What Is the Crowding Out Effect?
The crowding out effect asserts that rising government spending often negatively influences private sector investment. Mainly, this occurs because as the government increases taxes or borrows more funds, it raises interest rates, making borrowing more costly for businesses and individuals. Consequently, this decreases disposable income and can discourage private investment, posing significant questions about the real impact of government involvement in economic activity.
Key Takeaways
- The crowding out effect is an economic theory that suggests increased government spending can reduce private sector investment by raising interest rates and taxes.
- Higher government borrowing can elevate real interest rates, making loans more expensive and discouraging private investment.
- The theory of crowding out contrasts with crowding in, where government spending during economic downturns can stimulate private sector activity.
- Understanding the crowding out effect is crucial as it challenges the typical assumption that government spending always boosts economic activity.

Impact of Crowding Out on Private Sector Spending
The crowding out effect is based on the supply of and demand for money. According to the theory, as the government takes revenue-raising actions, such as increasing taxes or debt security sales, the consumer and business demand for resulting higher interest rate loans decreases.
So does their desire to spend a potentially reduced amount of income. (Their desire to earn a higher rate of interest on their savings may also come into play.) Thus, the government crowds out their spending by increasing its own.
Remember, the crowding out effect opposes older economic theories, which say government spending can boost consumer and business spending during slowdowns by putting more money in their pockets.
Crowding out often occurs when a large government, like the U.S., borrows more, leading to reduced private sector spending.
The sheer scale of this type of borrowing can lead to substantial rises in the real interest rate. This can absorb the economy’s lending capacity and discourage businesses from making capital investments.
Companies often partially or fully fund capital projects through financing. The increased cost of borrowing money makes traditionally profitable projects that are funded through loans cost-prohibitive.
Important
Increased borrowing by large governments is considered to be a common cause of crowding out. The borrowing can force interest rates higher and dampen loan demand by those in the private sector.
Mechanisms of Crowding Out in the Economy
Economic Impacts of Crowding Out
Reduced corporate capital spending can partly offset benefits from government borrowing, like economic stimulus. However, this is only likely when the economy is operating at capacity. In this respect, government stimulus is theoretically more effective when the economy is below capacity.
If this is the case, however, an economic downswing may occur. This can reduce the revenues that the government collects through taxes and spur it to borrow even more money. This can theoretically lead to a cycle of more borrowing and continued crowding out.
Social Welfare Spending and Its Role in Crowding Out
Crowding out can also happen indirectly through social welfare. Higher taxes to fund welfare programs leave individuals and businesses with less discretionary income, reducing their charitable contributions.
Public spending on social welfare can reduce private donations, offsetting government efforts in the same areas.
Similarly, expanding public health insurance like Medicaid may lead private insurance customers to switch to public options. This can leave private insurers with fewer customers and a smaller risk pool, possibly resulting in higher premiums and reduced private coverage.
Government Infrastructure Projects and Crowding Out
Government-funded infrastructure projects can also crowd out private investments. These projects may discourage private firms from launching similar ventures, as they could be seen as less desirable or deemed unprofitable.
This often happens with bridges and roads, where government projects deter companies from building toll roads or similar infrastructure.
Practical Example: Crowding Out in Real-World Scenarios
Imagine a firm planning a $5 million capital project with a 3% loan interest rate and a $6 million return. The firm anticipates earning $1 million in net income (NI).
Because of the weak economy, the government announces a stimulus package to aid businesses, which raises the firm’s loan interest rate to 4%.
With the interest rate up by 33.3%, the firm’s profit model changes. Now, the project cost is expected to be $5.75 million to achieve the same $6 million in return, dropping projected earnings by 75% to $250,000.
Therefore, the company decides that it would be better off pursuing a different project or halting major projects for the time being.
Crowding Out vs. Crowding in: Understanding Competing Theories
Chartalism and Post-Keynesian economics suggest that when an economy is underperforming, government borrowing can boost demand. It does so by generating employment and thereby stimulating private spending. This process is often referred to as “crowding in.”
The crowding in theory has gained some currency among economists in recent years after it was noted that, during the Great Recession of 2007–2009, massive spending by the federal government on bonds and other securities actually had the effect of reducing interest rates.
Is Crowding Out Good or Bad?
Crowding out, if it exists, can be seen as negative because it can slow economic activity and growth. This can happen as higher taxes reduce spendable income and increased government borrowing raises borrowing costs and reduces private sector demand for loans.
Why Is Crowding Out Important to Understand?
It’s important to understand because it contradicts the well-understood theory that government spending boosts private sector spending and supports a vibrant economy.
How Does Crowding Out Affect Aggregate Demand?
According to the theory’s effect, it should reduce aggregate demand because it discourages spending and the demand for borrowing due to higher interest rates and reduced income.
The Bottom Line
The crowding out effect occurs when increased government spending leads to reduced private sector investment, often because government actions like raising taxes or selling Treasury securities cause higher interest rates and diminished disposable income. As borrowing costs rise, businesses and individuals are discouraged from spending and investing, potentially slowing economic growth. Understanding this theory is important as it contests the assumption that government spending always stimulates the economy, highlighting situations where it may dampen private financial activity.
