We show diverse beliefs is an important propagation mechanism of fluctuations, money non neutrality and efficacy of monetary policy. Since expectations affect demand, our theory shows economic fluctuations are mostly driven by varying demand not supply shocks. Using a competitive model with...

We examine global dynamics under infinite-horizon learning in New Keynesian models where the interest-rate rule is subject to the zero lower bound. As in Evans, Guse and Honkapohja (2008), the intended steady state is locally but not globally stable. Unstable deflationary paths emerge after...

This note proposes an update to Figure 1 in "Macroeconomic Shocks and their Propagation" in the Handbook of Macroeconomics of 2016 (Ramey, 2016). Figure 1 of Ramey (2016) reports Impulse-Response Functions (IRFs) of variables of interest to a shock in the Federal Funds Rate, following the...

We study a new type of monetary-fiscal interaction in a heterogeneous-agent New Keynesian model with a fiscal block. Due to household heterogeneity, the stock of public debt affects the natural interest rate, forcing the central bank to adapt its monetary policy rule to the fiscal stance to...

The fiscal theory states that inflation adjusts so that the real value of government debt equals the present value of real primary surpluses. Monetary policy remains important. The central bank can set an interest rate target, which determines the path of expected inflation, while news about the...

We analyse the stability of countries within a monetary union in the face of asymmetric shocks, using a simple but widely applicable model. We show that members of the union may be subject to severe cycles following asymmetric shocks if there is a significant backward looking element in...

The paper identifies based on the monetary overinvestment theories by Wicksell (1898), Mises (1912) and Hayek (1929) monetary policy mistakes in large industrial countries issuing international currencies. It its argued that a neglect towards monetary policy reform in a world dominated by...

In the study, the relevance of several optimum-currency-area (OCA) criteria is formally worked out in a welfare approach. The optimum monetary-policy rules of the supranational central bank are derived within the Barro-Gordon framework, and consideration is given to how the welfare of the member...
