内向型开放式创新、国际化、投机性学习与创新绩效的关系

组织学习过程中的投机性行为影响着企业创新绩效。运用组织学习与创新理论,从开放式创新视角阐述了国际化企业投机性学习影响创新绩效的过程机理。研究发现,高新技术企业的内向型创新模式能够提高创新绩效,但国际化程度负向调节它们之间的关系;同时,投机性学习行为削弱了内向型与创新绩效之间的正向关系,即投机性学习不利于提高内向型开放式创新绩效。研究结论对于新兴企业的开放式创新与国际化具有理论和实践意义。     

盐酸法舒地尔防治外伤性蛛网膜下腔出血后脑血管痉挛初步研究

目的验证盐酸法舒地尔治疗外伤性蛛网膜下腔出血（tSAH）后脑血管痉挛的有效和安全性。方法以尼莫地平为对照,采用开放随机对照试验,探讨盐酸法舒地尔的疗效.并进行临床安全性评估。选取经CT证实tSAH的中—重型闭合性颅脑损伤患者40例,随机分为法舒地尔及尼莫地平治疗组,同时选取未行抗血管痉挛治疗的20例tSAH患者作为空白对照。应用经颅多普勒（TCD）观察伤后48h,72h,5d,7d和12d大脑中动脉,颈内动脉血流动力学变化及1个月后的Glasgow预后评分;并对患者的重要脏器功能及迟发出血发生率进行比较。结果盐酸法舒地尔与尼莫地平都可明显降低tSAH后脑血管的痉挛程度和改善患者预后,两药物之间疗效并无统计学差异。对照组有2例外伤后继发梗塞出现,治疗组未出现类似病例。临床安全性研究发现盐酸法舒地尔对肝、肾功能均无明显影响,且不会增加迟发性颅内出血的比例。结论对于tSAH后迟发脑血管痉挛的治疗,盐酸法舒地尔是一种安全有效的药物。     

“Flying geese” in China: The textile and apparel industry's pattern of migration

China has large regional variations in both factor endowments and levels of economic development. In principle, some industrial enterprises will relocate to the inland regions from the coastal regions to take advantage of lower wage rates and land prices, provided that the regions are different enough. However, few studies have empirically tested whether this kind of “flying geese” pattern of domestic industrial relocation has occurred on the ground or not. Using data from the textile and apparel industry from 1998 to 2011, this paper shows the existence of the “flying geese” pattern of industrial relocation. Data show that before around 2005, the textile and apparel industry was clustered in the eastern region of China, but it has since shifted toward the central and western regions.     

Optimal auctions with asymmetric financial externalities

This paper studies optimal auction design with asymmetric linear financial externalities among bidders. When the matrix Γ that relates bidders? payoffs to their payments is nonsingular, the payment-related component in the design objective must equal a unique linear combination of its counterparts in bidder?s payoffs. If all multipliers of the linear combination are nonnegative, a modified Myerson procedure is discovered for deriving the optimal design. If any multiplier is negative, an arbitrarily high value can be achieved for design objective by setting proper fixed transfers to bidders. When the matrix Γ is singular, the unbounded optimum result typically prevails. We applied our method to auctions with cross shareholdings and charity auctions for revenue-maximizing and efficient designs.     

Decision making for urban solid waste treatment in the context of territorial conflict: Can the Analytic Network Process help?

There are a number of factors that affect decisions concerning the so-called undesirable facilities such as waste treatment technologies or landfills. These include social opposition and the need for a huge number of social, economic and environmental data to be taken into account. In Italy (as in many other developed nations) any decision to draft a plan or to define the choice of location for an undesirable service requires an immense amount of discussion, negotiation and organization. This usually occurs in open public debates organized by the local Administration. Another obstacle to the government of the territory is transaction costs which are growing out of proportion. In a situation of high institutional and social fragmentation, the power of veto is in fact multiplied.This paper reflects on the potential of the MCDA to help Decision Makers with particular reference to the involvement of the stakeholders, which face and disclose all the elements stopping or affecting the choice. The case study presented concerns the current debate about the best choice for the treatment of municipal solid waste in the Aosta Valley region, a small independent region in the North-West Italy. The Analytic Network Process is applied in order to rank three alternative technologies for waste treatment (namely mechanical biological treatment, incineration – direct combustion – and gasification) and to identify the priority ranking between the elements under examination (namely environmental, social, economic and technological aspects).     

Wages,fringe benefits and worker turnover

Linked employer–employee data from Norway are utilised to study how employers use wages and fringe benefits in managing their workforce. The analysis shows that on average across all establishments, we observe a positive correlation between wages and fringe benefits. This indicates the presence of labour market frictions and thus is not supportive of the classical frictionless hedonic wage model. Higher wages and more fringe benefits reduce the worker turnover rate. Fringe benefits have stronger negative impact on the excess worker turnover rate than indicated by the reported monetary value.
