Personnel: Robin Hanson at George Mason University (Associate Professor of Economics)

Note: The source confirms three of four key fields: person (Robin Hanson), org (George Mason University), and role (associate professor of economics) are all explicitly stated. However, the startDate of 1999 is not mentioned in the source text. The source indicates he completed his PhD in 1997, but does not specify when he began his position at George Mason University. Without explicit confirmation of the 1999 start date, this claim is only partially verified.
