Effects of decision-making on the transport costs across complex networks

Gourley, Sean; Johnson, Neil. F. - In: Physica A: Statistical Mechanics and its Applications 363 (2006) 1, pp. 82-88

We analyse the effects of agents’ decisions on the creation of congestion on a centralised network with ring-and-hub topology. We show that there are two classes of agents each displaying a distinct set of behaviours. The dynamics of the system are driven by an interplay between the formation...

Learning and equilibrium selection in a coordination game with heterogeneous agents

Fogale, Alberto; Pellizzari, Paolo; Warglien, Massimo - In: Physica A: Statistical Mechanics and its Applications 380 (2007) C, pp. 519-527

We study a modified version of the coordination game presented in [J. van Huyck, J. Cook, R. Battalio, Selection dynamics, asymptotic stability, and adaptive behavior, J. Polit. Econ. 102 (1994) 975–1005], where a representative selection dynamics was proposed to explain experimental data....

The effects of node exclusion on the centrality measures in graph models of interacting economic agents

Caetano, Marco Antonio Leonel; Yoneyama, Takashi - In: Physica A: Statistical Mechanics and its Applications 430 (2015) C, pp. 216-223

This work concerns the study of the effects felt by a network as a whole when a specific node is perturbed. Many real world systems can be described by network models in which the interactions of the various agents can be represented as an edge of a graph. With a graph model in hand, it is...

Insolvency and contagion in the Brazilian interbank market

Souza, Sergio R.S.; Tabak, Benjamin M.; Silva, Thiago C.; … - In: Physica A: Statistical Mechanics and its Applications 431 (2015) C, pp. 140-151

This paper proposes a new way to model and analyze contagion in interbank networks. We use a unique dataset from the …, which implies that size is not the sole determinant of importance within networks. Most vulnerable financial institutions …

Synchronization by small time delays

Pruessner, G.; Cheang, S.; Jensen, H.J. - In: Physica A: Statistical Mechanics and its Applications 420 (2015) C, pp. 8-13

Synchronization is a phenomenon observed in all of the living and in much of the non-living world, for example in the heart beat, Huygens’ clocks, the flashing of fireflies and the clapping of audiences. Depending on the number of degrees of freedom involved, different mathematical approaches...

Growing network: Models following nonlinear preferential attachment rule

Zadorozhnyi, V.N.; Yudin, E.B. - In: Physica A: Statistical Mechanics and its Applications 428 (2015) C, pp. 111-132

We investigate the preferential attachment graphs proceeding from the following two assumptions. The first one: the probability that a new vertex connects to a vertex i is proportional to an arbitrary nonnegative function f of a vertex degree k. The second assumption: a new vertex can have a...
