Landscape is defined by the European Landscape Convention as “an area perceived by people, whose character is the result of the action and interaction of natural and/or human factors”. Many efforts have been devoted in addressing the core concepts on which this definition roots: perception and interaction of men and nature, but when coming to large (continental) scale assessments, the latter prevail on the former.This paper aims at presenting a framework for a measurable landscape awareness indicator as a key link to the public demand for a specific type of landscape: the agricultural landscape. This is a necessary effort to complement more physically based assessments, which include as well the impact of human activities on landscapes.The analysis is carried out at different levels of governance: EU and regional, using an example from the Alentejo region in Portugal and EU wide databases, and addresses conceptual and practical questions: what type of societal landscape awareness can be monitored and by whom (e.g., individuals, specific social groups, society as a whole); what are the landscape dimensions that should be assessed; what are the limitations imposed by data-related constraints. By applying the methodology to build composite indicators to map landscape societal awareness, the paper shows the regional and local meaning of indicator approaches developed at European level, presents developments for downscaling to regional level, while introducing the social component to support sound policy development for European rural landscapes. 相似文献

A goal of this paper is to make sense of the seemingly puzzling behavior of interest rates and inflation – and the role of central banks in that behavior – during and after the Great Recession, particularly in the United States. To this end, we construct a model in which government debt plays a key role in exchange, and can bear a liquidity premium. If asset market constraints bind, then there need not be deflation under an indefinite zero interest rate policy (ZIRP). Further, ZIRP may not be optimal under these circumstances. A Taylor-rule central banker could be subject to a ZIRP trap and persistently undershoot target inflation. As well, a liquidity premium on government debt creates additional Taylor rule perils, because of a persistently low real interest rate. We make a case that this is the key policy predicament currently faced by many central banks in the world. 相似文献

This paper aims to analyse the feasibility of policy coordination among the ASEAN-5 economies. This is done by determining whether they experience symmetric responses to common shocks. Given that the problem of dimensionality plagues large-scale macroeconomic modelling, a Global VAR model by Pesaran, Schuermann, and Weiner (2004) and Dees, Mauro, Pesaran, and Smith (2007) is used. The results in this paper provide some weak evidence of symmetric responses to the common (global) shocks of interest: a US monetary policy shock, a US output shock, a Chinese output shock; an oil price shock. Shocks from the US produced the most symmetric responses. The lack of symmetry in some cases has implications for further policy coordination. Since migrant remittances could provide an adjustment mechanism, further labour market integration is needed as it currently lags behind trade and financial integration in the region. 相似文献

We compare certification to a minimum quality standard (MQS) policy in a duopolistic industry where firms incur quality-dependent fixed costs and only a fraction of consumers observe the quality of the offered goods. Compared to the unregulated outcome, both profits and social welfare would increase if firms could commit to producing a higher quality. An MQS restricts the firms׳ quality choice and leads to less differentiated goods. This fuels competition and may therefore deter entry. A certification policy, which awards firms with a certificate if the quality of their products exceeds some threshold, does not restrict the firms׳ quality choice. In contrast to an MQS, certification may lead to more differentiated goods and higher profits. We find that firms are willing to comply with an ambitious certification standard if the share of informed consumers is small. In that case, certification is more effective from a welfare perspective than a minimum quality standard because it is less detrimental to entry. 相似文献

Weak institutional development and information flows have constrained the extent to which the smallholder farming sector in developing countries can significantly drive growth and poverty reduction. This is despite widely implemented economic liberalisation policies focussing on market efficiency. Farmer organisations are viewed as a potential means of addressing public and private institutional failure but this has frequently been limited by inequalities in access to power and information. This article investigates two issues that have received little research attention to date: what role downward accountability plays in enabling farmer organisations to improve services and markets, and what influences the extent to which downward accountability is achieved. Kenya Tea Development Agency (KTDA), one of the largest farmer organisations in the world (>400,000 farmers) is examined alongside wider literature. Mixed methods were used including key informant interviews, and eight months of participant observation followed by a questionnaire survey. The article concludes that without effective downward accountability farmer organisations can become characterised by institutions and mechanisms that favour elites, restricted weak coordination and regulation, and manipulated information flows. This in turn reduces individuals’ incentives to invest. If farmer organisations are to realise their potential as a means of enabling the smallholder sector to significantly contribute to economic growth and poverty reduction, policy and research needs to address key factors which influence accountability including: how to ensure initial processes in formation of farmer organisations establish appropriate structures and rules; strong state regulation to enhance corporate accountability; transparent information provision regarding actions of farmer organisation leaders; and the role independent non-government organisations can play. Consequently attention needs to focus on developing means of legitimising rights, building poor people's capacity to challenge exclusion, and moving from rights to obligations regarding information provision. 相似文献

The daily trip to work is ubiquitous, yet its characteristics differ widely from person to person and place to place. This is manifested in statistics on mode and distance of travel, which vary depending on a range of factors that operate at different scales. This heterogeneity is problematic for decision makers tasked with encouraging more sustainable commuter patterns. Numerical models, based on real commuting data, have great potential to aid the decision making process. However, we contend that new approaches are needed to advance knowledge about the social and geographical factors that relate to the diversity of commuter patterns, if policies targeted to specific individuals or places are to be effective. To this end, the paper presents a spatial microsimulation approach, which combines individual-level survey data with geographically aggregated census results to tackle the problem. This method overcomes the limitations imposed by the lack of available geocoded micro-data. Further, it allows a range of scales of analysis to be pursued in parallel and provides insights into both the types of area and individual that would benefit most from specific interventions. 相似文献

高技能人力资本对于我国经济转型的重要性不言而喻。本文以2009—2012年间39个城市集中出台的地方人才引进政策为准自然实验,采用多期政策的双重差分法,结合机制分析和异质性分析,探究了人才政策出台前后区域创新能力的变化及其背后的机制和深层次原因,并分析政策效应在不同的地区营商环境、科教事业投入力度、知识产权保护程度下的差异。本文主要结论包括,地方人才引进政策总体上提高了当地的专利授权总量和专利价值总量;显著增加了研发投入的规模,但创新效率没有得到明显提升;在营商环境较差的地区,政策的效应侧重于提高专利数量,营商环境较好的地区则侧重于提升专利价值;在科教投入力度本身就很大的地区,政策效果较小,在科教投入弱的地区效果会更明显;在知识产权保护程度弱的地区,政策效果更多地表现为提高专利数量,保护程度强的地区,则侧重于提升专利价值。上述结论对地方政府优化人才激励政策、实施创新驱动发展战略具有一定的政策启示。 相似文献

本文利用SVAR模型脉冲偏导分离技术,从利率市场化和影子银行两个维度测算了金融市场化进程对货币政策不同传导渠道相对地位的影响。实证结果揭示了中国货币政策传导的一些重要特征:第一,以信贷渠道为代表的数量化渠道效应要强于以利率和汇率渠道为代表的价格渠道,并且该结果没有因金融市场化的推进而改变。第二,利率市场化的推进主要强化了利率渠道的作用,但一定程度上弱化了其他渠道尤其是信贷渠道的作用。第三,影子银行的发展,强化了资产价格渠道的效应,而相对弱化了信贷渠道和利率渠道的效应。研究为在金融与实体经济市场仍存在一定程度摩擦的条件下,央行采用价格与数量货币政策调控方式有机结合的必要性与有效性,提供了实证支持。同时研究还表明,要充分发挥利率市场化改革完善货币政策价格传导机制的作用,既需要加强对各种形式金融创新的监管,还需要实体经济体系进一步市场化改革相配合。 相似文献

创业企业迁徙是创业企业成长过程中的重要决策。基于文献研究并结合创业企业家特征,构建创业企业迁徙意愿影响因素模型,重点探讨在不确定性容忍度影响下创业企业迁徙意愿影响因素及其作用机制。研究结果表明,政策环境、生活质量、政府服务质量是影响创业企业迁徙的三大外部因素,创业企业家不确定性容忍度则是重要的内部因素,随着创业企业家不确定性容忍度提高,生活质量对迁徙意愿的影响减弱,而政策环境对迁徙意愿的影响增强,表明当前创业企业孵化与迁徙受政策环境主导。研究结论进一步解释了迁徙情景中创业企业对区域经济环境不敏感以及云集于北上广深等生活成本畸高的城市等现象。 相似文献
