This paper focuses on the trade-off faced by governments in deciding the allocation of public expenditures between productivity-enhancing public infrastructures and utility-enhancing public consumption. From the modeling point of view, the paper augments a standard New Open Economy...

The Flexible System of Global Models (FSGM) is a group of models developed by the Economic Modeling Division of the IMF for policy analysis. A typical module of FSGM is a multi-region, forward-looking semi-structural global model consisting of 24 regions. Using the three core modules focused on...

Using a DSGE model calibrated to the euro area, we analyze the international effects of a fiscal devaluation (FD) implemented as a revenue-neutral shift from employer's social contributions to the Value Added Tax. We find that a FD in ‘Southern European countries’ has a strong...

This paper looks at fiscal solvency and public debt sustainability in both emerging market and advanced countries. Evidence of fiscal solvency, in the form of a robust positive conditional relationship between public debt and the primary fiscal balance, is established in both groups of...

This paper proposes a probabilistic approach to public debt sustainability analysis (DSA) using "fan charts." These depict the magnitude of risks-upside and downside-surrounding public debt projections as a result of uncertain economic conditions and policies. We propose a simulation algorithm...

This paper studies, in the context of a New Open Economy Macroeconomics (NOEM) model, the effects of "public competition policies" aimed at improving the efficiency of public spending. Such measures are modeled as an increase in the price elasticity of public consumption. The paper finds that...

This paper focuses on the macroeconomic and budgetary impact of tax reforms in a New Keynesian two-country model. Our results show that both income and consumption unilateral tax rate reductions do not constitute a "free lunch", in the sense that they have negative budgetary consequences for the...

Over the past two years, the IMF staff has been developing a new multicountry macroeconomic model called the Global Economy Model (GEM). This paper explains why such a model is needed, how GEM differs from its predecessor model, and how the new features of the model can improve the IMF’s...

The IMF’s Global Integrated Monetary and Fiscal model (GIMF) is used to examine the scope for structural reforms in the euro area to offset the negative impact of fiscal consolidation required to put public debt back on a sustainable path. The results suggest that structural reforms in core...
