Population Growth and Multiple Equilibria : Inferences from a Modified Ramsey Model
Lehmijoki, Ulla - 2011
The demographic transition is introduced into the otherwise standard Ramsey model to generate multiple equilibria, poverty traps, and demography-driven cycles. The model is calibrated for global data to explore the demographic conditions under which multiplicity is realized. Three cases arise,...

Life Expectancy and Economic Growth : The Role of the Demographic Transition
Cervellati, Matteo - 2009
In this paper we investigate the causal effect of life expectancy on economic growth by explicitly accounting for the role of the demographic transition. In addition to focusing on issues of empirical identification, this paper emphasizes the role of the econometric specification. We present a...

The Role of Demographics in Precipitating Crises in Financial Institutions
Macunovich, Diane J. - 2009
There are significant effects of changing demographics on economic indicators: growth in GDP especially, but also the current account balance and gross capital formation. The 15-24 age group appears to be one of the key age groups in these effects, with increases in that age group exerting...

Bose, Neha - 2020
Though many in the general public are concerned about climate change, most are unaware that agriculture and food production accounts for about one quarter of aggregate green house emissions and therefore, diet change is one of the most effective ways that individuals can reduce their climate...

Pandemic Meets Pollution : Poor Air Quality Increases Deaths by Covid-19
Isphording, Ingo Eduard - 2020
We study the impact of short-term exposure to ambient air pollution on the spread and severity of COVID-19 in Germany … patients (80+ years): higher levels of air pollution by one standard deviation 3 to 12 days after developing symptoms increase … deaths by 30 percent (males) and 35 percent (females) of the mean. In addition, air pollution raises the number of confirmed …

Life Expectancy and the Environment
Mariani, Fabio - 2009
We present an OLG model in which life expectancy and environmental quality dynamics are jointly determined. Agents may invest in environmental care, depending on how much they expect to live. In turn, environmental conditions affect life expectancy. As a result, our model produces a positive...

Pension Policies in a Model with Endogenous Fertility
Cipriani, Giam - 2018
We set up an overlapping generations model with endogenous fertility to study pensions policies in an ageing economy. We show that an increasing life expectancy may not be detrimental for the economy or the pension system itself. On the other hand, conventional policy measures, such as...

Land Reforms, Status and Population Growth
Lehmijoki, Ulla - 2014
In this document, we consider the effects of a land reform on economic and demographic growth by a family-optimization model with sharecropping, endogenous fertility and status seeking. We show that tenant farming is the major obstacle to escaping the Malthusian trap with high fertility and low...

This paper combines a multi-period economic Computable General Equilibrium (CGE) modelling framework with a demographic model to analyse the macroeconomic impact of the projected demographic trends in Scotland. Demographic trends are defined by the existing fertility-mortality rates and the...
