The OECD’s New Approaches to Economic Challenges initiative invited experts from inside and outside the Organisation to discuss complexity theory as a means to better understand the interconnected nature of the trends and influences shaping our socio-economic environment. Their contributions, brought together here, examine the assumptions, strengths and shortcomings of traditional models, and propose a way to build new ones that would take into account factors such as psychology, history and culture neglected by these models. The authors concentrate on the discipline of economics as such; the financial system; and applications of complexity theory to policy making and governance. They argue that a new narrative is needed to integrate the hopes, values, attitudes and behaviours of people into economics along with the facts and data economists are more used to dealing with.

Intense exploitation of our oceans and seas is degrading marine biodiversity and ecosystems at an alarming rate. This report presents good practice insights for effectively managing marine protected areas (MPAs), one of the policy instruments available for the conservation and sustainable use of marine biodiversity and ecosystems. While global coverage of MPAs has been increasing over the past two decades, further efforts are required to meet the target under the Sustainable Development Goals and to ensure they are effective.Drawing on the literature and numerous examples from developed and developing countries, this book highlights how the environmental and cost effectiveness of MPAs can be enhanced. It covers issues including the benefits and costs of MPAs, the need for more strategic siting of MPAs, monitoring and compliance, sustainable finance for MPAs, and the need to embed these in a wider policy mix so as to address the multiple pressures on marine ecosystems.

The OECD Sovereign Borrowing Outlook provides regular updates on trends and developments associated with sovereign borrowing requirements, funding strategies, market infrastructure and debt levels from the perspective of public debt managers. The Outlook makes a policy distinction between funding strategy and borrowing requirements. The central government marketable gross borrowing needs, or requirements, are calculated on the basis of budget deficits and redemptions. The funding strategy entails decisions on how borrowing needs are going to be financed using different instruments and which distribution channels are being used. This edition provides data, information and background on sovereign borrowing needs and discusses funding strategies and debt management policies for the OECD area and country groupings. In particular, it examines: gross borrowing requirements; net borrowing requirements; central government marketable debt; interactions between fiscal policy, public debt management and monetary policy; funding strategies, procedures and instruments; liquidity in secondary markets; implications of a low interest environment for government debt; and the outlook of inflation linked bonds.

Growth in Colombia has been among the strongest in the region, reflecting the flexible exchange rate and inflation targeting monetary policy, and fiscal rules. The strong growth and welfare programmes to the most vulnerable groups have substantially reduced poverty. Lower taxes and fees on wages have brought more people to better quality formal jobs, thereby raising both productivity and inclusiveness. Productivity and job opportunities have also been enhanced by recent reforms facilitating the opening of business, obtaining construction permits, registering property and paying taxes. However, productivity growth is still low and the gap between rich and poor among the highest in Latin America. Informality and gender gaps remain high, and social mobility low. Years of armed conflict, stringent local regulations and distortions in the tax system have created disparities in productivity and access to basic services across regions. Further simplifying procedures for company registration and the affiliation of workers to social security, improving labour market programmes, expanding early childhood education, and raising education quality would boost inclusion, social mobility and living standards. Greater and more affordable child, elderly and disability care would open the job market to more women. Raising productivity will be fundamental to continued increases in living standards for all Colombians.SPECIAL FEATURES: PRODUCTIVITY; INCLUSIVE GROWTH
