This paper examines the macroeconomic effects of tax changes during fiscal consolidations. We build a new narrative dataset of tax changes during fiscal consolidation years, containing detailed information on the expected revenue impact, motivation, and announcement and implementation dates of nearly 2,500 tax measures across 10 OECD countries. We analyze the macroeconomic impact of tax changes, distinguishing between tax rate and tax base changes, and further separating between changes in personal income, corporate income, and value added tax. Our results suggest that base broadening during fiscal consolidations leads to smaller output and employment declines compared to rate hikes, even when distinguishing between tax types.

This paper examines the macroeconomic effects of tax changes during fiscal consolidations. We build a new narrative dataset of tax changes during fiscal consolidation years, containing detailed information on the expected yield, motivation, and announcement and implementation dates of more than 2,000 tax measures across 10 OECD countries. Using this data, we then analyze the macroeconomic impact of tax changes, distinguishing between tax rate and tax base changes, and further differentiating between changes in personal income, corporate income, and value added taxes. Our results suggest that base broadening during fiscal consolidations leads to smaller output and employment declines compared to rate hikes, even when distinguishing between tax types.

Does the design of a tax matter for growth? Assembling a novel dataset for 30 OECD countries over the 1970-2016 period, this paper examines whether the value added tax (VAT) may have different effects on long-run growth depending on whether it is raised through the standard rate or through C-efficiency (a measure of the departure of the VAT from a perfectly enforced tax levied at a single rate on all consumption). Our key findings are twofold. First, for a given total tax revenue, a rise in the VAT, financed by a fall in income taxes, promotes growth only when the VAT is raised through C-efficiency. Second, for a given VAT revenue, a rise in Cefficiency, offset by a fall in the standard rate, also promotes growth. The implication is thus that in OECD countries broadening the VAT base through fewer reduced rates and exemptions is more conducive to higher long-run growth than a rise in the standard rate.

This paper reviews the theoretical and empirical literature on the effectiveness of fiscal policy. The focus is on the size of fiscal multipliers, and on the possibility that multipliers can turn negative (i.e., that fiscal contractions can be expansionary). The paper concludes that fiscal multipliers are overwhelmingly positive but small. However, there is some evidence of negative fiscal multipliers.

This paper explores how fiscal policy can affect medium- to long-term growth. It identifies the main channels through which fiscal policy can influence growth and distills practical lessons for policymakers. The particular mix of policy measures, however, will depend on country-specific conditions, capacities, and preferences. The paper draws on the Fund’s extensive technical assistance on fiscal reforms as well as several analytical studies, including a novel approach for country studies, a statistical analysis of growth accelerations following fiscal reforms, and simulations of an endogenous growth model.

This paper identifies policy tools that could be used for fiscal consolidation in advanced and emerging economies in the years ahead. The consolidation strategy, particularly in advanced countries, should aim to stabilize age-related spending in relation to GDP, reduce non-age-related expenditure ratios, and increase revenues. Bold reforms are needed to offset projected increases in age-related spending, particularly health care. On the revenue side, measures could include improving tax compliance, for example through better international cooperation, as well as increasing the yield from VAT by eliminating exemptions and reduced rates, further developing property taxes, and increasing excise rates within the range of rates already applicable in comparable countries.

This paper investigates the short-term effects of fiscal consolidation on economic activity in OECD economies. We examine the historical record, including Budget Speeches and IMFdocuments, to identify changes in fiscal policy motivated by a desire to reduce the budget deficit and not by responding to prospective economic conditions. Using this new dataset, our estimates suggest fiscal consolidation has contractionary effects on private domestic demand and GDP. By contrast, estimates based on conventional measures of the fiscal policy stance used in the literature support the expansionary fiscal contractions hypothesis but appear to be biased toward overstating expansionary effects.

This paper provides new evidence of the macroeconomic effects of public investment in advanced economies. Using public investment forecast errors to identify the causal effect of government investment in a sample of 17 OECD economies since 1985 and model simulations, the paper finds that increased public investment raises output, both in the short term and in the long term, crowds in private investment, and reduces unemployment. Several factors shape the macroeconomic effects of public investment. When there is economic slack and monetary accommodation, demand effects are stronger, and the public-debt-to-GDP ratio may actually decline. Public investment is also more effective in boosting output in countries with higher public investment efficiency and when it is financed by issuing debt.

The pamphlet (which updates the 1995 Guidelines for Fiscal Adjustment) presents the IMF’s approach to fiscal adjustment, and focuses on the role that sound government finances play in promoting macroeconomic stability and growth. Structured around five practical questions—when to adjust, how to assess the fiscal position, what makes for successful adjustment, how to carry out adjustment, and which institutions can help—it covers topics such as tax policies, debt sustainability, fiscal responsibility laws, and transparency.

The tax on immovable property has been characterized as probably the most unpopular among tax instruments, in part because it is salient and hard to avoid. But economists continue to emphasize the virtues of the property tax owing to its relatively low efficieny costs, benign impact on growth, and high score on fairness. It is, therefore, generally considered to be underutilized in most countries. This paper takes stock of the arguments for using real property taxation, and presents an updated data-set for high-and middle income countries to illustrate its use. It also reflects the renewed and widespread interest in property tax reform globally, and discusses the many policy and administrative issues that must be carefully considered as prerequisites for successful property tax reform.
