In this paper we analyze the importance of recycling in the strive for sustainable development. In contrast to former approaches we emphasize the role of the waste stock as a source of valuable inputs. We enhance a Romer (1990) type endogenous growth model by a material balance condition that...

We analyze a multi-sector growth model with directed technical change where man-made capital and exhaustible resources are essen tial for production. The relative profitability of factor-specific innovations endogenously determines whether technical progress will be capital- or...

This paper introduces heterogeneity of cross-technologies interactions into the double-differentiated R&D-based endogenous growth model. In this model new technologies appear continuously and older are outdated generating structural change. All technologies may interact with each other through...
