TL;DR: In this article, two experimental studies reveal the existence of a strong, positive impact of customer satisfaction on willingness to pay, and they provide support for a nonlinear, functional structure based on disappointment theory (i.e., an inverse S-shaped form).
Abstract: Two experimental studies (a lab experiment and a study involving a real usage experience over time) reveal the existence of a strong, positive impact of customer satisfaction on willingness to pay, and they provide support for a nonlinear, functional structure based on disappointment theory (i.e., an inverse S-shaped form). In addition, the second study examines dynamic aspects of the relationship and provides evidence for the stronger impact of cumulative satisfaction rather than of transaction-specific satisfaction on willingness to pay.

TL;DR: A meta-analysis was conducted to estimate the true correlation between attitudinal organizational commitment and job performance and to identify moderators of this correlation as mentioned in this paper, finding that the correlation was at least marginally significantly stronger for extra role performance as opposed to in-role performance.
Abstract: A meta-analysis was conducted to estimate the true correlation between attitudinal organizational commitment and job performance and to identify moderators of this correlation. One-hundred and eleven samples from 93 published studies were included. The corrected mean correlation was 0.20. The correlation was at least marginally significantly stronger for: (a) extra-role performance as opposed to in-role performance; (b) white-collar workers as opposed to blue-collar workers; and (c) performance assessed by self ratings as opposed to supervisor ratings or objective indicators. Four other assumed moderators (commitment measure: Affective Commitment Scale versus Organizational Commitment Questionnaire, job level, age, and tenure) did not have at least marginally significant effects.

TL;DR: In this paper, a simulation study compared maximum likelihood (ML) estimation with weighted least squares means and variance adjusted (WLSMV) estimation and found that with 2 and 3 categories the rejection rates corresponded much more to the expected rejection rates according to an alpha level of.
Abstract: This simulation study compared maximum likelihood (ML) estimation with weighted least squares means and variance adjusted (WLSMV) estimation. The study was based on confirmatory factor analyses with 1, 2, 4, and 8 factors, based on 250, 500, 750, and 1,000 cases, and on 5, 10, 20, and 40 variables with 2, 3, 4, 5, and 6 categories. There was no model misspecification. The most important results were that with 2 and 3 categories the rejection rates of the WLSMV chi-square test corresponded much more to the expected rejection rates according to an alpha level of. 05 than the rejection rates of the ML chi-square test. The magnitude of the loadings was more precisely estimated by means of WLSMV when the variables had only 2 or 3 categories. The sample size for WLSMV estimation needed not to be larger than the sample size for ML estimation.
