What Influences Banks' Choice of Risk Management Tools? Theory and Evidence

This paper investigates the factors influencing banks' decision to engage in advanced risk management, from both a theoretical and an empirical perspective. In recent decades, credit risk management in banks has become highly sophisticated and banks have become more active and advanced in the management of credit risks. We identify two driving factors for risk management: bank competition and sector ...

Big Banks and Macroeconomic Outcomes: Theory and Cross-Country Evidence of Granularity

Does the mere presence of big banks affect macroeconomic outcomes? In this paper, we develop a theory of granularity (Gabaix, 2011) for the banking sector, introducing Bertrand competition and heterogeneous banks charging variable markups. Using this framework, we show conditions under which idiosyncratic shocks to bank lending can generate aggregate fluctuations in the credit supply when the banking ...

Granularity in Banking and Growth: Does Financial Openness Matter?

We explore the impact of large banks and of financial openness for aggregate growth. Large banks matter because of granular effects: if markets are very concentrated in terms of the size distribution of banks, idiosyncratic shocks at the bank-level do not cancel out in the aggregate but can affect macroeconomic outcomes. Financial openness may affect GDP growth in and of itself, and it may also influence ...

Cross-Border Banking, Bank Market Structures and Market Power: Theory and Cross-Country Evidence

Patterns in cross-border banking have changed since the global financial crisis. This may affect domestic bank market structures and macroeconomic stability in the longer term. In this study, I theoretically and empirically analyze how different modes of cross-border banking impact bank concentration. I use a two- country general equilibrium model with heterogeneous banks developed by De Blas and Russ ...

Capital Controls and Macroprudential Measures: What Are They Good For?

Are capital controls and macroprudential measures successful in achieving their objectives? Assessing their effectiveness is complicated by selection bias and endogeneity; countries which change their capital-flow management measures (CFMs) often share specific characteristics and are responding to changes in variables that the CFMs are intended to influence. This paper addresses these challenges by ...

Big Banks and Macroeconomic Outcomes

Bank Lending Procyclicality and Credit Quality during Financial Crises

This paper analyses macroeconomic and financial determinants of bad loans applying a SVAR approach to investigate whether excessive loans granted during expansionary phases can explain the more than proportional increase in non-performing loans during contractionary periods. The results indicate that the effects of a permanent shock to bad loans on the excess of credit are significant and persistent ...

Implicit State Guarantees Exacerbate Problem: Separated Banking System Alone Not a Solution

Many banks are now too big, complex, and closely interconnected to be liquidated. When they run into difficulties, they threaten the entire financial system of their economic area. Five years of financial crisis have not alleviated but exacerbated this problem. The cost of stabilizing banks is enormous, posing serious challenges to the states affected. In addition, such state guarantees create dangerously ...
