关于发展我国市政债券及市场的几点思考

我国＂十二五＂期间将积极稳妥推进城镇化,提升城镇发展质量和水平。在资金来源渠道有限的情况下,我们可以借鉴美国发行市政债券促进地方城市基础建设的经验和做法,改变我国城镇基础建设设施落后,投入不足的现状,按照市场经济的要求,逐步建立市场化、多渠道、多层次的资金筹措新体制。通过发行市政债券将更多的社会资金引入公共部门,推动我国城镇化进程。     

Marketing Period Risk in a Portfolio Context: Comment and Extension

This paper re-examines and extends the findings of Bond et al., Journal of Real Estate Finance and Economics, 34, 447–461, (2007) who consider the theoretical model of Lin and Vandell, Real Estate Economics, 35, 291–330, (2007) to determine the extent to which individual real estate asset return characteristics caused by marketing period risk disappear in a large, diversified real estate portfolio. The effects of marketing period risk are found to disappear in the limit with growth in the size of the portfolio, with ex ante variance approaching ex post variance, but only if the portfolio consists of nonsystematic risk alone, in which case both approach zero. The marketing period risk factor (MPRF), representing the ratio of ex ante to ex post variance, however, does not in general approach zero in the limit, in fact could increase or decrease depending upon the illiquidity characteristics of the individual assets and the magnitude and degree of correlation among individual property returns and marketing periods. The results suggest that even large institutional real estate portfolio managers must consider the illiquidity present in their portfolios and cannot assume that its effect will be diversified away.

Distance in time between transition economies and the European Union

The time distance methodology used offers a new perspective to the problem, an additional statistical measure, and a presentation tool for policy analysis and debate readily understood by policy makers, media and general public. Disparity between the analysed transition economies and EU countries is considerably smaller for other indicators than for GDP per capita. Compared with Ireland, Portugal and Greece Slovenia was in 1995 in 13 cases behind (but time lag of Slovenia never exceeded 10 years) and in 13 cases ahead of them. Sicherl (1997a) discusses application of S-distance to time series regressions, models, forecasting and monitoring. First version received: October 1995/final version received: April 1998

Aircraft and passenger recovery during an aircraft’s unexpected unavailability

Airlines design their initial schedules under the assumption that all resources will be available on time and flights will operate as planned. However, some disruptions occur due to mechanical failures and unexpected delays of maintenance, making the aircraft unavailable for a certain period of time. These deviations from the initial plan result in high operational costs in addition to the serious inconveniences experienced by passengers. In order to handle aircraft and passenger recovery problems simultaneously, we work on integrated networks at which aircraft routings and passenger itineraries are superimposed. Consequently, we could calculate the actual profit and cancellation cost by evaluating each passenger itinerary while considering the seat capacity limitations. In our computational results, we use a daily schedule of a major U.S. airline and clearly demonstrate that there is an optimal trade-off between operating and passenger-related costs.     

心理契约违背对饭店顾客忠诚的影响——服务补救策略的调节效应

针对服务企业普遍面对的服务补救低效与顾客忠诚保持的挑战,文章基于心理契约与前瞻性服务补救理论,构建了顾客心理契约违背、服务补救和顾客忠诚间关系的分析框架,实证分析了心理契约违背对顾客忠诚的作用机理,并检验了服务补救策略对这一关系的调节效应。通过对262名饭店顾客的问卷调查,采用回归分析法处理数据,研究结果表明:心理契约违背两个维度与饭店顾客忠诚两个维度均呈显著负相关关系,顾客心理契约违背程度越高,顾客忠诚度越低;服务补救在心理契约违背与饭店顾客忠诚的关系中起到部分调节作用,即当企业服务出现失误而使顾客感知心理契约违背发生时,如果能采用恰当的服务补救策略,可以降低心理契约违背对顾客忠诚的负面影响。
