This paper attempts to examine how the inclusion of economic space affects trade policies and to make a comparison between optimal tariffs with endogenous location and those with exogenous location. In particular, it is shown that the output effect of a tariff change with endogenous location is greater than that with exogenous location if the production function is non-CRS. Moreover, when the production function is CRS (resp. not CRS), the optimal tariff under endogenous location is the same as (lower than) the one under exogenous location.  相似文献

This study examines the association between the selection of an industry‐specialist auditor and corporate social responsibility (CSR). We find that firms with higher CSR ratings are more likely to hire industry‐specialist auditors (national‐level industry leaders, city‐level industry leaders or joint city‐national industry leaders). Moreover, firms with better CSR performance related to product quality and the environment in controversial industries are found to select non‐specialized auditors. The results suggest that such firms may overinvest in CSR activities associated with the environment and product issues to disguise the sin nature of their manufactured goods, and simultaneously engage low quality auditors perhaps to avoid full disclosure of potential environmental and legal liabilities. Overall, we conclude that CSR is associated with the non‐controversial firms ensuring high quality financial reporting in response to societal expectations, and thus CSR firms in such industries have strong incentives to engage industry‐specialist auditors.  相似文献

Using a news-based index of economic policy uncertainty (EPU), we find that EPU is positively associated with credit default swap (CDS) spreads and negatively associated with the number of liquidity providers in the CDS market. A 10% increase in EPU leads to an 8.4% increase in CDS spreads and a 4.0% decrease in the number of liquidity providers. Furthermore, the effects of EPU are persistent and robust after controlling for macroeconomic variables. Our results are also robust to different econometric methodologies. Overall, our findings suggest that, when EPU is high, investors find credit protection more costly and difficult to purchase.  相似文献

This paper uses online users' reviews and sales information from May 2003 to March 2007 to study a new experiential product: online video game (or virtual world). The results suggest that, first of all, for a hedonic product such as an online video game, the availability of online review system could not fully transform experience attributes into search attributes. The empirical study confirms that negative word-of-mouth has more significant impact than positive reviews. The study empirically verifies that the existence of direct network externalities (i.e. a product's value increases when more consumers join the network) is crucial for a hedonic product. The size of the user base signals the quality of the game, and works like a search attribute for potential users. A large user base will reduce the negative impact from unfavorable reviews.  相似文献

While patient and public involvement (PPI) in health and social care research has progressed successfully in the last decade, a range of difficulties with the evidence base exist, including poor understanding of the concept of impact, limited theorization and an absence of quantitative impact measurement. In this paper, we argue that a paradigm change towards robust measurement of the impact of involvement in research is needed to complement qualitative explorations. We argue that service users should be collaboratively involved in the conceptualization, theorization and development of instruments to measure PPI impact. We consider the key advantages measurement would bring in strengthening the PPI evidence base through a greater understanding of what works, for whom, in what circumstances and why.  相似文献

The important role that consumers play in virtual communities as active participants in the value co-creation process has been increasingly acknowledged in recent marketing thought and practice. This study applies and extends the well-established value–attitude–behaviour (VAB) model to investigate how personal values and personality jointly influence consumers' attitude and behaviour towards their participation in virtual communities. The results show that while the resultant conservation value dimension has an indirect influence on consumer participation behaviour in virtual communities through attitude, the extraversion trait has a direct effect. The findings clarify our understanding of how personal values and personality differently predict consumer participation in virtual communities, and confirm the role of personal values and the VAB model in explaining this phenomenon. This study suggests significant implications for virtual community marketing.  相似文献

Despite the fact that many firms in a wide range of industries in various countries internationalize at or near inception, research on factors leading to the formation of born-globals has been limited to firms from advanced, open economies. In order to give a voice to the phenomenon of Vietnamese founding born-globals, we conducted an exploratory, multiple-case study. Three findings of this study are: (1) the major driver to the formation of Vietnamese born-globals is the entrepreneurs’ leadership desire together with the need for short-term profits; (2) their choice of internationalization mode is influenced by market conditions as well as the internationalization degree of the industries in which they find their business opportunities; and (3) the reason why other motivators found in earlier studies do not apply lies in the peculiarity of the Vietnam context.
