Governance and Economics of Desalination and Reuse
No full textThe global challenge of water scarcity is intensified by factors such as population growth, rainfall variability, and water stress, with climate change further affecting the water cycle and impacting food, energy, urban, and environmental systems. In response, there is a global increase in investments in desalination and water reclamation infrastructure. Countries adopting unconventional water resources may need to adapt their institutional structures and management models, potentially involving the private sector. The World Bank has developed a knowledge series comprising five volumes to assist sector authorities in sustainably mainstreaming unconventional water sources. These volumes focus on the following areas: 1) Policies and Regulations, 2) Sector-Level Governance Models, 3) Economic Appraisal, 4) Finance and Delivery Models, and 5) Management Models to Serve Remote Poor Areas
Evidence from Changes in the Minimum Working Age
No full textThis paper investigates the effect of
a unique child labor ban regulation on employment and school
enrollment. The ban, implemented in Mexico in 2015,
increased the minimum working age from 14 to 15, introduced
restrictions to employing underage individuals, and imposed
stricter penalties for violation of the law. Our
identification strategy relies on a DiD approach that
exploits the date of birth as a natural cutoff to assign
individuals into treatment and control groups. The ban led
to a decrease in the probability of working by 1.2
percentage points, resembling a 16 percent decrease relative
to the pre-reform mean, and an increase in the likelihood of
being enrolled in school by 2.2 percentage points for the
treatment group. These results are driven by reduced
employment in paid work and the manufacturing and services
sectors. The effects have been persistent for several years
after the ban
Redefining the Role of State-Owned Enterprises in Libya
No full textIn 2024, Libya’s economic performance reflects the persistent challenges of hydrocarbon dependency compared against nascent signs of broader recovery. The economy recorded a contraction of 0.6 percent for the year, driven primarily by a decline in oil GDP of 6 percent amid political and institutional disruptions that originated from the Central Bank of Libya (CBL) crisis in August. However, non-oil GDP growth of 7.5 percent, supported by robust private and public consumption, partially offset the decline. The weak overall performance highlights the critical reliance on the oil sector while underscores the limited capacity of non-oil sectors to fully mitigate hydrocarbon-related volatility absent deeper structural reforms. The Libyan economy is expected to rebound in 2025 primarily driven by the expansion of oil sector activities. The CBL’s official data offers an incomplete view of Libya’s fiscal health, hindering a full economic assessment. The data published by the CBL on a monthly basis includes Government of National Unity budgetary and extra-budgetary expenditures, including the National Oil Company and General Electricity Company, but underestimates oil revenues and fuel subsidies as a result of the oil-for-fuel swap mechanism implemented since November 2021. It also omits Government of National Stability public spending, complicating accurate fiscal position analysis. This incomplete financial picture challenges effective policymaking and risks further instability in Libya’s fragile economy. The Special Focus Section Redefining the Role of State-Owned Enterprises in Libya examines the State-Owned Enterprises (SOEs) landscape in Libya’s economy, delving into their impact on fiscal sustainability and private sector growth, while drawing comparisons with structural and aspirational peers. It relies on new analysis using the World Bank’s Business of the State (BOS) database and reveals a vast network of nearly 190 Libyan SOEs spanning strategic and competitive sectors, including oil and gas, finance, utilities, transport, manufacturing, and tourism. The analysis provides, for the first time, a clearer picture of the scale, sectoral footprint, and governance structure of SOEs in Libya, confirming the outsized presence of the state across the economy. The analysis surfaces critical fiscal risks, inefficiencies, lack of transparency and market distortions
Knowledge, Data, and Information
No full textAfrica has significant potential to improve its climate-smart sustainable development by focusing on the Blue Economy. However, efforts to reach this potential are stymied by poor access to relevant data and knowledge due to inadequate historical investments in technology and institutional capacity for modernization. Today, many opportunities exist to leapfrog traditional development paths by leveraging a new range of technologies. BlueTech refers to the innovative use of emerging technologies to scale up the development impact of the Blue Economy, while managing associated trade-offs. These technologies can potentially accelerate the expansion of the Blue Economy, but only if African countries invest in enabling infrastructure, capacity, and services to strengthen their technological innovation ecosystem. A robust technological backbone will better harness the power of the cloud, e-package data, and technological knowledge to enable new ways to collect, analyze, and share data, making it more accessible and usable. At the same time, it will facilitate the collaborative development of harmonized systems to generate insights into and support decisions relating to the Blue Economy
Navigating Fiscal Realities for Equitable Growth in Georgia
No full textGeorgia has made impressive economic progress over the past two decades, achieving strong and resilient economic growth and development despite numerous external and domestic shocks. This Fiscal Incidence Analysis (FIA) report serves as a baseline for evaluating current fiscal policy and potential policy reforms to enhance fiscal equity and sustainability. The Commitment to Equity (CEQ) methodology helps understand which population subgroups benefit the most from public expenditures and which subgroups are paying the taxes that finance those expenditures. It traces changes in the distribution of household incomes from market income (before taxes and transfers) to final income, identifying changes in income inequality and poverty attributable to different fiscal policy interventions such as taxes, transfers, and social expenditures. The equity aspect of fiscal policy is critical to informing Sustainable Development Goals Indicator 10.4.2, which measures the redistributive impact of fiscal policy. The FIA helps identify spending priorities based on their contributions to reducing poverty and inequality and examines how fiscal space can be created without increasing the burden on poor and vulnerable households
Making Digital Work for People and Jobs
No full textDigital technology also brings real risks. Millions still lack access
to affordable data and devices or the skills to use them. Women
and low-income groups face the steepest digital barriers. Many
countries still rely on outdated, fragmented systems that isolate
users, replicate costs, and fail to protect data. And with AI
developing at breakneck speed, often more rapidly than society
can adapt, the risks of misuse, exclusion, or harm are rising.
This policy note sets out four priority actions to help realize the
promise of digital technology for human development while
managing the risks
Quasi-Experimental Evidence from Sierra Leone
No full textLand disputes are unavoidable and costly in formal courts in contexts with weak property rights and low state capacity. Many countries permit parallel informal dispute-resolution forums to relax the pressure on strained formal courts. This paper studies the extent to which one such forum, Chiefdom Land Committees (CLCs), in Sierra Leone can resolve land disputes. This paper constructs a data set of ligated cases at local courts nationwide. It implements a difference-in-difference design to estimate the effect of the CLCs on land caseload in the formal courts. Contrary to the policy goals, this paper finds that on average, chiefdoms with CLCs have higher land caseload in the formal courts three years on. By adopting the CLCs, chiefdoms plausibly made land issues more salient, but instead of providing final resolutions, CLCs are conduits for formalizing land disputes
