Assessing the Degree of Spot Market Integration for U.S. Natural Gas: Evidence from Daily Price Data 总被引:1,自引:0,他引:1
This paper assesses the degree of market integration in the U.S. natural gas market following the FERC’s ‘open access’ reforms.
Daily spot prices at 76 market locations from 1993 to 1997 are used to examine the geographic extent of the market and the
speed with which market forces move prices toward equilibrium in the face of ongoing price shocks. The empirical results suggest
that the East and Central regions form a highly integrated market, but that this market is quite segmented from the more loosely
integrated Western market. 相似文献

Some economists have argued that the close association between domestic saving and investment rates justify polices aimed at altering domestic saving flows so as to influence domestic investment flows. This interpretation assumes an endogenous investment response. Equally likely, theoretically, is that the close association is maintained by movements in saving. The present paper explicitly examines the endogeneity of the U.S. saving and investment flows. Overall the results suggest that while the domestic saving rate responds endogenously, the domestic investment rate does not. This finding may limit the potential benefits of saving policies. 相似文献

上市公司市盈率的微观影响因素分析 总被引:2,自引:0,他引:2
孙燕 《山东财政学院学报》2006,34(5):27-30
市盈率指标具有重要作用,影响我国上市公司市盈率的微观因素除了股利支付率、公司成长性和公司风险的一般因素外,还需要考虑流通股比重、盈利能力等。本文基于这样的考虑,利用面板数据对沪深2001~2004年A股上市公司数据进行了实证研究,分析表明各财务指标对市盈率的影响关系基本同假设一致,但有些关系不显著。意外地,净利润增长率与市盈率负相关,需要结合我国具体情况来认识市盈率,作出合理的解释。 相似文献

股票指数是投资者分析股市动态,拟定投资策略的重要参考依据,同时也是研究和分析一国政治、经济等情况的重要指标。在我国同时存在沪深两个证券交易所,人为地造成了股票市场的分割,难以形成统一的股票价格指数体系,应尽快编制出全国统一的股价指数,促进我国证券市场的健康发展。 相似文献

To examine the pricing behavior of suppliers of holiday goods and services, a margin approach, originally developed to explain price formation in service industries, has been applied to different sectors of the tourism industry, using Dutch data. The fundamental idea of the margin approach is that both cost and demand factors influence price formation. The specific market situation is supposed to determine the extent to which changes in cost factors can be passed on to consumers. Despite difficulties with the quality of data, the results can be characterized as promising. 相似文献

Following the predominance of macroeconomic stabilisation policies and passive income support schemes in the first phase of
transition, active labour market policies (ALMPs) have now come to play a more important role in transition economies. This
paper looks at the Polish experience and provides empirical evidence on the effectiveness of ALMPs. We use the Polish Labour
Force Survey of August 1994 in combination with its Supplement on the Evaluation of Labour Market Policies together with data
on ALMP expenditure at the regional (voivodship) level. The macroeconometric analysis of the relationship between labour market
flows and ALMP expenditure shows no significant effects. The microeconometric analysis reveals that ALMPs are not particularly
well targeted at the problem groups in the labour market. That is, women and people with basic vocational education do not
receive enough attention. As to the effectiveness of ALMPs, the paper shows that former participants cannot expect to find
employment more easily than their peers who have been unemployed but have not been in a programme. Subjective evaluations
of former participants also suggest that ALMPs, but especially works programmes, have not improved their chances to find a
job.
