Leading via the heart and mind: The roles of leader and follower emotions,attributions and interdependence

How do followers react to their leaders' emotional expressions, and how do these reactions influence followers' perceptions of their leaders' effectiveness? This research examines cognitive and emotional reactions to leaders' expressions of positive and negative emotions, and demonstrates how these reactions affect perceptions of leadership effectiveness. We show that follower interdependence (dispositional or manipulated) plays an important moderating role in understanding reactions to leaders' emotions. Results of three studies demonstrate that followers not only share their leaders' emotions, but also make attributions about the sincerity of their leaders' intentions, and these attributions affect their perceptions of their leader's effectiveness. Results also demonstrate that interdependent followers are sensitive to leader emotional valence and react more positively to leader positivity; non-interdependent followers do not differentiate positive from negative emotions in their leader. We discuss the implications of our research for the literature on leadership.     

Why does transformational leadership matter for employee turnover? A multi-foci social exchange perspective

Drawing on social exchange theory, the present study investigates the underlying mechanisms through which transformational leadership influences employee turnover. Leader–member exchange (LMX) and affective commitment (AC) are proposed as supervisor-based and organization-based social exchange mechanisms respectively, exemplifying how social exchange processes occur between an employee and his/her supervisor, and between the employee and his/her organization as a whole to underpin the effect of transformational leadership on turnover outcomes. Results of structural equation modeling on a sample of 490 full-time employees working in a large telecommunication company in the PRC provided support for the notion that transformational leadership is related to both social exchange mechanisms – LMX and AC – turnover intention and turnover behavior. Furthermore, the results revealed that AC rather than LMX mediated the link between transformational leadership and turnover intention. Turnover intention also only mediated the relationship between AC and turnover behavior over time.     

A process-oriented perspective of IS success: Examining the impact of IS on operational cost

Effective measurement of information system (IS) success continues to be a top concern for both practitioners and researchers. Labeled the “productivity paradox”, previous attempts to quantify the benefits of IS have often resulted in inconclusive or inconsistent results. The present study contributes to IS success research through the development and empirical testing of a process-oriented model of IS success. Using an operational perspective and combining primary and secondary measures, this study examines the influence of lower-level intangible IS and information technology (IT) benefits on higher-level financial measures. Additionally, we introduce IS plan quality as an antecedent to the model's input variables. Primary survey data from CIOs of primarily Fortune 2000 size firms are combined with secondary data, total operational cost, from Compustat to facilitate the examination of the IS benefits. This study also addresses shortcomings cited in other studies that might have contributed to the productivity paradox by including control variables in the model, defining a research perspective—the operational success perspective—and clearly articulating the level of analysis as the organizational level. The results supported a process-oriented view of the benefits from IS and showed how the effects of IS along a path can lead to better organizational performance, in this case, lower overall costs. These results are discussed and future research implications are presented.     

Structure of Uncertainty and Decision Making: An Experimental Investigation*

Decisions in the real world usually involve imprecise information or uncertainty about the precesses by which outcomes may be determined. This research reports the results of a laboratory experiment which examined whether the structure of uncertainty, namely, both the center and the range of the probability distribution describing the uncertainty, is an important determinant of choice. Specifically, it examines how the uncertainty of audit by the Internal Revenue Service of income tax returns affects taxpayers' decisions about intentional noncompliance. The context is relevant as almost nothing is known about how taxpayers assess detection risks using the probability information they have. The study focuses on intentional noncompliance. The factors affecting it are distinct and separate from those affecting unintentional noncompliance. Other factors that affect intentional tax noncompliance, such as risk, tax rates, and penalty rates, were controlled in the experiment. It was hypothesized that the lower the mean and the lesser the range (ambiguity) of the perceived audit probability, the greater the international noncompliance. As hypothesized, the analysis indicates that both the mean and the range of the perceived audit probability rate affect intentional noncompliance, though the effect of ambiguity is greater at a relatively higher level of mean. This result suggests that the strength of the information describing an uncertain event is captured better by both the mean and the range of the uncertainty than either of those components singly.
