This paper analyzes the theoretical and quantitative implications of optimal capital taxation in the neoclassical growth model with aggregate shocks and incomplete markets. The model features a representative-agent economy with proportional taxes on labor and capital. I first consider the case...

In order to understand the sources of profits or monetary profits of capitalists and firms, the author examines the phrase of Marx: 'Die Gesamtklasse der Kapitalisten kann nichts aus der Zirkulation herausziehen, was nicht vorher hineingeworfen war.' (The class of capitalists cannot extract from...

In this paper, we set up a model of economic growth which deals with Keynesian unemployment, from non-Walrasian/Keynesian perspectives, investigate the possibility of persistent “growth cycles” generated and analyze the effects of flexibility of (real) wages on the long-run economic...

Robert Solow has criticized our 2006 Journal of Economic Perspectives essay describing "Modern Macroeconomics in Practice." Solow eloquently voices the commonly heard complaint that too much macroeconomic work today starts with a model with a single type of agent. We argue that modern...

The problem of the economic effects of the dynamics of the oil price is versatile. The review of the literature on the matter helps outlining the main aspects of manifesting the effects and identifying the areas, which are less studied and which developing would be a contribution to the...

We implement a new approach for the identification of "news shocks" about future technology. In a VAR featuring a measure of aggregate technology and several forward-looking variables, we identify the news shock as the shock orthogonal to technology innovations that best explains future...

This paper presents a Keynesian critique of Steve Keen's treatment of the aggregate demand–credit–endogenous money nexus. It argues his analytic intuition is correct but is developed in the wrong direction. Keen's fundamental relation describing determination of AD in an endogenous...

Bruun and Heyn-Johnsen (2009) state the paradox that economics has failed to provide a satisfactory explanation of how monetary profits are generated, even though the generation of a physical surplus is an established aspect of non-neoclassical economics. They emphasise that our ability to...

How and why do financial conditions matter for real outcomes? The ‘workhorse model of money and liquidity’ of Kiyotaki and Moore (2008) shows how--with full employment maintained by flexible prices--shifting credit constraints can affect investment and future aggregate supply. We show that,...
