基于多视角的我国东北三省工业产业结构趋同问题研究

产业结构调整是加快经济发展的核心问题,是经济高速增长的基本推动力量。因此深入研究地区产业结构趋同问题,对于地区产业结构调整以及产业结构高级化发展具有重要意义。本文利用东北三省合并后23个工业产业2001～2014年的工业总产值数据,通过产业结构相似系数、区位熵以及β趋同系数多角度分析东北三省工业产业结构趋同问题。从发展方向看,我国东北三省合并后23个工业产业相似系数最高的是辽宁和黑龙江省,最低的是吉林和黑龙江省,从专业化水平及总量和发展速度关系看,东北三省工业产业在农副食品加工业、交通运输和通用设备制造业形成了区域优势,但在低附加值、产业链低端的开采业以及劳动密集型产业上还存在不同程度趋同,并提出东北三省工业产业在转型升级中应当重点发展高加工度、高附加值等产业,避免产业间的低端雷同的政策建议。     

Assessing time-varying stock market integration in Economic and Monetary Union for normal and crisis periods

In this paper, we examine the stock market integration process amongst 17 Economic and Monetary Union (EMU) countries from January 2002 to June 2013 over a normal period as well as for the Global Financial Crisis (GFC) and Eurozone Debt Crisis (EDC) periods. We classify the economies in three groups (A, B and C) based on their GDP to examine whether the economic size influences financial integration. Seven indicators are used for the purpose, namely, beta convergence, sigma convergence, variance ratio, asymmetric DCC, dynamic cointegration, market synchronisation measure and common components approach. The results suggest that large-sized EMU economies (termed as Group A) exhibit strong stock market integration. Moderate integration is observed for middle-sized EMU economies with old membership (termed as Group B). Small-sized economies (termed as Group C) economies seemed to be least integrated within the EMU stock market system. The findings further suggest presence of contagion effects as one moves from normal to crisis periods, which are specifically stronger for more integrated economies of Group A. We recommend institutional, regulatory and other policy reforms for Group B and especially Group C to achieve higher level of integration.     

Preparing for higher inflation: Portfolio solutions using U.S. equities

Investors have always been interested in reducing inflation risk in their portfolios. However, investors face different types of inflation than those measured by the Consumer Price Index (CPI). Moreover, different asset classes can be used to hedge portfolio inflation. In this paper, we show how individual equities can be used to construct equity portfolios sensitive to customized inflation targets. We illustrate portfolios for three types of inflation: US headline CPI, Forbes Cost of Living Extremely Well Index, and the US Medical Care Price Index. We also show how alternative weighting schemes, such as minimum volatility and maximum inflation beta, can be used to construct inflation‐hedged portfolios.     

Does High Service Quality Reduce Risk or Create Idiosyncratic Returns?

This article explores the impact of service quality on idiosyncratic returns, idiosyncratic risk (nonsystematic risk), and beta (systematic risk). Service quality was derived from the airline quality rating, and three dependent variables were calculated by the Fama–French four-factor model. The data includes 1,512 monthly records from 1997 to 2006, across 21 airlines. Multiple regression and vector autoregressive models were applied to test relationships among all, low-cost, and non-low-cost airlines. The study found that service quality has a positive impact on idiosyncratic returns in non-low-cost airlines; non-low-cost airlines are less affected by changes in the external environment.     

Empowerment in hospitality organizations: Customer orientation and organizational support

Although empowering employees has often been prescribed as an efficient strategy for hospitality organizations, the strategy alone cannot ensure success. Individual and organizational factors should be considered to increase employees’ perception of empowerment. This study examines the impact of employees’ customer orientation and organizational factors on the employee empowerment perceptions. Our findings, based on a survey of 203 guest contact employees, suggest that organizations should hire customer oriented people, guide them with service training, provide a reward system, and facilitate service standards communication in order to increase perceived empowerment. Implications of these findings for hospitality service managers are discussed.     

On the two-sided power distribution

This paper concerns a two-parameter two-sided power distribution introduced by van Dorp and Kotz on the interval [0,1]. We introduce a reformulated two-sided power distribution (with the same number of parameters) and provide evidence to prove that it is more flexible than the one suggested by van Dorp and Kotz. We derive various properties of the new distribution as well as provide several hitherto unknown properties of the distribution due to van Dorp and Kotz. We also discuss estimation by the method of moments and the method of maximum likelihood.Received September 2003

The extent of nonstationarity of beta

This paper investigates the extent of nonstationarity of beta across the firm size and the beta magnitude by suggesting the sequential parameter stationarity model and estimating change-points of betas. The high-beta firm has shorter stationary interval, which means that its beta changes more frequently than do the low-beta firm's. The firm size, however, does not have a monotonic relation with the length of stationary interval. The small and large firms have relatively shorter stationary interval than do the mid-sized firms. The average length of stationary interval is estimated about five years (exactly 54.19 months). This fact could support the currently widely-used arbitrary 5-year assumption of beta stationarity. The fluctuation of the large firm's beta is more severe than the small firm's, and the high- and low-beta firms have the relatively greater fluctuating betas than do the mid-beta firms. The frequency of detected change-points is found to be positively related to market returns. When the market return is high, the systematic risk changes more frequently, and vice versa.

Investigating the impact of surprise rewards on consumer responses

Adopting an experimental approach, this research compared surprise rewards with membership discount rewards in terms of their impact on customer responses of delight, frustration and satisfaction. In addition, this research examined the circumstances under which surprise rewards should be offered in order to yield maximum benefits for hospitality firms. In particular, the study examined how the customer's cumulative satisfaction (high vs. low) influences the effectiveness of surprise rewards (vs. membership discount rewards) in increasing customer delight and satisfaction and decreasing customer frustration. Consistent with the theoretical predictions, results show that surprise rewards are more effective than membership discount rewards for enhancing customer delight and satisfaction and attenuating customer frustration, particularly when the customer's cumulative satisfaction is low. These findings have important implications for the hospitality industry. Hospitality managers and marketers could use this information to design effective loyalty reward programs.
