Available evidence supports the view that growth is faster in more open economies. In order to analyze the implications of openness and growth on determinacy and learnability of worldwide rational expectations equilibria we develop a two-country New Keynesian model with growth. We analyze these...

[Weltwirtschaftliche Dynamik flaut ab] Die Weltproduktion ist 2007 mit einer Rate von voraussichtlich 5,1 nochmals sehr kräftig gestiegen. Gegen Jahresende hat sich das Konjunkturklima jedoch deutlich eingetrübt, vor allem infolge der Immobilienkrise in den USA. Die Krise an den Finanzmärkten...

In this paper we incorporate the term structure of interest rates in a standard inflation forecast targeting framework. We find that under flexible inflation targeting and uncertainty in the degree of persistence in the economy, allowing for active learning possibilities has effects on the...

In a simple macromodel with forward-looking expectations, this Paper looks into disclosure policy when a central bank has private information on future shocks. The main result is that advance disclosure of forecasts of future shocks does not improve welfare, and in some cases is not desirable as...

In this Paper we incorporate the term structure of interest rates in a standard inflation forecast targeting framework. Learning about the transmission process of monetary policy is introduced by having heterogeneous agents - i.e. the central bank and private agents - who have different...

In a model with forward-looking expectations, the paper examines communication of central bank forecasts when the inflation target is subject to unobserved changes. It characterizes the effect of disclosure of forecasts on inflation and output stabilization and the choice of an active versus...

The paper analyzes the effects of government spending shocks under alternative rates of trend growth in a New-Keynesian model characterized by price and wage rigidity. We show that the presence of trend growth makes the impact on output and consumption of government spending shocks smaller but...

The paper studies the macroeconomic effects of government spending shocks in an economy characterized by positive trend growth. It shows that the lower is the trend growth rate the less inflationary are government spending shocks and vice versa. Moreover, on impact output is higher but exhibits...
