We empirically analyze the impact of economic uncertainty due to the COVID-19 pandemic on the trading volume of each sector in the S&P 500 index. Wavelet coherence analysis is carried out using economic policy uncertainty data and the trading volume of each sector in the S&P 500 index from July 2004 to September 2020. Furthermore, we apply multifractal detrended fluctuation analysis to the trading volume series of all sectors. The wavelet coherence analysis shows that the COVID-19 pandemic has substantially influenced (...) trading volume in all sectors. However, the impact of the pandemic is different from that during the global financial crisis in some sectors, such as information technology, consumer discretionary, and communication services. Because of the lockdown taken to suppress COVID-19, increased remote working and remote learning are the main reasons for these results. Additionally, according to the MF-DFA analysis, the trading volume of all the sectors has clear multifractal characteristics, and they are all nonpersistent. Specifically, trading volumes of the real estate and materials sector are highly correlated, whereas the trading volumes of industry and information technology sectors are comparatively less correlated.

This study investigates the relationship among ethical philosophy, thinking style, and managerial ethical decision-making. Based on the premise that business ethics is a function of culture and time, we attempt to explore two important questions as to whether the national differences in managerial ethical philosophies remain over time and whether the relationship between thinking style and ethical decision-making is consistent across different national contexts. We conducted a survey on Korean managers’ ethical decision-making and thinking style and made a cross-cultural, cross-temporal (...) comparison with the results presented by previous studies that surveyed Korean and US managers with the same questionnaire at different points in time. Our analysis revealed that Korean managers have become more reliant on rule utilitarianism for ethical decision-making over the last two decades, which is dominantly used by US managers, corroborating our convergence hypothesis built on social contracts theory. However, as opposed to previous research, we found that managers with a balanced linear and nonlinear thinking style do not necessarily make more ethical decisions compared to those with a predominantly linear or nonlinear thinking style. This study contributes to international business ethics literature by presenting a theoretical framework that may explain the convergence of ethical philosophies employed by managers in different national contexts over time, and that the relationship between thinking style and managerial ethical decision-making may not be universal, but contingent on contextual factors.

『모호한 군중』은 현대인의 도덕성에 전하는 철학적 메시지를 담았다. 바쁜 일상 속에서 자칫 잊기 쉬운 ‘그대 안의 도덕성’을 일깨워야 한다는 저자의 외침들은 우리로 하여금 많은 생각을 하게 한다.

Using 2003 Asian Barometer Survey study data, this paper examines the economic voting model in the 2002 presidential election in South Korea. The core emphasis of the paper is on an investigation of the relative effects of different dimensions/scopes of economic evaluations on voting behavior, namely whether one form of assessment (e.g., pocketbook vs. sociotropic) can have similar consequences for electoral participation as others. The findings indicate that the overall economy is salient for Koreans to shape their political choices. In (...) other words, voting behavior in Korea depends on how she or he thinks the national economy has been for the past five years. Also found is that voters’ perceptions of their own personal financial situations did not matter much as a predictor of voter choice. (shrink)
