This paper studies the different mechanisms and the dynamics through which demography is channelled to the economy. We analyze the role of demographic changes in the economic development process by studying the transitional and the long-run impact of both the rate of population growth and the...

In this paper we assess the properties of scale-free endogenous growth models in presence of use costs for the final users. As bench-mark we use Segerstrom (2000) two R&D sector model. When use costs apply to both types of innovation we find counterintuitive results with respect to the standard...

This paper develops a multi-sectoral endogenous growth model in order to reproduce some of the essential characteristics of the so-called “ICT Revolution”. The economy consists of four sectors and the most important features are the embodied nature of technological progress, the horizontal...

We study a two-sector endogenous growth model where a single consumption good is obtained using a renewable resource in combination with physical capital. Both inputs are essential for production and technical substitutes. In this context we analyze the issues of sustainability, long-run and...

We study the one sector model of growth when a linear production technology is combined with adjustment costs and a technology for capital maintenance. Agents are allowed to under-use the installed capital and to vary the depreciation rate. This economy decides endogenously how much resources...

In this paper we study the economic determinants of the inter-sectoral distribution of skilled workers and the long-run consequences of imperfect competition on growth within an R&D-based growth model with human capital accumulation. We find that steady-state growth is driven only by incentives...

In this paper we show a method for solving in closed form a particular family of four-dimension non-linear modified Hamiltonian dynamic systems, with two states and two co-states and two co-states, which arises from a two-sector endogenous growth model where the physical capital stock is...
