Abstract
Energy poverty has gained attention in the context of increasing energy prices and the recent energy crisis in Europe. However, measuring energy poverty and characterizing the energy poor are challenging, given that expenditure surveys (household budget surveys) often need more information to characterize the energy poor. Additionally, there is no consensus on how to measure and monitor energy poverty. It is also unknown how and why it differs from income poverty. While income poverty relies on a well-defined poverty line, energy poverty does not have a clearly defined energy poverty line that indicates the minimum energy necessary for satisfying basic needs. In addition, monetary poverty and other welfare measures are measured with income in EU countries using the European Survey of Income and Living Conditions. Therefore, it is not straightforward to characterize energy affordability among the monetary income poor or to estimate the overlap between official income poverty and energy poverty. This paper explores statistical matching as a potential strategy to overcome these data challenges in the context of Bulgaria. Via data fusion, a unique dataset is generated that contains information on energy spending shares, income-based indicators of poverty and inequality, and additional variables on households' living conditions and welfare. For this purpose, the paper first generates a harmonized dataset, which consists of the European Survey of Income and Living Conditions and household budget survey data. It then employs different imputation models and chooses the best-performing one to impute energy spending shares into data. Based on the resulting dataset, it overlays energy poverty with monetary poverty. The findings show that a large share of the energy poor is not income poor, calling for differentiated policy measures to tackle energy poverty. Importantly, these findings depend on the underlying definition of energy poverty. This paper contributes to a growing body of literature exploring the potential of statistical matching to improve the current data environment in the European Union.

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 Macroeconomic Implications of Climate Change Impacts and Adaptation Options(Washington, DC: World Bank, 2025-05-29)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.Publication Labor Demand in the Age of Generative AI: Early Evidence from the U.S. Job Posting Data(Washington, DC: World Bank, 2025-11-18)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.Publication The Lasting Effects of Working while in School(Washington, DC: World Bank, 2025-08-18)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.Publication It’s Not (Just) the Tariffs: Rethinking Non-Tariff Measures in a Fragmented Global Economy(Washington, DC: World Bank, 2025-10-22)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.

Publication Statistically Matching Income and Consumption Data(Washington, DC: World Bank, 2024-09-23)To design effective policy instruments that target the energy poor in Romania, it is crucial to understand who the energy poor are. However, these types of analyses are limited by the current data environment. While monetary energy poverty estimates rely on data from expenditure surveys, traditional welfare indicators and detailed information on access to social protection programs form part of the EU-SILC. Samples of both surveys differ; consequently, record linkage of both surveys is impossible. This paper propose an alternative solution to combine information from both surveys, namely statistical matching techniques. It applies several imputation models to impute information on energy spending shares from the HBS into the EU-SILC based on a set of matching variables, compare the performance of these models and apply the best-performing one. Based on the resulting matched dataset, the results show that nearly all the monetary poor are also energy poor, but that a significant additional share of the population in Romania is energy poor. Energy poverty rates are higher at the lower end of the welfare distribution. This result has significant welfare implications.Publication Conceptualizing and Measuring Energy Poverty in Bulgaria(Washington, DC: World Bank, 2024-06-28)Addressing energy poverty has emerged as one of the main challenges for Bulgaria's poverty and social inclusion policy, particularly in the context of the European Green Deal and the current crisis in Ukraine. To tackle the adverse impacts of energy poverty effectively, a crucial initial step involves accurately defining and measuring this issue. Identifying households affected by energy poverty is essential for shaping and implementing targeted policies. This study explores various definitions of energy poverty within the Bulgarian context by (1) systematically reviewing current methodologies and measures employed in the EU context; (2) assessing the feasibility of implementing these measures in Bulgaria based on data availability, comparing the incidence of energy poverty using alternative measures, and presenting characteristics of energy poverty to inform potential policy instruments; and (3) providing policy recommendations for the measurement and monitoring of energy poverty. The way energy poverty is measured and the overlap with income poverty shape the types of policy solutions perceived to be possible and appropriate to address it. The evaluation supports the need to shift from single indicators to multidimensional approaches in measuring energy poverty. Additionally, enhancing the granularity, quality, and frequency of expenditure and income surveys can contribute to easier operationalization of these concepts and a better understanding of the demographics of energy poverty. The study proposes exploring alternative data generation methods, such as smart meters, further to enhance insights into the dynamics of energy poverty.Publication Soaring Food Prices Threaten Recent Economic Gains in the EU(Washington, DC: World Bank, 2025-07-02)The surge in food prices following the 2021 economic rebound has become a significant concern for households, particularly low-income ones, in Bulgaria, Croatia, Poland, and Romania. Food price inflation, which surpasses general inflation rates, risks worsening poverty and food insecurity in these countries. This paper explores the distributional impacts of rising food prices and the effectiveness of government response measures. Low-income households, who allocate a larger share of their income to food, are disproportionately affected and are struggling to cope with unexpected expenses, leading to increased difficulties in accessing proper nutrition. Simulations indicate that rising food prices contribute to higher poverty rates and greater income inequality, especially among vulnerable populations. They also suggest that the main poverty-targeted social assistance schemes offer critical support for the extreme poor, but expanding both coverage and benefits is vital to shield all at-risk individuals. Targeted policies that balance immediate relief with long-term resilience-building are essential to addressing the challenges posed by escalating food prices.Publication Understanding and Addressing Energy Poverty in Romania(Washington, DC: World Bank, 2024-09-17)Addressing energy poverty is paramount for economic development, given its close connection to income poverty. Research indicates that lower-income households are disproportionately affected by energy price increases. Such households lack the financial means to absorb these shocks, which can lead to decreased overall welfare. This vulnerability can result in households’ refraining from using energy or using less efficient and dirtier technologies and sources, particularly during winter, which poses health risks. Moreover, global evidence suggests that residing in energy-deprived circumstances adversely affects overall well-being, human development, and environmental outcomes. The imperative to measure and address energy poverty in Romania is underscored by the potential development benefits and the European Commission’s prioritization of this issue within the European Just Transition context. This report aims to fill that gap by providing evidence on critical questions about the energy status of Romanian households. The report focuses on four key topics, relying on existing official household surveys and new qualitative and quantitative data collected in June–July 2023, with the aim of providing an updated snapshot of energy vulnerability among Romanian households.Publication Tax Compliance in Romania(Washington, DC: World Bank, 2024-10-07)This paper uses statistical matching techniques to assess tax compliance and underreporting of labor income in Romania, overall and for different population groups, including among minimum wage workers, to understand the distributional implications and its links with minimum wage policy and design. Understanding the extent and distribution of tax evasion is relevant for enhancing domestic tax capacity, its redistributive impacts, and the links with social policy, including minimum wage policy. Estimating the average underreporting of income is challenging due to the significant underrepresentation of top incomes in survey data. After censoring, the average underreporting of income is 6 percent. When looking at the distribution of tax evasion, the analysis also shows significant underreporting of income in the bottom half of the income distribution. The results show that tax-reported income at the median of the income distribution equals only 90 percent of the true (survey) income, and at the 25th percentile, this share is 83 percent. Women are more tax compliant than men. Tax compliance varies across sectors of the economy, regions of the country, and demographic groups. Transport, construction, and food and accommodation are the sectors of the economy with the lowest tax compliance. The underreporting of income results in lower fiscal capacity for the country and may also lower the efficiency of means-tested social assistance. The underreporting of income significantly increases the share of minimum wage earners, which may impact the minimum wage policy.

Publication Lebanon Economic Monitor, Fall 2022(Washington, DC, 2022-11)The economy continues to contract, albeit at a somewhat slower pace. Public finances improved in 2021, but only because spending collapsed faster than revenue generation. Testament to the continued atrophy of Lebanon’s economy, the Lebanese Pound continues to depreciate sharply. The sharp deterioration in the currency continues to drive surging inflation, in triple digits since July 2020, impacting the poor and vulnerable the most. An unprecedented institutional vacuum will likely further delay any agreement on crisis resolution and much needed reforms; this includes prior actions as part of the April 2022 International Monetary Fund (IMF) staff-level agreement (SLA). Divergent views among key stakeholders on how to distribute the financial losses remains the main bottleneck for reaching an agreement on a comprehensive reform agenda. Lebanon needs to urgently adopt a domestic, equitable, and comprehensive solution that is predicated on: (i) addressing upfront the balance sheet impairments, (ii) restoring liquidity, and (iii) adhering to sound global practices of bail-in solutions based on a hierarchy of creditors (starting with banks’ shareholders) that protects small depositors.Publication Digital Africa(Washington, DC: World Bank, 2023-03-13)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.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 Argentina Country Climate and Development Report(World Bank, Washington, DC, 2022-11)The Argentina Country Climate and Development Report (CCDR) explores opportunities and identifies trade-offs for aligning Argentina’s growth and poverty reduction policies with its commitments on, and its ability to withstand, climate change. It assesses how the country can: reduce its vulnerability to climate shocks through targeted public and private investments and adequation of social protection. The report also shows how Argentina can seize the benefits of a global decarbonization path to sustain a more robust economic growth through further development of Argentina’s potential for renewable energy, energy efficiency actions, the lithium value chain, as well as climate-smart agriculture (and land use) options. Given Argentina’s context, this CCDR focuses on win-win policies and investments, which have large co-benefits or can contribute to raising the country’s growth while helping to adapt the economy, also considering how human capital actions can accompany a just transition.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.
