This paper investigates the synchronization of Hong Kong's economic growth with mainland China and the US. We identify trends of economic growth based on the permanent income hypothesis. Specifically, we first confirm whether real consumption in Hong Kong and mainland China satisfies the permanent income hypothesis, at least in a weak form. We then identify the permanent and transitory components of income of each economy using a simple state-space model. We use structural vector autoregression models to analyze how permanent and transitory shocks originating from mainland China and the US affect the Hong Kong economy, and how such influences evolve over time. Our main findings suggest that transitory shocks from the US remain a major driving force behind Hong Kong's business cycle fluctuations. On the other hand, permanent shocks from mainland China have a larger impact on Hong Kong's trend growth.  相似文献

Using daily data on five sectoral indices from 2006 to 2014, this paper aims to investigate the possibility of fractional integration in sectoral returns (and their volatility measures) at Jordan's Amman stock exchange (ASE). Empirical analysis, using the log-periodogram (LP) and local whittle (LW) based semi-parametric fractional differencing techniques suggest that all sectoral returns at ASE exhibit short memory. However, in the case of volatility measures, we found evidence of long memory. Following the recent literature that argues that structural breaks in a time series could also explain the presence of long memory, we tested the volatility measures for the presence of structural breaks. We found that long memory in some volatility measures could be attributed to the presence of structural breaks. Furthermore, using impulse response functions (IRF) based on ARFIMA, we found that shocks to sectoral returns at ASE exhibit short run persistence, whereas shocks to volatility measures display long run persistence.  相似文献

This paper aims to analyse to what extent pupils value the characteristics of the state school foodservice and identify which variables affect the degree of pupils’ satisfaction with the quality of school meals. A representative sample of 33 state primary schools providing meals was extracted for the metropolitan city of Naples. Two questionnaires were distributed, one to the headteachers concerned and the other to 5th grade pupils (10–11 years old). Information about the catering companies was mainly sourced from the AIDA database. Pupil satisfaction was measured by two key variables: pleasantness of eating at school and food tastiness. Controlling for pupil, family, school, foodservice and catering company characteristics, the paper shows that the catering company size negatively impacts upon pupil satisfaction with the foodservice, whereas the estimated meal average production cost is positively associated with pupil satisfaction. The study could assist city boroughs in devising meal quality indicators to be taken into account in designing competitive tendering.  相似文献

Empirical research in accounting has lately focused much on sophisticated statistical methodology and econometrics and relatively less on conceptualization of the issues concerned. This essay is written to highlight the conceptualization of the issues as an important ingredient of empirical research in accounting. I present two methods of conceptualization – the single-entity approach and the game theoretic approach. I give several examples in accounting research to explain the conceptualization process. I hope that this essay will fill a much needed void in the research process in accounting and restore the balance between conceptualization and methodology.  相似文献

Studies done in developed economies have demonstrated a positive relationship between financial resource availability and CSR. Arguments that we term the Institutional Difference Hypothesis (IDH) drawn from the institutional literature, however, suggest that institutional differences between developed and developing economies are likely to result in different CSR implications. Integrating the logic of IDH with insights from slack resources theory, we argue that there exists a negative relationship between financial resource availability and CSR expenditures for firms in Ghana, a sub‐Saharan African emerging economy. We use lagged data from the Ghana Investment Promotion Centre and find that Return on Sales, Return on Equity, and Net Profitability were consistently associated with lower CSR expenditures. We highlight the implications of our findings for research and managers. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

构建柔性管理为核心的大学生管理新模式   总被引:2,自引:0,他引:2  
随着"以人为本"的教育管理理念的贯彻,以及当代大学生思想、行为、心理等的变化,传统以纪律约束为核心的刚性管理在一定程度上已不再适应高校学生管理的需求.构建柔性管理为核心的大学生管理新模式,符合社会发展的需要,能加强大学生的自我管理意识,有利于和谐校园文化的构建.  相似文献

目前制度变迁研究主要沿着两条主线展开:一是诺斯以意识为核心的非正式规则演化路线,二是林毅夫的国家规则构建路线,两条主线都忽略了意识演化与规则构建之间关系的研究。文章以农信社制度变迁为例,认为集体主义精神的农户抛弃以集体主义为基础的合作金融是一个集体主义悖论,而从农信社这一制度安排的变迁历史,及其所处的制度结构——农村经济体制的变迁历史中演化而来的社员集体主义恐惧意识,给该悖论提供了一个合理的解释。文章对集体主义恐惧意识进行深层分析后,提出国家规则构建与社员意识演化的互动周期假说。最后强调转轨国家在规则构建时,应充分重视社员意识的导向作用,并且提出了一些展望。  相似文献

We review developments in conducting inference for model parameters in the presence of intertemporal and cross‐sectional dependence with an emphasis on panel data applications. We review the use of heteroskedasticity and autocorrelation consistent (HAC) standard error estimators, which include the standard clustered and multiway clustered estimators, and discuss alternative sample‐splitting inference procedures, such as the Fama–Macbeth procedure, within this context. We outline pros and cons of the different procedures. We then illustrate the properties of the discussed procedures within a simulation experiment designed to mimic the type of firm‐level panel data that might be encountered in accounting and finance applications. Our conclusion, based on theoretical properties and simulation performance, is that sample‐splitting procedures with suitably chosen splits are the most likely to deliver robust inferential statements with approximately correct coverage properties in the types of large, heterogeneous panels many researchers are likely to face.  相似文献

《环境保护税法》的实施为检验“环保费改税”的效果提供了准自然实验。以2015—2020年沪深A股重污染行业上市公司为样本,采用双重差分模型(DID)检验了“环保费改税”对重污染企业全要素生产率的影响。研究结果表明:“环保费改税”显著提高了税费负担提标地区重污染企业的全要素生产率,整体上支持了“波特假说”;但是,税费负担提标地区重污染企业全要素生产率的提高并非源于“环保费改税”引发的创新补偿效应,而是源于“环保费改税”增加了资源配置效率。上述结果支持了“波特假说”有关“环境规制优化了资源配置效率进而提高企业生产率”的结论。进一步分析发现,“环保费改税”对税费负担提标地区重污染企业全要素生产率的提升效应在民营企业和研发投入强度大的企业中更显著。  相似文献

We examine the impact of COVID-19 pandemic crisis on the pricing efficiency and asymmetric multifractality of major asset classes (S&P500, US Treasury bond, US dollar index, Bitcoin, Brent oil, and gold) within a dynamic framework. Applying permutation entropy on intraday data that covers between April 30, 2019 and May 13, 2020, we show that efficiency of all sample asset classes is deteriorated with the outbreak, and in most cases this deterioration is significant. Results are found to be robust under different analysis schemes. Brent oil is the highest efficient market before and during crisis. The degree of efficiency is heterogeneous among all markets. The analysis by an asymmetric multifractal detrended fluctuation analysis (A-MF-DFA) approach shows evidence of asymmetric multifractality in all markets which rise with the scales. The inefficiency is higher during downward trends before the pandemic crisis as well as during COVID-19 except for gold and Bitcoin. Moreover, the pandemic intensifies the inefficiency of all markets except Bitcoin. Findings reveal increased opportunities for price predictions and abnormal returns gains during the COVID-19 outbreak.  相似文献
