The Role of Quantitative Easing in Economic Recovery: A Keynesian Perspective

The debate surrounding the efficacy of quantitative easing (QE) by the U.S. Federal Reserve has often been intertwined with the principles of Keynesian economics. In this article, we will explore how QE can be considered a validation of Keynesian thought during periods of economic downturn.

Understanding the Liquidity Trap and Keynesian Theory

John Maynard Keynes, the prominent economist of the early 20th century, recognized the limitations of monetary policy during times of extreme economic contraction. According to Keynes, monetary policy—such as increasing the money supply to stimulate economic activity—becomes ineffective in a “liquidity trap”. In such a situation, further attempts to increase money supply do not lead to increased lending or investment, as interest rates are already at historically low levels. This fundamental critique forms the basis of Keynesian economics and its emphasis on the need for fiscal policy measures to address economic downturns.

The QE Era: A Test Case for Keynesian Theory

The period between 2008 and the present has seen a significant implementation of QE by the Federal Reserve. While the intent behind QE was to increase the monetary base, thereby injecting liquidity into the banking system, the results have been somewhat inconclusive. Let’s examine the data and analysis behind these events.

The chart illustrates the sharp increase in the monetary base, which, according to traditional monetary theory, would lead to an increase in excess reserves, bank lending, and ultimately aggregate demand. However, in reality, the increase in reserves has been significant but their effect on lending and economic activity has been minimal. This situation aligns perfectly with Keynes' prediction of a liquidity trap, where the supply of money does not translate into increased production or employment.

Keynesian Response: Fiscal Policy

A true Keynesian would argue that during a liquidity trap, fiscal policy—such as government spending and tax cuts—is essential to stimulate economic activity. The recent tax cut implemented under Donald Trump, although not necessarily part of a Keynesian policy framework, did bring about a reduction in the unemployment rate to a very low 3.6%. This illustrates how fiscal policies can have significant and measurable impacts on economic recovery.

Limitations and Criticisms of QE

While QE has proven to be a useful tool for maintaining financial stability and preventing deflation, it has been criticized for its limitations. Some economists argue that QE does not directly address the underlying issues of a liquidity trap, as it focuses solely on monetary policy instead of enabling increased government spending. Critics note that many companies benefit from the low interest rates by leveraging more debt to fund mergers, acquisitions, and capital expenditures, but this does not necessarily lead to job creation for the broader population.

From industry datasets (chart data not shown), we can observe that the majority of new loans during the QE era were directed towards large corporations and mergers and acquisitions. While these activities can lead to short-term economic gains, they often result in reduced employment and increased financial leverage, which may not translate into sustainable job creation or economic recovery.

Conclusion

Quantitative easing can be seen as a validation of Keynesian economics during periods of extreme liquidity traps, where monetary policy alone is insufficient to stimulate the economy. However, a more comprehensive approach involving fiscal policy is necessary to achieve robust and sustainable economic recovery. The effectiveness of monetary measures like QE is limited by the extent to which they can influence real economic variables such as employment and wages.
