Taxation and labour supply: Evidence from a representative population survey

We study how taxation influences labour supply using a specifically designed representative survey of the German population. First, we investigate whether taxes generally matter for the labour supply decisions of our respondents. Around 41 per cent report taking taxes into consideration, implying that the majority of the German population is unresponsive to taxation. Second, we look at self-reported labour supply adjustments following a recently enacted payroll tax change. Only around 12 per cent of our respondents report an actual labour supply response, but we find evidence of an income, as well as a substitution, effect of the tax change. Our conclusion is that the effects of taxes on labour supply in Germany are likely small. We analyse the correlation with economic and socio-demographic variables and find that the self-employed are relatively more sensitive to taxation and that low interest rates reduce incentives for expanding the labour supply.     

Dynamic road lane management study: A Smart City application

Our Smart City contribution is transportation-oriented in that it proposes a dynamic road lane management system in order to share appropriately the space devoted to traffic. After a historical view of a series of solutions from physical to ICT supported, we present our proposal extensively supported by up-to-date ICT. Following a main presentation, we describe the system architecture and its working conditions. Then, we present the proposed simulator designed to study operating and driver’s conditions with respect to the new traffic signs proposed. We also describe a Mock-up technology validation and give preliminary information on in-the-field deployment.     

Innovation Portfolio Management as a Subset of Dynamic Capabilities: Measurement and Impact on Innovative Performance

Innovation portfolio management has been touted as a new dynamic capability following the evolution of team‐ and project‐based organizational forms. In this article, we conceptualize innovative dynamic capabilities as a multidimensional construct that comprises distinct but related aspects in managing innovation. We test our model, which links this capability to innovative performance by using survey data from a sample of 923 firms. We find empirical support for our conceptualization and its impact on firm innovative performance.

Tourist adaptation behavior in response to climate disasters in Bangladesh

To assess the impacts of climate disasters on the behavior of tourists in Bangladesh, this study makes an initial attempt to investigate tourists’ adaptation behavior in response to climate disasters. A questionnaire survey was developed and administered to address both tourists’ previous adaptation behavior and their stated adaptation behavior in response to different future climate disasters. The choice modeling analysis of tourists’ previous behavior revealed that a cyclone is more likely to result in the cancellation of a trip, and a flood is more likely to result in a change in trip timing. As for the stated behavior analysis, it was confirmed that most variables related to disaster severity show significant influence on adaptation behavior. The results also indicate that construction of disaster-resilient transportation networks is essential to avoid trip cancellations. In addition, improving market-oriented tourism service quality in Bangladesh could play a significant role in reducing the probability of both trip cancellations and changes of destination. The findings of this study can provide the tourism industry in Bangladesh with critical insights for future disaster management and sustainable development of the tourism industry.     

Measuring Prices and Price Competition Online: Amazon.com and BarnesandNoble.com

Despite the interest in measuring price sensitivity of online consumers, most academic work on Internet commerce is hindered by a lack of data on quantity. In this paper we use publicly available data on the sales ranks of about 20,000 books to derive quantity proxies at the two leading online booksellers. Matching this information to prices, we can directly estimate the elasticities of demand facing both merchants as well as create a price index for online books. The results show significant price sensitivity at both merchants but demand at BarnesandNoble.com is much more price-elastic than is demand at Amazon.com. The data also allow us to estimate the magnitude of bias in the CPI due to the rise of Internet sales.     

网络文化对大学生影响的现状及对策

伴随着计算机技术的发展而兴起的网络文化已深入到高等院校，并产生了极其广泛的影响，无论是大学生的学习方法和途径，还是他们的思维方式，无论是大学生人际交往的手段，还是他们的娱乐方式以及价值观念都无一例外。网络文化既给我们带来新方法，新观念和新文化，但同时也不可避免地带来诸多新的困惑，这就为高校政治思想工作提出了新挑战，因此我们必须用带有前瞻性的光来审视这一新变化，也必须具有新的措施来应对它的挑战。

Consumer use of the internet for health information: a survey of primary care patients

An increasing number of patients use the internet to obtain information about health. Although some information is available about how health professionals use the internet, little is known about how patients utilize this information. Some patients may actively seek information to assume more responsibility for their health. However, others may feel obliged to do so because of failing confidence in health care provision. Health professionals have the potential to assist patients to make sense of health information from the internet; however, they may not necessarily welcome this role. This study aims to evaluate patients’ use of such information in a primary care setting. The sample consisted of adult patients (n = 851) from two general practice populations at different levels of the socio‐economic spectrum in South Wales (UK). Patients were surveyed by questionnaire about the health information they use, including the internet. The majority of patients preferred to use their general practitioner as the main source of health information. The internet was jointly the second preferred source for information about an illness (6%). Just over half (51%) of patients in this study had access to the internet, of which about half use it to access health information. Just under a quarter (24%, n = 55) of health internet users had discussed information accessed from the internet during a subsequent consultation with a health professional. Of these, three‐quarters felt more prepared and able to participate in decision‐making about treatments. This study provides a greater understanding of how patients are making use of health‐related information from the internet. These findings can be used to help prepare health care professionals for dealing appropriately with internet‐informed patients.     

Automobiles: The Old Economy Collides with the New

The U.S. automobile industry is beginning to confront the next major technology – the internet. Business-to-business manufacturing systems and supply exchanges, together with business-to-consumer ordering and purchase systems, all have the potential to bring great efficiencies to this traditional industry. But each of these innovations raises new competitive issues. Internet ordering will greatly diminish the role of conventional dealers, who have thus far blunted its impact. B2B exchanges raise concerns about buyer power and other competitive effects. This paper outlines and analyzes these internet-drivenchanges and their competitive implications for the industry, its dealers, suppliers, and customers.
