Abstract
Can the impact of justice processes be enhanced with the inclusion of a heterogeneous component into an existing cost-benefit analysis app that demonstrates how benefactors and beneficiaries are affected Such a component requires (i) moving beyond the traditional cost-benefit conceptual framework of utilizing averages, (ii) identification of social group or population-specific variation, (iii) identification of how justice processes differ across groups/populations, (iv) distribution of costs and benefits according to the identified variations, and (v) utilization of empirically informed statistical techniques to gain new insights from data and maximize the impact for beneficiaries. This paper outlines a method for capturing heterogeneity. The paper tests the method and the cost-benefit analysis online app that was developed using primary data collected from a developmental crime prevention intervention in Australia. The paper identifies how subgroups in the intervention display different behavioral adjustments across the reference period, revealing the heterogeneous distribution of costs and benefits. Finally, the paper discusses the next version of the cost-benefit analysis app, which incorporates an artificial intelligence-driven component that reintegrates individual cost-benefit analysis projects using machine learning and other modern data science techniques. The paper argues that the app enhances cost-benefit analysis, development outcomes, and policy making efficiency for optimal prioritization of criminal justice resources. Further, the app advances the policy accessibility of enhanced, social group-specific data, illuminating optimal policy orientation for more inclusive, just, and resilient societal outcomes—an approach with potential across broader public policy.

Publication Tools for Assessing the Costs and Benefits of Green Growth : The U.S. and Mexico(World Bank, Washington, DC, 2012-10)This paper examines the processes used in the United States and Mexico to assess the economic costs and benefits of environmental improvement, the kinds of information obtained from these procedures, and the additional knowledge that is needed about both elements to improve understanding of the problems and prospects of advancing a green growth agenda. Because environmental and other development needs are large and resources are limited, it is important to choose the best projects, those with the highest returns on both public investments and private resources harnessed by regulation. The United States is well-established as a world leader in the use of quantitative methods to evaluate options for environmental regulation and policy. Mexico represents a case where a developing country has made clear advances in reforming its economy and in introducing transparency in its regulatory processes for environmental and other policy areas.Publication Applying Machine Learning and Geolocation Techniques to Social Media Data (Twitter) to Develop a Resource for Urban Planning(World Bank, Washington, DC, 2020-12)With all the recent attention focused on big data, it is easy to overlook that basic vital statistics remain difficult to obtain in most of the world. This project set out to test whether an openly available dataset (Twitter) could be transformed into a resource for urban planning and development. The hypothesis is tested by creating road traffic crash location data, which are scarce in most resource-poor environments but essential for addressing the number one cause of mortality for children over age five and young adults. The research project scraped 874,588 traffic-related tweets in Nairobi, Kenya, applied a machine learning model to capture the occurrence of a crash, and developed an improved geoparsing algorithm to identify its location. The project geolocated 32,991 crash reports in Twitter for 2012-20 and clustered them into 22,872 unique crashes to produce one of the first crash maps for Nairobi. A motorcycle delivery service was dispatched in real-time to verify a subset of crashes, showing 92 percent accuracy. Using a spatial clustering algorithm, portions of the road network (less than 1 percent) were identified where 50 percent of the geolocated crashes occurred. Even with limitations in the representativeness of the data, the results can provide urban planners useful information to target road safety improvements where resources are limited.Publication Program Targeting with Machine Learning and Mobile Phone Data(World Bank, Washington, DC, 2022-12)Can mobile phone data improve program targeting By combining rich survey data from the baseline of a “big push” anti-poverty program in Afghanistan implemented in 2016 with detailed mobile phone logs from program beneficiaries, this paper studies the extent to which machine learning methods can accurately differentiate ultra-poor households eligible for program benefits from ineligible households. The paper shows that machine learning methods leveraging mobile phone data can identify ultra-poor households nearly as accurately as survey-based measures of consumption and wealth; and that combining survey-based measures with mobile phone data produces classifications more accurate than those based on a single data source.Publication Strategic Environmental Assessment in Policy and Sector Reform : Conceptual Model and Operational Guidance(World Bank, 2011)Around the world, it is increasingly being recognized that for sustainability goals to be reached, efforts need to go beyond complying with standards and mitigating adverse impacts, to identifying environmental sustainability as an objective of the development process. This approach requires the integration of environmental, sustainability, and climate change considerations into policy and sector reform. Because sector reform brings about significant policy change involving adjustments in laws, policies, regulations, and institutions, it is a sensitive political process often driven by strong economic interests. Policy makers are subject to a number of political pressures that originate in vested interests. The recommendations of environmental assessment are often of little relevance unless there are constituencies that support them and have sufficient political power to make their voices heard in the policy process. While strong constituencies are important during the design of sector reform, they are even more important during implementation. It follows that effective environmental assessment in policy and sector reform requires strong constituencies backing up recommendations, a system to hold policy makers accountable for their decisions, and institutions that can balance competing and, sometimes, conflicting interests.Publication Cost-Benefit Analysis in World Bank Projects(Washington, DC: World Bank, 2010)This report has been prepared in the context of a major global effort in the past eight years to better measure results in development assistance. The agenda for this effort was articulated and refined in a series of international conferences, beginning with the international conference on financing for development in Monterrey in 2002 and continuing through the Accra agenda for action in 2008. Cost-benefit analysis entails measuring results, valuing results, and comparing results with costs, and hence is highly relevant to the results agenda. Cost-benefit analysis can provide a comprehensive picture of the net impact of projects and help direct funds to where their development effectiveness is highest. This study draws two broad conclusions. First, the bank needs to revisit its policy for cost-benefit analysis in a way that recognizes the legitimate difficulties in quantifying benefits while preserving a high degree of rigor in justifying projects. Second, the bank needs to ensure that cost-benefit analysis is done with quality, rigor, and objectivity: poor data and analysis misinform, and do not improve, results. Reforms are required to project-appraisal procedures to ensure objectivity, improve both the analysis and the use of evidence at appraisal, and ensure effective use of cost benefit analysis in decision making.

Publication World Development Report 2011(World Bank, 2011)The 2011 World development report looks across disciplines and experiences drawn from around the world to offer some ideas and practical recommendations on how to move beyond conflict and fragility and secure development. The key messages are important for all countries-low, middle, and high income-as well as for regional and global institutions: first, institutional legitimacy is the key to stability. When state institutions do not adequately protect citizens, guard against corruption, or provide access to justice; when markets do not provide job opportunities; or when communities have lost social cohesion-the likelihood of violent conflict increases. Second, investing in citizen security, justice, and jobs is essential to reducing violence. But there are major structural gaps in our collective capabilities to support these areas. Third, confronting this challenge effectively means that institutions need to change. International agencies and partners from other countries must adapt procedures so they can respond with agility and speed, a longer-term perspective, and greater staying power. Fourth, need to adopt a layered approach. Some problems can be addressed at the country level, but others need to be addressed at a regional level, such as developing markets that integrate insecure areas and pooling resources for building capacity Fifth, in adopting these approaches, need to be aware that the global landscape is changing. Regional institutions and middle income countries are playing a larger role. This means should pay more attention to south-south and south-north exchanges, and to the recent transition experiences of middle income countries.Publication Remarks to the Annual Meetings 2020 Development Committee(World Bank, Washington, DC, 2020-10-16)David Malpass, President of the World Bank Group, announced that the Board approved a fast track approach to emergency health support programs that now covers 111 countries. Most projects are well advanced, with average disbursement upward of 40 percent. The goal is to take broad, fast action early. The operational framework presented back in June has positioned the Bank to help countries address immediate health threats and social and economic impacts and maintain our focus on long-term development. The Bank is making good progress toward the 15-month target of 160 billion dollars in surge financing. Much of it is for the poorest countries and will take the form of grants or low-rate, long-maturity loans. IFC, through the Global Health Platform, will be providing financing to vaccine manufacturers to foster expanded production of COVID-19 vaccines in both part 1 and 2 countries, providing production is reserved for emerging markets. The Development Committee holds a unique place in the international architecture. It is the only global forum in which the Governments of developed countries and the Governments of developing countries, creditor countries and borrower countries, come together to discuss development and the ‘net transfer of resources to developing countries.’ The current International Financial Architecture system is skewed in favor of the rich and creditor countries. It is important that all voices are heard, so Malpass urged the Ministers of developing countries to use their voice and speak their minds today. Malpass urged consideration of how we can build a new approach to debt restructuring that allows for a fair relationship and balance between creditors and debtors. This will be critical in restoring growth in developing countries; and helping reverse the inequality.Publication World Development Report 2006(Washington, DC, 2005)This year’s Word Development Report (WDR), the twenty-eighth, looks at the role of equity in the development process. It defines equity in terms of two basic principles. The first is equal opportunities: that a person’s chances in life should be determined by his or her talents and efforts, rather than by pre-determined circumstances such as race, gender, social or family background. The second principle is the avoidance of extreme deprivation in outcomes, particularly in health, education and consumption levels. This principle thus includes the objective of poverty reduction. The report’s main message is that, in the long run, the pursuit of equity and the pursuit of economic prosperity are complementary. In addition to detailed chapters exploring these and related issues, the Report contains selected data from the World Development Indicators 2005‹an appendix of economic and social data for over 200 countries. This Report offers practical insights for policymakers, executives, scholars, and all those with an interest in economic development.Publication Classroom Assessment to Support Foundational Literacy(Washington, DC: World Bank, 2025-03-21)This document focuses primarily on how classroom assessment activities can measure students’ literacy skills as they progress along a learning trajectory towards reading fluently and with comprehension by the end of primary school grades. The document addresses considerations regarding the design and implementation of early grade reading classroom assessment, provides examples of assessment activities from a variety of countries and contexts, and discusses the importance of incorporating classroom assessment practices into teacher training and professional development opportunities for teachers. The structure of the document is as follows. The first section presents definitions and addresses basic questions on classroom assessment. Section 2 covers the intersection between assessment and early grade reading by discussing how learning assessment can measure early grade reading skills following the reading learning trajectory. Section 3 compares some of the most common early grade literacy assessment tools with respect to the early grade reading skills and developmental phases. Section 4 of the document addresses teacher training considerations in developing, scoring, and using early grade reading assessment. Additional issues in assessing reading skills in the classroom and using assessment results to improve teaching and learning are reviewed in section 5. Throughout the document, country cases are presented to demonstrate how assessment activities can be implemented in the classroom in different contexts.Publication Doing Business 2014 : Understanding Regulations for Small and Medium-Size Enterprises(Washington, DC: World Bank Group, 2013-10-28)Eleventh in a series of annual reports comparing business regulation in 185 economies, Doing Business 2014 measures regulations affecting 11 areas of everyday business activity: Starting a business, Dealing with construction permits, Getting electricity, Registering property, Getting credit, Protecting investors, Paying taxes, Trading across borders, Enforcing contracts, Closing a business, Employing workers. The report updates all indicators as of June 1, 2013, ranks economies on their overall “ease of doing business”, and analyzes reforms to business regulation – identifying which economies are strengthening their business environment the most. The Doing Business reports illustrate how reforms in business regulations are being used to analyze economic outcomes for domestic entrepreneurs and for the wider economy. Doing Business is a flagship product by the World Bank and IFC that garners worldwide attention on regulatory barriers to entrepreneurship. More than 60 economies use the Doing Business indicators to shape reform agendas and monitor improvements on the ground. In addition, the Doing Business data has generated over 870 articles in peer-reviewed academic journals since its inception.
