Fiscal Stimulus Under Sovereign Risk
The excess procyclicality of fiscal policy is commonly viewed as a central malaise in emerging economies. We document that procyclicality is more pervasive in countries with higher sovereign risk and provide a model of optimal fiscal policy with nominal rigidities and endogenous sovereign default that can account for this empirical pattern. Financing a fiscal stimulus is costly for risky countries and can render countercyclical policies undesirable, even in the presence of large Keynesian stabilization gains. We also show that imposing austerity can backfire by exacerbating the exposure to ...

Sovereign Risk and Fiscal Information: A Look at the U.S. State Default of the 1840s
This paper examines how newspaper reporting affects government bond prices during the U.S. state default of the 1840s. Using unsupervised machine learning algorithms, the paper first constructs novel ``fiscal information indices'' for state governments based on U.S. newspapers at the time. The impact of the indices on government bond prices varied over time. Before the crisis, the entry of new western states into the bond market spurred competition: more state-specific fiscal news imposed downward pressure on bond prices for established states in the market. During the crisis, more ...

Efficient Computation with Taste Shocks
Taste shocks result in nondegenerate choice probabilities, smooth policy functions, continuous demand correspondences, and reduced computational errors. They also cause significant computational cost when the number of choices is large. However, I show that, in many economic models, a numerically equivalent approximation may be obtained extremely efficiently. If the objective function has increasing differences (a condition closely tied to policy function monotonicity) or is concave in a discrete sense, the proposed algorithms are O(n log n) for n states and n choice--a drastic improvement ...

Relationship Networks in Banking Around a Sovereign Default and Currency Crisis
We study how banks? exposure to a sovereign crisis gets transmitted onto the corporate sector. To do so we use data on the universe of banks and ?rms in Argentina during the crisis of 2001. We build a model characterized by matching frictions in which ?rms establish (long-term) relationships with banks that are subject to balance sheet disruptions. Credit relationships with banks more exposed to the crisis su?er the most. However, this relationship-level e?ect overstates the true cost of the crisis since profitable ?rms (e.g., exporters after a devaluation) might ?nd it optimal to switch ...

Selective Sovereign Defaults
Governments issue debt both domestically and abroad. This heterogeneity introduces the possibility for governments to operate selective defaults that discriminate across investors. Using a novel dataset on the legal jurisdiction of sovereign defaults that distinguishes between defaults under domestic law and default under foreign law, we show that selectiveness is the norm and that imports, credit, and output dynamics are different around different types of default. Domestic defaults are associated with contractions of credit and are more likely in countries with smaller credit markets. In ...
