As described by my esteemed public finance colleague Jim Hines:
The Daniel M. Holland Medal has been awarded annually since 1993 for "outstanding contributions to the study and practice of public finance." It is really a great honor, reflecting lifetime achievement in public finance. Past winners include Richard Musgrave, Martin Feldstein, Harvey Rosen, Alan Auerbach, and some others - such as Arnold Harberger - who were not former Harvard students but who nonetheless had distinguished careers.
Jim has a sort of crush on Harvard, but we like him anyway.
And, more importantly, and more on point, hearty congratulations to Joel for this well deserved honor.
