Abstract
This paper studies the impact of central bank independence on sovereign borrowing, using an index that captures institutional constraints on central bank lending to the government across 155 countries from 1972 to 2023. The findings show that tighter lending to the executive significantly reduces sovereign interest rates and raises the debt-to-gross domestic product ratio in developing countries. These effects reflect the executive’s improved ability to borrow at lower costs under greater central bank independence. The results are robust to multiple tests, but there are no significant effects in advanced economies. From a policy perspective, the results highlight the key role of independent central banks as catalysts for reducing governments’ borrowing costs and enhancing the government’s borrowing capacity.

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 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 Gender Gaps in the Performance of Small Firms: Evidence from Urban Peru(Washington, DC: World Bank, 2025-09-23)This paper estimates the gender gap in the performance of firms in Peru using representative data on both formal and informal firms. On average, informal female-led firms have lower sales, labor productivity, and profits compared to their male-led counterparts, with differences more pronounced when controlling for observable determinants of firm performance. However, gender gaps are only significant at the bottom of the performance distribution of informal firms, and these gaps disappear at the top of the distribution of informal firms and for formal firms. Possible explanations for the performance gaps at the bottom of the distribution include the higher likelihood of small, female-led firms being home-based, which is linked to lower profits, and their concentration in less profitable sectors. The paper provides suggestive evidence that household responsibilities play a key role in explaining the gender gap in firm performance among informal firms. Therefore, policies that promote access to care services or foster a more equal distribution of household activities may reduce gender productivity gaps and allow for a more efficient allocation of resources.Publication The Exposure of Workers to Artificial Intelligence in Low- and Middle-Income Countries(Washington, DC: World Bank, 2025-02-05)Research on the labor market implications of artificial intelligence has focused principally on high-income countries. This paper analyzes this issue using microdata from a large set of low- and middle-income countries, applying a measure of potential artificial intelligence occupational exposure to a harmonized set of labor force surveys for 25 countries, covering a population of 3.5 billion people. The approach advances work by using harmonized microdata at the level of individual workers, which allows for a multivariate analysis of factors associated with exposure. Additionally, unlike earlier papers, the paper uses highly detailed (4 digit) occupation codes, which provide a more reliable mapping of artificial intelligence exposure to occupation. Results within countries, show that artificial intelligence exposure is higher for women, urban workers, and those with higher education. Exposure decreases by country income level, with high exposure for just 12 percent of workers in low-income countries and 15 percent of workers in lower-middle-income countries. Furthermore, lack of access to electricity limits effective exposure in low-income countries. These results suggest that for developing countries, and in particular low-income countries, the labor market impacts of artificial intelligence will be more limited than in high-income countries. While greater exposure to artificial intelligence indicates larger potential for future changes in certain occupations, it does not equate to job loss, as it could result in augmentation of worker productivity, automation of some tasks, or both.Publication Geopolitical Risks and Trade(Washington, DC: World Bank, 2025-09-23)This paper studies the impact of geopolitical risks on international trade, using the Geopolitical Risk (GPR) index of Caldara and Iacoviello (2022) and an empirical gravity model. The impact of spikes in geopolitical risk on trade is negative, strong, and heterogeneous across sectors. The findings show that increases in geopolitical risk reduce trade by about 30 to 40 percent. These effects are equivalent to an increase of global tariffs of up to 14 percent. Services trade is most vulnerable to geopolitical risks, followed by agriculture, and the impact on manufacturing trade is moderate. These negative effects are partially mitigated by cultural and geographic proximity, as well as by the presence of trade agreements.

Publication Sovereign Debt Management in Crisis in Europe and Central Asia(Washington, DC, 2013-05)The global financial crisis of 2008-2009 required most sovereign debt managers to adapt to rapidly changing market circumstances, by changing the mix of borrowing instruments and adopting techniques that minimize the impact of severe market dislocations and increased risk aversion. These actions, allied to prudent macroeconomic and debt management policies implemented by government in the years preceding the crises, were critical in helping countries meet their financing needs without undue strain on the financial markets. This toolkit draws on the approaches taken by a range of countries and provides sovereign debt policy makers with a rich set of potential actions to address crisis periods. A practical illustration on the use of some of these actions is conducted by analyzing the measures taken by Romania, Serbia and Turkey as a response to the recent crises. Authors draw lessons from these experiences and examine what other measures included in the toolkit could have been used to boost the crisis response impact in these economies, respecting country-specific contexts.Publication Bureaucratic Delegation and Political Institutions : When Are Independent Central Banks Irrelevent?(World Bank, Washington, DC, 2000-06)The government's ability to credibly commit to policy announcements is critical to the successful implementation of economic policies as diverse as capital taxation and utilities regulation. One frequently advocated means of signaling credible commitment is to delegate authority to an agency that will not have an incentive to opportunistically change policies once the private sector has taken such steps as signing wage contracts or making irreversible investments. Delegating authority is suggested as a government strategy particularly for monetary policy. And existing work on the independence of central banks generally assumes that government decisions to delegate are irrevocable . But delegation - in monetary policy as elsewhere-is inevitably a political choice, and can be reversed, contend the authors. They develop a model of monetary policy that relaxes the assumption that monetary delegation is irreversible. Among the testable predictions of the model are these: A) The presence of an independent central bank should reduce inflation only in the presence of political checks and balances. This effect should be evident in both developing and industrial countries. B) Political actions to interfere with the central bank should be more apparent when there are few checks and balances. C) The effects of checks and balances should be more marked when political decisionmakers are more polarized. The authors test these predictions and find extensive empirical evidence to support each of the observable implications of their model: Central banks are associated with better inflation outcomes in the presence of checks and balances. The turnover of central bank governors is reduced when governors have tenure protection supported by political checks and balances. And the effect of checks and balances is enhanced in more polarized political environments.Publication International Reserves and Central Bank Independence(World Bank, Washington, DC, 2021-11)This paper proposes a novel theory of reserve accumulation that emphasizes the role of an independent central bank. Motivated by a positive correlation between reserve accumulation and central bank independence in Latin America, the paper develops a quantitative sovereign default model with an independent central bank that can accumulate a risk-free foreign asset. The findings show that if the central bank is more patient than the government and as patient as households are, in equilibrium, the government issues more debt than what is socially optimal, and the central bank accumulates reserves to undo government over-borrowing. A key insight is that the government can issue more debt for any level of reserves but chooses not to because doing so would increase sovereign spreads, making it more costly to borrow. Quantitatively, the analysis finds that the central bank independence channel accounts for 75 percent of the average reserve levels observed in Mexico from 1994 to 2017. Finally, the paper shows that accumulating reserves improves social welfare. Welfare gains come from reducing the costs of front-loading public spending.Publication Banking and Regulation in Emerging Markets : The Role of External Discipline(Oxford University Press on behalf of the World Bank, 2006-08-05)This article reviews the main issues of regulating and supervising banks in emerging markets with a view toward evaluating the long-run options. Particular attention is paid to Latin America and East Asia. These economies face a severe policy commitment problem that leads to excessive bailouts and potential devaluation of claims of foreign investors. This exacerbates moral hazard and makes a case for importing external discipline (for example, acquiring foreign short-term debt). However, external discipline may come at the cost of excessive liquidation of entrepreneurial projects. The article reviews the tradeoffs imposed by external discipline and examines various arrangements, such as narrow banking, foreign banks and foreign regulation, and the potential role for an international agency or international lender of last resort.Publication European Economic and Monetary Union Sovereign Debt Markets(World Bank Group, Washington, DC, 2015-01)This paper focuses on developments in the European Economic and Monetary Union sovereign debt markets in the past decade. The first part analyzes the integration and segmentation structure of the bond markets of the Economic and Monetary Union before and after the sovereign debt crisis, by introducing the novel concept of correlation-based stable networks. Accordingly, a fair integration is observed between the bond markets during the pre-crisis period. However, a strict segmentation emerges, separating the members struggling with debt problems and the ones with relatively strong fiscal performances during the sovereign debt turmoil. The segmentation structure is clearly visualized, revealing the potential paths for crisis and recovery transmission in the future. In the second part, the paper comments on the recent decreasing trend in Economic and Monetary Union member bond yields and their increasing degree of co-movement. Accordingly, the paper argues that these changes do not depend on the fiscal performances of the member countries, but depend on the illusion of quality that appeared with the Fed (U.S. Federal Reserve) tapering signals in early 2013.

Publication Business Ready 2024(Washington, DC: World Bank, 2024-10-03)Business Ready (B-READY) is a new World Bank Group corporate flagship report that evaluates the business and investment climate worldwide. It replaces and improves upon the Doing Business project. B-READY provides a comprehensive data set and description of the factors that strengthen the private sector, not only by advancing the interests of individual firms but also by elevating the interests of workers, consumers, potential new enterprises, and the natural environment. This 2024 report introduces a new analytical framework that benchmarks economies based on three pillars: Regulatory Framework, Public Services, and Operational Efficiency. The analysis centers on 10 topics essential for private sector development that correspond to various stages of the life cycle of a firm. The report also offers insights into three cross-cutting themes that are relevant for modern economies: digital adoption, environmental sustainability, and gender. B-READY draws on a robust data collection process that includes specially tailored expert questionnaires and firm-level surveys. The 2024 report, which covers 50 economies, serves as the first in a series that will expand in geographical coverage and refine its methodology over time, supporting reform advocacy, policy guidance, and further analysis and research.Publication Global Economic Prospects, June 2025(Washington, DC: World Bank, 2025-06-10)The global economy is facing another substantial headwind, emanating largely from an increase in trade tensions and heightened global policy uncertainty. For emerging market and developing economies (EMDEs), the ability to boost job creation and reduce extreme poverty has declined. Key downside risks include a further escalation of trade barriers and continued policy uncertainty. These challenges are exacerbated by subdued foreign direct investment into EMDEs. Global cooperation is needed to restore a more stable international trade environment and scale up support for vulnerable countries grappling with conflict, debt burdens, and climate change. Domestic policy action is also critical to contain inflation risks and strengthen fiscal resilience. To accelerate job creation and long-term growth, structural reforms must focus on raising institutional quality, attracting private investment, and strengthening human capital and labor markets. Countries in fragile and conflict situations face daunting development challenges that will require tailored domestic policy reforms and well-coordinated multilateral support.Publication Global Economic Prospects, January 2025(Washington, DC: World Bank, 2025-01-16)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.Publication Digital Progress and Trends Report 2023(Washington, DC: World Bank, 2024-03-05)Digitalization is the transformational opportunity of our time. The digital sector has become a powerhouse of innovation, economic growth, and job creation. Value added in the IT services sector grew at 8 percent annually during 2000–22, nearly twice as fast as the global economy. Employment growth in IT services reached 7 percent annually, six times higher than total employment growth. The diffusion and adoption of digital technologies are just as critical as their invention. Digital uptake has accelerated since the COVID-19 pandemic, with 1.5 billion new internet users added from 2018 to 2022. The share of firms investing in digital solutions around the world has more than doubled from 2020 to 2022. Low-income countries, vulnerable populations, and small firms, however, have been falling behind, while transformative digital innovations such as artificial intelligence (AI) have been accelerating in higher-income countries. Although more than 90 percent of the population in high-income countries was online in 2022, only one in four people in low-income countries used the internet, and the speed of their connection was typically only a small fraction of that in wealthier countries. As businesses in technologically advanced countries integrate generative AI into their products and services, less than half of the businesses in many low- and middle-income countries have an internet connection. The growing digital divide is exacerbating the poverty and productivity gaps between richer and poorer economies. The Digital Progress and Trends Report series will track global digitalization progress and highlight policy trends, debates, and implications for low- and middle-income countries. The series adds to the global efforts to study the progress and trends of digitalization in two main ways: · By compiling, curating, and analyzing data from diverse sources to present a comprehensive picture of digitalization in low- and middle-income countries, including in-depth analyses on understudied topics. · By developing insights on policy opportunities, challenges, and debates and reflecting the perspectives of various stakeholders and the World Bank’s operational experiences. This report, the first in the series, aims to inform evidence-based policy making and motivate action among internal and external audiences and stakeholders. The report will bring global attention to high-performing countries that have valuable experience to share as well as to areas where efforts will need to be redoubled.Publication The Container Port Performance Index 2023(Washington, DC: World Bank, 2024-07-18)The Container Port Performance Index (CPPI) measures the time container ships spend in port, making it an important point of reference for stakeholders in the global economy. These stakeholders include port authorities and operators, national governments, supranational organizations, development agencies, and other public and private players in trade and logistics. The index highlights where vessel time in container ports could be improved. Streamlining these processes would benefit all parties involved, including shipping lines, national governments, and consumers. This fourth edition of the CPPI relies on data from 405 container ports with at least 24 container ship port calls in the calendar year 2023. As in earlier editions of the CPPI, the ranking employs two different methodological approaches: an administrative (technical) approach and a statistical approach (using matrix factorization). Combining these two approaches ensures that the overall ranking of container ports reflects actual port performance as closely as possible while also being statistically robust. The CPPI methodology assesses the sequential steps of a container ship port call. ‘Total port hours’ refers to the total time elapsed from the moment a ship arrives at the port until the vessel leaves the berth after completing its cargo operations. The CPPI uses time as an indicator because time is very important to shipping lines, ports, and the entire logistics chain. However, time, as captured by the CPPI, is not the only way to measure port efficiency, so it does not tell the entire story of a port’s performance. Factors that can influence the time vessels spend in ports can be location-specific and under the port’s control (endogenous) or external and beyond the control of the port (exogenous). The CPPI measures time spent in container ports, strictly based on quantitative data only, which do not reveal the underlying factors or root causes of extended port times. A detailed port-specific diagnostic would be required to assess the contribution of underlying factors to the time a vessel spends in port. A very low ranking or a significant change in ranking may warrant special attention, for which the World Bank generally recommends a detailed diagnostic.
