This paper proposes a reduced form model of dynamic duopoly in the context of heterogeneous innovations framework. Two agents invest into product and process innovations simultaneously. Every newly introduced product has its own dimension of process-improving innovations and there is a continuum...

This paper introduces the dynamical framework which combines product and process innovations. The model contributes to the theoretical literature on innovations in two ways. First, it permits for the simultaneous dynamics of both types of innovations which is rarely considered in the literature....

The paper presents a fully dynamic framework for simultaneous analysis of variety enhancing and quality improving innovations for the case of a single agent. There is a continuous stream of variety enhancing innovations and every new product from this stream has its own quality dimension which...

Current paper analyses the influence of the length of production technologies life-cycles on the relative intensity of investments of a multi-product monopolist into different types of innovations. This monopolist is developing new versions of the basic product continuously and simultaneously...

This article studies the relation between anthropogenic global warming and economic growth. It is assumed that deviations from the preindustrial average global surface temperature negatively affect aggregate output and utility. The government levies a tax on output and a tax on greenhouse gases....

In this note we theoretically investigate the question of whether the relationship between public debt and economic growth is characterized by an inverse U-shaped functional form. Starting point of our analysis is the paper by Checherita-Westphal et al. (2012) who present an endogenous growth...

This book builds on the Marx–Keynes–Schumpeter approach to understanding the evolution of capitalism. It does so by focusing on current frameworks that study macro-dynamical systems in the tradition of the Classical, the Neoclassical and the Keynesian interpretation of the working of modern...
