We analyze the relationship of retail investor sentiment and the German stock market by introducing four distinct investor pessimism indices (IPIs) based on selected aggregate Google search queries. We assess the predictive power of weekly changes in sentiment captured by the IPIs for contemporaneous and future DAX returns, volatility and trading volume. The indices are found to have individually varying, but overall remarkably high explanatory power. An increase in retail investor pessimism is accompanied by decreasing contemporaneous market returns and an increase in volatility and trading volume. Future returns tend to increase while future volatility and trading volume decrease. The outcome is in line with the conjecture of correction effects. Overall, the results are well in line with modern investor sentiment theory. 相似文献

The Luhmannian idea of functional differentiation offers a novel and radical systems-theoretic framework reinforcing the institutionalist vision of the embeddedness of the economic system in the societal and natural environment. Reflecting on Steffen Roth’s article, I formulate two complementary arguments. The first is that any self-organized complexity can be supported by the installation of a systemic boundary protecting it from the outer environment. The second is that this boundary prevents the complexity of the outer environment from being fully translatable into the intra-systemic complexity. Both arguments potentially inform the institutionalist analysis of the operational and moral problems of the economic function system. 相似文献

This paper proposes a method for pricing high-dimensional American options based on modern methods of multidimensional interpolation. The method allows using sparse grids and thus mitigates the curse of dimensionality. A framework of the pricing algorithm and the corresponding interpolation methods are discussed, and a theorem is demonstrated, which suggests that the pricing method is less vulnerable to the curse of dimensionality. The method is illustrated by an application to rainbow options and compared to least squares Monte Carlo and other benchmarks. 相似文献

This paper clarifies the nature of nonprofit accountability by distinguishing between the substantive and processual understandings of the public interest. The major theories of the nonprofit sector are shown to imply that this sector's activities correspond to the public interest only in its processual understanding, but not in the substantive one. Policy and management implications of this argument are discussed. 相似文献

Organizations face a common intertemporal choice problem, where actions suitable in the shortterm are different from those that work in the longterm. Building on the organizational ambidexterity theory, we argue that organizations can reconcile their short‐term and long‐term tensions, but this does necessitate managerial endeavours that orchestrate this reconciliation. We introduce the concept of temporal ambidexterity and define four intertemporal tensions involving an organization’s objectives, resources, markets, and uncertainty. We examine how firms can address these tensions successfully in the context of new ventures, and to do so we focus on three managerial capabilities of founder‐CEOs: expertise breadth, external connectivity, and empowering leadership. Results from 243 new ventures in China suggest that temporal ambidexterity improves with these managerial capabilities, and more so for younger ventures. Our findings shed light on solutions and mechanisms by which intertemporal balance is fulfilled, particularly for new ventures in a dynamic environment. 相似文献

International springboard is an entrepreneurial act that requires international entrepreneurial orientation (IEO). An important aspect of international springboard is the establishment of a deeply localized flagship foreign subsidiary to help pursue diverse international strategic goals. We model parent-level IEO as a mediator in the relationships between diversity of international strategic goals and flagship subsidiary localization strategies (customer responsiveness, market scope, and local cooperativeness). The results from a sample of 208 Chinese MNEs demonstrate that the three dimensions of IEO (innovativeness, proactiveness, and risk taking) play an important but differentiated mediation role. The study illustrates the connection between parent-level entrepreneurial behavior and subsidiary-level strategic actions through which MNEs capture cross-national entrepreneurial opportunities. 相似文献

The main thrust of the current nonprofit economics literature is that nonprofit organizations exist to correct market failures. However, the methodological individualism of the market failure theories of nonprofit organizations makes these theories unable to take account of the complex institutional embeddedness of the nonprofit sector. To fill this gap, the present paper outlines an approach of holistic nonprofit economics by building upon the insights from Thorstein Veblen’s institutionalism and Ervin Laszlo’s contribution to the general systems theory. From the Veblenian dichotomy, holistic nonprofit economics benefits by recognizing the limitations of the profit motive in ensuring a high quality of community life. From the systems theory conception of the multi-level universe, holistic nonprofit economics borrows the insight that the key to a high quality of community life is in the integration between man, society, and nature. Accordingly, holistic nonprofit economics locates the role of the nonprofit sector in ensuring this integration by counteracting the profit motive. Thus, in contrast to the market failure theories of nonprofit organizations, holistic nonprofit economics generates a research program exploring the embeddedness of the nonprofit sector into the encompassing societal and natural systems. 相似文献

The quality of strategic planning and resulting strategies is a key factor for the competitiveness of tourism destinations. Even though this is not a typical field where benchmarking methods are widely used, such an approach can be successfully applied. This article drafts a methodology for strategic benchmarking based on a quality evaluation of development strategies in tourism destinations. These strategies are evaluated by key regional stakeholders. The evaluation of fifteen selected strategies of the Czech, Slovak, and British regions has been made by an on-line application incorporating carefully defined criteria designed to operate with fuzzy data. The best strategies—as an etalon of good practice—are selected by the means of the fuzzy Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. The Region of Vysocina was selected for realization of the benchmarking gap analysis towards all strategies from the etalon with the aim to identify the opportunities for quality enhancement and corresponding good practices. 相似文献

This paper reconsiders the exchange paradigm of constitutional economics from the perspective of the theory of the division
of labor. According to this theory, human wants can be satisfied by two basic mechanisms—exchange and self-sufficiency. The
exchange paradigm of constitutional economics emphasizes the former mechanism while neglecting the latter. Building on major
economic theories of the third sector, it is argued that the latter mechanism is more helpful than the former in explaining
the existence of third sector organizations. The paper concludes by discussing implications of this argument for the further
development of constitutional economics.
