    Individual economic unit
  • b)
      Mixed economies
  • c)
      Individual economy 
  • d)
    Planned economies

I. The term Micro Economics is derived from the Greek work “Mikros” which means “Small”. Micro economics gives a detailed analysis of one part of the economy or society. It studies the behaviour of individual units of the economy, such as households, firms, industries and markets.ii. Micro economics is concerned with the study of behaviour of individual element(s) of an economy, whereas, macro economies concerned with the study of behaviours of an economy as whole.iii. Micro-economics gives a microscopic picture of the economy. The activities of numerous economic units and their inter-relationship are studied and analysed minutely through this method.

       As they should be
  • b)
      As they are
  • c)
      As they are expected
  • d)
      As they seem to be
Correct answer is option 'B'. Can you explain this answer?

Kiran Mehta answered
Positive economics is the branch of economics that concerns the description and explanation of economic phenomena. It focuses on facts and cause-and-effect behavioral relationships and includes the development and testing of economics theories.

Positive economics states
  • a)
    Central problems of an economy be
  • b)
    What will  
  • c)
    What is
  • d)
    What is supposed to be
Correct answer is option 'B'. Can you explain this answer?

Alok Mehta answered
Positive economics is objective and fact based, while normative economics is subjective and value based. Positive economic statements must be able to be tested and proved or disproved. Normative economic statements are opinion based, so they cannot be proved or disproved.

Which central problem explains ‘who gets more and who gets less’? 
  • a)
    Scarcity of resources
  • b)
      What to produce 
  • c)
    For whom to produce 
  • d)
    How to produce
Correct answer is option 'C'. Can you explain this answer?

This problem refers to selection of the category of people who will ultimately consume the goods, i.e. whether to produce goods for more poor and less rich or more rich and less poor. Since resources are scarce in every economy, no society can satisfy all the wants of its people. Thus, a problem of choice arises.

Which of the following is the correct expression of Marginal Rate of Transformation?
  • a)
      2Y for 1X 
  • b)
      1:2
  • c)
       2:1
  • d)
       2Y
Correct answer is option 'B'. Can you explain this answer?

Srishti Roy answered
The Marginal Rate of Transformation (MRT) is defined as the rate at which one good is exchanged for another good, while keeping the level of satisfaction of the consumer constant. It is also known as the slope of the production possibility curve.

The correct expression of Marginal Rate of Transformation is 1:2.

Explanation:

MRT is expressed as the ratio of the amount of one good that must be given up to produce an additional unit of another good. In this case, the ratio is 1:2, which means that to produce one additional unit of good X, 2 units of good Y must be given up. This implies that the opportunity cost of producing one unit of good X is 2 units of good Y.

Therefore, the correct expression for MRT is option B, which is 1:2.

  • b)
      For whom to produce
  • c)
      How to produce
  • d)

Correct answer is option 'B'. Can you explain this answer?

Anuj Choudhury answered
For whom to produce refers to selection of the category of people who will ultimately consume the goods, i.e. whether to produce goods for more poor and less rich or more rich and less poor. Since resources are scarce in every economy, no society can satisfy all the wants of its people.

As they see Opportunity cost means 
  • a)
    The money value of an opportunity in producing a good 
  • b)
    Cost of a resource used in production
  • c)
      The best alternative use of a resource
  • d)
      Next best alternative foregone
Correct answer is option 'D'. Can you explain this answer?

Jatin Sharma answered
**Explanation:**

Opportunity cost is the value of the next best alternative that is forgone when a choice is made. It is the cost of not choosing the next best alternative. In other words, it is the value of the best option that is sacrificed in order to choose a different option.

Here is a detailed explanation of why option 'D' is the correct answer:

**Next best alternative foregone:**
Opportunity cost refers to the value of the next best alternative that is foregone when a decision is made. When resources are limited, choosing to allocate them towards one option means sacrificing the benefits that could have been gained from the next best alternative. This is the essence of opportunity cost.

**Example:**
For example, suppose a person has the option to either start a business or go to college. If they choose to start a business, the opportunity cost would be the benefits that could have been gained from going to college. Conversely, if they choose to go to college, the opportunity cost would be the potential benefits of starting a business.

**Comparison with other options:**
Options A, B, and C are not the correct answers because they do not fully capture the concept of opportunity cost. While option A suggests that opportunity cost refers to the money value of an opportunity in producing a good, opportunity cost is not limited to just the money value. It also encompasses the value of the alternative uses of resources.

Option B refers to the cost of a resource used in production which is not necessarily the same as opportunity cost. While the cost of a resource is certainly a factor to consider when calculating opportunity cost, it is not the only factor. Opportunity cost takes into account the value of the next best alternative.

Option C suggests that opportunity cost is the best alternative use of a resource. While this is partly true, it does not fully capture the idea that opportunity cost is the value of the best option that is forgone when a different option is chosen.

Therefore, option 'D' is the correct answer as it best captures the concept of opportunity cost by stating that it is the next best alternative foregone.

Any allocation of resources result in
  • a)
    Consumption of goods
  • b)
    Inefficient utilization
  • c)
    Wastage of resources
  • d)

Marginal ooportunity cost is defined as the amount of one good that needs to be given up in order to increase the production of the other good by one unit. It is calculated as Units of good one sacrificed/ units of the other good obtained. PPC is concave to origin because marginal opportunity cost increase due to law of diminshing returns.

      30 tonnes of steel
  • c)
      5 tonnes of steel
  • d)
      1 ton of steel
Correct answer is option 'C'. Can you explain this answer?

Naina Sharma answered
Opportunity cost refers to a benefit that a person could have received, but gave up, to take another course of action. Stated differently, an opportunity cost represents an alternative given up when a decision is made. This cost is, therefore, most relevant for two mutually exclusive events.

Which of the statements given above is/are correct?
i. The economic problem arises due to the scarcity of resources and unlimited wants.
ii. The decision of what to produce is solely based on consumer preferences without considering resource limitations.
iii. The distribution of goods in an economy does not address the inequality of income among individuals.
iv. Alternative uses of resources require an economy to make choices about production.
  • a)
    i and iv
  • b)
    ii and iii
  • c)
    i, iii and iv
  • d)
    ii and iv
Correct answer is option 'A'. Can you explain this answer?

Statement i is correct as the economic problem stems from the conflict between limited resources and unlimited wants. Statement ii is incorrect because the decision of what to produce must consider the limitations of resources. Statement iii is incorrect because the distribution of goods does address income inequality. Statement iv is correct as alternative uses of resources necessitate choices in production. Therefore, the correct statements are i and iv.

A movement along a PPC implies
  • a)
      Redistribution of technology 
  • b)
    Redistribution of wealth
  • c)
      Reallocation of income
  • d)
      Reallocation of resources
Correct answer is option 'D'. Can you explain this answer?

Aniket Basu answered
The movement along the PPC from left to right shows that in order to produce more units of capital goods, the economy must sacrifice some amount of consumer goods.

If MOC increases, the shape of PPC will be
  • a)
    Concave
  • b)
      Inverted
  • c)
      Convex
  • d)
      Straight
Correct answer is option 'A'. Can you explain this answer?

MOC refers to the number of units of a commodity sacrificed to gain one additional unit of another commodity. In case of PPF, MOC is always increasing, i.e. more and more units of a commodity have to be sacrificed to gain an additional unit of another commodity.PPF is concave shaped because of increasing marginal opportunity costs, i.e. more and more units of one commodity are sacrificed to gain an additional unit of another commodity.

The shape of an ideal PPC is due to which of the following
  • a)
    Increasing Marginal Rate of Substitution 
  • b)
    Increasing Marginal Opportunity Cost 
  • c)
    Constant Marginal Rate of Substitution 
  • d)
    Decreasing Marginal Opportunity cost
Correct answer is option 'B'. Can you explain this answer?

Ssc Cgl answered
The ideal shape of the PPC is typically concave to the origin, reflecting increasing marginal opportunity cost. As more resources are allocated to produce one good, the opportunity cost of producing additional units of that good increases, leading to a bowed-out shape. This indicates that resources are not equally efficient in producing both goods, causing the opportunity cost to rise as production shifts.
Hence, Correct Answer - Option B

What does a point below a PPC show
  • a)
      Underutilization of resources 
  • b)
      The optimum combination of two goods 
  • c)
      Overutilization of resources 
  • d)
      Growth of resources
Correct answer is option 'A'. Can you explain this answer?

Pritam Malik answered
A point below a Production Possibility Curve (PPC) represents underutilization of resources. Let's break down the explanation in detail:

1. Understanding the PPC:
The PPC is a graphical representation of the maximum combinations of two goods that an economy can produce using all its available resources and technology efficiently. It shows the trade-off between producing different combinations of goods.

2. Shape of the PPC:
The PPC is typically downward sloping, convex to the origin, indicating the concept of increasing opportunity cost. This means that as an economy produces more of one good, it must give up increasing amounts of the other good.

3. Points on the PPC:
Points on the PPC represent the maximum possible production levels given the available resources and technology. These points indicate full utilization of resources, where the economy is efficiently allocating its resources to produce the optimal combination of goods.

4. Points below the PPC:
Points below the PPC represent inefficient utilization of resources. This occurs when an economy is not using all its available resources or not using them efficiently. At these points, the economy is producing less than its maximum potential output.

5. Reasons for underutilization:
a) Unemployment: If there is unemployment in the economy, it means that the available labor resources are not fully utilized, resulting in underutilization.
b) Idle capacity: If capital resources such as factories, machinery, or equipment are not operating at their full capacity, it leads to underutilization.
c) Inefficient resource allocation: If resources are not allocated in the most efficient way, the economy may produce less than its maximum potential.

6. Consequences of underutilization:
a) Opportunity cost: Underutilization means that the economy is not fully utilizing its resources to produce more goods and services. This leads to a missed opportunity to increase output and improve living standards.
b) Inefficiency: Underutilization indicates that resources are not being used efficiently, resulting in wasted potential and lower productivity.
c) Economic growth: Underutilization hinders economic growth as it represents a gap between the current production level and the economy's maximum potential output.

In conclusion, a point below a PPC indicates underutilization of resources, meaning that the economy is not using all its available resources efficiently to produce at its maximum potential.

Labour intensive technique would get chosen in
  • a)
       Labour surplus economy
  • b)
       Developing economies 
  • c)
      Developed economies 
  • d)
      Capital surplus economy
Correct answer is option 'A'. Can you explain this answer?

Pranavi Das answered
The labor surplus economy model has as its basic premise the inability of unskilled agricultural labor markets to clear in countries with high man/land ratios. In such situations, the marginal product of laboris likely to fall below a bargaining wage, related to the average rather than the marginal product.

The basic assumption regarding resources while drawing a PPC is
  • a)
    Resources can be put to a particular use
  • b)
    Resources depend on the kind of goods produced
  • c)
    Resources are unlimited
  • d)
    Resources are constant and given
Correct answer is option 'D'. Can you explain this answer?

Nilesh Chawla answered
Explanation:

PPC or Production Possibility Curve is a graphical representation of all possible combinations of two goods that an economy can produce with the given resources and technology.

The basic assumption regarding resources while drawing a PPC is that resources are constant and given.

This means that:

- The quantity and quality of resources available in the economy remain the same during the period under consideration.
- The technology or production techniques used to produce the goods also remain the same.
- The economy is assumed to be operating at full employment, meaning all available resources are being utilized efficiently.
- There is no external interference or changes in the economy, such as natural disasters, changes in government policies, etc.

This assumption is necessary because it simplifies the analysis of the production possibilities of an economy and helps in understanding the trade-offs involved in producing one good over the other.

If resources were not constant and given, the PPC would shift, and the analysis would become more complex.

Therefore, the assumption that resources are constant and given is a fundamental assumption while drawing a PPC.
