Social Democracy and Contextual Unemployment: New Zealand Labour in 1990

This paper examines the spatial implications of social-democratic policy transformation. It does so by exploring the political consequences of residential contextual unemployment engendered by a Labour government which had once been dedicated to maintaining full employment. Faced with economic crisis, as Przeworski's model predicts [Capitalism and social democracy, Cambridge University Press, Cambridge (1985)], New Zealand Labour, beginning in 1984, abandoned its traditional social-democratic statist policies, including the maintenance of full employment, and allowed unemployment to skyrocket under its stewardship. This meant subjecting its supporters to significant contextual cross-pressures, since many residential neighbourhoods became characterised by both high concentrations of Labour partisans, and by those recently unemployed by Labour's new market-liberal policies. Using original survey data merged with New Zealand census data, empirical findings show that residual partisan loyalties and a lack of a major party alternative constrained respondents' partisan disaffection, while channelling their disillusionment into both minor party voting and systemic, governmental criticisms - likely fuelling New Zealand's drive for electoral reform and a new system of proportional representation.     

番禺市农业结构的转变及其效果

单一化的经济不利于充分利用资源,而多元化的经济不利于高效利用资源。为了充分而高效利用资源,应该根据区域资源的实际状况确定合理的区域农业结构和专业化程度。１９８０年以来番禺市农业结构调整的效果表明,农业结构专业化程度降低的幅度越大,结构转变的效率越低,专业化程度降低的幅度越小,结构转变的效率就越高。区域农业发展的方向应该是在具有比较优势的行业专业化发展,在专业化基础上逐步实现规模化、基地化和农工贸一体化。     

1990—2018年中巴经济走廊冰湖时空变化特征

中巴经济走廊是贯通南北丝路的关键枢纽。在全球变暖的背景下, 区域内冰川变化情况复杂, 部分冰川出现前进或跃动现象, 冰湖溃决的风险在不断上升, 进而威胁中巴经济走廊的建设与民生安全。基于1990—2018年Landsat TM/ETM+/OLI遥感影像, 利用目视解译方法提取了中巴经济走廊3期冰湖编目数据, 并分析了28年来该区域内冰湖的总体变化趋势、 空间异质性以及成因。结果表明： 中巴经济走廊目前共发育有2 380个冰湖, 总面积为（131.76±19.08） km², 集中分布于喀喇昆仑山脉和喜马拉雅山脉; 1990—2018年期间, 冰湖总体面积扩张速度为0.48%·a^-1, 但各个山脉不同规模冰湖面积变化差异较大。中巴经济走廊在气温和降水的共同作用下, 区内冰湖面积呈扩张趋势, 同时气温和降水变化率的空间差异使得冰湖面积变化存在空间差异; 冰川的快速退缩增加了区内冰湖溃决的风险。     

Challenges for New Zealand's individual transferable quota system: Processor consolidation,fisher exclusion, & Māori quota rights

This paper identifies three management initiatives in New Zealand's Individual Transferable Quota system that facilitated consolidation of the processing sector and limited market access for fishers, even those with quota rights. They are: (1) the placement of responsibility onto a Māori trust in 1992 and tribes (iwi) in 2004 to manage a limited amount of quota to benefit all Māori, fishers and non-fishers, which increased the use of quota as an investment asset; (2) the creation of Annual Catch Entitlement (ACE) as a fish access right separate from the quota ownership right, which made it possible to overcome consolidation limits by leasing ACE; (3) the 1997 Licensed Fish Receiver Act that made it illegal for fishers to sell fish off the boat without food safety certification. This account of the fishery policy environment in New Zealand explains why, despite owning significant portions of New Zealand's fishing quota, few Māori are fishing, processing, or selling fish caught by Māori quota.     

Quantitative analysis for maritime delimitation: Reassessing the Bay of Bengal delimitation between Bangladesh and Myanmar

This article examines technical aspects of the maritime boundary dispute between Bangladesh and Myanmar (the ‘Bay of Bengal case’). This dispute was the first maritime delimitation determined by the International Tribunal for the Law of the Sea (ITLOS). The 2012 decision was also the first time that a maritime boundary for the seabed and subsoil of the Exclusive Economic Zone (EEZ) and the extended continental shelf (ECS) was determined by international adjudication. This was also therefore the first time that detailed technical quantification of seabed areas within the EEZ and ECS was needed for achieving an equitable division of these maritime zones in an international forum. Following review of the principles of maritime delimitation on which the ITLOS reached its determination, this article analyzes the legal status and delimitation effect of St. Martin's Island. Concerning the question of whether the legal regimes of the EEZ and continental shelf should be treated differently in a single delimitation line, although the ITLOS determined that the legal regimes should not be distinguished in the present case, a different approach is proposed for future cases. The article identifies how quantitative modelling can be used to achieve an equitable boundary and proposes a model to adjust provisional equidistance lines in accordance with the complex geophysical rules prescribed for the outer limits of the ECS in Article 76 of the United Nations Law of the Sea Convention (LOSC).     

How subsidies affect the economic viability of small-scale fisheries

This article presents the first bottom-up analysis of the proportion of global marine fisheries subsidies to small-scale fisheries (SSF). Using existing data, the reported national subsidy amounts are split into the fraction that goes to small- and large-scale fishing sectors. Results reveal a major imbalance in subsidy distribution, with SSF receiving only about 16% of the total global fisheries subsidy amount of $35 billion in 2009. To bring this into perspective, a person engaged in large-scale fishing received around 4 times the amount of subsidies received by their SSF counterparts. Furthermore, almost 90% of capacity-enhancing subsidies, which are known to exacerbate overfishing go to large-scale fisheries, thus increasing the unfair competitive advantage that large-scale fisheries already have. The developmental, economic and social consequences of this inequity are huge and impair the economic viability of the already vulnerable small-scale fishing sector. Conclusions indicate that taxpayers' money should be used to support sustainable fishing practices and in turn ocean conservation, and not to foster the degradation of marine ecosystems, often a result of capacity-enhancing subsidies. Reducing capacity-enhancing subsidies will have minimal negative effects on SSF communities since they receive very little of these subsidies to begin with. Instead, it will help correct the existing inequality, enhance SSF economic viability, and promote global fisheries sustainability.     

The discard ban policy,economic trends and opportunities for the Portuguese fisheries sector

In this paper the discard ban policy within the Portuguese fisheries sector is discussed and the opportunities and impact in the fisheries economy that arise from sales of unwanted fish under the new landing obligation are evaluated. The decadal mean price of fish (€/kg, adjusted for inflation) rose from the 1940s until the 1970s, dropping thereafter. The yearly averaged economic income estimated for discards sales between 1969 and 2009 ranged from 419345€ to 2164379€. Discard ban sales could contribute from 10% to 53% of the total landed value and 9–34% of the total catches (landings + discards). Under a discard ban policy, the fishing sector with the largest economic contribution for total discards sales would be multispecies (54%), followed by trawl (26%) and seine (20%). On average, fishing sales contributed with 0.63% to gross domestic production (GDP) between 1938 and 2009. Discard sales can increase 1.07–1.46 times more than the fish landing contribution to GDP. After 1983 the average landings/imports economic ratio was 0.28:1, which means that fish imports surpassed landings economic value 3.57 fold. The discard ban policy can create economic opportunities in the national context thus helping to revitalize some specific fisheries sectors.     

Communicating research on the economic valuation of coastal and marine ecosystem services

Quantifying the monetary value of ecosystem services (ES) provided by coastal and marine resources can help policy makers assess the trade-offs and synergies inherent in ecosystem-based management of marine and coastal environments, thus increasing the social efficiency of decision-making processes. As shown by the valuation literature, the number of coastal and marine management settings where valuation researchers have attempted to make a contribution is rising fast. However, this rise in research activity has not been matched by the increase in the use of economic valuation (EV) in the actual management of coastal and marine resources. This raises an interesting question: is EV responding to the needs of policy makers? This paper provides a comprehensive overview of the knowledge base regarding the economic values for coastal and marine ecosystems. It then discusses how to improve the uptake of ES valuation research by focussing on two core issues which are thought to be essential for more effective communication with the policy community.     

Social and economic consequences of 40 years of Dutch quota management

The Netherlands was one of the first nations to introduce ITQs in their fisheries to manage national yearly Total Allowable Catches (TACs). These ITQs have gradually developed from an individual quota system in 1976 to an ITQ system in the 1980s. In 1993 the system was reformed into a co-management system. In this paper it is argued that many of the usual negative socio-economic consequences of ITQs mentioned in the literature have been largely absent, due to the embeddedness of ITQs in co-management arrangements. However, cracks have appeared lately in this combined management system, allowing an identification of its vulnerabilities. These findings show that the social and economic structure of Dutch fisheries is changing from a rather cooperative to a more competitive and exclusive system, more like conventional ITQs.     

海洋产业结构变动对海洋经济效率影响研究

产业结构变动对经济增长影响已经得到了现代经济增长理论的肯定,但是产业结构变动对经济增长效率的影响一直是学术界没有解决的问题。目前中国已经进入了中等收入国家,粗放式增长逐渐结束,集约式增长越来越受到重视。文章基于海洋产业,研究了海洋产业结构变动对经济增长效率的影响,将海洋产业结构变动具体量化,分为海洋产业结构高级化和合理化;其次运用海洋产业全要素生产率来衡量海洋经济增长效率,通过从海洋生产函数中剔除初级要素带来的海洋经济增长效率得出海洋产业全要素生产率;同时计算出海洋产业劳动和资本的生产效率;最后收集了1996—2015年全国沿海11个省、市、自治区的数据,运用混合面板数据模型来研究海洋产业结构高级化和合理化对海洋经济增长效率的影响。研究发现海洋产业结构合理化和高级化对海洋经济增长具有正面影响,对于未来发展海洋经济提出了提高海洋产业技术来提高海洋产业结构优化,从而使得海洋经济发展走上集约式增长之路。
