Replication with MTurk of the experimental design by Gangadharan,Grossman, Jones & Leister (2018): Charitable giving across donor types

Understanding the motivations behind charitable giving and the identification of donor types have aroused growing interest among researchers. The economic literature has highlighted the model of pure altruist and subsequently the more realistic model of impure altruist or warm-glow giver. The need to distinguish and empirically identify these types of donors has given rise to some economic experiments. This paper - using the platform by Amazon's Mechanical Turk with a large sample of participants (N = 1062) - shows the findings of a near replication of the experimental design by Gangadharan et al. (2018). Results are consistent with the original study and confirm the validity of the procedure and the ability to replicate a critical feature of the original design.     

Sources of information and portfolio allocation

This research investigates the relationship between how a household receives financial information and the degree to which investment portfolios are diversified. Diversification is measured as allocation across asset classes and share of assets held in each asset class. Propensity score-based techniques incorporating stratification and weighting are employed to better isolate causal links, while also controlling for objective and subjective financial literacy and overconfidence. Results indicate that the use of financial planners and brokers is associated with an increase in asset class diversification. Households that consult with financial planners and bankers allocate their wealth systematically different from those who do not. These results highlight the role that financial professionals play in helping households make investment decisions.     

IMAGE AND MISREPORTING

In this paper we analyze how image utility can lead to misreporting of private information in contexts where truthful reports maximize monetary outcomes. In a controlled experiment, subjects go through a series of quiz questions and subsequently report a performance measure. We vary whether reports are made to an audience or not. In an additional feedback treatment, reports are also stated to an audience and afterwards the experimenter publicly verifies whether reports were correct. We find that in the audience treatment, stated reports are significantly higher relative to the private treatment as well as the feedback treatment. Our findings suggest that overconfident appearance might be a consequence of social approval seeking.     

Walking the talk in multiparty bargaining: An experimental investigation

We study the framing effects of communication on payoffs in multiparty bargaining. Communication has been shown to be more truthful and revealing than predicted in equilibrium. Because talk is preference-revealing, it may effectively frame bargaining around a logic of fairness or competition, moving parties on a path toward or away from equal-division agreements. These endogenous framing effects may outweigh any overall social utility effects due to the mere presence of communication. In two studies, we find that non-binding talk about fairness within a three-party, complete-information game leads toward off-equilibrium, equal division payoffs, while non-binding talk focusing on Competitive Reasoning moves parties away from equal divisions. Our two studies allow us to demonstrate that manipulated pre-game talk and spontaneous within-game dialogue lead to the same results.     

区域物流需求分析——以长江三角洲南通地区为例

本论文基于一个二维分析体系——以物流需求的主要主体为基准轴，以物流各环节的指标为参变轴，以定性与定量相结合的方法，对长江三角洲的南通地区的物流需求进行分析和预测；提出大中城市在进行物流需求分析时，必须基于所处地理区位和经济区位，以及应从长远考虑的可持续发展分析思想。

基于信息熵的物流规划实证分析

本文采用信息熵不确定性评价方法对某物流园区规划进行了实证分析。经过实证分析表明,该物流规划方案的基础物流设施收益较低,但必须投资建设,汽车检测中心、信息中心能够带来较高的增值收益。本文还对比采用了投资收益分析,其结论与信息熵评价方法一致。
