Implicit attitudes toward risk: the construction and validation of the measurement method

Methods that are typically used to examine individual differences in risk attitudes (e.g. lotteries, dilemmas, questionnaires) require participants to explicitly declare their willingness to take risk. Therefore, they may be biased by the need for self-presentation or situational characteristics such as time pressure and cognitive constraints that lead to more spontaneous and automatic processing of risk-related information. The aim of this study was to construct an indirect measure of risk attitudes that is free of these methodological limitations. The method based on the Implicit Association Test shows high internal reliability and satisfactory stability over time. It correlates moderately with different explicit measures of risk attitudes that are related to sensation seeking. Finally, it is characterized by a high predictive power. Adding the implicit measure to the set of independent variables representing declarative evaluations of risk attitudes significantly improved the model predicting risky real-life behavior. We argue that the indirect assessment of risk attitudes presented in this paper may be used as an universal measure of people’s risk propensity that is free of biases related to self-presentation and situational factors.     

Multiple bank regulators and risk taking

The potential for banks to arbitrage between regulators exists both in the US, with its multiple federal banking regulators, and in Europe, due to multinational banking. This paper models multiple regulators that have an agency bias, which can give rise to a “race to the bottom”. The model is used to analyze the interaction between the regulatory equilibrium and several salient pre-crisis features: rising bank leverage; wholesale funding with asymmetric information; and increasing supervisional costs to disentangling bank asset exposures. Each of these raises bank risk taking on its own, but regulatory competition is shown to be an amplification mechanism.     

Motivations of volunteer overseas and what have we learned – The experience of Taiwanese students

The study explores motives for Taiwanese students to volunteer overseas and what they have learned from the trip. Their motivations are classified into pull and push factors. Pull factors include expecting challenge, validating personal perceptions of the place, and getting to know local residents and experiencing the life in a foreign culture. Push factors identified as underlying themes include escaping from daily life to reorganize and relax, look for new ways of life and self exploration, a desire to give back, to make friends who share a common interest, a less expensive way of traveling, encouragement by others, and parental compulsion. The students gain several benefits from this trip, including a better attitude to learning, better communication skills, better stress management, an appreciation of what they have, being more active, becoming more generous and developing empathetic skills, be willing to hear and respect different voices, having trust in co-workers and be willing to admit deficiencies, appreciating a slower life pace, having an open mind, and learning to control material desire.     

Intermarket efficiency: An application of interbattery APT to mortgage-backed securities

Increasing popularity of investments in mortgage-backed securities has led to closer integration of the mortgage market into traditional capital markets. Using monthly returns during 1982–1988 for common stocks, Treasury bonds and GNMA and FHLMC mortgage-backed securities, the interbattery factor analytic Arbitrage Pricing Theory of (Cho, 1984) is used to test five hypotheses for intramarket and intermarket integration. Results indicate that three to five common factors are found within the same security market, while only one to three factors are found common between different markets.The APT could not be rejected within the same security market, but was rejected in most intermarket comparisons. While risk-free rates are found to differ between markets, the risk premium tests are conclusive indicators of integration. Our results support claims that the stock, bond, and the mortgage-backed securities markets are integrated.     

消费者群体隐性需求濡染扩散模式研究

在进行营销模式的本土化创新以及开创新的市场空间时，关注创新采用的隐性需求及其在关联需求网络中的扩散机制，对于洞察消费者隐性需求的层次，细分消费者的群体特征以及进行产品和市场创新均具有重要意义。     

资产配置策略与基金系QDII收益分析

本文从前十大重仓股占比、股票集中度、行业集中度、投资区域集中度、夏普指数等指标研究基金系QDII资产配置策略与其收益的关系。统计数据结果表明,过于集中的资产配置对QDII基金收益产生了负效应。同时,QDII基金在成立时机选择、资产配置和外汇投资战略上都欠妥当。由此可见,对于QDII产品而言,资产组合的构建需要符合分散国内系统性风险的原则,否则不会使QDII这种外汇投资基金具有特殊的优势。     

创业型领导对追随者创造力的影响

采用201位领导者-追随者调研数据,以组织支持理论为基础,从工作情境和非工作情境两条路径,分析创业型领导通过工作激情和心理脱离对追随者创造力的影响机理,同时探究内隐追随对两条路径的调节效应。结果表明：创业型领导对创造力有显著正向预测作用,工作激情与心理脱离在创业型领导和创造力之间起中介作用。内隐追随在创业型领导与工作激情的情境路径中,以及在创业型领导与心理脱离非工作情境路径中均起正向调节作用,同时,内隐追随也调节工作激情和心理脱离的中介效应。研究结果揭示了不同情境传导机制下,创业型领导对追随者创造力正向作用的一致性,也丰富了创业型领导个体层面后果变量研究。     

Expensive martingales

We characterize strictly arbitrage-free markets of European options where only a discrete set of options is traded. We then construct martingales which reprice all given options and which are ‘most expensive’ among all martingales with this property. We also present algorithms to adjust real-life market data and to construct expensive martingales while taking into account additional ‘weak’ information: estimated prices of more exotic products such as, for example, forward started options.     

The law of one accounting variable

The ‘law of one accounting variable’ is defined in this paper as an extension of ‘the law of one price’. It says roughly that if the future payoffs of two assets are the same (in every state of the world), then the accounting variable of the assets are approximately the same. The paper derives a condition under which this law holds and shows that when the law holds for some accounting variables, these variables can replace betas in the multibeta representation of asset returns, provided some admissibility conditions are satisfied.     

Evaluating asset pricing models using the second Hansen-Jagannathan distance

We develop a specification test and a sequence of model selection procedures for non-nested, overlapping, and nested models based on the second Hansen-Jagannathan distance, which requires a good asset pricing model to not only have small pricing errors but also be arbitrage free. Our methods have reasonably good finite sample performances and are more powerful than existing ones in detecting misspecified models with small pricing errors but are not arbitrage-free and in differentiating models that have similar pricing errors of a given set of test assets. Using the Fama and French size and book-to-market portfolios, we reach dramatically different conclusions on model performances based on our approach and existing methods.
