中国农村人口贫困变动研究——基于多维脱贫指数测度

本文通过多维贫困识别方法构建相应指数，提出了在返贫和脱贫不同方向上对多维贫困的变动进行分解的思路。同时，用2010—2014年中国家庭追踪调查数据对中国农村人口多维贫困的变动进行了分解，得出以下结论：第一，收入依然是农村人口多维贫困的主要维度，但在改善收入贫困的同时应该防范健康维度返贫的风险。第二，农村人口的多维贫困状况在不断改善，但是由于返贫的影响，脱贫的效果受到了较大削弱，因此在注重脱贫的同时，不应忽视返贫的风险。第三，持续贫困人口贫困状况虽然后来有所改善，但是2012年的恶化状况提示我们对于暂时未能脱贫的人口，还需要采取措施缓解其贫困状况。     

E-marketing services and e-marketing performance: the roles of innovation,knowledge complexity and environmental turbulence in influencing the relationship

The business-to-business electronic marketplace (e-marketplace) is becoming critical for small- and medium-sized enterprises (SMEs). However, which e-marketing services determine a firm’s e-marketing performance and how innovation, knowledge complexity and environmental turbulence influence the relationship between e-marketing services and e-marketing performance are under-researched topics in the field. We first empirically tested 176 SMEs from China to evaluate which e-marketing services are significantly related to e-marketing performance and how these services collectively influence the performance. Then, we used an NK model to examine how innovation, knowledge complexity and environmental turbulence mediate/moderate the relationship. The results show that five e-marketing services (e-CRM, e-SCM, e-competitiveness, IS/IT integration and information transparency) can greatly influence e-marketing performance; innovation positively mediates the relationship between e-marketing services and performance; and knowledge complexity and environmental turbulence positively moderate the relationship.

Instrumental variable estimation of a nonlinear Taylor rule

This article studies nonlinear, threshold, models in which some of the regressors can be endogenous. An estimation strategy based on instrumental variables was originally developed for dynamic panel models and we extend it to time series models. We apply this methodology to a forward-looking Taylor rule, where nonlinearity is introduced via inflation thresholds.     

An evolutionary explanation of the value premium puzzle

As early as 1934 Graham and Dodd conjectured that excess returns from value investment originate from a tendency of stock prices to converge towards a fundamental value. This paper confirms their insights within the evolutionary finance model of Evstigneev et al. (Econ Theory 27:449–468, (Evstigneev et al. 2006)). Our empirical results show the predictive power of the evolutionary benchmark valuation for the relative market capitalization and its dynamics in the sample of firms listed in the Dow Jones Industrial Average index in 1981–2009.

Rahmenbedingungen, Charakteristika und Konsequenzen freiwilliger Unternehmenspublizit?t – State of the Art und neue Perspektiven der empirischen Forschung

Die freiwillige Unternehmenspublizit?t dient vor allem der Information der Investoren zum Abbau von Informationsasymmetrien und einer Minderung von Prinzipal-Agent-Konflikten. Vor diesem Hintergrund analysiert der vorliegende Beitrag Befunde zu den mit einer Ver?ffentlichung einhergehenden Kapitalmarktkonsequenzen. Dabei werden gezielt bisherige Erkenntnisse für den deutschen Kapitalmarkt berücksichtigt. Zur Systematisierung der Ergebnisse werden die Studien anhand eines aus drei Komponenten (Rahmenbedingungen, Charakteristika und Konsequenzen) bestehenden konzeptionellen Bezugsrahmens geordnet. Es zeigt sich, dass internationale Studien meist zwei oder sogar drei Komponenten der freiwilligen Publizit?t gleichzeitig berücksichtigen und so umfassendere Aussagen treffen k?nnen, w?hrend für den deutschen Kontext Nachholbedarf zu konstatieren ist. Darüber hinaus werden weitere Forschungsfelder aufgezeigt, die bis dato auch international wenig Beachtung gefunden haben, obgleich sie zunehmend an Relevanz gewinnen.

Decision-making in sequential projects: expected time-to-build and probability of failure

The main purpose of this paper is to account for the two most basic options in the context of a sequential investment project, the option to adjust investment speed and the exit option. Current models of sequential investment ignore the role of a minimal investment rate that must be sustained as long as the project is not abandoned. In most real projects, a positive minimal investment rate provides an incentive for (irreversible) exit from the project. On the other hand, the minimal investment rate still leaves room for adjustment of the investment speed. Therefore, models with realistic (non-extreme) assumptions about the minimal investment should account for both, the exit option and the option to adjust investment speed. In this paper we set up the equations for this dual-option scenario in a continuous (PDE) framework. The resulting model is characterized by the presence of two thresholds describing the optimal decision-making. We provide a robust numerical procedure for the determination of both thresholds. Our analysis reveals that the minimal investment rate creates an endogenous incentive for fast completion that complements the corresponding exogenous incentives. This ??incentive-enhancement effect?? of the minimal investment rate is reflected by the fundamental statistical characteristics of the sequential project. As a direct consequence of this effect, an increase of the minimal investment rate will always lead to a reduction of the expected time-to-build. Another, striking consequence is that the minimal investment rate can also have a positive effect on the probability of failure (default-risk). This effect occurs under the condition of a low exogenous incentive for fast completion, represented e.g. by poor market expectations for the product to be developed.
