This departmental paper investigates how countries in Central, Eastern, and Southeastern Europe (CESEE) can improve fiscal transparency, thereby raising government efficiency and reducing corruption vulnerabilities.

Raising revenues has been a formidable challenge for fragile and conflict-affected states (FCS), a fact confirmed once again in the COVID-19 crisis. Nonetheless, achieving sizable gains in tax collection in fragile environments is not impossible. This paper—with empirical analyses and case studies—contributes to policy discussions on tax reform in such challenging environments. Our analyses show that many FCS achieved some recovery of tax revenues, even though they found it challenging to sustain the momentum beyond three years. We also find that changes in the quality of institutions (e.g., government effectiveness and control of corruption) are a key contributory factor to their tax performance (much more so than for non-FCS). Next, we look into the tax increase episodes of four countries (Liberia, Malawi, Nepal, and the Solomon Islands). Although each FCS is unique, their experiences suggest two lessons: (i) tax reforms can be pursued even with initially weak institutions; and (ii) strong political commitment is important to sustain reform efforts and realize long-lasting, sizable gains.

How can Low-Income Countries (LICs) enhance tax revenue collection to finance their vast development needs? We address this question by analyzing seven tax reform experiences in LICs (Burkina Faso, The Gambia, Maldives, Mauritania, Rwanda, Senegal, and Uganda). Three lessons stand out, although reforms must be tailored to individual circumstances: (i) Tax reforms require first and foremost political commitment and buy-in from key stakeholders; (ii) Countries that pursue both revenue administration and tax policy reforms tend to see much larger and persistent gains; and (iii) A successful strategy often starts with fiscal reform measures with immediate effect to build momentum. These can include: simplifying the tax system; curbing exemptions; reforming indirect taxes on goods and services (e.g., excises); and better managing compliance risks through strengthening taxpayer segmentation (often beginning with strengthening the Large Taxpayers Office). A comprehensive reform strategy (e.g., a medium-term revenue strategy) can help to properly sequence reform measures and facilitate their implementation.

How do countries mobilize large additions to tax revenue - defined as an average increase in the tax-to-GDP ratio of 0.5 percent per year over three years or more? To answer this question, we build a novel dataset covering 55 episodes of large tax revenue increases in low-income countries and emerging markets. We find that: (i) reforms of indirect taxes and exemptions are the most common tax policy measures; (ii) multi-pronged tax administration reforms often go hand in hand with tax policy measures; and (iii) sustainability of the episodes hinges on tax administration reforms in the key compliance areas (risk-based audits, registration, filing, payment, and reporting).

Would countercyclical fiscal policy during recessions improve or worsen the gender employment gap? We answer this question by exploring the state-dependent impact of fiscal spending shocks on employment by gender in the G-7 countries. Using the local projection method, we find that, during recessions, a positive fiscal spending shock increases female employment more than male employment, contributing to gender employment equality. Our findings are driven by disproportionate employment changes in female-friendly industries, occupations, and part-time jobs in response to fiscal spending shocks. The analysis suggests that fiscal stimulus, particularly during recessions, could achieve the twin objectives of supporting aggregate demand and improving gender gaps.

This paper investigates the impact of low or high inflation on the public debt-to-GDP ratio in the G-7 countries. Our simulations suggest that if inflation were to fall to zero for five years, the average net debt-to-GDP ratio would increase by about 5 percentage points over the next five years. In contrast, raising inflation to 6 percent for the next five years would reduce the average net debt-to-GDP ratio by about 11 percentage points under the full Fisher effect and about 14 percentage points under the partial Fisher effect. Thus higher inflation could help reduce the public debt-to-GDP ratio somewhat in advanced economies. However, it could hardly solve the debt problem on its own and would raise significant challenges and risks. First of all, it may be difficult to create higher inflation, as evidenced by Japan’s experience in the last few decades. In addition, un-anchoring of inflation expectations could increase long-term real interest rates, distort resource allocation, reduce economic growth, and hurt the lower–income households.

Dealing with high public debt is never easy, but the current environment poses new challenges for many advanced economies. Sovereign debt is approaching historical highs, largely reflecting the work of automatic stabilizers, countercyclical fiscal policy, and financial sector bail-outs. In past episodes of debt reversals, output growth and fiscal adjustment were the main drivers. However, a weak medium-term growth outlook complicates the task of putting debt back on a clearly declining path. Thus, the burden of adjustment is shifted further on to fiscal policy at a time when fiscal accounts are already under pressure from underlying structural changes such as continued population aging and rising health care spending. And although front-loaded consolidations can have positive credibility effects and ease the pain of fiscal adjustment through lower risk premiums, they are unlikely to fully offset the short-term adverse impact on economic activity, especially in those countries in which interest rates are already low, financial fragmentation has kept lending rates elevated, or both.

task has become particularly challenging in European advanced economies where expectations of low growth and limits to monetary policy support are shifting the burden of adjustment onto fiscal consolidation. The SDN will investigate the main drivers behind successful past debt reversals, focusing on macroeconomic and financial market conditions, the speed and form of fiscal adjustment, and the institutional policy setting, among other things. Its policy conclusions will depend on the emerging stylized facts but are likely to include considerations on the design and pace of fiscal consolidation, taking into account country-specific as well as regional economic, institutional, and political factors.

Despite its vast oil wealth, central Africa still struggles to sustain strong, inclusive economic growth and to generate sufficient employment opportunities, particularly for its fast-growing youth population. Drawing on new research, Oil Wealth in Central Africa lays out the macroeconomic and growth challenges facing the region; examines oil wealth management and its implications for poverty reduction; and includes four case studies that exemplify lessons learned.
