Particularly in the field of German research tradition concerning financial accounting thoughts about interpretation and development of standards are focal points. Along with the appearance of the information economics it became apparent that financial accounting is not only a technical vehicle but a social institution. By making accounting information publicly available it may have an effect on the distribution of economic income. Insofar the presumption is feasible that those players influence standard-setting whose welfare is directly affected by it. The above mentioned view that is rarely noted in the German-speaking countries is followed by the research approach so called ‘‘Political Economy of Accounting’’. Aim of this research approach is to explain the complex standard-setting process by considering the different parties within a society. The article at hand contributes to sum up state-of-the-art advancements in the field of scientific discourse concerned and provides an outlook on perspectives in this research area. 相似文献

Political targets for implementing the German “energy turnaround” aiming at the ambitious extension of renewable energies to generate electricity. However, a majority of the renewable supply is provided by intermittent sources, e.g. wind and solar power. For balancing the increasing supply fluctuations additional storage options are claimed beside of an enforced grid infrastructure and a more flexible demand side. Despite of the political guidelines the economics of additional flexibility measures has to be considered. For this paper we analyse the costs of large scale stationary battery storages to be operated in wholesale markets and transmission grid level. By deriving a key figure based on a life-cycle cost approach, we are able to evaluate the additional costs of electricity of selected battery technologies (lead-acid, lithium ion, sodium sulphur, redox-flow). Moreover, current and valid parameters of the cost analysis are received by scientific and industrial stakeholders of battery systems via online survey and face-to-face interviews. According to the stakeholder estimation a nationwide operation of stationary battery storages will be established at wholesale and transmission grid level until the year 2030. The life-cycle cost analysis, which also includes estimated future cost reductions, shows that lead-acid batteries remain the cost-efficient technology, assuming about 100 storage cycles p.a. In addition, a sensitivity analysis reveals the impact of increasing annual storage cycles as well as the achievable cost reduction by economies-of-scales of the power unit of the storage system. 相似文献

In this work, we are concerned with valuing the option to invest in a project when the project value and the investment cost are both mean-reverting. Previous works on stochastic project and investment cost concentrate on geometric Brownian motions (GBMs) for driving the factors. However, when the project involved is linked to commodities, mean-reverting assumptions are more meaningful. Here, we introduce a model and prove that the optimal exercise strategy is not a function of the ratio of the project value to the investment V/I – contrary to the GBM case. We also demonstrate that the limiting trigger curve as maturity approaches traces out a nonlinear curve in (V, I) space and derive its explicit form. Finally, we numerically investigate the finite-horizon problem, using the Fourier space time-stepping algorithm of Jaimungal and Surkov [2009. Lev´y based cross-commodity models and derivative valuation. SIAM Journal of Financial Mathematics, to appear. http://www.ssrn.com/abstract=972837]. Numerically, the optimal exercise policies are found to be approximately linear in V/I; however, contrary to the GBM case they are not described by a curve of the form V*/I*=c(t). The option price behavior as well as the trigger curve behavior nicely generalize earlier one-factor model results. 相似文献

The German energy transition represents a policy-driven, sustainability-oriented restructuring of both supply- and demand-side components of the entire energy system by 2050. Whereas the development of renewable energies in the electricity sector is right on track, due to the feed-in tariffs of the German Renewable Energy Sources Act, many other crucial requirements for a successful transition are not, amongst others the improvement of energy effi ciency and the decarbonisation of the transport sector. Contrary to the public discussion, the primary future challenges do not consist in limiting electricity prices or abandoning feed-in support schemes, but rather in coordinating the variety of actors as well as appropriately matching the different system elements (grids, technologies, energy sectors, demand and supply side, etc.). Much remains to be done. By highlighting some examples like the need to take into account future implications of climate change for the energy sector, the consequences of the current crisis in the European Union’s emissions trading scheme and the need for a cautious adjustment of the EEG, the paper argues that the major challenges regarding the German energy transition mainly go beyond the current policy-driven and short-term discussion of energy prices. Germany’s pioneering attempt to integrate steadily increasing share of non-dispatchable electricity from renewable sources is challenging the stability of the system. Several characteristics in the current selfregulating system are identifi ed and analysed, which reveal themselves as potential weaknesses or shortcomings in the upcoming system. 相似文献

Using a novel approach, this paper analyses the deliberately communicated uncertainty of the ECB to the market. Specifi cally, it semantically analyses the uncertainty expressed in offi cial ECB press statements. The analysis shows how the ECB tries to alert or appease the market with different levels of communicated uncertainty. The appeasement through low uncertainty communication levels is particularly pronounced during times of fi nancial distress. Further, the analysis shows that the ECB tried to alert the market through an increasing level of communicated uncertainty prior to the outbreak of the global fi nancial crisis. 相似文献

In this article the conditions for the rise and fall of representative regimes are explored. High citizen mobility and unexploited
opportunities for investment create the need of reassuring factor owners against the tax hunger of the State. This may lead
to the emergence of representative institutions of government, a process that reverts when those conditions disappear. Factors
that facilitate or restrain the mobility of citizenry are identified, mainly in the domain of military technology. Thus, a
number of interrelations between production and war technologies, political development and economic performance are revealed,
giving rise to an interpretation of historical evolution.

This paper contributes to the scarce body of research on employee turnover in multinational corporations' foreign subsidiaries and addresses some key issues related to dealing with turnover of local staff. Based on a literature review, I conceptualize locals' perceived career prospects and their organizational identification as key variables mediating the relationship between international staffing practices and local staff turnover. In a second step, the paper develops instruments that help international firms to retain their subsidiary staff. Specifically, I focus on how international staffing practices need to be configured to ensure employee retention and I derive moderating factors. My arguments are integrated into a framework for the effect of international staffing practices on subsidiary staff retention in multinational corporations. 相似文献

Recent operations management and innovation management research emphasizes the importance of supplier integration. However, the empirical results as to the relationship between supplier integration and time-to-market are ambivalent. To understand this important relationship, we incorporate two major recent developments. First, the literature has started to redefine supplier integration into two dimensions, supplier product integration and supplier process integration. Second, recent research has begun to examine spillover effects that extend beyond the direct costs and benefits of the supplier contract. Using survey data of 116 firms in the industrials, health care, and information technology industries, the results confirm our hypotheses and show that supplier product integration decelerates time-to-market while supplier process integration accelerates time-to-market. The results also show a positive relationship between supplier integration and the adoption of external technologies, which either decelerates or accelerates time-to-market depending on the level of internal exploration activities. Our research, thus, helps to open the ‘black-box’ of the relationship between supplier integration and time-to-market, and provides a theoretically grounded explanation to the apparent contradictory results in prior research about the influence of supplier integration on time-to-market. In addition, we contribute to research on spillover effects by emphasizing that information technology adoption and assimilation is an important spillover effect of supplier integration. 相似文献

Zusammenfassung Wie kann man zuverl?ssige Methoden entwickeln, um die Erfolgswirkungen von Marketingma?nahmen auf den Unternehmenswert zu
messen? Am Anfang steht dabei die Frage, was Marketingerfolg eigentlich ist. Eine reine Fokussierung auf die Stakeholdergruppe
der Kunden reicht hier nicht aus. Andere, durch Marketing ebenfalls erreichte Interessensgruppen wie z.B. Investoren oder
Mitarbeiter müssen auch betrachtet werden. Und das alles vor dem Hintergrund moderierender Kontextfaktoren wie etwa der Unternehmensstrategie
oder der Branche.

We experimentally test the predictive success of three stationary concepts in two cyclic duopoly games. The concepts are Nash equilibrium, impulse-balance equilibrium and payoff-sampling equilibrium. In the experiment 11 independent subject groups, consisting out of six participants interacting over 200 rounds, were gathered for each game. The comparison of the three concepts with mixed strategies shows that the order of performance from best to worst is as follows: payoff-sampling equilibrium, impulse-balance equilibrium, and Nash equilibrium. In addition the data exhibit a weak but significant tendency over time in the direction of coordination at a pure strategy equilibrium. 相似文献
