Our aim is to provide insights into some basic facts of US government debt management by introducing simple financial frictions in a Ramsey model of fiscal policy. We find that the share of short bonds in total U.S. debt is large, persistent, and highly correlated with total debt. A well known...

Rational expectations are often used as a strong argument against policy activism, as they may undermine or neutralize the policymaker’s actions. Although this sometimes happens, rational expectations do not always imply policy invariance or ineffectiveness. In fact, in certain circumstances...

Despite much work on hedging in incomplete markets, the literature still lacks tractable dynamic hedges in plausible environments. In this article, we provide a simple solution to this problem in a general incomplete-market economy in which a hedger, guided by the traditional minimum-variance...

Mean-variance criteria remain prevalent in multi-period problems, and yet not much is known about their dynamically optimal policies. We provide a fully analytical characterization of the optimal dynamic mean-variance portfolios within a general incomplete-market economy, and recover a simple...

How should aggregate public expenditures be traded off against their financing costs? We incorporate public expenditures into a standard neoclassical growth setup with model policy choice as made by a government choosing tax rates and spending so that the resulting competitive equilibrium...

We examine whether Brazilian sovereign spreads of over 20% in 2002 could be due to contagion from Argentina or to domestic politics, or both. Treating unilateral debt restructuring as a policy variable gives rise to the possibility of self-fulfilling crisis, which can be triggered by contagion....

We reconsider the optimal taxation of income from labour and capital in the stochastic growth model analysed by Chari et al. (1994, 1995), but using a linear-quadratic (LQ) approximation to derive a log-linear approximation to the optimal policy rules. The example illustrates how inaccurate...

This paper explores the relationship between the myopia, the solvency and the reputation of a government choosing the optimal financing policy given a particular path of government spending. A central result is the demonstration of a logical link between government myopia and insolvency in the...

Should rational agents take into consideration government policy announcements? A skilled agent (an econometrician) could set up a model to combine the following two pieces of information in order to anticipate the future course of fiscal policy in real-time: (i) the ex-ante path of policy as...

Motivated the European debt crisis, we construct a tractable theory of sovereign debt and structural reforms under limited commitment. The government of a sovereign country which has fallen into a recession of an uncertain duration issues one-period debt and can renege on its obligations by...
