Abstract
This Brief introduces the Justice Pillars Towards Evidence-Based Reform (JUPITER) initiative, a standardized yet flexible, country-based assessment tool that evaluates the effectiveness of justice systems across countries. Developed by the World Bank’s Global Program on Justice and the Rule of Law, JUPITER aims at identifying strengths and weaknesses in key pillars of judicial performance—access, efficiency, and quality. The Brief lays out key advantages of JUPITER’s comprehensive approach: its focus on areas with an empirical link to outcomes as investigated in rigorous academic research; its emphasis on the law as well as its application, which enables the identification of potential implementation gaps; its assessment of both the formal and customary justice institutions; and its coverage of the entire country. In so doing, we bring examples from its application in some of the poorest and most fragile countries in the world such as Liberia and South Sudan. This Brief explains the significance of access, efficiency, and quality for the effectiveness of justice delivery and how JUPITER measures performance in each of those areas. It concludes by discussing how the methodology could enable cross-country comparisons as more data is gathered through the JUPITER assessment

Publication The Juicio Ejecutivo Mercantil in the Federal District Courts of Mexico : A Study of the Uses and Users of Justice and Their Implications for Judicial Reform(Washington, DC, 2002-06-22)The report reviews the research conducted in Mexico's Federal District courts on the summary debt collection proceedings - Juicio Ejecutivo Mercantil (JEM) - as a result of a specific request from the Government, to study the judiciary's impact on contract enforcement, as well as because of the Bank's assistance strategy, which emphasizes on supporting improved governance, and an enabling environment for private sector development. Following an introductory chapter, the second chapter briefly summarizes debates about judicial reform, and their political, theoretical, and empirical foundations, while chapter 3 discusses the objectives, and methodology of the study. Chapter 4 provides an overview of the Mexican judicial system, and Federal District courts. Starting with Chapter 5, the most important research findings are reported: it analyzes the users of the commercial justice. Interestingly, the principal parties to the proceedings are individuals, claims are relatively small, and, a 90 percent of those cases where a judgment is delivered, favors the plaintiff. Chapters 6, 7, and 8 report findings on the trajectory of JEM cases, and its dynamic perspective, that assumes different paths, and reaches diverse outcomes. Some of the recommendations include improved supervision regarding bailiffs resolution; formalization of execution proceedings, and, reconsideration of the nature of due process guarantees in commercial proceedings.Publication Institutional Reform and the Judiciary : Which Way Forward?(World Bank, Washington, DC, 2003-09)The author presents some general lessons in institution-building that has relevance for judiciary reform. She emphasizes the value of simplicity in design commensurate with country capacity, the importance of innovation and experimentation, and of economic openness in effective institution-building. The author underscores how the incentives of individuals depend on both the details of institutional design within the judiciary and also some critical institutions external to the judiciary. Finally she argues for the need to ground reform initiatives on a solid empirical and comparative approach. The author illustrates some of these issues by drawing on a recent project conducted by the World Bank and other institutions.Publication Vested Interests in Legal and Judicial Reform(Washington, DC, 2008-05)This report analyzes the main reasons or interests that have prevented some recent judicial and legal reforms in Honduras and Bolivia from becoming effective. It focuses on the reasons why criminal justice reforms were unable to put an end to the misuse of pre-trial detention. The report also includes a study of some of the reasons that have prevented criminal procedure code reforms from reducing the perception of impunity prevailing in both countries. With respect to the reforms of judicial selection mechanisms, it focuses on the interests that have prevented the public perception of judicial independence from improving in spite of the implementation of those reforms. The report includes an annex to Section 1, consultations with civil society in Honduras. Section 2 discusses civil and commercial justice in Paraguay. Section 3 discusses vested interests in legal and judicial reform projects in Guyana.Publication Justice Sector Reform in Mongolia : Looking Back, Looking Forward(World Bank, Washington, DC, 2011-01)The justice sector in Mongolia has changed significantly in the 20 years since the country became a democracy. From the very beginning, the World Bank and other international partners have provided significant assistance to reform processes, particularly in areas concerned with the development of an independent judiciary. Especially in comparison to other countries in the region, Mongolia's reform efforts have been generally successful. During the early and economically difficult times since democracy was established, reform activities naturally focused on legal reforms, including the creation of a legislative framework for democratic institutions, the transition to a market economy, and for needed changes in the relationship between the state and the people. This was followed at the end of the millennium by concerted efforts to reform justice institutions and to improve human capacities for supporting, implementing and sustaining reforms. Mongolia was the first developing nation to pursue comprehensive and inclusive strategic planning for its justice sector. Its strategic plan has provided a roadmap for reforms over many years and withstood leadership changes in both the government and in the key justice agencies. Much has been achieved, considering the challenges that have been overcome in terms of justice system infrastructure, human capacities and changes in attitudes, all with only very limited budget resources. At the same time, reform gaps exist and public trust in the justice sector is lacking. Critics continue to point to weak and uneven decision making capacities of prosecutors and judges, despite more than a decade of intensive donor support for their training. This paper reviews some of the underlying issues affecting justice reforms in Mongolia; and points to areas that require attention to overcome the current shortcomings and challenges.Publication The Role of Justice in Development(World Bank, Washington, DC, 2021-06)This paper summarizes the empirical evidence on the role of justice in economic development, conflict, and trust in institutions. It finds that justice institutions play a significant role in economic development, particularly through their impact on credit markets and firm growth, the protection of vulnerable populations, their capacity to deter violence, and their influence over people’s trust in formal institutions. The paper then considers the promise of administrative data, machine learning, and randomized controlled trials to enhance the efficiency, access, and quality of justice. The paper concludes by discussing new avenues for research and the potential for data to improve the functioning of justice systems in the age of COVID-19.

Publication Europe and Central Asia Economic Update, Spring 2025: Accelerating Growth through Entrepreneurship, Technology Adoption, and Innovation(Washington, DC: World Bank, 2025-04-23)Business dynamism and economic growth in Europe and Central Asia have weakened since the late 2000s, with productivity growth driven largely by resource reallocation between firms and sectors rather than innovation. To move up the value chain, countries need to facilitate technology adoption, stronger domestic competition, and firm-level innovation to build a more dynamic private sector. Governments should move beyond broad support for small- and medium-sized enterprises and focus on enabling the most productive firms to expand and compete globally. Strengthening competition policies, reducing the presence of state-owned enterprises, and ensuring fair market access are crucial. Limited availability of long-term financing and risk capital hinders firm growth and innovation. Economic disruptions are a shock in the short term, but they provide an opportunity for implementing enterprise and structural reforms, all of which are essential for creating better-paying jobs and helping countries in the region to achieve high-income status.Publication Cities’ Partnership Initiative(Washington, DC: World Bank, 2025-04-24)Sustainable urban development is one of the key areas of development policy in Poland, which is in line with global trends. Sustainable urban development requires an integrated approach that takes into account the complexity and dynamics of phenomena and processes taking place in the urban environment. Meeting the challenges of urban development requires, on the one hand, a steady increase in the capacity of cities to plan and implement development projects, and on the other hand, a favorable regulatory and financial framework and support instruments that are an adequate response to the needs of urban centers. The Cities’ Partnership Initiative (CPI) is a flagship project of the Ministry of Development Funds and Regional Policy of Poland (MDFRP) aimed at supporting sustainable urban development. This final report is the third product of the Reimbursable Advisory Service Agreement on Sustainable Urban Development - Cities’ Partnership Initiative concluded between the MDFRP and the World Bank on January 28, 2022. The report summarizes the project work, including the results of the work of 30 CPI-participating cities, and presents conclusions and recommendations on the three thematic networks and the CPI formula itself.Publication State of Social Protection Report 2025(Washington, DC: World Bank, 2025-04-07)Social protection goes well beyond cash transfers; it includes policies and programs that bridge skill, financial, and information gaps, aiding people in securing better jobs. The three pillars of social protection—social assistance, social insurance, and labor market programs—support households and workers in handling crises, escaping poverty, facing transitions, and seizing employment opportunities. But despite a substantial expansion over the past decade, 2 billion people remain uncovered or inadequately covered across low- and middle-income countries. Drawing from administrative and household survey data from the World Bank’s Atlas of Social Protection Indicators of Resilience and Equity (ASPIRE), the "State of Social Protection Report 2025: The 2-Billion-Person Challenge" documents advances and challenges to strengthening social protection and labor systems across low- and middle-income countries, analyzing the evolution of expenditure, coverage, and adequacy of support. This report details four policy action areas governments can embrace to maximize the benefits of adequate social protection for all: extending social protection to those in need; strengthening the adequacy of social protection support; building shock-proof social protection systems; and optimizing social protection financing. The report discusses how the path of reforms will depend on country context, capacity, and fiscal space. The rising frequency of shocks and crises calls for major investments in the adaptability and preparedness of social protection and labor systems. Amid a world in transition, social protection is more important and necessary than ever.Publication South Asia Development Update, April 2025: Taxing Times(Washington, DC: World Bank, 2025-04-23)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.Publication Infrastructure Monitor 2024(Washington, DC: World Bank, 2025-04-28)The Infrastructure Monitor report covers global trends in private investment in infrastructure to inform investors, policy-makers and other practitioners. The objective is to deliver global insights on global infrastructure trends across key topics such as investment volumes, performance, blended finance, and ESG drivers, facilitating the monitoring of private infrastructure investment and its performance. These insights aim to support policymakers, investors, and other stakeholders in developing sustainable, resilient, and inclusive infrastructure while fostering effective partnerships with the private sector. Acknowledging the significant infrastructure data gap — with notable variations in coverage, quality across countries and income groups, and differences in the availability of regional breakdowns — our approach leverages the best available aggregated data from leading infrastructure databases to generate market insights while also providing context on its limitations. 2025 will be the fifth version of the report, the first under the World Bank.
