Interaction of individual framing and political orientation in guiding climate change risk perception

There is a general agreement that climate change is a potential hazard threatening the global village. An appropriate level of risk perception should be a critical issue in coping with the global environmental risk. We examined the determinants of the level of climate change risk perception. In particular, we examined if individual framing of climate change interacts with political orientation in guiding climate change risk perception. The main effect of the two factors was also investigated. A nationwide online survey (N = 592) was conducted in South Korea by a professional survey agent. When self-efficacy, trust, and other demographics were controlled for, multiple regression analyses revealed that those focusing on what is happening (diagnostic framing) rather than what-to-do (prognostic framing) had higher risk perception. More importantly, only conservatives showed significantly different levels of risk perception according to their framing of the issue. Conservatives inclined to diagnostic framing showed higher risk perception than conservatives favoring prognostic framing. This difference disappeared when it comes to South Korean liberals, indicating an interaction between individual framing and political orientation. The significance of investigating individual framing, not media framing, and their interaction with political orientation are discussed.     

WAGE VOLATILITY AND CHANGING PATTERNS OF LABOR SUPPLY

Over the past few decades, the skilled–unskilled hours differential for U.S. men increased when the skill premium rose sharply, in contrast with dominant income effects. Based on PSID data, we show that over the 1967–2000 period, skilled men experienced a three times larger increase in wage volatility than unskilled men. With the rise in wage volatility, our general equilibrium incomplete markets model generates a 2.7 hours increase in the hours differential whereas it increased by 1.4 hours in the data. We find that hours adjustments are important for self‐insurance in the short run, whereas precautionary savings play a crucial role eventually.     

Capitalization of In‐Process Research and Development under SFAS 141R and Information Asymmetry

This study examines the effect of capitalizing acquired in‐process research and development (IPR&D) on information asymmetry under Statement of Financial Accounting Standards No. 141 (R) (SFAS 141R). SFAS 141R requires acquirers to fully recognize IPR&D at fair value as an indefinite‐lived intangible asset until completion or discontinuation of the project. Prior research suggests IPR&D capitalization will result in an improvement in the information environment. In contrast, we find no evidence that capitalizing IPR&D improved the information environment for IPR&D acquirers. Instead, most of our results suggest no significant change in information asymmetry for IPR&D acquirers during the post‐SFAS 141R period, relative to the concurrent changes for non‐IPR&D acquirers. In cases in which the results suggest a statistically significant increase, the economic magnitudes are relatively small. In addition, we find no evidence that IPR&D acquirers engaged in increased classification shifting between IPR&D and goodwill during the post‐SFAS 141R period, as critics of capitalization had feared.     

Investor attention and currency performance: international evidence

This article investigates the relationship between investor attention measured by Google search volume index and the performance of several currencies. We find that currency performance is remarkably responsive to changes in investor attention. These impacts, generated rapidly, are present over the relatively long term, especially for emerging currencies, and are intensified during periods of high uncertainty. We also demonstrate that there is a prominent asymmetric effect for the impact of attention, as past currency performance also influences attention. Typically, past currency performance can determine the magnitude of the impact on current currency performance. Moreover, we confirm that investor attention has a predictive power for forecasting emerging currency performance in the out-of-sample analysis. Further, these forecasts generate substantial economic value in the framework of asset allocation. By contrast, statistical predictability and economic value do not exist in the currencies from developed markets. These results indicate that investor attention can alter currency performance and its predictability. More broadly, our study emphasizes the potential of employing investor attention for emerging currency performance forecasting applications.

基于角色冲突的内部审计研究回顾与分析

本文梳理和分析了内部审计管理功能、治理功能及角色冲突方面的研究,指出现有研究过于强调内部审计的治理贡献,缺乏对内部审计同时服务于董事会和管理层所引发的角色冲突及其后果的深入分析.基于此,本文借鉴角色冲突的研究思路,对未来研究进行展望:一是多重委托代理关系下内部审计角色冲突的形成机理,二是角色冲突对内部审计行为后果的研究,试图通过角色冲突这一视角重新审视内部审计的治理功能和管理功能.     

深层卤水可采资源量评价的时间序列神经网络模型研究

深层地下卤水资源量的评价是国内外迄今尚未很好解决的课题,由于深部地质及水文地质参数难以准确获取,因此也难以对深层卤水资源量进行正确评价.从深层卤水开采量的时间序列出发,提出了一类基于神经网络的评价模型.首先分析了卤水开采量的时间序列特点,再建立了神经网络的拓扑结构,并设计了相应的评价算法,最后通过对某储卤构造的单井评价实例,对模型进行了验证.与传统的ARMA时间序列模型相比,其预测性能更好,对剩余可采资源量计算结果也更为准确.     

不同贸易方式技术溢出效应的比较——基于我国1987-2008年数据的实证研究

本文运用协整理论检验了我国1987-2008年间加工贸易进口和一般贸易进口的技术溢出效应.实证结果表明,加工贸易进口和一般贸易进口的技术溢出均对我国生产率起到了显著的促进作用,并且加工贸易进口的正向技术溢出效果远大于一般贸易进口的正向技术溢出效果.同时,加工贸易进口和一般贸易进口的技术溢出效应虽然长期显著地促进了我国生产率的增长,但这种正向技术溢出效应在短期内呈现出一定的滞后性.由于加工贸易进口在租金溢出效应、竞争效应与人力资本流动效应上的优势使得加工贸易进口的技术溢出效应大于一般贸易进口的技术溢出效应.
