We study how banks manage their liquidity among the various assets at their disposal. We exploit the introduction of the ECB's two-tier system which heterogeneously reduced the cost of additional reserves holdings. We find that the treated banks increase reserve holdings by borrowing on the...

Protection buyers use derivatives to share risk with protection sellers, whose assets are only imperfectly pledgeable because of moral hazard. To mitigate moral hazard, privately optimal derivative contracts involve variation margins. When margins are called, protection sellers must liquidate...

In this paper, we survey the nascent literature on the transmission of negative policy rates. We discuss the theory of how the transmission depends on bank balance sheets, and how this changes once policy rates become negative. We review the growing evidence that negative policy rates are...

Using new quarterly narrative evidence, this paper examines the macroeconomic impact of reforms of unemployment benefits (UB) and employment protection legislation (EPL) in the euro area from a Bayesian narrative panel VAR. The approach complements existing micro-econometric evidence by aligning...

This paper shows that there is a natural trade-off when designing market based executive compensation. The benefit of market based pay is that the stock price aggregates speculators’ dispersed information and there-fore takes a picture of managerial performance before the long-term value of a...

This paper examines the role of collateral in the financial system, with special emphasis on the implications for financial stability and the conduct of monetary policy. First, we review what drives the demand and supply for both real and financial collateral assets. Then we examine financial...

We show that negative policy rates affect the supply of bank credit in a novel way. Banks are reluctant to pass on negative rates to depositors, which increases the funding cost of high-deposit banks, and reduces their net worth, relative to low-deposit banks. As a consequence, the introduction...

We analyze optimal hedging contracts and show that although hedging aims at sharing risk, it can lead to more risk-taking. News implying that a hedge is likely to be loss-making undermines the risk-prevention incentives of the protection seller. This incentive problem limits the capacity to...

We offer a theoretical framework to analyze corporate lending when loan officers must be incentivized to prospect for loans and to transmit the soft information they obtain in that process. We explore how this multi-task agency problem shapes loan officers' compensation, banks' use of soft...

We study the optimal design of clearing systems. We analyze how counterparty risk should be allocated, whether traders should be fully insured against that risk, and how moral hazard affects the optimal allocation of risk. The main advantage of centralized clearing, as opposed to no or...
