Das Public Kapital
Given the backdrop of pressing infrastructure needs, this paper argues that higher German public investment would not only stimulate domestic demand in the near term and reduce the current account surplus, but would also raise output over the longer-run as well as generate beneficial regional spillovers. While time-to-build delays can weaken the impact of the stimulus in the short-run, the expansionary effects of higher public investment are substantially strengthened with an accommodative monetary policy stance—as is typical during periods of economic slack. The current low-interest rate environment presents a window of opportunity to finance higher public investment at historically favorable rates.
The Global Integrated Monetary and Fiscal Model (GIMF) – Theoretical Structure
This working paper presents a comprehensive overview of the theoretical structure of the Global Integrated Monetary and Fiscal Model (GIMF), a multi-region dynamic general equilibrium model that is used by the IMF for a variety of tasks including policy analysis, risk analysis, and surveillance.
Assessing the Macroeconomic Impact of Structural Reforms The Case of Italy
Wide-ranging structural reforms are underway in Italy, aimed at addressing key bottlenecks in the product and labor markets. Our analysis, based on the IMF‘s Global Integrated Monetary and Fiscal model (GIMF), attempts to quantify the potential gains to the economy from a comprehensive package of structural reforms. We find that these gains can be sizeable. While in most cases, the reforms go in the right direction, their impact would depend on effective and timely implementation. In some areas, especially in the labor market, reforms would benefit from further strengthening. The priorities should be to strengthen competition in the non-tradable sector and make the labor market more efficient and inclusive, supported by growth-friendly fiscal reforms.
Fiscal Multipliers in Bulgaria
With fiscal adjustment proceeding quickly in Bulgaria and given the weak economic growth environment, there is keen interest in making the budget composition more growth friendly. This paper quantifies the short-term impact of fiscal policy on economic activity in Bulgaria using econometric and model-based approaches. While fiscal multipliers have been modest in the past, as can be expected in a small open emerging economy, the effect on output is not independent of the speed of adjustment and the specific consolidation measures used. The impact of fiscal policy on economic activity is larger in downturns than in expansions and capital spending and direct taxes are associated with the largest effects on output, while non-targeted government transfers and indirect taxes are associated with a smaller impact. The results suggest that increased capital spending financed by higher indirect tax revenue collections through base broadening has sizeable growth effects over the medium and long-term.
Australia's Linkages with China: Prospects and Ramifications of China's Economic Transition
China and Australia have increasingly strong links, especially through trade. These are driven by demand from China for Australian commodities (coal and iron ore) and services (tourism and education). These links are influenced by China’s transition to a services-driven, consumer-led economy. Using ANZIMF, the Australia-New Zealand Integrated Monetary and Fiscal model, three risks (both upside and downside) to China during this transition process are considered, focusing on their spillovers to Australia. One simple takeaway is central to each risk – while the real GDP response to shocks in Australia typically is small, responses in demand components or sectors are usually much larger– along with three further takeaways, all of which help in the analysis of Australia in relation to any risk emanating from China.
Getting to Know GIMF
The Global Integrated Monetary and Fiscal model (GIMF) is a multi-region, forward-looking, DSGE model developed by the Economic Modeling Division of the IMF for policy analysis and international economic research. Using a 5-region version of the GIMF, this paper illustrates the model’s macroeconomic properties by presenting its responses under a wide range of experiments, including fiscal, monetary, financial, demand, supply, and international shocks.
Getting to Know GMMET: The Global Macroeconomic Model for the Energy Transition
This paper presents GMMET, the Global Macroeconomic Model for the Energy Transition, and provides documentation of the model structure, data sources and model properties. GMMET is a large-scale, dynamic, non-linear, microfounded multicountry model whose purpose is to analyze the short- and medium-term macroeconomic impact of curbing greenhouse gas (GHG) emissions. The model provides a detailed description of GHG-emitting activities (related to both fossil fuel and non-fossil-fuel processes) and their interaction with the rest of the economy. To better capture real world obstacles of the energy transition, GMMET features a granular modelling of electricity generation (capturing the intermittency of renewables), transportation (capturing network externalities between charging stations and electric vehicle adoption), and fossil fuel mining (replicating estimated supply elasticities at various time horizons). The model also features a rich set of policy tools for the energy transition, including taxation of GHG emissions, various subsidies, and regulations.
The Benefits of International Policy Coordination Revisited
This paper uses two of the IMF’s DSGE models to simulate the benefits of international fiscal and macroprudential policy coordination. The key argument is that these two policies are similar in that, unlike monetary policy, they have long-run effects on the level of GDP that need to be traded off with short-run effects on the volatility of GDP. Furthermore, the short-run effects are potentially much larger than those of conventional monetary policy, especially in the presence of nonlinearities such as the zero interest rate floor, minimum capital adequacy regulations, and lending risk that depends in a convex fashion on loan-to-value ratios. As a consequence we find that coordinated fiscal and/or macroprudential policy measures can have much larger stimulus and spillover effects than what has traditionally been found in the literature on conventional monetary policy.
Spillovers in the Nordic Countries
Denmark, Finland, Norway, and Sweden form a tightly integrated region which has strong ties with the euro area as well as some exposure to Russia. Using the IMF’s Global Integrated Monetary and Fiscal model (GIMF), we examine spillovers the region could face, focusing on possible scenarios from the rest of the euro area and Russia, and the fall in global oil prices. We show that the spillovers from these scenarios differ in magnitude and impact, regardless of the high degree of integration among the four Nordic economies. These differences are driven by the fact that Denmark and Finland have no independent monetary policy, and Denmark and Norway are net energy exporters while Finland and Sweden are energy importers. We infer lessons for policy from the outcomes.
Effects of Fiscal Stimulus in Structural Models
The paper assesses, using seven structural models used heavily by policymaking institutions, the effectiveness of temporary fiscal stimulus. Models can, more easily than empirical studies, account for differences between fiscal instruments, for differences between structural characteristics of the economy, and for monetary-fiscal policy interactions. Findings are: (i) There is substantial agreement across models on the sizes of fiscal multipliers. (ii) The sizes of spending and targeted transfers multipliers are large. (iii) Fiscal policy is most effective if it has some persistence and if monetary policy accommodates it. (iv) The perception of permanent fiscal stimulus leads to significantly lower initial multipliers.
