This paper proposes a multivariate distance nonlinear causality test (MDNC) using the partial distance correlation in a time series framework. Partial distance correlation as an extension of the Brownian distance correlation calculates the distance correlation between random vectors X and Y controlling for a random vector Z. Our test can detect nonlinear lagged relationships between time series, and when integrated with machine learning methods it can improve the forecasting power. We apply our method as a feature selection procedure and combine it with the support vector machine and random forests algorithms to study the forecast of the main energy financial time series (oil, coal, and natural gas futures). It shows substantial improvement in forecasting the fuel energy time series in comparison to the classical Granger causality method in time series. 相似文献

This study examines the reliance on trust as a heuristic by individuals when making personal financial decisions, using a qualitative case study. We show that in the face of complexity and choice, individual investors predominantly resorted to the heuristic of trust to make financial decisions. This demonstrates the need for industry and public policy‐makers to be aware that individuals can and will resort to simplified heuristics as a basis for financial decision‐making, particularly within an environment where substantial complexity and choice exist. 相似文献

In prior studies, accounting and decentralization corruption solutions have so far been analysed in isolation. In this article, we connect these two strands of literature on corruption. Understanding this connection is important because weak financial accounting and reporting systems can inhibit monitoring incentives and thus reduce decentralization benefits in countering corruption. We argue that the effectiveness of decentralization as an anti-corruption barrier is complemented by the quality of the accounting practice in a country. Using multiple sources of data, we find that decentralization has a positive and increasing effect on reducing corruption among countries with a high-quality accounting practice. In contrast, decentralization has a negative and decreasing effect on reducing corruption among countries with weak-quality accounting practices. These findings are robust to alternative measures of accounting, decentralization and corruption and to endogeneity tests. Our findings demonstrate the crucial information role of accounting in enhancing decentralization monitoring mechanisms and in thereby reducing corruption. 相似文献

ABSTRACTThis study responds to recent calls in the literature to examine fraud using detailed case studies, extending knowledge beyond individual incentives and capital market reactions towards a more contextualized understanding of the concept. We use an institutional logics perspective to challenge existing assumptions about a universally valid meaning of compliance, fraud, and faithful representation. Presenting the case of the Swedish bank HQ, we show how the interpretation of the accounting standard for option measurement varies across different enforcement bodies because the meaning of compliance is socially negotiated across the institutional logics of markets, financial regulation, and law. The independent decision-making of the different enforcement bodies leads to a systematic variation in the interpretation of principles-based accounting standards without ultimate coordination. To define consistent boundaries of compliance across institutional logics, and thus, to distinguish between fraud and allowable managerial discretion becomes problematic. Faithful representation, in turn, cannot be understood as financial statements reflecting a correct value or as financial statements being prepared in accordance with acceptable practice, as suggested in the earlier literature. Instead, faithful representation itself becomes a contextually bound concept, which can only be defined within an institutional logic. 相似文献

本文首先采用马尔科夫区制转移模型测算金融周期和12类行业的技术投入周期,进而采用交叉谱分析法和OLS法分析金融周期对行业技术周期的影响,结果发现:不同金融变量的周期具有异步性,各行业的技术投入周期具有明显差别;不同金融变量周期与行业技术投入周期之间存在不同的数量关联性,对不同的行业技术投入具有不同的影响作用;在繁荣阶段,金融市场和银行对各行业的技术投入都具有正向推动作用,但金融市场对高密度创新行业技术投入的推动作用更为显著,银行对低密度稳定行业技术投入的推动作用更为显著;在紧缩阶段,金融市场对高密度创新行业技术投入的紧缩效应更为剧烈,银行却对低密度稳定行业的技术投资下行起到缓解作用。根据这些事实和规律,可以引导利用各金融变量对具有发展前景的行业强化技术投资助推作用,提升经济结构优化效率。 相似文献

产业集聚和市场集中是影响区域创新能力的重要因素。本文考察了京津冀、长三角两大经济圈制造业产业集聚与市场集中对区域技术创新能力的作用。实证分析结果表明:两大经济圈制造业集聚与市场集中均在一定程度上促进了区域创新能力的提升,但由于两大区域体制机制条件、创新环境、产业组织形态等不同,制造业产业集聚影响区域技术创新的程度、特征与路径也存在一定差别。两大经济圈应采取差异化集群发展方式,加快推进制造业集群升级,特别是应抢抓第四次工业革命发展机遇,提升制造业智能化水平,提升区域创新能力水平。 相似文献

依据城镇化发展过程中要素空间集聚理论,展开区域经济发展的空间经济结构研究。通过城市引力、克鲁格曼指数计算,比较分析城镇群内部城市吸引力和城市产业分布的差异性,通过人口与生产空间分布集中度指标和不一致系数的测算,分析了山西省城镇群空间要素集聚效应。研究表明,山西省的城镇群规划与要素空间集聚趋势整体一致,城市间产业分工体系基本形成,城镇群的要素集聚效应明显,但人口与生产分布仍存在不一致性。研究认为,山西省城镇群发展应该继续明确各城市的产业分工和特色,引导劳动力和资本要素的合理流动,实现人口与生产空间分布的一致。 相似文献

This study investigates the effect of cultural distance on global bank linkages using country-pair data for the period 1990–2013. We followed Schwartz (2006) to measure cultural distance, and employed the number of bank pairs involved in cross-border syndicated lending from the source to target countries as a measure of bank linkages. We found that cultural distance has a negative association with bank linkages. This effect is stronger in countries featuring higher informational asymmetries, as represented by weaker institutions, higher uncertainty, or revolution shocks. Our results hold even when employing alternative measures of bank linkages and cultural distance, and when considering the potential endogeneity of cultural distance. 相似文献

The global financial crisis since 2008 revived the debate on whether or not and to what extent financial development contributes to economic growth. This paper reviews different theoretical schools of thought and empirical findings on this nexus, building on which we aim to develop a unified, microfounded model in a small open economy setting to accommodate various theoretical possibilities and empirical observations. The model is then calibrated to match some well-documented stylized facts. Numerical simulations show that, in the long run, the welfare-maximizing level of financial develop is lower than the growth-maximizing level. In the short run, the price channel (through world interest rate) dominates the quantity-channel (through financial productivity), suggesting a vital role of international cooperation in tackling systemic risk of the global financial system. 相似文献
