This paper explores the links between macroeconomic conditions and individual bank risk. Using capital adequacy ratios as a broad measure of risk sustainability, a linear mixed effects model for a large international panel of banks for the years 2001-2005 is estimated. In OECD countries, banks...

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...

Does the mere presence of big banks affect macroeconomic outcomes? Gabaix (2011) shows that idosyncratic shocks can have aggregate effects if the distribution of firm sizes in manufacturing follows a power law distribution. Our contribution is two-fold. First, we expand the theory of granularity...

Do stock markets act as a spare tire during banking crises, providing an alternative corporate financing channel and mitigating the economic severity of these crises? Using firm-level data in 36 countries from 1990 through 2011, we find that the adverse consequences of banking crises on equity...

Procyclicality in banking may result in financial instability and therefore be destructive to economic growth. The sensitivity of different banking balance sheet and income statement variables to the business cycle is diversified and may be prone to increasing integration of financial markets....

We develop a dynamic computational network model of the banking system where fire sales provide the amplification mechanism of financial shocks. Each period a finite number of banks offers a large, but finite, number of loans to households. Banks with excess liquidity also offer loans to other...
