Fiscal Policy

Economics

Roles and Objectives of Fiscal Policy

Learning Outcome Statement:

describe roles and objectives of fiscal policy as well as arguments as to whether the size of a national debt relative to GDP matters

Summary:

Fiscal policy involves government spending and tax adjustments to influence the economy, including aggregate demand, income distribution, and resource allocation. It plays a crucial role in economic stabilization during different economic cycles, influencing employment and output through expansionary or contractionary measures. The effectiveness and impact of fiscal policy can vary significantly based on economic conditions and prevailing economic theories, such as those proposed by Keynesians and Monetarists. Additionally, the size of national debt relative to GDP is a critical aspect, with arguments both for and against its significance in economic stability and growth.

Key Concepts:

Fiscal Policy and Aggregate Demand

Fiscal policy can influence aggregate demand through various tax cuts or increases in public spending, aiming to boost economic activity by increasing disposable income and consumer demand.

Automatic Stabilizers

These are built-in government mechanisms, such as progressive taxes and unemployment benefits, that automatically adjust to economic changes without the need for new legislative measures, helping to stabilize economic fluctuations.

Discretionary Fiscal Policies

These involve deliberate changes in government spending or taxation policies intended to influence economic activity, differing from automatic stabilizers as they require active government intervention.

Government Deficits and Debt

Government deficits occur when spending exceeds revenue, financed by borrowing. Accumulated deficits contribute to national debt, which can influence economic stability and investor confidence depending on its size relative to GDP.

Arguments on National Debt Size

There are debates on whether the size of national debt relative to GDP is concerning. Arguments against concern include internal ownership of debt and investment in productive capital, while arguments for concern include potential higher taxes, inflation risks, and crowding out private investment.

Fiscal Policy Tools

Learning Outcome Statement:

describe tools of fiscal policy, including their advantages and disadvantages

Summary:

Fiscal policy tools are mechanisms through which governments influence economic activity. These tools include government spending on goods, services, and infrastructure, and the imposition of taxes. Each tool has specific advantages, such as immediate impacts on economic behavior from indirect taxes, and disadvantages, such as the slow implementation of capital spending plans. The fiscal multiplier concept illustrates how changes in government spending and taxation impact aggregate demand and output.

Key Concepts:

Government Spending

Government spending includes transfer payments, current spending on recurring services, and capital expenditures. This spending influences economic growth, income distribution, and the provision of public goods.

Taxes

Taxes are divided into direct taxes (on income, wealth, and profits) and indirect taxes (on consumption). They serve to finance government expenditures and redistribute income and wealth.

Fiscal Multiplier

The fiscal multiplier measures the effect of changes in fiscal policy on aggregate demand. It quantifies how government spending and taxation indirectly affect spending through consumption and saving behaviors.

Balanced Budget Multiplier

This concept explains that if government spending increases by the same amount as taxes, aggregate output still rises due to the marginal propensity to consume being less than one, leading to a multiplier effect.

Formulas:

Fiscal Multiplier

11−c(1−t)\frac{1}{1 - c(1 - t)}

This formula calculates the fiscal multiplier, showing the impact of an increase in government spending or a change in tax rate on the economy's output.

Variables:
cc:
marginal propensity to consume
tt:
tax rate
Units: unitless

Disposable Income

YD=Y−NT=(1−t)YYD = Y - NT = (1 - t)Y

This formula represents how disposable income is affected by net taxes, which are assumed to be proportional to national income.

Variables:
YDYD:
disposable income
YY:
national income or output
NTNT:
net taxes
tt:
net tax rate
Units: currency

Fiscal Policy Implementation

Learning Outcome Statement:

explain the implementation of fiscal policy and difficulties of implementation as well as whether a fiscal policy is expansionary or contractionary

Summary:

The implementation of fiscal policy involves understanding the fiscal stance through the budget deficit and structural deficit, and recognizing the challenges in executing fiscal policy effectively due to information lags, economic uncertainties, and macroeconomic conditions. The fiscal stance can be misleading if only the nominal deficit is considered, without accounting for the economic cycle and inflation. Difficulties in fiscal policy execution include recognition, action, and impact lags, as well as the unpredictability of economic responses to policy measures.

Key Concepts:

Government Debt and Fiscal Deficit

Government debt is the total outstanding IOUs issued by the government, and the fiscal deficit is the amount by which government expenditures exceed tax revenues in a given period, contributing to the increase in total debt.

Ricardian Equivalence

This concept suggests that when a government finances its spending through debt rather than taxation, individuals anticipate future taxes to repay the debt and thus save more, neutralizing the impact of the government's spending on the economy.

Structural Budget Deficit

This is the deficit that would exist if the economy were at full employment, providing a clearer measure of the fiscal stance by excluding temporary fluctuations due to the economic cycle.

Automatic Stabilizers

These are mechanisms built into the fiscal system, such as progressive taxes and unemployment benefits, that automatically adjust to changes in economic conditions without explicit government intervention, helping to stabilize the economy.

Discretionary Fiscal Adjustments

These are deliberate policy changes made by the government to influence economic activity, such as adjusting tax rates or altering government spending, aimed at stabilizing the economy.

Policy Lags

These include recognition lag (time to recognize an economic problem), action lag (time to implement a policy decision), and impact lag (time for the policy to affect the economy), all of which hinder the effectiveness of fiscal policy.

Crowding Out

This occurs when government borrowing leads to higher interest rates or absorbs available savings, potentially reducing private investment in the economy.
