This paper examines the effects of the Economic and Monetary Union on demand for foreign reserves. The traditional theory on demand for international reserves assigns a pivotal role to imports. However, in a currency union part of imports are settled in the common currency, leaving no incentive for keeping foreign reserves. Moreover, the pooling of the demand for reserves in the currency union and an increasing role of a currency as an international reserve currency may also influence, among other things, the union demand for reserves. Based on estimated demand functions for reserves it is shown that the Economic and Monetary Union has reduced the demand for reserves substantially. It is argued that an enlargement with new member countries of the European Union will result in further savings of reserves. A simple calculation at the end of the paper illustrates the welfare gain associated with the reduced need of reserves in the Economic and Monetary Union.  相似文献

This paper examines the impact of foreign firm entry on the industry consolidation process in a host country that operates through mergers and exits of incumbent firms. Using a three-stage oligopolistic model, the paper shows that foreign direct investment (FDI) may trigger consolidation via a merger since the approval of a domestic merger by the antitrust authority is more likely in the case a foreign firm enters via FDI and a firm’s incentive for a domestic merger is greater and that, in turn, the possibility to merge and become more efficient modifies the outcome of the game by making FDI compared to exports less likely.  相似文献

This study highlights the importance of market orientation and the use of information and communication technologies (ICT) as determinants of service innovation activity for companies in the tourism sector. In doing so, the study provides a means to classify companies as innovative or not. Using a sample of 100 Spanish firms from different branches of the tourism sector, we confirm and extend prior research. In particular, market orientation??especially a customer orientation??is critical for developing new services that lead to competitive advantages. In addition, ICT have a dual, direct, and indirect influence on service innovation.  相似文献

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

Empirical Evaluation of Fair Use Flat Rate Strategies for Mobile Internet   总被引:2,自引:1,他引:1  
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
