Reaction Times

Reinhart and Rogoff's Growth in a Time of Debt was issued in January 2010 and caused quite a stir.

Thomas Herndon's Critique of Reinhard and Rogoff was issued more than three years later and caused quite a stir.

Gerald Friedman's What would Sanders do? was issued January 28, 2016.

Romer and Romer's Sander's Proposed Policies and Economic Growth was issued February 25, 2016 -- less than one month later and, coincidentally, Thomas Herndon's birthday -- and seems to be creating quite a stir.
