In the emerging consensus view on reforming bank capital requirements, the need for increased regulatory capital and some form of crisis insurance are beyond doubt, as has been established in Caballero (2009). The present paper contributes to the ongoing debate concerning the proper composition...

This work extends the contagion model introduced by Nier et al. (2007) to inhomogeneous networks. We preserve the convenient description of a financial system by a sparsely parameterized random graph but add several relevant inhomogeneities, namely well-connected banks, financial institutions...

As a result of the global financial crisis countercyclical capital requirements have been discussed to prevent financial bubbles generated in the banking sector and to mitigate the adverse effects of financial repression after a bubble burst. This paper analyses the effects of an endogenous...
