Smallholder Demand for Maize Hybrids in Zambia: How Far do Seed Subsidies Reach?

We add to an emerging body of literature on input subsidies in Africa south of the Sahara. Our analysis focuses on demand for seed, characterising smallholders with a high predicted demand for hybrid seed who were not reached by the subsidy programme. We use cross‐sectional data from the 2010 agricultural season and an instrumented control function approach to test the hypothesis that the subsidy on hybrid maize seed in Zambia is selectively biased. Consistent with other literature, we find that the subsidy is a recursive determinant of seed demand, but in 2010, its recipients had more land, more assets, and lower poverty rates. Findings illustrate the social costs of the programme as currently designed and highlight the need to build alternative supply channels if poorer maize growers are to grow hybrid seed.     

Price integration in the Australian rock lobster industry: implications for management and climate change adaptation

Rock lobster fisheries are Australia's most valuable wild fisheries in terms of both value of production and value of exports. Different states harvest and export different lobster species, with most of the landings being sent to the Hong Kong market. A perception in the Australian lobster industry is that the different species are independent on the export market, such that a change in landings of one species has no impact on the price of the others. This study investigates the market integration of Australian exports to Hong Kong for the four species and different exporting states. Our results indicate all four species and producers/export states are perceived to be substitutes for one another, so that, in the long run, prices paid to operators in the industry will move together. The integrated nature of the Hong Kong export market for Australian lobster suggests that the potential impacts of alternative fisheries management and development strategies at state and species levels cannot be considered in isolation, at least from an economic perspective. In addition, impacts of external shocks affecting production in one state (e.g. climate change) can be expected to affect all Australian lobster fisheries.     

中国证券市场各类风险对资本成本的影响研究

以2007-2010年我国A股上市公司为样本,用Hanlon改进的剩余收益增长率方法度量资本成本,并在此基础上从微观结构视角分析证券市场中最主要的系统波动性风险、特质波动性风险、流动性风险和信息风险对资本成本的影响。结果发现,随着系统波动性风险、流动性风险以及信息风险这三类传统意义上的系统性风险增大,资本成本也增大;通过投资组合部分分散的特质波动风险则与资本成本的关系不明确。     

旅游产业集聚与区域经济耦合关系研究

随着我国社会的不断发展和人们生活水平的不断提高,旅游产业在我国也占据了重要地位。此时,各个旅游产业之间的紧密合作已经成为促进区域经济发展的首要方式。由此可见,旅游产业的集聚与区域经济的发展存在着相互促进、相互带动的关系,在经济发展较好的区域才会不断发展出更多旅游产业,而在旅游产业不断扩大的情况下才会使当地的经济发展得到进一步提高,因此,旅游产业与当地的区域经济发展是相互依存的。本文通过理论和实证的相互结合对旅游产业与区域经济耦合关系以及影响旅游产业和区域经济发展的因素进行深入探讨和剖析,为今后对旅游产业及区域经济发展的配合管理提供一定的借鉴。     

解读信息公开对现代行政权正当性的证成——以杭州市政府开放式决策为例

信息公开的制度价值并不限于监督依法行政与保障信息获取权。以杭州市政府开放式决策实践为观察样本,其将《政府信息公开条例》中对公众广泛知晓并参与重大事项的保障作为制度基点,构建了吸纳多元意见的信息渠道,将公众的直接参与导入政府的日常决策。开放式决策模式的实质目的在于证成现代行政权的正当性。在开放式决策的视角下,信息公开正是以充分主动公开作为参与的前提、以保障申请公开获得更广泛的决策认同、以互动协商促进决策结果合理化的多维视角化解现代行政权的正当性危机。把握信息公开重塑现代行政权正当性的关键作用,重新认识信息公开的制度价值理念,将促进行政机关更为主动、积极地回应信息公开。     

灰色关联分析法在重大错报风险评估中的应用研究

重大错报风险的形成原因错综复杂,如何评价风险可能存在的业务领域、风险相对高低以及被审单位整体重大错报风险大小是实施现代风险导向审计的三大核心和难点。首先构建重大错报风险综合评价指标体系,进而引入灰色关联分析评估模型,以更加客观准确地确定各错报风险因素的权重及排序,最终得出各业务领域评估值及综合评估值大小,这样可以为会计师事务所进行单项及不同审计业务之间的资源配置提供依据。

Introducing OMOV: The Labour Party–Trade Union Review Group and the 1994 Leadership Contest

Most scholars conclude that the introduction of one member, one vote (OMOV) into the electoral college that chooses the Labour leader demonstrates a new, reduced role for the party's affiliated trade unions. This article examines the adoption of OMOV by Labour. It looks at discussions in the Labour party–trade union review group that moulded the decision to adopt OMOV during 1992–1993. Drawing on the full breakdown of results, it goes on to examine the outcome of the 1994 leadership contest. The distribution of votes, union by union, indicates that, contrary to the conventional view, trade union leaderships retained the capacity to shape the pattern of voting through their ability to nominate candidates. The article concludes that the introduction of OMOV did not reduce the role of trade union leaderships in Labour's internal affairs in the manner that many scholars have concluded to be the case.
