Do rice prices follow a random walk? Evidence from Markov switching unit root tests for Asian markets 下载免费PDF全文
This study revisits the issue of mean reversion in the import rice prices of six Asian countries over the period between 1995 and 2015. Augmented Dickey Fuller tests with a conventional linear regression model support the presence of a unit root in the levels of the price data. However, when regressions allow for Markov switching in coefficients and variances to capture periodic shifts in levels and volatilities, there is strong evidence against the unit‐root null hypothesis in favor of stationarity over much of the observation period. 相似文献

在现有研究成果的基础上,首先提出经济型宾馆行业顾客忠诚驱动综合理论模型,然后利用通过实证调研收集的样本数据,运用AMOS软件建立了顾客忠诚驱动的结构模型,并对模型进行检验。检验结果表明:顾客价值、服务因素、转移成本、顾客满意感、顾客信任感和顾客归属感是经济型宾馆顾客忠诚的决定因素;顾客价值、服务和转移成本直接影响顾客的行为性忠诚,顾客满意感、顾客信任感和顾客归属感直接影响顾客的态度性忠诚等。最后指出本研究在理论与实践上的意义。 相似文献

This study analyzes the impact of bank relationships on a firm's borrowing costs. We find that a firm's borrowing costs decrease with relationship strength, proxied by the share of bank debt provided by the lender. Borrowing costs, however, rise with relationship length. While the increase over time is weak on average, bank‐dependent borrowers face a substantial premium after several relationship years. Switching the lender initially leads to only a small price discount on average. However, the discount is considerable for borrowers that switch and had a strong relationship with their previous lender. Our results suggest that close lending relationships lead to benefits for the firm, but may also imply hold‐up costs in the long term. 相似文献

Most environmental economists argue that direct experience with the good being valuated, or with similar goods, is a precondition for providing valid willingness to pay (WTP) responses to contingent valuation questions. Two questions are posed in this article. The first is whether previous use experience of a resource (Séné nature reserve) similar to that being valuated (future nature reserves) and located in the same geographical area (Gulf of Morbihan) impacts on WTP. The second is whether accounting for the endogeneity of direct experience matters in the estimation of WTP. We find that respondents who have not experienced the Séné nature reserve provide value estimates that are statistically comparable to that of respondents who have experienced it. Our assumption is that respondents have acquired sufficient and adequate experience of future nature reserves from the questionnaire that experience obtained by experiencing the Séné nature reserve was not necessary for making a valid value formulation. Hence, aggregation of WTP estimates to obtain a total valuation of the future nature reserves is reasonable over the full target population. In addition, our results show that direct experience is endogenously determined; but controlling for the endogeneity has a marginal effect on WTP estimates. 相似文献

随着中国资本项目开放进程的推进,跨境证券投资对国内金融市场的冲击日益增强。在此背景下,本文首先通过构建考虑了资本市场收益率以及有管理浮动汇率制度的IS LM BP模型对跨境证券投资与中国国内金融市场的相互影响机理进行了理论探究,并基于中国2005年7月—2016年8月的月度数据,运用马尔科夫区制转移向量自回归模型对中国资本账户开放进程中跨境证券投资与人民币汇率、股票市场收益率、短期利率的联动关系进行了实证分析。研究结果表明:第一,四者的关联性存在明显的区制特征,区制1主要包括次贷危机时期(2007—2008年)、欧债危机时期(2010—2012年)以及后金融危机时期(2015—2016年),经济呈现“股票市场收益率较低、跨境证券投资较少、短期利率较高、金融市场波动性大”的状态;区制2主要包括次贷危机前夕(2005—2006年)、次贷危机后的量化宽松时期(2009—2010年)以及欧债危机后的调整期(2013—2014年),经济呈现“股票市场收益率较高、跨境证券投资较多、短期利率较低、金融市场波动性小”的状态。第二,当处于资本市场化进程较快、金融市场波动性较大的区制阶段(区制1)时,跨境证券投资与国内金融市场的联动关系更加明显。本文研究结论对于我国进一步开放资本市场具有借鉴价值和政策启示。 相似文献

Summary. The purpose of this paper is to consider environmental taxation which would control emissions of firms in a model of growth
cycles. In the model presented below, the economy may experience two phases of growth and environmental quality: “the no-innovation
growth regime” and “the innovation-led growth regime”. Aggregate capital and environmental quality remain constant in the
no-innovation growth regime, while they perpetually increase in the innovation-led growth regime. The paper shows that the
tax plays a key role in determining whether the economy stably converges to one of the two regimes or fluctuates permanently
between them. It also shows that there is a critical level of the tax and that the economy obtains higher growth rates of
capital and environmental quality by raising (or reducing) the tax if the initial tax is below (or above) the critical level.

The study examines Nigeria's business cycles between October 1998 and October 2017 and ascertains the importance of general elections cycles in engendering cyclical fluctuations in different measures of business cycles. A framework based on political business cycles theory was estimated with a dynamic Markov‐switching regression technique. The study finds that election cycles are adequate in predicting cycles in food prices, non‐farm prices, exports, and imports in Nigeria while a significant effect of election cycles on the stock market, general price level, and exchange rate could not be established. The study concludes that cycles in food, non‐farm prices, imports, and exports can be predicted by future general elections while re‐election seeking behaviour of politicians lacks the power to influence stock market performance and exchange rate in Nigeria. Hence, artificial business cycles that result primarily from politicians manipulating certain fiscal tools targeted at stimulating the economy only to increase the re‐election chances could be minimized if monetary and fiscal institutions are strong, effective, and truly independent. This will ensure that policies are not manipulated between elections by politicians but are well targeted at achieving a set of long‐term developmental goals. 相似文献

This paper studies the impact of output growth on output growth uncertainty by considering two important issues hitherto not properly and adequately addressed to in the existing empirical studies specifying this relationship. These are: (i) the possible existence of a threshold level of output growth, and the consequent identification of two regimes characterized by high and low output growth, and (ii) whether or not the coefficient capturing the causal link is different in these two output growth states. This paper proposes a regime switching model to study this asymmetric effect for 16 OECD countries. Based on monthly time‐series observations, our results strongly support that the impact varies significantly between the two output growth regimes with the coefficient in the high growth regime being negative for majority of the countries. 相似文献
