Edukasi Jajanan Sehat dan Bergizi bagi Siswa SD melalui Simulasi Interaktif dan Deteksi Bahan Berbahaya
No full textMasa sekolah dasar merupakan fase penting dalam pembentukan kebiasaan hidup sehat, termasuk pemilihan jajanan yang berdampak pada kesehatan jangka panjang. Namun, jajanan sekolah masih menghadapi persoalan dari sisi gizi maupun keamanan pangan karena adanya penggunaan bahan tambahan berbahaya. Kegiatan pengabdian masyarakat ini bertujuan meningkatkan pengetahuan, sikap, dan praktik siswa dalam memilih jajanan sehat, aman, dan bergizi. Program dilaksanakan di SDN 027 Samarinda Ulu dengan melibatkan 48 siswa kelas VI dan 2 guru melalui empat tahapan, yaitu sosialisasi, pelatihan, penerapan media edukatif, serta pendampingan dan evaluasi. Media yang digunakan meliputi leaflet, booklet, dan video animasi interaktif, sedangkan evaluasi dilakukan melalui pre-test, post-test, observasi, dan wawancara. Hasil kegiatan menunjukkan adanya peningkatan signifikan pada pengetahuan, sikap, dan praktik siswa, dengan perubahan terbesar pada aspek praktik. Siswa mulai lebih selektif dalam memilih jajanan, mengurangi konsumsi makanan berpengawet, serta sebagian sudah membawa bekal dari rumah. Program ini terbukti efektif mendorong literasi pangan sejak dini dan mendukung terciptanya lingkungan sekolah sehat. Meski demikian, tantangan berupa keterlibatan orang tua yang masih terbatas serta daya tarik jajanan tidak sehat tetap perlu mendapat perhatian melalui kolaborasi lintas pihak dan dukungan kebijakan sekolah agar dampaknya berkelanjutan
Financial Risks and Opportunities : Establishing Effective National and Regional Risk Financing Mechanisms for Brazil - Financial and Private Sector Development Policies for Fostering Sustainable Growth in Brazil
No full textThis report, developed under the World Bank’s technical assistance program “Financial and Private Sector Development Policies for Fostering Sustainable Growth in Brazil,” examines strategies for strengthening disaster risk financing in response to floods. It provides an overview of federal public expenditure on disaster risk, assesses financial implications of future flood events through probabilistic analysis under two climate scenarios, and explores options for using financial instruments to ensure predictable funding. Building on reforms introduced after the 2011 Rio de Janeiro floods, the report highlights opportunities to improve budgetary processes and incentivize risk transfer to the private sector at state and municipal levels. With climate change driving increased frequency and severity of extreme weather events, Brazil faces heightened exposure to hydrological risks, substantial fiscal pressures, economic disruption, and human losses. The findings underscore the need for strategic resource allocation and robust risk financing mechanisms to enhance resilience and mitigate future impact

Willingness-to-Pay for Emerging Technologies: A Study of Hydrogen Demand in the Ammonia Industry
No full textThis study introduces a novel quantitative method to assess the willingness to pay for emerging technologies, such as hydrogen, as substitutes for fossil fuels in industrial production. A three-step framework is developed to derive the willingness-to-pay function based on industrial competition and market entry theory, relying exclusively on pre-entry market information. First, a system of equations is specified linking domestic consumption, production, and prices to fossil input prices, which proxy marginal production costs. Second, the market equilibrium parameters required for numerical willingness-to-pay estimation are empirically estimated using industry-level data. Third, an industrial competition model incorporating entry by producers adopting new technology is constructed, allowing willingness to pay to be expressed as a function of conventional input costs, operational efficiency, and demand conditions. The framework is applied to hydrogen use in ammonia production, using consumption and trade data from 2000–24 for 16 major fertilizer-producing countries across four regions. The results highlight substantial cross-country heterogeneity, a binding hydrogen price threshold for large-scale adoption, and the limited effectiveness of carbon policies in accelerating hydrogen uptake
The Role of Credible Mitigation Measures in Building Citizen Trust for Subsidy Reforms: Lessons from Angola’s Public Opinion Survey
No full textThis study explores public opinion for reducing fossil fuel subsidies in Angola, identifies strategies that can shift public opinion, and analyzes variations in support based on respondents’ area of residency and gender. It uses data from a survey of 598 respondents and focus groups involving 30 individuals, conducted in 2024 after the first phase of a fuel subsidy reform. The findings suggest that this initial phase of reforms had significant negative effects on households’ well-being. Support for subsidy reform is low among respondents, around 30 percent, but bundling reforms with mitigation measures is expected to increase public support significantly to nearly 90 percent. This happens when the government intends to use the savings to invest in public infrastructure, stimulate the economy, create jobs, improve access to public services, and provide targeted cash transfers. Mitigation measures appear particularly effective in increasing support among female respondents and those residing in rural areas. The findings also reveal limited public awareness of fuel subsidy policies, low levels of trust in the government, and lack of clarity in government communications. These insights underscore the importance of careful planning, transparent communication, and a comprehensive mitigation package that addresses both short- and longer-term needs to build public support and ensure successful implementation of fuel subsidy reforms
Institutional Capacity for Policy Implementation: An Analytical Framework
No full textState capacity is an important prerequisite for policy implementation, yet at the country level it is difficult to measure, assess, and reform. This paper proposes a focus on institutional capacity: the ability of public institutions to implement the specific policy mandates for which they are responsible. Based on a review of existing literature, the paper defines the different dimensions that compose institutional capacity and groups them into two cross-cutting categories: organizational dimensions (personnel, financial resources, information systems, and management practices) and governance dimensions (transparency, independence, and accountability). The paper proposes measures for organizational and governance dimensions using existing data, shows intra-institutional variation of these measures within countries, and discusses how new data could be collected for better measurement of these concepts. Finally, the paper illustrates how the framework can be used to diagnose the sources of common problems related to weak policy implementation
Demand Shocks in Equity Markets and Firm Responses
No full textThis paper examines how shifts in investor demand influence
firm financing and investment decisions. For identification,
the paper exploits a large-scale MSCI methodological
reform that mechanically redefined the stock weights in
major international equity benchmark indexes, changing
the portfolio allocation of 2,508 firms across 49 countries.
Because benchmark-tracking investors closely follow these
indexes, the rebalancing constituted a clean shock to equity
demand. The results show that portfolio rebalancing by
benchmark-tracking investors generated significant capital
inflows and outflows at the firm level. Firms experiencing
larger inflows increased equity issuance, even more so debt
financing, and real investment. The paper complements the
empirical analysis with a simple model of firm financing
in which a decline in the cost of equity increases the value
of equity and relaxes borrowing constraints. Higher equity
valuations allow firms to expand borrowing even without
issuing substantial new equity, so debt financing responds
more strongly than equity issuance
