What Is Crowding Out?
Crowding out is a phenomenon in macroeconomics where increased government borrowing and spending reduce, or "crowd out," private investment and consumption. This typically occurs when a government increases its demand for loanable funds in financial markets, often to finance a budget deficit. The heightened demand for these funds can drive up interest rates, making it more expensive for businesses and individuals to borrow money for their own investments or spending24, 25. This competition for funds thus shifts resources from the private sector to the public sector.
History and Origin
The concept of crowding out has roots extending back to the 18th century, though the term itself gained prominence much later. Discussions regarding the potential for public sector expansion to negatively impact economic performance have resurfaced during major economic crises throughout history. The modern debate surrounding crowding out intensified particularly in the 1970s, often contrasting with Keynesian economic theories that emphasized the stimulative effects of government spending. Economists from different schools of thought, including Classical and Monetarist, have debated the extent and significance of crowding out23.
Key Takeaways
- Crowding out describes the reduction in private sector economic activity due to increased government involvement or spending.
- It commonly arises when government borrowing to finance deficits increases demand for funds, potentially leading to higher interest rates.
- Higher interest rates can discourage private borrowing for consumption and investment, shifting resources from private to public use.
- The extent of crowding out can depend on the state of the economy; it is generally more pronounced when the economy is near full employment21, 22.
- Critics of the theory often highlight scenarios where government spending may not lead to crowding out, particularly during recessions or when resources are underutilized20.
Interpreting Crowding Out
The interpretation of crowding out hinges on understanding its impact on the allocation of an economy's resources. When crowding out occurs, it implies a reallocation of capital and other resources from the private sector, which typically allocates capital based on market efficiency and potential returns, to the public sector19. This shift can affect long-term economic growth and the overall composition of output. For instance, if government borrowing pushes up interest rates, fewer private projects—such as building new factories or expanding businesses—may be undertaken because the cost of capital becomes prohibitive. Th18is can slow down the accumulation of private capital, which is a key driver of productivity and future output. Th17e degree to which private activity is displaced is a central point of analysis when evaluating the effectiveness of fiscal policy.
Hypothetical Example
Consider a hypothetical economy, "Innovatia," initially with stable interest rates at 4%. Businesses in Innovatia plan to invest $500 billion in new technologies and expansion. The government of Innovatia then announces a massive new infrastructure spending program, requiring it to borrow an additional $200 billion from the capital markets.
This sudden surge in government borrowing significantly increases the overall demand for loanable funds. According to principles of supply and demand, with a fixed supply of available savings in the short term, this increased demand pushes up the price of borrowing—the interest rate. Let's say interest rates rise from 4% to 6%. At this higher rate, many private businesses find their planned projects are no longer profitable. For example, a tech company that expected a 5% return on a new research facility may now cancel the project because the 6% borrowing cost exceeds its projected return. As a result, private investment in Innovatia falls from $500 billion to $400 billion. In this scenario, $100 billion of private investment has been "crowded out" by the government's increased borrowing.
Practical Applications
Crowding out is a critical consideration for policymakers when implementing fiscal policy, especially when managing the national debt. For instance, when governments issue large amounts of bonds to finance expenditures, this can affect bond prices and yields, which in turn influence broader interest rates in the economy. High16er interest rates can reduce private investment in areas like housing and business expansion, potentially slowing down economic growth over the long term.
The14, 15 phenomenon is also debated in the context of public goods provision. If the government provides services that could otherwise be supplied by the private sector, it might prevent private businesses from entering those markets, thus crowding them out. For example, a 2012 economic letter from the Federal Reserve Bank of San Francisco discussed how government fiscal policy could impact interest rates..
13Limitations and Criticisms
Despite its theoretical coherence, the existence and extent of crowding out in practice are subjects of ongoing debate among economists. A primary criticism is that the theory often assumes an economy is operating at or near full employment, where resources are already fully utilized. In a12 recessionary environment, where there is slack capacity and underutilized resources, increased government spending may instead "crowd in" private investment by stimulating aggregate demand and confidence, rather than crowding it out. Duri10, 11ng the period following the 2008 financial crisis, for example, some countries experienced persistently low interest rates despite high budget deficits.
Fur9thermore, the impact of government borrowing on interest rates can be offset by other factors, such as an increase in the supply of credit due to higher aggregate income, which some empirical evidence suggests. Some7, 8 economists also argue that the theory sometimes oversimplifies how financial markets and household expectations react to government borrowing. For example, the New York Times has featured opinions questioning the severity of deficit concerns and the crowding out argument, particularly in an environment of low interest rates. The 6relationship between monetary policy and fiscal policy also complicates the analysis, as central bank actions can influence interest rates and thus mitigate or exacerbate crowding out.
Crowding Out vs. Multiplier Effect
Crowding out and the multiplier effect represent two contrasting perspectives on the economic impact of government spending. The multiplier effect suggests that an initial increase in government spending leads to a proportionally larger increase in overall economic activity, as the money spent by the government circulates through the economy and stimulates further private consumption and private investment. It posits that government intervention can generate a net positive stimulus, particularly during economic downturns when resources are idle.
In contrast, crowding out argues that government spending, particularly if financed by debt, displaces private sector activity. Instead of stimulating additional private spending, it redirects resources that would otherwise have been used by businesses and individuals. While the multiplier effect focuses on the amplifying impact of government spending, crowding out emphasizes the displacement effect, suggesting that the benefits of public spending might be partially or fully offset by a reduction in private sector activity. The extent to which one effect outweighs the other often depends on prevailing economic conditions and the financing methods of government expenditure.
FAQs
What causes crowding out?
Crowding out is typically caused by increased government borrowing to finance deficits, which raises the demand for funds in financial markets. This can lead to higher interest rates, making it more expensive for the private sector to borrow and invest, thus reducing their economic activity.
###4, 5 Is crowding out always a negative outcome?
Not necessarily. While crowding out generally implies a reduction in private investment, its overall impact depends on economic conditions and the nature of government spending. If the economy has significant idle resources (e.g., during a recession), government spending might "crowd in" private activity by boosting overall demand. Also3, if the government invests in highly productive public goods or infrastructure, the long-term benefits to society might outweigh the short-term displacement of private spending.
###2 How can crowding out be avoided or minimized?
Crowding out can be minimized if government spending is financed by means other than borrowing from the private sector, such as by printing money (though this carries inflation risks) or by increasing taxes in a way that doesn't significantly deter private spending. It can also be less severe in an economy with excess capacity, where there are ample loanable funds and idle resources, reducing the upward pressure on interest rates.1
