Asymmetrical reaction to US stock-return news: evidence from major stock markets based on a double-threshold model

This paper examines the hypothesis that both stock returns and volatility are asymmetrical functions of past information from the US market. By employing a double-threshold GARCH model to investigate six major index-return series, we find strong evidence supporting the asymmetrical hypothesis of stock returns. Specifically, negative news from the US market will cause a larger decline in a national stock return than an equal magnitude of good news. This holds true for the volatility series. The variance appears to be more volatile when bad news impacts the market than when good news does.     

Exploring the roles of self-concept and future memory at consumer events: the application of an extended Mehrabian–Russell model

This study aimed to extend Mehrabian and Russell’s stimulus–organism–response (S-O-R) framework to consumer events. Physical environment and staff interaction were evaluated as stimuli which impact event attendees’ self-concept and memory (organism), and lead to behavioral intention (response). Data were collected from the surveys completed by 449 attendees of Armada event. The findings confirmed the impact of physical environment on self-concept and memory, as well as the mediation effect of memory between self-concept and behavioral intention. The study is a pioneer in the application of an extended S-O-R framework with the inclusion of memory.     

Analyzing yield, duration and convexity of mortgage loans under prepayment and default risks

In this article, we construct a general model, which considers the borrower’s financial and non-financial termination behavior, to derive the closed-form formula of the mortgage value for analyzing the yield, duration and convexity of the risky mortgage. Since the risks of prepayment and default are reasonably expounded in our model, our formulae are more appropriate than traditional mortgage formulae. We also analyze the effects of the prepayment penalty and partial prepayment on the yield, duration and convexity of a mortgage, and provide lenders with an upper-bound for the mortgage default insurance rate. Our model provides portfolio managers a useful framework to more appropriately appraise the mortgage and more effectively hedge their mortgage holdings. From the results of sensitivity analyses, we find that higher interest-rate, prepayment and default risks will increase the mortgage yield and reduce the duration and convexity of the mortgage.     

Targeting Teaching Lecture Capture Learning: Do Students Perform Better Compared to Face‐to‐Face Classes?

Online learning has become more prevalent in colleges and universities as new technology is introduced. One such technology is lecture capture, which allows a live lecture to be recorded and packaged with classroom media and delivered online to many more students than a traditional face‐to‐face class. This article studies the selection process and educational outcome differences between students enrolled in a lecture capture and a face‐to‐face course in economic principles. Students could select either course format, both with the same instructor and course requirements, without capacity restrictions. We find that students’ attitudes toward online learning are the chief determinant of their choice of class over demographics, opportunity cost measures, or past online experiences. Additionally, our findings suggest that lecture capture students perform as well as those who take a face‐to‐face course when not accounting for self‐selection. When selection is taken into account, lecture capture is not significantly worse than face‐to‐face.     

Do aggressive funds reallocate their portfolios aggressively?

This study examines pairs of asset allocation mutual funds that are controlled for all informational attributes, except for the level of risk aversion. Standard mean‐variance models of portfolio choice suggest that the percentage rebalancing of common stocks in aggressive funds would be the same as that in conservative funds. However, this study finds the rebalancing of common stocks in aggressive funds to be disproportionally less intense.
