We investigate, in a model of perfectly competitive banks and a lower bound on the deposit rate that these banks may offer, the idea that, as a result of financial innovation, capital adequacy requirements may become ineffective in preventing banks from investing in risky assets which are, from...

In this study we present a closed form solution to the moments and, in particular, correlation of two log-normally distributed random variables, when the underlying log-normal distribution is potentially truncated or censored at both tails. The closed form solution that we derive also covers the...

In this study, we reinvestigate the question of whether government banks are inferior to private banks. We use cross country data from 1993 to 2007 to trace the different types of government banks. These types comprise banks that acquire distressed banks, normal banks, or no banks at all....

In this paper, we model - quantitatively – a possible realistic interaction between a taxpayer and his Government. We formalize, in a general setting, this strategic interaction. Moreover, we analyze completely a particular realistic sample of the general model. We determine the entire payoff...

The aim of the paper is to examine the hypothesis of rent dissipation in the case of the Italian banking system during the suspension of gold convertibility. The major bank of the new born state of Italy – the Banca Nazionale nel regno d’Italia – experienced over the period 1866-1881 a...

We propose a model whereby systemic and non-systemic banks are exposed to liquidity shortfalls such that a lender of last resort policy is required. We analyze the optimal allocation of lender of last resort responsibilities and find that it is socially optimal to move responsibilities from the...

We investigate the consequences of banks' liquidity hoarding behaviour for the stability of the financial system by proposing a new model of banking contagion through two channels, bilateral exposures and funding shortage. Inspired by the key role of liquidity hoarding in the 2007-2009 financial...

The aim of the Internal Ratings Based Approach (IRBA) of Basel II was that capital suffices for unexpected losses with at least a 99.9% probability. However, because only a fraction of the required regulatory capital (a quarter to a half) had to be loss absorbing capital, the actual solvency...
