Power fluctuations in stochastic models of dissipative systems

Farago, Jean - In: Physica A: Statistical Mechanics and its Applications 331 (2004) 1, pp. 69-89

We consider different models of stochastic dissipative equations and theoretically compute the probability distribution functions (actually the associated large deviation functions) of the time averaged injected power required to sustain a nontrivial stationary state. We discuss the results and...

Statistics and dynamics

Cohen, E.G.D - In: Physica A: Statistical Mechanics and its Applications 305 (2002) 1, pp. 19-26

The classical statistics of Boltzmann and Gibbs will be discussed. As pointed out long ago by Einstein, there is a … connection of the statistics applicable to a system and its underlying dynamics. This follows, for example, from the existence of … quantum (Bose–Einstein or Fermi–Dirac) statistics, where the underlying dynamics is quite different from classical mechanics …

The maximum entropy principle and the nature of fractals

Pastor-Satorras, R; Wagensberg, J - In: Physica A: Statistical Mechanics and its Applications 251 (1998) 3, pp. 291-302

We apply the Principle of Maximum Entropy to the study of a general class of deterministic fractal sets. The scaling laws peculiar to these objects are accounted for by means of a constraint concerning the average content of information in those patterns. This constraint allows for a new...

Currency Politics: The Political Economy of Exchange Rate Policy

Frieden, Jeffry A. - Princeton University Press

The exchange rate is the most important price in any economy, since it affects all other prices. Exchange rates are set, either directly or indirectly, by government policy. Exchange rates are also central to the global economy, for they profoundly influence all international economic activity....

Universal fluctuations of the AEX index

Gonçalves, Rui; Ferreira, Helena; Stollenwerk, Nico; … - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 21, pp. 4776-4784

We compute the analytic expression of the probability distributions FAEX,+ and FAEX,− of the normalized positive and negative AEX (Netherlands) index daily returns r(t). Furthermore, we define the α re-scaled AEX daily index positive returns r(t)α and negative returns (−r(t))α, which we...

Ups and downs of economics and econophysics — Facebook forecast

Gajic, Nenad; Budinski-Petkovic, Ljuba - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 1, pp. 208-214

What is econophysics and its relationship with economics? What is the state of economics after the global economic crisis, and is there a future for the paradigm of market equilibrium, with imaginary perfect competition and rational agents? Can the next paradigm of economics adopt important...

Enlightenment from various conditional probabilities about Hang Seng index in Hong Kong stock market

Chen, Huiping; Sun, Xia; Wu, Ziqin; Wang, Binghong - In: Physica A: Statistical Mechanics and its Applications 335 (2004) 1, pp. 183-196

The daily Hang Seng index in the Hong Kong stock market has been analyzed in this paper. Two kinds of sign sequences as given conditions have been used to predict the future price movements. One is the parameter of multifractal spectrum Δf based on the indexes recorded in every minute, and the...
