The population growth rate, or intrinsic rate of increase, is the rate of growth that will be achieved by a population with fixed vital rates. The sensitivity of population growth rate to changes in the vital rates can be written in terms of the stable stage or age distribution and the reproductive value distribution. If the vital rate measures the rate of production of one type of individual b...

The evolution of population dynamics in a stochastic environment is analysed under a general form of density-dependence with genetic variation in r and K, the intrinsic rate of increase and carrying capacity in the average environment, and in sigma(e)(2), the environmental variance of population growth rate. The continuous-time model assumes a large population size and a stationary distribution...

During the early to mid-1990s, the pace of economic growth in the South was broadly comparable with that in the rest of the United Kingdom. During 1996–98, however, the pace of activity in the South strengthened considerably relative to the rest of the country. This article investigates one possible explanation for divergences in growth between the two regions—namely differences in the relative...

The paper analyses a model where the fight for the appropriation of rents from natural resources between two groups leads to multiple equilibria. The possibility to be trapped into the low-income equilibrium, characterized by strong social conflict (civil war) and stagnation of income, increases with the weakness of political institutions, the population growth rate, the amount of rents from na...

In 1952, India became the first country in the World to launch a family planning programme aimed at reducing population growth. But since then, as one keen observer had aptly put it, it has been “a saga of great expectations and poor performance” (Srinivasan, 1998). The overly optimistic demographic goals that have been set in various planned documents and policy statements have been continuous...

BACKGROUND Dengue cases have increased during the last decades, particularly in non-endemic areas, and Argentina was no exception in the southern transmission fringe. Although temperature rise has been blamed for this, human population growth, increased travel and inefficient vector control may also be implicated. The relative contribution of geographic, demographic and climatic of variables on...

The absorption of future population growth is one of the biggest challenges facing Papua New Guinea. Even if the fertility targets of the 1991 National Population Policy had been met, a huge increase in school places, jobs and health services would have been required. Since fertility appears not to have declined, the need for investment in social infrastructure has become even more urgent. Chri...

Rapid population growth continues in the least developed countries. The revisionist case that rapid population could be overcome by technology, that population density was advantageous, that capital shallowing is not a vital concern and that empirical investigations had not proved a correlation between high population growth and low per capita income was both empirically and theoretically flawe...
