We characterize the optimal sequential choice of monetary policy in economies with either nominal or indexed debt. In a model where nominal debt is the only source of time inconsistency, the Markov-perfect equilibrium policy implies the progressive depletion of the outstanding stock of debt,...

We develop and compute a dynamic equilibrium model where economies differ on the relative efficiency of financial intermediaries and, therefore on households portfolios and currency holdings. Our model economies have some of the features of the different financial structures in countries of the...

This paper presents an empirical examination of the importance of hysteresis in international trade. An econometric model of export determination is developed where the presence of sunk costs causes discontinuous behaviour and hysteresis so that an individual exporter’s decision to stay in or...

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...

In the context of a sticky price DSGE model subject to government expenditure and preference shocks where governments issue only nominal non-contingent bonds we examine the implications for optimal inflation of changes in the level and average maturity of government debt. We analyse these...

We show how to model portfolio models in the presence of long bonds. Specifically we study optimal fiscal policy under incomplete markets where the government issues bonds of maturity N 1. Assuming the existence of long bonds introduces an additional intertemporal mechanism that makes taxes...

The booms and busts in U.S. stock prices over the post-war period can to a large extent be explained by fluctuations in investors` subjective capital gains expectations. Survey measures of these expectations display excessive optimism at market peaks and excessive pessimism at market throughs....

We study the issue of income convergence across countries and regions with a Bayesian model which allows us to use information in an efficient and flexible way. We argue that the very slow convergence rates to a common level of per-capita income found, for example, by Barro and Sala-i-Martin, is...

The aim of this Paper is to test for the extent of incompleteness in the market for US Government debt. We show that when a government pursues an optimal tax policy and issues a full set of contingent claims, the value of debt has the same or less persistence than other variables in the economy...

Introducing bounded rationality into a standard consumption based asset pricing model with a representative agent and time separable preferences strongly improves empirical performance. Learning causes momentum and mean reversion of returns and thereby excess volatility, persistence of...
