Diversification as a Process: Geographic Expansion and the Formation of National Insurers -- by Pawel Janas

I would like to thank the Linde Institute at Caltech and the Economic History Association (Cole Grant) for generous financial support. I have benefited greatly from conversations with Tracy Dennison, Phil Hoffman, Sarah Quincy, Jean-Laurent Rosenthal, Andrew Sinclair, as well as seminar participants at Caltech, Yale, and the WEAI, ASSA, and SEA annual meetings.
