Abstract
Using a database of 76,046 empirical economics papers published between 1985 and 2005, we report two associations. First, research output on a given country increases with the country's population and wealth, yielding a strong correlation between per-capita research output and per-capita GDP. Regressions controlling for data quality, governance and the use of English give an estimated research–wealth elasticity of 0.32; surprisingly, the U.S. is not an outlier. Second, papers written about the U.S. are 2.5 percentage-points more likely to be published in the top five economics journals after accounting for authors' institutional affiliations and the field of study. This is a large effect because only 1.5% of all papers written about countries other than the U.S. are published in first-tier journals. No similar premium for research on the U.S. is detected in second-tier general interest journals, where papers from the UK and Europe command a substantial premium instead.

Publication U.S. and Them : The Geography of Academic Research(2009-12)Using a database of 76,046 empirical economics papers published between 1985 and 2004 in the top 202 economics journals, the authors report two associations. First, per-capita research output on a given country increases with the country's per capita gross domestic product (GDP). Regressions controlling for data availability and quality in the country, indicators of governance and the use of English yield an estimated research-GDP elasticity of 0.37; surprisingly, the United States (US) is not an outlier in the production of empirical research. Second, papers written about the US are far more likely to be published in the top five economics journals, even after the quality of research has been partially controlled for through fixed-effects for the authors' institutional affiliations; the estimates suggest that papers on the US are 2.6 percentage points more likely to be published in the top-five journals. This is a large effect because only 1.5 percent of all papers written about countries other than the US are published in the top-five journals. The authors speculate about the interpretations of these facts, and invite further analysis and additions to the public release of the database that accompanies this paper.Publication Handwashing Behavior Change at Scale : Evidence from a Randomized Evaluation in Vietnam(World Bank, Washington, DC, 2012-09)Handwashing with soap, which has been shown to reduce diarrhea in young children by as much as 48 percent, is frequently mentioned as one of the most effective and inexpensive ways to save children's lives. Yet rates of handwashing remain very low throughout the world. Handwashing with soap campaigns are de rigueur in developing countries, but little is known about their effectiveness. Few have been rigorously evaluated, and none on a large-scale. This paper evaluates a large-scale handwashing campaign in three provinces of Vietnam in 2010. Exposure to the campaign resulted in a slight increase in the availability of handwashing materials in the household, and caregivers in the treatment group were more likely to report washing hands at some of the times emphasized by the campaign. However, observed handwashing with soap at these times is low, and there isn't any difference between the treatment and control groups. As a result, no impact on health or productivity is found. These results suggest that even under seemingly optimal conditions, where knowledge and access to soap and water are not main constraints, behavior change campaigns that take place on a large scale face tradeoffs in terms of intensity and effectiveness.Publication Reassessing Conditional Cash Transfer Programs(Oxford University Press on behalf of the World Bank, 2005-03-01)During the past decade, the use of conditional cash transfer programs to increase investment in human capital has generated considerable excitement in both research and policy forums. This article surveys the existing literature, which suggests that most conditional cash transfer programs are used for essentially one of two purposes: restoring efficiency when externalities exist or improving equity by targeting resources to poor households. The programs often meet their stated objectives, but in some instances there is tension between the efficiency and equity objectives. The overall impact of a program depends on the gains and losses associated with each objective.Publication Broken Gears : The Value Added of Higher Education on Teachers' Academic Achievement(World Bank Group, Washington, DC, 2015-01)Good teachers are essential for high-quality educational systems. However, little is known about teachers' skills formation during college. By combining two standardized tests for Colombian students, one taken at the end of senior year in high school and the other when students are near graduation from college, this paper documents the extent to which education majors relatively improve or deteriorate their skills in quantitative reasoning, native language, and foreign language, in comparison to students in other programs. Teachers' skills vis-a-vis those in other majors deteriorate in quantitative reasoning and foreign language, although they deteriorate less for those in math-oriented and foreign language-oriented programs. For native language, there is no evidence of robust differences in relative learning mobility.Publication The Economic Consequences of “Brain Drain” of the Best and Brightest : Microeconomic Evidence from Five Countries(2010-08-01)Brain drain has long been a common concern for migrant-sending countries, particularly for small countries where high-skilled emigration rates are highest. However, while economic theory suggests a number of possible benefits, in addition to costs, from skilled emigration, the evidence base on many of these is very limited. Moreover, the lessons from case studies of benefits to China and India from skilled emigration may not be relevant to much smaller countries. This paper presents the results of innovative surveys which tracked academic high-achievers from five countries to wherever they moved in the world in order to directly measure at the micro level the channels through which high-skilled emigration affects the sending country. The results show that there are very high levels of emigration and of return migration among the very highly skilled; the income gains to the best and brightest from migrating are very large, and an order of magnitude or more greater than any other effect; there are large benefits from migration in terms of postgraduate education; most high-skilled migrants from poorer countries send remittances; but that involvement in trade and foreign direct investment is a rare occurrence. There is considerable knowledge flow from both current and return migrants about job and study opportunities abroad, but little net knowledge sharing from current migrants to home country governments or businesses. Finally, the fiscal costs vary considerably across countries, and depend on the extent to which governments rely on progressive income taxation.

Publication Economic Recovery(World Bank, Washington, DC, 2021-04-06)World Bank Group President David Malpass spoke about the world facing major challenges, including COVID, climate change, rising poverty and inequality and growing fragility and violence in many countries. He highlighted vaccines, working closely with Gavi, WHO, and UNICEF, the World Bank has conducted over one hundred capacity assessments, many even more before vaccines were available. The World Bank Group worked to achieve a debt service suspension initiative and increased transparency in debt contracts at developing countries. The World Bank Group is finalizing a new climate change action plan, which includes a big step up in financing, building on their record climate financing over the past two years. He noted big challenges to bring all together to achieve GRID: green, resilient, and inclusive development. Janet Yellen, U.S. Secretary of the Treasury, mentioned focusing on vulnerable people during the pandemic. Kristalina Georgieva, Managing Director of the International Monetary Fund, focused on giving everyone a fair shot during a sustainable recovery. All three commented on the importance of tackling climate change.Publication Sourcebook on the Foundations of Social Protection Delivery Systems(Washington, DC: World Bank, 2020-07-30)The Sourcebook synthesizes real-world experiences and lessons learned of social protection delivery systems from around the world, with a particular focus on social and labor benefits and services. It takes a practical approach, seeking to address concrete “how-to” questions, including: How do countries deliver social protection benefits and services? How do they do so effectively and efficiently? How do they ensure dynamic inclusion, especially for the most vulnerable and needy? How do they promote better coordination and integration—not only among social protection programs but also programs in other parts of government? How can they meet the needs of their intended populations and provide a better client experience? The Sourcebook structures itself around eight key principles that can frame the delivery systems mindset: (1) delivery systems evolve over time, do so in a non-linear fashion, and are affected by the starting point(s); (2) additional efforts should be made to “do simple well”, and to do so from the start rather than trying to remedy by after-the-fact adding-on of features or aspects; (3) quality implementation matters, and weaknesses in the design or structure of any core system element will negatively impact delivery; (4) defining the “first mile” for people interface greatly affects the system and overall delivery, and is most improved when that “first mile” is understood as the weakest link in delivery systems); (5) delivery systems do not operate in a vacuum and thus should not be developed in silos; (6) delivery systems can contribute more broadly to government’s ability to intervene in other sectors, such as health insurance subsidies, scholarships, social energy tariffs, housing benefits, and legal services; (7) there is no single blueprint for delivery systems, but there are commonalities and those common elements constitute the core of the delivery systems framework; (8) inclusion and coordination are pervasive and perennial dual challenges, and they contribute to the objectives of effectiveness and efficiency.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 Rental Housing : Lessons from International Experience and Policies for Emerging Markets(Washington, DC: World Bank, 2013-03-22)This book rental housing lessons from international experience and policies for emerging market is an effort to bring rental housing to the forefront of the housing agenda of countries around the world and to provide general guidance for policy makers whose actions can have an effect on where and how people live. It warns of the challenges they face and provides guidelines on how to develop or redevelop a sound rental sector. it can enable key players in housing markets be they government officials, private rental property owners, financiers, or nongovernmental organizations to add rental housing as a critical housing option and to have an informed discussion on how best to stimulate this sector. The housing policy of most nations focused on increasing home ownership. There had been very little discussion about rental housing, less about social housing, and virtually none about public housing. This book includes totally five chapters: chapter one is introduction; chapter two is the rental market and its players; chapter three is legal, tax, and financial issues; chapter four is recommendations and conclusion; chapter five is country experiences.Publication Media and Messages for Nutrition and Health(World Bank, Washington, DC, 2020-06)The Lao People’s Democratic Republic (Lao PDR) has experienced rapid and significant economic growth over the past decade. However, poor nutritional outcomes remain a concern. Rates of childhood undernutrition are particularly high in remote, rural, and upland areas. Media have the potential to play an important role in shaping health and nutrition–related behaviors and practices as well as in promoting sociocultural and economic development that might contribute to improved nutritional outcomes. This report presents the results of a media audit (MA) that was conducted to inform the development and production of mass media advocacy and communication strategies and materials with a focus on maternal and child health and nutrition that would reach the most people from the poorest communities in northern Lao PDR. Making more people aware of useful information, essential services and products and influencing them to use these effectively is the ultimate goal of mass media campaigns, and the MA measures the potential effectiveness of media efforts to reach this goal. The effectiveness of communication channels to deliver health and nutrition messages to target beneficiaries to ensure maximum reach and uptake can be viewed in terms of preferences, satisfaction, and trust. Overall, the four most accessed media channels for receiving information among communities in the study areas were village announcements, mobile phones, television, and out-of-home (OOH) media. Of the accessed media channels, the top three most preferred channels were village announcements (40 percent), television (26 percent), and mobile phones (19 percent). In terms of trust, village announcements were the most trusted source of information (64 percent), followed by mobile phones (14 percent) and television (11 percent). Hence of all the media channels, village announcements are the most preferred, have the most satisfied users, and are the most trusted source of information in study communities from four provinces in Lao PDR with some of the highest burden of childhood undernutrition.
