Prof. Tommy Bengtsson takes us through the historical effects of short term stresses on living standards and health outcomes. How did high food prices in the nineteenth century impact the mortality risk and fertility patterns of different income classes- did it change over time? How did fetal exposure to the Spanish flu affect later life outcomes? What drives the rise in the elderly share of the population and why does it matter for solving the problems facing many pension systems? In this interview, Prof. Bengtsson guides us through each of these considerations drawing on his wealth of research in these areas.
