Purpose: While extant key account management (KAM) research provide considerable insight into specific aspects of KAM, no studies have yet offered a process model that concurrently addresses the three important characteristics of KAM (i.e., temporality, dyadic interactions, and account heterogeneity). To fill this void, the present research investigates an industrial seller's KAM practice from the alignment perspective to develop a comprehensive process model that depicts the important underlying characteristics of focal firm–key accounts dyadic relationships. Methodology: Employing a case study approach, the present study adopts in-depth interviews with eleven informants involved in four dyadic relationships, respectively. Multiple dyads interviews helped us determine whether the emergent themes are resonant across dyads. On the other hand, cross-dyad analysis helped us identify idiosyncratic KAM treatment among heterogeneous key accounts. Findings: Drawing upon the literature and the field data, this study reveals four different patterns of alignment (i.e., opportunistic alignment, passive alignment, mutualistic alignment, and compensatory alignment) that may be enacted in accordance with the different relationships developed with the individual key accounts. Across the four focal firm–key account dyads, this study further uncovers how various factors (i.e., idiosyncratic investment, power structures, behavioral norms, and commitment) precipitate different alignment patterns and drive alignment transitions over time. Practical Implications: This article suggests that a focal firm should manage its key accounts by aligning its value proposition with the specific desired value of each individual account and adjust its management approach based on different phases of dyadic relationship development. Originality Value: This article extends knowledge of KAM by concurrently addressing its dyadic and heterogeneous nature in a process model. The alignment-oriented view of KAM sheds light on the underlying characteristics of focal firm–key accounts relationships and contributes to our understanding of managing key account portfolios throughout the process of relationship development. 相似文献

On 20 February 2012, the Taiwan Stock Exchange Corporation launched an order-matching simulation mechanism for five minutes during the start of the pre-closing session, in order to increase information disclosure during this period (13:25–13:30). Pre-closing information disclosure significantly reduces both trading costs and closing-price volatility, as well as price manipulation. The decrease in price manipulation found in this work is due to pre-closing information disclosure, not the behaviour of investors shifting to an earlier time. Further, if a stock price rises or falls by more than 3.5% in the simulation in the last minute during the closing session, trading of the stock will be suspended for two minutes from 13:31 to reduce volatility. However, this trading mechanism (suspended-closing) does not seem to have achieved the intended goals of the authorities, as it has not been able to significantly reduce closing-price volatility and price manipulation. 相似文献

This paper investigates mega hedge fund management companies that collectively manage over 50% of the industry's assets, incorporating previously unavailable data from those that do not report to commercial databases. We find similarities among mega firms that report performance to commercial databases compared with those that do not. We show that the largest divergences between the performance of reporting and nonreporting mega firms can be traced to differential exposure to credit markets. Thus, the performance of hard-to-observe mega firms can be inferred from observable data. This conclusion is robust to delisting bias and the presence of serially correlated returns. 相似文献

A censored stochastic volatility model is developed to reconstruct a return series censored by price limits, one popular form of market stabilization mechanisms. When price limits are reached, the observed prices are truncated and the equilibrium prices are unobservable, which makes further financial analyses difficult. The model offers theoretically sound estimates of censored returns and is demonstrated via simulations to outperform existing approaches with respect to the estimates of model parameters, unconditional means, and standard deviations. The algorithm is applied to model stock and futures returns and results are consistent with the simulation outcomes. 相似文献

Self-service technologies (SSTs) have enhanced the role technology plays in customer interactions with firms, yet instruments that systematically measure the service quality of SSTs from the perspective of customers remain underdeveloped. Based on psychometric scale development approaches, this study conceptualized, constructed, refined, and tested a multiple-item scale that examined key factors influencing SST service quality. Through qualitative and quantitative studies in four separate phases, a 20-item seven-dimension SSTQUAL scale was developed that includes functionality, enjoyment, security, assurance, design, convenience, and customization. The scale demonstrates sound psychometric properties based on findings from various reliability and validity tests as well as vigorous scale replications across industries and consumer traits using several different samples. The utility of the proposed scale is discussed for implications, limitations and future research. 相似文献

We consider processes with second order long range dependence resulting from heavy tailed durations. We refer to this phenomenon as duration-driven long range dependence (DDLRD), as opposed to the more widely studied linear long range dependence based on fractional differencing of an i.i.d. process. We consider in detail two specific processes having DDLRD, originally presented in Taqqu and Levy [1986. Using renewal processes to generate long-range dependence and high variability. Dependence in Probability and Statistics. Birkhauser, Boston, pp. 73–89], and Parke [1999. What is fractional integration? Review of Economics and Statistics 81, 632–638]. For these processes, we obtain the limiting distribution of suitably standardized discrete Fourier transforms (DFTs) and sample autocovariances. At low frequencies, the standardized DFTs converge to a stable law, as do the standardized sample autocovariances at fixed lags. Finite collections of standardized sample autocovariances at a fixed set of lags converge to a degenerate distribution. The standardized DFTs at high frequencies converge to a Gaussian law. Our asymptotic results are strikingly similar for the two DDLRD processes studied. We calibrate our asymptotic results with a simulation study which also investigates the properties of the semiparametric log periodogram regression estimator of the memory parameter. 相似文献

The issue of authentic leadership has been generating increased interest in both practical and academic domains. This study examines the influence of authentic leadership on employee trust and employee work engagement from the dyadic supervisor–employee viewpoint. The sample data consists of responses from 77 team supervisors and 345 employees in 36 companies. We utilize hierarchical linear modeling to test the hypotheses. The cross-level results show that employee trust fully mediates supervisor-perceived authentic leadership and employee work engagement, and that employee-perceived authentic leadership fully mediates the relationship between supervisor-perceived authentic leadership and employee trust, as well as the relationship between supervisor-perceived authentic leadership and employee work engagement. On the individual level, employee trust has a partial mediating effect on the relationship between employee-perceived authentic leadership and employee work engagement. 相似文献

Competitive pricing decisions in a two-echelon supply chain with horizontal and vertical competition
Cheng-Han WuChieh-Wan Chen Chung-Chi Hsieh 《International Journal of Production Economics》2012,135(1):265-274
This study investigates the pricing decisions in a non-cooperative supply chain that consists of two retailers and one common supplier. The retailers order from the common supplier and compete in the same market. We analyze six power structures that characterize exclusively horizontal competition between the retailers and vertical competition between the supplier and the retailers, leading to different sequences of moves among the chain members. We derive the analytical forms of the equilibrium quantities under each power structure and explore the effect of retail substitutability on the equilibrium quantities among all power structures. We further investigate the performances of the game models as compared with the integrated model. 相似文献
