This study provides a survey of recent advances in the literature on proposed African monetary unions. The survey comprises about 70 empirical papers published during the past 15 years. Four main strands are discussed individually and collectively. They comprise the proposed: (i) West African Monetary Zone (WAMZ), (ii) East African Monetary Union (EAMU), (iii) Southern African Monetary Union (SAMU) and (iv) African Monetary Union (AMU). We observe a number of issues with establishing the feasibility and/or desirability of potential monetary unions, inter alia, they are variations in: choice of variables, empirical strategies, sampled countries and considered periodicities. We address this ambiguity by reviewing studies with scenarios that are consistent with Hegelian dialectics and establish selective expansion as the predominant mode of monetary integration. Some proponents make cases for strong pegs and institutions as viable alternatives to currency unions. Using cluster analysis, disaggregating panels into sub-samples and distinguishing shocks from responses in the examination of business cycle synchronisation provide more subtle policy implications. We caution that for inquiries using the same theoretical underpinnings, variables and methods just by modifying the scope/context and periodicity may only contribute to increasing the number of conflicting findings. Authors should place more emphasis on new perspectives and approaches based on caveats of, and lessons from the European Monetary Union (EMU) and CFA zones.  相似文献

The conservation and management of protected areas in urban settings has become increasingly challenging with dynamics over land use change in adjacent urban areas being highly relevant to, but at times conflicting with, the protected area. This study seeks to better understand the implications of land use change processes to urban protected area management through the case study of the Las Piñas – Parañaque Critical Habitat and Ecotourism Area (LPPCHEA) in Metro Manila, Philippines. Factors and processes influencing land use change and protected area management and the impact of stakeholders’ perceptions on protected area were analyzed. The urban protected area in itself has limited influence on its surrounding urban areas, as land use change in these areas is shaped more by social, economic and policy/institutional factors occurring within the context of urban-regional development. The study also found that land use conflict is evident in an urban protected area due to the competing ecosystem services derived by various stakeholders. This discord is deepened by the lack of coordination between land use planning and protected area management. Integrating protected area management with land use planning through legally binding instruments, specific timeframes and clear internal procedures can help resolve land use conflict for an urban protected area at the strategic or policy level.  相似文献

21世纪以来,亚太地区区域贸易协定(RTA)签署的数量激增,学术界理论与现实出现悖论,引发学者思考各国热衷于建立RTAs背后的原因并探索新的研究方法。本文首次从RTAs数量和质量的影响效应哪个更为重要的视角,将发达国家和发展中国家进行对比分析,深入探究发达国家在新时期推进新一代贸易协定规则的原因。通过比对RTA协议的每一条条款,测算出涉及传统WTO+和新一代WTO-X领域的条款覆盖率和法定承诺率指标来衡量RTA的质量,实证分析得出,签署高质量的区域贸易协定能更有效地推动亚太地区的经济增长和人民福利水平的提高,该影响效应在发达国家中更为明显,而发展中国家受限于执行能力在新一代规则下签订RTA对经济增长的作用不显著。  相似文献

This is a review article that unifies several important examples using constrained optimisation techniques. The basic tools are three simple mathematical optimisation results subject to certain constraints. Applications include calibration, benchmarking in small area estimation and imputation. A final illustration is constrained optimisation under a general divergence loss.  相似文献

Social and economic developments in rural regions call for a discussion of strategies of dealing with redundant traditional buildings. Using a social science approach, our study examines how the local population in two rural regions perceives the built heritage and which factors are underlying these perceptions. People’s attitudes towards maintaining the cultural heritage vary considerably and are partly influenced by the socio-cultural and economic context of the region. The present article discusses some of the core regional socio-cultural influences on attitudes towards the rural built heritage. Following from qualitative interviews, the article concludes that the scale of perception of the built heritage is related to the “liveliness” of the local culture: The more original and distinctive the local culture is, and the more the local economy is still based on agriculture, the wider the scale of perception of the traditional cultural landscape and built heritage. In a region with local traditions that are alive and followed in everyday life, and a local economy that is mainly based on agriculture, the entire settlement structure is perceived as cultural heritage. In such areas, alternative uses should be found for redundant buildings. In contrast, in regions where the culture is less visible and alive nowadays and where the local economy has changed, people tend to perceive single buildings as representing their cultural heritage, and they often wish to preserve and conserve such remaining houses, barns and stables. In the study, we show that from a social science point of view, there is no universal perception of the maintenance of built cultural heritage. Rather, we see different views and opinions that are important to consider when it comes to developing heritage protection strategies together with public authorities.  相似文献
