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 interested in economic policy issues. This Web-only series replaced Staff Position Notes in January 2011.

Many developing and emerging countries do not fully pass-through increases in international fuel prices to domestic retail prices, with adverse consequences for fuel tax revenues and tax volatility. The adoption of an automatic fuel pricing mechanism can help to address this problem, and the incorporation of a price smoothing mechanism can ensure pass-through over the medium term but also avoid sharp increases (and decreases) in domestic prices. This technical note addresses the following issues: (i) the design of an automatic fuel pricing mechanism; (ii) the incorporation of domestic price smoothing and resulting tradeoffs; (iii) the transition from ad hoc pricing adjustments to an automatic mechanism; and (iv) policies to support this transition and the maintenance of an automatic mechanism. A standardized template for simulating and evaluating the implications of alternative pricing mechanisms for price and fiscal volatility is available on request.

This paper presents new results on the relationship between income inequality and education expansion—that is, increasing average years of schooling and reducing inequality of schooling. When dynamic panel estimation techniques are used to address issues of persistence and endogeneity, we find a large, positive, statistically significant and stable relationship between inequality of schooling and income inequality, especially in emerging and developing economies and among older age cohorts. The relationship between income inequality and average years of schooling is positive, consistent with constant or increasing returns to additional years of schooling. While this positive relationship is small and not always statistically significant, we find a statistically significant negative relationship with years of schooling of younger cohorts. Statistical tests indicate that our dynamic estimators are consistent and that our identifying instruments are valid. Policy simulations suggest that education expansion will continue to be inequality reducing. This role will diminish as countries develop, but it could be enhanced through a stronger focus on reducing inequality in the quality of education.

This paper updates estimates of fossil fuel subsidies, defined as fuel consumption times the gap between existing and efficient prices (i.e., prices warranted by supply costs, environmental costs, and revenue considerations), for 191 countries. Globally, subsidies remained large at $4.7 trillion (6.3 percent of global GDP) in 2015 and are projected at $5.2 trillion (6.5 percent of GDP) in 2017. The largest subsidizers in 2015 were China ($1.4 trillion), United States ($649 billion), Russia ($551 billion), European Union ($289 billion), and India ($209 billion). About three quarters of global subsidies are due to domestic factors—energy pricing reform thus remains largely in countries’ own national interest—while coal and petroleum together account for 85 percent of global subsidies. Efficient fossil fuel pricing in 2015 would have lowered global carbon emissions by 28 percent and fossil fuel air pollution deaths by 46 percent, and increased government revenue by 3.8 percent of GDP.

Using cross-country analysis and case studies, this book provides new insights and potential policy responses for the key fiscal policy challenges that both advanced and emerging economies will be facing.

This paper provides a comprehensive, updated picture of energy subsidies at the global and regional levels. It focuses on the broad notion of post-tax energy subsidies, which arise when consumer prices are below supply costs plus a tax to reflect environmental damage and an additional tax applied to all consumption goods to raise government revenues. Post-tax energy subsidies are dramatically higher than previously estimated, and are projected to remain high. These subsidies primarily reflect under-pricing from a domestic (rather than global) perspective, so even unilateral price reform is in countries’ own interests. The potential fiscal, environmental and welfare impacts of energy subsidy reform are substantial.

Understanding who benefits from fuel price subsidies and the welfare impact of increasing fuel prices is key to designing, and gaining public support for, subsidy reform. This paper updates evidence for developing countries on the magnitude of the welfare impact of subsidy reform and its distribution across income groups, incorporating more recent studies and expanding the number of countries. These studies confirm that a very large share of benefits from price subsidies goes to high-income households, further reinforcing existing income inequalities. The results can also help to approximate the welfare impact of subsidy reform for countries where the data necessary for such an analysis is not available.

This paper discusses two common arguments for the adoption of a UBI; that it can be a more effective way of supporting low-income households when existing safety net programs are inefficient, and that it can generate broad support for structural reforms. Using India as an illustration, the paper discusses the trade-offs that need to be recognized in adopting a UBI in these contexts. It shows that replacing the 2011 Public Distribution System (PDS) with a UBI results in losses for many low-income households, although much of this can be reduced by recycling the “out-of-system” PDS losses and the fiscal savings from excluding the highest-income groups as higher UBI transfers. In contrast, replacing inefficient energy subsidies—raising energy prices to efficient levels to internalize the negative environmental externalities of energy consumption—could simultaneously deliver unambiguous distributional gains, help address fiscal pressures, and improve energy efficiency with associated environmental and health gains. Implementing such reforms would, of course, require careful communication and implementation to address political barriers to reform.

Fiscal policy is a key tool for achieving distributional objectives in advanced economies. This paper embeds the discussion of fiscal redistribution within the standard social welfare framework, which lends itself to a transparent and practical evaluation of the extent and determinants of fiscal redistribution. Differences in fiscal redistribution are decomposed into differences in the magnitude of transfers (fiscal effort) and in the progressivity of transfers (fiscal progressivity). Fiscal progressivity is further decomposed into differences in the distribution of transfers across income groups (targeting performance) and in the social welfare returns to targeting due to varying initial levels of income inequality (targeting returns). This decomposition provides a clear distinction between the concepts of progressivity and targeting, and clarifies the relationship between them. For illustrative purposes, the framework is applied to data for 28 EU countries to determine the factors explaining differences in their fiscal redistribution and to discuss patterns in fiscal redistribution highlighted in the literature.

The setting of public utility prices involves balancing various competing government policy objectives, from equity concerns to ensuring the financial sustainability of providers and balancing public finances. In practice, public utility pricing often departs significantly from government objectives and tends to be characterized by unnecessarily complex price schedules, below cost-recovery tariff rates, and sectoral inefficiencies that contribute to large fiscal costs. Countries commonly embark on utility pricing reform in response to these heavy fiscal pressures. The paper discusses various reform options available to governments, with a focus on residential pricing schedules, highlighting their fiscal, financial, redistributive, and efficiency implications.
