A square matrix is said to be doubly stochastic if its entries are all non-negative and each row and column sums to one, i.e. The Birkhoff polytope, denoted by , is the set of all doubly stochastic matrices. One interesting fact about the Birkhoff polytope is that it is a convex polytope, with the vertices […]

ASSA 2023 part two: the radical – monopoly and war
In some ways, the radical sessions at ASSA were disappointing. As far as I could tell there were no papers on the causes of the rise in inflation or on what policies to adopt to support labour on this issue. Maybe this is sour grapes from me, as URPE rejected my own paper on a […]
