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 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 mobilization 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 or are stand alone; and (iii) sustainability of the episodes hinges on tax administration reforms in the key compliance areas (risk-based audits, registration, filing, payment, and reporting).

Global growth is projected to slow significantly in the second half of this year, with weakness continuing in 2024. Inflation pressures persist, and tight monetary policy is expected to weigh substantially on activity. The possibility of more widespread bank turmoil and tighter monetary policy could result in even weaker global growth. Rising borrowing costs in advanced economies could lead to financial dislocations in the more vulnerable emerging market and developing economies (EMDEs). In low-income countries, in particular, fiscal positions are increasingly precarious. Comprehensive policy action is needed at the global and national levels to foster macroeconomic and financial stability. Among many EMDEs, and especially in low-income countries, bolstering fiscal sustainability will require generating higher revenues, making spending more efficient, and improving debt management practices. Continued international cooperation is also necessary to tackle climate change, support populations affected by crises and hunger, and provide debt relief where needed. In the longer term, reversing a projected decline in EMDE potential growth will require reforms to bolster physical and human capital and labor-supply growth.

This Selected Issues paper discusses a growth-at-risk (GaR) model which is used to compute a distribution of expected GDP growth for Benin. The model predicts growth rates of ~6.7 percent for 2019 and a range of 6.4–6.8 percent in the medium-term (depending on the specification). Risks to future growth are assessed to be tilted to the downside. 2019 GDP growth is estimated around 6.7 percent, on average, across several specifications. The model considers external factors (world trade, global financial conditions, trade policy uncertainty, and US consumer sentiment), country-specific exposures to external factors (commodity terms of trade and trade-partner growth), and domestic factors (domestic financial conditions, fiscal policy, and the exchange rate). The analysis reveals that growth projections estimated both for the median and mode are slightly higher conditioned on 2018 data, yet when expectations about 2019 are considered using World Economic Outlook projections they fall. Overall, risks seem to be tilted to the downside. Medium term growth is estimated at between 6.4 and 6.8 percent. Risks to growth remain tilted to the downside, yet less skewed than in the short term.

Despite strong economic growth since 2000, many low-income countries (LICs) still face numerous macroeconomic challenges, even prior to the COVID-19 pandemic. Despite the deceleration in real GDP growth during the 2008 global financial crisis, LICs on average saw 4.5 percent of real GDP growth during 2000 to 2014, making progress in economic convergence toward higher-income countries. However, the commodity price collapse in 2014–15 hit many commodity-exporting LICs and highlighted their vulnerabilities due to the limited extent of economic diversification. Furthermore, LICs are currently facing a crisis like no other—COVID-19, which requires careful policymaking to save lives and livelihoods in LICs, informed by policy debate and thoughtful research tailored to the COVID-19 situation. There are also other challenges beyond COVID-19, such as climate change, high levels of public debt burdens, and persistent structural issues.

Would better state institutions increase tax collection, or would higher tax collection help improve state institutions? In the absence of conclusive guidance from theory, this paper searches for an empirical answer to this question, using a panel dataset covering 110 non-resource-rich countries from 1996 to 2017. Employing a panel vector error correction model, the paper finds that tax capacity and state institutions cause and reinforce each other for a wide range of country groups. The bi-directional causality results suggest that developing tax capacity and building state institutions need to go hand in hand for best results, particularly in developing countries. Based on the impulse response analyses, the paper also finds that the causal effects in advanced economies are generally low in both directions, while in developing countries, both tax capacity and institutions shocks have larger positive impacts on institutions and tax capacity, respectively.

Since its first edition in 2010, the OECD Development Centre's Perspectives on Global Development report has tracked development trends and policy priorities in developing countries. This new report examines the phenomenon of discontent. Between the global financial crisis and the COVID-19 pandemic, discontent surged around the world.

High persistence of state fragility (a fragility trap) suggests the presence of substantial benefits from avoiding a fall into fragility and considerable hurdles to successful exit from fragility. This paper empirically examines the factors that affect the turning points of entering and exiting from state fragility by employing three different approaches: an event study, the synthetic control method, and a logit model. We find that avoiding economic contraction is critical to prevent a country on the brink of fragility from falling into fragility (e.g., among near fragile countries, the probability of entering fragility would rise by 40 percentage points should real GDP per capita growth decline from +2.5 percent to -2.5 percent). Also, strengthening government effectiveness together with increasing political inclusion and maintaining robust economic activity should help make exit from fragility more successful and sustainable. In the current environment (the COVID-19 crisis and its aftermath), the findings suggest the importance of providing well-directed fiscal stimulus with sufficient financing, (subject to appropriate governance safeguards and well-designed policies), and protecting critical socio-economic spending to keep vulnerable countries away from being caught in a fragility trap.
