We develop a model of endogenous collateral requirements in the credit default swap (CDS) market. Our model provides an interpretation for the empirical findings of Capponi et al. (2020), according to which extreme tail risk measures have a higher explanatory power for observed collateral...

In response to the COVID-19 pandemic, Congress introduced foreclosure moratorium. We show that this moratorium stabilizes the housing market, lowers the Loan-to-value ratio (LTV) of households, reduces their refinancing costs, and increases equity extraction. We estimate that the moratorium...

We develop a framework for computing the total valuation adjustment (XVA) of a European claim accounting for funding costs, counterparty credit risk, and collateralization. Based on no-arbitrage arguments, we derive backward stochastic differential equations (BSDEs) associated with the...

We introduce the general arbitrage-free valuation framework for counterparty risk adjustments in presence of bilateral default risk, including default of the investor. We illustrate the symmetry in the valuation and show that the adjustment involves a long position in a put option plus a short...

This paper develops a framework to analyze the consequences of alternative designs for interbank networks, in which a failure of one bank may lead to others. Earlier work had suggested that, provided shocks were not too large (or too correlated), denser networks were preferred to more sparsely...
