This paper makes the case for greater transparency of investment incentives and explores how governments can enhance transparency of these measures, notably for investment facilitation purposes. It proposes three overarching principles of transparency that can be used to better inform policy design: availability, accessibility and clarity of information. It also sets out a framework and typology to understand the scope of incentives offered in a country and identify what information could support transparency, drawing on data on the use and level of transparency of incentives (including tax, financial and in-kind benefits) in a sample of 15 developing economies.

Fiscal equalisation and regional development policies have often been perceived as separate policy fields. As a result, little is known about their potential interactions and implications for economic growth and welfare. This working paper reviews the two policies, explores the potential for enhanced synergies between the two, and proposes a theoretical framework linking them. The latter, which has not been empirically tested yet, posits that if regional development policies are correctly designed and implemented, their success should result in a drop of income disparities. Coupled with good governance practices and a framework that clearly allocates responsibilities among levels of government, more equal jurisdictions would find it easier to provide similar levels of services with comparable tax rates across the country. Therefore, whilst correctly designed and implemented fiscal equalisation policies remain a tool to patch gaps that may occur due to the shifting variety of revenue potential and spending needs of subnational entities, the need and the size of fiscal equalisation transfers could be significantly reduced if regional development policies in place are effective. This working paper concludes with a discussion on the benefits and challenges of enhancing synergies between the two policies, opening the door for future in-depth research.

This annual publication compiles comparable tax revenue and non-tax revenue statistics for 33 countries in Africa: Botswana, Burkina Faso, Cabo Verde, Cameroon, Chad, the Republic of the Congo, the Democratic Republic of the Congo, Côte d’Ivoire, Egypt, Equatorial Guinea, Eswatini, Gabon, Ghana, Guinea, Kenya, Lesotho, Madagascar, Malawi, Mali, Mauritania, Mauritius, Morocco, Namibia, Niger, Nigeria, Rwanda, Senegal, Seychelles, Sierra Leone, South Africa, Togo, Tunisia and Uganda. The report extends the well-established methodology on the classification of public revenues set out in the OECD Interpretative Guide to African countries, thereby enabling comparison of tax levels and tax structures not only across the continent but also with the OECD, Latin America and the Caribbean, and Asia and the Pacific. Data on African countries presented in this publication are also included in the OECD’s Global Revenue Statistics database, which is a fundamental reference for analysis of domestic resource mobilisation. This edition includes a special feature on the VAT Digital Toolkit for Africa. The publication is jointly undertaken by the OECD Centre for Tax Policy and Administration, the OECD Development Centre, the African Union Commission (AUC) and the African Tax Administration Forum (ATAF), with the financial support of the European Union.

The Philippines has developed their merger control regime quickly and effectively since the Competition Authority was created in 2016, thus establishing a reputed merger control system. This report assesses those important developments and makes policy recommendations to further strengthen the Philippines’ merger control regime based on principles of transparency, integrity and procedural fairness. This, in turn, can help promote and protect competition in the economy, which increases productivity and overall economic performance.

This report explores how institutional investors can apply risk-based due diligence as recommended by the OECD Guidelines for Multinational Enterprises on Responsible Business Conduct and help them prevent and mitigate adverse climate impacts associated with their investee companies on society and the environment. It provides practical recommendations on how to conduct due diligence as a way to connect climate commitments at portfolio level with real-economy impacts and draws on other frameworks and tools for assessing, managing or disclosing climate impacts associated with investments.

Water-related risks are intrinsically linked to both climate and nature challenges and can be closely tied to socio-economic challenges, such as poverty, food security, and domestic and international conflicts. There is increasing evidence that water-related risks are financially material across actors in the financial system, and further still, that there may be important implications for financial stability. However, a review of current practices indicates that these risks are not fully captured by current approaches to assessing risk. This working paper explores how the financial sector understands the concept of financial materiality as a lever for decision making on water-related climate and nature risks. The paper also looks at how regulatory and supervisory guidance considers water in the context of climate and nature risks, and finally how sustainable finance tools and initiatives can support market participants in gaining an improved understanding of water-related risks.

This paper presents a methodological supervisory framework to help central banks and financial supervisors assess biodiversity-related financial risks, impacts and dependencies in the financial sector, including transmission channels for physical and transition risks. This framework is designed to translate biodiversity risks into financial risks. It draws on a previous mapping of existing approaches, while also accounting for broader nature-related financial risks. While acknowledging different national circumstances, this methodological framework is designed to be applicable broadly for central banks, supervisors and commercial banks across different countries.

Carbon lock-in occurs when high-emission infrastructure or assets continue to be used, despite the possibility of substituting them with low-emission alternatives, thereby delaying or preventing the transition to near-zero or zero-emission alternatives. Transition finance, which focuses on the dynamic transformation and decarbonisation of hard-to-abate sectors, frequently faces the issue of carbon lock-in, particularly in considerations of investment feasibility and eligibility. Despite most transition finance approaches incorporating lock-in avoidance as a core principle, existing transition instruments and approaches put in place varying or limited mechanisms to prevent lock-in. Building on the OECD Guidance on Transition Finance, this report takes stock of how carbon lock-in risk is addressed in existing transition finance approaches (such as taxonomies, roadmaps, or guidance), financial instruments, and relevant public and private investment frameworks and methodologies. The report provides good practices on the integration of credible mechanisms to prevent carbon lock-in, address greenwashing risks and build confidence in the market. It can inform both public and private actors in the development of transition finance approaches, standards for green, transition and sustainability-linked debt, frameworks for corporate transition plans, or broader climate-related disclosure frameworks.
