This paper introduces the Geographic Macro and Regional (GMR) model for NUTS-2 regions of the Euro zone. This model consists of three blocks: the TFP, the SCGE and the MACRO blocks. The model is built for impact analysis of policies targeting intangible assets in the forms of R&D, human capital...

This paper evaluates the temporary VAT reduction invoked by the German government over the third and fourth quarter of 2020 as part of the COVID-19 stimulus package. There is considerable controversy. Critics argue that VAT reductions are ineffective in the presence of lockdown measures in place...

This chapter discusses the Proceedings of the JRC-IEA Roundtable, which objective was to promote a technical debate on the recent developments of DSGE and alternative modelling strategies, the main mechanisms at play and their effectiveness in assessing the impact of R&D and innovation policies....

This chapter provides a description of the RHOMOLO model, a Spatial CGE model, developed and used by the European Commission for the impact assessment of policies at the regional level. Special emphasis is put on the innovation mechanisms underlying the model. Moreover, it discusses the...

This Chapter presents the NEMESIS macro-econometric model. This model has been used for several ex-ante and ex-post evaluations of the macroeconomic impact of EU R&I policies. After a general overview of the model, a thorough description of the representation of innovation in the model is...

We revisit the question whether U.S. fiscal policy in the pre-Volcker period was active or passive. To determine the policy stance, we estimate a DSGE model with monetary and fiscal policy interactions employing a sequential Monte Carlo algorithm (SMC) for posterior evaluation. In contrast to...

We investigate whether the macroeconomic effects of government spending shocks vary with the level of uncertainty. Using postwar US data and a Self-Exciting Interacted VAR (SEIVAR) model, we find that fiscal spending has positive output effects in tranquil times but is contractionary during...
