全球价值链视角下我国远洋渔业国际竞争力影响因素研究

文章基于全球价值链视角,结合远洋渔业的产业特性,构建了远洋渔业国际竞争力概念框架及其影响因素理论模型。进而基于我国74 家远洋渔业企业的问卷调查横截面数据,运用多元回归分析,深入解剖了影响我国远洋渔业经济租金、国际话语权、国际在位权、企业就业贡献四个国际竞争力维度的影响因素。研究发现：（1）远洋渔业企业越是进行海外远洋渔业基地建设、基地建设功能越健全,水产品国内消费市场越兴盛,远洋渔业企业冷冻、冷藏等储藏能力越强,企业越是能获得持续盈利优势。（2）远洋渔业设备技术研发、远洋渔业金融政策、政府间远洋渔业争议协商机制和海上通信系统研发,有助于提高我国远洋渔业国际组织影响力。（3）企业船上加工技术、企业水产品出口能力、海外直接投资正向显著影响企业履约能力。（4）企业远洋渔船规模、企业有自己独特的海洋与岸上联动发展模式,促进了企业社会就业贡献。     

A reexamination on the effect of bank competition on bank non-performing loans

This article examines whether competition in the deposit and loan markets results in a more stable or fragile banking industry. Following the assumption that deposit and loan competitions are not separable, a simple equilibrium model is developed. Then, using the aggregate time-series data of Federal Deposit Insurance Corporation (FDIC)-insured financial institutions, we estimate the generalized VAR model of deposit rate (DR), interest margin between the loan and DRs, and non-performing loan ratio. Our results support the competition–fragility hypothesis.     

Mortgage product diversity: responding to consumer demand or protecting lender profit? An asymmetric panel analysis

This article explores determinants of mortgage product diversity for owner-occupied and investment loans in the Australian housing mortgage market. From 2001 to 2012, 65 lenders introduced 1220 mortgage products in Australia. We examine whether the product proliferation was a result of consumer demand or a response to pressure to lower lending rates. We find that consumer demand for mortgages does not have a significant relationship with the number of mortgage products, but that decreases in the policy interest rate are highly significant as an explanatory variable for product proliferation. Such behaviour is consistent with information obfuscation, reducing the ease with which consumers can compare lending rates. Further, the relationship between mortgage products offered and the policy interest rate is asymmetric: decreases in the cash rate are associated with increased mortgage products offered, but increases in the cash rate have a more muted effect on decreasing the number of products.     

False claims in politics: Evidence from the US

In this paper, we use data on 2459 public claims made by 444 politicians from the leading US fact-checking site (PolitiFact) to provide an empirical analysis of false claims in politics, shedding light on their characteristics within an advanced democracy. The frequency of falsehoods differs according to party affiliation and topic, with false claims more likely on such topics as elections, health, labor, taxes and values. For Republican politicians, falsehood pays off in the short run, as it is associated with greater political support.     

What are the determinants of hiring? The importance of product market demand and search frictions

In this article, we study the importance of product market demand and search frictions for hiring. We use a search-matching model with imperfect competition in the product market to derive an equation for total hiring in a local labour market, and estimate it on Swedish panel data. If product markets are imperfectly competitive, product demand shocks should have a direct effect on employment for given levels of prices and wages. Our main finding is that product demand has such a direct effect on hiring. This highlights the importance of taking imperfect competition in the product market into account in studies of employment dynamics and hiring. We also find that, for given levels of prices, wages, and product demand, the number of unemployed workers in a local labour market has a positive effect on hiring, suggesting that search frictions matter. Quantitatively, product demand shocks seem to be more important for understanding the variation in hiring than shocks to the number of unemployed workers.     

Enhancing the teaching of introductory economics with a team-based,multi-section competition

The authors describe a unique approach to enhancing student learning at the introductory economics level that utilizes a multi-section, team-based competition. The competition is structured to supplement learning throughout the entire introductory course. Student teams are presented with current economic issues, trends, or events, and use economic tools and theories to comprehensively examine the topics. Students present their analyses in their own sections with one team from each section moving on to compete in an inter-section round. Students are judged on technicality, creativity, and applicability of economic concepts. The competition has the potential to advance students' creativity, collaboration, communication, and critical and analytical thinking skills, while enhancing their ability to apply foundational economic concepts to real-world settings.     

双重古诺竞争下的FDI关联溢出效应

扩展了以往理论研究的基本假设,在古诺竞争框架下分析FDI进入东道国上下游双边市场时的关联溢出效应。结果显示:当FDI仅进入东道国的下游市场时,FDI产生的竞争效应会增加下游市场的总产出,从而增大对上游市场中东道国本土供应商的后向关联程度,且其增大程度与技术差距正相关;在FDI同时进入东道国上下游双边市场的情况下,上游市场的FDI会对东道国本土供应商产生挤出效应,且两者的技术差距越大,挤出效应越明显,同时会对下游市场中的东道国本土生产者产生明显的前向关联,上游市场总产出的增加使得中间产品的均衡价格下降,直接减少了下游本土生产者的边际生产成本,从而增加了其产出和利润,部分抵消了下游市场的FDI的挤出效应。     

Do banking system transparency and competition affect nonperforming loans in the Chinese banking sector?

The increasing importance of transparency practices and the improving status of bank competition in China are rarely explored in nonperforming loans (NPLs) literature. Thus, the purpose of this study is to examine banking system transparency and competition along with macroeconomic and bank-specific variables as determinants of NPL. We use the two-step system GMM dynamic panel model for Chinese banks based on annual data from 2000 to 2014. Our results indicate that high transparency in the Chinese banking system decreases poor-quality assets but not in the case of government-owned banks, whereas increase in competition increases NPL. Moreover, we find mixed results in the context of macroeconomics and bank-specific variables. Our study has practical implications in risk management practices and macro prudential policies.     

The quest for publicness: political conflict about the organisation of tramways and telecommunication in Sweden,c. 1900–1920

This article explores political conflicts about the organisation of public services in Sweden c. 1900–1920. The authors argue that political decisions play a vital role in shaping the political economy of public services. The case studies analysed are the political debates about the communalisation of the tramway system in Stockholm, and the nationalisation of Sweden’s last private telephone company. In both cases, the transfer of the service to public organisation was a lengthy process, ending in the late 1910s. This is explained using the concept of publicness. Drawing on three discursive chains, the argument is that the political development was affected by the politicians conception of the political community, the form of organisation and by perceptions of values such as equal access and modernity. In the case of the tramways, public organisation was seen as the best option to defend the public against corruption and self-interest. In the case of the telephones, free market competition was seen as a guarantee for an efficient and cost-effective service. The reason for this difference, is argued, was that the debate on the tramways articulated a clearer notion of publicness, where equal access and public opinion carried larger weight.     

制造传统——关于傣族泼水节及其相关新年话语的研究

有关泼水节即傣历新年的说法在当代学术界已成定论。然而,为什么这一节日庆典的日期不在傣历的一月一日？对此,既有研究并未给出令人满意的解释。在对相关文献进行梳理和作者本人田野研究所得发现的基础上,本文提出了自己的看法,认为泼水节并非傣历新年,而是佛教新年和傣族远古泼水习俗两个来源的结合体。继而,作者指出,被视为傣历新年的泼水节实际上是一种被制造出来的传统。
