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...

The paper analyzes the effects of disembodied technological progress on steady state hours worked in the workhorse New-Keynesian model, which features a neoclassical labor market, and its extension that allows for equilibrium unemployment. Both versions of the model are shown to imply a positive...

[Concluding remarks] The financial crisis has rendered conventional monetary policy (of major central banks) powerless. Unconventional monetary policy, in the form of forward guidance and quantitative easing, has taken center stage. Recent moves in financial markets have challenged the notion...

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...

Some central banks have a reputation for being secretive. A justification for this behaviour that we find in the literature is that being transparent about operations and beliefs hinders the central bank in achieving the best outcome. In other words, a central bank needs flexibility and...

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 standard search model of unemployment predicts, under realistic assumptions about household preferences, that disembodied technological progress leads to higher steady-state unemployment. This prediction is at odds with the 1970s experience of slow productivity growth and high unemployment...
