The paper presents an infinite horizon model of innovation and diffusion incorporating features from recent advances in evolutionary economics. A stochastic variant is explored which posits that technological knowledge is costly to obtain, requiring resource expenditure. There are heterogeneous...

This paper studies intertemporal investment strategies under inflation risk by extending the intertemporal framework of Merton (1973) to include a stochastic price index. The stochastic price index gives rise to a two-tier evaluation system: agents maximize their utility of consumption in real...

We consider a Keynes-Goodwin model of effective demand and the distributive cycle where workers purchase goods and houses with marginal propensity significantly larger than one. They therefore need credit, supplied from asset holders, and have to pay interest on their outstanding debt. In this...

In this paper we consider the applied structural model of diequilibrium growth that we introduced in a previous paper. In particular we express the model in terms of intensive form variables which turn out to be governed by a set of 39D dynamic equations. We consider the model from the...

The causes of the present crisis are largely to be found in the unregulated development of new financial products and in the over-expansion of the financial sector, in particular the shadow banking sector, which emerged precisely to avoid regulation. These changes led to lower risk perception,...

In this paper we test whether German public debt has been sustainable by resorting to a test proposed by Bohn (1998). We apply non-parametric and semi-parametric regressions with time depending coefficients. This test shows that the mean of the coefficient relevant for sustainability has been...

This article introduces a stable cross-dual adjustment process for Sraffa-von Neumann models. Excluding free goods, but not process extinction, from consideration, it proves furthermore the global asymptotic stability of a simple modification of this classical adjustment process. The...

By contrasting endogenous growth models with facts, one is frequently confronted with the prediction that levels of economic variables, such as R&D expenditures, imply lasting effects on the growth rate of an economy. As stylized facts show, the research intensity in most advanced countries has...
