In theory, improvements in healthy life expectancy should generate increases in the average age of retirement, with little effect on savings rates. In many countries, however, retirement incentives in social security programs prevent retirement ages from keeping pace with changes in life expectancy, leading to an increased need for life-cycle savings. Analyzing a cross-country panel of macroeco...

Mortality, birth rates and retirement play a major role in demographic changes. In most cases, mortality rates decreased in the past century without noticeable decrease in fertility rates, this leads to a significant increase in population growth. In many poor countries like Palestinian territories the number of births has fallen and the life expectancy increased. In this article we concentrate...

Falling long-term interest rates worldwide have led some policy-makers to speculate on the emergence of a glut of global saving (Bernanke, 2005). The global trend contrasts markedly with that of the United States, where the public discussion has focused on an ongoing decline of private saving and the re-emergence of large budget deficits. The absence of saving in the United States, in conjuncti...

The speed and range of epidemic spreading is strongly influenced by the topology and dynamics of the relevant transmission network. This is, however, not a uni-directional relationship. The mutual interaction between epidemic spreading and the evolution of the transmission network is described within a new mathematical framework by a closed set of partial differential equations. This allows to ...

This paper discusses emerging demographic patterns and its opportunities and challenges for India. It investigates the specificities in the demographic transition in terms of various demographic parameters and the lack of homogeneity in the transition across states in the country. It presents some opportunities that can arise from having demographic changes, particularly the demographic dividen...

Introduction The estimated global population around 2001 was above 6 billion, out of which India accounts for more than 1 billion, second only to China. The world population is currently growing at 1.4 percent per annum as compared to India’s 1.9 percent and China’s 1 percent. According to available forecasts, India will overtake China in terms of population within the next 30 years. India's ro...

This paper develops an overlapping generations model to analyze the consequences of demographic structure changes induced by an exogenous shift in the birth rate. We …rst show that a …nite growth rate of the population that maximizes long-run capital per capita exists. Then, we examine the theoretical properties of this growth rate by showing that: (i) it corresponds to the demographic structur...

Demographers study population change across time and place, and traditionally they place a strong emphasis on a long-range view of population change. This paper builds on current reflections on how to structure the study of population change and proposes a two-stage perspective. The first stage, discovery, focuses on the production of novel evidence at the population level. The second stage, ex...
