Aggregate Fluctuations from Independent Sectoral Shocks: Self-Organized Criticality in a Model of Production and Inventory Dynamics

Scheinkman, Jose; Woodford, Michael; Bak, Peter; Chen, Kan - National Bureau of Economic Research (NBER) - 1992

This paper illustrates how fluctuations in aggregate economic activity can result from many small, independent shocks to individual sectors. The effects of the small independent shocks fail to cancel in the aggregate due to the presence of two non-standard assumptions: local interaction between...

Emergence of complex dissipative structures in the Bak–Chen–Tang forest fire model

Chen, Kan; Bak, Per - In: Physica A: Statistical Mechanics and its Applications 321 (2003) 1, pp. 256-261

The Bak–Chen–Tang forest fire model (Phys. Lett. A 147 (1999) 297) was proposed as a toy model of turbulent systems, where energy (in the form of trees) is injected uniformly and globally, but is dissipated (burns) locally. We review the existing results on the spatial and temporal...

Forest fires and the structure of the universe

Chen, Kan; Bak, Per - In: Physica A: Statistical Mechanics and its Applications 306 (2002) C, pp. 15-24

The forest fire model (Phys. Lett. A 147 (1990) 297) was proposed as a toy model of turbulent systems, where energy (in the form of trees) is injected uniformly and globally, but is dissipated (burns) locally. We found a novel scaling form for the spatial distribution of dissipation (fires) in...

Self-organization of magnetic domain patterns

Bak, Per; Flyvbjerg, Henrik - In: Physica A: Statistical Mechanics and its Applications 185 (1992) 1, pp. 3-10

We model the self-organizing dynamics of two-dimensional magnetic domain patterns with magnetic bubble traps. Avalanches of topological rearrangements and domain destruction are simulated numerically. Asymptotic forms for distributions of avalanche sizes and lifetimes are found analytically....

Self-organized criticality in non-conservative models

Bak, Per - In: Physica A: Statistical Mechanics and its Applications 191 (1992) 1, pp. 41-46

Some recent results on non-conservative models of self-organized criticality are reviewed and discussed. A class of deterministic models introduced by Olami, Feder and Christensen exhibits 1f noise with an exponent which depends on the degree of conservation. The “Game of Life”, a cellular...
