8.4 Crowding Out Effect
4 min read•august 15, 2024
Fiscal policy can stimulate the economy, but it comes with a catch. When the government borrows to fund spending, it can drive up . This makes it harder for businesses and consumers to borrow, potentially reducing private investment and spending.
The effect varies depending on economic conditions. During recessions, it's usually less pronounced. But when the economy is near full capacity, can have a bigger impact on interest rates and private investment.

- Crowding out refers to the phenomenon where increased government borrowing and spending leads to a reduction in private sector investment and spending
- Fiscal policy involves the government's use of taxation and spending to influence economic activity
- , such as increased government spending or tax cuts, is often used to stimulate the economy during a recession (2008 financial crisis, COVID-19 pandemic)
- When the government engages in expansionary fiscal policy, it typically needs to borrow money by issuing bonds to finance the increased spending or tax cuts
- As the government borrows more money, it competes with private sector borrowers for available funds in the loanable funds market
Factors affecting crowding out
- The magnitude of the crowding out effect depends on various factors
- Size of the fiscal stimulus
- Sensitivity of private investment to interest rates
- State of the economy
- In a recession with high unemployment and low interest rates, the crowding out effect may be relatively small
- Excess capacity in the economy
- Private investment is less sensitive to interest rates
- In an economy operating near full capacity, the crowding out effect may be more significant
- Higher interest rates have a greater impact on private investment decisions
- Empirical studies have found mixed evidence on the extent of crowding out
- Some suggest that the effect is relatively small
- Others indicate a more substantial impact
Government borrowing and investment
Impact on interest rates
- The increased demand for loanable funds by the government puts upward pressure on interest rates
- Higher interest rates make borrowing more expensive for private sector businesses and consumers
- Leads to a reduction in private investment and spending (new factories, equipment purchases)
- The higher interest rates also attract foreign capital inflows
- Can lead to an appreciation of the domestic currency
- Makes exports less competitive and imports cheaper
Effect on private investment
- The reduced private investment due to higher interest rates can partially offset the stimulative effects of the expansionary fiscal policy
- Private investment is a key component of and economic growth
- Includes business investment in capital goods (machinery, buildings) and residential investment (housing construction)
- Crowding out of private investment can limit the of government spending
- Multiplier effect refers to the increase in aggregate demand resulting from an initial increase in spending
Crowding out and fiscal stimulus
Effectiveness of fiscal policy
- The extent to which crowding out can reduce the effectiveness of fiscal stimulus depends on the specific circumstances
- In a deep recession with significant slack in the economy, crowding out may be less pronounced
- Government spending can help stimulate demand and boost economic activity
- Example: Infrastructure investment during the Great Depression (New Deal programs)
- In an economy near full employment, crowding out may be more significant
- Additional government spending may lead to higher inflation and interest rates
- Can crowd out private investment and consumption
Ricardian equivalence
- Ricardian equivalence is a related concept that suggests that fiscal stimulus may be ineffective due to changes in consumer behavior
- According to this theory, consumers anticipate future tax increases to pay for current government borrowing
- As a result, they increase their savings and reduce their consumption
- Ricardian equivalence implies that the stimulative effect of fiscal policy may be offset by reduced private spending
- Empirical evidence on Ricardian equivalence is mixed and depends on factors such as consumer expectations and credit constraints
Monetary policy vs crowding out
Role of monetary policy
- Monetary policy, conducted by the central bank, can be used to counteract the crowding out effect of expansionary fiscal policy
- If the central bank engages in accommodative monetary policy, it can help offset the upward pressure on interest rates caused by government borrowing
- Lowering interest rates
- Purchasing government bonds (quantitative easing)
- By keeping interest rates low, accommodative monetary policy can encourage private investment and spending
- Reduces the extent of crowding out
- The coordination of fiscal and monetary policy can be challenging
- Different objectives and time horizons
Transmission mechanism and effectiveness
- The effectiveness of monetary policy in mitigating crowding out depends on the transmission mechanism of monetary policy
- How changes in interest rates and money supply affect the real economy
- The responsiveness of the economy to changes in interest rates is a key factor
- Interest rate sensitivity of investment and consumption
- Monetary policy may be less effective in stimulating the economy during a severe recession or liquidity trap
- Zero lower bound on nominal interest rates
- Example: Japan's experience with prolonged low interest rates and deflation
- The interaction between fiscal and monetary policy is complex and requires careful consideration by policymakers
- Balancing short-term stimulus with long-term sustainability
- Avoiding unintended consequences and distortions in the economy
Key Terms to Review (18)
AD-AS Model: The AD-AS model, or Aggregate Demand-Aggregate Supply model, is a framework used to analyze the overall economy by depicting the relationship between total spending (aggregate demand) and total production (aggregate supply). This model helps explain price levels, output, and economic fluctuations, making it essential for understanding various macroeconomic concepts, such as shifts in demand and supply, business cycles, and the impact of fiscal and monetary policies.
Aggregate Demand: Aggregate demand represents the total demand for all goods and services in an economy at a given overall price level and in a given time period. It is a critical component in understanding how various factors, including consumption, investment, and government spending, interact to influence economic activity and overall demand in the economy.
Classical Economics: Classical economics is a school of thought that emerged in the late 18th and early 19th centuries, emphasizing free markets, the self-regulating nature of economies, and the idea that supply creates its own demand. This perspective is critical for understanding how economies operate over time, particularly regarding production, labor, and the long-term growth of national income.
Crowding In: Crowding in refers to the phenomenon where increased government spending leads to an increase in private sector investment. This occurs when public investment enhances the economic environment, prompting businesses to expand and invest due to improved infrastructure, services, or overall economic conditions. Crowding in contrasts with crowding out, where government spending displaces private investment instead.
Crowding Out: Crowding out refers to the phenomenon where increased government spending leads to a reduction in private sector investment, often due to rising interest rates. When the government borrows more to fund its expenditures, it can push interest rates up, making it more expensive for businesses and individuals to borrow money, ultimately reducing private investment and consumption.
Economic Output: Economic output refers to the total value of all goods and services produced within an economy over a specific period, often measured through indicators like Gross Domestic Product (GDP). It reflects the productive capacity of an economy and indicates how well resources are being utilized to create wealth. Higher economic output typically correlates with increased employment, higher standards of living, and improved overall economic health.
Expansionary fiscal policy: Expansionary fiscal policy is a government strategy used to stimulate economic growth by increasing public spending or reducing taxes. This approach aims to boost aggregate demand, encourage investment, and create jobs, particularly during periods of economic downturn or high unemployment.
Financial Markets: Financial markets are platforms or systems that facilitate the buying and selling of financial assets, such as stocks, bonds, and derivatives. They play a crucial role in the economy by enabling capital to flow from savers to borrowers, thereby supporting investment and economic growth. In addition, they help determine the prices of these assets through supply and demand dynamics.
Government borrowing: Government borrowing refers to the process by which a government raises funds to cover its budget deficits by issuing debt, typically in the form of bonds or loans. This practice allows governments to finance public spending without immediately raising taxes, but it can also have significant implications for the economy, including affecting interest rates and private investment levels.
Interest Rates: Interest rates are the cost of borrowing money or the return on savings, typically expressed as a percentage of the principal amount over a specified period. They play a crucial role in economic decisions, influencing consumption, investment, and the overall performance of the economy.
Investment spending: Investment spending refers to the expenditure on capital goods that will be used to produce goods and services in the future. This type of spending is crucial for economic growth as it leads to increased production capacity and innovation. It plays a significant role in the economy by affecting aggregate demand and influencing shifts in both the aggregate demand and supply curves, as well as having implications for interest rates and government policy.
IS-LM Model: The IS-LM model represents the interaction between the goods market and the money market in an economy, showing how interest rates and output are determined simultaneously. It helps explain how fiscal and monetary policy can influence overall economic activity, connecting essential concepts like aggregate demand and supply shifts, crowding out effects, and the phases of the business cycle.
John Maynard Keynes: John Maynard Keynes was a British economist whose ideas fundamentally changed the theory and practice of macroeconomics, particularly during the 20th century. He is best known for advocating that government intervention is necessary to stabilize economic cycles and to promote full employment and economic growth.
Keynesian Economics: Keynesian economics is an economic theory that emphasizes the role of government intervention in stabilizing the economy through fiscal and monetary policies. It suggests that during periods of economic downturns, increased government spending and lower taxes can help stimulate demand, which in turn can lead to economic recovery. This approach contrasts with classical economics, advocating for active policy responses to mitigate recessions and support full employment.
Long-term growth: Long-term growth refers to the sustained increase in a country's output of goods and services over an extended period, typically measured by the growth rate of real GDP. This growth is influenced by various factors, including technological advancements, increases in capital stock, and improvements in labor productivity. Understanding long-term growth is crucial for analyzing economic performance and policy implications, especially in relation to investment strategies and government fiscal policies.
Milton Friedman: Milton Friedman was an influential American economist known for his strong belief in the importance of free markets and limited government intervention in the economy. His ideas significantly shaped macroeconomic thought, particularly around consumption, inflation, and monetary policy, advocating for the role of money supply in influencing economic activity.
Multiplier effect: The multiplier effect refers to the phenomenon where an initial increase in spending leads to a larger overall increase in national income and economic activity. This concept illustrates how fiscal and monetary policies can amplify changes in economic activity, emphasizing the interconnectedness of various economic agents and sectors.
Resource Allocation: Resource allocation refers to the process of distributing available resources among various uses or projects to achieve desired outcomes. This concept is crucial in understanding how economies manage their limited resources effectively, ensuring that they are directed towards the most efficient and productive avenues. It plays a significant role in determining how investments, public spending, and production are structured within an economy.
