Abstract
The authors designed and tested a voluntary commitment product to help smokers quit smoking. The product (CARES) offered smokers a savings account in which they deposit funds for six months, after which they take a urine test for nicotine and cotinine. If they pass, their money is returned; otherwise, their money is forfeited to charity. Eleven percent of smokers offered CARES tookup, and smokers randomly offered CARES were 3 percentage points more likely to pass the 6-month test than the control group. More importantly, this effect persisted in surprise tests at 12 months, indicating that CARES produced lasting smoking cessation.

Publication Global Poverty Revisited Using 2021 PPPs and New Data on Consumption(Washington, DC: World Bank, 2025-06-05)Recent improvements in survey methodologies have increased measured consumption in many low- and lower-middle-income countries that now collect a more comprehensive measure of household consumption. Faced with such methodological changes, countries have frequently revised upward their national poverty lines to make them appropriate for the new measures of consumption. This in turn affects the World Bank’s global poverty lines when they are periodically revised. The international poverty line, which is based on the typical poverty line in low-income countries, increases by around 40 percent to $3.00 when the more recent national poverty lines as well as the 2021 purchasing power parities are incorporated. The net impact of the changes in international prices, the poverty line, and new survey data (including new data for India) is an increase in global extreme poverty by some 125 million people in 2022, and a significant shift of poverty away from South Asia and toward Sub-Saharan Africa. The changes at higher poverty lines, which are more relevant to middle-income countries, are mixed.Publication The Economic Value of Weather Forecasts: A Quantitative Systematic Literature Review(Washington, DC: World Bank, 2025-09-10)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.Publication The Marshall Plan: Then and Now(Washington, DC: World Bank, 2025-10-14)This paper is a product of the Development Policy Team, Development Economics. It is part of a larger effort by the World Bank to provide open access to its research and make a contribution to development policy discussions around the world.

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.Publication Geopolitical Risks and Trade(Washington, DC: World Bank, 2025-09-23)This paper studies the impact of geopolitical risks on international trade, using the Geopolitical Risk (GPR) index of Caldara and Iacoviello (2022) and an empirical gravity model. The impact of spikes in geopolitical risk on trade is negative, strong, and heterogeneous across sectors. The findings show that increases in geopolitical risk reduce trade by about 30 to 40 percent. These effects are equivalent to an increase of global tariffs of up to 14 percent. Services trade is most vulnerable to geopolitical risks, followed by agriculture, and the impact on manufacturing trade is moderate. These negative effects are partially mitigated by cultural and geographic proximity, as well as by the presence of trade agreements.

Publication Tobacco Control in Brazil(World Bank, Washington, DC, 2007-08)The objective of this study was to assess the smoking situation in Brazil, and the role of the tobacco control program, and compare it to experience in other countries. The study assessed key trends in smoking rates and lung cancer in Brazil, and reviewed price and non-price interventions. A discussion of fiscal instruments and smuggling is also included in this report. This study aimed at further evaluating the smoking situation in Brazil, the role of the tobacco control program in the country, and compares it to global best practice and experience in other countries. The study report is structured into three main parts: in the first chapter, trends in smoking prevalence, consumption, and cigarette expenditures in Brazil are reviewed, including the illegal market; in the second chapter, trends in lung cancer mortality and health care costs of smoking-related diseases in the country are analyzed; in the third chapter, non-price and price interventions are reviewed, including those taken by the Brazil tobacco control program, as well as the impact increases in cigarette prices and taxes would have on smoking prevalence and tax revenue. The report concludes with recommendations for further action to protect the Brazilian population from premature death and disease caused by smoking, and to reverse the negative impact of smoking on public expenditures.Publication Progression of Tobacco Control Policies : Lessons from the United States and Implications for Global Action(World Bank, Washington, DC, 2008-05)This paper examines the historical experience of tobacco control in the last five decades and shares important lessons of public health interventions to inform current and future tobacco control programs in other countries. The paper is divided into four parts. The first part gives an overview of the political economy, principal influences and interventions in tobacco control in the United States. It stresses the importance of information shocks and the role played by grassroots organizations. The current situation of tobacco control in the United States is further discussed in the second part, with emphasis on the economic case that led to litigation, as well as the response of the industry and the States. The third part focuses on the present efforts of multilaterals like the World Bank, technical United Nation (UN) agencies such as the World Health Organization, in the context of the new global governance structure: the Framework Convention on Tobacco Control (FCTC). The last section discusses lessons learned and provides recommendations for comprehensive tobacco control programs.Publication Smoke-Free Workplaces(Washington, DC, 2002-07)Smoking harms the health of smokers and those around them. Smokers are at far higher risks of strokes, heart attacks and other cardiovascular diseases; cancers of the lungs, mouth, larynx, bladder, pancreas, kidneys and stomach; emphysema, bronchitis, and tuberculosis. These diseases cause serious illness, disability and premature death. Tobacco causes 4 million deaths worldwide each year, and the numbers are rising fast. Tobacco smoke also harms non-smokers exposed to so-called second-hand smoke or environmental tobacco smoke (ETS). In addition to smell and irritation to eyes, ETS exposure increases the risk of lung cancer and cardio-vascular and respiratory diseases. ETS exposure is common in workplaces. In 1996, an estimated 130 million adult non-smokers in China were exposed to workplace ETS. In the UK in 1999, more than 3 million non-smokers were continuously or frequently exposed to tobacco smoke at work. In France, where there are laws restricting smoking in public spaces, 40 percent of employees are still exposed to ETS. ETS can interact with chemicals and radiation in workplaces to produce an additive or multiplicative effect and increase significantly the risk of many occupational diseases. In some countries, employers have a legal responsibility to protect the health of their employees. Smoke-free workplaces can reduce employers' legal liability, create safer working environments, improve workers' health and enhance corporate image. [Revised April 2011]Publication Towards a Political Economy of Tobacco Control in Low- and Middle-Income Countries(World Bank, Washington, DC, 2009-08)This study provides the basis for constructing a political economy of tobacco control in low- and middle-income countries (LMICs). The authors first undertook a literature review of tobacco control in LMICs to explore the forces that oppose the adoption, implementation, and enforcement of tobacco control strategies. The authors then used the sources collected to conduct a stakeholder analysis, as a first step in constructing a political economy of tobacco control in LMICs. The authors focused primarily at the international level because of the dominant role of transnational tobacco companies (TTCs). The author's review of the literature suggests four broad conclusions. First, a political economy approach has been applied only rarely as a formal analytical methodology in the literature on the tobacco control in LMICs. Second, even when the term "political economy" was used in a document, the paper typically did not explicitly conduct this kind of analysis and did not directly consider political strategies for advancing tobacco control. Third, translating the framework convention on tobacco control into tobacco use reductions at the national level is likely to require national-level political economy analyses to define political strategies appropriate to the particular national setting. Fourth, tobacco control's present and past is well documented, but analyses of future scenarios have focused on projections of health consequences and smoking trends. How TTCs will try to grow in the future has not been adequately addressed in the literature.Publication Tobacco Control(Washington, DC, 2003-07)The note looks at tobacco from the health perspective, and at how to reduce its use, since smoking is becoming the single biggest cause of death worldwide, particularly affecting the developing countries, where most of the world's smokers live. It thus looks at the correlation between smoking and poverty, stating smoking prevalence tends to be higher among men with less education, and with lower incomes, hence bearing greater health risks. Because of the highly addictive factor of nicotine, smoking initiation should be discouraged, persuading particularly the young, in an aim to reduce disease, and death resulting from tobacco use. Towards this effort, the World Health Organization, the Bank, and other agencies are becoming partners to improve health, and to this end, an International Framework Convention on Tobacco Control is being negotiated, while further efforts are led by nongovernmental organizations, and nationally particularly as taxation is the most effective way to reduce tobacco use. The note also outlines evidence that results are best achieved within comprehensive measures to reduce tobacco use; that job losses in tobacco farming, and manufacturing, are to be offset by jobs in other sectors, responsive to changed expenditure patterns; and, that while most measures to reduce tobacco supply are ineffective, smuggling control is however, the key supply-side measure to pursue.

Publication Governance Matters VIII : Aggregate and Individual Governance Indicators 1996–2008(2009-06-01)This paper reports on the 2009 update of the Worldwide Governance Indicators (WGI) research project, covering 212 countries and territories and measuring six dimensions of governance between 1996 and 2008: Voice and Accountability, Political Stability and Absence of Violence/Terrorism, Government Effectiveness, Regulatory Quality, Rule of Law, and Control of Corruption. These aggregate indicators are based on hundreds of specific and disaggregated individual variables measuring various dimensions of governance, taken from 35 data sources provided by 33 different organizations. The data reflect the views on governance of public sector, private sector and NGO experts, as well as thousands of citizen and firm survey respondents worldwide. The authors also explicitly report the margins of error accompanying each country estimate. These reflect the inherent difficulties in measuring governance using any kind of data. They find that even after taking margins of error into account, the WGI permit meaningful cross-country comparisons as well as monitoring progress over time. The aggregate indicators, together with the disaggregated underlying indicators, are available at www.govindicators.org.Publication Government Matters III : Governance Indicators for 1996-2002(World Bank, Washington, DC, 2003-08)The authors present estimates of six dimensions of governance covering 199 countries and territories for four time periods: 1996, 1998, 2000, and 2002. These indicators are based on several hundred individual variables measuring perceptions of governance, drawn from 25 separate data sources constructed by 18 different organizations. The authors assign these individual measures of governance to categories capturing key dimensions of governance and use an unobserved components model to construct six aggregate governance indicators in each of the four periods. They present the point estimates of the dimensions of governance as well as the margins of errors for each country for the four periods. The governance indicators reported here are an update and expansion of previous research work on indicators initiated in 1998 (Kaufmann, Kraay, and Zoido-Lobat 1999a,b and 2002). The authors also address various methodological issues, including the interpretation and use of the data given the estimated margins of errors.Publication Design Thinking for Social Innovation(2010-07)Designers have traditionally focused on enchancing the look and functionality of products.Publication Breaking the Conflict Trap : Civil War and Development Policy(Washington, DC: World Bank and Oxford University Press, 2003)Most wars are now civil wars. Even though international wars attract enormous global attention, they have become infrequent and brief. Civil wars usually attract less attention, but they have become increasingly common and typically go on for years. This report argues that civil war is now an important issue for development. War retards development, but conversely, development retards war. This double causation gives rise to virtuous and vicious circles. Where development succeeds, countries become progressively safer from violent conflict, making subsequent development easier. Where development fails, countries are at high risk of becoming caught in a conflict trap in which war wrecks the economy and increases the risk of further war. The global incidence of civil war is high because the international community has done little to avert it. Inertia is rooted in two beliefs: that we can safely 'let them fight it out among themselves' and that 'nothing can be done' because civil war is driven by ancestral ethnic and religious hatreds. The purpose of this report is to challenge these beliefs.Publication Governance Matters IV : Governance Indicators for 1996-2004(World Bank, Washington, DC, 2005-06)The authors present the latest update of their aggregate governance indicators, together with new analysis of several issues related to the use of these measures. The governance indicators measure the following six dimensions of governance: (1) voice and accountability; (2) political instability and violence; (3) government effectiveness; (4) regulatory quality; (5) rule of law, and (6) control of corruption. They cover 209 countries and territories for 1996, 1998, 2000, 2002, and 2004. They are based on several hundred individual variables measuring perceptions of governance, drawn from 37 separate data sources constructed by 31 organizations. The authors present estimates of the six dimensions of governance for each period, as well as margins of error capturing the range of likely values for each country. These margins of error are not unique to perceptions-based measures of governance, but are an important feature of all efforts to measure governance, including objective indicators. In fact, the authors give examples of how individual objective measures provide an incomplete picture of even the quite particular dimensions of governance that they are intended to measure. The authors also analyze in detail changes over time in their estimates of governance; provide a framework for assessing the statistical significance of changes in governance; and suggest a simple rule of thumb for identifying statistically significant changes in country governance over time. The ability to identify significant changes in governance over time is much higher for aggregate indicators than for any individual indicator. While the authors find that the quality of governance in a number of countries has changed significantly (in both directions), they also provide evidence suggesting that there are no trends, for better or worse, in global averages of governance. Finally, they interpret the strong observed correlation between income and governance, and argue against recent efforts to apply a discount to governance performance in low-income countries.
