NBER working paper

A new NBER working paper has just been released. It is titled Persistent Social Networks: Civil War Veterans who Fought Together Co-Locate in Later Life. It was written using our EI data, and co-authored by our principal investigator, a senior investigator, and a member of our Vienna staff. You may read it here.

Here is the abstract from the website:

At the end of the U.S Civil War, veterans had to choose whether to return to their prewar communities or move to new areas. The late 19th Century was a time of sharp urban growth as workers sought out the economic opportunities offered by cities. By estimating discrete choice migration models, we quantify the tradeoffs that veterans faced. Veterans were less likely to move far from their origin and avoided urban immigrant areas and high mortality risk areas. They also avoided areas that opposed the Civil War. Veterans were more likely to move to a neighborhood or a county where men from their same war company lived. This co-location evidence highlights the existence of persistent social networks. Such social networks had long-term consequences: veterans living close to war time friends enjoyed a longer life.
