Federal Reserve Chairman Ben Bernanke offered members of Princeton's Class of 2013 a tool kit for tackling their post-college lives suggestions and observations that ranged from the value and limitations of economics to an admonition to call their parents once in a while. Bernanke, a former Princeton economics professor, spoke to graduating seniors after briskly climbing to the pulpit of the University Chapel during Princeton's 266th Baccalaureate ceremony on Sunday, June 2. Baccalaureate is an interfaith worship service that is one of the University's oldest traditions.
