A comprehensive insight into Mancur Olson's work as well as extensions and applications of his work. Chapters cover three main areas: Collective Action, Institutional Sclerosis and Market-Augmenting Government. Some chapters directly assess Olson‘s contributions, focusing on distinguishing what was original in his works from what was already in the literature, and assess his impact on the fields of public economics and economic history. Other chapters present new tests and frequently extend his work. Each of the chapters is a new piece of scholarship inspired by and intended to honor Mancur Olson, and extend his influence to another generation of Collective Choice scholars and researchers.
