The authors explore the relationship between fiscal rules and capital budgeting. The current budgetary approach to limit deficits to a fixed portion of GDP or to balance budgets could undermine incentives to invest in public capital with long-run returns since politicians concerned about electoral prospects would favor expenditures providing immediate benefits to their voters. An alternative budgetary approach is to separate capital from current revenues and expenditures and relax fiscal constraints by allowing governments to finance capital expenditures with debt, as suggested by the golden rule approach to capital funding. But the effect of capital budgeting would be to provide opportunities to politicians to escape the fiscal rule constraints by shifting current expenditures into capital accounts that are difficult to measure properly, thereby leading to increased borrowing. As an alternative, the authors propose a modified golden rule limiting debt finance to a proportion of the government's investment in self-liquidating assets.

What are fiscal policy rules? What are the principal benefits and drawbacks associated with various fiscal rules, particularly compared with alternative approaches to fiscal adjustment? Can fiscal rules contribute to long-run sustainability and welfare without sacrificing short-run stabilization? If so, what characteristics of fiscal rules make this contribution most effective? And in what circumstances and contexts, if any should the IMF encourage its member countries to adopt fiscal rules? This paper seeks to identify sensible fiscal policy rules that can succeed, if chosen by a member country, as an alternative to descretionary fiscal rules.

Governments often use direct subsidies or tax credits to encourage investment and promote economic growth and other development objectives. Properly designed and implemented, these incentives can advance a wide range of policy objectives (increasing employment, promoting sustainability, and reducing inequality). Yet since design and implementation are complicated, incentives have been associated with rent-seeking and wasteful public spending. This collection illustrates the different types and uses of these initiatives worldwide and examines the institutional steps that extend their value. By combining economic analysis with development impacts, regulatory issues, and policy options, these essays show not only how to increase the mobility of capital so that cities, states, nations, and regions can better attract, direct, and retain investments but also how to craft policy and compromise to ensure incentives endure.

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 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.

The paper provides evidence that fiscal rules can limit the political budget cycle. It focuses on the application of the Italian fiscal rule at the sub-national level over the period 2004-2006 and shows that: 1) municipalities are subject to political budget cycles in capital spending; 2) the Italian subnational fiscal rule introduced in 1999 has been enforced by the central government; 3) municipalities subject to the fiscal rule show more limited political budget cycles than municipalities not subject to the rule. In order to identify the effect, we rely on the fact that the domestic fiscal rule does not apply to municipalities below 5,000 inhabitants. We find that the political budget cycle increases real capital spending by about 35 percent on average in the years prior to municipal elections and that the sub-national fiscal rule reduces these figures by about two thirds.
