Fiscal Monitor October 2017

At the global level, inequality has declined substantially over the past three decades, but within national boundaries, the picture is mixed: some countries have experienced a reduction in inequality while others, particularly advanced economies, have seen a significant increase that has, among other things, contributed to growing public backlash against globalization. Excessive levels of inequality can erode social cohesion, lead to political polarization, and ultimately lower economic growth, but whether inequality is excessive depends on country-specific factors, including the growth context in which inequality arises, along with societal preferences. This Fiscal Monitor focuses on how fiscal policy can help governments address high levels of inequality while minimizing potential trade-offs between efficiency and equity. It documents recent trends in income inequality, including inequality both between and within countries, then examines the redistributive role of fiscal policies over recent decades and underscores the importance of appropriate design to minimize any efficiency costs. It then focuses on some key components of fiscal redistribution: progressivity of income taxation, universal basic income, and public spending policies for achieving more equitable education and health outcomes. The analysis relies on the existing theoretical and empirical literature, IMF work on inequality and fiscal policy, country experiences, and new analytical work, including various static microsimulation analyses based on household survey data. Simulations using a dynamic general equilibrium model calibrated to country-specific data and behavioral parameters illustrate the potential impact of alternative budget-neutral tax and transfer measures on income inequality and economic growth.

This report emphasizes the environmental, fiscal, economic, and administrative case for using carbon taxes, or similar pricing schemes such as emission trading systems, to implement climate mitigation strategies. It provides a quantitative framework for understanding their effects and trade-offs with other instruments and applies it to the largest advanced and emerging economies. Alternative approaches, like “feebates” to impose fees on high polluters and give rebates to cleaner energy users, can play an important role when higher energy prices are difficult politically. At the international level, the report calls for a carbon price floor arrangement among large emitters, designed flexibly to accommodate equity considerations and constraints on national policies. The report estimates the consequences of carbon pricing and redistribution of its revenues for inequality across households. Strategies for enhancing the political acceptability of carbon pricing are discussed, along with supporting measures to promote clean technology investments.

Public sector balance sheets provide the most comprehensive picture of public wealth. They bring together all the accumulated assets and liabilities that the government controls, including public corporations, natural resources, and pension liabilities. They thus account for the entirety of what the state owns and owes, offering a broader fiscal picture beyond debt and deficits. Most governments do not provide such transparency, thereby avoiding the additional scrutiny it brings. Better balance sheet management enables countries to increase revenues, reduce risks, and improve fiscal policymaking. There is some empirical evidence that financial markets are increasingly paying attention to the entire government balance sheet and that strong balance sheets enhance economic resilience. This issue of the Fiscal Monitor presents a new database that shows comprehensive estimates of public sector assets and liabilities for a broad sample of 31 countries, covering 61 percent of the global economy, and provides tools to analyze and manage public wealth. Estimates of public wealth reveal the full scale of public assets and liabilities. Assets are worth US$101 trillion or 219 percent of GDP in the sample. This includes 120 percent of GDP in public corporation assets. Also included are natural resources that average 110 percent of GDP among the large natural-resource-producing countries. Recognizing these assets does not negate the vulnerabilities associated with the standard measure of general government public debt, comprising 94 percent of GDP for these countries. This is only half of total public sector liabilities of 198 percent of GDP, which also includes 46 percent of GDP in already accrued pension liabilities. Once governments understand the size and nature of public assets, they can start managing them more effectively. Potential gains from better asset management are considerable. Revenue gains from nonfinancial public corporations and government financial assets alone could be as high as 3 percent of GDP a year, equivalent to annual corporate tax collections across advanced economies. In addition, considerable gains could be realized from government nonfinancial assets. Public assets are a significant resource, and how governments use and report on them matters, not just for financial reasons, but also in terms of improving service delivery and preventing the misuse of resources that often results from a lack of transparency.

The report explores how fiscal policy can foster resilience by protecting households against large income and employment losses. Governments face increasingly difficult trade-offs in tackling the spikes in food and energy prices when policy buffers are largely exhausted after two years of pandemic. They should prioritize protecting vulnerable groups through targeted support while keeping a tight fiscal stance to help reduce inflation. Building fiscal buffers in normal times would allow governments to respond swiftly and flexibly during adversities. Several fiscal tools, such as job-retention schemes, have proven useful to preserve jobs and income for workers. Social safety nets should be made more readily scalable and better targeted, leveraging digital technologies. Exceptional support to firms should be reserved for severe situations and requires sound fiscal risk management.

This report discusses fiscal policies to prepare for the next downturn and foster long-term inclusive growth by adapting to changing demographics, advancing technology, and deepening global integration. It also covers recent fiscal developments and the fiscal outlook in advanced economies, emerging markets, and low-income developing countries; recent trends in government debt and analysis of changes in fiscal balances, revenue, and spending; and potential fiscal risks. The report takes on in-depth look at how corruption impacts government policies and operations, the fiscal costs, and how fiscal institutions can help fight corruption.

This report discusses fiscal trends in policies aimed at reducing fiscal vulnerabilities and boosting medium-term growth, recent fiscal developments and the fiscal outlook in advanced economies, emerging markets, and low-income developing countries; recent trends in government debt and analysis of changes in fiscal balances, revenue, and spending; potential fiscal risks; and growth from the fiscal policies. It also describes how digitalization can help governments improve implementation of current policy and widen the range of policy options, and opportunities and risks for fiscal policy, including improvements in policy implementation, the design of future policy, and how digitalization can create opportunities for fraud and increase government vulnerabilities.

Chapter 1 discusses how fiscal policy operates amid a sharp rise in uncertainty caused by the war in Ukraine. Chapter 2 discusses how international coordination on tax matters can support revenue, inclusion, tax transparency, and greener economies.
