This paper studies the effects of harmonizing collateral policy in a monetary union. In 2007, the European Central Bank replaced national collateral lists with a single list specifying which assets euro area banks can pledge as collateral. Banks holding newly eligible assets experience a...

This paper provides causal evidence on the effect of credit crunches on political polarization. We combine data on bank-firm connections and electoral outcomes at the city-level during the 2008-2014 Spanish Financial Crisis. First, we show that firms in a relationship with weak banks experience...

This study assesses how banking sector integration and especially cross-border lending affect macroeconomic stability. I use a two-country general equilibrium model with heterogeneous banks that are hit by idiosyncratic shocks. According to the concept of granularity, idiosyncratic shocks to...

This paper investigates the link between mortgage supply shocks at the bank level and regional house price growth in the U.S. using micro-level data on mortgage markets from the Home Mortgage Disclosure Act for the 1990-2014 period. Our results suggest that bank-specific mortgage supply shocks...

This paper analyzes links between institutional harmonization and bilateral portfolio debt and equity holdings at the sectoral level. Motivated by the action plan for the European Capital Markets Union, we examine the potential for legal harmonization and convergence in institutional quality to...

Regulatory bank levies set incentives for banks to reduce leverage. At the same time, corporate income taxation makes funding through debt more attractive.

Since the global financial crisis and the related restructuring of banking systems, bank concentration is on the rise in many countries. Consequently, bank size and its role for macroeconomic volatility (or: stability) is the subject of intense debate. This paper analyzes the effects of...

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...

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...
