基于EKC的水资源利用与经济增长关系研究

基于环境库兹涅茨曲线(EKC),采用中国31个省市区2005-2012年水资源利用量和经济增长相关指标的平衡面板数据,通过模型验证水资源利用量EKC在中国是否存在.分析得出:①人均用水总量和人均农业用水量EKC不存在;②人均工业用水量EKC存在,转折点为23615.34元,且人均GDP可以作为人均工业用水量的预测指标;③人均生活用水量EKC并不存在.因此,在促进经济增长的同时,要注重水资源利用量与经济增长的内在关系,降低EKC转折点,以缩减用水量.     

江苏失业与物价水平权衡关系的实证研究

保持经济持续增长、物价水平基本稳定和实现充分就业是政府经济宏观调控的主要目标。文章基于江苏省物价水平的自相关性,建立了滞后一期的附加预期的菲利普斯曲线模型,使用江苏1987-2011年的CPI数据和城镇登记失业率,实证测算了江苏省物价水平、失业率以及物价水平预期之间的关系和相关检验。通过研究发现,在江苏省物价水平上升1%时,在保持物价水平预期不变的情况下,失业率可下降0.532%,失业率对当期物价水平的影响度为74%,物价水平预期对当期物价水平的影响度为26%。因此,江苏省政府部门应当在控制失业率和保持物价稳定的同时,寻求三者之间的最佳结合点,使物价与失业保持适度均衡。     

期货市场量价关系：基于分位数回归模型的实证研究

本文采用分位数回归来分析上海期货市场以及伦敦期货市场收益率和成交量之间的关系。实证结果发现两地期市的量价关系不同：伦敦期货市场的量价关系并不明显;上海期铜呈现“量价齐扬”以及“价跌量亦涨”的现象;上海期铝只呈现“量价齐扬”的现象,价跌时量价关系不明显;上海金属期货市场的收益率与成交量呈现非对称的“V”字型关系。进一步的分析表明,两市场量价关系的差异是由投资者结构不同导致的。

Arbitrage bounds for the term structure of interest rates

This paper proposes a methodology for simultaneously computing a smooth estimator of the term structure of interest rates and economically justified bounds for it. It unifies existing estimation procedures that apply regression, smoothing and linear programming methods. Our methodology adjusts for possibly asymmetric transaction costs. Various regression and smoothing techniques have been suggested for estimating the term structure. They focus on what functional form to choose or which measure of smoothness to maximize, mostly neglecting the discussion of the appropriate measure of fit. Arbitrage theory provides insight into how small the pricing error will be and in which sense, depending on the structure of transaction costs. We prove a general result relating the minimal pricing error one incurs in pricing all bonds with one term structure to the maximal arbitrage profit one can achieve with restricted portfolios.

Determinants of spreads on new high yield bonds of shipping companies

This paper investigates determinants of pricing of new high yield bond offerings of shipping companies. New high yield bond offerings issued by shipping companies in the US market, during the period 1993–1998, are used in the investigation. The empirical results suggest that credit rating is the major determinant of the price spread of the bond offerings. Financial leverage and shipping market conditions also account for a significant part of the price variability.     

Investigating Rate Integrity in Convention Cities

Abstract

Yield Management (YM) is the utilization of tactics to align a consumer product within the market for profit maximization. By evaluating how rates are quoted to consumers, the effectiveness of YM tactics can be delineated. This study compared central reservation (CR) telephone and Internet room rates by city. The CR centers for full-service hotels in 19 different cities were contacted by telephone to request a room. The CR rates were compared to rates obtained from the hotels' Internet sites. The data analysis found significant differences in reservation rates by city and by size of the lodging property. Hoteliers can use the information to evaluate the effectiveness of their YM systems.     

Meeting revenue management challenges: Knowledge,skills and abilities

Hospitality industry increasingly recognizes importance of integrating revenue management into their operations and significance of their staff to do so. Yet revenue managers face major challenges from both internal and external sources. Hence revenue staff dealing with several sophisticated problems should possess various knowledge, skills and abilities (KSAs) to enable them effectively overcome these obstacles. However which specific capabilities are required to what extent are not clear. Therefore this study aims to match the challenges that are faced by hotel revenue managers with KSAs required in managing inventory and prices. A two step qualitative method is adopted; first 14 revenue managers were interviewed and secondly a focus group with eight participants was conducted in order to identify challenges and competencies required in improving revenue management effectiveness. Thus this study offers a typology of challenges faced by revenue managers and it also identifies KSAs that are required by revenue management staff.     

Input‐output analysis and income distribution patterns of the tourism industry in South Korea

This study estimates the economic effects of the tourism industry in South Korea by using the Input‐Output Model in terms of output, income, employment, value added, indirect tax, and import The distribution of income is also examined in the tourism industry among various social classes using the Lorenz curve and the Gini coefficient The results show that the tourism industry performed better than most of other industries in terms of generating employment and tax revenues. The tourism industry also performs better in terms of minimizing leakage, but more poorly in terms of the linkage effect as compared to the majority of other industries. The Gini coefficient and the Lorenz curve show that the tourism industry performs moderately well in the distribution of income among household income classes as compared to the majority of other industries.
