This paper analyzes optimal fiscal policy with ambiguity aversion and endogenous government spending. We show that, without ambiguity, optimal surplus-to-output ratios are acyclical and that there is no rationale for either reduction or further accumulation of public debt. In contrast, ambiguity...

This paper analyzes optimal fiscal policy with ambiguity aversion and endogenous government spending. We show that, without ambiguity, optimal surplus-to-output ratios are acyclical and that there is no rationale for either reduction or further accumulation of public debt. In contrast, ambiguity...

We propose a new method of estimating economic uncertainty, using dispersions of forecasts of a wide range of financial, activity and inflation variables from both household and professional surveys at various frequencies. With a mixed-frequency state-space model, we construct ex-ante...

We present an Uncertainty Perception Indicator (UPI) for Germany based on the dynamic topic modelling technique RollingLDA. In contrast to conventional LDA, where all data is processed in one go, the recursive structure of RollingLDA ensures that data is made available for modeling as soon as it...

Most macroeconomic data is continuously revised as additional information becomes available. We suggest that revisions of data is an important source of uncertainty about the state of the economy. This paper evaluates the quality of major real macroeconomic Euro area variables, published by...

In this paper we investigate transmission and spillovers of local and foreign economic policy uncertainty shocks to unemployment in two largest economic regions in the world - the United States (US) and the Euro area (EA). For this purpose we deploy Bayesian Markov-switching structural vector...
