Enhancing Stock Market Return with New Product Preannouncements: The Role of Information Quality and Innovativeness

To advance development and application of signaling theory in the new product preannouncement literature while seeking to resolve ambiguity regarding the influence of innovativeness on stock market return, the role of information quality is examined. Specifically, this study investigates the effect of innovativeness across low and high levels of information quality. The results, ascertained using event study methodology on a sample of 243 new product preannouncements collected over a nine‐year period, indicate that higher information quality increases the strength of the positive relationship between innovativeness and stock market return. The findings offer managers insight into what role information quality plays in new product preannouncements that can help their firms generate higher stock market return.     

The welfare costs of monopoly are larger than you think

We show that monopoly is the parent of monopsony when an industry employs specialized resources. This means that the welfare loss from monopoly and monopolization is larger than commonly portrayed. Copyright © 2010 John Wiley & Sons, Ltd.     

Recursive Formula for Arithmetic Asian Option Prices

I derive a recursive formula for arithmetic Asian option prices with finite observation times in semimartingale models. The method is based on the relationship between the risk‐neutral expectation of the quadratic variation of the return process and European option prices. The computation of arithmetic Asian option prices is straightforward whenever European option prices are available. Applications with numerical results under the Black–Scholes framework and the exponential Lévy model are proposed. © 2012 Wiley Periodicals, Inc. Jrl Fut Mark 34:220–234, 2014     

Examining the relations between open innovation climate and job satisfaction with a PLS path model

The paper studies the relations between open innovation climate and job satisfaction, in particular the causal effects of the various dimensions of open innovation climate on different facets of job satisfaction. We assume firms which pursuing open innovation climate will result in higher level of employee job satisfaction. Both open innovation climate and job satisfaction are assumed to be multidimensional constructs (second-order model). Meanwhile the difference caused by employees’ organizational level was also investigated. A partial least squares path model was developed, in which significant effects were discovered. This study provides valuable materials for hoteliers who want to promote open innovation climate in their organizations.     

Engagement partner specialization and corporate disclosure transparency

This paper explores the association of audit partners' industry specialization with corporate disclosure transparency and the latter's informativeness. The distinctive institutional designs of partner signature requirement and Information Disclosure and Transparency Ranking System (IDTRS) adopted in Taiwan allow us to empirically address the issue. We posit and find that the rankings from the IDTRS are higher for firms audited by industry specialist engagement partners than for firms audited by non-specialist engagement partners. Additionally, the results show that the probability of informed trade (PIN) proxy for information asymmetry is negatively associated with the rankings for clients of industry specialist engagement partners, but not for clients of industry non-specialist engagement partners. The results are robust with respect to alternative estimation method and alternative measures of industry specialization. Overall, the evidence suggests that industry specialist engagement partners enhance the credibility of corporate disclosure transparency, through which information asymmetry is further declined. The evidence provides policy implications to the partner signature requirement adopted in Taiwan and China.     

Marrying personality and job resources and their effect on engagement via critical psychological states

This study examined the process by which individuals become engaged with their jobs by integrating seminal engagement theory. More specifically, we suggest that an individual factor (i.e. autotelic personality) and two contextual factors (i.e. feedback environment, job autonomy) interact to predict work engagement through three critical psychological states – namely availability, meaningfulness, and safety. This moderated mediation framework was tested using a cross section of the US population (n = 284); data were collected at two points in time with 3 months in between. Availability and meaningfulness mediated the relationship between autotelic personality and work engagement. Autotelic personality’s indirect effect on work engagement through meaningfulness and safety was conditional such that the nature of feedback environment’s effect depended on job autonomy level. Theory and practice implications are discussed.     

Consumer perception,information provision,and regulation of insurance markets

Available evidence shows that consumers overinsure against modest risks. For instance, a majority of consumers tend to choose too low a level of deductible for homeowners insurance and automobile insurance, and purchase excessive warranties for electronics and other durable products such as automobiles and furniture. The analysis demonstrates that overinsurance decreases consumer welfare and increases insurers’ profits. This tendency of overinsurance stems from lack of information about the probability and magnitude of loss, and it calls for policies that require insurers or third-party organizations to provide more, albeit not perfect, information and data for consumers before they make insurance-purchase decisions. The implications of the analysis for other financial products such as stocks and deposits are discussed.
