Should central banks lend against low quality collateral? We characterize efficient central bank collateral policy in a model where a bank borrows from the interbank market or the central bank. Collateral has favorable incentive effects but is costly to transfer to lenders who value the...

Using security-level holdings for all euro-area investors, we study portfolio rebalancing during the quantitative easing program from March 2015 to December 2017. Foreign investors outside the euro area accommodated most of the Eurosystem's pur- chases. Duration, government credit, and corporate...

We build a model of collateral choice by banks that allows to recover the opportunity cost of collateral use and the access of banks to the interbank market. We estimate the model using country level data on assets pledged to the European Central Bank from 2009 to 2011. The model can be used to...

We build a model of collateral choice by banks to quantify how changes in the haircut policy of the central bank affect the collateral used by banks and the funding cost of banks. We estimate the model using data on assets pledged to the European Central Bank from 2009 to 2011. Our results...

Using new data on security-level portfolio holdings by investor type and across countries in the euro area, we study portfolio rebalancing during the European Central Bank's (ECB) purchase programme that started in March 2015. To quantify changes in risk concentration, we estimate the evolution...

We model mortgage refinancing as a bargaining game involving the borrowing household, the incumbent lender, and an outside bank. In equilibrium, the borrower's ability to refinance depends both on the competitiveness of the local banking market and on the cost of switching banks. We find...

We study the effect of environmental preferences on portfolio allocation around the implementation of the European Sustainable Finance Disclosure Regulation (SFDR). In a model of asset allocation with heterogeneous environmental preferences, we show that the introduction of disclosure regulation...
