Widespread supply disruptions in the wake of the COVID-19 pandemic and the Russian Federation’s large-scale aggression against Ukraine have raised concerns among policy makers that globalised value chains expose domestic production to shocks from abroad. This paper uses new indicators of global value chain dependencies and exogenous pandemic shocks to econometrically estimate the effects of supply disruptions abroad on domestic output. The results suggest that the adverse effects of supply disruptions are particularly large when concentration of supplying countries and supplying firms is high. Counterfactual simulations of the econometric model suggest that diversification of suppliers would have sizeable benefits in terms of shielding domestic production against country-specific supply shocks, with partial onshoring of production having only small additional benefits. Technological innovation that reduces foreign dependencies, such as the substitution of renewable energies for fossil fuels, can have similar benefits as diversification.
While teachers’ initial education is key to ensuring that new teachers are prepared for their work, it is only one piece in the continuum of teachers’ professional growth. Continuing professional learning is vital for teachers to broaden and deepen their knowledge, keep up with new research, tools and practices and respond to their students’ changing needs. It also plays a key role in building collaborative school cultures and supporting the collective improvement of the teaching profession. While the importance of continuing teacher learning is widely recognised, building efficient, equitable and sustainable professional learning systems is far from trivial. The OECD Teachers’ Professional Learning (TPL) study seeks to support the development of effective TPL policies and practices in schools and school systems. This paper proposes a theoretical and analytical framework for the study, systematically maps available OECD indicators to this framework and identifies information gaps and areas for future comparative work.
Four decades of rapid economic expansion in China has generated enormous pressure on the environment, natural resources and public health. Alarming smog outbreaks during the 2010-13 period prompted the government to introduce a number of reforms to control air pollution, including a re-organisation of environmental institutions, improving the coordination and integrity of enforcement actions across levels of government, and the rolling out of a permit system for all stationary pollution sources. This paper reviews these recent developments, and discusses key remaining challenges. The paper complements two case studies on air quality policies in Korea and Japan, and a third case study on international regulatory cooperation on air quality in North America, Europe and North-East Asia.
The pollution intensity of the Japanese economy, measured as emissions per dollar of GDP, is among the lowest within OECD countries. However, air pollution remains a significant issue. Almost 80% of the Japanese residents were exposed to an annual concentration of PM2.5 above the WHO guideline while the attainment rate of the domestic air quality standard for photochemical oxidants is below 1%. The analysis of the regulatory and enforcement framework for air quality management in Japan identifies best practises and key remaining challenges, including a limited understanding of the generation mechanism of ozone pollution and the need to strengthen cooperation among Prefectures. This paper complements two case studies on air quality policies in China and Korea, and a third case study on international regulatory cooperation on air quality in North America, Europe and North-East Asia.
During past years, Korea figured among the OECD countries with the highest share of population exposed to excessive PM2.5 (atmospheric particulate matter that have a diameter of less than 2.5 micrometres) concentrations and PM2.5 concentration level in Seoul is about two times higher than the WHO’s guidelines or the levels of other major cities in developed countries. A number of countermeasures have been recently introduced to address such challenges, including a tightening of air quality standards and increasing local inspection and enforcement capacity. This paper reviews these recent reforms, and discusses possible further improvements. This paper complements two case studies on air quality policies in China and Japan, and a third case study on international regulatory co-operation on air quality in North America, Europe and North-East Asia.
This policy brief examines the phenomenon of home-based entrepreneurship. It provides information on the types of businesses that entrepreneurs are most likely to operate out of the home, their reasons for this choice, and barriers to the development of home-based businesses. It examines how public policy approaches can better support home-based businesses, including removing hindrances in regulations and improving access to business development services. Key policy lessons are highlighted, including on how policy makers can increase social and labour market inclusion through taking better account of home-based businesses. This policy brief is part of a series of reports produced by the OECD on inclusive entrepreneurship. The series includes policy briefs on women’s entrepreneurship, youth entrepreneurship, senior entrepreneurship, access to business start-up finance for inclusive entrepreneurship and entrepreneurship by the disabled, as a well as reports on ‘The Missing Entrepreneurs’.
This policy brief on women in entrepreneurship was produced by the OECD and the European Commission. It explores the gender gap in entrepreneurship, the differences between male- and female-owned businesses, and the unique challenges that female entrepreneurs face when it comes to starting a business. Policy makers can support female entrepreneurs by promoting a positive attitude and female role models, offering training courses and mentoring, facilitating access to finance, and ensuring that their policies help women to participate in the labour market.
This policy brief is part of a series of documents produced by the OECD and the European Commission on inclusive entrepreneurship. The series includes policy briefs on youth entrepreneurship, senior entrepreneurship, social entrepreneurship, evaluation of inclusive entrepreneurship programmes, access to business start-up finance for inclusive entrepreneurship and entrepreneurship by the disabled as a well as a report on ‘The Missing Entrepreneurs’. All these documents are available in English, French and German. They are available at http://www.oecd.org/cfe/leed/inclusive-entrepreneurship.htm.
