Paul Samuelson made a series of important contributions to population theory for humans and other species, evolutionary theory, and the theory of age structured life cycles in economic equilibrium and growth. The work is highly abstract but much of it was intended to illuminate issues of...

This paper reformulates the classical Uzawa-Lucas model of economic growth and human capital accumulation by representing time as a discrete variable and using a non-constant population growth rate. In addition, the model is developed with a more general utility function. The study examines the...

This paper studies an extension of the Mankiw-Romer-Weil growth model by departing from the standard assumption of constant population growth rate. More concretely, this rate is assumed to be decreasing over time and a general population growth law verifying this characteristic is introduced. In...

This paper studies an extension of the Ramsey growth model of optimal capital accumulation in discrete time by departing from the standard assumption of constant population growth rate. More concretely, this rate is assumed to be decreasing over time and a general population growth law with this...

Recent distressing trends in climate change, population explosion and deforestation inspired this paper, which completes existing literature by providing empirical justification to hypothetical initiatives on the impact of population growth on forest sustainability in Africa. Using three...

Purpose – Our generation is witnessing the greatest demographic transition and Africa is at the heart of it. There is mounting concern over corresponding rising unemployment and depleting per capita income. I examine the issues in this paper from a long-run perspective by assessing the...

The dynamic relationship between population and economic growth has not reached a consensus on whether it is positive, negative, or neutral. Using annual panel data for the 32 Mexican states over the period 1940-2020, this paper examines the joint dynamics of population growth and GDP per...

We develop a novel method for assessing the effect of constraints imposed by spatially-fixed natural resources on aggregate economic output. We apply it to estimate and compare the projected effects of climate change and population growth over the course of the 21st century, by country and...

The nexus of population dynamics and environmental degradation has been discussed widely in the extant literature. Most related studies have utilized carbon emission as a proxy of environmental quality. However, carbon emission does not capture the multidimensional nature of environmental...
