The politics of sovereign defaults
In this article, we study the interplay between political factors and default decisions. First, we survey two branches of theoretical studies. One shows that governments may be willing to repay their debt because it is in the best interest of local agents with political power. The other one discusses how political turnover affects sovereign default risk. Second, we describe a large body of empirical studies that find evidence of the influence of political stability and other characteristics of a political system on default risk. Finally, we examine the role of political factors in five recent ...

Life cycle patterns and boom-bust dynamics in U.S. housing prices
Home equity did not increase much for households younger than 35 years of age between 1998 and 2007 because the increase in house prices was offset by an equivalent increase in mortgage debt.

Mortgage defaults
We present a model in which households facing income and housing-price shocks use long-term mortgages to purchase houses. Interest rates on mortgages reflect the risk of default. The model accounts for observed patterns of housing consumption, mortgage borrowing, and defaults. We use the model as a laboratory to evaluate default-prevention policies. While recourse mortgages make the penalty for default harsher and thus may lower the default rate, they also lower equity and increase payments and thus may increase the default rate. Introducing loan-to-value (LTV) limits for new mortgages ...

On the evolution of income inequality in the United States
This article discusses the evolution of income inequality in the United States. We focus mainly on the evolution of inequality since the 1960s because more data are available for this period than for earlier periods. We document that income inequality rose in the United States during the period under study. Furthermore, our article documents periods characterized by a decline in real income for lower income groups. We show that the increase in inequality is concentrated among individuals with higher income and we explain that welfare inequality may have increased less than income inequality ...

Fiscal rules and the sovereign default premium
We find the optimal target values for fiscal rules and measure their aggregate effects using a model of sovereign default. We calibrate the model to an economy that pays a significant sovereign default premium when the government is not constrained by fiscal rules. For different levels of the default premium, we find that a government with a debt of 38 percent of trend income (typical in the case studied here) chooses to commit to a debt ceiling of 30 percent of trend income that starts being enforced four years after its announcement. This rule generates expectations of lower future ...
Working Paper
Sudden stops, time inconsistency, and the duration of sovereign debt
We study the sovereign debt duration chosen by the government in the context of a standard model of sovereign default. The government balances increasing the duration of its debt to mitigate rollover risk and lowering duration to mitigate the debt dilution problem. We present two main results. First, when the government decides the debt duration on a sequential basis, sudden stop risk increases the average duration by 1 year. Second, we illustrate the time inconsistency problem in the choice of sovereign debt duration: Governments would like to commit to a duration that is 1.7 years shorter ...

On the benefits of GDP-indexed government debt: lessons from a model of sovereign defaults
Whether governments should issue GDP-indexed sovereign debt continues to be the subject of policy debates. This article contributes to this debate by studying the effects of issuing GDP-indexed sovereign debt contracts using the equilibrium default model studied by Aguiar and Gopinath (2006) and Arellano (2008). We consider an extension with perfect indexation, i.e., the government issues Arrow-Debreu securities with payoffs that depend on the next-period aggregate income realization. The ex-ante welfare gain from the introduction of income-indexed bonds is equivalent to a permanent increase ...

Why could political incentives be different during election times?
Why could political incentives be different during election times? This article provides answers to this question using a career-concern model of political cycles. The analysis in the article is also relevant to understanding other agency relationships in which an important part of compensation is decided on infrequently.

What income inequality measures can (and cannot) tell us
In recent decades, income inequality has increased. But this doesn't mean that those with lower incomes are relatively worse off.
