This study focuses on the dynamics of the gold price against bonds, stocks and exchange rates based on a disaggregation of the underlying relationships across different frequencies applying a wavelet decomposition. To analyze joint extreme movements (i.e. tail dependence), we adopt a copula approach, which helps us to assess the dependence between the returns of gold and other assets in calm and turmoil market times and therefore the hedge and safe haven functions of gold. We also examine whether gold prices are directly affected by changes in macroeconomic uncertainty, economic policy uncertainty and/or CPI forecasters disagreement. Analyzing data for nine economies for a sample period starting in 1985, we find that the role of gold changes significantly after the collapse of Lehman Brothers in 2008. Gold is unable to serve as a hedge or safe haven in the classical sense while the findings for the period prior to 2008 mostly suggest that gold is able to shield investors. Uncertainty measures display a surprising and time-varying relationship with the path of the gold price. While economic policy uncertainty is positively correlated with gold price changes, macroeconomic uncertainty and inflation uncertainty among forecasters are both negatively related to gold price changes. 相似文献
We explore how increased competition affects firms’ obfuscation strategies in a laboratory experiment. Firms sell a base good and an add‐on product. Besides choosing the base‐good price, sellers take an action that mimics the effects of shrouding the add‐on product. Shrouding is an equilibrium but an unshrouding equilibrium coexists. In our experiment, more competition matters, in that only duopolistic markets are frequently shrouded whereas four‐firm markets are not. With repeated interaction, shrouding rates do not increase. However, the opportunities to shroud facilitate tacit collusion on the base‐good price for the duopolies: the unshrouding equilibrium serves as a credible punishment if deviations occur. 相似文献
This article analyzes the relationship between gold quoted on the Shanghai Gold Exchange and Chinese sectorial stocks from 2009 to 2015. Using different copulas, our results show that there is weak but significant tail dependence between gold and Chinese sectorial stock returns. This means that the dependence between extreme movements of the two assets is not pronounced and confirms the role of gold as a safe haven asset. Based on analyzing the efficient frontier, CCC-GARCH optimal weights, hedge ratios and hedging effectiveness, we further show that adding gold into Chinese stock portfolios can help to reduce their risk. Gold appears to be the most efficient diversifier for stocks of the materials sector and the less efficient for the utilities sector. As a robustness check, we also compare gold to oil and indicate that gold is more efficient than oil in the diversification of Chinese stock portfolios.
Monetary budgets influence activity participation and related travel as they demarcate limits on how people organize their activities in time and space. In this paper, we are interested in money allocation to out-of-home leisure activities and how this is affected by duration, sociodemographics, and time-location variables. Analyses were carried out by applying a seemingly unrelated regression model to a leisure activity data set. The analyses revealed that expenditures for out-of-home leisure activities are influenced by the variables mentioned above. Moreover, the results indicate that there is a substitution between expenditure of each activity. 相似文献
This study applies stakeholder management principles to the port domain. We provide a conceptual framework for evaluating the communication strategies a (landlord) Port Authority (PA) relies on in the management of its relevant stakeholders and the adoption of disclosure to critical issues. The theoretical arguments are supported by empirical evidences from the Port of Rotterdam (PoR), i.e. a major port which leverages disclosure to successfully manage stakeholders and support the implementation of corporate strategy. The research questions are addressed using a content analysis on the annual reports (ARs) of PoR in the period 2000–2012. The overall research design enables the investigation of PA disclosure as a tool for managing the evolving interests of stakeholders from a longitudinal perspective. The PoR case shows that the relative importance of topics reported in the ARs change over time, as a result of external pressures and internal key events. The outcomes demonstrate the growing attention of PoR on topics relevant to the broader community (e.g. environment and safety/security) after a period characterised by a prominent focus on financial and governance issues. Besides, key breakthrough forces stimulating the shifts in landlord communication strategies are identified and discussed. Finally, by suggesting an indirect approach to evaluate how PA prioritises its salient stakeholders, the paper adds to extant port literature and brings methodological implications. 相似文献
Literature analyzes interorganizational relationships mostly from a relational perspective by emphasizing partnerships’ positive aspects. Yet business reality is often less romantic and more opportunistic. Especially within the automotive industry opportunistic behaviors often cause extreme reactions in both partners, resulting in poisoned relationships. This study examines the effects of bilateral opportunism between buyers and suppliers on both partners’ relationship induced financial performance, using an automotive industrial setting of new product development (NPD) partnerships. Furthermore, we evaluate the “opportunistic fit” between both partners to assess whether partnerships are characterized by opportunistic parity or unilateral domination. 相似文献
The introduction of the euro generated substantial interest in the impact of currency unions (CUs) on trade flows. Initial estimates suggested a tripling of trade, which gave rise to a literature in search of “more reasonable” CU effects. Theoretical derivations of the gravity model highlight, however that the CU literature neglects to control simultaneously for general equilibrium effects (multilateral resistance) and unobserved bilateral heterogeneity among trade partners. Once we introduce the appropriate controls, CU trade effects are shown to range around 50%. We also highlight that the practice of reporting average CU effects generates misleading results. The average effect is shown to be a composite of disparate individual CU effects ranging from 40% (euro) to about 100% (Central African franc). 相似文献
What are the costs and benefits of mandatory dividend rules? On the one hand, they make it harder for controlling shareholders to divert corporate assets. On the other hand, they reduce the internal funds available for firms to invest, possibly leading to the loss of valuable projects. To assess this trade-off, we look at investment and dividend decisions in a sample of public firms in Brazil. We show that a significant fraction of these firms use loopholes of Brazil's mandatory dividend rules to avoid paying dividends. And yet, the dividend rules are effective. They help explain why the average dividend yield in Brazil is higher than in the U.S., without making it harder for firms to invest. 相似文献
