In a number of oil producing countries, oil revenue accounts for the majority of government revenue, but is expected to be depleted in a relatively short time frame. Ensuring that fiscal policy is on a sustainable path is thus a high priority, but political and social adjustment costs create...

With the public finances of many developing and emerging market countries still heavily dependent on trade tax revenues, further trade liberalization may be hindered unless they are able to develop alternative sources of revenue. While there is now a well-established body of theory and policy...

While models based on Friedman's (1957) permanent-income hypothesis can provide oilproducing countries with long-run fiscal targets, they usually abstract from short-run costs associated with consolidation. This paper proposes a model that takes such adjustment costs (or "habits") into account....

Rising longevity, falling fertility rates, and the retirement of the baby boom generation will substantially raise age-related government spending in most advanced and many emerging market countries. This paper assesses the evolution of fiscal sustainability for each of the G-7 countries using...

Has the VAT proved, as its proponents claim, an especially effective form of taxation? To address this, this paper first shows that a tax innovation-such as the introduction of a VAT- reduces the marginal cost of public funds if and only if it also leads an optimizing government to increase the...

This paper presents a new dataset of fiscal consolidation for 17 OECD economies during 1978-2009. We focus on discretionary changes in taxes and government spending primarily motivated by a desire to reduce the budget deficit and not by a response to prospective economic conditions. To identify...

This paper investigates the relation between growth forecast errors and planned fiscal consolidation during the crisis. We find that, in advanced economies, stronger planned fiscal consolidation has been associated with lower growth than expected, with the relation being particularly strong,...

Staff Discussion Notes showcase the latest policy-related analysis and research being developed by individual IMF staff and are published to elicit comment and to further debate. These papers are generally brief and written in nontechnical language, and so are aimed at a broad audience...

One of the most striking tax developments in recent years, and one that continues to attract considerable attention, is the adoption by several countries of a form of "flat tax." Discussion of these quite radical reforms has been marked, however, more by assertion and rhetoric than by analysis...

This paper evaluates the nature and extent of, and possible responses to, two of the central challenges that globalization poses for revenue mobilization in Sub-Saharan Africa (SSA): from corporate tax competition, and from trade liberalization. It does so using a new dataset with features...
