Growth and Longevity from the Industrial Revolution to the Future of an Aging Society

Aging of the population will affect the growth path of all countries. To assess the historical and future importance of this claim we use two popular approaches and evaluate their merits and disadvantages by confronting them to Swedish data. We first stimulate an endogenous growth. Rising longevity increases the incentive to get education, which in turn has ever-lasting effects on growth through a human capital externality. Secondly, we consider a reduced-form statistical model based on the demographic dividend literature. Assuming that there is a common DGP guiding growth through the demographic transition, we use an estimate from post-war global data to backcast the Swedish historical GDP growth. Comparing the two approaches, encompassing tests show that each of them contains independent information on the Swedish growth path, suggesting that there is a benefit from combining them for long-term forecasting
