Over the past few decades, the worldwide banking industry has undergone strong consolidation. As a result, the number of banks has fallen sharply. At the same time, the size of the largest banks has increased substantially, both in absolute figures and relative to the size of smaller banks. This...

This paper employs stochastic frontier cost and profit models to estimate economies of scale as well as X-efficiency for multi-billion dollar European and U.S. banks in the period 1995-1999. Empirical results with respect to separate analyses of large European and U.S. banks are strikingly...

This paper gives an overview of the recent literature on bank business models, structured along what we deem to be the three central questions when analysing business models. By doing so, we endeavour to provide the recent shift in prudential supervision towards the analysis of bank business...

This paper provides empirical evidence of behavioural responses by banks and their contribution to system-wide liquidity stress. Using firm-specific balance sheet data, we construct aggregate indicators of macro-prudential risk. Measures of size and herding show that balance sheet adjustments...

In this paper we focus on the assumption of a common efficient frontier when performing an efficiency study for the banking sector. The fact that environmental factors that are not appropriately controlled may easily bias efficiency estimates. First, we estimate a common cost and profit...

This paper considers the issue of forecasting financial fragility of banks and insurances using a panel data set of performance indicators, namely distance-to-default, taking unobserved common factors into account. We show that common factors are important in the performance of banks and...

Macro stress-testing has become an important tool to assess financial stability. This paper describes a tool kit for scenario analysis and macro stress-testing. It is based on a model which maps multivariate scenarios to banks' credit and interest rate risks by deterministic and stochastic...

In this paper we analyse the credit rating transitions of banks in Europe, the United States and Japan by using a competing risks model. We have distinguished two types of rating transitions: upgrading and downgrading. We have used some bank characteristics, like country of domicile, type of...

A persistent paradox in stochastic frontier efficiency research is that we cannot compare the X-efficiency of firms without assuming these firms to operate under a common frontier. In this paper, we address this imbalance by constructing so-called metafrontiers. Specifically, we build on recent...
