Tracking a sample of modified loans underlying private-label mortgage-backed securities, I compare the modification effectiveness of servicers who originated the loan versus those who simply service the loan. The probability of re-default among loans modified by the former is over 25% lower than...

Climate change has become a pressing issue that requires comprehensive and scientific understanding of its impact on the economy. Policymakers seek answers to the questions of how climate change affects economic growth, inflation, and the financial system. To design targeted policies, it is...

I conduct a risk analysis of Brazil’s sovereign credit. My focus is on possible changes since 2016. Using a country-level balance sheet framework, I analyze how Brazil’s liabilities pressure its assets, increasing borrowing needs and default probability. Rises in external debt, especially...

Even as banks have decreased their exposure to residential mortgage loans since 2008, bank exposure to leveraged lending has risen dramatically. The $1 trillion total asset leveraged loan market poses a significant and growing source of credit risk to U.S. depository institutions and investors....

We propose a new mortgage contract that endogenously captures the risk of house price declines to minimize default risk resulting from changes in the underlying asset value while still retaining contract rates near the cost of a standard fixed-rate mortgage. By reducing the role of the legal...

In this paper, I examine the Fed's actions in light of the...

How do banks transmit long-term central bank liquidity injections to borrowers? We exploit unique variation in how the ECB's 2011-12 Long-Term Refinancing Operations (LTROs) affected lending to firms discontinuously across credit ratings (within banks) to make four contributions. (i) We show the...

We document that banks which cut lending the most during the Great Recession were lending to the riskiest firms. Motivated by this evidence, we build a competitive matching model of bank-firm relationship, in which firms with riskier projects borrow from the banks with lower holding costs (e.g....

Central counterparty (CCP) initial margin models are procyclical by nature, and CCPs use antiprocyclicality (APC) tools to mitigate this. However, despite the widespread use of such tools, margin models of CCPs around the world reacted severely to the heightened volatility during the March 2020...

This paper studies a dynamic network economy, where risk averse traders trade multi-laterally over the counter but cannot commit to fulfil their short positions. We show that, although the level of trade is below the first-best, bilateral clearing with collateral can provide an allocation...
