明清时期长江中游地区地方文献记载的茭簰,并非漂浮种植性质的葑田,而是漂浮居住性质的水上居家设施。“随波上下”且“不时迁移”是其基本特性,实质是借水之力以避水之害,乃湖区居民应对洪涝灾害的居住创举。茭簰不同于为众熟知的舟船,亦有别于水上航行的排筏,茭簰居民并非渔民,而是备有“种莳牲畜”的农民。茭簰与葑田,虽然一耕一居,却具有共同的指向。茭簰是湖区农家适应环境变化,根据生产生活需要而做出的相对选择,堪称湖区居民趋利避害、协调人水关系的代表性举措。 相似文献

This paper investigates the predictability of foreign exchange (FX) volatility and liquidity risk factors on returns to the carry trade, an investment strategy that borrows in currencies with low interest rates and invests in currencies with high interest rates. Previous studies have suggested that this predictability could have been spuriously accounted for due to the persistence of the predictors. The analysis uses a predictive quantile regression model developed by Lee (2016) that allows for persistent predictors. We find that predictability changes remarkably across the entire distribution of currency excess returns. Predictability weakens substantially in the left tail once persistence is accounted for, implying a moderate negative predictive relation between FX volatility risk and carry trade returns. By contrast, it becomes stronger in the right tail. Furthermore, we provide evidence that FX volatility risk still dominates liquidity risk after controlling for persistence. These findings suggest that the persistence of the predictors needs to be taken into account when one measures predictability in currency markets. Finally, out-of-sample forecast performance is also presented. 相似文献

Online-to-offline (O2O) has become a rapidly growing e-commerce model worldwide, but the factors influencing consumers' purchase decision-making have not been examined well. After exploring the working mechanism of the O2O model, we extract eleven indexes of consumers' overall evaluation in the O2O model with Crawlzilla and R techniques. Social network analysis (SNA) is adopted to build social networks reflecting consumers' overall evaluation in the O2O model. Based on the modified social network and the extracted subgraph, this study (N = 768) reveals consumers' overall evaluation behavior patterns in the O2O model by calculating network density, central potential, edge betweenness. The results show that shoppers overall evaluate the eleven indexes, especially perceived product quality, online product price, promotion intensity, business reputation, and product brand, which reflects the significant associations between the indexes. Among all the eleven evaluation indexes, perceived product quality, online product price, and business reputation dominate consumers’ decision-making behavior. When making purchase decisions, consumers not only overall consider online product price, perceived product quality, and business reputation but also balance perceived product quality, business reputation, and promotion intensity. Finally, we make some suggestions on marketing strategy for e-commerce companies. 相似文献

The purpose of this study is to re-conceptualize the conventional marketing mix for Bottom of the Pyramid (BoP) markets and propose a revised framework by reorganizing the elements based on the customer perspective while retaining the principles of services marketing. Primary data was collected through a questionnaire with a sample size of 400 people from both urban and rural markets in the BoP. Findings indicate that the needs and perspective of the BoP members is distinct from the Middle of the Pyramid (MoP). Managers should consider this point while formulating marketing mix strategies for BoP markets. The present study is the first of its kind to present a revised marketing mix framework for customers in the BoP markets. The framework comprises five Ps, including personalization, product, place, the process of service delivery and price. Thus, a theoretical contribution is made in the context of service marketing and the BoP. 相似文献

This study investigates the relationship between auditor tenure and credit default swap (CDS) spreads of U.S. firms based on quantile regression. After allowing for common determinants of CDS spreads, auditor tenure exerts both statistically and economically significant additional impacts on the CDS market. Furthermore, there are differential effects of common CDS spread determinants and auditor tenure. While common determinants of CDS spreads (e.g., leverage, volatility, risk free rate, credit ratings, and earnings) have monotonically increasing impacts when CDS spreads (and their changes) are increasingly higher, auditor tenure primarily has the impact when CDS spreads are of low or median levels for less risky firms. 相似文献

This study examines the global nature of the recent crisis under bivariate Markov-switching models for pre- and post-crisis periods using the breakpoint of August 9, 2007. It quantifies international synchronization of boom-bust regime switches to investigate contagion-type dynamic comovements of Real Estate Investment Trusts (REITs). Global REIT markets display persistent bust regimes from September 2008 to May 2009, whereas the regime-switching patterns are not significant in the pre-crisis period. The results provide new evidence for global REIT contagion phenomena and suggest greater difficulties in diversifying risks across global REIT markets during the post-crisis period. 相似文献

Faultlines can affect a board of director’s effectiveness in supervising senior managers, which in turn affects the value of a company’s cash holdings. Based on sample data from Chinese A-share listed companies from 2004 to 2016, we examine the relationship between board faultlines and the value of cash holdings. The empirical results indicate that board faultlines have a significant inhibitory effect on cash holding value. This inhibitory effect is stronger for board faultlines resulting from deep-level attributes. Furthermore, the inhibitory effect of board faultlines is stronger in state-owned enterprises (SOEs) than in non-SOEs. As an important governance mechanism, management shareholdings can reduce agency costs and mitigate the negative impact of board fissures on cash holdings. Overall, we enrich the literature on the economic consequences of board faultlines and their influence on cash holding value. We also offer companies practical suggestions for improving the supervisory mechanism of their board of directors. 相似文献

Local festivals may leverage local specialties and various historical, cultural, and artistic resources throughout their respective regions to attract tourists, inducing positive economic impacts. In this study, this paper is a first attempt to analyze the relative efficiency of local festival tourism by using parametric and non-parametric approaches with the data from local festivals held in Korea from 2015 to 2018. We also deal with the efficiency determinants of each typology of festivals by employing a truncated regression with double bootstrapping. Results showed that the leading sources of inefficiency were primarily embedded in pure technology inefficiency, while the principal operational drivers posed different effects depending on the typology of festivals. These insights have important practical implications for the local festival organizing committees and operators in Korea and are helpful in developing tailored operational strategies to maximize the efficiency among different typologies of festivals. 相似文献

当市场环境不好以及不确定性增加时,基金进行安全投资转移。企业积极履行社会责任所形成的声誉资本具有“类保险”作用,在面临负面事件或不确定性环境冲击时能够防止股价大幅下跌和市值损失;基金是否会在市场环境不好时将投资组合转向社会责任绩效更高的股票进行安全投资转移呢?使用2010—2017年开放式基金样本,实证检验了企业社会责任、市场环境与安全投资转移之间的关系。研究发现,在市场环境表现不佳时,基金避险需求增加,倾向将投资组合更多地转向社会责任绩效高的股票进行安全投资转移;进一步研究发现基金和基金经理特征影响基金的安全投资转移行为,净资金流入较少、历史业绩差、经理选股能力差的基金根据企业社会责任进行安全投资转移的程度大。研究还发现,基金的安全投资转移行为对基金业绩和基金收益波动产生了积极影响。 相似文献
