文章采用我国1994--2010年时间序列数据,在VAR模型的基础上,对CPI与粮食价格指数之间的动态关系进行了实证分析。研究结果表明:我国CPI与粮食价格指数存在双向互动关系,CPI推动了粮食价格指数的增长,同时粮食价格指数也推动了CPI的增长。根据上述实证分析,提出了控制粮食价格上涨的主要对策和建议:建立完善的耕地保护机制,保障基本的种粮面积;加大保障粮食生产投入,提高农民种粮积极性;控制农资产品价格,建立完善的农村金融体系;加强对粮食市场的宏观调控和综合管理。 相似文献

DSSW模型描述了在理性交易者和非理性交易者数量相等的设定下,正反馈交易者的交易行为以及金融资产价格的波动情况.针对中国股市特征,建立了扩展的六状态DSSW模型,讨论了信息交易者利用信息优势,借助正反馈交易者的跟风行为,操纵股价大幅波动,获取超额收益的行为.利用该模型分析了“庄家”内幕交易的五个阶段及其特征,据此提出建议:完善信息披露机制,加强对特殊波动股票的监控,改变股票盈利模式,树立价值投资理念. 相似文献

资产负债表效应是股票价格影响投资的重要渠道。股票价格的波动除了会通过影响托宾Q值而影响上市企业的融资成本,进而影响上市企业的投资外,还会通过影响企业的净值进而影响企业从银行获得贷款的能力而影响企业的投资。而投资是总需求的重要组成部分,也是股票价格影响物价水平的重要方面,因此,研究股票价格对投资的影响,即对资产负债表效应的研究,对于研究股票价格对物价稳定的影响具有重要的理论意义和实践价值。 相似文献

The objective of this paper is to explain geographical divergences in interest rates on personal loans to households using aggregated consumer knowledge-related metrics as predictors. The researchers quantitatively test their approach in countries in the Eurozone and in the Italian and Spanish regions. Social expertise explains between 69% and 84% of variance in household loan market prices at an international and inter-regional level. The approach taken is tested using real market data established after real service encounters and not published or recommended prices. 相似文献

In this paper, the impact of two service quality metrics (star rating and customer rating) on hotel room sales and prices is investigated. Two of the most popular tourist destinations in the world, Paris and London, are chosen. It is found that a higher customer rating significantly increases the online sales of hotels. The study results show that a 1% increase in online customer rating increases Sales per Room up to 2.68% in Paris and up to 2.62% in London. Contrary to expectations, higher stars do not increase the sales. It is also shown that higher customer ratings result in higher prices of the hotel and the prices of high star hotels are more sensitive to online customer ratings. 相似文献

ABSTRACTThis article examines world rice price transmission and volatility spillovers across six major Asian rice markets over the period 2005-13. In addition to the conventional GARCH models, we use a panel GARCH framework to estimate the spillover effects along with the consideration of heterogeneity and interdependence among countries. Empirical results suggest that changes in the world rice price affected not only the price levels of domestic rice markets but also their conditional variances. Moreover, interdependence across rice markets contributed to a strong spillover of a price shock in one country to another within the region. 相似文献

This article provides an exercise for students to contemplate the effects of inflation during financial statement analysis. Even small amounts of inflation accumulating over time can grow to distort a company's reported financial position and results of operations. The growing economies in emerging markets, the international market for oil, and other economic factors threaten to increase inflation rates in the future. As a result of changing global conditions, interest in inflation accounting is expected to increase. The exercise we suggest in this article provides an efficient tutorial on the potential effects of inflation on financial statement analysis and on the application of International Accounting Standard 29 in hyperinflationary environments. 相似文献

The travel industry is currently experiencing a major transition as distribution channels change in response to developments in information technology. This study investigated whether online travel agents (OTAs) can offer air tickets with different prices given the lower search costs made possible by the Internet. This investigation first examined the hypothesis that price dispersion does not exist in air ticket offerings by OTAs. Hedonic regression models with log-linear form are then built to explain the pricing characteristics of air tickets. After accounting for differences in ticket attributes, ticket prices were found to vary by as much as 1.859% across OTAs. In other words, different OTAs were offering identical tickets at different prices. Statistically, significant interaction effects existed between airlines and OTAs, suggesting that travelers with specific airline preferences should expect to find different prices on different OTAs, even when ticket attributes are identical. This work thus revealed imperfections in the online air ticket market. It is therefore necessary for fare conscious air travelers to search different web services provided by OTAs to locate the best deal. 相似文献

近十年来电力供应紧张一直困扰中国经济,大量文献检验了电力供应与经济增长的关系,而忽视了煤炭价格这一因素。基于1996年10月到2012年5月的月度数据,我们使用了包含煤炭价格的多变量方法进行分析。研究结果显示,Johansen协整检验发现电力供应、煤炭价格和经济增长之间存在长期均衡关系;拔靴Granger因果检验发现,电力供应单向引导经济增长,煤炭价格单向引起电力供应,煤炭价格与经济增长之间存在双向的Granger因果联系。据此,我们建议完善煤电价格联动机制,密切关注煤炭价格波动和打破电力市场行政垄断等。 相似文献

We examine the impact of the end of the coffee export quota system (EQS) on international‐to‐retail price transmission in France, Germany and the United States. We take account of the existence of long‐run threshold effects and short‐run price transmission asymmetries (PTAs). We find evidence of threshold effects in both periods (EQS and post‐EQS) in all three countries and the presence of short‐run PTAs during the post‐EQS period in all countries, but not during the EQS period. Our results indicate that the threshold values are smaller in the post‐EQS period, suggesting that retail prices became more responsive to changes in international prices. However, the speed of adjustment towards the long‐run equilibrium decreases during the post‐EQS period in the three countries. In the short run, non‐linear impulse response analyses indicate that a shock in international prices was more persistent during the EQS period than in the post‐EQS period. Moreover, we find evidence of short‐run PTAs in the post‐EQS period, with differences across countries. We find support for the ‘rockets and feathers’ principle in the United States; in contrast, retail prices respond faster when international prices are falling in Germany and France. We explain these differences in terms of market structures. 相似文献
