平台型网络市场的虚拟性与隐蔽性导致商家隐瞒、欺骗消费者的行为愈演愈烈,衍生了新的治理难题。基于交易成本理论和社会交换理论,立足平台主动治理视角,文章探索平台主动治理中的事前商家规范机制、事中交易保障机制和事后争议处理机制对商家强、弱投机行为的影响,以及平台声誉对其影响的调节作用。基于消费者视角开展问卷调查,对数据进行结构方程模型分析和分层回归分析,结果表明:弱投机行为对强投机行为具有显著正向影响;商家规范机制和争议处理机制对强、弱投机行为均具有抑制作用;而交易保障机制对弱投机行为具有促进作用;平台声誉对交易保障机制、争议处理机制和弱投机行为之间的关系具有负向调节作用。 相似文献

以江西省宜春市"月都花溪谷"乡村森林旅游项目规划中哲学元素的应用为个案,结合哲学理论进行分析。结果表明:乡村森林旅游项目规划应有哲学的自觉,根据项目所在地自然和人文资源禀赋,因地制宜地吸收哲学元素,从而打破乡村森林旅游项目同质化和见物不见人的困局,赋予乡村森林旅游项目以特色和灵魂。因此,提出突破森林旅游项目规划中一元化的经济思维定势、以哲学思维唤起人学意义、因地制宜激发内生式哲学文化活性等启发性建议。 相似文献

This paper examines the behavior of futures prices and trader positions around the occurrence of price limits in commodity futures markets. We ask whether limit events are the result of shocks to fundamental volatility or the result of temporary volatility induced by the trading of noncommercial market participants (speculators). We find little evidence that limits events are the result of speculative activity, but instead associated with shocks to fundamentals that lead to persistent price changes. When futures trading halts price discovery migrates to options markets, but option prices provide a biased estimate of subsequent future prices when trading resumes. 相似文献

This historical review traces the development of postponement research starting in the fifties. The focus is on seven related themes: connecting form and time postponement, conceptual extensions to postponement, decoupling points, design for postponement, customization and mass customization, factors favoring postponement implementation, and postponement in global settings. Within these themes, the review includes concepts such as postponement costs, decoupling points, part commonality, and the impact of demand correlations on the benefits of postponement. The review suggests that substantial progress has been made in postponement research. 相似文献

The authors study abnormal returns and volume in the days surrounding takeover speculation by financial media. Significantly positive price and volume responses 2 days after publication are observed. While most of this effect dissipates shortly thereafter, some excess returns remain impounded into the stock price. A study of the ex post takeover probabilities suggests that a positive response is justified, as takeover probabilities for such firms subsequently increase. This evidence is consistent with the idea that financial media speculation can facilitate the release of useful private information to shareholders. However, significantly positive excess returns and volume in the few days before publication also suggests that certain shareholders may benefit disproportionately. 相似文献

This paper estimates the revenue potential of a financial transaction tax (FTT) for US financial markets. We focus on analyzing the revenue potential of the Inclusive Prosperity Act that was introduced in the US House of Representatives in 2012 and the US Senate in 2015. The tax rates stipulated in this Act include 0.5% (50 basis points (bps)) for all stock transactions, 0.1% (10 bps) for all bond transactions and 0.005% (0.5 bps) on the notional value of all derivative trades. We examine three sets of evidence to generate potential revenue estimates: 1) the levels of transaction costs in US financial markets over time and within the range of financial market segments; 2) the extent of trading elasticities under various trading conditions; and 3) the current level of trading activity in US financial markets. Based on this evidence, we conclude that a US FTT operating at the tax rates stated above would generate about $220 billion per year, equal to about 1.2% of the current US GDP. 相似文献

The trading behaviour of institutional investors has attracted much attention. However, many issues related to their trading behaviour cannot be addressed without high‐frequency changes in institutional ownership. Based on a measure of the trading behaviour of institutional investors by using an institutional account dataset from China, we find that (i) active institutions trade speculatively by taking advantage of individual investors; (ii) individuals buying high and selling low offer liquidity only on average; (iii) foreign investors do not show significant patterns in speculation; and (iv) trading of active institutions significantly affects price. This study casts doubt on the conventional wisdom that institutional or sophisticated investors improve market efficiency by correcting mispricing, and provides direct evidence for institutional investors' speculation behaviour and their destabilising effect on the stock market. Results suggest that regulators in emerging markets should monitor institutions' speculation to bring fairness and justice to the stock market. 相似文献

国家审计是国家治理的基石与保障,国家审计体现了国家政治意志,国家政治、经济和文化的发展又调整着国家审计的功能和边界。基于多学科视角探讨国家治理与国家审计的协同关系,揭示国家审计的哲学本质与政治功能,理清国家审计的经济边界,分析国家审计的法治建设与文化建构等基本问题,构建国家审计基础理论的分析框架,认为国家审计可以通过提升组织的设计与管理、政治制度的设计、合法化的基础及文化与社会等要素来改进国家治理。 相似文献
