Organic agriculture, which produces commodities that can be qualitatively differentiated from conventional food products, has grown into an important market in many countries. The dynamics of commodity prices in both sectors are partly interdependent, but are also shaped by independent determinants and have rarely been studied. We analyze organic food markets and their interdependencies with conventional markets in the context of wheat markets in Germany, which have been subject to a number of fundamental changes during the last two decades. Based on institutional market characteristics, we suggest a flexible Markov‐switching asymmetric time series model. We find a pronounced temporal sequence of market phases that differ in their asymmetric dynamics and the extent to which the organic price is influenced by the conventional price. Organic wheat prices tend to be increasingly connected to prices of conventional wheat.  相似文献

Organizations increasingly depend on employee efforts to innovate. However, the quality of relationships between leaders and employees may affect the recognition that employees receive for their innovative work behaviors. Drawing from a social cognition perspective, we tested a model in which leader–member exchange (LMX) moderates the impact of employee innovative work behavior on supervisory ratings of employee performance. Results from two multisource studies combining self, colleague, and supervisor ratings consistently showed that employees receive more favorable performance ratings by engaging in innovative work behavior when they have high‐quality LMX relationships. Moreover, we found that this interactive relationship was mediated by leader perceptions of innovative employee efforts, providing support for a moderated mediation model. Implications for the literatures on performance appraisal, LMX, and innovation are discussed.  相似文献

Abstract

Despite the strong evidence for the beneficial influence of resilience for employee stress resistance in domestic settings, the construct has not received much attention in the expatriation literature, where stress is considered a major factor for expatriates’ poor cross-cultural adjustment and turnover. Drawing upon conservation of resources theory, the present study examines resilience as an antecedent of expatriate work adjustment and turnover intentions. Furthermore, this study investigates the moderating role of perceived organizational inclusion climate as a resource-protecting organizational factor. Results from a survey of 175 expatriates in South Korea indicate that resilience is positively related to expatriate work adjustment and that these positive effects are more pronounced when expatriates perceive their organizational climate to be highly inclusive. Furthermore, findings suggest that work adjustment mediates the effects of resilience on turnover intentions and that this mediation is moderated by a perceived organizational inclusion climate. Implications for theory and practice are discussed.  相似文献

This article focuses on the risks of nanomaterials and nanotechnologies, and the challenges they pose to European consumer law. These risks are exemplary for the sociological phenomenon of modern risk society, living under the condition of uncertainty with regard to the likelihood and the extent of possible negative effects. Generally, in law important functions in risk societies are fulfilled by the precautionary principle. It serves both, as a justification for state measures vis-à-vis other legal interests, especially economic human rights, and as a request for state action in response to possible risks. This paper will argue that the precautionary principle applies at least to health protection as a core part of consumer protection and basically EU law is well equipped to deal with uncertainties. This is established in case law and practice. However, although there is pressure to apply the precautionary principle to nanomaterials and nanotechnologies, the European Commission has adopted a rather modest approach. That has been criticized especially by the European Parliament. For dealing with the gap in basic research and methodology, this article suggests a burden sharing in financing taking into account both, the precautionary principle and the principle of proportionality.  相似文献

We study the relationship of corporate social responsibility (CSR) and the distribution of stock returns for an international sample. Firms with a high level of CSR generally exhibit superior stock price synchronicity in the markets of Europe, Japan, and the United States. In particular, we identify optimal levels of CSR to minimize idiosyncratic risk for each region. Moreover, CSR has a mitigating effect on crash risk in Europe and the United States. In contrast, firms from the Asia‐Pacific region display CSR over‐investment followed by a higher crash risk. This appears to be a consequence of globalization, which forces firms from Asia‐Pacific to overinvest in CSR to adapt western standards.  相似文献

In recent years, participation in flamenco, as a cultural art form, has gained momentum within Spain and internationally. Engagement in flamenco music and dance workshops in Spain has also become an increasingly significant tourism activity. Despite this trend, little research has looked into the nature of leisure experiences of flamenco. This paper seeks to address this knowledge gap by exploring how tourists experience flamenco music and dance courses in the city of Seville. Through a grounded theory research strategy in which in-depth interviews were conducted with 20 participants, the study reveals that four key themes characterise tourists’ experiences of flamenco. These are: the social and physical environment, which refers to physical flamenco spaces in Seville and tourists’ interactions with instructors and peers; secondly, the experience of challenge, characterised by hardship and sacrifice in the pursuit of flamenco; thirdly, activation of the sensual body or a sense of arousal; and lastly, an intrinsic and deep desire for self-discovery. The study demonstrates that the flamenco tourist experience strongly contributes to self-realisation and fulfilment of those who engage in it, or in other words, that the flamenco tourist experience is eudaimonic in character. The interview findings were linked to literature on self-realisation, self-fulfilment, true self, stress-related growth and related eudaimonic themes. Eudaimonia, or a sense of personal expressiveness and self-realisation, has not been previously established in this context. Therefore, the research findings provide a theoretical understanding of what a eudaimonic tourist experience of dance and music may look like.  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

Flexible exchange rates as shock absorbers   总被引:1,自引:0,他引:1  
In this paper we analyze empirically the effect of terms of trade shocks on economic performance under alternative exchange rate regimes. We are particularly interested in investigating whether terms of trade disturbances have a smaller effect on growth in countries with a flexible exchange rate arrangement. We also analyze whether negative and positive terms of trade shocks have asymmetric effects on growth, and whether the magnitude of these asymmetries depends on the exchange rate regime. We find evidence suggesting that terms of trade shocks get amplified in countries that have more rigid exchange rate regimes. We also find evidence of an asymmetric response to terms of trade shocks: the output response is larger for negative than for positive shocks. Finally, we find evidence supporting the view that, after controlling for other factors, countries with more flexible exchange rate regimes grow faster than countries with fixed exchange rates.  相似文献

In this paper, we study the implied volatility smirk (IVS) of options written on the FXI, the Financial Times Stock Exchange/Xinhua China 50 Index exchange-traded fund (ETF). Using the methodology of Zhang and Xiang (2008, Quant Financ, 8, pp. 263–284), we document the empirical characteristics of the level, slope, and curvature of IVS of the FXI options. We find that, on average, IVS becomes steeper and more convex as time to maturity increases. The level and curvature are usually positive, and the slope is negative. We provide evidence that the information in the quantified IV factors has some predictive power for the future monthly FXI ETF returns.  相似文献
