We derive envelope theorems for optimization problems in which the value function takes values in a general Banach lattice, and not necessarily in the real line. We impose no restriction whatsoever on the choice set. Our result extend therefore the ones of Milgrom and Segal (2002). We apply our...

In this paper, we provide new evidence on the determinants of sovereign yield spreads and contagion effects in the euro area in order to evaluate the rationale for a common Eurobond jointly guaranteed by euro-area Member States. We find that default risk is the main driver of yield spreads,...

Consumption is striking back. Some recent evidence indicates that the well-known asset pricing puzzles generated by the difficulties of matching fluctuations in asset prices with high frequency fluctuations in consumption might be solved found by considering consumption in the long-run. A first...

Empirical investigations of the effects of fiscal policy shocks share a common weakness: taxes, government spending and interest rates are assumed to respond to various macroeconomic variables but not to the level of the public debt; moreover the impact of fiscal shocks on the dynamics of the...

This paper brings together two strands of the empirical macro literature:the reduced-form evidence that the yield spread helps in forecasting output and the structural evidence on the difficulties of estimating the effect of monetary policy on output in an intertemporal Euler equation. We show...

The paper explores the determinants of yield differentials between sovereign bonds in the Euro area. There is a common trend in yield differentials, which is correlated with a measure of aggregate risk. In contrast, liquidity differentials display sizeable heterogeneity and no common factor. We...

This paper studies monetary policy in the Euro area looking at the variable most directly related to current and expected monetary policy, the yield on long term government bonds. We find that the level of longterm rates in Europe is almost entirely explained by U.S. shocks and by the systematic...

We use the time series of shifts in U.S. taxes constructed by Romer and Romer to estimate tax multipliers. Differently from the single-equation approach adopted by Romer and Romer, our estimation strategy (a Var that includes output, government spending and revenues, inflation and the nominal...

In this paper we assess the possibility of producing unbiased forecasts for fiscal variables in the euro area by comparing a set of procedures that rely on different information sets and econometric techniques. In particular, we consider ARMA models, VARs, small scale semi-structural models at...

We explore the determinants of yield differentials between sovereign bonds in the Euro area. There is a common trend in yield differentials, which is correlated with a measure of the international risk factor. In contrast, liquidity differentials display sizeable heterogeneity and no common...
