Scarring and Selection in the Great Irish Famine.

(with Matthias Blum & Eoin McLaughlin), QUCEH Working Paper Series, Paper No. 2017-08 (September 2017).

What impact do famines have on survivors? We use individual-level data on a population exposed to severe famine conditions during infancy to document two opposing effects. The first: exposure to insufficient food and a worsened disease environment is associated with poor health into adulthood – a scarring effect. The second: famine survivors do not themselves suffer any health impact – a selection effect. Anthropometric evidence from records pertaining to over 21,000 subjects born before, during and after the Great Irish Famine (1845-52), one of modern history’s most severe famine episodes, suggests that selection is strongest where famine mortality is highest. Individuals born in heavily-affected areas experienced no measurable stunted growth, while significant scarring was found only among those born in regions where the same famine did not result in any excess mortality.
