Abstract
The Coronavirus disease 2019 (COVID-19) high-frequency phone survey (HFPS) 2020 was conducted in 13 Latin American countries: Argentina, Bolivia, Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Paraguay, and Peru. It followed a panel sample over three waves of data collection in 12 countries and over four waves in Ecuador. All waves spanned from May to August 2020 and each wave’s collection period lasted about ten days on average. The survey was administered to one adult per household. Each respondent was presented with both individual and household-level questions. All national samples were based on a dual frame of cell and landline phones, and selected as a one-stage probability sample, with geographic stratification of landline numbers. The samples were generated through a random digit dialing (RDD) process covering all cell and landline telephone numbers active at the time of the sample selection. Survey estimates represent households with a landline or at least one cell phone and individuals of 18 years of age or above who have an active cell phone number or a landline at home.

Publication Papua New Guinea High Frequency Phone Survey on COVID-19, December 2020 to January 2021(World Bank, Washington, DC, 2021)This joint report by the World Bank and United Nations International Children’s Emergency Fund (UNICEF) Papua New Guinea (PNG) presents the findings from two mobile phone surveys conducted in December 2020 and January 2021 in PNG. The World Bank survey, conducted in December 2020, was the second in a series. The UNICEF survey, conducted in January 2021, targeted re-contacting all 2,534 households from the World Bank round 2 survey with children under the age of 15, and achieved a final sample of 2,449. These results were also weighted using information from the demographic and health survey (DHS) to develop representative estimates for households with children under 15, 79.8 percent according to the DHS. The UNICEF survey included sections on household impacts as well as on the children living within the household. Compared to the rest of the country, markedly higher shares of respondents in the NCD noted deteriorations since June in situations related to theft, alcohol, and drug abuse, intimidation by police, violence by police, and domestic abuse, as well as higher declines in overall community trust, which can be an indicator of rising tensions. In addition, there were potential warning signs of the impacts of the prolonged crisis on children, with more than one-third of children exhibiting negative behavioral changes in the previous 15 days - though again a lack of baseline data limits the ability to establish a causal link specifically with Coronavirus disease 2019 (COVID-19).Publication Solomon Islands High Frequency Phone Survey on COVID-19(World Bank, Washington, DC, 2020-10-30)The Solomon Islands is a lower middle income small island state in the Melanesian region of the Southwest Pacific. Agriculture, including logging, is central to the economy of the Solomon Islands. To protect the country from importation of Coronavirus (COVID-19) and to limit the possible spread of undiagnosed cases, beginning March 27, the government enacted a series of emergency measures under the State of Public Emergency (SoPE). Coronavirus (COVID-19) response measures, both domestically and abroad, are expected to have negative impacts on the economy and on livelihoods. A strong evidence base is needed to understand the socioeconomic implications of the coronavirus pandemic for the Solomon Islands. The objective of this survey was to measure the socioeconomic impacts of the Coronavirus (COVID-19) global pandemic in the Solomon Islands, including livelihoods, food security, and public safety and security, through a high frequency mobile phone survey.Publication Papua New Guinea High Frequency Phone Survey on COVID-19(World Bank, Washington, DC, 2020-08-06)Papua New Guinea (PNG) is the largest country in the Pacific region, and one of the most diverse countries in the world. The key development challenge in this lower-middle income country is how to translate macroeconomic gains from the resource sector into better opportunities and services for PNG’s largely poor and rural populations. The Coronavirus (COVID-19) pandemic has compounded issues for an already weakening economic situation. A strong evidence base is needed to understand the socioeconomic implications of the coronavirus pandemic for Papua New Guinea. Data is needed to inform the policy response to the coronavirus crisis. To monitor and assess the socio-economic impacts of Coronavirus (COVID-19) in Papua New Guinea, five rounds of High Frequency Phone Surveys (HFPS) have been planned and will be conducted quarterly. Data collection began in late June 2020. This report presents the findings from round one and concludes with a policy section to help inform an evidence-based response to Coronavirus (COVID-19) in Papua New Guinea.Publication High-Frequency Phone Survey (HFPS) - Phase 2(World Bank, Washington, DC, 2022-12)After implementing Phase 1 of the High-Frequency Phone Survey (HFPS) project in Latin America and The Caribbean (LAC) in 2020, the World Bank conducted Phase 2 in 2021 to continue to assess the socio-economic impacts of the COVID-19 pandemic on households. This new phase, conducted in partnership with the UNDP LAC Chief Economist office, included two waves. Wave 1 covered 24 countries and Wave 2 covered 22 countries. Of these countries, 13 participated in Phase 1 and the rest joined in Phase 2. This document describes the sampling design, weighting and the right procedure to estimate indicators for the LAC HFPS Phase 2 surveys.Publication 2021 LAC High Frequency Phone Surveys(World Bank, Washington, DC, 2022-04)The World Bank and UNDP conducted a multi-wave High-Frequency Phone Survey (HFPS) in 2021 to assess the impact of the coronavirus pandemic on the welfare of Latin American and Caribbean households. The first wave was collected between May and July 2021, and the data is nationally representative for 24 countries: Antigua & Barbuda, Argentina, Belize, Bolivia, Brazil, Chile, Colombia, Costa Rica, Dominica, Dominican Republic, Ecuador, El Salvador, Guatemala, Guyana, Haiti, Honduras, Jamaica, Mexico, Nicaragua, Panama, Paraguay, Peru, Saint Lucia and Uruguay. he HFPS provides information on the welfare impacts that households experienced with respect to food insecurity, changes in employment, income changes, access to health and education services, and coping mechanisms.

Publication World Development Report 2020(Washington, DC: World Bank, 2020)Global value chains (GVCs) powered the surge of international trade after 1990 and now account for almost half of all trade. This shift enabled an unprecedented economic convergence: poor countries grew rapidly and began to catch up with richer countries. Since the 2008 global financial crisis, however, the growth of trade has been sluggish and the expansion of GVCs has stalled. Meanwhile, serious threats have emerged to the model of trade-led growth. New technologies could draw production closer to the consumer and reduce the demand for labor. And conflicts among large countries could lead to a retrenchment or a segmentation of GVCs. This book examines whether there is still a path to development through GVCs and trade. It concludes that technological change is, at this stage, more a boon than a curse. GVCs can continue to boost growth, create better jobs, and reduce poverty provided that developing countries implement deeper reforms to promote GVC participation; industrial countries pursue open, predictable policies; and all countries revive multilateral cooperation.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 Unlocking the Power of Healthy Longevity(Washington, DC: World Bank, 2024-09-12)Noncommunicable diseases (NCDs) are among the major health and development challenges of our time. Every year, about 41 million people die due to NCDs. This makes up about 74 percent of all deaths globally, the majority of which are in low- and middle-income countries (LMICs). Countless more people live with NCDs every day. Yet, NCDs are largely treatable and preventable. The risk of developing NCDs and deaths from them can both be lowered with appropriate attention to prevention and treatment. However, weak health systems and limited access to affordable care and information, especially in LMICs, contribute to lapses in seeking and receiving appropriate and timely care. This compendium is a compilation of 18 chapters, each exploring a different but related topic in the nexus of NCDs, human capital, and productivity. It is based on a series of analytical work taken up by the World Bank to support the Healthy Longevity Initiative (HLI) - a collaborative effort between the World Bank, the University of Toronto, and key academic and development partners including the Harvard University and the University of Washington. The HLI presents one of a growing set of efforts to increase the urgency of policy response to NCDs across the world.Publication World Development Report 2018(Washington, DC: World Bank, 2018)Every year, the World Bank's World Development Report takes on a topic of central importance to global development. The 2018 Report, Learning to Realize Education's Promise, is the first ever devoted entirely to education. Now is an excellent time for it: education has long been critical for human welfare, but is even more so in a time of rapid economic change. The Report explores four main themes. First, education's promise: Education is a powerful instrument for eradicating poverty and promoting shared prosperity, but fulfilling its potential requires better policies - both within and outside the education system. Second, the learning crisis: Despite gains in education access, recent learning assessments show that many young people around the world, especially from poor families, are leaving school unequipped with even the most foundational skills they need for life. At the same time, internationally comparable learning assessments show that skills in many middle-income countries lag far behind what those countries aspire to. Third, promising interventions to improve learning: Research from areas such as brain science, pedagogical innovations, or school management have identified interventions that promote learning by ensuring that learners are prepared, that teachers are skilled as well as motivated, and that other inputs support the teacher-learner relationship. Fourth, learning at scale: Achieving learning throughout an education system will require more than just scaling up effective interventions. Change requires overcoming technical and political barriers by deploying salient metrics for mobilizing actors and tracking progress, building coalitions for learning, and being adaptive when implementing programs.Publication World Development Report 2021(Washington, DC: World Bank, 2021-03-24)Today’s unprecedented growth of data and their ubiquity in our lives are signs that the data revolution is transforming the world. And yet much of the value of data remains untapped. Data collected for one purpose have the potential to generate economic and social value in applications far beyond those originally anticipated. But many barriers stand in the way, ranging from misaligned incentives and incompatible data systems to a fundamental lack of trust. World Development Report 2021: Data for Better Lives explores the tremendous potential of the changing data landscape to improve the lives of poor people, while also acknowledging its potential to open back doors that can harm individuals, businesses, and societies. To address this tension between the helpful and harmful potential of data, this Report calls for a new social contract that enables the use and reuse of data to create economic and social value, ensures equitable access to that value, and fosters trust that data will not be misused in harmful ways. This Report begins by assessing how better use and reuse of data can enhance the design of public policies, programs, and service delivery, as well as improve market efficiency and job creation through private sector growth. Because better data governance is key to realizing this value, the Report then looks at how infrastructure policy, data regulation, economic policies, and institutional capabilities enable the sharing of data for their economic and social benefits, while safeguarding against harmful outcomes. The Report concludes by pulling together the pieces and offering an aspirational vision of an integrated national data system that would deliver on the promise of producing high-quality data and making them accessible in a way that promotes their safe use and reuse. By examining these opportunities and challenges, the Report shows how data can benefit the lives of all people, but particularly poor people in low- and middle-income countries.
