Q. 1 What is Gross National Product (GNP)? Give a detailed discussion on
GNP, keeping in view its measurement and resultant benefits, the items left
uncounted, its ingredients and its role in determining economic activities.
Also differentiate between GNP and NNP.
ANS.
Gross
National Product (GNP): An In-Depth Analysis
Gross National Product (GNP) is a
critical economic metric that provides a comprehensive measure of a country's
economic performance. This discussion delves into the definition, measurement,
benefits, limitations, components, and role of GNP in economic activities.
Additionally, it differentiates between GNP and Net National Product (NNP).
Definition
of Gross National Product (GNP)
Gross National Product (GNP) is the
total market value of all final goods and services produced by a nation's
residents over a specified period, typically a year. Unlike Gross Domestic
Product (GDP), which measures production within a country's borders, GNP
includes the value of goods and services produced by nationals abroad and
excludes the value of production by foreigners within the country.
Measurement
of GNP
GNP can be measured using three
approaches:
1.
Production
(Output) Approach: This method calculates GNP by
summing the value of goods and services produced by all sectors of the economy,
including agriculture, manufacturing, services, and more.
2.
Income Approach: This approach sums all incomes earned by residents of a
country, including wages, rents, interest, and profits. It includes the income
earned by nationals abroad and excludes income earned by foreigners within the
country.
3.
Expenditure
Approach: This method calculates GNP by
summing the total expenditures on final goods and services produced by the
nation's residents. The components include consumption, investment, government
spending, and net exports (exports minus imports). Additionally, it includes
net income from abroad.
Benefits
of Measuring GNP
1.
Economic
Performance Indicator: GNP serves as a comprehensive
indicator of a nation's economic performance, reflecting the total income
generated by its residents.
2.
Policy
Formulation: Policymakers use GNP data to
formulate economic policies, allocate resources, and set priorities for
economic development.
3.
International
Comparisons: GNP allows for comparisons of
economic performance between countries by providing a measure that accounts for
the economic activities of a nation's residents, regardless of location.
4.
Investment
Decisions: Investors and businesses use GNP
data to assess the economic environment, predict future growth, and make
informed investment decisions.
Items
Left Uncounted in GNP
Despite its comprehensiveness, GNP
has limitations and excludes certain items:
1.
Non-Market
Activities: GNP does not account for
non-market activities such as household labor, volunteer work, and other
informal economic activities.
2.
Environmental
Degradation: GNP does not consider the negative
externalities of production, such as environmental degradation and resource
depletion.
3.
Underground
Economy: GNP does not capture the value of
economic activities in the underground or informal economy, such as
black-market transactions and unreported income.
4.
Leisure and
Quality of Life: GNP does not measure the value of
leisure time, quality of life, and overall well-being of residents.
Ingredients
of GNP
The main components of GNP include:
1.
Consumption: The total expenditure by households on goods and services.
2.
Investment: The total expenditure on capital goods that will be used
for future production, including business investments in equipment and
structures, residential construction, and changes in inventories.
3.
Government
Spending: The total expenditure by the
government on goods and services.
4.
Net Exports: The value of a nation's exports minus its imports.
5.
Net Income from
Abroad: The difference between income
earned by nationals abroad and income earned by foreigners within the country.
Role
of GNP in Determining Economic Activities
1.
Economic Growth
Measurement: GNP is used to measure economic
growth by comparing the GNP of different periods, allowing for the assessment
of economic progress and development.
2.
Standard of
Living: GNP per capita is often used as an
indicator of the standard of living, providing insights into the average income
and economic well-being of residents.
3.
Resource
Allocation: GNP data helps in the allocation
of resources by identifying sectors contributing most to economic output and
those needing support.
4.
Economic
Planning: Governments and policymakers use
GNP data for economic planning, setting goals, and implementing strategies to
enhance economic performance.
Differentiating
Between GNP and NNP
Gross National Product (GNP) and Net
National Product (NNP) are closely related but distinct measures:
1.
Definition: While GNP measures the total market value of all final
goods and services produced by a nation's residents, NNP adjusts GNP by
subtracting depreciation (the wear and tear on capital goods).
2.
Depreciation: NNP accounts for the loss of value of capital goods over
time due to usage and obsolescence, providing a more accurate measure of a
nation's economic output by considering the sustainability of production.
3.
Economic
Sustainability: NNP is considered a better measure
of economic sustainability as it reflects the economy's capacity to maintain
production levels without depleting capital assets.
4.
Policy
Relevance: Policymakers may prefer NNP over
GNP for long-term planning and sustainability assessments, as it accounts for
the economy's ability to replace depreciated capital.
Q. 2 Discuss keynse point of view about the relationship between income
and consumption or law of consumption and its assumptions. Also discuss the
effects of objective and subjective factors on consumption function.
ANS.
Keynesian
Perspective on Income and Consumption
Introduction
John Maynard Keynes, a prominent
20th-century economist, profoundly influenced modern economic thought with his
theories on income and consumption. His ideas, primarily articulated in
"The General Theory of Employment, Interest, and Money" (1936),
challenged classical economics and introduced a new framework for understanding
economic activity. This discussion delves into Keynes's views on the relationship
between income and consumption, the law of consumption, its assumptions, and
the effects of objective and subjective factors on the consumption function.
The
Relationship Between Income and Consumption
Keynes posited that consumption is
primarily a function of current income. He introduced the concept of the
consumption function, which describes the relationship between total
consumption and gross national income. According to Keynes, consumption
increases as income rises, but not proportionately. This implies a marginal
propensity to consume (MPC) less than one.
The
Consumption Function
Keynes’s consumption function can be
expressed as:
C=a+bYC = a + bYC=a+bY
Where:
- CCC is the total consumption.
- aaa is autonomous consumption (consumption when income
is zero).
- bbb is the marginal propensity to consume (MPC).
- YYY is the disposable income.
This equation suggests that even
when disposable income (YYY) is zero, there is still some level of consumption
(aaa), reflecting basic consumption needs funded through savings or borrowing.
Law
of Consumption
The law of consumption, according to
Keynes, encompasses several key points:
1.
Absolute Income
Hypothesis: Consumption depends on absolute
income, meaning higher income leads to higher consumption, but the rate of
increase in consumption diminishes as income rises.
2.
Marginal
Propensity to Consume (MPC): The
proportion of additional income that is spent on consumption. Keynes argued
that MPC is between 0 and 1, meaning people spend part of their additional
income and save the rest.
3.
Average
Propensity to Consume (APC): The ratio of
total consumption to total income. As income increases, APC decreases because
consumption rises less proportionately than income.
Assumptions
Underlying Keynes's Theory
Keynes's theory of consumption rests
on several assumptions:
1.
Short-Run
Perspective: The theory is primarily concerned
with short-term changes in income and consumption.
2.
Stability of
Consumption Function: The consumption function remains
stable over time and is not significantly affected by factors other than
current income.
3.
Independence
from Interest Rates: Consumption decisions are largely
independent of interest rates, with income being the primary determinant.
4.
Absence of
Wealth Effects: The theory assumes that changes in
wealth have minimal impact on consumption compared to changes in income.
Objective
Factors Affecting the Consumption Function
Objective factors are external
variables that can influence the consumption function. These include:
1.
Income Levels: The most direct factor influencing consumption. Higher
disposable income typically leads to increased consumption.
2.
Wealth: An increase in wealth, such as rising property values or
stock market gains, can lead to higher consumption as individuals feel more
financially secure.
3.
Credit
Availability: Easier access to credit can boost
consumption by allowing consumers to spend beyond their current income.
4.
Interest Rates: Lower interest rates can encourage borrowing and spending,
thereby increasing consumption.
5.
Inflation: Higher inflation can erode purchasing power and reduce
consumption, while low inflation can boost consumer spending by maintaining or
increasing real income.
6.
Government
Policies: Fiscal policies, such as tax cuts
or increased public spending, can directly affect disposable income and hence
consumption.
Subjective
Factors Affecting the Consumption Function
Subjective factors are internal
variables that reflect individual or collective psychological states
influencing consumption. These include:
1.
Expectations: Consumer expectations about future income, inflation, and
economic conditions can significantly impact current consumption. Optimism
about the future can lead to higher spending, while pessimism can cause reduced
consumption and increased saving.
2.
Consumer
Confidence: A high level of consumer
confidence usually correlates with higher consumption, as individuals feel more
secure in their financial stability.
3.
Cultural
Attitudes: Cultural values and norms
regarding saving and spending can shape consumption patterns. Societies that
value thrift may exhibit lower consumption rates compared to more consumerist
cultures.
4.
Demographic
Factors: Age, family size, and other
demographic factors can influence consumption. For example, younger individuals
or larger families may have higher consumption needs.
5.
Personal
Preferences: Individual preferences and tastes
play a role in determining consumption choices. These preferences can be
influenced by lifestyle, education, and personal goals.
Effects
of Objective and Subjective Factors on the Consumption Function
The consumption function is dynamic
and influenced by a combination of objective and subjective factors.
Understanding these influences helps explain variations in consumption patterns
across different contexts.
Objective
Factors
1.
Income
Variability: Fluctuations in income due to
economic cycles (e.g., recessions or booms) can lead to changes in consumption.
For instance, during economic expansions, rising incomes can increase
consumption, while during recessions, falling incomes can decrease consumption.
2.
Wealth Effects: Changes in asset values can impact consumption through the
wealth effect. A significant increase in household wealth, such as from rising
stock prices or property values, can boost consumer confidence and lead to
higher consumption.
3.
Credit
Conditions: The availability of credit plays a
crucial role in consumer spending. Easier credit conditions can lead to
increased borrowing and higher consumption, while tighter credit conditions can
restrict spending.
4.
Interest Rates: Although Keynes emphasized income over interest rates,
modern interpretations acknowledge that lower interest rates reduce the cost of
borrowing, which can stimulate consumption, especially for big-ticket items
like homes and cars.
5.
Government
Policies: Fiscal policies, such as tax cuts
or direct transfer payments, can increase disposable income and thereby boost
consumption. Conversely, austerity measures and tax increases can reduce
disposable income and lower consumption.
Subjective
Factors
1.
Consumer
Expectations: Expectations about future economic
conditions can lead to changes in current consumption. If consumers expect
higher future income or stable economic conditions, they are more likely to
increase their current spending.
2.
Consumer
Confidence: High consumer confidence reflects
positive sentiment about the economy and personal financial situations, leading
to increased consumption. Conversely, low consumer confidence can lead to
reduced spending and higher savings.
3.
Cultural and
Social Norms: Cultural attitudes towards
spending and saving influence consumption patterns. Societies that emphasize
material success and consumption are likely to have higher consumption levels
than those that value thrift and saving.
4.
Demographic
Changes: Demographic factors, such as aging
populations, can impact consumption. Older individuals may have different consumption
patterns compared to younger people, affecting overall consumption trends.
5.
Personal
Preferences and Lifestyle Choices:
Changes in lifestyle and personal preferences can influence consumption. For
example, a shift towards health-conscious living can increase consumption of
health-related goods and services.
Q. 3 (a) Differentiate between supply and stock of money. Also
discuss ingredients of supply of money in detail.
(b) Discuss the
Fischer’s equation of exchange with a suitable example.
ANS.
Differentiating
Between Supply and Stock of Money
Introduction
Understanding the concepts of the
supply and stock of money is crucial in the field of economics. While they may
appear similar, they have distinct meanings and implications for an economy.
This discussion differentiates between the supply and stock of money and delves
into the ingredients of the money supply. It also explores Fischer’s equation
of exchange with a suitable example.
(a)
Supply vs. Stock of Money
Supply of Money: The supply of money refers to the total amount of money
available in an economy at a particular point in time. It includes various
forms of money, such as cash, coins, and balances held in checking and savings
accounts. The money supply is typically controlled by a country’s central bank
through monetary policy mechanisms like open market operations, reserve
requirements, and interest rates.
Stock of Money: The stock of money, on the other hand, represents the total
quantity of money that exists in the economy at a given time. It encompasses
all the money in circulation and held in various forms by the public and
institutions. The stock of money is a static concept, capturing a snapshot of
the money available at a specific point in time, without considering changes or
flows over time.
Ingredients
of the Supply of Money
The supply of money can be broken
down into different categories, often referred to as monetary aggregates. These
aggregates represent different components of the total money supply and are
commonly classified as M0, M1, M2, and M3, each encompassing different types of
financial assets.
1.
M0 (Monetary
Base):
o
Also known as the base money or
high-powered money, M0 includes all physical currency in circulation and
reserves held by commercial banks at the central bank.
o
Components:
§ Currency in circulation (notes and coins).
§ Bank reserves with the central bank.
2.
M1 (Narrow
Money):
o
M1 includes all of M0 plus demand
deposits (checking accounts) and other liquid assets that can be quickly
converted into cash.
o
Components:
§ Currency in circulation.
§ Demand deposits.
§ Other liquid deposits (e.g., traveler’s checks).
3.
M2 (Broad
Money):
o
M2 encompasses all of M1 and adds
savings accounts, time deposits (less than $100,000), and non-institutional
money market funds. These are less liquid than the components of M1 but still
easily convertible to cash.
o
Components:
§ All components of M1.
§ Savings accounts.
§ Time deposits (less than $100,000).
§ Non-institutional money market funds.
4.
M3:
o
M3 includes all of M2 plus large
time deposits, institutional money market funds, and other larger liquid
assets. M3 is the broadest measure of money supply.
o
Components:
§ All components of M2.
§ Large time deposits.
§ Institutional money market funds.
§ Other large liquid assets.
Factors
Affecting the Supply of Money
1.
Central Bank
Policies:
o
The central bank controls the money
supply through various tools, such as open market operations, discount rates,
and reserve requirements.
2.
Banking System:
o
Commercial banks influence the money
supply through lending activities. When banks extend loans, they create new
deposits, thereby increasing the money supply.
3.
Government
Fiscal Policies:
o
Government spending and taxation
policies can impact the money supply. For instance, deficit spending can
increase the money supply if financed through borrowing from the central bank.
4.
Public Demand
for Money:
o
The public’s preference for holding
cash versus deposits can affect the money supply. Higher demand for cash can
reduce the money supply if it leads to reduced deposits in the banking system.
(b)
Fischer’s Equation of Exchange
Introduction
Fischer’s equation of exchange is a
fundamental concept in monetarist economics, formulated by economist Irving
Fisher. It represents the relationship between money supply, velocity of money,
price levels, and the volume of transactions in an economy. This section
discusses Fischer’s equation, its components, and provides a suitable example.
Fischer’s
Equation of Exchange
Fischer’s equation of exchange is
expressed as:
MV=PTMV = PTMV=PT
Where:
- MMM is the money supply.
- VVV is the velocity of money (the average frequency
with which a unit of money is spent).
- PPP is the price level.
- TTT is the volume of transactions.
Components
of Fischer’s Equation
1.
Money Supply
(M):
o
The total amount of money available
in the economy, including cash, coins, and various types of deposits.
2.
Velocity of
Money (V):
o
The rate at which money circulates
in the economy. It reflects how often a unit of currency is used in transactions
over a period.
3.
Price Level
(P):
o
The average level of prices for
goods and services in the economy.
4.
Volume of
Transactions (T):
o
The total number of transactions or
the total output of goods and services produced in the economy.
Example
of Fischer’s Equation
Consider a simplified economy where
the following data is given for a particular year:
- Money Supply (MMM) = $500 billion
- Velocity of Money (VVV) = 4
- Price Level (PPP) = 2
Using Fischer’s equation, we can
determine the volume of transactions (TTT):
MV=PTMV = PTMV=PT
Substituting the given values:
500 billion×4=2×T500 \text{
billion} \times 4 = 2 \times T500 billion×4=2×T
2000 billion=2×T2000 \text{
billion} = 2 \times T2000 billion=2×T
T=2000 billion2T = \frac{2000
\text{ billion}}{2}T=22000 billion
T=1000 billionT = 1000 \text{
billion}T=1000 billion
This means the total volume of
transactions in this economy is $1000 billion.
Interpretation
and Implications
Fischer’s equation highlights the
relationship between the money supply and the overall economic activity. It
implies that:
1.
Constant
Velocity of Money: If the velocity of money (VVV) and
the volume of transactions (TTT) remain constant, changes in the money supply (MMM)
will directly affect the price level (PPP). An increase in the money supply, holding
other factors constant, leads to inflation.
2.
Inflation and
Deflation: If the money supply grows faster
than the volume of transactions, it results in inflation (rising price levels).
Conversely, if the money supply grows slower than the volume of transactions,
it results in deflation (falling price levels).
3.
Economic
Policy: Policymakers can use Fischer’s
equation to understand the impact of monetary policy on the economy. For
instance, increasing the money supply can stimulate economic activity if the
velocity of money and the volume of transactions are stable.
Q. 4 Discuss the historical evolution of present day modern banking
system. What is the difference between the functions of central bank and that
of commercial ones.
ANS.
Historical
Evolution of the Modern Banking System

Q. 5 Write notes on the following
(i) Ricardo’s theory of
comparative advantage.
(ii) Modern theory of
international trade.
ANS.
(i)
Ricardo's Theory of Comparative Advantage
Introduction
David Ricardo's theory of
comparative advantage is a fundamental concept in international trade, first
introduced in his book "On the Principles of Political Economy and
Taxation" published in 1817. The theory explains how and why countries benefit
from trading with each other by specializing in the production of goods where
they have a comparative advantage.
The
Concept of Comparative Advantage
Comparative advantage occurs when a
country can produce a good at a lower opportunity cost compared to another country.
It is distinct from absolute advantage, where a country can produce a good more
efficiently (using fewer resources) than another country.
Key
Principles of Ricardo's Theory
1.
Opportunity
Cost:
o
Comparative advantage is based on
the concept of opportunity cost, which is the cost of foregone alternatives
when choosing one option over another. A country has a comparative advantage in
producing a good if it has a lower opportunity cost compared to other
countries.
2.
Specialization
and Trade:
o
Ricardo argued that countries should
specialize in the production of goods for which they have a comparative
advantage and trade with other countries. This specialization allows countries
to produce more efficiently and gain from trade.
3.
Mutual Benefit:
o
Trade based on comparative advantage
benefits all participating countries. Even if one country has an absolute
advantage in producing all goods, it can still benefit from trading with
countries that have comparative advantages in different goods.
Example
of Comparative Advantage
Consider two countries, Country A
and Country B, and two goods, Wine and Cloth. The production costs are as
follows:
- Country A can produce 1 unit of Wine with 2 labor hours
and 1 unit of Cloth with 1 labor hour.
- Country B can produce 1 unit of Wine with 3 labor hours
and 1 unit of Cloth with 2 labor hours.
Country A has an absolute advantage
in producing both Wine and Cloth since it uses fewer labor hours. However, the
opportunity costs are different:
- For Country A, the opportunity cost of producing 1 unit
of Wine is 2 units of Cloth (2 labor hours for Wine vs. 1 labor hour for
Cloth).
- For Country B, the opportunity cost of producing 1 unit
of Wine is 1.5 units of Cloth (3 labor hours for Wine vs. 2 labor hours
for Cloth).
Country A has a comparative advantage
in producing Cloth (lower opportunity cost), while Country B has a comparative
advantage in producing Wine. By specializing and trading, both countries can
consume more of both goods.
Implications
of Ricardo's Theory
1.
Resource
Allocation:
o
Ricardo's theory highlights the
importance of efficient resource allocation. By specializing in goods where
they have comparative advantages, countries can use their resources more
efficiently.
2.
Gains from
Trade:
o
Comparative advantage leads to
increased overall production and consumption. Countries can achieve higher
standards of living through trade.
3.
Economic
Interdependence:
o
Ricardo's theory promotes economic
interdependence among nations. It underscores the mutual benefits of trade and
encourages international cooperation.
(ii)
Modern Theory of International Trade
Introduction
The modern theory of international
trade builds upon classical theories like Ricardo's comparative advantage and
incorporates new insights from the 20th and 21st centuries. It encompasses
various models and theories that explain the complexities of global trade,
considering factors such as economies of scale, imperfect competition, and
technological differences.
Key
Theories and Models
1.
Heckscher-Ohlin
(H-O) Model:
o
Developed by Eli Heckscher and
Bertil Ohlin, the H-O model explains international trade based on differences
in factor endowments. It states that countries will export goods that use their
abundant factors intensively and import goods that use their scarce factors
intensively.
2.
Leontief
Paradox:
o
Wassily Leontief, through empirical
analysis, found that the US (a capital-abundant country) exported
labor-intensive goods and imported capital-intensive goods, contrary to the H-O
model's predictions. This paradox led to further exploration of trade patterns.
3.
New Trade
Theory:
o
Introduced by economists like Paul
Krugman, new trade theory emphasizes the role of economies of scale and network
effects. It explains why countries with similar factor endowments engage in
trade and how trade can lead to market size expansion and increased product
variety.
4.
Intra-Industry
Trade:
o
Modern trade theory acknowledges
that countries often trade similar goods (e.g., different brands of cars)
rather than completely different goods. Intra-industry trade is driven by
product differentiation and consumer preferences for variety.
5.
Gravity Model
of Trade:
o
The gravity model predicts bilateral
trade flows based on the economic sizes (GDP) and distance between countries. It
suggests that larger economies have more trade, and geographical proximity
enhances trade relationships.
6.
Technology and
Innovation:
o
Modern theories emphasize the role
of technological advancements and innovation in shaping trade patterns.
Technological leadership can provide countries with a competitive edge in

Tariffs, quotas, and trade
agreements significantly impact international trade. Free trade agreements
(FTAs) and regional trade blocs (e.g., EU, NAFTA) facilitate trade by reducing
barriers.
3.
Political and
Economic Stability:

Political stability, economic policies,
and institutional quality affect trade flows. Stable environments attract
investment and enhance trade relationships.
4.
Logistics and
Infrastructure:

Efficient logistics, transportation
networks, and infrastructure are crucial for facilitating trade. Advances in
shipping, air freight, and digital connectivity have transformed global trade
logistics.
5.
Environmental
and Social Factors:

Sustainability concerns and social
standards are increasingly influencing trade policies and practices.
Environmental regulations and labor standards can affect trade dynamics and the
competitiveness of countries.
