Regional Trade Agreements (RTAs) have become the major route for countries to reduce trade barriers and open new markets. To fully assess the current state of market opening for agricultural products and examine the potential impacts of RTAs, access to up-to-date and consistent information on preferential tariffs is crucial. There are multiple databases that collect information on preferential tariffs; however, it is not always easy to identify how these databases differ in terms of their data collection, treatment and representation, nor which database is the most appropriate for a specific type of analysis. This practical guide aims to help trade negotiators, policy makers, researchers, and private sector actors to identify which international or national database to use for their analysis of preferential tariffs on agricultural products.
Despite an improvement in overall macroeconomic performance in Costa Rica, income inequality has risen and is currently at its maximum historical value. This is in stark contrast with other Latin American countries, which have recently made significant progress in reducing inequality. This study analyses the drivers of inequality in Costa Rica by decomposing the Gini coefficient by income source, finding that the main contributor to inequality in Costa Rica is labour income. In the period 2010-2014, public sector wages made the largest contribution to inequality, in particular wages of qualified workers. Within the public sector, wages of those working in public agencies outside central government contributed the most. Inequality has also been driven by a large and increasing skills premium in the private sector. Workers holding a tertiary degree earn, on average, nearly four times as much as those with only primary education. Social programmes, such as non-contributory pensions, do contribute to reduce inequality but their impact is limited given its small share in households’ total income. The analysis also quantifies the marginal effect on inequality of the different income sources, finding that an increase in wages of low qualified workers in the private sector would have the largest marginal impact to reduce inequality. Conversely, increases in wages of qualified workers in public and private sector would result in the highest increases in inequality.
Over the past two decades, aggregate labour productivity growth in most OECD countries has decoupled from real median compensation growth, implying that raising productivity is no longer sufficient to raise real wages for the typical worker. This paper provides a quantitative description of decoupling in OECD countries over the past two decades, with the results suggesting that it is explained by declines in both labour shares and the ratio of median to average wages (a partial measure of wage inequality). Labour shares have declined in about two thirds of the OECD countries covered by the analysis. However, the contribution of labour shares to decoupling is smaller if sectors are excluded for which labour shares are driven by changes in commodity and asset prices or for which labour shares are driven by imputation choices (primary, housing and non-market sectors). The ratio of median to average wages has declined in all but two of the OECD countries covered by the analysis and appears to reflect disproportionate wage growth at the very top of the wage distribution rather than stagnating median wages. The causes for these developments will be analysed in follow-up research.
The purpose of this paper is to explore the notion of decoupling with a view to improving understanding among economists, policy makers and agricultural trade negotiators, all of whom use the term in their deliberations but often with quite different meanings. The approach taken is conceptual or theoretical - designed to improve understanding of the different ways in which agricultural policies affect production and trade.
This paper is intended to clarify and facilitate discussion on areas that are an important part of the decoupling debate. This has been done using standard economic techniques and some illustrative examples.
quantifying some of the potentially important static, risk and dynamic effects and their implication on the degree of decoupling of different measures. Annexes 1 and 2 give some details of the issues investigated in each of the background studies.
Deepening regional integration within the Southern African Development Community (SADC) will raise potential growth for all member countries. Integrated economies will increase market size, trade opportunities and improve resource allocation across member countries. Key pillars of functioning regional integration are the free circulation of goods and services, mobility of workers and interconnected infrastructure. To boost regional integration, remaining tariff barriers and non-tariffs barriers should be removed. Ensuring greater compliance to agreements by SADC members will also facilitate intra-regional trade and cross-investments. More co-operation between competition authorities should facilitate harmonisation of competition rules in particular in services and transport-related services which would ease circulation of good and services. The other key pillars of regional integration (industrial policy, infrastructure, investment, financial integration and tax) are also reviewed.
As all safety systems in the majority of existing nuclear power plants use the preferred power supply, any voltage surges in these systems could lead to common-cause failures. In the event of an unusual electrical system transient, it is essential that safety-related equipment be isolated or protected from the fault in order to ensure its ability to safely shut down the reactor and remove decay heat.
Based on the analysis of the voltage surges observed at Forsmark-1 in 2006 and Olkiluoto-1 in 2008, this technical opinion paper summarises the current state of knowledge of in-plant and external grid-related challenges to nuclear power plant safety-related electrical equipment. It will be of particular interest to nuclear safety regulators, nuclear power plant operators and grid system regulators and operators.
As AI use grows, so do its benefits and risks. These risks can lead to actual harms ("AI incidents") or potential dangers ("AI hazards"). Clear definitions are essential for managing and preventing these risks. This report proposes definitions for AI incidents and related terms. These definitions aim to foster international interoperability while providing flexibility for jurisdictions to determine the scope of AI incidents and hazards they wish to address.
This paper was prepared as background for a discussion held at the OECD in November 2016 on the definition of geographical markets across national borders. It describes the process with an emphasis on markets that may extend beyond national borders. It also discusses how geographic market definition fits relative to competitive assessment, and the tendency of some authorities to leave definition open in cases where no competition concerns are present.
The paper examines how “green” investments are defined across different asset classes (equities, bonds and alternative investments), as well as providing some estimates of the size of these markets. The paper concludes that, given the lack of consensus on the usage and definition of the term “green”, the most productive approach could be to take an open and dynamic stance towards definitions and standards, with international institutions and governments adopting a “governance approach to green investment”.
