The Euro and Internal Economic Policy Coordination   总被引:1,自引:0,他引:1  
This paper reviews, mainly from an institutional angle, the objectives, forms, scope, levels, implementation and challenges involved for internal economic policy coordination after the introduction of the euro on 1 January 1999. In particular, it identifies six different aspects of coordination (procedures, exchange of information, analytical framework, monitoring, policy interactions and joint determination of policies) and analyses the rationale for coordination in eight different policy areas. After presenting some of the challenges lying ahead, the paper concludes that although an appropriate institutional framework seems in place, it still has to undergo its baptism of fire.  相似文献

Abstract

Objective:

We developed and evaluated the psychometric properties of the Diabetes Therapy-Related QOL (DTR-QOL) as a disease-specific, self-administered questionnaire to assess the influence of diabetes treatment on patient QOL, regardless of treatment method.

Methods:

This new questionnaire was developed and validated in a standardized manner: Item development, pilot-testing and psychometric validation. A survey was conducted using the provisional version of the questionnaire, and reliability and validity were evaluated with psychometric testing.

Results:

The provisional version of the questionnaire was generated with 29 items through literature review and pilot testing. For psychometric assessment, analyses were performed on the responses of 284 adult Japanese patients with diabetes. Factor analysis by the principal factor method with promax rotation revealed 4 factors; “burden on social activities and daily activities” (13 items), “anxiety and dissatisfaction with treatment” (8 items), “hypoglycemia” (4 items), and “satisfaction with treatment” (4 items). For reliability, the intraclass correlation was 0.92, and Cronbach’s alpha coefficient was 0.94, indicating adequate test-retest reliability and internal consistency. For known-group validity, there were significant differences in scores for following variables: age, diabetes type, HbA1c, treatment method, glycemic control, hypoglycemia, nocturnal hypoglycemia, concern about weight gain, health status (patient assessment), and degree of communication with physician.

Conclusions:

The DTR-QOL, with good reliability and validity, can assess the influence of diabetes treatment on patient QOL. The DTR-QOL can be used regardless of treatment method that patients receive, and this characteristic enables to detect a difference on patients QOL between treatment methods before and after a switch of treatment. Limitations of this study include representativeness of the patient sample. The relatively small number of patients with type 1 diabetes should be noted. Also, responsiveness of the DTR-QOL has not yet been examined.  相似文献

The importance of cloud computing is acknowledged both at national and entrepreneurial level. Its potential in business has been already described in many studies (Dillon et al., 2010; Bayrak et al., 2011; Nuseibeh, 2011; Repschlaeger et al., 2013). However, many European countries do not exploit it much in spite of many positive responses made by respected consulting companies. The reasons for this are a very low level of changes in companies, ignorance of opportunities of the given technology and, consequently, an inability to count the return of investment. Therefore, the aim of this article is to introduce a tool for the investment evaluation of cloud computing, which corresponds to the needs of the European business environment and to the properties of this technology. Furthermore, the cost Benefit Analysis (CBA) method is explored. This method is adjusted for cloud computing on the basis of companies’ requirements, which were collected from quantitative and qualitative surveys and from the interviews with experts in cloud computing from academic and business environments. In addition, individual stages of the CBA method used in cloud computing are described.  相似文献

This paper investigates theoretically and empirically the heterogeneous response of exporters to real exchange rate fluctuations due to the quality of imported inputs and exported output. We develop a model where the production of high-quality products requires high-quality inputs sold in monopolistically competitive foreign markets. The model predicts that exporters using imported inputs have low exchange rate pass-through, but this effect is weaker for firms shipping high-quality goods. This is due to the heterogeneous price adjustments of foreign suppliers selling inputs of different quality. We test the predictions of the model using Italian firm-level trade data for the period 2000–2006. The empirical analysis shows that the imports of intermediates have a significantly weaker effect in reducing the exchange rate pass-through into the export price of high-quality varieties. By showing that the import price of high-quality inputs is less sensitive to exchange rate variations, we provide evidence supporting the theoretical hypothesis that the pricing power of input suppliers weakens the import channel.  相似文献

We combine contingent behaviour with travel cost data to estimate the change in the recreational use value of a National Forest due to quality and price changes. Instead of the usual improvement scenario, a hypothetical deterioration in the conditions of the forest due to a fire is considered. A dataset containing five observations for each respondent enabled the estimation of three models for which the number of scenarios differed. The results show that visitors are sensitive to price and quality changes and that in the forest fire scenario the intended number of trips would be reduced and that respondents would experience a welfare loss. Signs of inconsistency between preferences expressed by revealed and intended behaviour were found. This research also provides some indications that strategic bias affects answers to price changes.  相似文献

In the United Kingdom the New Approach to Transport Appraisal (NATA) is used to appraise the economic, environmental and social impacts of transport projects. This analytical tool has recently been updated, but still fails to fully evaluate individual’s experiences of transport. It is important to understand more about passengers current journey quality for an informed judgement on the impact of future schemes. This paper presents findings of a methodological tool that can appraise Transport quality of life (TQoL) on all modes of transport in one city. Quality of life (QoL) techniques were applied to the transport networks of Glasgow and Manchester to determine if this is a valuable alternative in transport appraisal. Effective assessment confirmed the validity of the method highlighting in both locations that fixed modes, particularly Light Rapid Transport, are providing a significantly better quality of life compared to the bus.  相似文献

Spanish steelmaking policy in the 1970s and early 1980s was not especially different from that of the main European countries. The political transition was a tense experience that heightened the problems and made economic policy decisions harder to reach, but it did not cause a fundamental divergence from the rest of Europe. What made the steel restructuring policy fail and forced a new and costly restructuring in the 1990s, was the decision of the Socialist government, newly elected in 1982, to opt for maintaining the inland steelworks instead of the coastal steelworks. Its motives were related to the locations of these steelworks in socially and politically sensitive areas. The closure of Sagunto marked the end of the only real possibility of Spain having a competitive integrated steelworks in terms of its integration into Europe.  相似文献
