To analyse the most important aspects of the Secular Stagnation hypothesis, this paper considers the effects of hysteresis in potential output in a New-Keynesian model that is extended with endogenous potential output. To do so, a number of simulations of relevant scenarios is undertaken. It is...

This paper studies the design, effects and interactions of monetary and fiscal policies in the euro-area and between the euro-area and the non euro-area. To do so, a stylized three-country model of monetary and fiscal policy rules is constructed. It is analyzed how monetary and fiscal rules...

An economy exhibits structural heterogeneity when the forecasts of different agents have different effects on the determination of aggregate variables. Various forms of structural heterogeneity can arise and we study the important case of economies in which agents' behavior depends on forecasts...

The interaction of monetary and fiscal policies is a crucial issue in a highly integrated economic area as the European Union. We argue that EMU, which introduced a common monetary policy and restrictions on fiscal policy at the national level, increases the need for macroeconomic policy...

In this paper, we analyze coordination of macroeconomic stabilization policies within the EMU by focusing, in a dynamic set-up, on asymmetries, externalities, and the existence of a multi-country context. We study how coalitions among fiscal and monetary authorities are formed and what are their...

This paper studies the institutional design of the coordination of macroeconomic stabilization policies within a monetary union in the framework of linear quadratic differential games. A central role in the analysis plays the partitioned game approach of the endogenous coalition formation...

This paper analyzes the problem of designing macroeconomic stabilization policies within the European Monetary Union (EMU) as a dynamic game between a centralized monetary authority, the European Central Bank (ECB), and national fiscal policy makers. Non-cooperative feedback Nash equilibrium and...

We study how the use of judgment or "add-factors" in forecasting may disturb the set of equilibrium outcomes when agents learn using recursive methods. We isolate conditions under which new phenomena, which we call exuberance equilibria, can exist in a standard self-referential environment....

We study how the use of judgment or "add-factors" in macroeconomic forecasting may disturb the set of equilibrium outcomes when agents learn using recursive methods. We examine the possibility of a new phenomenon, which we call exuberance equilibria, in the New Keynesian monetary policy...
