不同经济发展水平下创新要素对产业创新绩效的影响及政策启示

基于不同经济发展水平研究视角，选取新一代信息技术产业为研究对象，采用改进的Griliches-Jaffe知识生产函数模型，运用面板数据回归分析方法，利用《中国高技术产业统计年鉴》（2007-2017年）中电子及通信设备制造业统计数据进行实证研究，探究创新要素投入与创新绩效的关系。结果发现：对于新一代信息技术产业，在不同经济发展水平地区投入相同创新要素对创新绩效的影响存在一定差异，尤其体现在技术投入要素作用效果上。这就意味着，对经济发展水平不同地区使用相同的创新要素推动产业创新发展是低效的；不同发展水平地区有针对性地分配创新要素，对于实现创新要素最大效率、推动战略性新兴产业布局与发展尤其关键。最后，提出相应政策启示及建议。     

会计信息价值相关性研究:国外文献评述

全面梳理会计信息价值相关性研究文献,系统评价盈余公告反应研究和会计信息估值研究成果。得出结论:现有盈余公告反应研究的主要观点是,影响盈余公告向市场传递未预期盈余信息大小的主要因素为信息披露前的环境特征,影响盈余信息含量的主要因素为未预期盈余持续性;现有关于会计信息估值的研究主要是以财务比率对未来盈利的预测能力的质量驱动研究和主要基于具体的估值模型的价值驱动研究。未来的研究应在特殊情景、估值模型的拓展以及更新研究方法方面作出努力。     

Does transparency of central banks communication affect credit market? Empirical evidence for advanced and emerging markets

This study examines the effect of the transparency of central banks communication on credit market. In particular, this study investigates how central banks’ effort to provide more detailed information about their objectives regarding the price stability (monetary policy transparency) and financial stability (financial stability transparency) policies are able to mitigate information asymmetry on credit market, through the net interest margin charged by the banks to engage in financial intermediation (credit spread). The findings denote central bank transparency is able to reduce the credit spread. Additionally, the evidence suggests the effect of central bank transparency on the credit spread is greater in emerging markets, where there is less information available on credit market. In brief, transparency in central banks communication is an important tool to mitigate the information asymmetry in the credit market.     

The effects of choice set size and information filtering mechanisms on online hotel booking

Online booking is one of the most popular ways of making reservations for hotel guests. Thus, hoteliers are paying increasing attention to hotel website information presentation and design. The purpose of this study, then, is to examine the joint influence of choice set size and information filtering mechanisms on consumers’ decision confidence towards online hotel booking. Choice set size was operationalized through 3-, 9-, and 30-hotel room choice sets. Through experimental design, this study shows that the presence of an information filtering mechanism reduces consumers’ perceptions of choice overload with a large number of choices (30 choices), whereas its impact is attenuated with smaller choice sets (3 and 9 choices). In addition, choice overload mediates the impact of choice set size on decision confidence. Theoretical contribution and managerial implications are also discussed.

Macroeconomic Announcements and the Distribution of Price-Endings in the U.S. Treasury Market

We investigate how new information impacts quote clustering in the bond market. We find that clustering, along with quote activity, price volatility and bid-ask spreads, increases sharply in the minutes following releases of macroeconomic news. Each returns to near-normal levels within the hour. Effects are strongest for more liquid on-the-run notes and for the announcements typically associated with substantial information flow. The strong positive comovement of clustering, quote activity, price volatility, and bid-ask spreads supports the conclusion that innovations of these variables are endogenous to the arrival and incorporation of information into prices.     

Information technology and consumer behavior in travel and tourism: Insights from travel planning using the internet

Sustaining business success hinges upon a firm׳s ability to understand and capitalize on consumer behavior trends. Synthesizing information from a variety of sources, this paper discusses the nature of use of the Internet by American travelers. In general, the adoption of the Internet has reached a level of saturation and some traditional channels such as online travel agencies (OTAs) continue to dominate travel planning. While traditional means of Internet use for travel planning appears to be widespread across all customer segments, higher-order Internet uses (i.e., social media) are now prevalent among some segments, particularly among travelers of Generation Y. Also, there seems to be an important bifurcation in the traveler population in that the traditional online consumers remain unchanged with their pattern of use of online tools while sizable groups are adopting emergent information sources and transaction channels. This article details the particulars of these trends and offers managerial implications and future research directions.     

Exploring the intention to continue using web-based self-service

The popularization of Internet and the development of cloud computing have not only changed our lifestyles, but have impacted the ways in which enterprises relate with their customers. For example, customers and enterprises can now directly interact through web-based self-services (e.g., Internet banking, online ticketing, online bookstores, and online reservations) that do not require face-to-face interactions. Web-based self-services (WBSS) allow enterprises to proactively initiate contacts with customers and respond to their needs. Customers can also quickly access the services they want online, at any time and place, thus enhancing overall service efficiency. However, a review of the previous literature shows that most related studies have used the Technology Acceptance Model, which examines perceived usefulness, perceived ease of use and attitude toward use, in order to investigate user behaviors when operating a WBSS. In contrast, there are few studies that examine the impact of perceived usefulness and perceived quality features on the continued intention to use a WBSS. Therefore, this study applied the questionnaire method and investigated the relationships among users’ perceived usage characteristics, quality characteristics, satisfaction and continued usage intention with regard to WBSS. Based on the results, specific recommendations are provided for enterprises to enhance the intention to continue using WBSS.     

New technology and old institutions: An empirical analysis of the skill-biased demand for older workers in Europe

Using panel data from nine European countries over the period 1970 to 2007, we examine the impact of information and communication technology (ICT) on the demand for older workers (aged 50 and over). We find evidence of a decrease in demand for older workers in the 1970s and 1980s. It can be argued that the impact of ICT on demand for older workers is skill-biased. However, the skill-biased demand for older workers is mainly reflected in the skill-biased changes in employment shares rather than relative wages. There is some evidence of a gradual deskilling of older workers. We find that labour market institutions such as the national minimum wage, social pacts on wage issues and union density mostly benefit skilled older workers, while coordination of wage setting, extension of collective agreements, social pacts on pensions and centralisation of wage bargaining can alleviate the adverse effects of skill-biased technological change.     

Advocacy and political convergence under preference uncertainty

We study the formation of advocacy groups and how they can impact policy outcomes by revealing information about voters׳ preferences to uninformed political candidates. We conduct a laboratory experiment based on a two-candidate spatial electoral competition setting where the policy preferences of voters are (initially) unknown and change over time. In the control treatment candidates learn about the preferred policy of the median voter through the voting outcome of elections. In the advocacy treatments, voters can organize themselves into advocacy groups in order to reveal their policy preferences. We find that voters often overcome the collective action problem of forming an advocacy group. In fact, we observe the formation of both informative advocacy groups, which convey new information, and uninformative advocacy groups, which do not. Overall, advocacy groups significantly speed up the convergence to the preferred policy of the median voter. However, advocacy does not lead to higher earnings as the gains from faster convergence are offset by the costs of group formation.
