Covid-19 and the euthanasia of interest rates: A critical assessment of central bank policy in our times

Thomas Mayer; Gunther Schnabl

Dezember 2021

Abstract

We compare the New Keynesian and Austrian explanations for low interest rates in the light of the Corona crisis. From a New Keynesian perspective low interest rates are the result of structural changes in the society and the economy as well as the cyclical downswing triggered by the Corona pandemic. In contrast, from the perspective of Austrian economic theory, interest rates have been pushed down on trend by central banks for a long time to stimulate growth, with the global financial crisis of 2007/08 and the Corona crisis of 2020 acting as powerful accelerators of the euthanasia of interest. New Keynesian theory would suggest that interest rates can be adjusted upward again when conditions change, without creating economic and financial disturbances. Against this, Austrian theory finds that central banks have backed themselves into a corner by creating persistent low-interest expectations.

Niedrigzinspolitik und Sparkultur in Japan: Implikationen für die Wirtschaftspolitik

Gunther Schnabl; Tim Sepp

August 2021

Abstract

Das Papier untersucht die Veränderung der Sparkultur in Japan während mehr als 30 Jahren Niedrig-, Null- und Negativzinspolitik basierend auf einer Analyse der Allokationsfunktion von Zinsen und der Transformationsfunktion der Banken bei der Kreditvergabe. Es wird gezeigt, wie durch die anhaltend lockere Geldpolitik der Bank von Japan die Sparkultur in Japan grundlegend von einer hohen Haushaltssparquote zu einer sehr niedrigen Haushaltssparquote verändert wurde. Es werden aufbauend auf der theoretischen Literatur zu Sparmotiven Kanäle identifiziert, die das Haushalts- und Unternehmenssparen maßgeblich verändert und damit die Wachstumskräfte des Landes anhaltend geschwächt haben.

Reasons for the Demise of Interest: Savings Glut and Secular Stagnation or Central Bank Policy?

Thomas Mayer; Gunther Schnabl

April 2021

Abstract

In this paper we compare the Keynesian, neoclassical and Austrian explanations for low interest rates and sluggish growth. From a Keynesian and neoclassical perspective low interest rates are attributed to ageing societies, which save more for the future (global savings glut). Low growth is linked to slowing population growth and a declining marginal efficiency of investment as well as to declining fixed capital investment due to digitalization (secular stagnation). In contrast, from the perspective of Austrian business cycle theory, interest rates were step by step decreased by central banks to stimulate growth. This paralyzed investment and growth in the long term. We show that the ability of banks to extend credit ex nihilo and the need of time to produce capital invalidates the IS identity assumed in the Keynesian theory to hold permanently. Furthermore, we find no empirical evidence for the global savings glut and secular stagnation hypotheses. Instead, low growth can be explained by the emergence of quasi “soft budget constraints” as a result of low interest rates, which reduce the incentive for banks and enterprises to strive for efficiency.

China’s Overinvestment and International Trade Conflicts

Gunther Schnabl

September 2019

Abstract

For a long time, China's impressive growth performance has been driven by investment and high productivity gains. Based on a discussion of possible overcapacities and overinvestment in China, this paper investigates the sustainability of China's investment and export‐driven growth model. Since the turn of the millennium, buoyant capital inflows and low interest rates have been at the root of overinvestment and misallocation of capital, which necessitated export subsidies to clear markets. The overinvestment boom is argued to have ended around 2014. Since then, the overcapacities have weakened China's bargaining position in the US–Chinese trade conflict and have tempted Chinese authorities to postpone the restructuring of the Chinese economy by providing low‐interest credit. The gradual reemergence of quasi‐soft budget constraints is seen to undermine China's long‐term growth potential.
