Functional Finance: A Pragmatic Approach to Economic Management
Functional Finance, a macroeconomic theory developed primarily by Abba Lerner during the mid-20th century, offers a distinctive perspective on government fiscal policy. It argues that the primary role of government financial actions should be to achieve desired macroeconomic outcomes, such as full employment and price stability, regardless of traditional budgetary concerns like balancing the budget or maintaining a certain level of public debt.
The core principle of Functional Finance is that government spending and taxation should be instruments used to influence the overall economy, not ends in themselves. Unlike traditional neoclassical economics, which often prioritizes balanced budgets and minimal government intervention, Functional Finance views these goals as secondary to achieving macroeconomic stability and societal well-being. A balanced budget, for example, is not seen as inherently virtuous but rather as a potential byproduct of pursuing more fundamental economic objectives. If a budget deficit is required to achieve full employment, then a deficit is justified. Conversely, if a surplus is needed to control inflation, then a surplus is warranted.
Lerner outlined two primary rules for Functional Finance. First, the government should maintain a reasonable level of aggregate demand. This means ensuring that there is sufficient spending in the economy to generate full employment. If private sector spending is insufficient, the government should step in to fill the gap through increased public spending or tax cuts. Second, the government should borrow money when it can’t finance desired spending with taxes and print money when it can’t borrow.
A key implication of Functional Finance is the idea that government debt is not necessarily a burden. If the debt is used to finance productive investments that stimulate economic growth and create jobs, the resulting increase in national income can more than offset the cost of servicing the debt. In this view, government debt is only problematic if it leads to inflation or crowds out private investment without generating sufficient economic benefits.
Critics of Functional Finance often express concerns about potential inflationary pressures and the potential for unsustainable levels of government debt. They argue that excessive government spending can lead to inflation, eroding the purchasing power of consumers and businesses. Furthermore, they worry that unchecked borrowing can saddle future generations with a heavy debt burden, hindering economic growth. However, proponents argue that these risks can be mitigated through careful monitoring of inflation and appropriate fiscal management, focusing on investment in productive areas of the economy that enhance long-term growth potential.
In summary, Functional Finance offers a pragmatic approach to economic management, prioritizing macroeconomic stability and full employment over traditional budgetary concerns. By viewing government spending and taxation as instruments to achieve these goals, Functional Finance provides a framework for active government intervention in the economy to promote societal well-being. While it has its critics and potential pitfalls, it remains a significant theoretical perspective in macroeconomic policy debates.
