The optimal multi-stage contest

This paper investigates the optimal (effort-maximizing) structure of multi-stage sequential-elimination contests. We allow the contest organizer to design the contest structure using two instruments: contest sequence (the number of stages, and the number of contestants remaining after each stage), and prize allocation. When the contest technology is sufficiently noisy, we find that multi-stage contests elicit more effort than single-stage contests. For concave and moderately convex impact functions, the contest organizer should allocate the entire prize purse to a single final prize, regardless of the contest sequence. Additional stages always increase total effort. Therefore, the optimal contest eliminates one contestant at each stage until the finale when a single winner obtains the entire prize purse. Our results thus rationalize various forms of multi-stage contests that are conducted in the real world.     

资本约束对我国上市银行资产配置行为的影响

选取2004～2011年中国上市商业银行财务数据,研究资本约束对我国上市商业银行资产配置行为(主要是信贷资产配置行为)的影响。本文发现,自2004年中国资本监管制度实施以后,上市商业银行的资产规模不断增长,贷款占总资产比率呈下降趋势,资本充足率和所有者权益占比呈上升趋势;但是回归分析发现资本约束对我国上市商业银行资产配置行为的影响有限。     

The impact of market freedom on the adoption of third-party electronic marketplaces: A fuzzy AHP analysis

Electronic-marketplace (EM) is an innovative model for interfirm transactions that are undertaken via the Internet. However, in view of higher investment costs and other associated risks, many small and medium-sized enterprises (SMEs), instead of establishing their own EMs, turn to adopt third-party-hosted EMs. In literature, most relevant studies to the adoption of the third-party-hosted EM were conducted on the research contexts of free market. Industries under the protection of government policies may have limited degree of market freedom, different from industries without these protection policies. Thus, this study intends to compare the decision choice of EM adoption between industries with various degree of market freedom. The decision choice of EM adoption consisted of many strategic factors that were constructed in terms of a three-layer hierarchical structure proposed in this paper. A fuzzy analytic hierarchical process (Fuzzy AHP) was utilized to estimate the relative importance of these individual strategic factors involved in the decision-making process of adopting third-party EMs. The research findings indicated there were some similarities and differences in the decision choice between the two industries of interest. The variety of market freedom can account for the differences in the decision choice of EM adoption. In addition to enhancing our understanding of the EM adoption decision of participative companies, the research findings also provide insightful information to third-party EM providers so that they may improve the effectiveness and efficiency of resource allocation.

An Average Derivative Estimation of Stochastic Frontiers

This paper utilizes the average derivative estimation of Stoker (1986) and the pesudo-likelihood estimation of Fan, Li, and Weersink (1996) to estimate a semiparametric stochastic frontier regression, y = g(x) + , where the function g(.)is unknown and is a composite error in a standard setting. The proposed semiparametric method of estimation is applied to data on farmers' credit unions in Taiwan. Empirical results show that the banking services of the farmers' credit unions is subject to economies of scale, but high degree of cost inefficiency in operation.

社会福利制度与资本主义国家政府合法性的限度

长期以来,资本主义国家一直努力通过实施社会福利制度获取政府合法性,从社会群体结构来看,政府合法性的本质是精英与大众对政府运用公共权力主导社会利益分配的结果是否能够取得共识。这就要求政府通过社会福利政策在精英与大众之间取得配置利益的均衡,即在两大社会群体之间达成合作博弈均衡。然而,资本主导的社会积累与民主主导的社会和谐之间的不可调和的矛盾,决定了这两大社会群体之间的合作性均衡是脆弱的,也最终决定了资本主义国家的政府合法性是有限度的。     

我国大豆贸易的现状及其影响分析

文章认为,我国自加入世界贸易组织以来,大豆贸易逆差越来越大。大豆进口量的逐年增长已经对我国大豆的本地种植带来了极大的负面影响,由此引发的有关大豆上下游产业也受到了相当大的冲击。从长远看,这些影响会对我国大豆的相关产业安全带来威胁。为此,文章呼吁我国应从产业安全的战略高度出发,针对大豆产业链的各个环节制定出相应对策,以有效保护我国大豆产业健康发展。     

浅析垃圾焚烧炉排炉高温过热器防腐

通过对生活垃圾成分的分析,说明在焚烧过程中产生的HCl等酸性气体,是造成垃圾焚烧炉高温腐蚀的主要原因。对其燃烧工况及锅炉的金属受热面产生腐蚀的原因进行了分析,并提出了防止和减缓高温腐蚀的措施。认为,在垃圾焚烧炉过热器上涂耐腐蚀高温涂料和加装防磨罩可以防止或减缓腐蚀。
