Bonacich Measures as Equilibria in Network Models

Salonen, Hannu - 2015

We investigate the cases when the Bonacich measures of strongly connected directed bipartite networks can be … utilitity functions, where the matrices representing the network have dimension m × n. For connected directed bipartite networks … Bonacich measures of such networks can be interpreted as a subgame perfect equilibrium path of an extensive form game with …

Bonacich Network Measures as Minimum Norm Solutions

Hannu, Salonen - 2016

An undirected connected bimodal network has two Bonacich measures quantifying the centrality of the nodes. We show that the product of Bonacich measures of an undirected bimodal network may be viewed as a product measure that is nearest (w.r.t. Euclidean norm) to the matrix representing the...

Connectedness between G10 currencies : searching for the causal structure

Bettendorf, Timo; Heinlein, Reinhold - 2019

This paper presents a new approach for modelling the connectedness between asset returns. We adapt the measure of Diebold and Yılmaz (2014), which is based on the forecast error variance decomposition of a VAR model. However, their connectedness measure hinges on critical assumptions with...

The role of interbank relationships and liquidity needs

Craig, Ben R.; Fecht, Falko; Tümer-Alkan, Günseli - 2013

In this paper, we focus on the interconnectedness of banks and the price they pay for liquidity. We assess how the concentration of credit relationships and the position of a bank in the network topology of the system influence the bank’s ability to meet its liquidity demand. We use quarterly...

The value of decentralization using the blockchain

Reuter, Marco - 2022

Although blockchain technology and cryptocurrencies have grown in popularity over the past years, there does not seem to be a consensus if they bring any value to economic interactions. In this paper, I argue that a fundamental value the blockchain provides is commitment. I develop a model of an...
