We present an analysis of interregional consumption risk sharing in Russia between 1999 and 2009 using novel estimation methods. In addition to standard fixed-effects panel estimations, we use system and difference GMM estimators to reflect time dynamic properties and possible endogeneity between output and consumption. Furthermore, we apply spatial models that control for spatial dependence across regions. The results show that regional consumption deviations from the national average are highly persistent in time and space. Nevertheless, the regional consumption risk sharing in Russia is relatively high with 70%–90% of idiosyncratic risk being smoothed. Finally, fiscal policy and the degree of financial development appear to contribute to the consumption smoothing.

The collaboration network is an example of a social network which has both non-trivial temporal and spatial dependence. Based on the observations of collaborations in Physical Review Letters, a model of collaboration network is proposed which correctly reproduces the time evolution of the link length distributions, clustering coefficients, degree distributions, and assortative property of real data to a large extent.

Good Agreement

The time dependence of plasma radius and current is calculated on the assumption of homogeneous plasma in the case of the linear stabilised pinch effect. The comparison with the experiment shows a good conformity in regard to the contraction times. Especially it is found by theory and by experiments that the contraction times are independent of the stabilising magnetic field. Measurements of the longitudinal magnetic flux give the temporal and spatial dependence of the induced azimutal electric field in good agreement with the theory. A deviation at the beginning of the compression is attributed to the paramagnetic effect. A comparison with the theory of DREICER shows that the measured field strengths are sufficient for the production of runaway-electrons. This gives an explanation for the hard X-rays which are found in the experiments.
