To help policymakers form a judgment on inflation risks and the required monetary policy stance the OECD has developed an analytical framework based on a set of 'eclectic' Phillips curves estimated for the two largest OECD economies, the United States and the euro area, which is presented in this paper. This framework is used in the preparation of the Economic Outlook to explain recent developments in core inflation, excluding food and energy, based on developments in measures of economic slack (the output gap), spill-over effects from energy prices onto core inflation and lagged responses to past inflation via expectations formation. The fact that the knock-on effects from energy shocks onto core inflation appear small in comparison with the 1970s can be explained by the secular fall in energy intensity, a low and stable rate of 'mean inflation' -- to which observed inflation reverts after a shock has worked its way through -- and persistent slack in the aftermath of the bursting of the dotcom bubble.

Energy Management, in the context of small island economies depending heavily on imported fossil fuels, is here analyzed. Mauritius, vulnerable also in terms of high population density and fragile ecosystems, is the focus of a national project called Maurice Ile Durable (MID or Mauritius Sustainable Island). The economic development over the past decade has been significant in the country and the national income tends to continue increasing. However, the supply, distribution and utilization of energy are critical issues for the future of the country. In this context, the challenges of Energy Management are found to be particularly of a politico-economic nature. Solutions are proposed towards overcoming the obstacles identified in order to achieve defined objectives.

In recent years, the continuous spread of the COVID-19 epidemic has impacted the supply chain of enterprises. Mitigating the supply chain’s vulnerability has great significance for the survival and development of enterprises. Optimizing the business environment and building a digital government will help improve the external environment for enterprise development. However, its impact on the vulnerability of the enterprise supply chain has yet to be studied. Taking the impact of COVID-19 as an example, this paper uses the survey data of nearly 40,000 enterprises of the National Federation of Industry and Commerce in 2020 and “10,000 private enterprises evaluating the business environment”, to conduct systematic empirical research and fill the research gap in this area. The study indicates that the business environment and digital government can significantly mitigate the impact of COVID-19 on the supply chain. This conclusion is still valid after a series of robustness tests. Mechanism analysis demonstrates that the business environment and digital government can prompt the government to introduce effective mitigation measures promptly, better guarantee production factors and logistics, and thus improve the vulnerability of the enterprise supply chain. This study deepens our understanding of the economic outcome of the business environment and digital government and also sheds new light on supply chain management.

Sustainably feeding the world’s growing population represents one of our most significant challenges. Aquaculture is well positioned to make contributions towards this challenge. Yet, the translation of aquaculture production innovations into benefits for rural communities is constrained by a limited understanding of the social dynamics that influence the adoption of new agricultural practices. In this paper, we investigate the factors that shape the spread of small-scale tilapia aquaculture through rural Solomon Islands. Based on diffusion of innovation theory, we focus on three potentially influential factors: (i) socio-economic characteristics of adopters; (ii) the role of opinion leaders; and (iii) characteristics of the innovation. We find that farmers who were wealthier, older, and had more diverse livelihoods were most likely to be adopters. Opinion leaders facilitated the adoption of tilapia aquaculture, but lacked the capacity to provide fundamental knowledge necessary to realize its potential benefits to food security. The paper argues for more explicit attention to the poorest households and makes the case for a deeper engagement with the broader social and institutional contexts that shape the adoption process. Aquaculture interventions that account for these social dynamics are critical for translating production innovations into sustainable benefits to rural communities.

L'aquaculture joue un rôle important dans la sécurité alimentaire et fournit des moyens de subsistance et des emplois à des millions de personnes dans les communautés côtières du monde entier. Cependant, le secteur aquacole en pleine croissance a également suscité des débats sur sa durabilité écologique à long terme, sa viabilité économique, les inégalités sociales potentielles et les problèmes de gouvernance. Nous avons étudié les défis et les opportunités perçus pour parvenir à une aquaculture durable du crabe de boue dans les régions côtières tropicales en utilisant l'étude de cas des fermes côtières de crabe de boue dans l'Andhra Pradesh, en Inde. Sur la base des perceptions et des données financières indicatives d'un échantillon de parties prenantes, nous avons étudié les résultats économiques potentiels dans différents scénarios représentant des niveaux de rendement, des facteurs de risque et des périodes de projet variables. Les principaux risques identifiés par les parties prenantes étaient associés à l'approvisionnement limité en graines de crabe de boue et au manque d'accès aux programmes de soutien gouvernementaux et non gouvernementaux. Il n'y a pas de tampons financiers, donc des épidémies majeures ou des conditions météorologiques extrêmes causées par le changement climatique entraîneraient une perte de moyens de subsistance. Cet article met également en évidence le facteur le plus critique déterminant le niveau de succès de l'élevage du crabe de boue étant le taux de survie du crabe qui est influencé par une variété de facteurs, y compris l'augmentation de la température de la surface de la mer. Les résultats de cette étude montrent que l'élevage de crabes de boue à petite échelle comporte moins de risques et une plus grande flexibilité que l'élevage de crabes de boue à grande échelle. Il pourrait s'agir d'une entreprise économiquement durable et servir d'outil de réduction de la pauvreté dans les pays en développement si un soutien et une formation en matière de microfinance sont disponibles. La acuicultura desempeña un papel importante en la seguridad alimentaria y proporciona medios de subsistencia y empleo a millones de personas en las comunidades costeras de todo el mundo. Sin embargo, el creciente sector de la acuicultura también ha creado debates en torno a su sostenibilidad ecológica a largo plazo, viabilidad económica, posibles desigualdades sociales y problemas de gobernanza. Investigamos los desafíos y oportunidades percibidos para lograr una acuicultura sostenible de cangrejo de fango en las regiones costeras tropicales utilizando el estudio de caso de las granjas costeras de cangrejo de fango en Andhra Pradesh, India. Con base en las percepciones y los datos financieros indicativos de una muestra de partes interesadas, investigamos los posibles resultados económicos en diferentes escenarios que representan diferentes niveles de rendimiento, factores de riesgo y períodos de tiempo del proyecto. Los principales riesgos identificados por las partes interesadas se asociaron con el suministro limitado de semillas de cangrejo de fango y la falta de acceso a esquemas de apoyo gubernamentales y no gubernamentales. No hay amortiguadores financieros, por lo tanto, los grandes brotes de enfermedades o las condiciones climáticas extremas causadas por el cambio climático conducirían a la pérdida de los medios de vida. Este documento también destaca que el factor más crítico que determina el nivel de éxito del cultivo de cangrejo de fango es la tasa de supervivencia del cangrejo, que está influenciada por una variedad de factores, incluido el aumento de la temperatura de la superficie del mar. Los resultados de este estudio muestran que el cultivo de cangrejo de fango a pequeña escala tiene menos riesgos y una mayor flexibilidad que el cultivo de cangrejo de fango a gran escala. Podría ser una empresa económicamente sostenible y servir como una herramienta para el alivio de la pobreza en los países en desarrollo si se dispone de apoyo y capacitación en microfinanzas. Aquaculture plays a significant role in food security and provides livelihoods and employment for millions of people among coastal communities worldwide. However, the growing aquaculture sector has also created debates around its long-term ecological sustainability, economic viability, potential social inequalities and governance issues. We investigated the perceived challenges and opportunities to achieving sustainable mud crab aquaculture in tropical coastal regions by using the case study of coastal mud crab farms in Andhra Pradesh, India. Informed by perceptions and indicative financial data from a sample of stakeholders we investigated the potential economic outcomes under different scenarios representing varying yield levels, risk factors and project time periods. The main risks identified by the stakeholders were associated with the limited supply of mud crab seeds and the lack of access to governmental and non-governmental support schemes. There are no financial buffers, therefore major disease outbreaks or extreme weather conditions caused by climate change would lead to a loss of livelihoods. This paper also highlights the most critical factor determining the level of success of mud crab farming being the crab survival rate which is influenced by a variety of factors including increasing sea surface temperature. The results of this study show that small-scale mud crab farming has fewer risks and higher flexibility involved than large-scale mud crab farming. It could be an economically sustainable enterprise and serve as a tool for poverty alleviation in developing countries if microfinance support and training are available. تلعب تربية الأحياء المائية دورًا مهمًا في الأمن الغذائي وتوفر سبل العيش وفرص العمل لملايين الأشخاص بين المجتمعات الساحلية في جميع أنحاء العالم. ومع ذلك، فإن قطاع تربية الأحياء المائية المتنامي قد خلق أيضًا مناقشات حول استدامته البيئية طويلة الأجل، وقابليته الاقتصادية، وعدم المساواة الاجتماعية المحتملة، وقضايا الحوكمة. لقد حققنا في التحديات والفرص المتصورة لتحقيق تربية مستدامة لسرطان البحر الطيني في المناطق الساحلية الاستوائية باستخدام دراسة حالة لمزارع سرطان البحر الطيني الساحلية في ولاية أندرا براديش، الهند. استنادًا إلى التصورات والبيانات المالية الإرشادية من عينة من أصحاب المصلحة، قمنا بالتحقيق في النتائج الاقتصادية المحتملة في ظل سيناريوهات مختلفة تمثل مستويات عائد متفاوتة وعوامل خطر وفترات زمنية للمشروع. ارتبطت المخاطر الرئيسية التي حددها أصحاب المصلحة بمحدودية المعروض من بذور سرطان البحر الطيني وعدم الوصول إلى خطط الدعم الحكومية وغير الحكومية. لا توجد حواجز مالية، وبالتالي فإن تفشي الأمراض الرئيسية أو الظروف الجوية القاسية الناجمة عن تغير المناخ ستؤدي إلى فقدان سبل العيش. تسلط هذه الورقة الضوء أيضًا على العامل الأكثر أهمية الذي يحدد مستوى نجاح زراعة سرطان البحر الطيني وهو معدل بقاء سرطان البحر الذي يتأثر بمجموعة متنوعة من العوامل بما في ذلك زيادة درجة حرارة سطح البحر. تظهر نتائج هذه الدراسة أن زراعة سرطان البحر الطيني على نطاق صغير تنطوي على مخاطر أقل ومرونة أعلى من زراعة سرطان البحر الطيني على نطاق واسع. يمكن أن يكون مشروعًا مستدامًا اقتصاديًا وأن يكون بمثابة أداة للتخفيف من حدة الفقر في البلدان النامية إذا توفر الدعم والتدريب في مجال التمويل الأصغر.

Abstract Energy is indispensible in modern society and is one of the most important components of socio-economic development. Nepal is one of the least developed countries with more than 80% of its population residing in rural communities. Per capita energy usage – often viewed as a key index of the development – in the country is far less than the global average per capita energy usage. The energy sector is dominated by the traditional energy sources such as fuel woods, crop residues and animal dung mainly for domestic usage contributing to about 86% of the national energy consumption. Currently 40% of the population has access to electricity, and the rural electrification accounts for only 29%. The majority of rural populations are meeting their energy needs by burning biomass in traditional stoves which has several environmental and public health issues. Nearly all fossil-derived fuels consumed in the country are imported in a refined form, and the perpetual increase in petroleum imports has adversely impacted the existing fragile economy of the country. Despite a huge potential in harnessing various renewable energy resources such as hydropower, solar power, wind energy and biofuels/bioenergy, these resources have not been sustainably captured due to geographical, technical, political and economical reasons. This paper presents a brief account of Nepal's renewable energy resources and the current status of various renewable energy technologies (RETs) such as micro-hydro, solar power, wind energy, biofuel/bioenergy, improved cook stoves, and improved water mill. It also highlights the opportunities and barriers for the development of RETs. Finally this paper presents some recommendations for the promotion, development and implementation of RETs in the country.

Este trabajo presenta los resultados del estudio de caso del transporte informal de las comunas 15 y 18 de la ciudad de Cali. El transporte informal ha sido trabajado como una de las constantes en las ciudades latinoamericanas. En la literatura, este fenómeno se relaciona como un efecto de la implementacion de las políticas neoliberales de privatizacion de los sistemas de transporte o como una evidencia de la incapacidad de la Administracion pública y del Estado para hacerse cargo de su espacio de soberania. Este trabajo problematiza estos diagnósticos y sugiere una nueva manera de abordar el transporte informal en las urbes del sur global. Con técnicas etnográficas, el trabajo muestra como la informalidad es un espacio socialmente construido con tres caracteristicas principales: a) la persistencia de hombres prestadores del servicio y mujeres usuarias, ambos de bajos ingresos económicos, solidarios entre si para resistir ante un sistema oficial que los excluye; b) el uso significativo de esta clase de transportes de mujeres de estratos bajos que necesitan movilizarse, de manera flexible y económica, de zonas alejadas de los centros productivos, excluidos de los diseños de rutas de transporte, y c) la burocratización de las prácticas asociadas con la prestación del servicio informal. Estos hallazgos permiten sostener que los espacios urbanos son construcciones sociales que, al estar cruzadas por vectores de poder como el género, hacen que la experiencia geográfica de hombres y mujeres sea diferenciada.
