The effect of environmental information on investment allocation decisions – an experimental study
通过实验让金融专业学生基于财务和环境信息分配投资，发现定性环境信息影响短期决策，具有类似财务信息的风险降低潜力，而定量信息会削弱这种影响。
Abstract This paper focuses on the use of environmental information in investment decision making. The research approach employed is based on an experiment where three groups of final year finance students were asked to allocate investment funds between two companies based on financial accounts and information material from these companies in which environmental information was included in varying degrees. The overall conclusion is that the qualitative environmental information affects short term allocation decisions, hence indicating a risk reduction potential of environmental information comparable to the classic interpretation of financial information. The quantitative environmental information included in the experiment seems to mitigate rather than extend the directional effect of more environmental information. The evidence also seems to indicate that decision makers are not always aware which information categories affect their decision making. Hence, this has implications for how the potential value of environmental information is to be assessed. Finally, experimental studies as a methodology seem to be better suited to indicate actual effects of different types of information on decision making than attitude surveys.
