The gender wage gap in Austria: eppur si muove!

We examine the change of the gender wage gap in Austria between 2002 and 2007 using Juhn et al. (Workers and their wages, AEI Press, Washington DC, pp 107–143, 1991) decomposition. We analyze data from Austrian tax records which we merge with social security records and Austrian micro-censuses of the years 2002 and 2007. We find that the gender wage gap declined from 21 % in 2002 to 18 % in 2007. The main determinant of this decline is the relative improvement of women’s unobserved characteristics. The decline of the gender wage gap is also due to women having attained more formal education and to a convergence of men’s and women’s returns to education. Women’s improved educational attainments were partly offset by a shift in the demand for skilled workers that disadvantaged unskilled workers, most of whom are women, resulting in a moderate decrease of the gender pay gap over these years. Robustness checks confirm our results.     

中国制造业上市公司创新行为对企业技术效率的影响研究

以2006-2008年的51家制造业上市公司为样本,运用DEA-Tobit模型,分别检验了研发投入和专利产出对企业技术效率的影响。实证结果表明:R&D经费投入对技术效率具有显著的积极影响;研发人员投入对技术效率的当期效应和长期效应均为正相关,但只在累积效应模型中通过了显著性检验;发明专利对样本企业的技术效率具有显著的积极影响,并具有明显的滞后性;实用新型专利对样本企业的技术效率具有显著的负效应,同时存在明显的滞后性;外观设计专利对样本企业的技术效率具有负效应,但不显著。结果启示,可以通过制定合理的研发战略来提升企业的自主创新能力,这是企业提高技术效率的重要途径之一。     

保本型股票挂钩结构性外汇理财产品定价研究

内容本文首先针对单资产股票挂钩保本型结构性产品的期权特性,在一定的假设前提下,根据风险中性定价原理,借鉴Black-Scholes期权定价方法,对受汇率波动影响的外汇理财产品进行定价研究,并得出定价公式,然后运用中国民生银行非凡理财第四期的两年期产品为案例进行定价分析,结果表明该产品收益率设计是合理的。

以利用wos数据库检索到的、发表于1997—2013年期间的、关于跨国并购的643篇英文文献为数据源,利用动态网络分析软件Citespace,通过作者共引分析确定了企业跨国并购研究领域中的知名学者,通过文献共引分析确定了企业跨国并购研究的理论基础,并分析理论发展规律。进一步分析得到目前跨国并购研究领域的高频主题词,包括文化、银行跨国并购、汽车产业、进入方式、战略联盟、法律、知识转移、贸易保护、中国企业、中国、学习能力、国家文化等。最后,结合实际,为跨国并购研究的进一步开展提供了参考建议。     

An Eclectic Approach to Estimating U.S. Potential GDP

Rennison (Comparing alternative output gap estimations: a Monte Carlo approach, 2003) has provided simulation-based evidence showing that the joint use of extended multivariate filters and structural vector autoregression models is optimal for estimating potential output. We use this approach to estimate the two components of potential GDP: the full-employment labour input and trend labour productivity. This decomposition is useful for identifying sources of fluctuations in potential output. It reveals, for example, that the vigorous growth rate of U.S. potential GDP recorded during the second half of the 1990s is attributable to a fall in the structural rate of unemployment and a marked upswing in trend productivity growth.     

The impact of the Internet on human activity–travel patterns: analysis of gender differences using multi-group structural equation models

The widespread use of the Internet for conducting various types of activities may be leading to considerable change in people’s activity–travel patterns. Past studies, however, have left many issues unaddressed. Using an Internet-activity diary dataset and multi-group structural equation modeling, this study examines the complex interactions between different types of Internet and physical activities, with a special focus on gender differences and Internet maintenance and leisure activities. The results indicate that the impacts of Internet activities on people’s activity–travel patterns are significantly different across gender. In general, Internet use for maintenance purposes has a greater impact on women’s activity–travel in the physical world, while Internet use for leisure purposes affects men’s physical activities and travel to a greater extent. Further, breaking Internet activities down into different categories reveals some hidden patterns that would not have been detected if these different types of Internet activities were lumped together as a single category.
