Abstract
This paper quantifies global demand, supply, and uncertainty shocks and compares two major global recessions: the 2008–09 Great Recession and the COVID-19 pandemic. Two alternative approaches are used to decompose economic shocks: text mining techniques on earning call transcripts and a structural Bayesian vector autoregression model. The results highlight sharp contrast in the size of supply and demand shocks over time and across sectors. While the Great Recession was characterized by demand shocks, COVID-19 caused sizable disruptions to both demand and supply. These shocks were broad-based with varying relative importance across major sectors. Furthermore, certain sub-sectors, such as professional and business services, internet retail, and grocery/department stores, fared better than others during the pandemic. The results imply that both targeted policies and conventional countercyclical fiscal and monetary policy can accelerate the economic recovery. Large demand shocks highlight an environment of deficient demand with countercyclical policy calibrated to the size of these shocks.

Publication Intergenerational Income Mobility around the World(Washington, DC: World Bank, 2025-07-09)This paper introduces a new global database with estimates of intergenerational income mobility for 87 countries, covering 84 percent of the world’s population. This marks a notable expansion of the cross-country evidence base on income mobility, particularly among low- and middle-income countries. The estimates indicate that the negative association between income mobility and inequality (known as the Great Gatsby Curve) continues to hold across this wider range of countries. The database also reveals a positive association between income mobility and national income per capita, suggesting that countries achieve higher levels of intergenerational mobility as they grow richer.Publication The Future of Poverty(Washington, DC: World Bank, 2025-07-15)Climate change is increasingly acknowledged as a critical issue with far-reaching socioeconomic implications that extend well beyond environmental concerns. Among the most pressing challenges is its impact on global poverty. This paper projects the potential impacts of unmitigated climate change on global poverty rates between 2023 and 2050. Building on a study that provided a detailed analysis of how temperature changes affect economic productivity, this paper integrates those findings with binned data from 217 countries, sourced from the World Bank’s Poverty and Inequality Platform. By simulating poverty rates and the number of poor under two climate change scenarios, the paper uncovers some alarming trends. One of the primary findings is that the number of people living in extreme poverty worldwide could be nearly doubled due to climate change. In all scenarios, Sub-Saharan Africa is projected to bear the brunt, contributing the largest number of poor people, with estimates ranging between 40.5 million and 73.5 million by 2050. Another significant finding is the disproportionate impact of inequality on poverty. Even small increases in inequality can lead to substantial rises in poverty levels. For instance, if every country’s Gini coefficient increases by just 1 percent between 2022 and 2050, an additional 8.8 million people could be pushed below the international poverty line by 2050. In a more extreme scenario, where every country’s Gini coefficient increases by 10 percent between 2022 and 2050, the number of people falling into poverty could rise by an additional 148.8 million relative to the baseline scenario. These findings underscore the urgent need for comprehensive climate policies that not only mitigate environmental impacts but also address socioeconomic vulnerabilities.Publication Engineering Ukraine’s Wirtschaftswunder(Washington, DC: World Bank, 2025-07-29)As Ukraine emerges from the devastation of war, it faces a historic opportunity to engineer its own Wirtschaftswunder—a productivity-driven economic transformation akin to post-war West Germany. While investment-led growth may offer quick wins, it is efficiency, innovation, and institutional reform that will determine Ukraine’s long-term economic trajectory. Drawing on rich micro-level firm data spanning 25 years, this paper uncovers deep structural distortions that have suppressed creative destruction and productivity in Ukraine. It finds that business dynamism is on the decline, alongside rising market concentration among incumbent businesses, including low productivity state owned enterprises. To inform priorities for reviving business dynamism, this study develops a model of creative destruction drawing on Acemoglu et al. (2018) and Akcigit et al. (2021). The quantitative assessment highlights that policies that discipline entrenched incumbents are the bedrock for reviving business dynamism and engineer Ukraine’s Wirtschaftswunder. Policies targeting specific types of firms have limited efficacy when incumbents run wild.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 Disentangling the Key Economic Channels through Which Infrastructure Affects Jobs(Washington, DC: World Bank, 2025-04-03)This paper takes stock of the literature on infrastructure and jobs published since the early 2000s, using a conceptual framework to identify the key channels through which different types of infrastructure impact jobs. Where relevant, it highlights the different approaches and findings in the cases of energy, digital, and transport infrastructure. Overall, the literature review provides strong evidence of infrastructure’s positive impact on employment, particularly for women. In the case of electricity, this impact arises from freeing time that would otherwise be spent on household tasks. Similarly, digital infrastructure, particularly mobile phone coverage, has demonstrated positive labor market effects, often driven by private sector investments rather than large public expenditures, which are typically required for other large-scale infrastructure projects. The evidence on structural transformation is also positive, with some notable exceptions, such as studies that find no significant impact on structural transformation in rural India in the cases of electricity and roads. Even with better market connections, remote areas may continue to lack economic opportunities, due to the absence of agglomeration economies and complementary inputs such as human capital. Accordingly, reducing transport costs alone may not be sufficient to drive economic transformation in rural areas. The spatial dimension of transformation is particularly relevant for transport, both internationally—by enhancing trade integration—and within countries, where economic development tends to drive firms and jobs toward urban centers, benefitting from economies scale and network effects. Turning to organizational transformation, evidence on skill bias in developing countries is more mixed than in developed countries and may vary considerably by context. Further research, especially on the possible reasons explaining the differences between developed and developing economies, is needed.

Publication Demand and Supply Dynamics in East Asia During the COVID-19 Recession(World Bank, Malaysia, 2021-05-24)The COVID-19 (coronavirus) pandemic has devastated lives and damaged economies, requiring strong and decisive policy responses from governments. Developing the optimal short-term and long-term policy response to the pandemic requires understanding the demand and supply factors that drive economic growth. The appropriate policy response will depend on the size and duration of demand and supply shocks. This Research & Policy Brief provides a decomposition of demand and supply dynamics at the macroeconomic level for the large developing economies of East Asia. The findings suggest that both demand and supply shocks were important drivers of output fluctuations during the first year of the pandemic. The demand shocks created an environment of deficient demand - reflected in large negative output gaps even after the unprecedented policy response - which is expected to last through 2021. The extant deficient demand is suggestive of continued need to support the economic recovery. Its size should guide policy makers in calibrating responses to ensure that recovery is entrenched, and that short-term supply disruptions do not lead to long-term declines in potential growth.Publication Innocent Bystanders : How Foreign Uncertainty Shocks Harm Exporters(World Bank, Washington, DC, 2012-10)The failure of trade economists to anticipate the extreme drop in trade post Lehman Brothers bankruptcy suggests that the behavior of trade in exceptional circumstances may still be poorly understood. This paper explores whether uncertainty shocks have explanatory power for movements in trade. VAR estimations on United States data suggest that domestic uncertainty is a strong predictor of movements in imports, but has little effect on exports. Guided by these results, the paper estimates a bilateral model with focus on the impact of importer uncertainty on foreign suppliers. It finds that there is a strong negative relationship between uncertainty and trade and that this relationship is non-linear. Uncertainty matters most when its levels are exceptionally high. The paper does not find evidence of learning from past turmoils, suggesting that prior experience with major uncertainty shocks does not reduce the effect on trade. In line with the expectations, the negative effect of uncertainty shocks on trade is higher for trade relationships more intensive in durable goods. Surprisingly, however, the effect of durability is non-linear. Supply chain considerations or the possibility that the relationships with the highest durability lead to important compositional effects may have a bearing on the results. The results are robust to excluding the post Lehman shock, suggesting that the trade response during the 2008-2009 crisis has been similar to past uncertainty events.Publication Determinants of Social Distancing and Economic Activity during COVID-19(World Bank, Washington, DC, 2020-05)The paper uses Google mobility data to identify the determinants of social distancing during the 2020 COVID-19 outbreak. The findings for the United States indicate that much of the decrease in mobility is voluntary, driven by the number of COVID-19 cases and proxying for greater awareness of risk. Non-pharmaceutical interventions such as closing nonessential businesses, sheltering in place, and school closings are also effective, although with a total contribution dwarfed by the voluntary actions. This suggests that much social distancing will happen regardless of the presence of non-pharmaceutical interventions and that restrictions may often function more like a coordinating device among increasingly predisposed individuals than repressive measures per se. These results are consistent across country income groups, with only the poorest countries showing limited effect of non-pharmaceutical interventions and no voluntary component, consistent with resistance to abandon sources of livelihood. The paper also confirms the direct impact of the voluntary component on economic activity, by showing that the majority of the fall in restaurant reservations in the United States and movie spending in Sweden occurred before the imposition of any non-pharmaceutical interventions. Widespread voluntary de-mobilization implies that releasing constraints may not yield a V-shaped recovery if the reduction in COVID risk is not credible.Publication How Do Rising U.S. Interest Rates Affect Emerging and Developing Economies? It Depends(World Bank, Washington, DC, 2022-12)This paper examines the implications of different types of interest rate shocks in the United States for emerging market and developing economies (EMDEs). It first classifies changes in U.S. interest rates into those caused by changes in inflation expectations (“inflation” shocks), changes in perceptions of the Federal Reserve’s reaction function (“reaction” shocks), and changes in real activity (“real” shocks). The analysis attributes this year’s sharp increases in U.S. interest rates almost exclusively to inflation and reaction shocks. These types of shocks are found to be associated with especially adverse effects: EMDE financial conditions tighten, consumption and investment fall, and governments cut spending to improve budget balances. By comparison, rising U.S. interest rates stemming from real shocks are not only associated with benign outcomes for EMDE financial conditions but also improvements in budget balances that reflect higher revenues as well as lower expenditures. Finally, this paper documents that rising U.S. interest rates driven by reaction shocks are especially likely to push EMDEs into financial crisis.Publication Policy Uncertainty and Aggregate Fluctuations(Washington, DC: World Bank, 2023-09-12)This paper identifies two types of policy uncertainty measures–government spending and real interest rates–and their impact on macroeconomic activity in 54 advanced, emerging, and developing economies. Policy uncertainty is defined as the inability to predict policy moves, that is, the conditional volatility of policy shocks. This is achieved in a panel vector autoregression model which allows, but does not require, the stochastic volatility of identified shocks to have direct and dynamic effects on macroeconomic outcomes. It shows that fiscal and monetary policy uncertainty are damaging to economic activity and act like negative supply shocks: raising prices while lowering output, investment and consumption. A one standard deviation government spending uncertainty shock decreases real gross domestic product (GDP) by a cumulative 1.0 percentage point and marginally increases inflation after two years. A one standard deviation real interest rate uncertainty shock lowers real GDP by a cumulative 1.3 percentage points after two years but raises inflation by 0.5 percentage point.

Publication Tanzania Diagnostic Review of Consumer Protection and Financial Literacy(World Bank, Washington, DC, 2013-11)In 2011, only 17.3 percemt of adults in Tanzania had an account at a formal financial institution and 56 percemt did not have any access to financial services. Most of the population lives in rural areas with very low incomes and poor infrastructure, and women are especially disadvantaged. Such limited access to formal financial services also inhibits financial literacy – awareness of benefits and risks, and how to take advantage of opportunities. Despite significant challenges, all institutional elements of the formal financial sector in Tanzania are in place, helping its gradual expansion, and in some segments technology is driving rapid growth – particularly in mobile and electronic payments. Still, gaps and weaknesses in financial consumer protection and financial education remain some of the main obstacles to sustainability and greater trust in the financial sector. This Diagnostic Review was requested by the Ministry of Finance of Tanzania in November 2012. It provides a detailed assessment of Tanzania’s institutional, legal and regulatory framework against the World Bank’s Good Practices for Financial Consumer Protection. Three segments of the financial sector have been analyzed: banking, microfinance, and pensions. Insurance and securities segments will be considered at a later stage. Volume I of the Review summarizes the key findings and recommendations and Volume II presents a detailed assessment of each financial segment compared to the Good Practices.Publication World Development Report 2017(Washington, DC: World Bank, 2017-01-30)Why are carefully designed, sensible policies too often not adopted or implemented? When they are, why do they often fail to generate development outcomes such as security, growth, and equity? And why do some bad policies endure? This book addresses these fundamental questions, which are at the heart of development. Policy making and policy implementation do not occur in a vacuum. Rather, they take place in complex political and social settings, in which individuals and groups with unequal power interact within changing rules as they pursue conflicting interests. The process of these interactions is what this Report calls governance, and the space in which these interactions take place, the policy arena. The capacity of actors to commit and their willingness to cooperate and coordinate to achieve socially desirable goals are what matter for effectiveness. However, who bargains, who is excluded, and what barriers block entry to the policy arena determine the selection and implementation of policies and, consequently, their impact on development outcomes. Exclusion, capture, and clientelism are manifestations of power asymmetries that lead to failures to achieve security, growth, and equity. The distribution of power in society is partly determined by history. Yet, there is room for positive change. This Report reveals that governance can mitigate, even overcome, power asymmetries to bring about more effective policy interventions that achieve sustainable improvements in security, growth, and equity. This happens by shifting the incentives of those with power, reshaping their preferences in favor of good outcomes, and taking into account the interests of previously excluded participants. These changes can come about through bargains among elites and greater citizen engagement, as well as by international actors supporting rules that strengthen coalitions for reform.Publication World Development Report 1984(New York: Oxford University Press, 1984)Long-term needs and sustained effort are underlying themes in this year's report. As with most of its predecessors, it is divided into two parts. The first looks at economic performance, past and prospective. The second part is this year devoted to population - the causes and consequences of rapid population growth, its link to development, why it has slowed down in some developing countries. The two parts mirror each other: economic policy and performance in the next decade will matter for population growth in the developing countries for several decades beyond. Population policy and change in the rest of this century will set the terms for the whole of development strategy in the next. In both cases, policy changes will not yield immediate benefits, but delay will reduce the room for maneuver that policy makers will have in years to come.Publication Ten Steps to a Results-Based Monitoring and Evaluation System : A Handbook for Development Practitioners(Washington, DC: World Bank, 2004)An effective state is essential to achieving socio-economic and sustainable development. With the advent of globalization, there are growing pressures on governments and organizations around the world to be more responsive to the demands of internal and external stakeholders for good governance, accountability and transparency, greater development effectiveness, and delivery of tangible results. Governments, parliaments, citizens, the private sector, Non-governmental Organizations (NGOs), civil society, international organizations, and donors are among the stakeholders interested in better performance. As demands for greater accountability and real results have increased, there is an attendant need for enhanced results-based monitoring and evaluation of policies, programs, and projects. This handbook provides a comprehensive ten-step model that will help guide development practitioners through the process of designing and building a results-based monitoring and evaluation system. These steps begin with a 'readiness assessment' and take the practitioner through the design, management, and importantly, the sustainability of such systems. The handbook describes each step in detail, the tasks needed to complete each one, and the tools available to help along the way.Publication Africa's Future, Africa's Challenge : Early Childhood Care and Development in Sub-Saharan Africa(Washington, DC : World Bank, 2008)This book seeks to achieve a balance, describing challenges that are being faced as well as developments that are underway. It seeks a balance in terms of the voices heard, including not just voices of the North commenting on the South, but voices from the South, and in concert with the North. It seeks to provide the voices of specialists and generalists, of those from international and local organizations, from academia and the field. It seeks a diversity of views and values. Such diversity and complexity are the reality of Sub-Saharan Africa (SSA) today. The major focus of this book is on SSA from the Sahel south. Approximately 130 million children between birth and age 6 live in SSA. Every year 27 million children are born, and every year 4.7 million children under age 5 die. Rates of birth and of child deaths are consistently higher in SSA than in any other part of the world; the under-5 mortality rate of 163 per 1,000 is twice that of the rest of the developing world and 30 times that of industrialized countries (UNICEF 2006). Of the children who are born, 65 percent will experience poverty, 14 million will be orphans affected by HIV/AIDS directly and within their families and one-third will experience exclusion because of their gender or ethnicity.
