This three-volume collection contains Veblen's publications in academic journals and other scholarly press. The articles are organized under major chapters covering Veblen's pioneering thoughts on social organization; economic theory; social theory; institutions, social organization and economic performance; contemporary policies and social movements; social applications of evolutionary reasoning. Veblen made numerous seminal contributions on issues as diverse as the social role of science, the economic and social competition between entrepreneurs and engineers as well as a sobering criticism of the still under-appreciated preconceptions of economics as a science. The collection brings together much work that has been inaccessible in print and provides instructive reading for researchers on institutional economics, evolutionary economics as well as those with an interest on the history of economic thought. This edition has been professionally typeset from the original articles for easier reading and includes a comprehensive index. It is printed on quality, hard-bound volumes, resulting in an indispensable contemporary edition of Veblen's timeless ideas.
