Early warning indicators? The effect of consumer and investor sentiments on the restaurant industry

This study looks at the influence of cyclical fluctuations of the consumer confidence index (CCI) and the volatility index (VIX) as early-warning indicators of the variations in restaurant performance. The industry has traditionally focused on past data and on microeconomic influences to anticipate its future performance, a procedure that does not consider possible cyclical fluctuations in restaurant performance metrics. These fluctuations are driven by sentiments of consumers and investors. The study uses the cyclical component of the applied data, followed by unit root and cointegration testing, with subsequent application of the Limited Information Maximum Likelihood technique. The results show both indicators have an effect on restaurant performance, where VIX has an impact on the current, expected, and overall restaurant performance, while the CCI’s influence is only partial (current performance). Policy-makers and planners could benefit from anticipating features of indicators to assess and steer the future performance of the restaurant industry.     

上海金融发展与经济增长关系的实证研究

本文从实证上研究上海金融发展与经济增长之间的长期和短期关系。协整检验、格兰杰因果关系检验和误差修正模型估计结果表明,上海金融发展与经济增长存在着长期稳定的均衡关系,上海金融发展的规模、结构、效率与经济增长之间存在单向因果关系,即经济增长是金融发展规模的格兰杰原因、金融发展结构是经济增长的格兰杰原因、经济增长是金融发展效率的格兰杰原因,滞后2期的金融发展的效率是经济增长的格兰杰原因。从短期来看,上海金融发展对经济增长的影响也是比较显著的。基于以上研究结论,本文提出完善上海金融结构与提高金融效率的政策建议。     

我国纺织品出口对经济增长贡献的实证研究

出口贸易是影响经济增长的重要因素。本文采用1980-2004年的数据,描述了我国纺织品出口的特点,并借助协整模型实证研究了纺织品出口对经济增长的影响,指出二者之间存在长期的动态关系。通过定量分析,发现纺织品出口对经济增长的直接拉动度和贡献率都较低,这是因为我国纺织服装行业一方面受宏观环境影响,另一方面自身竞争优势不足。本文经过研究,形成了对我国纺织品出口与经济增长之间关系直观而清晰的认识,并为无配额时代我国纺织业发展的后续研究提供了参考。     

我国进出口贸易关系的时间检验

本文运用E-G两步法,分析我国自1951年至2003年期间对外贸易出口总额和进口总额之间的关系。实证分析表明:进口总额和出口总额之间存在长期稳定的均衡关系,通过格兰杰检验发现,进口总额和出口总额之间还存在双向的格兰杰因果关系。本文在协整分析的基础上建立误差修正模型,分别从长期和短期对两者之间的关系进行定量分析。     

Estimating the long-term effects of advertising on sales: a co-integration perspective

Co-integration econometrics have important theoretical advantages over more traditional approaches to estimating the long-term effects of one variable on another. When advertising and sales data are co-integrated, adaptations of common econometric procedures may be used to estimate the long-term effects directly rather than inferring them from short-term relationships. This paper presents a method for detecting and estimating co-integrating relationships using ordinary least-squares regression procedures. The method is illustrated with the well-known Lydia Pinkham data from 1907 through to 1961. The results show that there was a strong positive relationship between Lydia Pinkham advertising and sales in the long-term. Implications of the method and findings are discussed.     

改革开放以来影响广东省外贸出口因素的实证分析

本文分析了广东省外贸出口与进口、FDI、出口对象国的经济增长及人民币名义汇率等影响因素的长期均衡关系,然后分析了短期中广东省外贸出口量对各影响因素波动的反应。得出结论:长期中,广东省出口额与外国收入、进口额、人民币名义汇率之间存在着正相关关系,而短期内进口额和人民币名义汇率对出口影响较大。     

“港股直通车”对两地股市影响的实证分析

本文以股权分置改革后的最新数据为研究对象,首先剖析了香港股市与内地股市的高度关联性,然后运用计量经济方法检验两地股市的相关性、以及“港股直通车”前后两地股市关系发生的变化,从而得出结论：在当前背景下,不宜推出“港股直通车”。这也证明了中央暂停港股直通车的合理性与及时性。     

民间投资与产业转型——以浙江省为例

本文以浙江省为例,利用浙江改革开放后30多年的数据资料,对民间投资比重和三次产业的比重进行协整建模分析,分析结果表明,民间投资对浙江三次产业结构的变化起到重要的作用。民间投资比重上升是拉动浙江第三产业比重上升的原因,从而也说明了浙江第三产业的发展主要是依靠民间资本的投入;但对第二产业而言,民间投资对其的作用是反向的,这说明浙江第二产业的发展主要不是依靠民间资本的投入,而是依靠政府的投资。     

Speculative bubbles in emerging stock markets and macroeconomic factors: A new empirical evidence for Asia and Latin America

The purpose of this study is firstly to test for the existence of periodically collapsing stock price bubbles in Asian and Latin American emerging stock markets for the period 1990–2009. We use the new non-cointegration test developed by Taylor and Peel (1998) with the Residuals-Augmented Least Squares (RALS) method of Im (1996) and Im and Schmidt (2008) for monthly data of price indexes and dividends. The results show that the hypothesis of formation of bubbles cannot be rejected for all of the studied emerging stock markets. This evidence implies that the co-integration relation between the prices and the dividends is not always supported, indicating that the stock prices do not reflect their fundamental values in the emerging stock markets. We then link speculative bubbles with macroeconomic and financial factors, which is an interesting contribution of this study. The degree of equity market openness is found to be the key factor, positively related to the formation of speculative bubbles in these markets.     

FDI的资本效应与溢出效应之比较——基于中国数据的协整分析

本文利用一个修正的经济增长分析框架,同时容纳FDI对经济增长的直接资本效应和间接溢出效应,然后在协整检验的基础上,使用向量误差修正模型、冲击响应函数和Granger因果关系检验等方法,对中国1983-2007年间的数据进行实证研究,考察了GDP和其他多个经济变量之间的长期和短期均衡关系,并且对FDI的两种效应做出了比较分析。研究发现,FDI的资本效应比较明显,而溢出效应比较微弱。
