The study examined the influence of population as proximate cause of wetland dynamics in the lower Ogun river basin of southwestern, Nigeria. Both primary and secondary data were used for the study. The primary data included 100 questionnaires administered and distributed among the fadama users group representing 10% of the estimated population of the group. Satellite images of years 1972, 1984...

This paper investigates very long run pre-industrial economic development. New annual GDP per capita data for six European countries over the last seven hundred years paints a clearer picture of the history of European economic development. First, it confirms that sustained growth has been a recent phenomenon, but rejects the argument that there was no permanent growth in living standards befor...

Declines in fertility and population growth rates in the Pacific have lagged behind trends in other developing countries. In Pacific countries, most of which lack policy and public support for effective family planning and emigration outlets, rates of population growth remain among the highest in the world. The effect that high population growth rates have had in slowing economic growth appears...

This paper is concerned with the existence of the traveling bands to the Keller-Segel model with cell population growth in the form of a chemical uptake kinetics. We find that when the cell growth is considered, the profile of traveling bands, the minimum wave speed and the range of the chemical consumption rate for the existence of traveling wave solutions will change. Our results reveal that ...

Conventional R&D-based growth theory suggests that productivity growth is positively correlated with population size or population growth, an implication which is hard to see in the data. Here we integrate R&D-based growth into a unified growth setup with micro-founded fertility and schooling behavior. We then show how a Beckerian child quality-quantity trade-off explains why higher growth of p...

Nowadays, there is great diversity of economic growth in the world. This paper is going to analyze some reasons which bring about such differences and if possible, motivate rapid economic growth in the future. Herein, a lot of decisive and influential factors have been proposed and most importantly, three crucial factors of governance, technological progress, and population growth have been dis...

The Malthusian model of population and economic growth has two key components. First, there is a positive effect of the standard of living on the growth rate of population, resulting either from a purely biological effect of consumption on birth and death rates, or a behavioral response on the part of potential parents to their economic circumstances. Second, because of the existence of some fi...
