沪深300股指期货定价实证研究

股指期货是一种发展迅速的金融衍生产品,而合约定价问题是其重要研究方向之一。股指期货定价的基本方法是利用无套利定价原理得出的持有成本模型;而如果综合交易费用、融资成本、存贷款利差、保证金等市场因素,则可以得到股指期货的无套利定价区间。使用这两种模型对中国金融期货交易所的沪深300股指期货仿真交易合约进行实证分析,结果发现,实际交易价格和理论价格有较大偏差,市场中存在大量套利机会,定价效率有待提高。为此可以考虑的建议包括允许融资融券交易、推出沪深300指数ETF等。     

Housing Vouchers,Tenant Quality,and Apartment Values

Landlords face unique concerns in maximizing profits when they accept subsidized as well as unsubsidized tenants. Subsidized tenants come with lower rental collection risk because part or all of the rent is paid by a public agency and accepting subsidized tenants may widen the potential tenant market. But subsidized tenants tend to reduce overall tenant quality and to impose higher operating costs. By accepting subsidies, landlords may also subject themselves to periodic site inspections that may increase capital costs. Further, subsidized tenants may eventually crowd out unsubsidized tenants, lowering the average quality of the resident mix. Tests from Washington, DC apartments on accepting and advertising for Section 8 tenants support these qualitative predictions. Accepting Section 8 tenants enhances revenues, but advertising for them lowers revenues. More aggressive solicitation of subsidized tenants leads to a crowding out or displacement risk that dominates over any diminished collection risk.     

汇率制度选择理论的回顾与展望

汇率制度选择一直是国际金融领域备受关注的一个问题.文章对汇率制度选择的研究方法及视角进行了总结,并对传统的汇率制度选择理论和汇率制度的新进展进行了论述,进而对未来汇率制度选择的研究进行了展望.认为:由于存在"恐浮",应该依据实际实行的汇率制度而不是官方宣布的汇率制度进行研究;从动态角度进行汇率制度转换的研究也是很重要的发展方向;应该对中间与两极汇率制度进行统一的界定,建立支持或反对"中空论"的严格理论框架.     

日本企业的海外投资与经验借鉴

同中国一样,日本企业进行海外投资也是一个渐进的过程。随着投资规模的不断扩大,日本企业积累了丰富的海外运营经验。本文依据投资规模将日本企业海外投资的过程划分为七个阶段,通过分析各阶段日本企业跨国经营的动因和特点,总结日本企业海外投资的成功做法,希望能够为正在实施“走出去”战略的中国企业提供借鉴。     

基于挤出效应的住房保障规模对商品住房价格的影响

中国房地产市场中保障性住房的角色和作用愈加重要,保障性住房建设规模正在逐年扩大.商品住房价格变化是供给需求作用的结果,但是随着保障房供给规模的增加,商品住房价格的涨幅也会发生改变,说明保障房的供给规模会对普通商品房的供需产生影响.本文以北京市商品住房市场为例,选取住宅需求、住宅供给、住房投机对价格的影响为自变量,住宅价格为因变量,利用多元回归模型对商品住房价格变化进行实证研究,同时通过考虑保障房供给对住房市场产生的不同挤出效应,分析保障房供给规模供需变化对房价产生的影响,进而为政府制定相关的住房保障政策提供建议和对策.     

From carry trades to curvy trades

Traditional carry trade strategies are based on differences in short-term interest rates, neglecting any other information embedded in yield curves. We derive return distributions of currency portfolios, where the signals to buy and sell currencies are based on summary measures of the yield curve. We find that a strategy based on the relative curvature factor, the curvy trade, yields higher Sharpe ratios and a smaller return skewness than traditional carry strategies. Curvy trades build less upon the typical carry currencies and are hence less susceptible to crash risk. In line with that, standard pricing factors of traditional carry returns fail to explain curvy trade returns.     

Does the choice in valuation method matter in the judicial appraisal of private firms?

This paper investigates empirical relations between the redemption values of minority shares and valuation methods used by dissenting parties in the judicial valuation of private firms. We examine a comprehensive data set of Finnish judicial appraisal cases in which the judge decides the valuation of the minority stake in a private firm after learning the valuation estimates put forward by the controlling shareholder(s) and the minority shareholder(s). Rationality in valuation will be achieved if a valuation estimate incorporates all the available information regardless of the valuation method adopted. Conversely, the measurement perspective argues that biases inherent in valuation approaches determine the information content in a valuation estimate. Our statistical analyses suggest that the choices made concerning the valuation method are statistically correlated with the appraisal outcomes. We interpret this as evidence consistent with the measurement perspective.     

The moderating impact of perceived globalness on consumers’ purchase intentions for copycats: The pleasure of hurting global brands

Copycats or “me‐too” brands imitate prominent features of market leaders with the intention to benefit from consumers’ positive associations of the imitated brand. However, the imitated market leader can be perceived as being local (=in‐group) or global (=out‐group). Employing social identity theory, Study 1 examined the interaction between copycat strategy and perceived globalness of the brand, showing that consumers have higher purchase intentions for global copycats versus a local counterpart. Study 2 shows that the interacting effect of copycat strategy and perceived globalness is moderated by consumer ethnocentrism. Further, authors demonstrate that a global copycat elicit greater schadenfreude (vs. local brand), which in turn increases consumers’ purchase intentions. Subsequent mediation analysis shows that ethnocentric consumers experience schadenfreude upon encountering copycats of global brands, which in turn increases purchase intention, whereas low ethnocentric consumers show higher purchase intentions for local differentiated brands because they deem a copycat strategy as unacceptable. Finally, Study 3 examines whether the results from Studies 1 and 2 continue to hold for theme copycats.     

Fear of missing out and compulsive buying behavior: The moderating role of mindfulness

The current study investigates the relationship between the fear of missing out (FoMO) and depression, anxiety, materialism, and compulsive buying behavior (CBB). Furthermore, the study also investigates the potential moderating role of mindfulness in the relationship between FoMO and outcomes. A self-administered questionnaire was used to obtain data from 569 participants, and structural equation modeling was used to analyze that data through SmartPLS. The finding showed that FoMO has a positive and significant effect on CBB, whereas depression, social anxiety, and materialism partially mediate the relationship between FoMO and CBB. Additionally, mindfulness has a significant moderating role in the relationship between FoMO and negative consequences. This study underscores the significance of mindfulness-based interventions in mitigating the adverse effects of FoMO on depression, social anxiety, materialism, and CBB, among adults.     

Fear Of Missing Out Scale: A self-concept perspective

Fear of missing out (FOMO) is an emerging topic in consumer psychology. However, the theoretical foundations of FOMO are underdeveloped and extant FOMO scales confine the construct to the context of social media. Without a theoretical foundation and a new FOMO scale, the future development of research on this promising phenomenon is limited. This article provides a new conceptualization of FOMO and a new FOMO scale. Using self-concept theory, the authors propose that FOMO is an emotional response to perceived psychological threats to one's self-concept. Because the self-concept involves a private and a public self, FOMO involves two dimensions: a personal FOMO and a social FOMO. Accordingly, a new scale was developed. The results of four studies support the validity and reliability of the two-dimensional scale. This new conceptualization and scale will enable consumer researchers to examine FOMO in a broader set of contexts, test the relationship between FOMO and related constructs, and develop a nomological network around the construct.
