Collectivist Economic Planing With F.A. Hayek, L.V. Mises, N.G. Pierson, George Halm and Enrico Barone.
The shining star in this collection was N.G. Pierson, whose essay on value in a socialist community (1902) was exceptional: being accessible and even entertaining while presenting his ideas.
For the rest: Hayek was so-so, Halm was a snore, and Barone was mathematical to a fault.
