Crowding-in effect

Crowding-in occurs when government spending leads to more private investment. The proposed mechanism is that government spending leads to an increase in economic growth, which encourages firms to invest due to the presence of more profitable investment opportunities. The crowding-in effect is observed when there is an increase in private investment due to increased public investment, for example, through the construction or improvement of physical infrastructures such as roads, highways, water and sanitation, ports, airports, railways, etc.[1][2][3] It is contrasted with crowding out, which occurs when government spending leads to less private investment.
History
While both crowding in and crowding out are observed empirically, there are long-standing debates over which effect tends to prevail, and under what circumstances. The theories of classical economists such as Adam Smith, J. B. Say, and Karl Marx are generally interpreted as being more consistent with crowding out.[4][5] The crowding-in effect is generally associated with the economic theories of John Maynard Keynes and the various schools of economic thought named after him. Presently, the crowding-out effect is generally associated with Neoclassical economics. The crowding-in theory has gained popularity in the aftermath of the Great Recession of 2007-2009, when public spending in the United States occurred simultaneous to a drop in interest rates.[6]
Models of the Crowding-in effect
Aschauer (1989) studied increases in the productivity of private capital resulting from the accumulation of public capital through public investment in the US. They find that nonmilitary spending, especially on core infrastructure, has a significant and positive relationship with private sector productivity. They propose that the slowdown in government spending in the early 1970s may have been an important factor in the private sector productivity decline that took place at that time.[7]
Determinants of government expenditure effects
According to neoclassical economics, in which developed economies are considered to generally operate at full employment, the crowding-in effect is more likely to occur in transitional or developing countries. In case of recession, there is unused private sector savings and production capacity (unemployed labor force, unused capital infrastructure, etc.). An increment in government expenditure significantly increases national income in developing countries due to the presence of relatively higher levels of unemployment factors of production. This increase in national income further increases the purchasing capacity and encourages the growth of private investment. At the same time, an increase in the budget deficit will have a very small influence on interest rate growth because of the high elasticity of speculative demand for money (horizontal LM curve). In transitional countries, national income is the most important factor influencing private influencing the private investment. The impact of the interest rate is much smaller.[citation needed]
Difference between crowding-out and crowding-in effect
Paul Krugman along with the majority of Neo-Keynesian economists argues that economic stimulus should be in the form of expenditure, not in the form of a tax deduction (excluding the poorest inhabitants) because the one part of tax deduction will be retained but not consumed.[citation needed] The effects of different parts of government spending (public sector financing, public investments, and transfer payments) are very different. Government expenditure changes in size and structure can have a variety of effects on economic growth.
The crowding-out effect of government spending on private investment shows itself either directly or indirectly. Indirect crowding-out takes place through an increase in interest rates and prices, but direct crowding-out occurs with the reduction of the physical resources available to the private sector. In case private expenditure doesn't decline with an increase in government expenditure, the crowding expenditure crowding out effect is zero.[8]
The crowding-in effect is more likely to occur due to the income effect of high public investment which leads to an increment in private investment. In crowding-in effect, a rise in private investment due to a rise in government investment is more effective.
Factors responsible for crowding in effect
- Recession and crowding-in – During a recession, the government tax cut increases increase aggregate demand, as people pay lower taxes they have a surplus to spend which increases demands. This rise in demand leads to more employment opportunities and crowding in businesses. Keynes's economic theories suggest a recession as the private sector has idle resources due to more savings. Therefore, government borrowing is effectively making use of these idle resources.
- High multiplier effect – The multiplier effect here refers to the relationship between government spending and total national income. The multiplier's size is proportional to the marginal propensity to consume (MPC), which is the proportion of an increase in income spent on consumption. Because of the high multiplier effect, spending rises, resulting in crowding in.
- Liquidity trap – In case of lower interest rates and fall in prices, higher government borrowing is unable to push the interest rates. The government can end a liquidity trap through an increase in government spending. It also directly reduces unemployment. In a situation of deflation, real interest rates (nominal rates -inflation) may be quite high. As public spending reduces deflation, it may help to reduce real interest rates and therefore increase private sector investment.
Limitation of crowding-in effect
Government adopts an expansionary fiscal policy stance in times of high unemployment and recession to boost economic activity. This causes an increment in aggregate demand and encourages private sector investment. But, crowding in will be limited in effect. When an economy is in recession and producing less than its potential GDP, expansionary fiscal policy is most appropriate. However, as soon as the economy returns to its long-run growth and is producing above its potential GDP, this increases interest rates which results in a reduced investment. In the case of a strong economic recovery, the rate of inflation is high. Rising inflation rates induce banks to increase interest rates. As soon as interest rates increase investment rate declines further leading to a decrease in the crowding-in effect.
