We use a set of established growth models, which simultaneously include human capital and R&D, to show that the effect of mortality rate in human capital accumulation is quantitatively more important than the effect of perfectly guaranteed patents on research. First, we show that the effect of...

Early states like China, India, Italy and Greece have been experiencing more rapid economic growth in recent decades than have later-comers to agriculture and statehood like New Guinea, the Congo, and Uruguay. We show that more rapid growth by early starters has been the norm in economic...

In standard economic growth theory it is usually assumed that labor force follows exponential growth. That is not a realistic assumption. In this paper we introduce a generalized logistic equation (Richards law) that describes more accurately population growth. Then we analyze the neoclassical...

This paper is a pure theoretical attempt to explain tendencies revealed in the last decade urban researches, such as decentralization of population toward the cities suburbs, formation of polycentric cities, by a process of alteration of city traditional monocentricity, in time, due to the...

The Solow growth model assumes that labor force grows exponentially. This is not a realistic assumption because, exponential growth implies that population increases to infinity as time tends to infinity. In this paper we propose replacing the exponential population growth with a simple and more...

When the preference over intertemporal consumptions is of CIES type and human capital enters the production function in a secific way, we show that the optimum population growth rate is exactly the subjective discount rate in an infinite-horizon Ramsey Model.

This article challenges conventional wisdom by arguing that greater longevity cannot explain the significant accumulation of human capital during the transition from stagnation to growth. This is because greater longevity raises children's future income proportionally at all levels of education,...
