Abstract
This study attempts to identify uncertainty in the long-term rate of interest based on the controversial interest-rate theories of Keynes and Kalecki. While Keynes stated that the future of the rate of interest is uncertain because it is numerically incalculable, Kalecki was convinced that it could be predicted. The theories are empirically tested using GARCH-in-mean (MGARCH) models without and with restrictions assigned to six globally leading financial markets. The obtained results support Keynes’s case: the long-term rate of interest is a non-ergodic financial phenomenon. Analyses of the relation between the interest rate and macroeconomic variables without interest uncertainty are thus seriously incomplete.
期刊介绍：
The Review of Keynesian Economics (ROKE) is dedicated to the promotion of research in Keynesian economics. Not only does that include Keynesian ideas about macroeconomic theory and policy, it also extends to microeconomic and meso-economic analysis and relevant empirical and historical research. The journal provides a forum for developing and disseminating Keynesian ideas, and intends to encourage critical exchange with other macroeconomic paradigms. The journal is dedicated to the development of Keynesian theory and policy. In our view, Keynesian theory should hold a similar place in economics to that held by the theory of evolution in biology. Many individual economists still work within the Keynesian paradigm, but intellectual success demands institutional support that can leverage those individual efforts. The journal offers such support by providing a forum for developing and sharing Keynesian ideas. Not only does that include ideas about macroeconomic theory and policy, it also extends to microeconomic and meso-economic analysis and relevant empirical and historical research. We see a bright future for the Keynesian approach to macroeconomics and invite the economics profession to join us by subscribing to the journal and submitting manuscripts.
