PurposeThe purpose of this paper is to examine the pricing efficiency of the Malaysian crude palm oil (CPO) market before and after the structural break. This study uses the daily closing price of CPO and CPO futures (CPO-F) for the period ranging from June 2009 to August 2016 while taking structural breaks into account.Design/methodology/approachIn this study, symmetric and asymmetric long-run relationship model are employed, such as the Johansen cointegration, VECM, TAR and M-TAR models, to examine the impact of structural breaks on the pricing efficiency of the Malaysian CPO market.FindingsThis finding establish that Malaysian CPO price is efficient before and after the structural break. The consistent efficiency of the Malaysian CPO market supports the trading of the CPO-F in Globex and the use of Malaysian CPO pricing as the reference price. This study establishes that a structural break in the Malaysian CPO price series does not affect the pricing efficiency of the market.Research limitations/implicationsThis study shows that using Malaysian CPO price as a reference price is sustainable even in the event of a structural break. Therefore, market participants in the Malaysian CPO market have less to worry about the CPO price as it supports the weak form of efficiency. Price deviation in the short run may not lead to arbitrage profit as transaction cost may not be covered.Practical implicationsThis study implies that if there is distortion in the price due to shocks, both manufacturers and producers need to hedge their positions in the futures market (subject to their positions in the underlying market). By entering into the futures market, pricing is locked in advance; hence, price risk is eliminated. Such a distortion could also affect the efficiency of the CPO price, therefore this study also addresses the issue of efficiency of the local CPO market.Originality/valuePrevious studies on Malaysian CPO pricing efficiency did not take the effect of structural break into consideration, making it difficult for these studies to show consistency in the efficiency of the Malaysian CPO market.
目的本文的目的是检验马来西亚粗棕榈油(CPO)市场在结构性断裂前后的定价效率。本研究使用2009年6月至2016年8月期间的CPO和CPO期货(CPO- f)的每日收盘价,同时考虑了结构性突破。本研究采用Johansen协整、VECM、TAR和M-TAR等对称和非对称的长期关系模型,考察了结构性断裂对马来西亚CPO市场定价效率的影响。这一发现确立了马来西亚CPO价格在结构性断裂前后是有效的。马来西亚CPO市场的一致性效率支持了Globex中CPO- f的交易,并使用马来西亚CPO定价作为参考价格。本研究证实马来西亚CPO价格序列的结构性断裂并不影响市场的定价效率。研究局限/启示本研究表明,即使在结构性断裂的情况下,使用马来西亚CPO价格作为参考价格也是可持续的。因此,马来西亚CPO市场的市场参与者较少担心CPO价格,因为它支持弱形式的效率。短期内的价格偏差可能不会导致套利利润,因为交易成本可能无法覆盖。本研究表明,如果由于冲击导致价格扭曲,制造商和生产商都需要对冲其在期货市场的头寸(取决于其在标的市场的头寸)。通过进入期货市场,价格被提前锁定;因此,消除了价格风险。这种扭曲也会影响到CPO价格的效率,因此本研究也涉及到本地CPO市场的效率问题。原创性/价值以往对马来西亚CPO定价效率的研究没有考虑到结构性断裂的影响,使得这些研究很难显示出马来西亚CPO市场效率的一致性。

PurposeMagnet effect entails a hypothesis in market microstructure entailing a systemic likelihood of prices being sucked toward the theoretical threshold. The purpose of this paper is to investigate the existence of magnet effect in Bursa Malaysia via overnight returns.Design/methodology/approachThis study investigates the existence of magnet effect via overnight returns in Bursa Malaysia by utilizing historical daily price data from 1994 to 2017 by probabilistic regression approaches. The authors divide the study period into three distinct regimes based on regulatory limit mechanisms.FindingsBased on demarcated regimes, the authors find evidence of magnet effect in Bursa Malaysia throughout all regimes, with a heightened magnitude detected between 2002 and 2013. Moreover, upper limit scenarios exhibit a greater propensity for magnet effect. The authors end the paper with implications of the findings for portfolio managers, intraday traders, and policymakers.Originality/valueThe research is the first of its kind in attempting to measure the magnet effect in Malaysia via overnight jumps.
目的:磁铁效应包含了市场微观结构中的一个假设,即价格被吸向理论阈值的系统性可能性。本文的目的是通过隔夜回报来调查马来西亚证券交易所存在的磁体效应。设计/方法/方法本研究利用1994年至2017年的历史每日价格数据,通过概率回归方法,通过马来西亚证券交易所隔夜收益调查磁体效应的存在。作者根据监管限制机制将研究时期分为三个不同的时期。基于划分的制度,作者发现马来西亚交易所在所有制度中都存在磁体效应的证据,在2002年至2013年期间检测到磁体效应的强度增加。此外,上限情景表现出更大的磁体效应倾向。作者以研究结果对投资组合经理、日内交易者和政策制定者的启示结束了论文。这项研究是首次尝试通过隔夜跳跃来衡量马来西亚的磁铁效应。

PurposeConsidering the growing importance of finance in shaping corporate and human activities, the purpose of this paper is to focus on the United Nations Environment Programme (UNEP) Inquiry into the Design of a Sustainable Financial System that aims to align the financial system with sustainable development, with a focus on environmental aspects. Following the inquiry call for better disclosure approaches of material information on the “sustainability impacts” of the financial system as one of the areas of improvement to move toward a sustainable financial system, the author argues for a reform of the accounting model to better reflect the compliance of businesses with “quality of growth” imperatives.Design/methodology/approachThe paper rests on the entity theory of Littleton (1934).FindingsThe new accounting model requires creating a new equity capital account for the entity that is separate from the shareholders equity account. Valuation as well as other related issues on the functioning of this account is briefly explored in the paper. The reform also requires entrusting the responsibility of answering questions related to valuation, capital maintenance and income distribution to the board of directors that should be composed of representatives of the different capitals which have accrued, temporarily or indefinitely, to the business firm.Research limitations/implicationsThis paper calls researchers to explore the theoretical avenues proposed in the paper to develop the model in practice.Practical implicationsThe implementation of this reform requires a regulatory reform and the redesign of the economic coordination mechanisms which could be challenging in practice.Social implicationsThe accounting model proposed in the paper contributes to a new quality of growth, which is a growth based on well-being and inclusiveness.Originality/valueThe paper draws on the UNEP framework, which has not been investigated in other research studies.
考虑到金融在塑造企业和人类活动中的重要性日益增加,本文的目的是关注联合国环境规划署(UNEP)对可持续金融体系设计的调查,该体系旨在使金融体系与可持续发展保持一致,重点关注环境方面。在调查呼吁对金融体系的“可持续性影响”的重要信息进行更好的披露方法,作为向可持续金融体系迈进的改进领域之一之后,作者主张改革会计模型,以更好地反映企业对“增长质量”要求的遵守情况。设计/方法/方法本文以Littleton(1934)的实体理论为基础。新的会计模式要求为实体创建一个新的权益资本账户,该账户与股东权益账户分开。本文简要探讨了该账户的估值以及其他相关问题。改革还要求将回答与估值、资本维持和收入分配有关的问题的责任委托给董事会,董事会应由暂时或无限期累积到商业公司的不同资本的代表组成。研究局限/启示本文呼吁研究人员探索本文提出的理论途径,以在实践中发展模型。这一改革的实施需要进行监管改革和重新设计经济协调机制,这在实践中可能具有挑战性。社会意义本文提出的会计模型有助于实现一种新的增长质量,即基于福祉和包容性的增长。原创性/价值本文借鉴了环境署的框架,这一框架尚未在其他研究中进行调查。

Migration policy uncertainty and stock market investor sentiment 移民政策的不确定性和股市投资者情绪
Pub Date : 2018-10-30 DOI: 10.1108/JCMS-09-2018-0033

PurposeThe purpose of this paper is to examine the volatility transmission between migration policy uncertainty indices (MI) of France, Germany, UK and the USA, and respective stock markets of these countries. Therefore, the author’s major intention is to understand whether MI is a critical factor affecting company valuations and investor sentiment.Design/methodology/approachThe author proxies volatility via EGARCH (1,1) for all series and employs Diebold–Yilmaz (2012) methodology to test the spillover, which is a simple yet very intuitive procedure. This method allows one to analyze the numerical amount of spillover, as well as the direction.FindingsFindings propose that volatility transmission is from migration index to stock markets for the UK and US markets, but similar findings are not applicable for France and Germany. However, when cross-market transmissions are analyzed, it is observed that migration policy uncertainty of US spills significant volatility to all European stock markets. Hence, the findings underline the central role of US markets.Originality/valueGiven the increasing worries about migration across the USA and Europe, the author tries to cast light on whether investor sentiment alters by migration policies. The literature is recently building and best of the author’s knowledge; the paper is the first to investigate the cross-country spillover between MIs, which has not been performed before.
本文的目的是研究法国、德国、英国和美国的移民政策不确定性指数(MI)与这些国家的股票市场之间的波动传导。因此,作者的主要意图是了解MI是否是影响公司估值和投资者情绪的关键因素。设计/方法/方法作者通过EGARCH(1,1)对所有系列的波动率进行代理,并采用Diebold-Yilmaz(2012)方法来测试溢出效应,这是一个简单但非常直观的过程。这种方法允许人们分析溢出的数值量,以及方向。研究结果表明,对于英国和美国市场,波动率的传导是从移民指数到股票市场,但类似的发现并不适用于法国和德国。然而,当分析跨市场传导时,可以观察到美国移民政策的不确定性会对所有欧洲股市产生重大波动。因此,调查结果突显了美国市场的核心作用。原创性/价值鉴于美国和欧洲对移民的担忧日益增加,作者试图阐明投资者情绪是否会因移民政策而改变。文献是最近建立和最好的作者的知识;本文首次研究了MIs之间的跨国溢出效应,这在以前是没有的。

PurposeThe purpose of this paper is to study the efficiency of different oil and gas markets. Most previous studies examined the issue using low frequency date sampled at monthly, weekly, or daily frequencies. In this study, 30-minute intraday data are used to explore efficiency in energy markets.Design/methodology/approachSophisticated statistical analysis techniques such as Granger-causality regressions, augmented Dickey-Fuller tests, cointegration tests, vector autoregressions are used to explore the transmission of information between oil and gas energy markets.FindingsThis study provides evidence for efficiency in energy markets. The new information that arrives either to futures markets or spot markets is digested correctly, completely, and in a fast manner, and is propagated to the other market. The evidence indicates high efficiency.Originality/valueThis study is one of the first papers that uses 30-minute interval intraday data to investigate efficiency in oil and gas commodity markets.

PurposeThe purpose of this paper is to summarise and reflect upon key issues at the interface of prices, information and regulation with a focus upon the stock market in context. Reflecting upon academic research in the area of efficient markets, and regulatory policy, the concern is to discern issues in terms of policy and support for policy. What does the research imply for policy? Is it possible that the research, perhaps given its rhetoric, can be misinterpreted in relation to policy? The study is also concerned to develop avenues for future research based on these considerations.Design/methodology/approachThe paper is an analytical and critical review and writing.FindingsThe reading of the research suggests a pragmatic regulatory policy that should be concerned to improve stock market functioning, including with respect to information, as well as the context of which this is part. At the same time, the literature may be read as promoting anti-regulatory policy.Practical implicationsOn the one hand, these are consistent with the pragmatic policy referred to above. On the other hand, further research is suggested to explore substantively the rhetoric of the research and its interpretation and to explore understandings of the research and its implications amongst key constituencies in practice.Originality/valueThe concern is to bring key insights from the academic literature together with a view to promoting a pragmatic policy orientation, while cautioning in a critical perspective about how this academic literature and research might be interpreted from a policy perspective.
本文的目的是总结和反思在价格、信息和监管的界面上的关键问题,并以股票市场为重点。反思有效市场和监管政策领域的学术研究,关注的是在政策和政策支持方面辨别问题。这项研究对政策意味着什么?考虑到这项研究的措辞,是否有可能在政策方面被误解?本研究也关注在这些考虑的基础上为未来的研究开辟途径。设计/方法/方法这篇论文是一篇分析性和批判性的评论和写作。对研究的解读表明,应该关注一种务实的监管政策,以改善股票市场的功能,包括信息,以及它所处的环境。与此同时,这些文献可能被解读为提倡反监管政策。一方面,这些与上面提到的实用主义政策是一致的。另一方面,建议进一步研究,以实质性地探索研究的修辞及其解释,并探索研究的理解及其在实践中的重要意义。原创性/价值我们关注的是将学术文献中的关键见解结合在一起,以期促进务实的政策导向,同时以批判的角度警告如何从政策角度解释这些学术文献和研究。

PurposeThe purpose of this paper is to assess the financial performance of the intermediary institutions that have operated in the Turkish capital markets taking the issue of bank-origin and non-bank-origin institutions into account.Design/methodology/approachFinancial performance of the intermediary institutions has been measured by the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method between the years 2005 and 2016. In order to implement the TOPSIS method, the relative importance of financial performance indicators has been determined by Entropy, survey results and considering equal weights approaches.FindingsEmpirical findings indicate that the average performances of continuously operating intermediary institutions during the concerned period are above the average performance levels of all intermediaries. Additionally, the average rank of bank-origin intermediary institutions have been found higher than the non-bank origins for all years. This reveals that the average financial performance of the bank-origin intermediary institutions is higher than the average score of non-bank origins during the related years.Originality/valueThis study is unique in terms of evaluating the performance of intermediary institutions in Turkish capital markets with a comprehensive framework. Determining the relative importance of financial performance indicators according to entropy, survey results and equal-weight approaches and revealing the average financial performance ranking methodology for bank-origin and non-bank-origin intermediary institutions have added value.
本文的目的是评估在土耳其资本市场上运营的中介机构的财务绩效,同时考虑到银行和非银行机构的问题。2005年至2016年间,中介机构的财务绩效通过理想解决方案相似性排序偏好技术(TOPSIS)方法进行了衡量。为了实施TOPSIS方法,通过熵、调查结果和考虑等权方法来确定财务绩效指标的相对重要性。实证结果表明,持续经营中介机构在相关时期的平均绩效高于所有中介机构的平均绩效水平。此外,银行来源的中介机构的平均排名一直高于非银行来源的中介机构。这表明,在相关年份,银行源中介机构的平均财务绩效高于非银行源中介机构的平均得分。原创性/价值本研究在综合框架下评估土耳其资本市场中介机构的绩效方面是独一无二的。利用熵值法、调查结果法和等权重法确定财务绩效指标的相对重要性,揭示银行类和非银行类中介机构的平均财务绩效排名方法具有附加价值。
