When quality signals talk: Evidence from the Turin hotel industry

This study analyzes the relationship between quality signals and price setting through the application of hedonic price functions. The model proposals also include variables relating to land use policies and tourism development strategies. A simultaneous equation model endogenously estimates quality signals. This method is appropriate for analyzing emerging urban destinations, as characterized by the presence of an expanding hotel industry. The results are based on a dataset of 145 hotels in Turin, Italy. The empirical findings reveal that reputation-based quality signals help explain tariff levels. Price proposals also include a premium for quality assured hotels, defining some limits of the current hotel classification system. The empirical evidence has significant marketing implications for the hospitality industry’s competitiveness, since the results clarify the impact of quality signals on price level.     

Impact of financial/economic crisis on demand for hotel rooms in Hong Kong

The main objectives of this study are (1) to identify the factors that influence the demand for hotel rooms in Hong Kong and (2) to generate quarterly forecasts of that demand to assess the impact of the ongoing financial/economic crisis. The demand for four types of hotel room from the residents of nine major origin countries is considered, and forecasts are generated from the first quarter of 2009 to the fourth quarter of 2015. Econometric approaches are employed to calculate the demand elasticities and their corresponding confidence intervals, which are then used to generate interval demand predictions. The empirical results reveal that the most important factors in determining the demand for hotel rooms in Hong Kong are the economic conditions (measured by income level) in the origin markets, the price of the hotel rooms and the ‘word of mouth’ effect. Demand for High Tariff A and Medium Tariff hotel rooms is estimated to have experienced negative annual growth in 2009 due to the influence of the financial/economic crisis, whereas that for High Tariff B hotel rooms is thought to have grown in 2009 after having decreased in 2008. The demand for tourist guesthouse rooms is expected to be the least affected by the crisis. Overall demand is predicted to recover gradually from 2010 onwards.     

Market structure and demand-side substitutability of chained urban hotel segments

This study analyzes how the demand in hotel markets is divided amongst chained hotel segments. Hypotheses regarding consumers’ switching behavior due to changes in income levels and relative prices are tested using data from 25 major urban markets in the United States, encompassing segments ranging from luxury to economy over 43 quarters. The effects of differentiation and market concentration are also investigated in this context. The results suggest that leisure and individual consumers of the low-scale segments may be trading “up” to higher scales when their income increase, but that upscale segments’ corporate consumers are not necessarily trading “down” when Corporate Income fall. In addition, only low-scale segments appear to be substitutes to upscale segments, but the inverse seems not to be true. Also, properties in mid-range segments are found to be the only ones benefiting from a high market concentration, while low-scale properties turn out to be the ones gaining from differentiation through price.     

Pricing-to-Market: Price Discrimination or Product Differentiation?

We employ a vertical differentiation model to examine the potential bias in pricing-to-market results when using export unit values aggregating differentiated products. Our results show that: (i) false evidence of pricing-to-market is always found when using unit values, whether the law of one price holds or not; and (ii) the size of the bias increases with the level of product differentiation. Our simulation results support those conceptual findings. Thus, some of the positive pricing-to-market results in the literature could be an artifact of the product heterogeneity embodied in unit values rather than evidence of imperfect competition.     

对我国CPI构成的探讨

消费物价指数是反映一国物价水平变动的重要指标,也是制定宏观经济政策的主要依据。本文主要从我国9月M1和CPI偏离出发,介绍了我国CPI构成,指出了我国CPI构成中存在的问题主要包括食品类权数过高和购房价格未包含入消费物价指数中,并有针对性提出相应的调整建议。

Exploitation of Renewable Energy in the Hospitality Sector: Case Studies of Gaborone Sun and the Cumberland Hotel in Botswana

This study examines the factors influencing the adoption of renewable energy technologies at two hotels in Botswana. Interviews with key informants from Gaborone Sun and the Cumberland Hotel were used to collect the data for this study. The study was designed along the general conceptual model of the drivers and barriers of corporate “greening.” Narrative analysis was used to present the findings. Results point to the fact that the availability of the biogas and solar technology in Botswana, political leadership, financial benefits, the availability of a comprehensive environmental sustainability program, and strong environmental management values were the driving forces behind renewable energy adoption by the two hotels. The major barriers against biogas adoption by the Cumberland Hotel included lack of financial resources and limited waste. For solar energy adoption at Gaborone Sun, the main problem was lack of space for further expansion, which has also constrained the hotel’s efforts for wastewater recycling. These results have implications at both local and national levels. Environmental management strategies and values should drive the exploitation of renewable energy by local hotels. At the national level, results imply that the government should take a more responsive approach in facilitating the adoption of renewable energy plans by the corporate world.     

旅游经济增长及其溢出效应的空间面板计量经济分析

文章首次基于空间面板计量经济学模型,在检验我国省域旅游经济增长是否存在空间依赖性的基础上,估计了资本和劳动对旅游经济增长的贡献,检验了旅游经济增长过程中的空间溢出效应。研究结果显示:2001~2009年间,中国省域旅游经济增长的空间依赖性和集群趋势加强,邻近省域的经济增长及旅游资本投入的空间溢出效应明显;资本和劳动的旅游产出弹性系数均为正,前者对旅游经济增长的贡献大于后者,我国省域尺度的旅游经济增长主要依赖于资本要素投入驱动,呈现出资本密集型特征,劳动力要素的贡献尚未充分发挥出来。政府在制定旅游产业政策和发展规划时,必须致力于加强邻近地区旅游资本和劳动投入的合作与交流,促进旅游经济增长中的资本空间溢出效应,改革旅游业国民收入初次分配及再次分配体制,激活邻近省域旅游劳动力投入与旅游经济增长的空间互动性,以便提高邻近地区及本地区劳动力对旅游经济增长的协同贡献。     

Market shares analysis: The Case of French Tourism Demand

This paper examines the magnitudes and determinants of changes in destinations’ shares of a major tourist origin market. The Almost Ideal Demand System model is used to quantify the responsiveness of French tourism demand in Italy, Spain, and the United Kingdom to changes in relative prices, exchange rates, tourists’ expenditure budget, and external events. The results indicate that effective price competitiveness is a key variable driving changes in market shares. Policymakers who wish to maintain their shares of the French market should pay particular attention to tourism pricing policies, as well as to improving the tourism offer.
