example, the secondary sector helps a country to move from agriculture or other similar activities towards a developing market.

In India, the secondary sector holds about 20% of the gross domestic product. It helps to provide greater job opportunities to the populace at large.

3. Tertiary Sector 

The Tertiary sector primarily covers the service sector, and therefore, focuses on service exchanges and production. Examples of the tertiary sector are – insurance, banking, communication and transportation, among others.

The tertiary sector’s significance is on the rise due to rapid technological developments in various basic essential services. These basic services include healthcare, police, banking, etc.

The most significant benefit of the tertiary sector is that it has a lower barrier of entry for businesses.

Economic liberalisation in India was initiated in 1991, and Dr Manmohan Singh was the pioneer of this liberalisation.

In economic liberalisation, government restrictions and regulations are reduced to facilitate the participation of private entities to a much greater extent. It is an inherent principle in Classical Liberalism. “Controls” were removed to drive economic development, which was in a rocky state.

The liberalisation of the Indian economy provided access to foreign investors, which subsequently increased foreign trade. Such changes went on to create higher job opportunities for the people of India.

[Commerce Class Notes] on Under and Over Subscription Pdf for Exam

A company receives applications for more shares than what is offered to the public for subscription. This situation is termed as Over Subscription of shares. However, allotment can be only made to the number of shares that have been issued. The company is not allowed to allot more shares than the issued number even if there is a demand for that particular share. Over Subscription of shares is a situation where the buyers show interest in a new stock for which demand exceeds supply. Before the issue of new shares, the number of potential investors is calculated by the study of the market by underwriters. Based on such calculations of people who may or may not purchase such shares, the company issues a fixed number of shares. 

What is a Subscription of Shares?

Companies or enterprises are the driving force of an economy. They create real value in terms of goods and services for the betterment of the society they serve. Establishing a company or any business requires an initial amount of money as capital. The sheer amount of money required to start any business is often not possible to arrange for an individual or even by a small group of investors for that matter. In such situations, there are some other options available by which they can plan and step ahead in their endeavor. Besides getting a loan from the banking institutions the other suitable option is calling people with money to invest to come together. In this process, the distributed resources are pulled together by the owners for better utilization by establishing a business unit. They are known as the shareholders and are promised a share of profit in proportion to their money invested. 

In a traditional way, this is achieved by offering shares to the interested buyers before the establishment of the company. The individuals with the plan of starting a business estimate the required capital that is needed to be procured from the public. After surveying the expected number of buyers in the market they decide the number of shares to be created. These shares are underwritten with the determined value and are issued in an IPO. Shares can also be created after the establishment of a business also. An expansion of the business or for increasing the capacity also needs more capital so it can also be met either by getting a loan or providing shares.

After the offer of shares 3 things can happen. There can be optimum buyers as per the shares offered which is an idle situation to be expected. Contrarily the buyers can be either more than the shares offered or can be less. When applicants buy more with respect to the shares issued then this condition is known as oversubscription. And if the applicants are less than the total shares issued such a condition is known as under subscription.
