A Quantum-Type Approach to Non-Life Insurance Risk Modelling
Risks, 2018 A quantum mechanics approach is proposed to model non-life insurance risks and to compute the future reserve amounts and the ruin probabilities. The claim data, historical or simulated, are treated as coming from quantum observables and analyzed with ...

Probabilistic sharing solves the problem of costly punishment
New Journal of Physics, 2014 Cooperators that refuse to participate in sanctioning defectors create the second-order free-rider problem. Such cooperators will not be punished because they contribute to the public good, but they also eschew the costs associated with punishing ...

Superstatistics in Econophysics [PDF]
, 2003 We consider an ideal closed stock market, in which 100 traders have economic activities. The assets of the traders change through buying and selling stocks. We simulate the assets under conservation of both total currency and total number of stocks. If the traders are identical, then the assets are distributed as a stationary Gaussian.

Detecting global financial crises with scarce data by multivariate nonlinear filtering
Journal of Physics: ComplexityAn original procedure is devised for the automated detection of global financial crises from multivariate databases of share prices. It consists of: i) the construction of time series from the time-windowed estimations of crisis relevant information ...
