The article examines the state of power supply in Ukraine for the period from 2000 to 2010. The trend in the Ukraine GDP energy intensity (at purchasing power parity), compared to other countries of the Commonwealth of Independent States, is analyzed. The key points of demand determination and of alternative ways to satisfy it in Ukraine for the period until 2015 are formulated. A forecast of production and consumption of energy resources was conducted in accordance with the expected socioeconomic development of the country through the development of advanced fuel and energy balances.  相似文献

Carbon offsets allow consumers to mitigate their guilt associated with their carbon footprint. On the one hand, when offsets are purchased in an industry unrelated to the consumption activity, offsets are complements to consumption and the introduction of an offset market causes consumption to rise. On the other hand, when offsets are purchased in a related industry, consumption and offsets are substitutes and consumption falls. In general, however, net emissions decline. We find two exceptions to this rule. First, when offsets are purchased in an unrelated market, if there is no latent demand for offsets in their absence, the introduction of offsets can potentially cause a rise in net emissions when producers of “dirty” consumption goods have market power. Second, when offsets are purchased to fund green energy, emissions can rise if “dirty” producers can engage in pre‐emptive strategic commitments and the price of offsets is chosen endogenously.  相似文献

We investigate welfare and aggregate implications of a pay-as-you-go (PAYG) social security system in a dynastic framework in which individuals have self-control problems. The presence of self-control problems induces individuals to save less because of their urge for temptation towards current consumption. Individuals' efforts to balance between the short-term urge for temptation and the long-term commitment for consumption smoothing result in self-control costs. In this environment PAYG social security works as a self-control cost reducing device. In contrast, the presence of altruism induces individuals to save more. This in turn mitigates the adverse effects of self-control problems and PAYG social security on savings but magnifies the self-control costs. We find that in our environment the adverse welfare effects of a PAYG system are further mitigated relative to the environments that incorporate altruism and self control issues separately. However, the level of mitigation is quite modest.  相似文献

Whereas empirical evidence on the effect of higher commodity prices on the long-run growth of commodity exporters is ambiguous, time series analyses using vector autoregressive (VAR) models have found that commodity booms raise income in the short run. In this paper we adopt panel error correction methodology to analyze global data for 1963 to 2008 to disentangle the short and long run effects of international commodity prices on output per capita. Our results show that commodity booms have unconditional positive short-term effects on output, but non-agricultural booms in countries with poor governance have adverse long-term effects which dominate the short-run gains. Our findings have important implications for non-agricultural commodity exporters with poor governance, especially in light of the recent wave of resource discoveries in low-income countries.  相似文献

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
