Consisting of 14 contributions, this volume presents a symposium on the work of Ludwig Lachmann and the Austrian School of economics, "The Legacy of Ludwig Lachmann: Interdisciplinary Perspectives on Institutions, Agency and Uncertainty," held in Johannesburg, South Africa, in April 2017, and a collection of reviews and commentaries on Nancy MacLean's Democracy in Chains. Researchers from the US, Europe, Ecuador, and South Africa discuss the capital theoretic side of the socialist calculation debate; the joint production of interpretation instruments and the relationship between institutional orders and capital structures; Lachmann's subjectivist approach to economics and its consequences and his intellectual relationship with Joseph Schumpeter; the relationship of Lachmann's views to the Austrian School of economics before, during, and after his time; his views on John Maynard Keynes and probability theory; and his public and private persona. The second section addresses the French edition of the General Theory by Keynes, followed by reviews and commentaries of MacLean's book.
