We study the welfare properties of a general equilibrium banking model with moral hazard that encompasses incentive mechanisms for bank risk-taking studied in a large partial equilibrium literature. We show that competitive equilibriums maximize welfare and yield an optimal level of banks' risk...

The number of firm bankruptcies is surprisingly low in economies with poor institutions. We study a model of bank-firm relationship and show that the bank?s decision to liquidate bad firms has two opposing effects. First, the bank receives a payoff if a firm is liquidated. Second, it loses the...

The theoretical literature gives conflicting predictions on how bank competition should affect financial stability, and dozens of researchers have attempted to evaluate the relationship empirically. We collect 598 estimates of the competitionstability nexus reported in 31 studies and analyze the...

This study investigates the bank competition-stability nexus using a unique regulatory dataset provided by the Deutsche Bundesbank over the period 1994 to 2010. First, we use outright bank defaults as the most direct measure of bank risk available and contrast the results to weaker forms of bank...

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...

It has been argued that competing banks make inefficiently frequent use of collateralization in situations where they are better able to evaluate a project's risk than entrepreneurs. We study the bank's choice between screening and collateralization in a model where banks do not have this...

We analyze the relationship between bank size and risk-taking under the New Basel Capital Accord. Using a model with imperfect competition and moral hazard, we show that the introduction of an internal ratings based (IRB) approach improves upon flat capital requirements if the approach is...

We study the effects of competition on loan rates and portfolio-at-risk in microcredit markets using a new database from rating agencies, covering 379 microbanks located in 67 countries between 2002 and 2008. Our study reveals different competitive effects in nonprofit and for-profit microbanks....

This report analyses the main developments in housing finance in the euro area in the decade, covering the period from 1999 to 2007. It looks at mortgage indebtedness, various characteristics of loans for house purchase, the funding of such loans and the spreads between the interest rates on...

This paper investigated the changes in competitive behaviour of banks in sub-Saharan Africa, following the 2007/2008 global financial crisis. Using 481 bank-year observations from an unbalanced panel of 83 banks from six countries over the period 2008-2013. We employed the Panzar-Rosse model of...
