The German Corporate Tax Reform Act of 2008 requires an adjustment of classic valuation concepts because it limits interest deduction from taxable income depending on the operating performance of the company. By using time- and state-contingent discount rates in a risk-neutral valuation with predetermined debt levels, a theoretically sound valuation result is obtained. However, a modified APV-concept which assumes deterministic debt over the planning horizon and constant leverage in the terminal value phase also yields consistent valuation results when two types of tax shields with different levels of risk are distinguished. 相似文献

The class of affine LIBOR models is appealing since it satisfies three central requirements of interest rate modeling. It is arbitrage-free, interest rates are nonnegative, and caplet and swaption prices can be calculated analytically. In order to guarantee nonnegative interest rates affine LIBOR models are driven by nonnegative affine processes, a restriction that makes it hard to produce volatility smiles. We modify the affine LIBOR models in such a way that real-valued affine processes can be used without destroying the nonnegativity of interest rates. Numerical examples show that in this class of models, pronounced volatility smiles are possible. 相似文献

Many hypothesis tests are univariate tests and cannot cope with multiple hypothesis without an auxiliary procedure as e. g. the Bonferroni-Holm-procedure. At the same time, there is an urgent need for testing multiple hypothesis due to the very simple existing methods as the Bonferroni-correction or the Bonferroni-Holm-procedure, which suffers from a very small local significance level to detect statistical inferences or the drawback that logical and statistical dependencies among the test statistics are not used, whereby its detection is NP-hard. In honour of this occasion, we present a multiple hypothesis test for i.i.d. random variables based on conditional differences in means, which is capable to cope with multiple hypothesis and does not suffer on such drawbacks as the Bonferroni-correction or the Bonferroni-Holm-procedure. Thereby, the computation time can be neglected. 相似文献

L'effet des obstacles aux échanges sur l'emploi généré par les chaînes d'approvisionnement mondiales
Les auteurs étudient l'effet des obstacles aux échanges internationaux de biens et de services sur les marchés du travail des pays producteurs en partant des estimations du BIT sur l'emploi imputable aux chaînes d'approvisionnement mondiales. L'analyse empirique confirme largement les prédictions d'un modèle théorique calibré avec des données de la base WIOD (2000 et 2011). Les obstacles au commerce de produits manufacturés ou de services ont un effet transfrontalier, intrasectoriel et intersectoriel, sur l'emploi, qui reflète l'interdépendance croissante entre pays et secteurs. L'effet intersectoriel s'affirme avec le temps. Les politiques commerciales semblent donc pouvoir avoir des effets externes importants sur les marchés du travail étrangers. 相似文献

This study reviews literature on paradoxical tensions between value co‐creation and capture in interorganizational relationships (IORs). The purpose of this review is to make a re‐evaluation of the literature by engaging a paradox theory lens, thereby identifying factors that render tensions salient and factors that lead to virtuous or vicious cycles. This review of 143 articles reveals factors that make tensions salient: these relate to plurality (e.g. coopetition), scarcity (e.g. lack of experience with IORs), change (e.g. changes in collaboration scope) or combinations thereof (e.g. IORs in weak appropriability regimes). Results also uncover factors that resolve paradoxical tensions of value co‐creation and capture, thus spurring virtuous cycles (e.g. carefully mixing trust and contracts), as well as factors that promote vicious cycles, owing to the emphasis on either value co‐creation or capture (e.g. myopia of learning). This review further reveals a new category of factors that may stimulate either virtuous or vicious cycles, depending on the extent to which they are enforced. This finding expands the value co‐creation–capture paradox resolution and brings to light new dynamics in the paradox framework of dynamic equilibrium. This study thus contributes by: (1) reassessing the existing literature and applying paradox theory to the well‐known hazard of value co‐creation and capture; (2) highlighting factors that amplify paradoxical tensions related to this hazard; and (3) outlining factors that help solve the paradox by embracing its contradictory poles and factors that hinder paradox resolution by emphasizing either value co‐creation or appropriation. 相似文献

Population forecasts entail a significant amount of uncertainty, especially for long-range horizons and for places with small
or rapidly changing populations. This uncertainty can be dealt with by presenting a range of projections or by developing
statistical prediction intervals. The latter can be based on models that incorporate the stochastic nature of the forecasting
process, on empirical analyses of past forecast errors, or on a combination of the two. In this article, we develop and test
prediction intervals based on empirical analyses of past forecast errors for counties in the United States. Using decennial
census data from 1900 to 2000, we apply trend extrapolation techniques to develop a set of county population forecasts; calculate
forecast errors by comparing forecasts to subsequent census counts; and use the distribution of errors to construct empirical
prediction intervals. We find that empirically-based prediction intervals provide reasonably accurate predictions of the precision
of population forecasts, but provide little guidance regarding their tendency to be too high or too low. We believe the construction
of empirically-based prediction intervals will help users of small-area population forecasts measure and evaluate the uncertainty
inherent in population forecasts and plan more effectively for the future. 相似文献

Intercultural coaching takes place in the highly complex reality of a globalized world. The coachee is an individual acting in the situational context of his assignment and his corporate culture. He has been socialized in his own culture, but is communicating and interacting with people who have been socialized in different cultures. In order to identify and solve problems, all three aspects (person, situation, culture) have to be considered. Some aspects may have more influence than others may, but they combine in a closely interwoven system. The authors outline the theoretical background of intercultural coaching and illustrate the process with case studies. 相似文献

By applying the concept of participatory spaces, this article maps and analyzes current research on mental health service user organizations (MHSUOs). We have analyzed research literature from 2006 to 2016 to examine how the role of and challenges facing MHSUOs are formulated in the post-deinstitutional era. The current situation is marked by MHSUOs parallel presence in invited, claimed and popular spaces for participation. The post-deinstitutional era is characterized by a shift in focus from gaining access to such participatory spaces, to critically examining the political opportunities available in these. We further argue that the dominance of psychiatry-specific spaces could prevent MHSUOs from fully exploring their potential for participation in broader social issues. 相似文献

Occupational health management and science increasingly focus on the issue of health-promoting leadership. Meanwhile a lot of leadership behaviors have been identified that affect the health of employees. To measure them requires high costs. Therefore, the aim of this study is to identify core-factors of salutogenic leadership and to operationalize them for an efficient diagnosis. As an integrative work-related indicator of employees’ health sense of work coherence (Work-SoC) was chosen. In a deductive and inductive process the TIMP-inventory has been developed that enables the economic assessment of three leadership dimensions: Trust, Incident Management and Pressure. These factors explain with less items more variance of the Work-SoC construct than established general and health-related leadership scales of transformational leadership, consideration, social support, demanding leadership as well as positive and negative health behavior. That is why the TIMP-factors can be recognized as core-factors of health-promoting leadership. 相似文献
