Over 90 percent of companies are estimated to use IT Service Management (ITSM) frameworks, yet there is little research on
their benefits to the Information Technology (IT) department and the business units. An international survey of 491 firms
was conducted to assess the benefits of the IT Infrastructure Library (ITIL), the de-facto ITSM framework, specifically on
how these benefits evolve as companies increase their adoption of the ITIL model. Also studied are the perception of challenges
of the implementation and the number of ITIL processes implemented in relation to the progress of the adoption of ITIL. Results
indicate that as the maturity of implementation increases, the perception of challenges decreases. Findings also show that
as the maturity of implementation increases, the number of realized benefits increases, as well as the number of implemented
ITIL processes. Implications for practitioners and researchers are also discussed. 相似文献

The fair use flat rate is a promising tariff concept for the mobile telecommunication industry. Similar to classical flat
rates it allows unlimited usage at a fixed monthly fee. Contrary to classical flat rates it limits the access speed once a
certain usage threshold is exceeded. Due to the current global roll-out of the LTE (Long Term Evolution) technology and the
related economic changes for telecommunication providers, the application of fair use flat rates needs a reassessment. We
therefore propose a simulation model to evaluate different pricing strategies and their contribution margin impact. The key
input element of the model is provided by so-called discrete choice experiments that allow the estimation of customer preferences. 相似文献

The paper examines the current state of research as regards the eXtensible Business Reporting Language (XBRL) by using the
literature review methodology. The results show that an empirical-quantitative research design is used most of the time. The
contributions vary in substance in terms of research on XBRL and research with XBRL. Research with XBRL focuses on the development
of conceptual XBRL extensions. Work on XBRL considers, for example, the changes in reporting as a result of XBRL as well as
the acceptance and enforcement of financial reporting standards. The results point to open issues and are relevant for research
and practice. 相似文献

In this article, we have used a continuous EBIT-based model to study deferred tax liabilities under default risk. Quite surprisingly, default risk has been disregarded in research on deferred taxation. In order to underline its importance, we first calculated the probability of default, over a given time period, together with the contingent value of tax deferral. We then applied our theoretical model to a sample of 27,749 OECD companies. We showed that, when accounting for both firms with a negative EBIT and firms with a probability of default higher than 50% (over a 10-year period), a relevant percentage of firms were close enough to default. Hence, the expected present value of deferred taxes is much lower than that obtained in a deterministic context. From the Government’s point of view, deferred tax liabilities are a risk-free loan. Since only a portion are subsequently repaid, the Government should account for future losses due to companies’ default. So far, these estimates have been missing, although techniques do exist and are quite practical. 相似文献

Existing studies of market orientation have hypothesized that the strength of the market orientation/performance relationship
depends on environmental variables such as market turbulence, technological turbulence, and competitive intensity. To date
most empirical studies have failed to confirm these hypotheses; however, these studies (1) assumed that performance is a linear
function of the achieved level of market orientation and (2) tested whether environmental uncertainty moderates this relationship.
A complementary explanation for the impact of environmental variables on a firm’s market orientation arises from studies of
organizational behavior that link the need for coordination and control to environmental uncertainty and organizational strategy.
Building on this perspective, the authors argue that (1) environmental uncertainty influences the desired level of market
orientation and (2) the gap between the desired and achieved levels of market orientation influence business unit performance.
The authors test these hypotheses with data collected from multiple respondents in 308 US firms. The data analysis confirms
that the desired level of market orientation is a function of market turbulence, competitive intensity, technological turbulence,
and innovation strategy. In addition, the desired level of market orientation positively influences the achieved level. Finally,
when the achieved level of market orientation is less than the desired level, business unit performance is a negative function
of the gap between the desired and achieved levels of market orientation.
