股票价格均值回归理论研究综述

随机漫步理论认为股票的价格是不能预测的,许多实证检验的结果也支持了这一结论。但是,近年来均值回归理论对随机漫步理论提出了挑战。从长期来看,股票价格呈均值回归是必然的;均值回归具有不对称性;政府行为对股票的均值回归具有一定的影响。     

现代审计活动中的行为研究

审计作为一种独立的经济监督活动,具体表现为审计人员个体与群体组织的一系列有序的行为,而审计行为与其它行为一样,需要进行科学与合理的规划、领导、组织和控制。因此,在现代审计活动中,必须注重对审计行为的研究,把握个体行为、群体行为两者的内在联系和相互作用,充分调动审计人员的工作积极性和主观能动性,增加审计群体的凝聚力,促进审计组织活动的有效进行。     

论采油企业成本管理控制长效机制的建立

为了完成生产经营任务，采油企业内某些单位客观上还存在一些短期行为。从最终影响来看，采取短期行为，可能使得采油成本在短期内趋于下降，但会导致后期成本急剧上升，不利于企业的可持续发展。因此，需要运用法律、行政、制度、政策等多种手段，建立成本管理控制长效机制，以克服各种短期行为的发生，从而实现采油企业成本的长期效能。     

美国反垄断的经济学思考

众所周知,国际上垄断的主要形式是托拉斯,而美国这个崇尚自由竞争的经济大国,其垄断行为更为普遍。美国反垄断法的出台及实施,引起了我们更多的经济学思考,研究借鉴美国反垄断法的构成体系、主要内容以及典型的实施案例,对我国反垄断理论的研究和实践将有所裨益。     

机构投资者与个人投资者非理性行为差异研究

机构投资者与个人投资者是证券市场的重要组成部分,其非理性程度直接影响着市场的健康稳定。本文基于有情境元素的问卷调查,构建包含投资者类别为自变量,年龄和性别为控制变量,16种常见非理性行为为因变量的分析框架,实证检验机构投资者与个人投资者非理性行为差异。结果表明,中国机构投资者与个人投资者都存在严重的非理性行为;相比机构投资者,个人投资者非理性程度更为严重;机构投资者与个人投资者在偏好逆转、证实性偏差、沉没成本、模糊厌恶、处置效应和损失厌恶方面存在显著差异。本研究为投资者防范非理性行为提供建议,为市场稳定发展提供参考。     

Is unemployment good for the environment?

Environmental quality is a public good, potentially impacted by everybody. Individual level pro-environmental behavior affects environmental quality in the aggregate. Therefore, it is important to understand what causes individual’s pro-environmental behaviors to change. We quantify the causal effect of one determinant, unemployment, using an EU-27 population representative Eurobarometer survey. Drawing on results from the theory of the private provision of public goods, and recognizing that unemployment decreases income and the opportunity cost of time, we formulate testable predictions that unemployment will decrease the extent of pro-environmental behaviors that require monetary contributions and increase the extent of pro-environmental behaviors that mainly require time/effort. Instrumental variables regressions provide empirical evidence to support these hypotheses. Changes in the unemployment rate within a sub-national region provide the exogenous variation needed to identify the causal effect. Several supplemental questions on the survey provide evidence that environmental issues lose saliency and economic issues gain saliency when one becomes unemployed, suggesting that interested parties may wish to emphasize cost savings of pro-environmental behavior rather than environmental benefits during times of increased unemployment.

Subsidiary managers’ knowledge mobilizations: Unpacking emergent knowledge flows

Knowledge flows are a key source of advantage for multinational corporations (MNCs); however the nuances of knowledge flow practices and their micro-foundations require further theoretical development. Using qualitative data on 40 cases of subsidiary managers’ knowledge mobilizations, this paper unravels micro-level practices of knowledge flows in MNCs. We find that subsidiary managers’ knowledge mobilizations initiate a complex pattern of subsidiary knowledge inflows, pinpointing the significance of lateral and bottom up exchanges (locally as well as internationally). We use these insights to distinguish between two types of subsidiary knowledge flows: deliberate and emergent, and discuss how their differences have profound implications for the investigation of MNC knowledge flows and their micro-foundations.     

Compulsory versus voluntary voting: An experimental study

We report on an experiment comparing compulsory and voluntary voting institutions in a voting game with common preferences. Rational choice theory predicts sharp differences in voter behavior between these two institutions. If voting is compulsory, then voters may find it rational to vote insincerely, i.e., against their private information. If voting is voluntary so that abstention is allowed, then sincere voting in accordance with a voter's private information is always rational while participation may become strategic. We find strong support for these theoretical predictions in our experimental data. Moreover, voters adapt their decisions to the voting institution in place in such a way as to make the group decision accuracy differences between the two voting institutions negligible. The latter finding may serve to rationalize the co-existence of compulsory and voluntary voting institutions in nature.     

Effects of Label on Consumer Preferences: Focus on Hawaiian Avocado Industry

This study examines market challenges facing a local agriculture industry in a small island setting. Examination of the Hawai‘i local avocado industry indicates labeling can address the product information gap between consumers and producers, improve market share, and increase import substitution by local products. Currently, local avocados occupy only 33% of market share, compared with 67% captured by imports. Consumer preferences among local labeled, local unlabeled, and imported avocados were analyzed using multinomial logistic regression. Statistical results showed that labels influence consumers’ decisions to buy local or imported avocados, and their preferences were also influenced by sociodemographic variables, avocado characteristics, and purchasing behavior. Key market segments to target and policy implications are also discussed.
