Abstract
Middle-income countries host the majority of the world’s population exposed to unhealthy levels of air pollution, and the majority of this population lives in urban environments. This study investigates the impact of information provision on household behavior in connection with indoor and outdoor air pollution in a middle-income country’s major urban center — Tbilisi, Georgia. The study implemented a randomized controlled trial to assess whether providing households with different levels of pollution information changes their knowledge of air pollution and avoidance behavior with respect to air pollution, and improves their health outcomes. The study evaluates three treatments: a pamphlet with general information on pollution, the pamphlet combined with daily text messages about local outdoor pollution, and the pamphlet with messages about both indoor and outdoor pollution levels, supplemented with an indoor air pollution monitor. The findings show that while the pamphlet alone did not lead to behavioral change, daily text messages significantly enhanced knowledge about pollution, led to increased avoidance behaviors, and improved health outcomes. The study also examined infiltration rates throughout the city and document three facts: indoor air pollution levels are generally higher than outdoor ones, infiltration rates are high on average, and their variation is driven primarily by behaviors.

    The Macroeconomic Implications of Climate Change Impacts and Adaptation Options
    (Washington, DC: World Bank, 2025-05-29) Abalo, Kodzovi; Boehlert, Brent; Bui, Thanh; Burns, Andrew; Castillo, Diego; Chewpreecha, Unnada; Haider, Alexander; Hallegatte, Stephane; Jooste, Charl; McIsaac, Florent; Ruberl, Heather; Smet, Kim; Strzepek, Ken
    Estimating the macroeconomic implications of climate change impacts and adaptation options is a topic of intense research. This paper presents a framework in the World Bank's macrostructural model to assess climate-related damages. This approach has been used in many Country Climate and Development Reports, a World Bank diagnostic that identifies priorities to ensure continued development in spite of climate change and climate policy objectives. The methodology captures a set of impact channels through which climate change affects the economy by (1) connecting a set of biophysical models to the macroeconomic model and (2) exploring a set of development and climate scenarios. The paper summarizes the results for five countries, highlighting the sources and magnitudes of their vulnerability --- with estimated gross domestic product losses in 2050 exceeding 10 percent of gross domestic product in some countries and scenarios, although only a small set of impact channels is included. The paper also presents estimates of the macroeconomic gains from sector-level adaptation interventions, considering their upfront costs and avoided climate impacts and finding significant net gross domestic product gains from adaptation opportunities identified in the Country Climate and Development Reports. Finally, the paper discusses the limits of current modeling approaches, and their complementarity with empirical approaches based on historical data series. The integrated modeling approach proposed in this paper can inform policymakers as they make proactive decisions on climate change adaptation and resilience.

    From Patriarchy to Policy
    (Washington, DC: World Bank, 2025-05-29) Bussolo, Maurizio; Rexer, Jonah M.; Hu, Lynn
    Legal institutions play an important role in shaping gender equality in economic domains, from inheritance to labor markets. But where do gender equal laws come from? Using cross-country data on social norms and legal equality, this paper investigates the socio-cultural roots of gender inequity in the legal system and its implications for female labor force participation. To identify the impact of social norms, the analysis uses an empirical strategy that exploits pre-modern differences in ancestral patriarchal culture as an instrument for present-day gender norms. The findings show that ancestral patriarchal culture is a strong predictor of contemporary norms, and conservative social norms are associated with more gender inequality in the de jure legal framework, the de facto implementation of laws, and the labor market. The paper presents evidence for a political selection mechanism linking norms to laws: countries with more conservative norms elect political leaders who are more hostile to gender equality, who then pass less progressive legislation. The results highlight the cultural roots and political drivers of legalized gender inequality.

    Geopolitics and the World Trading System
    (Washington, DC: World Bank, 2024-12-23) Mattoo, Aaditya; Ruta, Michele; Staiger, Robert W.
    Until the beginning of this century, the GATT/WTO system worked. Economic research provided a compelling explanation. It showed that if governments maximize the well-being of their own countries broadly defined, GATT/WTO principles would facilitate mutually beneficial cooperation over their trade policy choices. Now heightened geopolitical rivalry seems to have undermined the WTO. A simple transposition of the previous rationalization suggests that geopolitics and trade cooperation are not compatible. The paper shows that this is only true if rivalry eclipses any consideration of own-country well-being. In all other circumstances, there are gains from trade cooperation even with geopolitics. Furthermore, the WTO’s relevance is in question only if it adheres too rigidly to its existing rules and norms. Through measured adaptation to the geopolitical imperative, the WTO can continue to thrive as a forum for multilateral trade cooperation in the age of geopolitics.

    Rethinking Fiscal Policies
    (Washington, DC: World Bank, 2025-05-27) Fuchs Tarlovsky, Alan; Amjad, Beenish; Loayza Grisi, Mario Julian
    This paper examines the redistributive impact of fiscal policy—specifically taxes and transfers—on poverty and inequality in eight countries in the Middle East and North Africa: the Arab Republic of Egypt, Djibouti, the Islamic Republic of Iran, Iraq, Jordan, Morocco, Tunisia, and the West Bank and Gaza. Utilizing the Commitment to Equity framework, the analysis evaluates how fiscal interventions alter income distribution across these diverse national contexts. The results indicate that direct cash transfers and social assistance programs are generally effective in reducing poverty and shielding vulnerable populations, while in-kind benefits—particularly in education and healthcare—significantly contribute to mitigating income inequality. In contrast, generalized subsidies, especially in the energy sector, are fiscally burdensome and largely regressive, offering limited equity gains. Indirect taxes, although important for revenue generation, often exacerbate income disparities. The study underscores the need for comprehensive fiscal reforms, including the expansion of well-targeted transfers, adoption of progressive taxation, and reallocation of inefficient subsidies toward investments in human capital. Successful initiatives, such as Egypt’s Takaful and Karama and Jordan’s Takaful and bread subsidy compensation programs, illustrate scalable models of effective redistribution. Moreover, the Islamic Republic of Iran’s progressive tax policies highlight viable pathways to equitable revenue mobilization. Strengthening investment in education and health is essential for promoting long-term equity, enhancing upward mobility, and supporting inclusive and sustainable development across the region.

    Yield Gains from Balancing Fertilizer Use
    (Washington, DC: World Bank, 2025-05-29) Arteaga, Julian; Deininger, Klaus
    As with most agricultural inputs, the optimal use of fertilizer leverages the production complementarities between different types of nutrients. Wide variation in the intensity of nutrient application rates suggests there are potentially large productivity gains to be had from rebalancing fertilizer use across nutrient types even under a fixed expenditure budget. Using detailed information on a large sample of rice fields across three states in eastern India, this paper investigates whether a more balanced use of fertilizer—measured as the ratio of potash to nitrogen applied to a field—can lead to higher yields and revenues. To address the endogeneity of fertilizer application decisions, the analysis exploits the fact that nitrogen-based fertilizers demanded by Indian farmers are mostly produced domestically in a limited number of manufacturing plants, while all potash-based fertilizers must be imported by ship from abroad. Instrumenting for the ratio of potassium-to-nitrogen fertilizer applied on a field with the relative travel distances between farmers’ villages and both the nearest urea production plant and the nearest international port, the paper estimates the impact of more balanced fertilizer use on yields and revenues. The estimates show that at median levels of fertilizer use, and keeping the level of expenditure on fertilizers constant, rebalancing fertilizer application choices such that the potassium-to-nitrogen ratio of fertilizer is doubled would lead to a 4.8 percent increase in yield.

    Impacts and Sources of Air Pollution in Tbilisi, Georgia
    (World Bank, Washington, DC, 2023-12-20) Baquie, Sandra; Behrer, Patrick A.; Du, Xinming; Fuchs, Alan; Nozaki, Natsuko K.
    Air pollution profoundly impacts welfare, causing more deaths globally than malnutrition, AIDS, tuberculosis, and malaria combined. In the Georgian capital, Tbilisi, air pollution levels exceed international standards and surpass levels in other cities in the region. The average monthly PM2.5 concentration in Tbilisi is 20 µg/m3, four times higher than the World Health Organization’s annual recommended limit. This paper uses multiple data sources — administrative data, satellite imagery, private real estate transactions, and traffic data — to estimate the impact of air pollution on the health and productivity of people in Tbilisi. It estimates that a 1 percent increase in PM2.5 levels corresponds to a 0.24 percent increase in respiratory hospitalization rates. A 1 percent increase in PM2.5 is also associated with a 0.2 percent decrease in rental prices. All the estimates are lower bounds of the total impact of air pollution as they only account for short-term consequences. The study shows that traffic and industrial activity are significant drivers of air pollution in Tbilisi. The paper also estimates the positive co-benefits of potential carbon pricing policies from air pollution reduction. Adopting a carbon tax of $25 per ton would reduce hospitalizations by 0.44 percent per district by 2036, while increasing rental prices by 0.38 percent.

    Distributional Impacts of Taxes and Benefits in Post-Soviet Countries
    (World Bank, Washington, DC, 2021-10) Fuchs, Alan; Matytsin, Mikhail; Nozaki, Natsuko Kiso; Popova, Daria
    This study compares the distributional impacts of the main tax and social spending programs in eight countries of the former Soviet Union (Armenia, Belarus, Georgia, Kyrgyzstan, Moldova, the Russian Federation, Tajikistan, and Ukraine) by applying a state-of-the-art fiscal incidence analysis based on the Commitment to Equity methodology. The region is highly interesting due to a unique combination of strong elements of path dependency (socialist legacies) with radical liberalization and welfare state retrenchment. The study examines the actual outcomes in terms of inequality and poverty and assesses the extent to which these outcomes can be attributed to various welfare state policies in these countries. It examines the extent to which taxes and social spending are progressive (whether the average transfer declines with income) and equalizing (whether they reduce inequality). In contrast to the majority of fiscal incidence studies, which are typically limited to the assessment of the impact of direct taxes and transfers, the study estimates the cumulative impact of the tax-benefit system as a whole, including direct and indirect taxes, cash transfers, and transfers in kind such as public education and health care.

    Georgia Indebtedness Poverty Note
    (World Bank, Washington, DC, 2018-11-05) Nozaki, Natsuko Kiso; Fuchs Tarlovsky, Alan; Cancho, Cesar A.
    There is considerable public concern about the level of household indebtedness in Georgia. The new regulation expected to come into force on November 1, 2018 addresses this concern by enforcing the responsible credit framework targeting commercial banks. The objective of this note is twofold. First, the note presents micro-level evidence using the nationally representative household survey to understand households’ borrowing patterns with supporting evidence from perceptions surveys. Second, the note examines plausible causal effects of over-indebtedness on household’s welfare. This paper is structured as follows. Section 2 provides macroeconomic indicators and findings from perception survey as the background evidence. Section 3 illustrates the prevalence of borrowing among the households and identifies type of households that borrow from different sources. Section 4 shows results from the causal impact analysis of bank loans on household welfare. Section 5 concludes with directions for future research.

    Climate Risk and Poverty in the Middle East and North Africa
    (Washington, DC: World Bank, 2025-03-26) Balasubramanian, Chitra; Baquie, Sandra; Fuchs, Alan
    The Middle East and North Africa faces significant climate challenges, such as increasing temperatures, heightened flood risks, frequent droughts, and growing air pollution issues. These challenges are compounded by the large proportion of the population living below the poverty line in some countries in the region. Indeed, people living in poverty are more exposed to poor air quality and natural disasters as they disproportionately tend to live in hazard-prone areas. They are also more vulnerable as they may have scarcer resources to cope with shocks. This paper combines remote sensing, geospatial data, and household surveys to provide high-resolution assessments of the exposure and vulnerability of the region’s population and poor people to four types of climate shocks. With the data available, the paper estimates that almost the entirety of the extreme poor population is exposed to at least one climate shock. The region hosts climate-poverty hot spots in the Republic of Yemen and Morocco, where adaptation to climate change will be crucial to end poverty. The resulting high-resolution estimates of exposure and vulnerability can inform the targeting of climate adaptation measures.

    Global Economic Prospects, January 2025
    (Washington, DC: World Bank, 2025-01-16) World Bank
    Global growth is expected to hold steady at 2.7 percent in 2025-26. However, the global economy appears to be settling at a low growth rate that will be insufficient to foster sustained economic development—with the possibility of further headwinds from heightened policy uncertainty and adverse trade policy shifts, geopolitical tensions, persistent inflation, and climate-related natural disasters. Against this backdrop, emerging market and developing economies are set to enter the second quarter of the twenty-first century with per capita incomes on a trajectory that implies substantially slower catch-up toward advanced-economy living standards than they previously experienced. Without course corrections, most low-income countries are unlikely to graduate to middle-income status by the middle of the century. Policy action at both global and national levels is needed to foster a more favorable external environment, enhance macroeconomic stability, reduce structural constraints, address the effects of climate change, and thus accelerate long-term growth and development.

    World Development Report 2024
    (Washington, DC: World Bank, 2024-08-01) World Bank
    Middle-income countries are in a race against time. Many of them have done well since the 1990s to escape low-income levels and eradicate extreme poverty, leading to the perception that the last three decades have been great for development. But the ambition of the more than 100 economies with incomes per capita between US$1,100 and US$14,000 is to reach high-income status within the next generation. When assessed against this goal, their record is discouraging. Since the 1970s, income per capita in the median middle-income country has stagnated at less than a tenth of the US level. With aging populations, growing protectionism, and escalating pressures to speed up the energy transition, today’s middle-income economies face ever more daunting odds. To become advanced economies despite the growing headwinds, they will have to make miracles. Drawing on the development experience and advances in economic analysis since the 1950s, World Development Report 2024 identifies pathways for developing economies to avoid the “middle-income trap.” It points to the need for not one but two transitions for those at the middle-income level: the first from investment to infusion and the second from infusion to innovation. Governments in lower-middle-income countries must drop the habit of repeating the same investment-driven strategies and work instead to infuse modern technologies and successful business processes from around the world into their economies. This requires reshaping large swaths of those economies into globally competitive suppliers of goods and services. Upper-middle-income countries that have mastered infusion can accelerate the shift to innovation—not just borrowing ideas from the global frontiers of technology but also beginning to push the frontiers outward. This requires restructuring enterprise, work, and energy use once again, with an even greater emphasis on economic freedom, social mobility, and political contestability. Neither transition is automatic. The handful of economies that made speedy transitions from middle- to high-income status have encouraged enterprise by disciplining powerful incumbents, developed talent by rewarding merit, and capitalized on crises to alter policies and institutions that no longer suit the purposes they were once designed to serve. Today’s middle-income countries will have to do the same.

    South Asia Development Update, April 2025: Taxing Times
    (Washington, DC: World Bank, 2025-04-23) World Bank
    Growth prospects for South Asia have dimmed. The global economic environment has become more challenging and is a source of heightened downside risks. After a decade of repeated disruptions, South Asia’s buffers to cushion new shocks are slim. Tackling some of its greatest inefficiencies and vulnerabilities could help South Asia navigate this unusually uncertain outlook: unproductive agricultural sectors, dependence on energy imports, pressures from rising global temperatures, and fragile fiscal positions. For most South Asian countries, increased revenue mobilization is a prerequisite for strengthening fiscal positions. Even taking into account the particular challenges of collecting taxes in South Asian economies—such as widespread informal economic activity and large agriculture sectors—South Asian economies face larger tax gaps than the average emerging market and developing economy (EMDE). This suggests the need for improved tax policy and administration. Until fiscal positions have strengthened, the burden of climate adaptation will disproportionately fall on the private sector. If allowed sufficient flexibility, private sector adaptation could offset about one-third of the likely climate damage by 2050. This may, however, require governments to remove obstacles that prevent workers and firms from moving across locations and activities. As growth prospects dim, the challenge grows to create jobs for South Asia’s rapidly expanding working-age population. South Asia’s large diasporas could become a source of strength if their knowledge, networks, and other resources can be better tapped for investment and trade.
