Abstract
This study documents the impacts of climate change on firm-level productivity by matching a globally comparable and standardized survey of nonagricultural firms covering 154 countries with climate data. The findings show that the overall effects of rising temperatures on productivity are negative but nonlinear and uneven across climate zones. Firms in hotter zones experience steeper losses with increases in temperature. A 1 degree Celsius increase from the typical wet-bulb temperature levels in the hottest climate zone (25.7 degrees Celsius and above) results in a productivity decline of about 20.8 percent compared to firms in the coldest climate zone. The effects vary not only based on the temperature zones within which firms are located, but also on other factors such as firm size, industry classification, income group, and region. Large firms, firms in manufacturing, and those in low-income countries and hotter climate zones tend to experience the biggest productivity losses. The uneven impacts, with firms in already hotter regions and low-income countries experiencing steeper losses in productivity, suggest that climate change is reinforcing global income inequality. If the trends in global warming are not reversed over the coming decades, there is a heightened risk of widening inequality across countries. The implications are especially dire for the poorest countries in the hottest regions.

Publication Geopolitics and the World Trading System(Washington, DC: World Bank, 2024-12-23)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.Publication The Macroeconomic Implications of Climate Change Impacts and Adaptation Options(Washington, DC: World Bank, 2025-05-29)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.Publication Global Poverty Revisited Using 2021 PPPs and New Data on Consumption(Washington, DC: World Bank, 2025-06-05)Recent improvements in survey methodologies have increased measured consumption in many low- and lower-middle-income countries that now collect a more comprehensive measure of household consumption. Faced with such methodological changes, countries have frequently revised upward their national poverty lines to make them appropriate for the new measures of consumption. This in turn affects the World Bank’s global poverty lines when they are periodically revised. The international poverty line, which is based on the typical poverty line in low-income countries, increases by around 40 percent to $3.00 when the more recent national poverty lines as well as the 2021 purchasing power parities are incorporated. The net impact of the changes in international prices, the poverty line, and new survey data (including new data for India) is an increase in global extreme poverty by some 125 million people in 2022, and a significant shift of poverty away from South Asia and toward Sub-Saharan Africa. The changes at higher poverty lines, which are more relevant to middle-income countries, are mixed.Publication Global Socio-economic Resilience to Natural Disasters(Washington, DC: World Bank, 2025-05-22)Most disaster risk assessments use damages to physical assets as their central metric, often neglecting distributional impacts and the coping and recovery capacity of affected people. To address this shortcoming, the concepts of well-being losses and socio-economic resilience—the ability to experience asset losses without a decline in well-being—have been proposed. This paper uses microsimulations to produce a global estimate of well-being losses from, and socio-economic resilience to, natural disasters, covering 132 countries. On average, each $1 in disaster-related asset losses results in well-being losses equivalent to a $2 uniform national drop in consumption, with significant variation within and across countries. The poorest income quintile within each country incurs only 9% of national asset losses but accounts for 33% of well-being losses. Compared to high-income countries, low-income countries experience 67% greater well-being losses per dollar of asset losses and require 56% more time to recover. Socio-economic resilience is uncorrelated with exposure or vulnerability to natural hazards. However, a 10 percent increase in GDP per capita is associated with a 0.9 percentage point gain in resilience, but this benefit arises indirectly—such as through higher rate of formal employment, better financial inclusion, and broader social protection coverage—rather than from higher income itself. This paper assess ten policy options and finds that socio-economic and financial interventions (such as insurance and social protection) can effectively complement asset-focused measures (e.g., construction standards) and that interventions targeting low-income populations usually have higher returns in terms of avoided well-being losses per dollar invested.Publication From Patriarchy to Policy(Washington, DC: World Bank, 2025-05-29)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.

Publication Mobile Access Expansion and Price Information Diffusion(World Bank, Washington, DC, 2021-08)This paper investigates whether enhanced access to mobile communications, including internet, primarily through smart phones, increases competition as price information is more widely available to customers—both households and firms. The exogenous shock to identify these impacts is the transition from 2G to the 3G broadband network standard in 2008, and the induced changes in the geographic variation across districts of data plan availability for households. The operational mechanism is that better household and firm telecommunications access can close information asymmetry gaps between buyers and sellers, with increased competition leading to improved firm performance. Lower markups and reduced price dispersion can result from better incentives for firms to preserve and grow market share. And as price competition squeezes profit margins, there are more incentives for firms to reduce costs—inducing higher total factor productivity growth. Improved firm performance can generate jobs and economic transformation. Indeed, faster productivity growth, due to enhanced access for buyers to mobile telecommunications, can translate into higher formal employment and wages. One open question is whether the potential competition, driven by the increased mobile telecommunications access of buyers, which help them have the best alternative prices at their fingertips, will also impact export-oriented companies. The prior is that the firm performance improvement effect would be more salient for firms mostly focused on local markets. The primary data sources are manufacturing firm census data and household expenditure survey data across woredas (districts or counties) in Ethiopia. First, the paper investigates the relation between expanded access with the 3G network to price information through mobile phones (measured at the woreda level as share of households with substantive expenditure to access data through smartphones) and firm performance measures (markups, total factor productivity, labor productivity, wage growth, wage gaps and employment growth.), across districts with different shares of mobile telecommunication and data plan penetration subscription. The paper estimates models with difference-in-differences and triple differences. The evidence is consistent with competition intensification after the improvement in access to mobile communication due to the 3G network rollout. In particular, markups were reduced and there was higher growth in productivity, wages, and employment.Publication Economic Transformation in Africa(Washington, DC: World Bank, 2024-09-09)This paper contributes to the discussion on Africa's pathways to economic transformation by examining the roles of trade patterns—specifically, South-South and North-South trade—focusing on intermediate and capital goods sourced from both the Global North and the Global South. The paper relies on a panel dataset comprising 44 African countries from 2000 to 2022. To address endogeneity concerns, it uses a two-stage least squares method, employing instrumental variables that leverage exogenous changes in trading partner conditions. Findings from the analysis indicate that imported capital and intermediates significantly predict economic transformation in Africa. However, the impact of imports from the Global North and the Global South varies depending on the specific channel of economic transformation. Imports from the Global South are more influential in driving structural change, while those from the Global North are more effective in facilitating productivity convergence. This divergence highlights the distinct roles that North-South and South-South trade play in Africa’s economic transformation agenda. The findings underscore the importance of a nuanced trade policy that leverages the strengths of both regional and global trade partners to advance Africa's economic transformation.Publication Trade Barriers or Catalysts? Non-Tariff Measures and Firm-Level Trade Margins(Washington, DC: World Bank, 2025-01-09)This paper empirically examines how standards and technical regulations affect export margins in three African countries at the firm level. The approach involves combining detailed customs transaction data at the firm-product level with bilateral information on non-tariff measures within a gravity model of trade framework. The findings show standards and technical regulations have no impact on the extensive margin of firm-level trade. However, they do diminish trade at the intensive margin in both the agriculture and manufacturing sectors. Small firms are more affected at the intensive margin compared to medium and large firms, and similarly, final goods are more affected compared to inter-mediate goods. Moreover, in the manufacturing sector, firms with initially higher product quality experience a reversal of the trade-reducing effect of standards and technical regulations, whereas in the agriculture sector, this effect is less pronounced for their counterparts. The results also suggest that African exporting firms face equivalent impacts in both regional and global markets.Publication Financial Development, Exchange Rate Regimes, and Growth Dynamics(World Bank, Washington, DC, 2018-08)This paper utilizes data for African countries to analyze the extent to which financial development affects the dynamics of the relationship between exchange rate flexibility and economic growth. The findings indicate that financial development exerts a positive influence on the relationship between exchange rate flexibility and GDP growth as well as total factor productivity growth. The paper also documents a positive impact of trade openness on the relationship between exchange rate flexibility and growth. Moreover, the results show a strong and positive association between exchange rate flexibility and financial development. The findings, therefore, suggest that discussions and decisions on exchange rate policy should be undertaken with consideration for structural policies that address the development of the financial sector. In addition, the paper asserts that policy makers should adopt a stance that facilitates some flexibility in exchange rates to foster development of the financial infrastructure in these economies.Publication Trade Creation and Trade Diversion in African RECs(World Bank, Washington, DC, 2021-08)This study aims to draw key lessons for the African Continental Free Trade Area using evidence from within the region. Although drawing lessons from the rest of the world is essential, given the unique features of economies in the Africa region, the most relevant lessons can be drawn from the experiences of regional economic communities in the continent. The study draws on the eight regional economic communities that have been recognized by the African Union as pillars on which the continent will rely to implement the African Continental Free Trade Area. The study evaluates the trade creation and trade diversion impacts of each of the eight RECs and examines their performance with the goal of drawing lessons and identifying challenges for the success of the African Continental Free Trade Area. Despite significant heterogeneities, there is more trade creation than trade diversion and a generally positive impact on trade within the regional economic communities. Two regional economic communities in particular—the East African Community and the Southern African Development Community—outperform all the other regional economic communities in terms of boosting intra–regional economic community trade. This is mainly associated with the high level of investment in trade facilitation, the level of synergy between national and regional goals, the density of economic activity, and the advancement in the quantity and quality of regional infrastructure. There are also many challenges that policy makers should address to realize the objectives of the African Continental Free Trade Area and transform the continent. Learning from the regional economic communities is central. But, given the scope of the African Continental Free Trade Area, there is also a need to examine the transition from regional economic communities to the African Continental Free Trade Area, which is expected to be a sticky transition.

Publication World Development Report 2024(Washington, DC: World Bank, 2024-08-01)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.Publication World Development Report 2023: Migrants, Refugees, and Societies(Washington, DC : World Bank, 2023-04-25)Migration is a development challenge. About 184 million people—2.3 percent of the world’s population—live outside of their country of nationality. Almost half of them are in low- and middle-income countries. But what lies ahead? As the world struggles to cope with global economic imbalances, diverging demographic trends, and climate change, migration will become a necessity in the decades to come for countries at all levels of income. If managed well, migration can be a force for prosperity and can help achieve the United Nations’ Sustainable Development Goals. World Development Report 2023 proposes an innovative approach to maximize the development impacts of cross-border movements on both destination and origin countries and on migrants and refugees themselves. The framework it offers, drawn from labor economics and international law, rests on a “Match and Motive Matrix” that focuses on two factors: how closely migrants’ skills and attributes match the needs of destination countries and what motives underlie their movements. This approach enables policy makers to distinguish between different types of movements and to design migration policies for each. International cooperation will be critical to the effective management of migration.Publication Economic Recovery(World Bank, Washington, DC, 2021-04-06)World Bank Group President David Malpass spoke about the world facing major challenges, including COVID, climate change, rising poverty and inequality and growing fragility and violence in many countries. He highlighted vaccines, working closely with Gavi, WHO, and UNICEF, the World Bank has conducted over one hundred capacity assessments, many even more before vaccines were available. The World Bank Group worked to achieve a debt service suspension initiative and increased transparency in debt contracts at developing countries. The World Bank Group is finalizing a new climate change action plan, which includes a big step up in financing, building on their record climate financing over the past two years. He noted big challenges to bring all together to achieve GRID: green, resilient, and inclusive development. Janet Yellen, U.S. Secretary of the Treasury, mentioned focusing on vulnerable people during the pandemic. Kristalina Georgieva, Managing Director of the International Monetary Fund, focused on giving everyone a fair shot during a sustainable recovery. All three commented on the importance of tackling climate change.Publication Media and Messages for Nutrition and Health(World Bank, Washington, DC, 2020-06)The Lao People’s Democratic Republic (Lao PDR) has experienced rapid and significant economic growth over the past decade. However, poor nutritional outcomes remain a concern. Rates of childhood undernutrition are particularly high in remote, rural, and upland areas. Media have the potential to play an important role in shaping health and nutrition–related behaviors and practices as well as in promoting sociocultural and economic development that might contribute to improved nutritional outcomes. This report presents the results of a media audit (MA) that was conducted to inform the development and production of mass media advocacy and communication strategies and materials with a focus on maternal and child health and nutrition that would reach the most people from the poorest communities in northern Lao PDR. Making more people aware of useful information, essential services and products and influencing them to use these effectively is the ultimate goal of mass media campaigns, and the MA measures the potential effectiveness of media efforts to reach this goal. The effectiveness of communication channels to deliver health and nutrition messages to target beneficiaries to ensure maximum reach and uptake can be viewed in terms of preferences, satisfaction, and trust. Overall, the four most accessed media channels for receiving information among communities in the study areas were village announcements, mobile phones, television, and out-of-home (OOH) media. Of the accessed media channels, the top three most preferred channels were village announcements (40 percent), television (26 percent), and mobile phones (19 percent). In terms of trust, village announcements were the most trusted source of information (64 percent), followed by mobile phones (14 percent) and television (11 percent). Hence of all the media channels, village announcements are the most preferred, have the most satisfied users, and are the most trusted source of information in study communities from four provinces in Lao PDR with some of the highest burden of childhood undernutrition.Publication Remarks at the United Nations Biodiversity Conference(World Bank, Washington, DC, 2021-10-12)World Bank Group President David Malpass discussed biodiversity and climate change being closely interlinked, with terrestrial and marine ecosystems serving as critically important carbon sinks. At the same time climate change acts as a direct driver of biodiversity and ecosystem services loss. The World Bank has financed biodiversity conservation around the world, including over 116 million hectares of Marine and Coastal Protected Areas, 10 million hectares of Terrestrial Protected Areas, and over 300 protected habitats, biological buffer zones and reserves. The COVID pandemic, biodiversity loss, climate change are all reminders of how connected we are. The recovery from this pandemic is an opportunity to put in place more effective policies, institutions, and resources to address biodiversity loss.
