Chapter 5 Government Budget And The Economy



The government budget is presented as a powerful instrument of fiscal policy, which the government uses to achieve its three main objectives: allocation of resources (providing public goods), redistribution of income, and stabilization of the economy.

The chapter breaks down the budget into its key components: revenue and capital receipts, and revenue and capital expenditures. The balance between these components determines if the budget is in surplus, balanced, or in deficit. The various measures of deficit—Revenue, Fiscal, and Primary—are explained, with the Fiscal Deficit being the most important as it represents the government's total borrowing requirement.

Crucially, changes in government spending (G) and taxes (T) have a multiplier effect on national income. An increase in government spending has a larger impact on income than an equivalent tax cut, a feature that makes fiscal policy a key tool for managing aggregate demand and stabilizing the economy against booms and recessions.

Government Budget — Meaning and Its Components

In a mixed economy, where both the private sector and the government play significant and complementary roles, the government's economic functions are primarily executed through its budget. The government budget is a comprehensive financial statement that outlines the government's estimated receipts (income) and estimated expenditures for a forthcoming financial year.

In India, this is a constitutional mandate under Article 112, which requires the government to present an 'Annual Financial Statement' to the Parliament for each financial year, running from 1 April to 31 March. The budget is not merely an accounting exercise; it is the government's primary tool for implementing its economic policies and a powerful statement of its national priorities.

The budget is structured into two main accounts to distinguish between transactions that have a short-term impact and those that affect the government's long-term financial position:

  1. Revenue Account (or Revenue Budget): This account deals with receipts and expenditures that are of a current or recurring nature. These transactions relate only to the current financial year and do not create any future assets or liabilities for the government.
  2. Capital Account (or Capital Budget): This account deals with receipts and expenditures that concern the government's assets and liabilities. These are non-recurring transactions that have a long-term impact on the government's financial standing.

Objectives of the Government Budget

The government uses its budget as the principal instrument to intervene in the economy and enhance the welfare of its people. The budget is designed to achieve several key objectives.

1. Allocation Function: Reallocation of Resources

The government budget plays a crucial role in allocating resources in the economy, particularly for the provision of goods and services that the free market mechanism fails to provide efficiently. These are known as public goods.

Public goods are fundamentally different from private goods (like food, clothes, or cars) due to two distinct characteristics:

This non-excludability leads to the 'free-rider problem': individuals have an incentive to consume the good without contributing to its cost. Since private firms cannot profitably charge for public goods due to this problem, they have no incentive to produce them. The government must therefore step in to provide these goods, financing them through its budget (i.e., through taxation). It's important to distinguish between public provision (where the government finances the good) and public production (where the government itself produces the good).

2. Redistribution Function: Reducing Income and Wealth Inequalities

The market mechanism, left to itself, often results in a distribution of income and wealth that may be considered socially or ethically unfair. The government uses the budget to influence this distribution and reduce inequality. This redistribution function is carried out through both the revenue and expenditure sides of the budget:

By taxing the rich and spending on the welfare of the poor, the government works to achieve a more equitable distribution of disposable income.

3. Stabilisation Function: Maintaining Economic Stability

Capitalist economies are prone to natural fluctuations in aggregate economic activity, known as business cycles (periods of boom and recession). The government uses its budget to moderate these fluctuations and maintain economic stability. This is known as the stabilisation function, implemented through counter-cyclical fiscal policy.



Classification of the Budget Components

The government budget is systematically organized into two main parts: receipts and expenditures. Each of these is further classified into a revenue account and a capital account, based on whether the transaction affects the government's long-term assets and liabilities.

A chart showing the components of the Government Budget, branching into Revenue and Capital Budgets, which are further divided into their respective receipts and expenditures.

Classification of Budget Receipts

Budget receipts refer to the estimated money that the government receives from all sources during a financial year. They are classified into two main categories.

1. Revenue Receipts

Revenue receipts are those inflows of money that neither create a corresponding liability for the government nor lead to a reduction in its assets. These are regular, recurring, and non-redeemable sources of income for the government. They are further divided into:

2. Capital Receipts

Capital receipts are those inflows of money that either create a liability for the government or cause a reduction in its financial assets. These receipts are generally non-recurring in nature.


Classification of Budget Expenditure

Budget expenditure refers to the estimated spending of the government during a financial year. It is classified into two main categories.

1. Revenue Expenditure

Revenue expenditure is the expenditure that neither creates any physical or financial assets for the government nor causes a reduction in its liabilities. It is short-term in nature and is incurred for the normal functioning of government departments, the provision of various services, and to meet recurring expenses.

The main items of revenue expenditure include:

2. Capital Expenditure

Capital expenditure is the expenditure that either creates a physical or financial asset for the government or causes a reduction in its financial liabilities. This type of expenditure is long-term and developmental in nature. It adds to the capital stock of the economy and enhances its future productive capacity.

The main items of capital expenditure include:



Balanced, Surplus, and Deficit Budget

Based on the relationship between the government's total estimated expenditure and its total estimated receipts, the budget can be classified into three types:


Measures of Government Deficit

When a government's spending is more than its revenue, it incurs a budget deficit. There are several ways to measure this deficit, and each measure provides different and important insights into the government's fiscal health and its implications for the economy.

1. Revenue Deficit

The revenue deficit focuses exclusively on the revenue account of the budget. It is the excess of the government's revenue expenditure over its revenue receipts.

Revenue Deficit = Revenue Expenditure – Revenue Receipts

Implications of a Revenue Deficit:

2. Fiscal Deficit

The fiscal deficit is the most comprehensive measure of a government's fiscal imbalance. It is defined as the difference between the government's total expenditure and its total receipts, excluding borrowings.

Gross Fiscal Deficit = Total Expenditure – (Revenue Receipts + Non-debt Creating Capital Receipts)

(Non-debt creating capital receipts are items like the recovery of loans and disinvestment proceeds).

Implications of a Fiscal Deficit:

3. Primary Deficit

The fiscal deficit includes the amount of money the government needs to borrow to cover its interest payments on previously accumulated debt. The primary deficit is a measure that isolates the deficit of the current year's fiscal operations, excluding these past obligations. It is calculated by subtracting net interest liabilities from the gross fiscal deficit.

Gross Primary Deficit = Gross Fiscal Deficit – Net Interest Liabilities

Implications of the Primary Deficit:



Fiscal Policy and its Impact

What is Fiscal Policy?

Fiscal policy is the primary tool through which a government influences the macroeconomy. It refers to the deliberate use of government's spending and revenue-raising activities—namely, government expenditure (G) and taxes (T)—to achieve its macroeconomic objectives. As conceptualized by Keynes, the main purpose of fiscal policy is to stabilize the level of output, income, and employment by managing the level of aggregate demand in the economy.

Fiscal policy can be of two types, depending on the state of the economy:


The Government Expenditure and Tax Multipliers

Just like private investment, changes in government spending and taxes have a magnified or multiplier effect on the equilibrium level of national income. This is because they alter the circular flow of income, setting off a chain reaction of spending and income generation.

Changes in Government Expenditure and the Government Expenditure Multiplier

An increase in government purchases (G) represents a direct, autonomous injection of spending into the economy. This initial expenditure immediately becomes income for households and firms. This new income is then partly consumed, creating a second round of income, and so on. This leads to a final increase in equilibrium income that is much larger than the initial increase in G.

The government expenditure multiplier is the ratio of the change in equilibrium income to the change in government spending. Its formula is identical to the investment multiplier:

$ \text{Government Expenditure Multiplier} = \frac{\Delta Y}{\Delta G} = \frac{1}{1 - MPC} = \frac{1}{MPS} $

This is because a change in G, like a change in I, is a direct change in autonomous aggregate demand.

Changes in Taxes and the Tax Multiplier

The effect of a change in taxes is more indirect. A tax cut ($\Delta T$ is negative) does not directly increase aggregate demand. Instead, it first increases households' disposable income ($Y_d = Y - T$). Households will then spend only a fraction of this additional disposable income, as determined by their MPC. The initial increase in consumption, and thus the initial injection into the circular flow, is only $MPC \times (-\Delta T)$.

Because the initial impact on spending is smaller, the tax multiplier is weaker than the government expenditure multiplier. The formula for the tax multiplier is:

$ \text{Tax Multiplier} = \frac{\Delta Y}{\Delta T} = \frac{-MPC}{1 - MPC} = \frac{-MPC}{MPS} $

The tax multiplier is negative (because a tax increase reduces income, and a tax cut increases it) and is always smaller in absolute value than the government expenditure multiplier.

The Balanced Budget Multiplier

This concept addresses the question: What happens to national income if the government increases its spending (G) and finances it by an equal increase in taxes (T), such that the budget remains balanced ($\Delta G = \Delta T$)?

Intuitively, one might think the net effect is zero. However, because the government expenditure multiplier is stronger than the tax multiplier, there is a net positive effect on income. The balanced budget multiplier is always equal to 1.

This means that if government spending and taxes are both increased by ₹100 crore, the equilibrium national income will also rise by exactly ₹100 crore. The initial injection of ₹100 crore from G is more powerful than the initial withdrawal of spending caused by the ₹100 crore tax hike (which is only $MPC \times 100$).


Automatic Stabilisers and Proportional Taxes

Some elements of the fiscal system are designed to automatically cushion the economy from the shocks of the business cycle without any new, discretionary policy action by the government. These are known as automatic stabilisers.

Case of Proportional Taxes

A key example is a proportional income tax system, where the government collects a fixed fraction, $t$, of income in the form of taxes (i.e., $T = tY$). This system has an inherent stabilizing property:

A proportional tax system makes the economy less volatile by reducing the size of the multiplier. The new multiplier in an economy with a proportional tax is given by: $ k = \frac{1}{1 - c(1-t)} $, which is smaller than the multiplier with lump-sum taxes ($1/(1-c)$).

Other automatic stabilisers include welfare transfers like unemployment benefits, which automatically increase during a recession (supporting demand) and decrease during a boom.



Government Debt

When a government runs a budget deficit, its total expenditure exceeds its non-borrowed receipts. This shortfall must be financed. While governments can, in theory, print money to cover the gap, the more common method is to borrow. Continuous borrowing over many years leads to the accumulation of government debt, which is the total outstanding amount that the government owes to its lenders.

It is crucial to distinguish between deficits and debt. A budget deficit is a flow concept, measured as the shortfall per year. Government debt is a stock concept, representing the total accumulated borrowings at a specific point in time. Each year's deficit adds to the total stock of debt.


Is Government Debt a Burden? Perspectives on the Issue

The question of whether government debt is a burden on the economy, particularly on future generations, is a central and contentious topic in macroeconomics. There are several competing perspectives on this issue.

Arguments that Debt IS a Burden

Counterarguments (Why Debt May NOT be a Burden)


Other Perspectives on Deficits and Debt


Deficit Reduction

Concern over the long-term consequences of high debt often leads to calls for deficit reduction. A government can reduce its deficit through two main channels:

  1. Increasing Revenue:
    • Taxation: The government can increase tax revenue by raising tax rates or widening the tax base. In India, there has been an effort to increase reliance on direct taxes (like income and corporate tax), which are generally progressive, rather than on indirect taxes, which can be regressive.
    • Non-Tax Revenue: The government can also raise receipts through the sale of shares in Public Sector Undertakings (PSUs), a process known as disinvestment.
  2. Reducing Expenditure:

    This is often the main focus of deficit reduction efforts. It can be achieved by:

    • Making government activities and programmes more efficient through better planning and administration to reduce wastage. For example, replacing inefficient subsidies with direct cash transfers.
    • Changing the scope of government by withdrawing from certain economic activities and leaving them to the private sector.

    However, cutting government expenditure is challenging. A large portion of it is "committed expenditure" (like interest payments, salaries, and pensions) that is difficult to reduce. Furthermore, cutting back on crucial spending in areas like education, health, and poverty alleviation can have adverse long-term effects on economic growth and social welfare.



Fiscal Responsibility and Budget Management Act, 2003 (FRBMA)

Rationale for the FRBMA

In a multi-party parliamentary system like India's, there is often a tendency for governments to be influenced by electoral concerns, which can lead to populist expenditure policies and a lack of long-term fiscal discipline. To address this, it was argued that a legislative provision, binding on all present and future governments, was needed to keep deficits under control.

The enactment of the Fiscal Responsibility and Budget Management Act (FRBMA) in August 2003 marked a turning point in India's fiscal reforms. The Act provided an institutional framework to compel the government to pursue a prudent fiscal policy.

The core objectives of the FRBMA are to:


Main Features of the Act

  1. Deficit Reduction Targets: The Act originally mandated the central government to reduce the fiscal deficit to not more than 3% of GDP and to completely eliminate the revenue deficit by March 31, 2009 (this deadline has since been revised multiple times).
  2. Annual Reduction Path: It required a minimum annual reduction in the fiscal deficit by 0.3% of GDP and in the revenue deficit by 0.5% of GDP.
  3. Escape Clause: The specified targets could be exceeded only on exceptional grounds, such as a threat to national security or a natural calamity.
  4. Restriction on Borrowing from RBI: The Act prohibited the central government from borrowing directly from the Reserve Bank of India (RBI), except through 'ways and means advances' to meet temporary cash flow mismatches. This was a crucial step to stop the automatic monetization of deficits.
  5. Prohibition on Primary Market Subscription: It mandated that from 2006-07 onwards, the RBI must not subscribe to the primary issues of central government securities. This forces the government to raise its borrowings from the open market.
  6. Enhanced Transparency: The Act mandated measures to ensure greater transparency in fiscal operations.
  7. Mandatory Parliamentary Statements: It requires the central government to lay three key policy statements before both Houses of Parliament along with the Annual Budget:
    • The Medium-term Fiscal Policy Statement: Sets three-year rolling targets for fiscal indicators.
    • The Fiscal Policy Strategy Statement: Outlines the government's fiscal priorities.
    • The Macroeconomic Framework Statement: Assesses the prospects of the economy.

Evolution and Review

While the FRBMA was seen as a landmark legislation, the rigid targets have been subject to review and revision over the years, especially in the wake of economic shocks like the 2008 global financial crisis and the COVID-19 pandemic. An FRBM Review Committee was later set up to revamp the framework to incorporate the changing economic scenario in India and to provide a more flexible and realistic path for fiscal consolidation. Despite these changes, the core principle of a rule-based fiscal policy remains a key feature of India's macroeconomic management.



Goods and Services Tax (GST)

Concept: One Nation, One Tax, One Market

The Goods and Services Tax (GST), implemented on July 1, 2017, is the biggest and most significant indirect tax reform in India since independence. It is a single, comprehensive tax levied on the supply of goods and services, right from the manufacturer to the final consumer.

GST is a destination-based consumption tax, which means the tax revenue accrues to the state where the goods or services are finally consumed, rather than the state where they are produced.


Problems with the Pre-GST Tax Regime

The previous indirect tax system was highly fragmented and complex. It suffered from a major flaw known as the cascading of taxes or "tax on tax."

Previously, taxes (like Central Excise Duty and State VAT) were levied at each stage of production on the total value of the commodity, which included taxes paid at the previous stages. The facility to claim credit for taxes paid on inputs (Input Tax Credit) was very limited. This led to a cascading effect, which increased the cost of production and the final price paid by the consumer.


How GST Works: The Value Added Principle and ITC

GST is designed to eliminate the cascading effect. It is effectively a tax on the value addition at each stage of the supply chain. This is achieved through the mechanism of Input Tax Credit (ITC).

Example: If a retailer buys a good for ₹100 + ₹18 GST (total ₹118) and sells it for ₹150, their output tax liability would be 18% of ₹150 = ₹27. However, they can claim an ITC of ₹18 that they already paid. So, their net tax payment to the government is only ₹27 - ₹18 = ₹9, which is 18% of the value they added (₹50).


Taxes Subsumed by GST

GST has replaced a large number of Central and State indirect taxes.

NCERT Questions Solution



Question 1. Explain why public goods must be provided by the government.

Answer:

Public goods, such as national defence, roads, and public parks, must be provided by the government because the private sector, guided by the market mechanism, has no incentive to supply them. This failure of the market arises from two unique characteristics of public goods:


1. Non-Rivalrous Consumption:

The consumption of a public good by one person does not reduce its availability to others. For example, one person benefiting from a street light does not prevent another person from also benefiting. This means the marginal cost of providing the good to an additional user is zero, making it inefficient for a private company to charge for it.


2. Non-Excludable:

It is impossible or prohibitively expensive to exclude non-payers from enjoying the benefits of a public good. For instance, it is not feasible to prevent a citizen from benefiting from national defence, even if they do not pay for it. This leads to the 'free-rider problem', where individuals will wait for others to pay for the good and then consume it for free.


Because of the free-rider problem, a private firm cannot generate revenue by producing public goods. As there is no profit motive, the private sector will not provide them. Therefore, the government must step in, provide these goods for the collective welfare of society, and finance them through compulsory payments like taxes.

Question 2. Distinguish between revenue expenditure and capital expenditure.

Answer:

The distinction between revenue expenditure and capital expenditure is based on whether the spending creates assets or reduces liabilities for the government.

Revenue Expenditure:

This is expenditure that neither creates any assets nor reduces any liability for the government. It is short-term, recurring in nature, and is incurred for the normal functioning of government departments and the provision of various services. Examples include salaries, pensions, subsidies, and interest payments on government debt.


Capital Expenditure:

This is expenditure that either creates a physical or financial asset or causes a reduction in a liability for the government. It is long-term, developmental, and non-recurring in nature. Examples include the construction of roads and hospitals, purchase of machinery, investment in shares, and repayment of the principal amount of loans.

Question 3. ‘The fiscal deficit gives the borrowing requirement of the government’. Elucidate.

Answer:

The statement is correct. The fiscal deficit is the primary indicator of the government's borrowing requirement.


Elucidation:

Fiscal deficit is defined as the excess of the government's total expenditure over its total receipts, excluding borrowings. The formula is:

Fiscal Deficit = Total Expenditure – (Revenue Receipts + Non-debt Creating Capital Receipts)

This formula essentially calculates the gap between the government's total spending and its total income from non-borrowed sources. Since this gap represents the amount of expenditure that is not covered by its own receipts, the only way to finance this shortfall is through borrowing.

Therefore, the calculated value of the fiscal deficit is precisely equal to the total amount of money the government needs to borrow from all sources, including the domestic market, the Reserve Bank of India, and foreign countries.

Question 4. Give the relationship between the revenue deficit and the fiscal deficit.

Answer:

The revenue deficit is a component of the fiscal deficit. The relationship can be derived as follows:

Fiscal Deficit = Total Expenditure – (Revenue Receipts + Non-debt creating Capital Receipts)


We know that Total Expenditure = Revenue Expenditure + Capital Expenditure.

Substituting this into the fiscal deficit formula:

Fiscal Deficit = (Revenue Expenditure + Capital Expenditure) – Revenue Receipts – Non-debt creating Capital Receipts


Rearranging the terms:

Fiscal Deficit = (Revenue Expenditure – Revenue Receipts) + (Capital Expenditure – Non-debt creating Capital Receipts)


Since (Revenue Expenditure – Revenue Receipts) is the Revenue Deficit, the final relationship is:

Fiscal Deficit = Revenue Deficit + (Capital Expenditure – Non-debt creating Capital Receipts)

This shows that a part of the fiscal deficit is the revenue deficit. A high revenue deficit component indicates that a large portion of the government's borrowing is being used to finance its consumption expenditure rather than for productive investment.

Question 5. Suppose that for a particular economy, investment is equal to 200, government purchases are 150, net taxes (that is lump-sum taxes minus transfers) is 100 and consumption is given by $C = 100 + 0.75Y_D$ where $Y_D$ is disposable income.

(a) What is the level of equilibrium income?

(b) Calculate the value of the government expenditure multiplier and the tax multiplier.

(c) If government expenditure increases by 200, find the change in equilibrium income.

Answer:

Given:

  • I = 200
  • G = 150
  • Net Taxes (T) = 100
  • Consumption (C) = 100 + 0.75$Y_D$
  • MPC (c) = 0.75

(a) What is the level of equilibrium income?

Disposable income ($Y_D$) = Y - T = Y - 100.

So, the consumption function is $C = 100 + 0.75(Y - 100)$.

The equilibrium condition is Y = C + I + G.

$Y = [100 + 0.75(Y - 100)] + 200 + 150$

$Y = 100 + 0.75Y - 75 + 350$

$Y = 375 + 0.75Y$

$Y - 0.75Y = 375$

$0.25Y = 375$

$Y = 375 / 0.25 = 1500$

The equilibrium level of income is 1500.


(b) Calculate the value of the government expenditure multiplier and the tax multiplier.

Government Expenditure Multiplier = $\frac{1}{1-c} = \frac{1}{1 - 0.75} = \frac{1}{0.25} = 4$.

Tax Multiplier = $\frac{-c}{1-c} = \frac{-0.75}{1 - 0.75} = \frac{-0.75}{0.25} = -3$.

The multipliers are 4 and -3 respectively.


(c) If government expenditure increases by 200, find the change in equilibrium income.

Change in Income ($\Delta Y$) = Government Expenditure Multiplier $\times$ Change in G ($\Delta G$)

$\Delta Y = 4 \times 200 = 800$

The change in equilibrium income is an increase of 800.

Question 6. Consider an economy described by the following functions: $C = 20 + 0.80Y_D$, $I = 30$, $G = 50$, $TR = 100$ (where $Y_D$ is disposable income and there are no taxes).

(a) Find the equilibrium level of income and the autonomous expenditure multiplier in the model.

(b) If government expenditure increases by 30, what is the impact on equilibrium income?

(c) If a lump-sum tax of 30 is added to pay for the increase in government purchases, how will equilibrium income change?

Answer:

Given:

  • C = 20 + 0.80$Y_D$
  • I = 30
  • G = 50
  • Transfers (TR) = 100
  • Taxes (T) = 0
  • MPC (c) = 0.80

(a) Find the equilibrium level of income and the autonomous expenditure multiplier.

Disposable Income ($Y_D$) = Y - T + TR = Y - 0 + 100 = Y + 100.

Consumption function: C = 20 + 0.80(Y + 100) = 20 + 0.8Y + 80 = 100 + 0.8Y.

Equilibrium condition: Y = C + I + G

$Y = (100 + 0.8Y) + 30 + 50$

$Y = 180 + 0.8Y$

$0.2Y = 180$

$Y = 180 / 0.2 = 900$

The equilibrium level of income is 900.

Autonomous Expenditure Multiplier = $\frac{1}{1-c} = \frac{1}{1 - 0.8} = \frac{1}{0.2} = 5$.


(b) If government expenditure increases by 30, what is the impact on equilibrium income?

Impact ($\Delta Y$) = Multiplier $\times$ $\Delta G = 5 \times 30 = 150$.

The equilibrium income will increase by 150.


(c) If a lump-sum tax of 30 is added to pay for the increase in government purchases, how will equilibrium income change?

This is a balanced budget change ($\Delta G = 30$ and $\Delta T = 30$). The balanced budget multiplier is always 1.

Change in Income ($\Delta Y$) = Balanced Budget Multiplier $\times$ $\Delta G = 1 \times 30 = 30$.

The equilibrium income will increase by 30.

Question 7. In the above question, calculate the effect on output of a 10 per cent increase in transfers, and a 10 per cent increase in lump-sum taxes. Compare the effects of the two.

Answer:

Initial values from Q6: c = 0.8, TR = 100. There were no initial taxes.

Effect of a 10% increase in transfers:

Change in Transfers ($\Delta TR$) = 10% of 100 = 10.

Transfer Multiplier = $\frac{c}{1-c} = \frac{0.8}{1 - 0.8} = \frac{0.8}{0.2} = 4$.

Change in Output ($\Delta Y$) = Transfer Multiplier $\times$ $\Delta TR = 4 \times 10 = 40$.

A 10% increase in transfers will increase output by 40.


Effect of a 10% increase in lump-sum taxes:

Since initial taxes were 0, a 10% increase is not well-defined. Let's assume it means a new lump-sum tax of 10 (equal to the increase in transfers).

Change in Taxes ($\Delta T$) = 10.

Tax Multiplier = $\frac{-c}{1-c} = \frac{-0.8}{1 - 0.8} = \frac{-0.8}{0.2} = -4$.

Change in Output ($\Delta Y$) = Tax Multiplier $\times$ $\Delta T = -4 \times 10 = -40$.

A 10% increase in taxes will decrease output by 40.


Comparison:

An equal increase in transfers and lump-sum taxes has an equal and opposite effect on the equilibrium output. The increase in transfers raises income, while the increase in taxes lowers it by the same absolute amount.

Question 8. We suppose that $C = 70 + 0.70Y D$, $I = 90$, $G = 100$, $T = 0.10Y$

(a) Find the equilibrium income.

(b) What are tax revenues at equilibrium income? Does the government have a balanced budget?

Answer:

Given:

  • C = 70 + 0.70$Y_D$
  • I = 90
  • G = 100
  • Tax Rate (t) = 0.10, so T = 0.10Y

(a) Find the equilibrium income.

Disposable Income ($Y_D$) = Y - T = Y - 0.10Y = 0.90Y.

Consumption function: C = 70 + 0.70(0.90Y) = 70 + 0.63Y.

Equilibrium condition: Y = C + I + G

$Y = (70 + 0.63Y) + 90 + 100$

$Y = 260 + 0.63Y$

$Y - 0.63Y = 260$

$0.37Y = 260$

$Y = 260 / 0.37 \approx 702.7$

The equilibrium income is approximately 702.7.


(b) What are tax revenues at equilibrium income? Does the government have a balanced budget?

Tax Revenue (T) = 0.10 $\times$ Y = 0.10 $\times$ 702.7 = 70.27.

Government Expenditure (G) = 100.

Budget Balance = Tax Revenue - Government Expenditure = 70.27 - 100 = -29.73.

The tax revenues are 70.27. Since expenditure (100) is greater than revenue (70.27), the government does not have a balanced budget; it has a budget deficit.

Question 9. Suppose marginal propensity to consume is 0.75 and there is a 20 per cent proportional income tax. Find the change in equilibrium income for the following

(a) Government purchases increase by 20

(b) Transfers decrease by 20.

Answer:

Given:

  • Marginal Propensity to Consume (c) = 0.75
  • Proportional Income Tax Rate (t) = 20% = 0.20

First, we need to calculate the value of the multiplier for an economy with proportional taxes. The formula is:

$ \text{Multiplier (k)} = \frac{1}{1 - c(1-t)} $

$ k = \frac{1}{1 - 0.75(1 - 0.20)} = \frac{1}{1 - 0.75(0.80)} = \frac{1}{1 - 0.60} = \frac{1}{0.40} = 2.5 $


(a) Government purchases increase by 20:

The change in equilibrium income ($\Delta Y$) is calculated by multiplying the change in government purchases ($\Delta G$) by the multiplier.

$\Delta Y = k \times \Delta G$

$\Delta Y = 2.5 \times 20 = 50$

The equilibrium income will increase by 50.


(b) Transfers decrease by 20:

A change in transfers ($\Delta TR$) first affects consumption by $c \times \Delta TR$. This initial change in spending then gets magnified by the multiplier.

Initial change in spending = $c \times \Delta TR = 0.75 \times (-20) = -15$.

Total change in equilibrium income ($\Delta Y$) = Multiplier $\times$ Initial change in spending

$\Delta Y = 2.5 \times (-15) = -37.5$

The equilibrium income will decrease by 37.5.

Question 10. Explain why the tax multiplier is smaller in absolute value than the government expenditure multiplier.

Answer:

The tax multiplier is smaller in absolute value than the government expenditure multiplier because a change in government spending has a more direct impact on aggregate demand than a change in taxes.


Government Expenditure Multiplier: An increase in government expenditure (G) is a direct injection of spending into the economy. If G increases by Rs 100, aggregate demand increases by the full Rs 100 in the first round. This entire amount then enters the multiplier process.


Tax Multiplier: A decrease in taxes (T) does not directly increase spending. It first increases households' disposable income. Households then spend only a fraction of this extra income, as determined by their Marginal Propensity to Consume (MPC). For example, if taxes are cut by Rs 100 and the MPC is 0.8, the initial increase in consumption spending is only Rs 80 ($0.8 \times 100$). Only this smaller amount of Rs 80 enters the multiplier process.


Since the initial injection into the circular flow of income is smaller for a tax cut than for an equal increase in government spending, the final magnified effect on equilibrium income is also smaller.

Question 11. Explain the relation between government deficit and government debt.

Answer:

The relationship between government deficit and government debt is that of a flow to a stock.


Government Deficit: This is a flow concept. It represents the shortfall of the government's total receipts compared to its total expenditure over a specific period, usually a financial year. To cover this shortfall, the government must borrow.


Government Debt: This is a stock concept. It represents the total accumulated amount of borrowings by the government over many years that has not yet been repaid. It is the total outstanding liability of the government at a particular point in time.


The relation is that the deficit in any given year adds to the total stock of debt. For example, if the government had an existing debt of Rs 1000 crore and runs a deficit of Rs 200 crore this year, its total debt at the end of the year will be Rs 1200 crore. Thus, deficits are the annual additions to the total government debt.

Question 12. Does public debt impose a burden? Explain.

Answer:

Whether public debt imposes a burden is a complex issue with several perspectives.

Arguments that Debt IS a Burden:

  • Burden on Future Generations: It is argued that by borrowing today, the government shifts the burden of repayment to future generations. Future taxpayers will have to pay higher taxes to repay the debt and interest, which reduces their disposable income and consumption.
  • Crowding Out Private Investment: When the government borrows heavily, it competes for the limited pool of savings in the economy. This can drive up interest rates, making it more expensive for private firms to borrow and invest. This "crowding out" of private investment can lead to a smaller capital stock and slower economic growth in the future.

Counterarguments that Debt may NOT be a Burden:

  • Internal Debt ("We owe it to ourselves"): If the debt is held domestically, the interest payments are simply a transfer from one group (taxpayers) to another (bondholders) within the same country. There is no net loss of purchasing power for the nation as a whole. This argument does not apply to external debt owed to foreigners.
  • Productive Use of Borrowed Funds: If the government uses the borrowed money for productive public investments like building infrastructure, schools, and hospitals, it can increase the economy's future productive capacity. If the return on these investments is higher than the interest rate on the debt, future generations may be better off.
  • Ricardian Equivalence: This theory suggests that forward-looking consumers understand that government borrowing today implies higher taxes in the future. They will increase their savings now to prepare for this, offsetting the government's borrowing. In this view, national savings do not fall, and investment is not crowded out.

Question 13. Are fiscal deficits inflationary?

Answer:

Fiscal deficits are not always inflationary. The inflationary impact of a fiscal deficit depends on the state of the economy.


When deficits CAN be inflationary:

If the economy is already operating at or near its full employment level, it means there are very few unutilised resources. In this situation, if the government runs a deficit (by increasing spending or cutting taxes), it will increase aggregate demand. Since firms cannot easily increase production, this excess demand will lead to a rise in the general price level, causing inflation. This is especially true if the deficit is financed by the central bank printing new money.


When deficits may NOT be inflationary:

If the economy is in a recession and there are significant unutilised resources (like high unemployment and idle factories), a fiscal deficit that increases aggregate demand will prompt firms to increase their output and hire more workers. In this Keynesian scenario, the deficit leads to an increase in real output and employment rather than an increase in prices.

Question 14. Discuss the issue of deficit reduction.

Answer:

Deficit reduction involves policies aimed at lowering the government's budget deficit. This can be achieved through two primary channels:

1. Increasing Government Revenue:

  • Taxation: The government can raise tax revenue by increasing existing tax rates or by widening the tax base to include more people and activities. In India, the focus has been on improving compliance and increasing reliance on direct taxes.
  • Non-Tax Revenue: Revenue can be increased through measures like the sale of shares in Public Sector Undertakings (PSUs), a process known as disinvestment.

2. Reducing Government Expenditure:

This is often the main focus of deficit reduction efforts. It can involve:

  • Improving Efficiency: Making government programmes and administration more efficient to reduce wastage. For instance, replacing poorly targeted subsidies with direct cash transfers.
  • Changing the Scope of Government: The government can withdraw from certain areas and allow the private sector to play a larger role.

Challenges in Deficit Reduction:

Reducing expenditure is difficult because a large part of it is committed (e.g., interest payments, salaries, pensions). Furthermore, cutting spending in crucial areas like health, education, and poverty alleviation can have severe negative consequences for social welfare and long-term economic growth.

Question 15. What do you understand by G.S.T? How good is the system of G.S.T as compared to the old tax system? State its categories.

Answer:

What is G.S.T?

The Goods and Services Tax (GST) is a single, comprehensive, destination-based indirect tax levied on the supply of goods and services across India. It replaced a multitude of Central and State taxes, creating the principle of 'One Nation, One Tax, One Market'.


How is G.S.T better than the old tax system?

The GST system is a significant improvement over the old tax system primarily because it eliminates the cascading effect of taxes (or 'tax on tax').

  • In the old system, taxes were levied at each stage on the total value of the product, which included taxes paid at previous stages.
  • Under GST, tax is levied only on the value addition at each stage. This is achieved through a seamless system of Input Tax Credit (ITC), where a producer can claim credit for the taxes already paid on their inputs. This reduces the cost of production and the final price for the consumer.

Other benefits include a simplified tax structure, increased transparency, and the creation of a common national market.


Categories of G.S.T:

GST is structured with a dual model to accommodate the fiscal requirements of both the Centre and the States:

  • CGST (Central GST): Levied by the Central Government on intra-state supplies of goods and services.
  • SGST (State GST): Levied by the State Governments on intra-state supplies of goods and services.
  • UTGST (Union Territory GST): Levied by Union Territory Governments on intra-state supplies.
  • IGST (Integrated GST): Levied by the Central Government on inter-state supplies of goods and services.
