With our book Saving and Investment in the Twenty-First Century: The Great Divergence (published as open access), we present a comprehensive theoretical explanation as well as empirical evidence for the phenomenon of low interest rates observed in the OECD countries and China and make various...

The original Keynesian paradigm differs from the Neoclassical Synthesis and even more so from the New-Keynesian approach. In this paper, a modern framework for the original Keynesian paradigm is presented. It will highlight the key elements of the paradigm. A model is developed to determine...

We analyze the microfoundations for Keynesian aggregate demand effects by considering the link between aggregate demand and firm production decisions under monopolistic competition. Macroeconomic equilibrium is characterized in a simple graphical framework that facilitates comparison of several...

This paper explores zero lower bound (ZLB) economics. The ZLB is widely invoked to explain stagnation and it fits with the long tradition that argues Keynesian economics is a special case based on nominal rigidities. The ZLB represents the newest rigidity. Contrary to ZLB economics, not only...

This paper asks whether the post-Keynesian or New Keynesian paradigm provides a more realistic description of the effects of fiscal policy on output and consumption. I establish some macro and microeconomic stylized facts on fiscal multipliers and marginal propensities to consume based on the...

This paper explores the Marxian genetic root of the multiplier in order to clarify its foundations and validity conditions. Though the analysis is restricted to the first two volumes of Capital and the early contributions by Kalecki in the 1930s, we argue that we can draw from these works...
