The article traces the remains of the theory of “comparative institutional advantage”, which was crucial during the early development of the “varieties of capitalism” approach to economics but fell into oblivion quickly afterwards. It follows the discussions of the concept over time and works out possible reasons – theoretical, methodological, and discursive – for the theory's decay. In conclusion, many arguments of the theory seem outdated today but it is a great witness to the zeitgeist of comparative political economy and institutional theory of the millennium.
