For a class of aggregative optimal growth models, which allow for a non-convex and non-differentiable production technology, this paper examines whether the set of utilitarian maximal programs coincides with the set of weakly maximal programs. It identifies a condition, called the...

A model with two different production sectors and endogenous growth based on the accumulation of sector-specific human capital due to learning-by-doing is presented. Accumulation of experience is measured by means of sectoral production output aggregated over time. Growth is controlled by a...

This paper presents the model of an economy subject to the mass conservation principle. The economic system is related to the environment by a flow of virgin materials into the economy, and by the diffusion of waste into the environment. Ecoefficiency contributes to reducing material waste in...

A simple rule of thumb which has been successfully used in the basic neoclassical growth model as an alternative to the unstable dynamic optimization solution is shown to be more generally applicable in a non-scale growth model with learning by doing. The model is formulated in accordance with...

It is argued that due to their general instability dynamic optimization models cannot be used as positive theories of economic growth. The argument is substantiated by (numerical) examples. A simple rule of thumb is provided as an alternative to the RKC model. This rule is shown to perform well...

Growth is associated with (i) shifts in the sectoral structure of the economy, (ii) changes in relative prices and (iii) the Kaldor facts. Moreover, (iv) cross-sectional data shows systematic differences in the expenditure structure across income groups. This paper presents a growth model which...

In this paper, starting from the two-sector Uzawa-Lucas model, we study a three-sector endogenous growth model with leisure services. By extending the endogenous growth model with leisure developed by Ladrón-de Guevara et al. [1999], our model generalizes the standard time allocation problem,...

It is well known that the performance of simple models of economic growth improves substantially through the introduction of subsistence consumption. How to compute subsistence needs, however, is a difficult and controversially discussed issue. Here, I reconsider the linear (Ak) growth model...

This paper introduces wealth-dependent time preference into a simple model of endogenous growth. The model generates adjustment dynamics in line with the historical facts on savings and economic growth in Europe from the High Middle Ages to today. Along a virtuous cycle of development more...
