Capital Concentration and Wage Inequality

The B.E. Journal of Theoretical Economics, 2019
AbstractThis paper analyzes how capital concentration affects wage inequality through the channel of financial frictions. Higher capital concentration can be regarded as the Piketty effect. Under the framework of cost constrained financial frictions, we find that higher capital concentration will expand (resp.

A Curved Brunn-Minkowski Inequality for the Symmetric Group [PDF]

, 2015
In this paper, we construct an injection $A \times B \rightarrow M \times M$ from the product of any two nonempty subsets of the symmetric group into the square of their midpoint set, where the metric is that corresponding to the conjugacy class of ...

Harnessing the Fifth Element of Distributional Statistics for Psychological Science: A Practical Primer and Shiny App for Measures of Statistical Inequality and Concentration

Frontiers in Psychology, 2021
Although distributional inequality and concentration are important statistical concepts in many research fields (including economics, political and social science, information theory, and biology and ecology), they rarely are considered in psychological ...

A Matrix Expander Chernoff Bound

, 2018
We prove a Chernoff-type bound for sums of matrix-valued random variables sampled via a random walk on an expander, confirming a conjecture due to Wigderson and Xiao.

Multiple sets exponential concentration and higher order eigenvalues [PDF]

, 2018
On a generic metric measured space, we introduce a notion of improved concentration of measure that takes into account the parallel enlargement of k distinct sets.

Concentration inequalities for order statistics

, 2012
This note describes non-asymptotic variance and tail bounds for order statistics of samples of independent identically distributed random variables. Those bounds are checked to be asymptotically tight when the sampling distribution belongs to a maximum ...
