In other words, her book is now officially "a classic." At the time Jenna wrote the book few social scientists understood the distinction between a stable system (one that returns to the same spot after a disturbance) and a robust system (one that continuously adapts and maintains functionality). Jenna's book carved out a new frontier of institutional analysis that contemplates how ensembles of overlapping institutions and safeguards balance exploration and exploitation to produce robustness. Jenna stuck to her own lights in writing the book and the profession has benefited from that choice. She now deservedly joins a heady list of previous winners that includes William Riker, Paul Peterson, Alice Rivlin, and Michigan's Nancy Burns.
