Measuring the Power of Nodes in Digraphs

Herings, P. Jean-Jacques; van der Laan, Gerard; Talman, Dolf - 2001

Many economic and social situations can be represented by a digraph. Both axiomatic and iterativemethods to determine the strength or power of all the nodes in a digraph have been proposed inthe literature. We propose a new method, where the power of a node is determined by both thenumber of its...

On the stability of cooperation structures

Haeringer, Guillaume - 2002

This paper studies the payoff structure of stable cooperation structures in link formation games. Players choose non-cooperatively with whom they want to form a link, and the payoffs are given by the Myerson value of the cooperation structure obtained. We characterize the class of TU-games that...

Generalization of Binomial Coefficients to Numbers on the Nodes of Graphs

Khmelnitskaya, Anna; van der Laan, Gerard; Talman, Dolf - 2016

of Pascal's triangle can be seen as a line-graph, to each node of which the corresponding binomial coefficient is … assigned. We show that the binomial coefficient of a node is equal to the number of ways the line-graph can be constructed when … sequences of binomial coefficients on each row of Pascal's triangle to so-called Pascal graph numbers assigned to the nodes of …

Fixed-effect regressions on network data

Jochmans, Koen; Weidner, Martin - 2017

This paper studies inference on fixed effects in a linear regression model estimated from network data. An important special case of our setup is the two-way regression model, which is a workhorse method in the analysis of matched data sets. Networks are typically quite sparse and it is...

Fixed-effect regressions on network data

Jochmans, Koen; Weidner, Martin - 2018

This paper considers inference on fixed effects in a linear regression model estimated from network data. An important special case of our setup is the two-way regression model. This is a workhorse technique in the analysis of matched data sets, such as employer-employee or student-teacher panel...

Axioms for Centrality Scoring with Principal Eigenvectors

Kitti, Mitri - 2012

represented by a directed graph and the question of ranking or scoring the alternatives can be turned into the question of … assessing the centrality of nodes of the graph. This paper characterizes the principal eigenvector as a scoring function with a …

Fixed-effect regressions on network data

Jochmans, Koen; Weidner, Martin - 2016

This paper studies inference on fixed effects in a linear regression model estimated from network data. We derive bounds on the variance of the fixed-effect estimator that uncover the importance of the smallest non-zero eigenvalue of the (normalized) Laplacian of the network and of the degree...

The Shadow of the Neolithic Revolution on Life Expectancy: A Double-Edged Sword

Franck, Raphaël; Galor, Oded; Moav, Omer; Özak, Ömer - 2022

This research explores the persistent effect of the Neolithic Revolution on the evolution of life expectancy in the course of human history. It advances the hypothesis and establishes empirically that the onset of the Neolithic Revolution and the associated rise in infectious diseases triggered...

Does democracy reduce the HIV epidemic? Evidence from Kenya

Marsaudon, Antoine; Thuilliez, Josselin - 2016

Does democracy help Kenyan citizens to struggle against the HIV epidemic? Yet, very little attention has been devoted … to establish whether political regimes react differently to the HIV infection. Using an electoral definition of democracy …-in-difference design that draws upon pre-existing variations in HIV intensity and cohort's exposure to democracy, we find that a person …
