论相遇与冲突下的动态文化

文化是动态的,文化的发展主要有三种形式:文化创新、文化传播和文化涵化。不同文化相遇后会发生冲突与矛盾,并给自身的发展带来新的挑战和机遇。在21世纪全球化背景下,跨文化交际日益频繁,如何理解与处理这些矛盾与挑战,促进文化交流,同时又保持各自文化的独特性,更变得愈发重要。

The effects of influence strategies on dealer satisfaction and performance in Taiwan's motor industry

The studies of influence strategies in channel relationships have focused on western, individualistic countries. This study seeks to extend the empirical findings in Taiwan's motor industry to elucidate differences among diverse context. The results reveal that the promise strategy must be separated from coercive strategies and the request strategy must be separated from noncoercive strategies under the context of Taiwan's motor industry. Moreover, discrimination between economic and social satisfaction helps relationships between influence strategies and satisfaction and the effects of satisfaction on performance to be understood. The dealer's satisfaction is positively related to his performance, and social satisfaction is more important than economic satisfaction.     

Marketing of competence: Exploring the resource-based content of value-for-customers through a case study analysis

In this article, we propose a competence-based view of value-for-customer in business markets. While literature in both strategy and marketing has provided many insights to understand the competence-based roots of value creation, the interface between the two areas is still largely unexplored. Moreover, while the notions of competence exchange and value creation feature strongly in the relational perspective, they occur only once relationships have been established. This begs the question whether competencies could be developed outside established relationships, and then marketed to guide customers' buying behavior. Basing on three case studies from the yarn manufacturing, IT systems, and automotive components industries, we identify key features of competence-based marketing: the alignment of supplier's competencies with the customer's business processes, the experiential communication of supplier's competencies, and the delivery of competencies to the buyer's business processes. Within the strategies for creating value-for-customers, these findings contribute to the understanding of the use of competencies to induce purchases.

Communicating risk for issues that involve ‘uncertainty bias’: what can the Israeli case of water fluoridation teach us?

Water fluoridation is a controversial issue in public health. Despite the uncertainty regarding its efficacy and safety, health officials continue to communicate it as ‘unequivocally’ safe and effective. Our focus is on how health officials and policy-makers in Israel frame the issue of water fluoridation in terms of certainty while promoting a mandatory fluoridation policy. According to van Asselt and Vos, the uncertainty paradox describes situations in which uncertainty is acknowledged, but the role of science is framed as providing certainty. Our study is an analysis of documents and media articles emphasizing the paradoxical language used by official representatives on the controversial topic of fluoridation. A central contribution of this study is that we coin the term ‘uncertainty bias,’ in which policy-makers do exactly what they accuse laypeople of doing, framing uncertainty in biased terms. We found that in order to establish mandatory regulation, health ministry officials expressed information in an unbalanced format, promoting the topic of fluoridation by framing it in exclusively positive terms. This study does not focus on the practice of water fluoridation per se, and is not intended to decide for or against it, but rather, to explore how the debate regarding it is communicated. Understanding this particular case can shed light on how other controversial topics are transformed into health policy that is characterized in equivocal terms.     

A framework for the analysis of firm risk communication

In this paper, we propose a framework for the analysis of risk communication and an index to measure the quality of risk disclosure. Mainstream literature on voluntary disclosure has emphasized that quantity can be used as a sound proxy for quality. We contend that, in the analysis of the disclosure of risks made by public companies, attention has to be paid not only to how much is disclosed but also to what is disclosed and how.We apply the framework to a sample of nonfinancial companies listed in the ordinary market on the Italian Stock Exchange. To verify that the framework and synthetic index are not influenced by the two factors recognized in the literature as the most powerful drivers of disclosure behavior for listed companies, we use an OLS model. The regression shows that the index of disclosure quantity is not influenced either by size or industry. Thus, the synthetic measure can be used to rank the quality of the disclosure of risks.     

The Disciplining Role of Accounting in the Long-Run

One role of accounting is to discipline softer (more manipulable) sources of information. We use a principal-agent model of hidden actions and hidden information to study this role. In our model, there is both a verifiable signal (a publicly observed output) and an unverifiable signal (a productivity parameter privately observed by the agent). In a one-period setting, the optimal contract does not make use of the agents report on the private signal. However, when the output is tracked over two periods, the agents communication can be valuable. This reversal of results suggests uncovering the disciplining role of accounting may require a long-term perspective.JEL Classification: D82, M41     

Model-driven statistical arbitrage on LETF option markets

In this paper, we study the statistical properties of the moneyness scaling transformation, which adjusts the moneyness coordinate of the implied volatility smile in an attempt to remove the discrepancy between the IV smiles for levered and unlevered ETF options. We construct bootstrap uniform confidence bands which indicate that the implied volatility smiles are statistically different after moneyness scaling has been performed. An empirical application shows that there are trading opportunities possible on the LETF market. A statistical arbitrage type strategy based on a dynamic semiparametric factor model is presented. This strategy presents a statistical decision algorithm which generates trade recommendations based on comparison of model and observed LETF implied volatility surface. It is shown to generate positive returns with a high probability. Extensive econometric analysis of the LETF implied volatility process is performed including out-of-sample forecasting based on a semiparametric factor model and a uniform confidence bands' study. These provide new insights into the latent dynamics of the implied volatility surface. We also incorporate Heston stochastic volatility into the moneyness scaling method for better tractability of the model.
