Beyond the power law: Uncovering stylized facts in interbank networks
Vandermarliere, Benjamin; Karas, Alexei; Ryckebusch, Jan; … - In: Physica A: Statistical Mechanics and its Applications 428 (2015) C, pp. 443-457
We use daily data on bilateral interbank exposures and monthly bank balance sheets to study network characteristics of the Russian interbank market over August 1998–October 2004. Specifically, we examine the distributions of (un)directed (un)weighted degree, nodal attributes (bank assets,...

Why is Consumption More Log Normal Than Income? Gibrat's Law Revisited
Lewbel, Arthur; Battistin, Erich; Blundell, Richard - Department of Economics, Boston College - 2007
Significant departures from log normality are observed in income data, in violation of Gibrat's law. We identify a new empirical regularity, which is that the distribution of consumption expenditures across households is, within cohorts, closer to log normal than the distribution of income. We...
