This paper addresses the following questions. Is there evidence of financial contagion in the Eurozone? To what extent a country's vulnerability to contagion depends on "fundamentals" as opposed the government's "credibility"? We look at the empirical evidence on European sovereigns CDS spreads...

This paper provides an overview of sovereign debt portfolio risks and discusses various liability management operations (LMOs) and instruments used by public debt managers to mitigate these risks. Debt management strategies analyzed in the context of helping reach debt portfolio targets and...

We study the impact of sovereign bond auctions on secondary markets and their feedback to the sovereigns' debt cost. This linkage is established through the actions of primary dealers, participating in the auctions, and also acting as market-makers. We model financially-constrained primary...

We investigate credit default swap (CDS) and stock price reactions to a variety of credit events, including news of economic distress, financial distress, M&A, SEC probe or accounting irregularities, and leverage buyout (LBO). The CDS spread shows a large spike of 37% to 96% depending on the...

Which markets do institutions use to change exposure to credit risk? Using a unique data set of transactions in corporate bonds and credit default swaps (CDS) by large financial institutions, we show that simultaneous transactions in both markets are rare, with an average institution having an...

We use transfer entropy to quantify information flows between financial markets and propose a suitable bootstrap procedure for statistical inference. Transfer entropy is a model-free measure designed as the Kullback-Leibler distance of transition probabilities. Our approach allows to determine,...

We apply the concept of transfer entropy to quantify information flows between financial time series. Transfer entropy is a model-free measure designed as the Kullback-Leibler distance of transition probabilities. This approach allows to determine information transfer without being restricted to...

This paper studies the welfare properties of competitive equilibria in an economy with incomplete markets subject to idiosyncratic and aggregate shocks. We focus on the role of securitization, whereby borrowers can reduce idiosyncratic asset risk, which enables increased leverage and investment....

We analyze how costs related to the "plumbing" (i.e., clearing, settlement, and custody) of securities markets affect market quality and welfare. Our model compares two post-trade fee structures for allocating these costs. One charges a uniform fee for all trades, the other, marginal-cost-based...

Asset managers face increasing pressure to only hold firms that meet net-zero carbon emissions targets. We model how these mandates incentivize firms to address the global-warming externality through investments in decarbonization capital. A firm that invests receives a lower cost of capital by...
