We derive Lagrange Multiplier and Likelihood Ratio specifi cation tests for the null hypotheses of multivariate normal and Student t innovations using the Generalised Hyperbolic distribution as our alternative hypothesis. We decompose the corresponding Lagrange Multiplier-type tests into...

The credit-to-GDP gap, as proposed by the Basel methodology, has become the reference measure for the activation of the Countercyclical Capital Buffer (CCyB) due to its simplicity and good predictive power for future systemic crises. However, it presents several shortcomings that could lead to...

We propose a new method for analysing multi-period stress scenarios for portfolio credit risk more systematically than in the current practice of macro stress testing. Our method quantifies the plausibility of scenarios by considering the distance of the stress scenario from an average scenario....

We conduct an extensive empirical analysis of VIX derivative valuation models before, during and after the 2008-2009 financial crisis. Since the restrictive mean reversion and heteroskedasticity features of existing models yield large distortions during the crisis, we propose generalisations...

The paper proposes a framework for assessing the impact of system-wide and bank-level capital buffers. The assessment rests on a factor-augmented vector autoregression (FAVAR) model that relates individual bank adjustments to macroeconomic dynamics. We estimate FAVAR models individually for...

We show that the distribution of any portfolio whose components jointly follow a location-scale mixture of normals can be characterised solely by its mean, variance and skewness. Under this distributional assumption, we derive the mean-variance-skewness frontier in closed form, and show that it...

We show that bank lending standards are influenced by macroeconomic conditions. We use monthly data from the Banco de España Central Credit Register, which allow us to monitor all loan applications made by non-financial firms to non-current banks from 2002 to 2015. To test the pro-cyclicality...

To identify credit availability we analyze the extensive and intensive margins of lending with loan applications and all loans granted in Spain. We find that during the period analyzed both worse economic and tighter monetary conditions reduce loan granting, especially to firms or from banks...

While banks may change their credit supply due to bank balance-sheet shocks (the local lending channel), firms can react by adjusting their sources of financing in equilibrium (the aggregate lending channel). We provide a methodology to identify the aggregate (firm-level) effects of the lending...

A common assumption in the academic literature is that franchise value plays a key role in limiting bank risk-taking. As market power is the primary source of franchise value, reduced competition in banking markets has been seen as promoting banking stability. We test this hypothesis using data...
