dc.description.abstract | This work investigates the scaling properties of fluctuations in the flux of individual agents with respect to their average flux in an interbank network. The analyzed data provide information on daily values of fiasset, the credit provided by bank i in the interbank network, and filiab, the credit received by bank i from the other banks of the network. The investigation focuses on the scaling properties of the fluctuations in the raw data fiasset, filiab, and fR,iext(t)=fiasset−filiab, as well as on similar properties internal and external fluctuations fiint and fiext, which are derived according to a recently proposed methodology [ M. Argollo de Menezes and A. L. Barabasi Phys. Rev. Lett. 93 068701 (2004)]. Finally, a “rolling sampling” approach is introduced in order to deal with the nonstationarity of the fluxes. The results suggest that exponents are time varying, hinting that the considered interbank network is changing with time. | pt_BR |
