For decades, pension systems were based on the rising revenue generated by an expanding population (demographic dividend). As changes in fertility and longevity created new population structures, however, the dividend disappeared, but pension systems failed to adapt. They are kept solvent by...

From 1850 to 2000, in Western European countries life expectancy rose from 30–40 to 80 years and the average number of children per woman fell from 4 to 5 children to slightly more than one. To gauge the economic consequences of these demographic trends, we implement an overlapping generations...

Social Accounting Matrices (SAMs) will be presented as tools that have specific features for studying the socio-economic activity of countries. Such features allow for the reading and interpretation of the reality under study, leading to the production of an empirical work that is not only...

The evidence on the inflation impact of aging is mixed, and there is no evidence regarding the volatility of inflation. Based on advanced economies' data and a DSGE-OLG model, we find that aging leads to downward pressure on inflation and higher inflation volatility. Our paper is also the first,...

Although artificial intelligence (AI) is commonly associated with anthropomorphic computers performing amazing feats, as in movies like The Matrix and Minority Report, AI is actually a much broader field of study whose results are not always mind-blowing. So what is AI? Basically, AI involves...

Using U.S. data for 1976-2013, this paper studies the effects of various macroeconomic variables, particularly the national debt, government budget deficits and taxes, on fertility decisions over the business cycle. A rise in the debt-GDP ratio, government spending-GDP ratio and the deficit-GDP...

We propose a dynamic production function of population health and mortality from birth onwards. Our parsimonious model provides an excellent fit for the mortality and survival curves for both primate and human populations since 1816. The model sheds light on the dynamics behind many phenomena...

Understanding correlations in complex systems is crucial in the face of turbulence, such as the ongoing financial crisis. However, in complex systems, such as financial systems, correlations are not constant but instead vary in time. Here we address the question of quantifying state-dependent...
