This policy brief examines the impact of the COVID-19 crisis on vocational education and training (VET) systems and how VET systems are responding in OECD countries. The brief also presents steps that governments can take in the context of this crisis to build foundations for tomorrow’s strong and resilient VET systems.
In the recent past, the analysis of plant transients and the analysis of reactor core behaviour were performed separately. Usually, the core was represented by a point kinetics model to analyse plant transients and, for the core physics calculations, boundary conditions were imposed at the inlet and the outlet of the core. In reality, these boundary conditions depend on the power generation in the core. To ensure a realistic description of the physical phenomena in an accident analysis, the application of coupled codes is required. In recent years code developers began coupling three-dimensional (3-D) neutron kinetics codes with advanced thermal-hydraulics system codes. Such complex computer codes allow modelling of the entire reactor system, including a 3-D neutronics core. When reactivity initiated accidents with an asymmetric neutron flux distribution in the core are analysed, only such coupled codes are capable of estimating the real feedback effects. These codes can perform safety analyses in order to replace the conservative estimations with best-estimate calculations.
This report presents the VVER MOX Core Computational Benchmark Specification and Results, which was proposed as a benchmark within the OECD/NEA Expert Group on Reactor-based Plutonium Disposition (TFRPD). Benchmark results, obtained using three computer codes, are presented. The codes include: the MCU Monte Carlo code (Kurchatov Institute, Russian Federation), RADAR (Kurchatov Institute, Russian Federation), and the MCNP Monte Carlo code (GRS, Germany). The codes use different methods and different nuclear data. A comparison of the results shows good agreement among the various codes.
Global value chains (GVCs) in agriculture and food sectors have the potential to influence trading relationships and the gains from trade for different sectors along the value chain. This report explores the way in which value from trade and GVC participation is created for the agriculture sector. It examines differences in returns to the sector from participation in GVCs and trade either directly in contrast to participation that relies on downstream domestic processing. The study makes use of a database on trade in value added for 22 agro-food sectors derived from the Global Trade Analysis Project (GTAP) database. The evidence presented in this paper suggests that aggregate value to the agriculture and to the economy overall from direct participation in trade and GVCs generates at least as much value as participation that relies on domestic downstream processing. Similar overall gains from primary exports are associated with greater volumes and the value created from ‘value addition’ to these exports – the embodied service and other inputs. Indeed, countries that specialise in primary exports have higher shares of service value added in these exports, with this also being a determinant of value growth for middle-income countries.
Marine data play a crucial role for many scientific disciplines, as well as for very diverse operational services such as fisheries management, environmental planning, marine conservation, weather forecasting, or port management. The information derived from marine data is also increasingly finding its way into a wide and varied range of public policy arenas and private industries. Collecting, distributing and archiving public marine data provide benefits to society at large, however as with all public investments, assessments are needed to provide evidence to decision makers. Based on an original survey of UK marine data users, this paper explores pathways through which marine data are used and transformed into actionable information, creating systematised value chains for the first time. The analysis unveils trends in current marine data uses in the UK and key benefits of data uses. The paper lays the foundations for further OECD work with the marine data community.
The Menzis Shared Savings Program was initiated in 2014 by the Dutch insurer Menzis and the national primary care organisation Arts en Zorg, and is among the first value-based payment models for primary care in Europe. It runs as a complement to the current – volume-driven – primary care payment system. This paper reviews the evidence of the impact of this programme against its stated objectives. The Menzis Shared Savings Program led to a lower volume of care, particularly in terms of referrals to specialist care, laboratory care and general practitioners care. Main facilitating factors were the advanced data infrastructure in place, communication and transparency about the programme’s parameters, and the programme’s focus on mitigating financial risk and uncertainty for providers. Shared savings models – even when added as a mere complement to existing volume-driven payment methods – could enhance value in health systems.
Values and ethics are automatically incorporated into any teaching/learning environment or endeavour, whether or not they are consciously stated objectives. The focus on “quality of education” has sharpened as people have become concerned about a perceived rise in materialism as standards of living have improved; materialistic ambitions increasingly fill the ideological gap created by the move to a pluralistic society in which there is a less general consensus of values and ethics. There is increasing demand for insight into the potential of the formal teaching/learning process for inculcating, learning/unlearning (as the case may be) and consolidating values. The manner in which teachers are trained has far-reaching implications for the youth in schools, and a systemic inquiry into the structure, role, responsibilities, aims and curricular objectives of teacher education is the obvious starting point. This paper tries to delineate the global normative aims of education as a model for assessing the composition of the teacher education curriculum in Pakistan. It looks at the intended curriculum, bearing in mind that the formal and the active curricula may not necessarily converge. The paper accepts that ethics and values education is still in a formative stage. However, one critical question that will remain open at the philosophical level is “which values should be included?” and this needs to be vigorously researched to establish guidelines that have global consensus. The next crucial question will then be “how best to teach to ensure that these ethics and values are internalised by learners?”
This paper is based mainly on responses – nearly 300 – to a web-based survey of academic staff in UK higher education. The survey examined their personal and professional values and their views on the values that should underpin higher education. Their perceptions of current reality in terms of national policy and processes and of institutional management expectations, with examples provided of events that disturbed them, raise questions about the longer term health of higher education as it has been understood. The project was seen as a pilot aiming to provoke debate about how well traditional values and standards “fit” with mass levels of higher education provision, and government emphases on the economic role of higher education. The findings are set in a theoretical context drawing on models by Clark (1983), Becher and Kogan (1992) and the author (McNay, 1995, 2005a).
Asthma is a non-communicable and non-curable lung disease that is associated with an array of environmental contaminants and chemicals. Many of these hazards are subject to regulation, or may be considered for regulation, in order to reduce exposures and prevent human health risks. However, the available information on willingness-to-pay (WTP) to avoid asthma or reduce its severity is scarce, incomplete and does not provide estimates compatible with welfare economic theory that can be used in cost-benefit analysis.
This paper is part of the series of large scale willingness to pay (WTP) studies resulting from the Surveys to elicit Willingness to pay to Avoid Chemicals related negative Health Effects (SWACHE) project that intends to improve the basis for doing cost-benefit analyses of chemicals management options and environmental policies in general. The present paper offers values suitable for use in cost-benefit analyses of the WTP for reduced severity of asthma attacks in adults and children and in reduced probability of getting asthma for these two population groups, all in the context of reducing chemical exposures, and covering populations in seven OECD countries: Canada, Czech Republic, France, Poland, Sweden, the United Kingdom and the United States. The context for such WTP elicitations was a set of household products that contain fewer hazardous chemicals than what is currently available in supermarkets but are more expensive.
Compromised kidney function is associated with an array of environmental contaminants and chemicals, including heavy metals, certain organic solvents, and polycyclic aromatic hydrocarbons (PAHs), as well as food and waterborne pathogens. Many of these hazards are subject to regulation, or may be considered for regulation, in order to reduce exposures and prevent human health risks. However, valuation estimates for kidney effects that can be used in cost-benefit analyses are few, particularly willingness-to-pay estimates. In particular, there appears to be no willingness-to-pay (WTP) estimate available for reduced risk of chronic kidney disease and therefore no estimate for the Value of a Statistical Case (VSC) of chronic kidney disease.
This paper is part of the series of large scale willingness to pay (WTP) studies resulting from the Surveys to elicit Willingness to pay to Avoid Chemicals related negative Health Effects (SWACHE) project that intends to improve the basis for doing cost benefit analyses of chemicals management options and environmental policies in general. The paper details a stated preference survey estimating WTP to reduce the risk of symptomatic chronic kidney disease, termed serious kidney disease in the survey instrument, filling an important gap in the valuation literature and addressing a need for applied benefits analysis for chemicals regulation. The SWACHE serious kidney impairment survey was fielded in 10 countries: Canada, Chile, China, Denmark, Germany, Italy, Norway, Türkiye, the United Kingdom and the United States.
While fertility decline is a global phenomenon that has many causes, part of it can be explained by exposure to substances linked to reproductive toxicity that are produced and lead to human exposure through the environment and products. Authorities face challenges in regulating reprotoxic substances through actions such as bans and prohibitions, because of the difficulty in explicitly considering the economic benefits and costs of such regulations. Moreover, economic studies that show the value of reducing infertility caused by chemical exposure are not yet available.

There is ample evidence that exposure to various chemicals can increase the probability of children to be born with low or very low birth weight. Infants born with very low birth weight have a higher risk of suffering from neurosensory problems, issues related to behavioural and social competencies, and learning disabilities than infants born with normal birth weight. Authorities face challenges in regulating chemical substances through actions such as bans and prohibitions, because of the difficulty in explicitly considering the economic benefits and costs of such regulations. Moreover, existing Values of a Statistical Case (VSC) of very low birth weight are rare and cannot be directly applied to the cost benefit analysis of chemical management options for a wide range of countries.

This working paper proposes a methodology to monetise five aspects of employee well-being (wage inequality, being employed, excess working hours, relationships with management and job security) using theoretical and empirical frameworks drawn from welfare economics. Preliminary results highlight a large loss of welfare arising from within-firm wage inequality as well as a strong impact of working conditions on workers’ well-being. On the aggregate, suppressing the negative externalities of the firm linked to excess working hours, tensions with management and job insecurity would yield an increase in social welfare equivalent to a 25% increase in household income, representing many years of economic growth. Greater transparency on company wage distributions and working conditions is necessary to apply these methodologies to real firms.
This paper uses options pricing techniques to estimate the value of the government’s tax claim on household or business incomes. It treats the annual tax claim as a European call option on taxable income (a European call is an option that can be exercised at its expiration date and not before). The option’s expiration date is the end of the fiscal year and its strike price is the threshold level of income below which income is not subject to tax. The paper derives three alternative valuation formulas, each associated with an alternative functional form for the tax code (a flat tax, a step-function and a more general tax function). The application of options pricing theory to tax claims is found to be relatively straightforward. The approach proposed here could be used to refine accounting on the assets side of the government’s balance sheet. It would not be more difficult to implement than many common applications of options theory ...
Exposure to chemicals has been shown to reduce IQ in children. In turn, a person’s IQ is likely to affect their educational achievements, which may then affect lifetime earnings, more generally, a person’s quality of life. At the same time, authorities face challenges in regulating chemical substances through actions such as bans and prohibitions, because of the difficulty in explicitly considering the economic benefits and costs of such regulations. Moreover, economic studies that show the value of reducing IQ loss caused by chemical exposure are not yet available.
