Abstract
The main purpose of this paper is to summarize the information currently available on cocaine production and trafficking. The paper starts by describing the available data on cocaine production and trade, the collection methodologies (if available) used by different sources, the main biases in the data, and the accuracy of different data sources. Next, it states some of the key empirical questions and hypotheses regarding cocaine production and trade and takes a first look at how well the data match these hypotheses. The paper states some of the main puzzles in the cocaine market and studies some of the possible explanations. These puzzles and empirical questions should guide future research on the key determinants of illicit drug production and trafficking. Finally, the paper studies the different policies that producer countries have adopted to fight against cocaine production and the role consumer countries play in the implementation of anti-drug policies.

    The Economic Value of Weather Forecasts: A Quantitative Systematic Literature Review
    (Washington, DC: World Bank, 2025-09-10) Farkas, Hannah; Linsenmeier, Manuel; Talevi, Marta; Avner, Paolo; Jafino, Bramka Arga; Sidibe, Moussa
    This study systematically reviews the literature that quantifies the economic benefits of weather observations and forecasts in four weather-dependent economic sectors: agriculture, energy, transport, and disaster-risk management. The review covers 175 peer-reviewed journal articles and 15 policy reports. Findings show that the literature is concentrated in high-income countries and most studies use theoretical models, followed by observational and then experimental research designs. Forecast horizons studied, meteorological variables and services, and monetization techniques vary markedly by sector. Estimated benefits even within specific subsectors span several orders of magnitude and broad uncertainty ranges. An econometric meta-analysis suggests that theoretical studies and studies in richer countries tend to report significantly larger values. Barriers that hinder value realization are identified on both the provider and user sides, with inadequate relevance, weak dissemination, and limited ability to act recurring across sectors. Policy reports rely heavily on back-of-the-envelope or recursive benefit-transfer estimates, rather than on the methods and results of the peer-reviewed literature, revealing a science-to-policy gap. These findings suggest substantial socioeconomic potential of hydrometeorological services around the world, but also knowledge gaps that require more valuation studies focusing on low- and middle-income countries, addressing provider- and user-side barriers and employing rigorous empirical valuation methods to complement and validate theoretical models.

    The Macroeconomic Implications of Climate Change Impacts and Adaptation Options
    (Washington, DC: World Bank, 2025-05-29) Abalo, Kodzovi; Boehlert, Brent; Bui, Thanh; Burns, Andrew; Castillo, Diego; Chewpreecha, Unnada; Haider, Alexander; Hallegatte, Stephane; Jooste, Charl; McIsaac, Florent; Ruberl, Heather; Smet, Kim; Strzepek, Ken
    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.

    Labor Demand in the Age of Generative AI: Early Evidence from the U.S. Job Posting Data
    (Washington, DC: World Bank, 2025-11-18) Liu, Yan; Wang, He; Yu, Shu
    This paper examines the causal impact of generative artificial intelligence on U.S. labor demand using online job posting data. Exploiting ChatGPT’s release in November 2022 as an exogenous shock, the paper applies difference-in-differences and event study designs to estimate the job displacement effects of generative artificial intelligence. The identification strategy compares labor demand for occupations with high versus low artificial intelligence substitution vulnerability following ChatGPT’s launch, conditioning on similar generative artificial intelligence exposure levels to isolate substitution effects from complementary uses. The analysis uses 285 million job postings collected by Lightcast from the first quarter of 2018 to the second quarter of 2025Q2. The findings show that the number of postings for occupations with above-median artificial intelligence substitution scores fell by an average of 12 percent relative to those with below-median scores. The effect increased from 6 percent in the first year after the launch to 18 percent by the third year. Losses were particularly acute for entry-level positions that require neither advanced degrees (18 percent) nor extensive experience (20 percent), as well as those in administrative support (40 percent) and professional services (30 percent). Although generative artificial intelligence generates new occupations and enhances productivity, which may increase labor demand, early evidence suggests that some occupations may be less likely to be complemented by generative artificial intelligence than others.

    The Lasting Effects of Working while in School
    (Washington, DC: World Bank, 2025-08-18) Ferrando, Mery; Katzkowicz, Noemi; Le Barbanchon, Thomas; Ubfal, Diego
    This paper provides the first experimental evidence on the long-term effects of work-study programs, leveraging a randomized lottery design from a national program in Uruguay. Participation leads to a persistent 11 percent increase in formal labor earnings, observable seven years after the program. Effects are stronger for youth who participate during pivotal educational transitions and are larger for vulnerable youth and men, while remaining positive for women and non-vulnerable youth. The program is highly cost-effective, with average impacts exceeding those of job training programs and comparable to early childhood investments.

    It’s Not (Just) the Tariffs: Rethinking Non-Tariff Measures in a Fragmented Global Economy
    (Washington, DC: World Bank, 2025-10-22) Taglioni, Daria; KEE, Hiau Looi
    As tariffs have declined, non-tariff measures (NTMs) have become central to trade policy, especially in high-income countries and regulated sectors like food and green technologies. Although NTMs may serve legitimate goals, they could also sort countries and firms into or out of markets based on compliance capacity and differences in product mix. Documenting recent advances in the estimation of ad valorem equivalents (AVEs), this paper uncovers new patterns of use and exposure of NTMs. High-income countries rely more heavily on NTMs relative to tariffs, while low- and middle-income countries face steeper AVEs on their exports. Firm-level evidence shows that NTMs disproportionately affect smaller firms, leading to market exit and concentration. Poorly designed NTMs can harm productivity and welfare, while coordinated, capacity-aware use can deliver inclusive outcomes. Policy design, transparency, and diagnostics must evolve to reflect the growing role—and risks—of NTMs in a fragmented global trade landscape.

    Can Production and Trafficking of Illicit Drugs be Reduced or Merely Shifted?
    (World Bank, Washington, DC, 2008-03) Reuter, Peter
    The production of cocaine and heroin, the two most important drugs economically, has been concentrated in a small number of poor nations for 25 years. A slightly larger number of developing nations have been affected by large-scale trafficking in these two drugs. This paper reviews what is known about drug control programs and considers non-traditional options. The usual array of programs for suppressing drug problems, enforcement, treatment, harm reduction and prevention have been assessed almost exclusively in wealthy nations. Although treatment has been shown to be cost-effective, it is of minimal relevance for reducing the drug problems of nations such as Afghanistan, Colombia, Mexico or Tajikistan, which are primarily harmed by production and trafficking rather than consumption. Efforts to reduce drug production and trafficking have not been subject to systematic evaluation but the best interpretation of the available evidence is that they have had minimal effect on the quantities produced or trafficked. It is reasonable to conclude that international drug control efforts can do more to affect where these drugs are produced rather than the quantity. If that is the case, and given that spreading a specific level of production or trafficking to more rather than fewer nations probably decreases global welfare, it may be appropriate to consider a less aggressive stance to current producers and to make strategic decisions about the location of an industry producing a global bad.

    The Development Impact of the Illegality of Drug Trade
    (World Bank, Washington, DC, 2008-02) Keefer, Philip; Loayza, Norman V.; Soares, Rodrigo R.
    This paper reviews the unintended consequences of the war on drugs, particularly for developing countries, and weighs them against the evidence regarding the efficacy of prohibition to curb drug use and trade. It reviews the available evidence and presents new results that indicate that prohibition has limited effects on drug prevalence and prices, most likely indicating a combination of inelastic drug demand (due to its addictive properties) and elastic supply responses (due to black markets). This should turn the focus to the unintended consequences of drug prohibition. First, the large demand for drugs, particularly in developed countries, generates the possibility of massive profits to potential drug providers. This leads to the formation of organized crime groups, which use violence and corruption as their means of survival and expansion and which, in severe cases, challenge the state and seriously compromise public stability and safety. Second, prohibition and its derived illegal market impose greater costs on farmers than on drug traffickers. In many instances, this entails the transfer of wealth from poor peasants to rich (and ruthless) traders. Third, criminalization can exacerbate the net health effects of drug use. These consequences are so pernicious that they call for a fundamental review of drug policy around the world.

    Trafficking and Fragility in West Africa
    (World Bank, Washington, DC, 2015) Dechery, Côme; Ralston, Laura
    Trafficking is an emerging concern in West Africa that is gaining increasing attention from the international community. This paper examines the relationship between trafficking and fragility in the region through a meta-analysis of existing knowledge and data on the subject. Given the scope of this paper, we will not attempt to provide any primary empirical or qualitative analysis, but instead focus on offering a comprehensive, unbiased overview of the recent policy and academic literature on the subject, which we hope will assist development practitioners working in the region and help the World Bank identify possible programmatic responses. The authors start this paper by defining trafficking to frame our analysis, and then provide an overview of the trafficking economy across the region. Next, authors outline the potential channels between trafficking and fragility, discussing the actors involved (organized criminal groups, rebels, local or national level politicians, the military, and civilians) and their relevance to specific countries. Finally, the authors present our suggestions on possible policy and programmatic responses, based on identifying both regional and external dimensions to the problems.

    Drug Trafficking and Violence in Central America and Beyond
    (World Bank, Washington, DC, 2011-04) Demombynes, Gabriel
    This paper examines the relationship between narcotics trafficking and violence in Central America. The first part of the paper addresses particular questions posed for the 2011 World Development Report and examines several competing hypothesis on the drivers of crime in Central America. A key finding is that areas exposed to intense narcotics trafficking in Central America suffer from higher homicide rates. Drug trafficking has corrupted state institutions, which have been overwhelmed by the resources deployed by trafficking organizations. The second part of the paper reviews the reasons drug trafficking and anti trafficking enforcement are associated with violence in general and consider policy options.

    The Historical Foundations of the Narcotic Drug Control Regime
    (World Bank, Washington, DC, 2008-03) Buxton, Julia
    This paper outlines the institutional history of the international narcotic drug control regime. It details the evolution of the control system, from its foundations at the beginning of the twentieth century - a period of mass, unregulated narcotic drug use - to the current period. The paper argues that the contemporary control model is ill-positioned to address the dynamic and rapidly changing nature of the global narcotics trade. The persistence of anachronistic guiding first principles, specifically the utopian idea of prohibition, is identified as the key impediment to the adoption of a more humane and effective policy approach. But while there is growing pressure for a revision of founding ideas, this is not supported by a host of powerful actors that includes the United States.

    Digital Africa
    (Washington, DC: World Bank, 2023-03-13) Begazo, Tania; Dutz, Mark Andrew; Blimpo, Moussa
    All African countries need better and more jobs for their growing populations. "Digital Africa: Technological Transformation for Jobs" shows that broader use of productivity-enhancing, digital technologies by enterprises and households is imperative to generate such jobs, including for lower-skilled people. At the same time, it can support not only countries’ short-term objective of postpandemic economic recovery but also their vision of economic transformation with more inclusive growth. These outcomes are not automatic, however. Mobile internet availability has increased throughout the continent in recent years, but Africa’s uptake gap is the highest in the world. Areas with at least 3G mobile internet service now cover 84 percent of Africa’s population, but only 22 percent uses such services. And the average African business lags in the use of smartphones and computers as well as more sophisticated digital technologies that catalyze further productivity gains. Two issues explain the usage gap: affordability of these new technologies and willingness to use them. For the 40 percent of Africans below the extreme poverty line, mobile data plans alone would cost one-third of their incomes—in addition to the price of access devices, apps, and electricity. Data plans for small- and medium-size businesses are also more expensive than in other regions. Moreover, shortcomings in the quality of internet services—and in the supply of attractive, skills-appropriate apps that promote entrepreneurship and raise earnings—dampen people’s willingness to use them. For those countries already using these technologies, the development payoffs are significant. New empirical studies for this report add to the rapidly growing evidence that mobile internet availability directly raises enterprise productivity, increases jobs, and reduces poverty throughout Africa. To realize these and other benefits more widely, Africa’s countries must implement complementary and mutually reinforcing policies to strengthen both consumers’ ability to pay and willingness to use digital technologies. These interventions must prioritize productive use to generate large numbers of inclusive jobs in a region poised to benefit from a massive, youthful workforce—one projected to become the world’s largest by the end of this century.

    Compendium of International and National Legal Frameworks on Sexual Harassment in the Workplace
    (World Bank, Washington, DC, 2019-12) World Bank
    Sexual Harassment in the Workplace (SHWP) is a universal and widespread phenomenon that affects millions of women of all social strata worldwide. It is an endemic issue that has gained increased visibility and attention since the beginning of the “#MeToo” movement. In this Compendium on International and National Legal Frameworks on Sexual Harassment in the Workplace (the “Compendium”), SHWP is understood as a gender-specific form of violence, commonly directed against women and occurring in employment or the workplace. It includes requests for sexual favors, unwelcome sexual advances or other sexual conduct, whether physical or verbal, which involves a “quid pro quo” aspect (e.g. request for sexual favors used to make employment decisions) and/or creates an intimidating, hostile, toxic, humiliating or offensive working environment. As one of the pervasive expressions of gender-based violence, it reflects discriminatory social norms, stereotypes, impunity and gender inequality. SHWP is viewed as a development challenge and has high economic and social costs. Despite its serious implications for women, employers and society at large, the behavior is widely accepted and minimized. The Compendium provides a survey of the key international and regional instruments as well as national legislation as they relate to SHWP.

    Doing Business 2014 : Understanding Regulations for Small and Medium-Size Enterprises
    (Washington, DC: World Bank Group, 2013-10-28) World Bank; International Finance Corporation
    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.

    World Development Report 2006
    (Washington, DC, 2005) World Bank
    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.

    Classroom Assessment to Support Foundational Literacy
    (Washington, DC: World Bank, 2025-03-21) Luna-Bazaldua, Diego; Levin, Victoria; Liberman, Julia; Gala, Priyal Mukesh
    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.
