Economic growth in Sao Tome and Principe (STP) has long been driven by an unsustainable reliance on public expenditures, especially grant- and loan-financed public investment. STP needs to turn its smallness into uniqueness to unlock its growth potential. to accomplish this transformation, this image must be matched by a more balanced growth in which the private sector plays a larger role and with a more effective government. Tourism, agriculture, and fisheries could drive the country's transition to a more balanced growth pattern. This Country Economic Memorandum (CEM) highlights six key challenges that STP must overcome as it transitions to a more balanced growth pattern and it offers policy recommendations for addressing each challenge. Accomplishing this rebalancing will require STP to address six key challenges at the macroeconomic, structural, and sectoral level. These include: (i) The twin budget and current-account deficits; (ii) Weak trade connectivity by both air and sea; (iii) Credit constraints caused by a high level of non-performing loans and difficulties enforcing commercial contracts; (iv) Uncertainty surrounding property rights and land tenure; (v) Poor-quality infrastructure, especially in the energy and transportation sector; and (vi) The overexploitation of marine resources.

This review, developed in cooperation with UNICEF, provides Serbia with recommendations to help strengthen its evaluation and assessment system to focus on support for student learning. It will be of interest to Serbia, as well as other countries looking to make more effective use of their evaluation and assessment system to improve quality and equity, and result in better outcomes for all students.

The authors bring new empirical evidence on the impact of the choice of ownership and regulatory regime on firms' productivity and prices paid by consumers. They collect the evidence from a sample of electricity distribution companies in Latin America. The authors rely on estimations of labor and operation and maintenance (O&M) input requirement functions using alternative econometric approaches. Their main conclusions are: 1. Private firms perform better (approximately 30 percent) than public firms. 2. The regulatory regimes matter, so that price-cap regulated firms do better than rate-of-return regulated firms, and firms regulated under hybrid regimes have intermediate performance. 3. Private firms operating under rate of return are at most as efficient as public firms. 4. There is no clear pattern of differences in electricity prices according to the regulatory regime. 5. Final prices fell in general but the drop did not match the productivity gains, implying that the operators and the state share some of the gains in the form of rents and higher tax revenue, respectively.

Although Brazil is the fifth largest country in the world, it has a relatively low number of natural hazards. However, its exposure to natural hazards has increased relative to other countries because of insufficient preventive actions in the past, resulting in more damage from natural hazards to both infrastructure and human lives than countries of comparable size would incur. Brazil faces an increasing risk of natural disasters, in particular floods and landslides. The objective of the study is to strengthen capacity of geohazard disaster resilience of federal highway infrastructure in Brazil through reviewing disaster risk management (DRM) capacity for federal road infrastructure and case studies of applying innovative methodologies for assessing disaster risk and evaluating economic benefits of resilience countermeasures. Although floods and landslides are the most recurrent natural disasters in Brazil, this report focuses on the latter, leaving floods for future studies. This report carefully describes how three innovative methodologies that, if properly applied, could improve the effectiveness of landslide risk management, thus reducing economic and human impacts. The report begins with diagnostics of the institutional capacities of geohazard risk management at the federal government level in Brazil. Chapters 1 and 2 include the backgrounds of natural disasters, road systems, and geohazards on roads in Brazil and a review of the road geohazard risk management with overviews of the following areas: institutional capacity and coordination, system planning, engineering designs, operation and maintenance, nonstructural measures, and contingency programming. Then, Chapters 3 and 4 describe the case study of application of the three innovative DRM assessment methodologies. Finally, Chapter 5 shows the suggestions and recommendations for the next steps.

"Global value chains (GVCs) powered the surge of international trade after 1990 and now account for almost half of all trade. This shift enabled an unprecedented economic convergence: poor countries grew rapidly and began to catch up with richer countries. Since the 2008 global financial crisis, however, the growth of trade has been sluggish and the expansion of GVCs has stalled. Meanwhile, serious threats have emerged to the model of trade-led growth. New technologies could draw production closer to the consumer and reduce the demand for labor. And trade conflicts among large countries could lead to a retrenchment or a segmentation of GVCs. World Development Report 2020: Trading for Development in the Age of Global Value Chains examines whether there is still a path to development through GVCs and trade. It concludes that technological change is, at this stage, more a boon than a curse. GVCs can continue to boost growth, create better jobs, and reduce poverty provided that developing countries implement deeper reforms to promote GVC participation; industrial countries pursue open, predictable policies; and all countries revive multilateral cooperation"--

This paper presents a meta-analysis of the infrastructure research done over more than three decades, using a database of close to a thousand estimates from 201 papers conducted between 1983-2022, reporting outcome elasticities. The analysis casts a wide net to include the transport, energy, and digital or information and communications technology sectors and the whole set of outcomes covered in the literature, including output, employment and wages, inequality and poverty, trade, education and health, population, and environmental aspects. The results allow for an update of the underlying parameters of interest, the "true" underlying infrastructure elasticities, accounting for publication bias, as well as for heterogeneity stemming from both study design and context, with a particular focus on policy relevant subsectors and developing countries.
