ow do credit default swaps (CDS) affect sovereign debt markets? The answer depends crucially on trading frictions, risk-sharing, arbitrage violations, and spillovers from secondary to primary markets. We propose a sovereign default model where investors trade bonds and CDS over the counter via...

Theoretical formulations of dynamic heterogeneous-agent economiestypically include a distribution as an aggregate state variable. This paperintroduces a method for computing equilibrium of these models by including a distribution directly as a state variable if it is finite-dimensional or a fine...

How does physical capital accumulation affect the decision to default in developing small open economies? We find that, conditional on a level of foreign indebtedness, more capital improves the sovereign’s ability to meet its obligations, reducing the likelihood of default and the risk...

Motivated by the recent experience of the U.S. and the Eurozone, the authors describe the quantitative properties of a New Keynesian model with a zero lower bound (ZLB) on nominal interest rates, explicitly accounting for the nonlinearities that the bound brings. Besides showing how such a model...

A divide-and-conquer algorithm for exploiting policy function monotonicity is proposed and analyzed. To compute a discrete problem with n states and n choices, the algorithm requires at most 5n + log2(n)n function evaluations and so is O(n log2 n). In contrast, existing methods for non-concave...

Bonds are an important source of funding for municipalities. As financing for big budget construction projects or surprise shortfalls in tax revenue, bonds help smooth tax burden across time. There is good reason for this smoothing: if residents feel their tax burden is excessive, they can...
