Fundamental Determinants of the Effects of Fiscal Policy

We explore the underlying determinants of the macroeconomic effects of fiscal policy and tax and social security reform using the IMF’s Global Fiscal Model (GFM). We show that the planning horizon of consumers, access to financial markets, and the elasticity of labor supply, as well as the characteristics of utility and production functions, and the degree of competition are all critical for determining the impact of fiscal policy. Four topical fiscal policy issues, for a representative large and small economy, are examined: the effects of changes in government debt, higher government spending, tax reform, and privatization of retirement savings.

Global Aging Pressures: Impact of Fiscal Adjustment, Policy Cooperation, and Structural Reforms

This paper undertakes a rigorous analysis of the effects of policies to respond to the looming demographic pressures in Europe and elsewhere. We examine the impact of fiscal adjustment by itself and when pursued in combination with tax, labor and product market reforms, using the IMF's Global Fiscal Model (GFM), calibrated to the German economy, the euro area, and the United States. We also explore the international spillover effects of demographic pressures and associated fiscal adjustment, and the benefits of cooperative action. in addition, we examine the extent to which structural reforms (including tax reform) to boost productivity growth, labor participation, and product market competition could ameliorate the adverse short-term effects of adjustment. the results suggest (i) substantial spill-over effects of aging on debt sustainability through international financial channels; (ii) the preferred adjustment package is broad-based relying on both revenue and expenditure measures while avoiding increases in direct taxes; and (ii i) there are substantial benefits from fiscal cooperation. Nonetheless, even a cooperative response has initial contractionary effects, and we show that these effects can be offset by combining fiscal adjustment with expeditious implementation of structural reforms in product and labor markets, as envisaged in the Lisbon Agenda. Moreover, the benefits accrue early and to all income-groups if the reforms are implemented as part of a package.

Strategies for fiscal consolidation in Japan

Japan's key fiscal challenge is to put public finances on a more sustainable footing. This paper investigates the macroeconomic implications of alternative fiscal strategies for Japan using the IMF's Global Fiscal Model. The results suggest that (i) an adjustment package that achieves primary balance through lower social transfers and government spending and a higher VAT is the most viable option and has a smaller negative impact on growth than other fiscal measures; (ii) achieving primary balance is not sufficient to stabilize the net debt ratio; (iii) prefunding future aging costs provides greater long-term benefits compared with less front-loaded strategies; (iv) tax reform involving shifting from corporate taxation to consumption taxation could mitigate the short-term output losses associated with fiscal consolidation; (v) the spillovers to the rest of the world from consolidation in Japan are positive in the medium term, but modest.

Global Aging Pressures: Impact of Fiscal Adjustment, Policy Cooperation, and Structural Reforms

Demographic pressures will materialize in many economies over the next few decades. We examine the macroeconomic impact of alternative fiscal adjustment and structural reform strategies to address these global aging pressures using the IMF's Global Fiscal Model (GFM). The results suggest substantial spillover effects of aging through international financial channels. To maintain sustainability, fiscal adjustment needs to be broad-based, while avoiding increases in direct taxes. There are substantial benefits from fiscal cooperation, while negative growth effects can be offset by complementary structural reforms in product and labor markets with the benefits accruing early and to all incomegroups.

Addressing Korea's Long-Term Fiscal Challenges

Korea is on the verge of an unprecedented demographic shift. In coming decades, rapid aging will transform it from one of the youngest populations in the OECD to among the oldest in record time. In turn, this shift will put tremendous pressure on the pension system and health and long-term care expenditures. This paper evaluates the impact of population aging on the long-term fiscal position in Korea, and assesses potential policy responses using the IMF's Global Fiscal Model. The paper finds that the key to maintaining a sound long-run fiscal position is to act early and with a range of policy tools, including pension reform, tax base broadening (and, if necessary, rate hikes), improved tax administration and some expenditure reallocation.

Tax and Pension Reform in the Czech Republic-Implications for Growth and Debt Sustainability

The Czech Republic has embarked on an ambitious tax reform and expenditure package to bring the deficit sustainably below 3 percent, and intends to reduce the deficit to 1 percent of GDP by 2012. To address the long-term fiscal challenge due to population aging, pension reform proposals are also being considered. In this paper we assess the macroeconomic effects of these measures using the Global Fiscal Model. The tax reform package will achieve a more efficient tax system. If implemented successfully with the intended expenditure savings measures, debt is projected to improve markedly while output would expand. Fiscal sustainability will not be restored, however, even if further measures to bring the deficit to 1 percent of GDP by 2012. Instead, raising the retirement age and prefunding future aging costs would be needed to keep debt below 60 percent of GDP through 2050.

Policy Challenges of Population Aging in Ireland

The projected rise in age-related government spending as a share of GDP in Ireland over the next forty years is among the highest in the euro area. In the absence of reforms, public debt will increase to unsustainable levels. This paper uses the IMF's Global Fiscal Model to compare the macroeconomic effects of different fiscal strategies to accommodate the rise in age-related spending. The simulations suggest that adopting a package of measures, including an increase in the retirement age, broadening the tax base, and raising indirect taxes, would be a more growth-friendly strategy than relying exclusively on raising the social security contribution rate.

Tax Reform and Debt Sustainability in Germany: An Assessment Using the Global Fiscal Model

In 2005, the German government announced a far-reaching fiscal adjustment program. This paper uses the IMF’s Global Fiscal Model to study its impact and explores options for addressing long-term pressures from population aging. The growth effects of the planned VAT increase are likely modest, largely owing to the stimulating effect of other tax reductions. The reform will improve the long-term debt path but achieving fiscal sustainability requires further adjustment over the medium term. An additional package of expenditure restraint, entitlement reform, and tax-base broadening compares favorably to other adjustment options. Spillover effects to trading partners of these policies are modest.

DSGE Modeling At the Fund: Applications and Further Developments

Researchers in policymaking institutions have expended significant effort to develop a new generation of macro models with more rigorous microfoundations. This paper provides a summary of the applications of two of these models. The Global Economy Model is a quarterly model that features a large assortment of nominal and real rigidities, which are necessary to create plausible short-run dynamics. However, because this model is based on a representative-agent paradigm, its Ricardian features make it unsuitable to study many fiscal policy issues. The Global Fiscal Model, which is an annual model that uses an overlappinggenerations structure, has been designed to analyze the longer-term consequences of alternative fiscal policies.

Jamaica and the Global Fiscal Model (GFM)

Jamaican Political leaders have so frequently cried wolf over budgetary spending that voters are skeptical about talk of budgetary crises. This is unfortunate, since deficits should arouse genuine concern, particularly as their size in developing countries like Jamaica can be daunting.

Fiscal Consolidation in Israel: A Global Fiscal Model Perspective

Fiscal consolidation has become an important policy prescription for many emerging market countries (EMCs), particularly for the highly indebted ones. Although prudent fiscal policies tend to reduce vulnerabilities, their implementation is usually postponed. This paper represents, to the best of our knowledge, one of the first attempts in the literature to quantify the costs of delaying fiscal consolidation in an EMC. In particular, using the IMF's Global Fiscal Model (GFM), we find that early consolidation through expenditure cuts would result in a substantial increase in Israel's long-term output growth relative to the case with delayed fiscal adjustment. Using an alternative fiscal instrument, we find that delaying tax cuts would result in cumulative real GDP that is much larger than otherwise.

Options for Fiscal Consolidation in the United Kingdom

This paper examines the macroeconomic effects of different timing and composition of fiscal adjustment in the United Kingdom using the IMF’s Global Fiscal Model. Early consolidation dampens aggregate demand in the short term, but increases output in the long term as smaller primary surpluses are needed as a result of lower interest payments. Reducing government transfers or current government spending provides larger gains than increasing taxes, in particular compared to raising corporate or personal income taxes. We show that these conclusions are robust under alternative behavioral assumptions and parameterizations. A reduction in global saving would make early consolidation more urgent from both cyclical and long-term perspectives. Finally, we show that tax reform aimed at increasing incentives to save could provide support to fiscal consolidation measures.
