This paper addresses two main questions. First, it seeks to establish whether the stylized facts of the ‘great moderation’ that have been documented for the UK and US economies can be found for the Euro area. Second, it explores possible explanations for any changes that have occurred in the volatility of Euro area output fluctuations. In examining why business cycles have moderated, much of the existing literature has tended to concentrate on a few key factors. These include shifts in the structure of the economy, improved monetary policy and a ‘good luck’ factor. This paper, however, follows a relatively new branch of the great moderation literature by focusing on whether international business cycle linkages have changed in a way that may have perpetuated the dampening in Euro area output fluctuations. The results show Euro area output fluctuations to have significantly reduced in variability over the last quarter of a century. The results go on to highlight that, although Euro area cycles differ little from rest of the world cycles, the moderation in Euro area output fluctuations is only marginally due to changes in international business cycle linkages and smaller international and domestic shock variances.  相似文献

The management and controlling of the industrial project acquisition process, with its staged, funnel-like structure, has been neglected in empirical research so far—even though an effective acquisition process is crucial for economic success. In addition to profitability, the main goal of industrial companies is to implement a pipeline process that ensures that the pipeline is always filled with acquisition projects and results in a constant stream of orders over time. The projects considered are characterized by complexity, uniqueness, and discontinuity. Based on a large-scale survey among German industrial companies, we describe the industrial project acquisition process, where the projects mentioned above are sold on a non-continuous basis to industrial customers. We assess how the industrial project acquisition process is really structured, whether a sales funnel management is applicable and utilized by sales management to monitor and control this process, and whether a sophisticated sales funnel management contributes to enhanced economic success.  相似文献

Although theory suggests that corporate hedging can increase shareholder value in the presence of capital market imperfections, empirical studies show overall mixed support for rationales of hedging with derivatives. Although various empirical challenges and limitations advise some caution with regard to the interpretation of the existing evidence, the results are consistent with derivatives use being just one part of a broader financial strategy that considers the type and level of financial risks, the availability of risk management tools, and the operating environment of the firm. Moreover, corporations rely heavily on pass‐through, operational hedging, and foreign currency debt to manage financial risk.  相似文献

This exploratory study extends the analysis of narrative disclosures from routine reporting contexts such as annual reports and press releases to non-routine takeover documents where the financial consequences of narrative disclosures can be substantial. Rhetoric and argument in the form of impression management techniques in narrative disclosures are examined. Prior thematic content analysis methods for analysing good and bad news disclosures are adapted to the attacking and defensive themes in the defence documents of target companies subject to hostile takeover bids. The paper examines the incidence, extent and implications of impression management in ten hostile takeover defence documents issued by target companies listed on the London Stock Exchange between 1 January 2006 and 30 June 2008. Three impression management strategies – thematic, visual and rhetorical manipulation – are investigated using content analysis methodologies. The findings of the research indicate that thematic, visual and rhetorical manipulation is evident in hostile takeover defence documents. Attacking and defensive sentences were found to comprise the majority of the defence documents analysed. Such sentences exhibited varying degrees of visual and rhetorical emphasis, which served to award greater or lesser degrees of prominence to the information conveyed by target company management.While exploratory in nature, this paper concludes with suggestions for future more systematic research allowing for greater generalisations from the findings.  相似文献

Information sharing between expatriate and host country national (HCN) employees is strategically significant. In a sample of Omani HCNs, we hypothesize and find that perceiving task cohesiveness is positively associated with HCNs’ willingness to share information with expatriates and that trust mediates this association. In addition, perceiving organizational support strengthens the relationship between expatriates’ task cohesiveness and HCNs’ trust, whereas interpersonal similarity has no influence. This research highlights important ways in which trust and information sharing may be encouraged, and that HCN–expatriate interpersonal similarity is less important to building trust when more diagnostic cues are available.  相似文献

This paper examines the effect of privatization on the priority of the maximum-revenue tariff and the optimum-welfare tariff in a mixed oligopoly with partial privatization and foreign competition. Major findings of this paper are that: firstly, in a mixed duopoly with partial privatization and asymmetric marginal costs, when the marginal cost of the privatized firm is higher than a critical value, the optimum-welfare tariff will be lower than the maximum-revenue tariff regardless of the order of firms?? move; secondly, if the degree of privatization is sufficiently high and cost is symmetric, the optimum-welfare tariff will be higher than the maximum-revenue tariff; thirdly, if the degree of privatization is sufficiently high and the domestic firm is highly ineffective in production, under Stackelberg public leadership, the optimum-welfare tariff is low and then it is more possible that the optimum-welfare tariff is lower than the maximum-revenue one.  相似文献

Many studies specify human mortality patterns parametrically, with a parameter change affecting mortality rates at different ages simultaneously. Motivated by the stylized fact that a mortality decline affects primarily younger people in the early phase of mortality transition but mainly older people in the later phase, we study how a mortality change at an arbitrary age affects optimal retirement age. Using the Volterra derivative for a functional, we show that mortality reductions at older ages delay retirement unambiguously, but that mortality reductions at younger ages may lead to earlier retirement due to a substantial increase in the individual?s expected lifetime human wealth.  相似文献

There are major differences between ex ante corporate investment plans and ex post investments. The case of China is useful for understanding this problem because there is substantial time series and cross sectional variation in the ratio of utilized to contracted FDI (UC ratio), which is less than one in most province-year observations. Provinces may believe that they are rewarded for reporting higher levels of contracted FDI, which would lead to lower UC ratios and higher policy incentives in subsequent years. Alternatively, provinces may be rewarded for reporting data more accurately, which would lead to higher UC ratios and policy incentives in subsequent years. Empirical analysis supports the second, institutional theory and suggests that provinces may increase their rate of utilizing pledged FDI by strengthening their legal systems and reducing government bureaucracy.  相似文献

This paper examines the links among casinos, hotels, and crime using Indiana's counties for 1994‐2004. In estimating casinos' impacts, I introduce a measure of casino activity in addition to variables related to the timing of casino opening. I test whether or not the number of hotel rooms affects crime rates. Increased casino activity reduces crime rates except for burglary, where crime rates rise after a lag. Leaving out a measure of casino activity appears to create a serious specification error. Finally, including problem crime data plagued by incomplete reporting affects the estimated impact of casinos on crime. (JEL R11, L83)  相似文献

Glück führte lange Zeit ein Schattendasein in der ?konomischen Forschung. Das hat sich seit einigen Jahren ge?ndert. Aus den neuen Erkenntnissen zu den wirtschaftlichen und au?erwirtschaftlichen Bestimmungsgründen des Glücks werden auch Empfehlungen für eine Wirtschaftspolitik abgeleitet, die das pers?nliche und gesellschaftliche Glück der Menschen berücksichtigt. Bruno S. Frey und Claudia Frey Marti fassen in diesem Beitrag ihr Buch1 zu dem Thema zusammen.  相似文献
