Abstract:
According to the Kuznets hypothesis, inequality first tends to increase and then decrease as a country develops. Whether borne out empirically, this inverted-U Kuznets curve, as a stylized ‘fact’, has shaped the discourse on economic development and income inequality for decades. In this paper we investigate whether a similar relationship holds between national income per capita and inequality of opportunity: the inequality associated with inherited individual circumstances such as gender, ethnicity, and family background. As, empirically, inequality of opportunity is positively correlated with income inequality (a relationship known as the ‘Great Gatsby’ curve), the relationship between inequality of opportunity and ‘development’ is expected to display the same inverted-U shape. We suggest that the existence of a Kuznets inequality of opportunity curve can be the result of a ‘triangular’ relationship between development, income inequality, and inequality of opportunity. We propose a simple theoretical model that links the three concepts and describes two possible mechanisms. A numerical simulation based on the model illustrates the process. We then draw on the newly published Global Estimates of Opportunity and Mobility database to shed new light on this ‘triangular’ relationship, primarily in a cross-sectional context.

Abstract:
Climate-related disasters have increased over recent decades, with severe human and economic consequences. While research has examined their macroeconomic effects and impact on households’ income and consumption patterns, little attention has been given to their impact on tax morale—taxpayers’ intrinsic motivation to comply with tax obligations. This study fills this gap by estimating the impact of climaterelated disasters on tax morale in 26 sub-Saharan African countries using Afrobarometer survey data from 2011 to 2021. The analysis considers six climate-related shocks: droughts, earthquakes, extreme temperatures, floods, storms, and wildfires. We hypothesize that the impact of climate-related disasters on tax morale depends on the specific disasters considered, and that these heterogeneous effects work through two key mechanisms: economic inequality and trust in public institutions. First, they can exacerbate inequality by reducing government revenue, increasing economic hardship for vulnerable groups (through loss of livelihoods), and eliciting unequal policy responses from government. Climate-related disasters can also reduce inequality when associated with increased economic hardship for richer households (by destroying their productive assets. Second, tax morale declines when citizens perceive government responses as inadequate or unfair; conversely, it increases if citizens perceive the government to be responding adequately. Logistic regression results confirm this heterogeneity. Droughts, extreme temperatures, floods, and storms reduce tax morale, while earthquakes and wildfires increase it. Incorporating regional heterogeneity shows that the negative effects of disasters on tax morale are more profound in rural areas. Mediation analysis confirms inequality and institutional trust as key transmission channels. These findings underscore the need for inclusive tax policies and effective post-disaster governance to sustain revenue mobilization in sub-Saharan Africa.

Abstract:
This paper provides the first comprehensive analysis of how firms in emerging economies respond to carbon taxation, leveraging detailed administrative data from South Africa—a potential trailblazer for other developing countries with limited state capacity amid the growing global push for carbon pricing. We examine the dynamic impacts of the carbon tax on firm-level outcomes—such as profits, sales, capital, and labour inputs—across manufacturing and mining firms, which are key sectors in the context of the carbon tax. Contrary to concerns that carbon taxes may hinder economic growth or reduce employment, our findings show no evidence of negative average impacts on firm performance or jobs. However, this overall result masks significant heterogeneity in the tax’s effects across sectors, driven by the sector-specific design elements of the South African carbon tax. Firms expecting higher effective tax rates may have intensified their use of emission-intensive machinery and depreciated capital in anticipation of the tax. This behaviour appears to stem from firms resolving regulatory uncertainty or seeking to recover costs from stranded assets.

404. Rethinking development finance in Tajikistan: Towards more sustainable and inclusive fiscal pathways

Working Paper
Institution:
United Nations University
Abstract:
This paper rethinks development finance in Tajikistan through the lens of fiscal sociology, arguing that sustained reliance on foreign aid and external borrowing may weaken state-society trust and erode institutional legitimacy. Anchored in the political economy of development finance, the paper explores how alternative financing strategies, such as tax reform, diaspora bonds, thematic bonds, and blended finance, interact with domestic institutions, investor confidence, and citizen perceptions of fiscal fairness. While external flows have financed essential infrastructure and social programmes, they have also limited incentives for domestic resource mobilization and weakened public accountability. Issues of debt sustainability increasingly constrain long-term planning, while climate finance is emerging as both a challenge and an opportunity for diversifying development funding. Drawing on policy analysis and secondary data, the paper shows that financial instruments succeed not only through technical design but through their ability to reinforce the fiscal social contract. Tajikistan’s case illustrates that without improvements in governance, transparency, and citizen engagement, even well-structured innovations in development finance may fail to gain traction. The findings offer practical insights for low-income countries seeking to reduce aid dependency while building more credible and inclusive systems of public finance.

405. Twenty-five years of inflation-targeting in South Africa: Going from 6% to 3%?

Author:
Philippe Burger

Content Type:
Working Paper
Institution:
United Nations University
Abstract:
This paper proposes that the South African Reserve Bank should pursue a 3% inflation target, instead of the current 4.5% midpoint of a 3%-to-6% target range. Doing so may also result in lower inflation volatility, thereby reducing nominal exchange rate risk for investment and trade, and may thus support economic growth. Using a two-regime Markov-switching model, the analysis shows that since the global financial crisis, periods of higher inflation volatility are much shorter. Thus, inflation is relatively better anchored since the global financial crisis. But there are still shocks that coincide with periods of exchange rate volatility. Lastly, the analysis shows that the budget deficit/gross domestic product ratio, constraints on electricity supply, and administered prices contribute significantly to inflation, while the effect of real gross domestic product growth (as a demand variable) is limited. The analysis also argues that the sacrifice ratio, measuring the sacrifice of growth and employment that is required to reduce inflation, is of limited use once the potential role that other variables can play in the reduction of inflation and inflationary expectations is considered. The government has an especially significant role to play in supporting the South African Reserve Bank in lowering the inflation rate to an average of 3% by lowering the level and volatility of administered price inflation, reducing the budget deficit, and improving electricity supply.

Abstract:
The Caribbean’s geographic proximity to the United States—as well as its use as a transit point for US citizens, goods, and financial services—makes it a crucial hub for US national interests. However, the relationship has suffered from inconsistent and infrequent assistance. Changes in US policy priorities bring ever-changing adjustments to US engagement, leaving the Caribbean, its leadership, and its institutions with insufficient time to benefit from US policy action. For Caribbean countries, policy continuity is critical for implementation and to see tangible and meaningful development. The region’s small populations and markets, vulnerability to natural disasters and changing global commodity prices, and limited institutional capacity slow the pace of receiving and utilizing development assistance and support. Underpinning US-Caribbean ties with stronger US congressional engagement can provide needed longevity to the relationship. Congressional actions—like newly appropriated resources and committee hearings—can bring tangible benefits to US-Caribbean relations.

Abstract:
For more than a decade, Syria’s crisis has caused unimaginable suffering inside the country and a constant stream of strategically significant spillover effects across the Middle East and globally. However, this dynamic changed in late 2024, when armed opposition groups in Syria’s northwest launched a sudden and unprecedentedly sophisticated and disciplined offensive, capturing the city of Aleppo and triggering an implosion of Bashar al-Assad’s regime. In the space of ten days, Assad’s rule collapsed like a house of cards, dealing a crippling blow to Iran’s role in Syria and significantly weakening Russia’s influence. Now, for the first time in many years, Syria has a chance to recover and reintegrate into the international system. If the United States, Europe, Middle Eastern nations, and other stakeholders embrace the right approach, support the right policies, and encourage Syria’s transition to move in the appropriate direction, the world will benefit—and Syrians will find peace. The work of the Syria Strategy Project (SSP) and the policy recommendations in the report “Reimagining Syria: A roadmap for peace and prosperity beyond Assad” present a realistic and holistic vision for realizing that goal. This report is the result of intensive joint efforts by the Atlantic Council, the Middle East Institute (MEI), and the European Institute of Peace (EIP), which have been collaborating since March 2024 on the SSP. At its core, the project has involved a sustained process of engagement with subject-matter experts and policymakers in the United States, Europe, and across the Middle East to develop a realistic and holistic strategic vision for sustainably resolving Syria’s crisis. This process, held almost entirely behind closed doors, incorporated Syrian experts, civil society organizations, and other stakeholders at every step.

408. The European Union Growth Plan for the Western Balkans: A reality test for EU enlargement

Abstract:
The European Union (EU) Growth Plan for the Western Balkans aims to integrate the region into the EU single market, enhance regional cooperation, implement significant governance and rule of law reforms, and boost EU financial support. In doing so, the EU seeks to foster economic development, political stability, and security in the region amid rising geopolitical tensions, while accelerating the Western Balkans’ EU accession process. The Growth Plan holds substantial potential to reinvigorate the enlargement process and counter the stagnation felt by both the EU and the region. Strong points include: Tangible benefits before full accession: Providing stronger incentives for reform. Active involvement of regional governments: Increasing buy-in from local leaders, who must submit their own reform agendas. Enhanced economic integration, greater access to the EU market, increased EU funding, and reforms to governance and the rule of law: Stimulating investment, promoting economic growth, and raising living standards. These improvements would bring the Western Balkans closer to the economic success seen in the Central and Eastern European countries in the EU over the past two decades. Moreover, fostering deeper regional cooperation will not only deliver an economic boost but also contribute to political normalization. If successful, the plan will bolster the EU’s political influence in the region, countering the impact of external actors and encouraging much-needed nearshoring investment from EU firms. However, the plan faces several challenges: Enforceability: Although conditionality is rigorous, with disbursement of funds tied to strict conditions to prevent misuse, there are concerns regarding its enforceability. The European Court of Auditors has already raised reservations. Quantity: Additionally, the financial support offered is significantly lower than what EU member states in Southeast Europe receive. The reforms required for fund access and single market integration are substantial and will demand significant political will and institutional capacity—both of which have been lacking in the region at times over the past two decades. The success of the growth plan will largely depend on its implementation. The EU must ensure rigorous enforcement of conditionality, reward positive reform steps, and increase funding for countries making progress. Civil society in the Western Balkans should be engaged as much as possible to foster broader support and transparency. The EU should also leverage the plan to align with its broader geopolitical and geoeconomic interests, particularly in strengthening its strategic autonomy. Additionally, the Growth Plan should be fully integrated with the EU’s competitiveness, green, and digital transition agendas. For their part, Western Balkans leaders should seize the increased agency provided by the plan. They must take ownership of the reforms they propose, participate actively in EU meetings, and design their reform agendas to deliver better living standards and deeper EU integration for their populations.

Abstract:
Commercial fusion is on the horizon, with many experts arguing that fusion power plants could put electrons on the grid by the end of this decade. However, there are questions around the process for regulating fusion power plants. In this Atlantic Council issue brief, authors Sachin S. Desai, Michael Y. Hua, Amy C. Roma, Jessica A. Bufford, Jacqueline E. Siebens, and J. Andrew Proffitt explore pathways to address regulation, nonproliferation, and export considerations for fusion technologies. They argue that fusion power plants should be regulated in a pathway that is separate from the regulatory pathways established for fission reactors, especially since the materials and processes involved in fusion power plants are significantly different from fission reactors.

410. The imperative of augmenting US theater nuclear forces

Atlantic Council
Abstract:
The United States and its allies and partners face an impending change in the threats posed by nuclear-armed adversaries: a strategic environment marked by two nuclear peer major powers. Russia, long a nuclear peer of the United States, will likely emerge from the war in Ukraine—regardless of how it ends—even more reliant on its nuclear forces, which are already the largest in the world. Meanwhile, China is undertaking the largest nuclear force buildup since the Cold War. That buildup will increase the size of Beijing’s nuclear forces by roughly seven and a half times since 2018, positioning China as a nuclear peer of the United States by 2035.1 Meanwhile, North Korea continues to expand and diversify its nuclear arsenal. Although the North Korean threat has been somewhat constrained by the quality of its ballistic missile systems—particularly its intercontinental ballistic missiles (ICBMs)—technical assistance from Russia, in exchange for Kim Jong Un’s material support for the war in Ukraine, could rapidly enhance North Korean capabilities. Finally, the ongoing conflict in the Middle East could prompt Iran to choose to acquire its own nuclear arsenal, presenting a wholly new challenge. A pair of recent analyses of the strategic impact of this two-nuclear-peer environment have sounded an alarm, making clear that this environment poses a qualitatively and quantitatively new threat of adversary aggression and the potential for nuclear war.2 Conducted by bipartisan teams of former senior US officials and other nuclear experts, both analyses concluded—in the words of the Congressional Commission on the Strategic Posture of the United States (hereafter referred to as the Strategic Posture Commission)—that the planned US nuclear force “is absolutely essential, although not sufficient [emphasis added] to meet the new threats posed by Russia and China.”3 Both reports emphasized the urgent need to enhance US theater nuclear forces to address the most likely path to large-scale nuclear war: the failure to deter or counter limited adversary nuclear use in an ongoing conventional conflict. Finally, both reports laid out a set of attributes that US theater nuclear force enhancements must possess to effectively address the threat of limited nuclear escalation. However, these reports did not examine in depth the deterrence and warfighting implications of alternative new US theater nuclear systems. This paper examines why the two-nuclear-peer threat makes the enhancement of US theater nuclear forces an urgent imperative. It explains why the planned US strategic and theater nuclear forces are insufficient to address this threat. The paper then presents a more detailed set of political-military and operational attributes that enhanced US theater nuclear forces must possess to effectively counter the threat. Using these attributes, it evaluates the relative deterrence and warfighting value of various potential alternative theater-range nuclear weapon systems. The paper concludes with a recommended future US theater nuclear force structure and posture, specifically, that the United States should field a theater nuclear force that combines an effectively dispersible dual-capable fighter aircraft (DCA) force in Europe with nuclear-armed sea-launched cruise missile (SLCM-Ns) deployed day-to-day on attack submarines (SSNs) in Europe and Asia and ground-launched cruise missiles (GLCM-Ns) and/or ground-launched ballistic missiles (GLBM-Ns) continuously deployed in Europe and/or Asia.
